Codes, Standards, and Inspection Methodology
This domain tests how codes and standards differ, how they apply to an inspection, and how to state scope so a report does not become a code certification.
Code versus standard
A code is a legal requirement adopted by a jurisdiction, often a model code with local amendments. A standard is a consensus document such as ASTM E2018, NFPA 101, or the 2010 ADA Standards that may be referenced by code or by contract. The applicable edition is the one adopted locally, not necessarily the newest.
Inspector's role
A baseline PCA observes and reports; it does not certify code compliance, design repairs, or determine occupancy. If the client wants a code review, define the code, edition, and scope in the agreement. Use "appears" and "consistent with" language; refer determinations to the authority having jurisdiction.
Worked example
A 1985 warehouse has a newer tenant improvement with a 6-foot corridor and no sprinklers. The client asks, "Is it code compliant?" Reasoning: the answer depends on the adopted code edition, the occupancy, and whether the tenant improvement was permitted. You can report the observed corridor width and lack of sprinklers, note that code compliance is outside baseline scope, and recommend review by the AHJ and a code consultant. Do not cite a current model code as retroactive.
Traps
Quoting code sections without edition or amendments; assuming current code applies to existing buildings; confusing ADA with local accessibility rules; and using "code compliant" in a report.
