AHI Code of Ethics
The following rules of conduct and ethics help maintain integrity and
objectivity within the home inspection profession. In any instance where the
AHI Code of Ethics and the law conflict, the obligations of the law shall
take precedence.
I. PROFESSIONAL CONDUCT
The home inspector shall
- Always act in good faith when dealing with a client.
- Not disclose the results of a home inspection to any other party
without client approval. - Not express an opinion unless it is based on fact, education, or
experience. - Not accept compensation from more than one interested party for the
same service without the consent of all interested parties. - Not accept commissions or allowances from other parties involved
with the real estate transaction. - Maintain truth in advertising, marketing, and promotion of services or
qualifications. - Not advise a client whether or not to buy a property after the home
inspection. - Immediately disclose any observed immediate safety hazards to
occupants exposed to such hazards. - Comply with any inquiry or compliance requirement by a home
inspector regulatory body. - Not aid or assist another in the violation of this Code of Ethics.
II. THE INSPECTION AND REPORT
The home inspector shall - Perform an inspection that is substantially in compliance with the AHI
Standards of Practice. - Enter into a written agreement with the client prior to the inspection
that includes the scope of the home inspection, listing the components
and systems to be inspected along with limitations and exclusions. - Inspect all items that fall within the scope of the home inspection
- Submit a written report to the client within 1-2 business days that
a. describes inspected systems and components;
b. reports any items deemed significantly deficient;
c. states why items were deemed significantly deficient;
d. discloses items within the scope that were not inspected and the reason.
III. DISCLOSURE OF A CONFLICT OF INTEREST
The home inspector shall - Prior to the inspection, disclose in writing to the client any personal
interests that may affect the client; - Not allow any personal interest to affect the quality of the results of a
home inspection; - Provide additional services to the client only after securing the written
consent of the client in a separate agreement that includes a written
statement of the services intended and how such additional services
may conflict with the home inspection services provided.
Standards of Practice:
I)The Home Inspection: is based on the observations made on the date of the
inspection, and not a prediction of future conditions.
II. The home 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 home 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.
2) Limitations, Exceptions & Exclusions
2.1. Limitations:
I. An inspection is not technically exhaustive.
II. An inspection will not identify concealed or latent defects, “vices cachees”
III. An inspection will not deal with aesthetic concerns, or what could be deemed
matters of taste, cosmetic defects, etc.
IV. An inspection will not determine the suitability of the property for any use.
V. An inspection does not determine the market value of the property or its
marketability.
VI. An inspection does not determine the insurability of the property.
VII. An inspection does not determine the advisability or inadvisability of the
purchase of the inspected property.
VIII. An inspection does not determine the life expectancy of the property or any
components or systems therein.
IX. An inspection does not include items not permanently installed.
X. This Standards of Practice applies to properties with four or fewer residential
units and their attached garages and carports.
2.2. Exclusions:
I. The inspector is not required to determine:
A. property boundary lines or encroachments.
B. the condition of any component or system that is not readily accessible.
C. the service life expectancy of any component or system.
D. the size, capacity, BTU, performance or efficiency of any component or
system.
E. the cause or reason of any condition.
F. the cause for the need of correction, repair or replacement of any system or
component.

coverings, equipment, plants, ice, debris, snow, water, dirt, pets, or anything
else that might restrict the visual inspection.
B. dismantle, open or uncover any system or component.
C. enter or access any area that may, in the inspector’s opinion, be unsafe.
D. enter crawlspaces or other areas that may be unsafe or not readily accessible.
E. inspect underground items, such as, but not limited to: lawn-irrigation
