Can the authority having jurisdiction require special inspectors or final reports?

Last reviewed: July 6, 2026

What the code requires — plain English (controlling §)

The designated controlling section §1405.3 was not found in the uploaded California Mechanical Code material, so I cannot quote or ground requirements directly to §1405.3. I state that plainly here.
Absent text for §1405.3, the applicable, retrievable rules are: the Authority Having Jurisdiction (AHJ) has broad administrative powers to require inspections, submittals and documentation under the Mechanical Code (see §103.1 and §103.3) and the California Building Code sets explicit rules for when special inspectors and written final reports are required and who they must be submitted to (see §1704.2.4).

The AHJ may require special inspectors and final reports where the AHJ determines they are necessary to verify code compliance — the Building Code’s special-inspection/report rules are the operative place to look for the required content and recipients of those reports.

(First occurrences: §1405.3, Authority Having Jurisdiction, special inspectors, final report are shown bold above.)

Requirements in detail

1) Can the AHJ require special inspectors?

Yes. The Mechanical Code authorizes the AHJ to adopt rules, require plans and information and to appoint inspectors — that administrative authority supports requiring additional inspections where needed (see §103.1 and §103.3).
The California Green Building Standards Code explicitly contemplates that the enforcing agency (AHJ) can require the owner to employ special inspectors when needed for compliance; it also addresses special-inspector qualifications and independence. See §702.2.

2) What about requiring written reports or a final report?

The California Building Code requires approved agencies / special inspectors to keep records and to submit reports of special inspections and tests to the building official at frequencies required by the approved construction documents or the building official. A final report documenting the required special inspections/tests and correction of any discrepancies must be submitted at an agreed time prior to the start of work or as required by the building official. See §1704.2.4.

3) Who must receive the reports?

Reports must be submitted to the building official (the AHJ’s representative) and to the registered design professional in responsible charge, per §1704.2.4. The AHJ may set frequency and timing.

4) Qualifications and independence

Special inspectors must demonstrate competence acceptable to the enforcing agency; the Green Code lists example certifications and requires independence (no financial interest in the materials or the project). See §702.2.

Decision-relevant dimensions (quick reference)

Decision question	Values / who does it	Required documentation	Code reference
May AHJ require special inspectors?	Yes, where AHJ deems necessary	Name/qualifications of inspector; statement of special inspections (where applicable)	§103.1, §103.3, §702.2
Must special-inspection reports be filed?	Yes — periodic and final as required	Inspection/test reports describing nature/extent and conformance; final report documenting corrections	§1704.2.4
Who receives reports?	Building official and registered design professional	Copies of inspection/test reports; final verified report	§1704.2.4
Are special-inspector qualifications required?	Yes — competence acceptable to enforcing agency	Written documentation of competence, certifications as applicable	§1704.2.1, §702.2
Exceptions (minor work)	AHJ may waive for minor work	AHJ-approved exceptions	§1704 exceptions

(Where the Mechanical Code text for §1405.3 is unavailable in the provided files, the above is grounded in the Code sections that are present in the uploaded materials.)

Exceptions & special cases

The Building Code provides exceptions to special-inspection requirements: the building official (AHJ) may determine special inspections are not required for work of a minor nature or for certain accessory Group U occupancies, among other exceptions. See the exceptions to Section 1704.
The Green Code notes that qualifications and the precise triggers for special inspection are subject to the enforcing agency’s determination (so local adoption and checklists matter). See §702.2.
Boiler/pressure‑vessel programs in the Mechanical Code delegate certain inspection/reporting regimes (operating permits, periodic inspections, and approved company inspectors under AHJ approval). For program-specific reporting/inspection steps see the boilers/pressure-vessel sections in the CMC (see the operating-permit and inspection subsections).

Note: I could not find §1405.3 text in the uploaded files; if §1405.3 contains more specific or different rules, please upload that page or allow me to look it up so I can cite it directly.

Common mistakes

Assuming the AHJ can never require third‑party special inspectors. In fact, the AHJ can require them where necessary to verify compliance; the AHJ also sets qualifications and submission timing. See §103.1 and §1704.2.4.
Treating “special inspection” as identical across codes — the Building Code (Chapter 17) is the primary rulebook for special inspections; CALGreen adds green-specific inspector expectations. Don’t rely solely on general Mechanical Code administration text. See §1704.2.4 and §702.2.
Forgetting to send the final report to both the building official and the registered design professional — the Building Code requires both recipients. See §1704.2.4.

Worked example — concrete scenario

Scenario: A developer is installing a multi‑zone HVAC system that the AHJ determines affects life-safety smoke-control functions and asks for continuous special inspection and a final verified report.

AHJ action: Cites administrative authority to require additional inspections and specifies that an approved special-inspection agency do continuous observation of the critical ductwork and smoke-control dampers. Authority for requiring inspections comes from §103.1 / §103.3 (AHJ powers).
Owner responsibility: Owner hires an approved agency whose inspectors meet competence criteria. The owner submits the inspector qualifications to the AHJ before work starts (per special‑inspector qualification practice in §1704.2.1 and §702.2).
Reporting frequency & content (example numbers): AHJ requires weekly written progress reports and daily verified logs for the smoke-control sequences during commissioning; the final report must be a verified document certifying that required inspections/tests were done, listing discrepancies and confirming corrections. These reporting requirements are consistent with the Building Code’s rule that approved agencies shall submit reports at frequencies required by the approved construction documents or building official and that a final report be submitted documenting required special inspections and corrections. See §1704.2.4.
Outcome: The AHJ will not release the final approval/occupancy sign‑off until the final verified report is received and accepted by the building official. This requirement follows the report/final-report practice in §1704.2.4.

Related provisions — quick list

California Mechanical Code: §103.1 — Duties and powers of the Authority Having Jurisdiction (administrative authority to require information/inspections).
California Mechanical Code: §103.3 — Applications and permits; AHJ may require submission of plans, specifications and other information.
California Mechanical Code (boilers): §1013.2 — Operating permits and that equipment must be inspected and approved by the AHJ before operation (see boiler/pressure-vessel inspection program).
California Building Code: §1704.2.4 — Approved agencies shall keep records and submit reports of special inspections and tests; final report requirements.
California Building Code: §1704.2.1 — Special inspector qualifications and required documentation to the building official.
California Green Building Standards Code: §702.2 — Special inspection when required by enforcing agency; qualifications and independence of special inspectors.

If you want, I can:
