Fire-resistant decking for wildfire zones
Decking and details chosen for ember exposure in fire hazard areas.
Fire-resistant decking is a walking surface and frame chosen to resist ignition from embers and flame. Rules for it sit in California's wildland-urban interface code, which moved from Chapter 7A of the building code into Part 7 of Title 24 at the start of 2026.
The code lists test paths for the deck walking surface, including State Fire Marshal standards SFM 12-7A-4, which combines an under-deck flame exposure with a 40-minute burning-brand test, and SFM 12-7A-4A, an under-deck heat release test. We choose products with a listing for the path your office accepts, and we ask the office whether your parcel is covered.
A job runs in this order: site visit, parcel and zone check with the local office, written scope naming the product and its listing, permit if required, framing, decking, inspection.
We have no sourced price range for fire-resistant decking in our price file, so we do not publish one. Your price is a written quote after a site visit.
Common questions
Which rules apply to my deck?
The state wildland-urban interface code applies to parcels the local jurisdiction maps into a fire hazard area. Ask the building office with your parcel number; we do it with you at the site visit.
Is composite always fire-resistant?
No. It depends on the product's test listing. We check the listing for the code path your office accepts.
