CWUIC · California Wildland-Urban Interface Code

How to apply for permits and what construction documents are required

If you’re applying for a permit under the CWUIC, submit **at least two sets** (or an approved digital set) of clear, scaled construction documents — prepared by a **registered design professional** when local law requires — and include a WUI site plan showing topography, access road width and grade, vegetation details, roof/ignition‑resistant information, and water supply; the **code official** can require extra documentation or waive submittal when appropriate.

What the code requires — in plain English

The California Wildland‑Urban Interface Code requires that, with each permit application, you submit construction documents (plans, engineering calculations, diagrams and other data) in not fewer than two sets or in digital format where the code official allows it. The documents must be prepared by a registered design professional when required by local statutes, and the code official may require additional documents under special conditions. This requirement is stated in § 106.1.

The Code also identifies § 105.4 (Permit application) as the controlling permit‑application section in the CWUIC table of contents, but the searchable preview I have does not include the full body text of § 105.4; therefore specific line‑by‑line application form contents in the CWUIC are not available here. See the CWUIC table of contents entry for § 105.4.

The single most important rule: submit at least two complete sets (or an approved digital set) of clear, scaled construction documents prepared by the appropriate design professional — the local code official can require more. § 106.1

Requirements in detail

Who prepares the documents

  • The construction documents must be prepared by a registered design professional where required by the statutes of the jurisdiction. § 106.1
    • Bold terms on first mention: registered design professional, code official.

How many copies / format

  • Submit not fewer than two sets of plans, engineering calculations, diagrams and supporting data, or submit in an approved digital format if allowed by the code official. § 106.1

What the plans must show (overview)

  • Plans must be drawn to scale, on suitable material, and be clear enough to show location, nature and extent of the work so compliance with the Code and applicable laws can be determined. See § 106.2 for the information standard (CWUIC references this requirement).

Site plan & WUI‑specific items

  • In addition to CBC site‑plan items, CWUIC requires WUI‑specific site plan information such as topography, width and percent of grade of access roads, landscape/vegetation details, locations of structures/building envelopes, existing/proposed overhead utilities, occupancy classification, types of ignition‑resistant construction, roof classification and site water supply systems. See § 106.3.

Vegetation management compliance before final

  • Prior to final building permit approval, the property must be in compliance with vegetation management requirements (Section 603 and PRC 4291 / Gov Code 51182 references). Acceptable methods include inspection/certification by a fire authority, enforcing agency, third‑party inspection, or property owner certification. See § 106.4.

Code official authority and exception

  • The code official is authorized to: (1) require additional documents prepared by a registered design professional where special conditions exist, and (2) waive submission of plans and data where the work is of a nature that plan review is not necessary. This is part of § 106.1 (Exception).

Decision table — quick reference

Decision question Required value / action Code reference
How many paper sets? Not fewer than two sets (unless digital allowed) § 106.1
Is digital acceptable? Yes — if allowed by the code official (digital submission permitted) § 106.1
Who must prepare drawings? Registered design professional where required by statute; otherwise as required by jurisdiction § 106.1
Can the code official ask for more? Yes — additional documents may be required for special conditions § 106.1
What must site plan show in WUI? Topography; access road width & % grade; vegetation; building locations; utilities; occupancy; ignition‑resistant construction; roof classification; site water supply § 106.3
Vegetation compliance before final? Property must comply with vegetation management (Section 603 / PRC 4291/Gov Code 51182) — inspection/certification options listed § 106.4

Exceptions & special cases

  • Waiver for simple work: If the code official finds the nature of the work makes plan review unnecessary, the official may waive submission of plans/calculations/inspection requirements. This is the official Exception in § 106.1.
  • Special conditions: Where special or unusual site or design conditions exist, the code official may require additional documents prepared by a registered design professional. § 106.1
  • Vegetation compliance method: The enforcing agency may allow local/state/federal fire authority inspection, enforcing agency inspection, third‑party inspection/certification, or property owner certification to document compliance before final approval. § 106.4

Common mistakes

  • Submitting only one paper set when two are required (or not confirming digital acceptance). See § 106.1.
  • Assuming plans do not need a registered design professional — check local statutes; if required, unsigned or non‑professional plans will be rejected. § 106.1.
  • Not including WUI‑specific site details (grade %, vegetation, roof classification, ignition‑resistant construction) — these are required for site plans in the CWUIC. § 106.3.
  • Forgetting to document vegetation management compliance before final — this can block final approval. § 106.4.
  • Expecting the CWUIC to list the exact application form fields in § 105.4 — the searchable preview of the CWUIC I have does not include the body text of § 105.4, so confirm local permit application form requirements with your enforcing agency.

Worked example — concrete scenario

Scenario: You are applying for a building permit for a 1,200 ft² addition to a home located inside a designated WUI area. Your jurisdiction requires design professionals for structural work.

Steps and numbers:

  1. Prepare construction documents: architectural plans, structural engineering calculations, foundation and roof details. Because structural changes are involved, have these prepared and stamped by a registered design professional. § 106.1
  2. Produce at least two full paper sets of the plans (or confirm with the local code official whether a digital submission is allowed and acceptable). § 106.1
  3. Include a CWUIC‑compliant site plan showing: topography (contours), the access road width and percent of grade (e.g., access road 16 ft wide with 8% grade), existing/proposed utilities, building envelope, roof classification and descriptions of ignition‑resistant construction for exterior elements. § 106.3
  4. If the property’s vegetation does not meet Section 603 / PRC 4291 standards at submittal, plan to either perform the work or arrange an inspection/certification. The project cannot receive final building permit approval until vegetation management compliance is documented per § 106.4.
  5. The code official may request additional supporting reports (e.g., geotechnical, wildfire hazard evaluation, or supplemental engineering) if special conditions exist — include budget/time contingency for additional submittals. § 106.1

Related provisions (CWUIC)

  • § 106.2 — Information on plans and specifications (drawn to scale; clarity; location/nature/extent).
  • § 106.3 — Site plan content specific to WUI (topography; access road width & percent grade; vegetation; roof classification; water supply; etc.).
  • § 106.4 — Vegetation management compliance required prior to final approval (lists acceptable inspection/certification methods).
  • § 105.6.1 — Refusal to issue a permit when application/documents do not conform (related permit administration provision).
  • § 105.8 — Permit expiration rules (timelines for commencing work); see CWUIC administrative sections for permit timing.

    1-4 2025 CALIFORNIA GREEN BUILDING STANDARDS CODE

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

    ADMINISTRATION

    101.9 Effective date of this code. Only those standards approved by the California Building Standards Commission that are effective at the time an application for a building permit is submitted shall apply to the plans and specifications for, and to the construction performed under, that permit. For the effective dates of the provisions contained in this code, see the appropriate application checklist and the History Note page of this code.

    101.10 Mandatory requirements. This code contains both mandatory and voluntary green building measures. Mandatory and voluntary measures are identified in the appropriate application checklist contained in this code.

    101.11 Effective use of this code. The following steps shall be used to establish which provisions of this code are applicable to a specific occupancy:

    1. Establish the type of occupancy.
    2. Verify which state agency has authority for the established occupancy by reviewing the authorities list in Sections 103 through 106.
    3. Once the appropriate agency has been identified, find the chapter which covers the established occupancy.
    4. The Matrix Adoption Tables at the beginning of Chapters 4 and 5 identify the mandatory green building measures necessary to meet the minimum requirements of this code for the established occupancy.
    5. Voluntary tier measures are contained in Appendix Chapters A4 and A5. A checklist containing each green building measure, both required and voluntary, is provided at the end of each appendix chapter. Each measure listed in the application checklist has a section number which correlates to a section where more information about the specific measure is available.
    6. The application checklist identifies which measures are required by this code and allows users to check off which voluntary items have been selected to meet voluntary tier levels if desired or mandated by a city, county, or city and county.

    SECTION 102—CONSTRUCTION DOCUMENTS AND INSTALLATION VERIFICATION

    102.1 Submittal documents. Construction documents and other data shall be submitted in one or more sets with each application for a permit. Where special conditions exist, the enforcing agency is authorized to require additional construction documents to be prepared by a licensed design professional and may be submitted separately.

    Exception: The enforcing agency is authorized to waive the submission of construction documents and other data not required to be prepared by a licensed design professional.

    102.2 Information on construction documents. Construction documents shall be of sufficient clarity to indicate the location, nature and scope of the proposed green building feature and show that it will conform to the provisions of this code, the California Building Standards Code and other relevant laws, ordinances, rules and regulations as determined by the enforcing agency.

    102.3 Verification. Documentation of conformance for applicable green building measures shall be provided to the enforcing agency. Alternate methods of documentation shall be acceptable when the enforcing agency finds that the proposed alternate documentation is satisfactory to demonstrate substantial conformance with the intent of the proposed green building measure.

    [HCD] Documentation of conformance for applicable green building measures shall be provided to the enforcing agency. All projects shall submit a completed Residential Occupancies Application Checklist that includes Chapter 4 residential mandatory measures and Tier 1 or Tier 2, as applicable. References to the measure-specific documentation used to show compliance shall be included. Alternate methods of documentation shall be acceptable when the enforcing agency f

Frequently asked questions

What exactly must I put on the site plan for a WUI permit?

At minimum the CWUIC says the site plan must show topography, width and percent of grade of access roads, landscape and vegetation details, locations of structures or building envelopes, existing/proposed overhead utilities, occupancy classification, types of ignition‑resistant construction, roof classification, and site water supply systems. See § 106.3.

How many paper sets of plans do I need to submit?

Not fewer than two sets, unless the code official has authorized a digital submission. § 106.1.

Do I always need a licensed architect or engineer to prepare the plans?

Only where required by the statutes of your jurisdiction; when required, construction documents must be prepared by a registered design professional. The code official can also require additional professional documentation when special conditions exist. § 106.1.

Can final approval be withheld for vegetation issues?

Yes. Before final building‑permit approval the property must be in compliance with vegetation management requirements (Section 603 and referenced state laws). Acceptable proof includes inspections or certifications listed in § 106.4.

What if my project is very small or routine?

The code official may waive the submission of plans and other data if they determine plan review is unnecessary for the nature of the work; this is the Exception to § 106.1. Always confirm with your enforcing agency.
