One local briefing, built from separate evidence layers: what the state has published, where an
instrument is documented to apply, what still depends on a map or project fact, and which plant
records are documented in California. A ZIP personalizes priority; it does not decide a parcel boundary.
What is established here
California maps WUI and uses CWUIC on those lots. Transfer rules live in AB 38. Read how to read an FHSZ map. Oregon is a different book. Confirm the adopted Title 24 Part 7, not unmodified IWUIC.
California applies 2025 CWUIC Chapter 5 to new buildings in mapped State Responsibility Area fire-hazard zones and in locally designated High and Very High zones; the official map, permit facts, any local amendment, and the enforcing agency still govern a project.
Scope: mapped area · effective 2026-01-01
Official map linked. CAL FIRE's official statewide viewer accepts an address and displays State and Local Responsibility Area fire-hazard zones; the local jurisdiction remains the source for an adopted Local Responsibility Area designation and project decision. Open official map →
Still verify with the authority
Check the parcel in the official hazard map.
Confirm that the project type and permit scope trigger the provision.
Confirm the result with the authority having jurisdiction.
Child-place and sibling claims stay on those place pages, their object URLs, and the JSON twin.
