Standards of Practice, Ethics, Report Writing, and Credential Application Procedures

Why Standards of Practice and Ethics Matter

Every inspector credential you are working toward — the InterNACHI CPI, the ASHI ACI, and your state license — rests on two pillars: a Standards of Practice (SOP) and a Code of Ethics. The SOP defines what an inspector is required to inspect, what they are permitted to exclude, and how findings must be reported. The Code of Ethics defines the professional behavior expected before, during, and after every inspection. Exam writers draw directly from these documents, so reading them carefully is not optional — it is your primary study strategy.

InterNACHI Standards of Practice: Key Concepts

The InterNACHI SOP covers the major systems of a residential property: roofing, exterior, basement and crawlspace, heating, cooling, plumbing, electrical, fireplace, attic and insulation, doors and windows, and interior. For each system the SOP specifies what the inspector shall inspect (required actions), what the inspector shall describe in the report, and what the inspector is not required to inspect (exclusions).

Pay close attention to the word "shall." In standards language, shall is mandatory — it creates a duty. The word should recommends but does not require. Exam questions are often written around this distinction. For example, an inspector is required to report observed deficiencies; whether to advise the client on repair contractors is a separate matter governed by ethics, not the SOP.

The InterNACHI Code of Ethics prohibits inspectors from accepting compensation that could compromise objectivity, from inspecting properties in which they have a financial interest without prior disclosure, and from performing repairs on properties they have inspected for compensation within a defined period. Know these prohibitions and their exceptions.

ASHI Standards of Practice: Key Concepts

The ASHI SOP covers similar systems but uses its own specific wording and scope definitions. Like InterNACHI, ASHI distinguishes required inspection items from items that are beyond the scope of a standard home inspection. ASHI also uses shall for mandatory actions. One common exam trap: both SOPs have exclusions for items that are concealed, not accessible, or not permanently installed — but the exact list of excluded items can differ between the two organizations. Annotate both documents side by side so you know where they agree and where they diverge.

The ASHI Code of Ethics addresses conflicts of interest, confidentiality of client information, and the obligation to report all observed conditions honestly. A key principle common to both codes: the inspector's primary obligation is to the client, not to the real estate agent, the seller, or any other party who may have arranged the inspection.

Report Writing Requirements

Both the InterNACHI and ASHI SOPs require that inspection findings be delivered in a written report. A compliant report must:

• Describe the scope of the inspection (what was and was not inspected, and why).
• Identify deficiencies observed, using clear, non-technical language where possible.
• Distinguish between conditions that are safety hazards, conditions that require immediate repair, and conditions to monitor over time.
• Avoid speculative statements about conditions that were not observed.

Report writing is also tested on state licensing exams. Many states reference a specific SOP — often InterNACHI's or ASHI's, or an adopted state version — so confirm which SOP your state recognizes. Reports must be delivered to the client in writing; verbal-only reports do not satisfy the requirement.

Safety note: When documenting hazardous conditions — unsafe electrical panels, structural deficiencies, potential gas leaks, or signs of biological hazards such as mold — your report language must be unambiguous. Under-reporting a safety hazard exposes both the client and the inspector to serious harm and legal liability.

Conflicts of Interest and Ethics Scenarios

Ethics questions on exams almost always involve a conflict of interest or a confidentiality issue. Common scenarios include:

• A real estate agent asks the inspector to "go easy" on the report because the deal may fall through.
• An inspector is asked to inspect a property they own or have a financial stake in.
• A previous inspection client asks the inspector to recommend a specific contractor.
• An inspector discovers a deficiency after the report is delivered — what are the obligations?

In each scenario, return to the relevant Code of Ethics and identify the specific prohibition or duty. The correct exam answer will be the one that protects client interests, maintains objectivity, and avoids undisclosed conflicts.

Assembling Your Credential Application Package

Each credential has its own application process, and errors or missing documents cause delays. Use the following checklist approach:

1. Training hours documentation — your program's official transcript or certificate showing total hours completed.

2. Practice inspection log — the required number of inspections, signed and dated, in the format each organization specifies. Confirm the minimum number directly with InterNACHI and ASHI, as requirements can change.

3. State licensing candidate handbook checklist — completed item by item, with supporting documents attached for each item.

4. Completed application form — verify every field is filled in, signatures are present, and fees are calculated correctly before submission.

5. Background check authorization — most state boards and both credentialing bodies require this.

Have your instructor initial your folder before you submit anything. A rejected application wastes time and may delay your ability to work legally.

Preparing for Exam Day

Practice questions are most valuable when you debrief every wrong answer by locating the exact language in the SOP or Code of Ethics that makes the correct answer correct. Memorizing answer choices without understanding the underlying rule will not serve you on an exam with new scenario wording. Read actively, annotate your documents, and treat each practice question as a direct reference exercise.
