Confirm whether the jurisdiction enforces NFPA 1140, the IWUIC, or its own wildland rules, and which edition, then trace fire apparatus access, water supply, defensible space, and ignition-resistant construction through the site, civil, landscape, and architectural documents. AI can flag conflicts; the designer, the fire marshal, and the authority having jurisdiction decide compliance.
What does NFPA 1140 cover?
NFPA 1140 is the Standard for Fire Protection in Rural, Suburban, and Wildland/Urban Interface Areas. NFPA’s page states that, under its Emergency Response and Responder Safety Document Consolidation Plan, NFPA 1140 combines the former NFPA 1051, NFPA 1141, NFPA 1143, and NFPA 1144. Parts of the consolidated standard deal with responder qualifications and wildland fire management rather than buildings, so a drawing review uses only the parts the project’s approvals rely on.
NFPA’s official NFPA 1140 page identifies the 2027 edition as current when checked on October 6, 2026. Confirm the edition, local amendments, and project scope that actually govern the work. The publisher’s newest edition does not establish local adoption.
Some jurisdictions adopt the ICC’s code for these areas instead, covered in the IWUIC guide, and others write wildland requirements into their fire code; see the NFPA 1 guide and the California Fire Code guide. Projects that cite one of the four older standards may still be reviewed under it. Record the document, edition, and fire hazard designation the authority names before comparing anything.
Gather the site, access, water, and envelope documents
Collect the site plan with fire apparatus access roads, turnarounds, gates, and grades, the civil utility plans with hydrants, tanks, or other water sources, any fire flow or water supply letter, the landscape and fuel modification plans, the architectural elevations, roof plan, wall sections, and the details for vents, eaves, decks, and glazing, the fire protection drawings, and the fire marshal’s or planning conditions of approval.
Wildland approvals often arrive as conditions in a letter, not on a sheet. Upload the letter so each condition can be traced into the drawings.
Trace the wildland conditions through the set
| Review question | Sources to compare | Decision to record |
|---|---|---|
| Governing document and hazard area | Code analysis, conditions of approval, site plan notes | Confirm one wildland document, edition, and hazard designation across the set. |
| Fire apparatus access | Site plan, civil grading, gate details, conditions of approval | Match the access route, turnarounds, and gates between the site and civil sheets and the conditions. |
| Water supply | Civil utility plans, tank or hydrant details, water supply letter, fire protection drawings | Check that the water source the conditions require is drawn, located, and connected. |
| Defensible space and vegetation | Landscape plan, fuel modification plan, site plan | Find plantings or structures inside zones the fuel modification plan keeps clear. |
| Ignition-resistant construction | Elevations, wall sections, roof plan, vent and eave details, specifications | Compare the materials and vents shown with the construction the approvals require. |
| Conditions of approval | Approval letter, general notes, sheet index | List conditions with no matching drawing, note, or detail. |
Use the civil and site checklist for grading and access, and the NFPA 24 guide where a private fire service main feeds the hydrants. Water supply test data follow the NFPA 291 flow test guide, and a stored water tank the NFPA 22 guide.
Example: the conditions require a water tank the site plan omits
Hypothetical example. A hillside house is approved with conditions that call for a dedicated fire water tank and a turnaround near the house. The civil plan shows the turnaround, but no sheet shows the tank, and the landscape plan places a planting bed where the conditions require cleared vegetation.
The conditions of approval require a fire water tank and cleared vegetation near the house. No sheet shows the tank, its connection, or its access, and the landscape plan places planting in the cleared area. Please add the tank and coordinate the landscape plan with the conditions.
The civil engineer locates the tank and its connection, and the landscape architect revises the planting. The fire marshal confirms the result against the document the jurisdiction enforces.
Review wildland documents with Groundbook
Upload the current project PDFs and relevant specifications to Groundbook. Identify the governing issues and add the applicable NFPA 1140 reference from a copy you are licensed to use, where the license permits uploading it. State the edition, amendments, review area, and known exclusions in your instructions.
Compare the conditions of approval and fire marshal letter with the site plan, civil utility and grading plans, landscape and fuel modification plans, architectural elevations, roof plan, wall sections, and vent and eave details. Flag conditions with no matching drawing, water sources that are required but not drawn, and materials or plantings that differ from the approved basis. Use the supplied NFPA 1140 edition and local requirements and cite both sources.
Groundbook links each potential finding to the sheets and the approval letter involved. Upload the conditions as a reference so the comparison can use them.
Document review does not calculate fire flow, assign a hazard designation, or replace the designer, the fire marshal, or the authority having jurisdiction.
