CWUIC · California Wildland-Urban Interface Code

What must construction documents include and what are approvals/phased submittals?

Homeowner summary: For work in the Wildland‑Urban Interface you must submit clear, scaled construction documents (usually two sets or digital) that show what you are building and how it meets WUI rules; the authority keeps one approved set and you must keep one on site for the job, and partial (phased) permits like a foundation permit are allowed but only cover the portion submitted and are issued at your risk.

What the code requires — 2–4 sentences

Construction documents submitted for work in the California Wildland‑Urban Interface Code area must be complete, drawn to scale, and provided in the number and level of detail the code official requires; they must show the location, nature and extent of the proposed work so the code official can verify code compliance. See § 106, § 106.1, and § 106.8 for the core rules and record‑keeping/retention requirements.

Submit clear, complete construction documents (prepared by the required registered professionals), provide required site/vicinity detail for the WUI, and keep one approved set on site while one approved set is retained by the authority.

Requirements in detail

Submittals: what and how

  • You must submit construction documents and supporting data in two or more sets (or digital where allowed) with each permit application; documents must be prepared by a registered design professional where statutes require it. § 106.1 explains submittal format and the RDP requirement.
  • Construction documents must be drawn to scale, on suitable media, and be of sufficient clarity to indicate the location, nature and extent of the work so the code official can determine compliance. This is the core requirement in § 106.
  • CWUIC requires WUI‑specific substantiation when requested (for example, fuel‑loading classification and related data) under § 106.6, and a vicinity plan showing conditions within 300 feet of lot lines under § 106.7.

Approval, retention and on‑site documents

  • One set of approved plans/specifications is to be retained by the code official and another approved set is to be returned to and kept on the job site while work is in progress; retention time is not less than 180 days from completion (or as required by state/local law) per § 106.8.
  • The code official examines the submittal documents to determine conformity with the CWUIC and related laws; changes during construction that deviate from approved documents must be resubmitted as amended documents. See § 106.9 and § 106.10.

Phased approvals (what they are and limits)

  • The code official may issue a phased approval/permit (also called phased approval or permit for part of the work) — for example, a foundation permit — before construction documents for the entire project are submitted, provided adequate information and detailed statements for that part have been filed. The holder proceeds at their own risk without assurance the full permit will be granted. See § 106.12 for the CWUIC phased approval rule.

Decision‑relevant dimensions (quick reference)

Decision item Key values / what to provide Code Reference
Number of sets / format Two or more sets (or digital where allowed) § 106.1
Scale & clarity Drawn to scale; sufficient clarity to show location, nature and extent of work § 106
Vicinity plan Show details within 300 feet of lot lines (vegetation, slope, access, water supplies) § 106.7
Required substantiation Fuel‑loading classification and supporting data when required § 106.6
Retention One set kept on site; one set retained by code official ≥ 180 days after completion § 106.8
Phased approval Permit for part of the project allowed if adequate information for that part is filed; applicant proceeds at own risk § 106.12

Exceptions & special cases

  • The code official may waive submission of construction documents and supporting data that are not required to be prepared by a registered design professional if review is unnecessary to ensure compliance — check local application of this exception under § 106.1.
  • Phased approvals are explicitly allowed, but they only cover the part of work described in the submitted documents; they do not guarantee the permit for the entire structure or project. See § 106.12.
  • CWUIC requires WUI‑specific substantiation (fuel classification) when requested by the code official; if asked, you must include that data with plans per § 106.6.

Common mistakes

  • Submitting incomplete or non‑scaled drawings that fail to show location, extent or means of compliance — remember CWUIC requires clarity sufficient for code review (§ 106).
  • Failing to provide a vicinity plan showing the 300‑foot area around the lot when WUI details are required (§ 106.7).
  • Not keeping an approved set of plans on site or not ensuring one approved set is retained by the authority for the required period (§ 106.8).
  • Assuming a phased permit removes the need to submit full construction documents later — phased permits are provisional and do not guarantee final approval for the whole project (§ 106.12).

Worked example — concrete scenario

Scenario: You plan a new 2,500 ft² house in a WUI area and want the foundation permit to start work early.

  1. Prepare construction documents for the foundation work (foundation plans, soils report excerpts, basic structural info) and submit two sets of those documents to the code official. Indicate these are a phased submittal for foundations and include enough detail for the official to evaluate that portion. This is permitted under § 106.12.
  2. With the phased submittal, also include or note when the full set will be delivered; understand you proceed at your own risk because the full project approval is not guaranteed. § 106.12 requires this condition.
  3. For the full building permit, submit complete construction documents drawn to scale, including a vicinity plan showing vegetation, slope and access within 300 feet of lot lines, and the required substantiation about fuel classification if the code official requests it. See § 106, § 106.6, and § 106.7.
  4. After approval, one set of approved plans will be kept on site and one set retained by the authority for at least 180 days following completion, per § 106.8.

Numbers called out: 2 sets submitted; 300‑ft vicinity; 180‑day retention.

    2025 CALIFORNIA BUILDING CODE APPENDIX O-1

    on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.

    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

Can I submit plans digitally?

Yes — the CWUIC allows electronic/digital submissions where approved by the code official; the governing submittal rules are in § 106.1 and the general drawing/clarity rule is in § 106.

What exactly must the vicinity plan show?

The vicinity plan must show conditions within 300 feet of lot lines — other structures, slope, vegetation/fuel breaks, water supply systems and access roads — per § 106.7.

If I get a phased foundation permit, do I still need to submit the full building plans?

Yes — a phased permit covers only the part described in the submittal. You must still provide complete construction documents for the remainder of the project; phased permits are provisional and do not guarantee final approval for the whole building (§ 106.12).

How long must the authority keep approved plans?

One set of approved plans is retained by the code official for not less than 180 days from completion of the permitted work (or as required by state/local law), per § 106.8.

Who reviews deferred or phased submittals for compatibility?

When phased approvals or partial submissions are used, the code official reviews the submitted portion for compliance; the CWUIC requires that adequate information be filed for the part being permitted (see § 106.12).
