Statewide California requires CWUIC 2025.

California is the mapped-state case: CWUIC 2025 applies on lots the state maps, effective 2026-01-01, and transfer rules ride AB 38. What applies to your house turns on the map first — the hazard-zone lookup, then the code.

What the state leaves open is precise: the official map for your lot, your project's scope, and the final confirmation. What we can't tell you yet is that list, not a shrug.

The plant corpus here is the directory's largest: 717 records documented across USDA half-zones 5b through 11a, with 221 flagged invasive or noxious — and 111 product matches across 9 parts of the house on the construction side. Living here opens the biggest file.

What applies in California

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.
