When must documents be prepared by a registered design professional?

In California the CBC requires construction documents to be prepared by a registered design professional only when statutes of the jurisdiction require it; the building official can require additional RDP-prepared documents for special conditions or waive submittals where review isn’t needed, and when RDP preparation is required the owner may have to designate an RDP in responsible charge to coordinate plans and deferred submittals (see § 107.1 and related provisions).

What the code requires — 2–4 sentences

The California Building Code requires that construction submittal documents (construction documents, statement of special inspections, geotechnical report and other data) be prepared by a registered design professional (RDP) when such preparation is required by the statutes of the jurisdiction where the project is to be built — i.e., when law or the local authority requires it. The building official may also require additional documents to be prepared by an RDP where special conditions exist, and the official may waive submittals not required to be prepared by an RDP if review is unnecessary. See § 107.1 for these rules.

Requirements in detail

Trigger: “Where required by the statutes of the jurisdiction”

What the rule says: Construction documents must be prepared by a registered design professional where required by statute (state or local law). That is the primary trigger — the CBC defers to the law that applies in the jurisdiction for which the permit is sought. § 107.1.

Building official discretion: additional requirements or waivers

The building official is explicitly authorized to require additional construction documents to be prepared by an RDP where special conditions exist. Conversely, the building official may waive submission of documents not required to be prepared by an RDP if the work’s nature makes review unnecessary. § 107.1 (including the Exception).

Decision-relevant dimensions (quick reference table)

Decision dimension	Values / what to check	Code reference
Who must prepare construction documents?	Registered design professional — when statutes of the jurisdiction require it	§ 107.1
Who can require additional RDP documents?	Building official (for special conditions)	§ 107.1
Can submittal requirement be waived?	Yes — building official may waive non‑RDP-prepared submittals if review unnecessary	§ 107.1 (Exception)
Design professional in responsible charge	Owner may be required to designate an RDP in responsible charge on permit application; that RDP coordinates and reviews others’ submittals	§ 107.3.4
Deferred submittals	Deferred items permitted only with prior approval; RDP in responsible charge must list and later review/forward deferred submittals	§ 107.3.4.1
Statement of special inspections	Where special inspections are required, the statement is to be prepared by the RDP in general responsible charge (unless building official permits otherwise)	§§ 1704 and 107.1 cross-reference

Exceptions & special cases

Jurisdictional statutes control: The CBC does not itself list an exhaustive catalog of project types that always require an RDP; instead it requires RDP preparation where statutes of the jurisdiction require it. In other words, local/state law and any agency-adopted rules determine many of the “must” cases — § 107.1.
Building official waiver: If the building official finds a particular project does not require construction document review to determine compliance, the official may waive submittals that would not otherwise be required to be prepared by an RDP. (Exception to § 107.1).
Special inspections / statements: When special inspections or tests are required (see Section 1704), the CBC expects the statement of special inspections to be prepared by the RDP in responsible charge; an exception allows the building official to approve a qualified person to prepare it when the work was not designed by an RDP. §§ 1704.2.3 / 1704.3 (and cross-reference to § 107.1).
Deferred submittals: Deferred submittal items must have prior approval; the RDP in responsible charge must list them and later review and forward deferred documents indicating general conformance. § 107.3.4.1.

Common mistakes

Treating § 107.1 as a blanket requirement that every set of plans must be prepared by an RDP. The CBC requires RDP preparation only where statutes require it; local codes and state law can expand or limit that requirement. § 107.1.
Failing to designate an RDP in responsible charge when the permit requires one. If documents must be prepared by an RDP, the building official may require the owner to designate that professional on the permit application (and to notify the official if the RDP changes). § 107.3.4.
Forgetting to list deferred submittals on the construction documents and not obtaining prior approval for deferrals — deferred items cannot be installed until they are approved. § 107.3.4.1.
Omitting required supporting reports (for example, geotechnical reports or a statement of special inspections) when statutes or other CBC sections require them; many of those reports are explicitly expected to be prepared by an RDP. § 107.1 and Section 1704.
Assuming the building official has no discretion — in fact the official has explicit authority both to require additional RDP-prepared documents for special conditions and to waive certain submittals. § 107.1.

Worked example — mixed-use building (concrete framing, 3 stories)

Scenario:

Owner proposes a three-story mixed-use building with commercial at ground level and two residential floors above. Local ordinance and state law require structural design documents prepared by a licensed structural engineer for buildings of this size/type.

Steps applying CBC requirements:

Because statute/jurisdiction requires it, the structural, architectural and related construction documents must be prepared by the appropriate registered design professionals (architect and structural engineer). (Trigger: § 107.1.)
The permit application includes two sets (or digital sets where allowed) of construction documents, a geotechnical report prepared by a registered geotechnical engineer, and a statement of special inspections prepared by the RDP in general responsible charge if special inspections are triggered (e.g., for concrete). (§ 107.1; cross-reference § 1704.)
The building official requires the owner to designate a registered design professional in responsible charge on the permit application; that person lists any deferred submittals (for example, fire sprinkler shop drawings or glazing shop drawings) on the construction documents. (§ 107.3.4 and § 107.3.4.1.)
The RDP in responsible charge receives deferred submittal documents later, reviews them for general conformance, and forwards them to the building official with a notation of review prior to installation. (§ 107.3.4.1.)
Upon permit issuance, the building official stamps a reviewed set of construction documents and retains one set; the applicant keeps the other set at the job site. (§ 107.3.1, § 107.5.)

Numeric example notes:

Two or more sets (or digital format where allowed) — submit at least 2 sets unless the building official allows digital only. (§ 107.1.)
If concrete special inspections are required (per Section 1705), the statement of special inspections prepared by the RDP will identify which inspections are continuous vs. periodic. (§ 1704 / 1705 cross‑references.)

O PERFORMANCE-BASED APPLICATION

The provisions contained in this appendix are not mandatory unless specifically adopted by a state agency or referenced in the adopting ordinance.

User notes:

About this appendix: Appendix O provides an optional design, review and approval framework for use by the building official. Typical uses would include cases of alternate methods in Chapter 1, select areas of the code that require a rational analysis such as Section 909 and elsewhere. It simply extracts the relevant administrative provisions from the ICC Performance Code into a more concise, usable appendix format for a jurisdiction confronted with such a need. Currently there are multiple, varying jurisdictional rules and procedures in many communities regarding procedure and none in even more. The building official is often left alone to reach decisions not just on the merits of a design but must first also decide on the submittal and review process. As an appendix, the provisions herein are entirely optional to a jurisdiction. This appendix can be adopted, adopted with local modifications, or even used on a case-by-case basis as part of a Memorandum of Understanding or similar legal agreement between the jurisdiction and the owner/design team. It simply represents another tool for the jurisdiction to reach for in cases of need; it neither encourages nor creates any additional opportunity for performance-based design.

ICC code development note: Code change proposals to this appendix will be considered by the Administrative Code Development Committee during the

2025 (Group B) Code Development Cycle.

Frequently asked questions

Who decides whether my project requires documents prepared by an RDP?

The applicable statutes of the jurisdiction control whether an RDP is required; the CBC (§ 107.1) defers to those laws and also gives the building official authority to require additional RDP-prepared documents for special conditions.

Can the building official waive submission of RDP-prepared documents?

Yes — the building official may waive submission of construction documents and other data not required to be prepared by an RDP if the official finds that review of those documents is unnecessary to obtain compliance with the code (Exception to § 107.1).

If documents must be prepared by an RDP, must the owner name an RDP on the permit?

Yes — where documents must be prepared by an RDP, the building official may require the owner to designate a registered design professional in responsible charge on the permit application; that professional coordinates and reviews submittals. § 107.3.4.

Who prepares the statement of special inspections?

When special inspections are required, the statement of special inspections is generally prepared by the registered design professional in general responsible charge, unless the building official permits preparation by a qualified person for work not designed by an RDP (§ 1704.2.3 / § 1704.3).

Are deferred submittals allowed if an RDP prepared the base documents?

Yes, but deferral requires prior building official approval; deferred items must be listed on the construction documents by the RDP in responsible charge and later reviewed and forwarded to the building official before installation. § 107.3.4.1.
