Building on Raw Land in Butte County: WUI Rules After the Camp Fire

What the Camp Fire actually destroyed, and where

The Camp Fire ignited on November 8, 2018, in the Feather River Canyon area and, driven by strong dry winds, burned through the incorporated town of Paradise and the unincorporated communities of Magalia and Concow, along the ridge above Chico and Oroville. It destroyed nearly 19,000 structures and killed 85 people, standing as the deadliest and most destructive wildfire in California history at the time it occurred. The fire's cause was traced to Pacific Gas & Electric transmission equipment, a finding that carried major consequences for the utility separate from the land-use questions this page addresses.

California's Chapter 7A wildland-urban interface building code

California's building code includes Chapter 7A, a statewide set of construction standards for buildings in designated Wildland-Urban Interface (WUI) fire areas -- requiring ignition-resistant materials and assemblies for roofing, siding, eaves, vents, windows, and decking, specifically to reduce a structure's vulnerability to wind-driven embers, which is how most homes were lost in fires like the Camp Fire. Most of the burned area in and around Paradise, Magalia, and Concow falls within a WUI designation, meaning rebuilding there -- and any new construction generally in Butte County's forested foothill terrain -- is subject to these requirements rather than standard, non-WUI building code.

Alongside Chapter 7A's material standards, California's defensible-space law (Public Resources Code Section 4291) requires clearing and modifying vegetation in zones extending up to 100 feet from a structure in a State Responsibility Area, to slow fire spread and give firefighters a defensible perimeter. Both requirements apply on top of, not instead of, Butte County's ordinary building permit process.

What to actually check for a specific parcel

For any parcel in or near the Camp Fire burn area -- or generally anywhere in Butte County's forested foothill terrain -- confirm the parcel's specific Wildland-Urban Interface and fire-hazard-severity zone designation with Butte County Development Services and CAL FIRE before finalizing building plans, since these designations determine which Chapter 7A provisions and defensible-space requirements actually apply. It's also worth asking the county directly about any streamlined permitting process that may still apply to rebuilds on parcels that were destroyed in the fire, since post-disaster jurisdictions sometimes maintain expedited review paths for verified rebuild projects that differ from ordinary new-construction permitting.

Separately, insurance availability and cost for wildfire-zone construction in this specific area has been a widely reported, evolving issue statewide since the fire -- confirm current insurability directly with carriers or a broker before committing to a purchase or build plan, rather than assuming pre-2018 insurance conditions still apply.
