CCPIA / InterNACHI Standards of Practice

InterNACHI promotes these Standards in collaboration with its sister organization, the Certified Commercial Property Inspectors Association (CCPIA). InterNACHI is a non-profit corporation dedicated to advancing the cause of consumers and its membership through education. The purchase of a property is typically the most significant investment that consumers make, and that investment needs to be protected. As a consequence, thousands of inspections are conducted daily that result in the production of legal documents, such as inspection reports, contracts, and a variety of agreements, and it is essential therefore that consumers understand what a property inspection does include and what it does not include.

InterNACHI property inspectors are professional individuals who in exchange for a fee agree to accept the responsibility of evaluating and reporting on the interrelated conditions and components of a property with a “degree of care that a reasonably prudent home inspector would exercise,” Inspection is defined as “a non-invasive physical examination, performed for a fee in connection with the transfer … of a property,” undertaken in an attempt to identify “material defects” that could significantly “affect the value, desirability, habitability, or safety of the dwelling.” However, even this definition is subject to interpretation and debate, and what constitutes a InterNACHI inspection needs to be explained and clearly understood, for practical, ethical, and legal purposes. To borrow an example from medicine, an InterNACHI property inspector is similar to a general practitioner, who has learned a lot about medicine and the human body but has not specialized in any one particular discipline. Similarly, InterNACHI inspectors know a lot about the building trades, such as roofing, plumbing, heating, air-conditioning, and electrical, but they are not licensed specialists. In fact, like general practitioners, it is their responsibility to defer to specialists. For this reason, InterNACHI property inspections are limited in their scope.

InterNACHI property inspections are “non-invasive” and essentially visual and, as stated, are intended to alert consumers in a “written report” to “material defects” that exist at the time of an inspection, defects that could significantly affect the value of a property or pose a threat to health and safety. A property inspection is not technically exhaustive, and is not intended to be, and will not reveal every defect and deficiency. For instance, a property inspection does not include research to establish code-compliance, recall notices, or prior reports. Therefore, an inspection report should not be regarded as a substitute for the seller’s transfer disclosure statement (TDS), which the sellers are required to provide by the Business and Professions Code, or as an insurance policy, warranty, or guaranty. Some defects may be latent, and/or become apparent at a later point in time, which is why inspections have been sensibly characterized as snapshots in time. And it is essential that consumers understand this and, thereby, have reasonable expectations. However, the terms “non-invasive” and “visual” also need further explanation. For example, an inspector may remove the interior cover from an electrical panel, which could be said to be invasive, and inserting an electrical tester into a wall outlet could be construed as being more than a visual examination. Regardless, most inspectors remove cover panels and use a variety of specialized instruments in the service of their clients, but the use of such instruments does not distinguish them as specialists; only a licensing authority can legitimately confer that distinction. InterNACHI inspectors adhere to clearly defined standards and state laws, and to this extent InterNACHI standards are intended to be legally binding.

 

PURPOSE AND SCOPE

1.1.

1.  Purpose
1.1  The purpose of this document is to define best practices and to
establish a reasonable approach for the performance of an
inspection of a commercial property.

A commercial inspection is a non-invasive, visual examination of the accessible areas of a residential property (as delineated below), performed for a fee, which is designed to identify defects within specific systems and components defined by these Standards that are both observed and deemed material by the inspector. The scope of work may be modified by the Client and Inspector prior to the inspection process.

  • The commercial inspection is based on the observations made on the date of the inspection, and not a prediction of future conditions.
  • The commercial inspection will not reveal every issue that exists or ever could exist, but only those material defects observed on the date of the inspection.

1.2.
A material defect is a specific issue with a system or component of a residential property that may have a significant, adverse impact on the value of the property, or that poses an unreasonable risk to people. The fact that a system or component is near, at or beyond the end of its normal useful life is not, in itself, a material defect.

1.3.
A commercial inspection report shall identify, in written format, defects within specific systems and components defined by these Standards that are both observed and deemed material by the inspector. Inspection reports may include additional comments and recommendations. Inspectors will report on required items only when a defect is found.

 

LIMITATIONS, EXCEPTIONS & EXCLUSIONS

2.1. Limitations:

  • An inspection is not technically exhaustive. This means that we do not diagnose the condition of components in a house beyond their function with normal operator controls. If a component does not work, further evaluation and/or repair will be noted in the report.
  • An inspection does not guarantee a property will be free of defects, or that all defects will be reported/observed within a limited time frame and scope. There is no insurance nor coverage of any kind of repairs.
  • An inspection will not identify concealed or latent defects. These are defects that are not apparent on the day of the inspection, or those defects that manifest after the inspection. An example is a furnace that works on the day of inspection, but fails after the inspection. Another example is a drain line that flows when the inspector runs clear water, but gets clogged with the use of toilet paper, soap, food items, etc.
  • An inspection will not deal with aesthetic concerns or what could be deemed matters of taste, cosmetic defects, etc. Examples of excluded items includes paint, stains on flooring material, worn finishes on cabinets, doors, or decorator items such as curtains, curtain rods, blinds, etc.
  • An inspection will not determine the suitability of the property for any use.
  • An inspection does not determine the market value of the property or its marketability.
  • An inspection does not determine the insurability of the property.
  • An inspection does not determine the advisability or inadvisability of the purchase of the inspected property.
  • An inspection does not determine the life expectancy of the property or any components or systems therein. Everything in a house can wear out. This includes appliances, HVAC equipment, roofing material, faucets and other plumbing fixtures, door locks and hardware, flooring, window hardware, etc. Just like an older car, parts wear out and a home inspection is not intended to determine the life remaining.
  • An inspection does not include items not permanently installed. Examples include refrigerators, clothes washing and drying equipment, electrical equipment attached to a receptacle (timers, TV’s, water feature pumps, windows AC units, room heaters). * Building Supporters High-Performance standards include inspection and recall check (when data is available) including: Refrigerators, clothes washing and drying equipment, dishwashers, and trash compactors.
  • These Standards of Practice apply only to properties with four or fewer residential units.

2.2.Exclusions:

I. The inspector is not required to determine:

  • Property boundary lines or encroachments.
  • The condition of any component or system that is not readily accessible.
  • The service life expectancy of any component or system.
  • The size, capacity, BTU, performance or efficiency of any component or system. We rely on the builder having installed items according to codes in place at the time of construction. Inspectors do not calculate capacities or efficiency of any items such as HVAC equipment, pool heating and pumping equipment, solar (heating or PV).
  • The cause or reason of any condition.
  • The cause for the need of correction, repair or replacement of any system or component.
  • Future conditions.
  • Compliance with codes or regulations. Due to changing building codes on a nearly annual basis, it is impossible for a home inspector to know the exact codes in place at the time of construction. It is not reasonable to hold an older home to today’s building standards. While there are obvious right and wrong ways of installing items or building homes, we specifically do not cite codes within the scope of a home inspection.
  • The presence of evidence of rodents, birds, animals, insects, or other pests.
  • The presence of mold, mildew or fungus. * Building Supporters high-performance standards include a visual mold assessment. Building Supporters also offers an auxiliary mold testing service as an add-on service, for an additional fee.
  • The presence of airborne hazards, including radon. Colorado has a high occurrence of Radon, and * Building Supporters therefore offers an auxiliary radon testing service as an add-on service, for an additional fee.
  • The air quality.* Building Supporters offers air sampling and testing as an add-on service, for an additional fee.
  • The existence of environmental hazards, including lead paint, asbestos or toxic drywall. * Building Supporters offers material sampling and testing as an add-on service, for an additional fee.
  • The existence of electromagnetic fields.
  • Any hazardous waste conditions.
  • Any manufacturers’ recalls or conformance with manufacturer installation, or any information included for consumer protection purposes. * Building Supporters High-Performance standards include a recall check (when data is available) for: HVAC equipment, hot water heaters, refrigerators, clothes washing and drying equipment, dishwashers, and trash compactors.
  • Acoustical properties.
  • Correction, replacement or repair cost quotes.
  • Quotes of the cost to operate any given system.

II. The inspector is not required to operate:

  • any system that is shut down.
  • any system that does not function properly.
  • or evaluate low-voltage electrical systems such as, but not limited to:
    1. Phone lines
    2. Cable lines
    3. Satellite dishes
    4. Antennae
    5. Lights
    6. Remote controls
  • Any system that does not turn on with the use of normal operating controls.
  • Any shut-off valves or manual stop valves.
  • Any electrical disconnect or over-current protection devices. Home inspectors do not test circuit breakers to determine their effectiveness at times of over-load. A licensed electrician has the specialized tools for this. If you are buying an older home and are concerned about the functionality of breakers, you should have the electrical panel and the breakers tested by a licensed electrician.
  • Any alarm systems.
  • Moisture meters, gas detectors or similar equipment. * Building Supporters High-Performance standards include a Infrared Thermography Survey and the use of moisture meters based on thermal findings. Gas leak detection is included in Building Supporters High-Performance standards.

III. The inspector is not required to:

  • Move any personal items or other obstructions, such as, but not limited to: throw rugs, carpeting, wall coverings, furniture, ceiling tiles, window coverings, equipment, plants, ice, debris, snow, water, dirt, pets, or anything else that might restrict the visual inspection.
  • Dismantle, open or uncover any system or component.
  • Enter or access any area that may, in the opinion of the inspector, be unsafe. This is solely left to the discretion of the home inspector. An area may be deemed unsafe to enter due to limited clearance, animals, pests, standing water, poor electrical installations, animal waste, laceration hazards, or any other item deemed to be a hazard. This includes yards, side yards, crawl spaces, attics, rooms, garages, or storage rooms.
  • Enter crawlspaces or other areas that may be unsafe or not readily accessible.
  • Inspect underground items, such as, but not limited to: lawn-irrigation systems, underground storage tanks or other indications of their presence, whether abandoned or actively used.
  • Do anything which may, in the inspector’s opinion, be unsafe or dangerous to the inspector or others, or damage property, such as, but not limited to: walking on roof surfaces, climbing ladders, entering attic spaces, or negotiating with pets.
  • Inspect decorative items. This includes curtains, blinds, furniture, and hanging or stationary art.
  • Inspect common elements or areas in multi-unit housing. If a component is not the property of the seller, it will not be inspected such as the roof of a condominium or townhouse, exterior stairs, pools, railings, stucco, decks, or any common area items.
  • Inspect intercoms, speaker systems or security systems.
  • Offer guarantees or warranties. * Building Supporters does offer a guarantee. Please use our search box above by typing the word “guarantee” for details.
  • Offer or perform any engineering services. This means that we do not calculate the load-bearing ability of any structure or determine any structural components for adequacy. Home inspectors rely on the builder having built the house to code and according to plans in place at the time of construction. If a part of the structure appears inadequate, the inspector will note it in the report for further evaluation. This includes deck structures, floor structures and roof structures.
  • Offer or perform any trade or professional service other than general home inspection. * Building Supporters offers an auxiliary building problem solving service as an add-on service, for an additional fee.
  • Research the history of the property, or report on its potential for alteration, modification, extendibility or suitability for a specific or proposed use for occupancy. * Building Supporters standard includes a BUILDFAX property history report when data can be found in the searchable database.
  • Determine the age of construction or installation of any system, structure or component of a building, or differentiate between original construction and subsequent additions, improvements, renovations or replacements.
  • Determine the insurability of a property.
  • Perform or offer Phase 1 or environmental audits. * Building Supporters offers an auxiliary service as an add-on service, for an additional fee.
  • Inspect any system or component that is not included in these Standards.

STANDARDS OF PRACTICE

4.  Inspection
4.1  Objective
The objective of an inspection is to provide written communication describing the issues discovered from observations made and research conducted by the inspector, which, in the inspector’s opinion, are likely to be of interest to his/her client, and to enhance the client’s information and knowledge about the commercial property to improve decision-making for buying, selling, maintaining or improving the property.
4.2  Who May Perform the Inspection
Any portion of the inspection, including the walk-through survey, research and report-generation, may be performed by the inspector, his/her staff, or any consultant hired by the inspector.  This Standard recognizes that, for the majority of commercial inspections, the inspector is likely an individual with a general, well-rounded knowledge of commercial properties, and that the inspector or client may want to augment the inspector’s skills with specialty consultants who have particular expertise in certain areas.  The decision to hire specialty consultants will, of course, rely on budget and time constraints, as well as the risk-tolerance of the client.
4.3  Varying Levels of Due Diligence
This Standard is designed as a baseline from which the inspector and client can develop and agree to a scope of work that may deviate from this Standard, depending on budget, time constraints, purpose of the inspection, age of the subject property, and risk-tolerance of the client.  The level of due diligence should be set where the cost, in time and money, of acquiring information about the subject property will not likely exceed the value of that information.  Therefore, an inspection performed in accordance with this Standard will not be technically exhaustive.
4.3.1  Sample Language for Use When Defining the Scope of
Work
“The inspection will be performed in accordance with InterNACHI-CCPIA ComSOP, except that…”
4.3.2  Representative Observations
In recognizing that the client likely has the goal of acquiring information about the subject property at a cost, in time and money, that does not exceed the value of that information, representative observations are not just permitted by this Standard, but recommended, as well.
4.4  Uncertainty
The client should understand that no inspection report is completely accurate.  A report is only the written communication of the observations made and research conducted by the inspector.  The report contains those items which, in the inspector’s opinion, are likely to be of interest to his/her client.
4.5  Subjectivity
The client should understand that the inspection report is, to a large degree, the subjective opinions of the inspector based on his/her observations and research within the limits of access, time and budget, and without the aid of special equipment or meters, and without dismantling, probing, testing or troubleshooting, and without detailed knowledge of the commercial property, its components or its systems.  The inspection report is not much more than a subjective professional opinion.
4.6  Not an Architectural or Engineering Service
An inspector performing a commercial inspection in accordance with this Standard is not practicing architecture or engineering.
4.7  Not a Warranty, Guarantee or Insurance Policy
The inspection is not a warranty, and the inspection report is merely the written communication of the inspector’s subjective opinion on the condition of the subject property.
5.  Research
5.1  Objective
The objective of research, including the review of documents and the performing of interviews, is to augment the information obtained during the walk-through survey and to provide supporting documentation to the inspection report.
5.2  Document Procurement
It is the client’s responsibility to obtain copies of all documents and provide them for the inspector.  These documents are most often obtained from the seller or from local government offices.  The inspector is not responsible for gathering or paying for copies of appropriate documents to be reviewed unless these tasks are specifically assigned to the inspector in the Scope of Work Agreement.
5.3  Documents to Be Reviewed and Included in the Inspection Report
The inspector should review all documents provided by the client and owner.  The inspector should also make an inquiry and review of any other documents that can be reasonably procured on-site or from the building owner or manager, such as Certificates of Occupancy, building code violation notices, repair invoices, and warranties.  The inspector is not required to uncover and review information that is not provided or cannot be reasonably ascertained or acquired on-site.  Copies of documents that the inspector believes may be of interest to the client and copies of documents that support the inspector’s opinions should be included in the inspection report.
5.3.1 Examples of documents the inspector may want to request for review:
  • accessibility surveys;
  • appraisals;
  • building plans;
  • Certificates of Occupancy;
  • citations;
  • deck age records, plans and construction permits;
  • deck and balcony maintenance, power-washing, painting, treating, repair and modification history;
  • emergency evacuation plans;
  • environmental studies;
  • evacuation drill records;
  • fire-detection test and maintenance records;
  • fire door inspection reports;
  • fire-prevention plans;
  • fire extinguisher service records;
  • fire records;
  • flame-resistant certificates;
  • floodplain maps;
  • floor plans;
  • kitchen grease-cleaning records;
  • kitchen post-fire inspections;
  • maintenance records;
  • manufacturers’ installation instructions;
  • notices;
  • permits;
  • power-washing records;
  • previous inspection reports;
  • proposals;
  • rent records;
  • repair estimates/invoices;
  • safety inspection records;
  • seller disclosures;
  • sprinkler head replacement records;
  • utility bills; and
  • warranties.
5.4  Interviews
The inspector should identify and interview the person(s) with the most knowledge about the condition of the building.  Typically, this will be the building owner or manager.  Unless otherwise agreed to in the Scope of Work Agreement, it is the responsibility of the client to arrange to have such person(s) on hand for interview by the inspector on the day of the walk-through survey.
5.5  Pre-Inspection Questionnaires
The inspector may request that the owner, building manager and/or client fill out pre-inspection questionnaires to gather information.  The inspector may rely that these responses are truthful.  In cases where parties refuse to fill out questionnaires in writing, the inspector may interview the parties and fill out the questionnaires for them.  The inspector should note in the report if s/he filled out the questionnaire based on an interview and whether such interview was performed in person, by telephone, or by email.  Copies of all responses to such questionnaires should be included in the inspection report.
5.6  Reliance
The level of accuracy of information varies, depending on its source.  The inspector may rely on information obtained to the extent that the information appears to be accurate and complete.  This Standard does not require the inspector to independently verify the accuracy of the documents reviewed by the inspector or included in the report, nor the statements made by those interviewed by the inspector.
5.7  Fraud
The inspector is not a fraud investigator, and this Standard does not require the inspector to look for intentionally hidden deficiencies in the subject property.  The inspection report is supplementary to the seller’s disclosures.
5.8  Previously Generated Reports
A previously generated inspection report should be treated no differently than any other document reviewed during the research portion of the inspection, and, as with information collected from any other source, information obtained from a previously generated report should reference its source in the new inspection report.  No portion of a previously generated report should be used as a substitute for the new inspection report.
6.  Walk-Through Survey
6.1  Objective
The objective of the walk-through survey is to allow the inspector to visually observe the subject property, gather information, and note items of interest.
6.2  Access Responsibility
It is the client’s responsibility to arrange for the inspector to receive timely access to the subject property for the walk-through survey portion of the inspection, as well as access to all documents and interviewees needed for the research portion of the inspection.  This includes access to all documents, information and previously generated reports in the client’s possession.  The inspector is not responsible for obtaining, reviewing or providing information, should the source withhold, impede or delay access.  Anything that hinders the inspector’s access should be noted in the report.
6.3  Revisits
It is expected that the inspector will perform only one walk-through survey per inspection report.  However, it may be necessary for the inspector to revisit certain areas of the subject building after performing the research portion of the inspection.
6.4  Inspector Safety
It is the responsibility of the inspector to perform the walk-through survey safely.

POOLS & SPA [AN AUXILIARY SERVICE]

Pools and spas do leak, but this may be impossible to confirm without the use of specialized equipment. However, it could become apparent from secondary evidence during the inspection, which is purely visual. Regardless, the owner or the occupant of a property would be aware that the water level drops regularly and must be topped off, and this should be disclosed. Unusually high water bills could reveal this, but only a pressure test of the pipes, a dye test of cracks, or a geo-phone test of specific areas would confirm it, which is beyond InterNACHI standards and disclaimed as a function of the inspection. * Building Supporters offers an auxiliary service as an add-on service which includes leak detection testing, for an additional fee.

A Well Inspection

[AN AUXILIARY SERVICE]

is the visual inspection of the well components (well head, well head cap/seal, well pressure tank, attached plumbing, and the well pump electrical control systems), including a one-hour well pump flow test (although the flow test may be stopped if the well appears to be running dry), performed for a fee. The purpose of a Well Inspection is to discover marginally or low-producing wells or defective well pumps, and to discover and report defects that were visible at the well components.
The Well Inspection and pump flow test are based on the observations made on the date of the inspection, and not a prediction of future conditions. Tests are valid for the subject property on the date of inspection only. Yield, recovery rate, flow rate, static water level, and storage are dependent on the time of year, weather, soil permeability, and other variable conditions. THIS INSPECTION IS NOT A GUARANTEE OF A CONTINUOUS WATER SUPPLY OR THAT THE WELL WILL CONTINUE TO PRODUCE THE YIELD AS TESTED.
A Well Inspection will not reveal every issue that exists or ever could exist, but only those material defects observed on the date of the inspection.
A material defect is a specific issue with a system or component at a residential property that may have a significant, adverse impact on the value of the property, or that poses an unreasonable risk to people. The fact that a system or component is near, at, or beyond the end of its normal, useful life is not, in itself, a material defect.
A Well Inspection report shall identify, in written format, defects within the system and the components defined by these Standards that are both observed and deemed material by the inspector. The inspection report may include additional comments and recommendations. The Well Inspection report will also include the total gallons of water pumped during the well pump flow test and the average (GPM) rate of water flow during the test.
The Well Inspection report will outline and define the items that were inspected and indicate any items that were not inspected, the reason they were not inspected, and general statements of what is commonly included and excluded during the Well Inspection.
2 Limitations, Exceptions & Exclusions

2.1  Additional Limitations:
A Well Inspection is not technically exhaustive.
A Well Inspection will not identify concealed or latent defects.
This Standards of Practice applies to properties with a private residential water well.

2.2 Exclusions:
The inspector is not required to:
perform a multi-hour well pump flow test (although the inspector may offer a multi-hour pump flow test as an option).
measure the well’s static water levels (although the inspector may offer to measure the static water levels with a multi-hour well pump flow test if allowed by the homeowner and the local water/governing jurisdiction).
measure the depth of the well.
review or comment on any portion of the well driller’s log.
estimate the well recovery rate or water storage capabilities.
dig soil or snow to locate a well head or in-ground well room.
inspect any water treatment systems.
inspect any in-ground water storage/cistern systems.
measure the distance from the well head to the septic tank(s) or leach field(s).

measure the well pressure tank air pre-charge;

measure the well pump current draw during the pump flow test;
diagnose any well problems.
shock or super-chlorinate the well.
estimate the age or life expectancy of the well pump or any of the well’s components.
operate any well pump that, in the opinion of the inspector, is unsafe or likely to fail during the well pump flow test.

enter/access any area that may or do anything that may, in the inspector’s opinion, be unsafe or dangerous to him/herself or others, or damage property.
enter crawlspaces, well rooms, or other confined areas that may be unsafe or not readily accessible.
move any personal items or other obstructions, such as, but not limited to: throw rugs, carpeting, wall coverings, boxes, furniture, ceiling tiles, window coverings, equipment, plants, ice, debris, snow, or anything else that might restrict the Well Inspection.

3.0 Standards of Practice
3.1 Well Systems Inspection
The inspector will:
calculate the total gallons of water pumped during the well pump flow test;
calculate the average GPM flow during the well pump flow test;
visually inspect the condition of the well head and surrounding site conditions (if the well head cannot be located, this must be documented in the written report);
measure the height of the well head from grade;
visually inspect the condition of the well head cap or seal;
visually inspect the condition of the visible portions of the well casing;
note approximate location of well head in written report;
visually inspect the condition of the well pressure tank;
visually inspect the condition of the well pressure switch;
visually inspect for the presence of and condition of a well water pressure gauge;
inspect for the presence of and the rating of any installed well pump control panel;
inspect for the presence of a well pump disconnect panel or switch; and
inspect for the presence of a main water shutoff valve.
The inspector shall report as in need of correction:
any well that runs dry during the one-hour well pump flow test;
any well that fails to average at least 3 GPM flow during the well pump flow test;
any well pump whose current draw is higher than the rating listed on the well pump control panel;
any well pump whose current draw fluctuates more than 1 amp during the well pump flow test;
any waterlogged well pressure tank;
any corroded or leaking well pressure tank;
any well head cap/seal that is damaged, loose, or missing;
any well head that does not extend above grade by at least 12 inches; and
any burnt or corroded pints or contacts inside the well pressure switch.

Sewer Inspection

[AN AUXILIARY SERVICE]

 

1. Definitions and Scope

1.1.  A sewer scope inspection is a video inspection of the lateral sewer line (referred to by plumbing codes as the “building sewer”) from the house at or near the foundation to the municipality’s or HOA’s tap or septic tank, performed for a fee.  The purpose of a sewer scope is to discover and report defects that are visible in the lateral sewer line that are both observed and deemed material by the inspector, as defined by these Standards; the scope will typically also identify the material used for the lateral sewer line. The scope of work may be modified by the Client and Inspector prior to the inspection process.

1.2.  A material defect is a specific issue with a system or component of a residential property that may have a significant, adverse impact on the value of the property, or that poses an unreasonable risk to people.  The fact that a system or component is near, at, or beyond the end of its normal, useful life is not, in itself, a material defect.

1.3.  A sewer scope inspection report shall identify, in written format, defects within the system and components defined by these Standards that are both observed and deemed material by the inspector. Inspection reports may include additional comments and recommendations.

The sewer scope inspection report will outline and define the portions of the sewer line that were inspected and indicate any areas that were not inspected, the reason they were not inspected, and general statements of what is commonly included and excluded during the sewer scope inspection.
2. Limitations, Exceptions & Exclusions

2.1.  Limitations

  1. A sewer scope inspection is not technically exhaustive.
  2. A sewer scope inspection will not identify concealed or latent defects.
  3. This Standards of Practice applies to properties with four or fewer residential units.

 

2.2.   Exceptions

  1. The sewer scope inspection is based on the observations made on the date of the inspection, and not a prediction of future conditions.
  2. The sewer scope inspection will not reveal every issue that exists or ever could exist, but only those material defects observed on the date of the inspection.

2.3.  Exclusions

The inspector is not required to:

  1. remove or pull toilets to access the main or lateral sewer line.
  2. move any personal items or other obstructions, such as, but not limited to:  throw rugs, carpeting, wall coverings, boxes, furniture, ceiling tiles, window coverings, equipment, plants, ice, debris, snow, or anything else that might restrict the sewer scope inspection.
  3. climb a roof to access a sewer vent pipe if deemed unsafe by the inspector.
  4. enter or access any area or do anything that may, in the inspector’s opinion, be unsafe or dangerous to him/herself or others, or damage property.
  5. enter crawlspaces or other areas that may be unsafe or not readily accessible.
  6. locate and/or mark any defect observed in the sewer scope video.
  7. provide the length of the main or lateral sewer line to the municipality’s or HOA’s tap or septic tank.
  8. scope or inspect underfloor or in-house portions of the building drain or sewer system.
  9. give correction, replacement or repair cost estimates.

3. Standards of Practice

3.1. Sewer Scope Inspection

1. The sewer scope inspector will inspect and video-record:

  1. the main or exterior lateral sewer line from a proper cleanout or roof vent stack;
  2. record the entire video and provide the video to the client as either an online link or a physical copy;
  3. document any and all defects observed in the video inspection; and
  4. if a cleanout is not visible or accessible, the inspector will note that in the report.

2. When possible, the sewer scope inspector shall describe:

  1. the type of lateral sewer line or pipe materials. Description is not a material identification guarantee and generalized observation.

3. The inspector shall report as in need of correction:

  1. the presence of visible cracks;
  2. the presence of any observed plant or tree root intrusion;
  3. the presence of any offset over 1/2-inch;
  4. the presence of over 1 inch of standing water;
  5. the presence of a blockage or restriction;
  6. the presence of a crushed line or pipe;
  7. the presence of a broken line or pipe;
  8. the presence of a separated or disconnected line or pipe;
  9. the presence of excessive rust or scale;
  10. the presence of an excessive amount of grease;
  11. the presence of deteriorated concrete;
  12. the presence of an egg-shaped line;
  13. the presence of a collapsed line or pipe; and
  14. the presence of delamination or deterioration.

4. The inspector is not required to:

  1. identify the presence of Orangeburg or Bermico (bituminous fiber pipe).
  2. identify the presence of asbestos cement or Transite pipe.
  3. go beyond 200′ line distance or scope entire distance. Inspector has full discretion of length of scope and may cut sewer scope length short at any time, if numerous turns are encountered or line resistance occurs.

2.7 Definitions
2.1 Scope

The purpose of this standard is to provide standardized procedures to be used for a mold inspection.
There are two types of mold inspections described in the IAC2 Mold Inspection Standards of Practice:
1) the Complete Mold Inspection (see Section 2.2); and
2) the Limited Mold Inspection (see Section 2.3).
2.1.1 Unless the inspector and client agree to a limitation of the inspection, the inspection will be
performed at the primary building and attached parking structure. Detached structures shall be
inspected separately.
~ 10 ~
2.1.2 A mold inspection is valid for the date of the inspection and cannot predict future mold growth.
Because conditions conducive to mold growth in a building can vary greatly over time, the results
of a mold inspection (examination and sampling) can be relied upon only for the point in time at
which the inspection was conducted.
2.1.3 A mold inspection is not a home (property) inspection.
2.1.4 A mold inspection is not a comprehensive indoor air-quality inspection.
2.1.5 A mold inspection is not intended to eliminate the uncertainty or the risk of the presence of mold,
or the adverse effects mold may cause to a building or its occupants.

2.5.1 General Comments
• Use the IAC2 Mold Sampling Decision Chart and the IAC2 Standards of Practice to assist in deciding
when and where to take samples in a building.
• Samples of the indoor air and the outside air should be taken for comparison. There should not be
any mold inside the house that is not found outside. The concentration of mold inside a home should
not be higher than the concentration of mold outside.
• Keep in mind that mold spores in the air being sampled can vary greatly in relation to the life cycle of
the mold, atmospheric and environmental conditions, and the amount of ventilation. There is
seasonal and diurnal variability in airborne mold at an indoor, residential environment.
• Air sampling may be necessary if the presence of mold is suspected (if, for example, musty odors
are noted) but cannot be identified by a visual examination. The purpose of such air sampling is
to determine the location and/or extent of mold contamination. All mold spores have a source, and
identifying the source is the goal.
• Because the outdoor sample is the control sample and is used to compare with the indoor sample,
the samples should be collected as close as possible in time and under similar conditions. Air
samples should be collected at the same air-flow rate, for the same duration of time, near the same
height above the floor in all rooms that are sampled indoors, and using the same type of collection
device.
2.5.2 Air-Flow Rate
• There are many different types of air pumps, measurement meters and spore collectors that can be
used for an air sample at a mold inspection. The air pump should be adjusted to collect air at a flow
rate that is recommended by the manufacturer of the collection device. The result of an air-pump
sample is recorded in spores per meter, cubed (spores/m3
).
• If the air-flow rate is too fast, the spores will bounce off the collector plate or slide and will not stick.
If the air-flow rate is too slow, the spores float around the collector plate or slide and will not stick.
2.5.3 Rotameter
• Rotameters are air-flow meters that provide field accuracy in an easy-to-read instrument. The
principle of operation is simple: air flow passes through a vertical, tapered tube and pushes a small
ball or float, having a diameter slightly less than the smaller end of the tube. As the little ball rises,
the clearance between the ball and the tube wall increases. The ball becomes stationary when the
diameter of the tube is large enough to allow the total air flow past the ball. The flow rate is
determined by reading the number on the tube at the middle position of the stabilized ball.
~ 15 ~
2.5.4 Surface Sampling
• Surface sampling can provide information regarding whether the visible, apparent mold is, in fact,
actual microbial growth (mold) or not, can measure the relative degree of the mold contamination,
and can serve to confirm that the sampled mold growth may be producing mold spores in the air.
2.5.4.1 Area of Concern: Take One Sample
• If there is an area of concern (such as a room or area with moisture intrusion, water damage, musty
odors, apparent mold growth, or conditions conducive to mold growth), the inspector shall perform
at least one surface sample in each area of concern.
• Additional surface samples may be performed at the discretion of the inspector.
2.5.4.2 No Areas of Concern: Not Required
• If there are no areas of concern (no moisture intrusion, no water damage, no musty odors, no
apparent mold growth, and no conditions conducive to mold growth), the inspector is not required
to perform a surface sampling.
• Surface samples may be performed in other areas of the building at the discretion of the inspector.
2.5.4.3 Swab
• A swab comes inside a plastic tube container. The cellulose swab is moistened with a liquid
preservative stored in an ampoule at one end of the tube container. Any bacteria collected with
the swab are transferred via the swab into a tube. The tube is sent directly to a laboratory for
analysis.
• A swab provides immediate determination of the presence of fungal spores, as well as the types of
fungi present.
2.5.4.3.1 Areas of Concern
• The inspector shall take at least one swab sample when a visual examination of the building yields
moisture intrusion, water damage, apparent mold growth, musty odors, or conditions conducive to
mold growth. Additional sampling may be performed at the discretion of the inspector.

2.5.4.3.2 Sampling
• In general, an inspector will typically hold the tube container so that the ampoule with the
liquid preservative is at the top. Pinch the plastic tube so the liquid will flow down onto the
swab. To remove the moistened swab, pull on the cap. Rub and roll the wet swab over a
one-inch square area of the apparent mold growth. The swab should collect visible
apparent mold. Insert the swab back into the tube. Secure the cap.
~ 16 ~
2.5.4.3.3 Each Sample
• A unique sample number should be recorded for each swab sample. Write the number on the tube
itself. The Chain-of-Custody document should have the sample number, location, and date and time
of the sampling.
2.5.4.3.4 Each Room
• Take a sampling in each room or area where there is visible, apparent mold.
2.5.4.3.5 Each Color
• If there is apparent mold growth of different colors in the room or area, take a sample of each
different-colored mold. The different colors may indicate different types of mold.
2.5.4.3.6 Each Substrate
• If mold is visible on different substrates or building materials, such as wood, drywall or wallpaper,
then a sample from each different material is recommended.
2.5.4.4 Tape
• A tape system provides a quick way to sample visible mold. A tape-lift system is the most common
surface-sampling technique. It can be used instead of a swab sampling. Many tape samples can
be collected in a short period of time. Samples that show hyphae fragments and reproductive
structures can provide proof of mold growth.
• One of the most popular tape sampling products is the Bio-Tape™ system. There are many
advantages of using tape-lift systems (such as Bio-Tape™) instead of using regular tape.
Bio-Tape™ is easier to handle, the tapes are individually numbered, it requires less laboratory
preparation time, and the slides are flexible and will not break.
• The sampling result is not quantitative. The presence of fungi can be confirmed, genera can be
identified, and possibly a semi-quantitative estimation of the amount of each genus can be
determined.
2.5.4.4.1 Sampling
The procedure to using a tape-lift system such as Bio-Tape™ is as follows:
• remove the slide from the mailer;
• record the sample number and all other identification information prior to taking the sample;
• peel off the protective liner from the slide to expose the adhesive;
• place the slide with the sticky side down onto the contaminated area being sampled;
• press down gently and make contact (excessive pressure is not necessary);
• lift the slide from the surface and place it back into the slide mailer. Do not replace the protective
liner;
• record all information on the Chain-of-Custody document, including property address, date, time and
sample number; and
• mail the sample to the laboratory.
~ 17 ~
2.5.4.4.2 PPE
• Because there is direct contact with and disturbance of the contaminated area, PPE is recommended,
including gloves and a respirator rated at N-95 or higher.
2.5.4.4.3 Each Sample
• A unique sample number should be recorded for each tape sample. The Chain-of-Custody document
should have the sample number, location, and date and time of the tape sampling.
2.5.4.4.4 Each Room
• Take a tape sampling in each room or area where there is visible, apparent mold.
2.5.4.4.5 Each Color
• If there is apparent mold growth of different colors in the room or area, take a tape sample of
each sample of each different-colored mold. The different colors may indicate different types of mold.
2.5.4.4.6 Each Substrate
• If mold is visible on different substrates or building materials, such as wood, drywall or wallpaper,
then a tape sample from each different material is recommended.
2.5.4.5 Carpet
• A carpet tends to contain the history of any mold that has been growing in the building. The carpet
sampling is performed to reveal previous mold problems. A carpet sampling can also reveal
undetected mold growth that may have been covered over or cleaned up. Choose an area that is
not heavily walked upon — an area with little foot traffic. Do not sample under furniture.
• A household vacuum cleaner and a carpet-sampling cartridge are used to vacuum a small area of
the carpet. The cartridge should be inserted as deep into the pile of the carpet as possible. If a carpet
has not been cleaned thoroughly prior to a sampling, a carpet can easily hold evidence of a mold
problem in the house. Even after cleaning, there can be mold spores discovered deep in the carpet.
2.5.4.5.1 Set-Up
• Insert the nylon filter into the collector nozzle. It should snap into place. Attach the device to the
vacuum hose securely. An adapter may be needed. If the attachment is loose, use duct tape to
make a tight connection.
2.5.4.5.2 Sampling
• Choose a 6-foot by 3-foot sampling area in front of a sofa or large chair where occupants spend a
lot of time. Vacuum this area thoroughly. Next, select a 6-foot by 3-foot area in a bedroom
alongside a bed. Remove the filter and place it into the bag that came with the unit.
Mail it to the laboratory.
2.5.5 Outdoor Air Sampling
2.5.5.1 Two Outdoor Samples
• The inspector shall perform two outdoor samples of the highest-quality general air to be used as
control samples (or background samples). These samples are to be used for comparison with the
indoor sample(s).
~ 18 ~
2.5.5.2 Upon Arrival
• The outdoor sampling should begin soon after arriving at the property, assuming that the weather
is clear and calm. It is better for an inspector to perform the outdoor sampling while the weather
is favorable than to wait. The outdoor conditions may change drastically during the examination
and sampling of the building’s interior.
2.5.5.3 Weather
• Air sampling should not be conducted during unusually severe storms or periods of unusually high
winds. Severe weather will affect the sampling and analysis results in several ways.
• First, a high wind will increase the variability of airborne mold-spore concentration because of
wind-induced differences in air pressure between the building’s interior and exterior. Second,
rapid changes in barometric pressure increase the chance of a large difference in the interior and
exterior air pressures, consequently changing the rate of airborne mold spores being sucked into
the building. Weather predictions available on local news stations can provide sufficient information
to determine if these conditions are likely.
2. 5.5.3.1 Clear and Calm
• On a Chain-of-Custody form, the weather conditions shall be recorded. The weather conditions should
be clear and calm. High winds may affect the quality of the sampling, including the comparison
between indoor and outdoor samplings.
2.5.5.3.2 No Rain
• An air-pump sampling should not take place outdoors if it is raining. If possible, wait at least two
hours after the rain has stopped before taking an air-pump sample. Alterations or adjustments to the
normal procedure or locations of taking air-pump samples, particularly for the control sample, must
be recorded in a Chain-of-Custody form.
2.5.5.3.3 Above Freezing
• An air-pump sampling should not take place when the outdoor air temperature is below 32° F. All
air sampling should take place when the air temperature is above freezing.
2.5.5.3.4 No Snow Covering
• If the ground is completely covered with snow, outdoor air-pump sampling should not be performed.
A partial covering or a light dusting of snow is acceptable.
2.5.5.3.5 Ten Minutes
• On a clear, windless day, air-pump sampling should run for 10 minutes. (Be sure to refer to the
manufacturer’s recommendation.) When the outdoor air is not clear and windless, then the time of
the sampling should be reduced to five minutes or less. A breeze, the mowing of grass, nearby
construction, and dusty air can all affect the sampling conditions.

~ 19 ~
2.5.5.4 Location
• If possible, one outdoor sample should be located on the windward side of the building (the side facing
the point from which the wind blows), and the other should be located on the leeward-side of the
building (the side sheltered from the wind).
• The sampling device located on the windward side of the building should be positioned so as to face
the wind directly. The sampling device should point toward the wind, in the direction of the point
from which the wind is blowing. The sampling device should be 3 to 6 feet from the ground surface
(breathable space).
• Typically, the device should be about 10 feet away from the front entry door. The idea is to have both
outdoor samples located in areas where the devices will collect a representative sampling of the air
that may enter the building through the entry door or nearby open windows (the openings on the
sides of the building).
2.5.5.4.1 Ten Feet
• If there is a main ventilation component of the building that draws fresh air into the building from
the outdoors, the sampling should be performed 10 feet from that intake.
• The sampling should be performed at least 10 feet from the most frequently used entrance to the
home.
• The air sampling devices should be kept at least 10 feet away from all openings, air intakes, registers,
exhaust vents, vent pipes, ventilation fans, etc.
2.5.5.4.2 Nothing Overhead
• Sampling should not be performed under an overhang, soffit or eave, or carport, porch roof, or any
other roof or overhead structure.

2.5.6 Indoor Air Sampling
2.5.6.1 Closed-Building Conditions
• Indoor air sampling should be made under closed-building conditions. Closed-building conditions are
necessary in order to stabilize the air that may contain mold spores or mVOCs, and to increase the
reproducibility of the air sampling and measurement.
• Windows on all levels, as well as external doors, should be kept closed (except during normal entry
and exit) during the sampling period. Normal entry and exit include a brief opening and closing of
a door, but–to the extent possible–external doors should not be left open for more than a few
minutes.
• In addition, external-internal air exchange systems (other than a furnace), such as high-volume,
whole-house and window fans should not be operating. However, attic fans intended to control
attic (and not whole-building) temperature and humidity should continue to operate. Combustion
or make-up air supplies must not be closed.
~ 20 ~
• Normal operation of permanently installed energy-recovery ventilators (also known as heat-recovery
ventilators or air-to-air heat exchangers) may also continue during closed-building conditions. In
houses where permanent radon mitigation systems have been installed, these systems should be
functioning during the air-sampling period.
• Closed-building conditions will generally exist as normal living conditions in northern areas of the
country when the average daily temperature is low enough so that windows are kept closed.
Depending on the geographical area, this can be the period from late fall to early spring.
2.5.6.2 HVAC
2.5.6.2.1 Take One Air Sample
• At least one air sample shall be taken at an air-supply register of the HVAC system. It is preferred to
sample prior and during the operation of the HVAC system. If only one sampling can be performed,
then the sampling should be taken 15 minutes after the HVAC system is turned on.
• Ideally, there would be at least three sampling devices similarly situated throughout the building, but
financial or time constraints may limit the number of samples that can be taken.
2.5.6.2.2 Location
• The air sample should be taken 3 to 5 feet from an air-supply register, with the sampling device
oriented so that air from the supply register directly enters the sampling device.
2.5.6.2.3 Agitation
• A gentle or vigorous mechanical agitation of the ductwork (a bump or shake) is appropriate.
2.5.6.3 Indoor Air
2.5.6.3.1 Take One Air Sample
• The inspector shall perform at least one indoor sampling. Additional samplings may be performed at
the discretion of the inspector.
2.5.6.3.2 Areas of Concern
• At least one air sample shall be taken near the center of each room or area of the building in which
there are areas of concern (moisture intrusion, water damage, musty odors, visible, apparent mold
growth, and/or conditions conducive to mold growth).
2.5.6.3.3 No Areas of Concern
• At least one indoor air sample shall be taken in the most lived-in common room, such as the family
room or living room. (The location shall be determined at the discretion of the inspector.)
2.5.6.3.4 Location
• An indoor air sampling should only take place in a livable space in the building. Sampling in areas
such as closets, under-floor crawlspaces, unfinished attics, storage or utility rooms, or inside the
HVAC system is prohibited.
~ 21 ~
• The indoor air sample should be taken in the middle or center area of the area or room.
• The air collection device should be placed about 3 to 6 feet above the floor’s surface.
2.5.6.3.5 Ten Minutes
• Inside the building, the air-pump sampling should run for 10 minutes. If there is a lot of indoor
activity, then the air-pump sampling should be reduced to five minutes. If there is an active source
of dust, such as construction or cleaning, then the air sampling time should be reduced to one minute.
Be sure to follow the recommendations of the manufacturer of the sampling device or collector.
2.5.6.4 Sampling
• The sampling equipment must be protected, clean and properly maintained at all times. The sampling
device shall be clean and free from dirt or debris prior to starting a sampling. If re-usable collection
devices are used, then they shall be handled and cleaned prior to use, in accordance with the
manufacturer’s recommendation. The collector may be re-useable and have sticky slides already
prepared, or the collector may be a one-time-use, self-contained device.
• Slides, cassettes, and one-time-use devices should be stored in cool, dry environments. The slides
must be protected from direct sunlight. Sampling devices (slides, swabs, cassettes, tapes) older than
one year should not be used.
• Set the air collector at a normal breathing height, which is about 3 to 6 feet above ground level or the
floor’s surface. A tripod is typically used to set the collector’s height.
• Calibrate the flow of the pump. Do not attach the sampling device, cassette or collector on the tubing
yet. Measure the flow rate of the pump with a rotameter that has been calibrated to a standard.
Make sure that the flow rate is set to the manufacturer’s recommendation. For example, an Air-O-Cell
cassette flow rate is 15 liters of air per minute. The pump should be calibrated regularly (once a
day). A record of calibrations should be kept in a work ledger or log book.
• After calibration, securely attach the tubing of the pump to the sampling device or collector. Turn on
the pump. Start sampling. Record the start time.
• After turning on the air pump, check the air-flow rate. The flow rate should not vary. A flow change
greater than 5% requires a new air sample to be taken. All air samples must have the same volume.
A digital time controller on the equipment is highly recommended.
• Examine the collector. There should not be an overload on the slide. There should be a fine trace,
hardly visible to the human eye, of dust and spores on the slide. A slide that has an easily visible
trace on it may be unreadable. If that is the case, the environmental conditions may need
improvement or a new sampling location may be needed. If a slide is heavy, a new sample should
be taken.
• Remember, all air samples must have the same volume. Refer to the manufacturer’s
recommendations about sampling time and volume for each type of sampling device.
• Record the time that the pump stopped. Mark the sampling device with a unique sampling number.
Record that information on the Chain-of-Custody form.
~ 22 ~
• Place slides in a protective carrying case, or close the collector if a cassette is used. A new sample
must be taken if a slide is accidentally touched, smeared or contaminated because it will be
unreadable.
• Calculate the volume by multiplying the liters of air pumped by the number of minutes. An example
of the calculation is 20 liters of air pump multiplied by 10 minutes equals 20 liters per minute or
200 liters (20L x 10 minutes = 200 L).
