What to clear in each zone

Tap what is done. CAL FIRE says Zones 1 and 2 are required by law. Zone 0 is the state's newer rule for the first 5 feet. The Board approved it in August 2026, but it is not in effect yet.

In unincorporated Sonoma County, the county's vegetation rules (Chapter 13A) also apply, with inspections from late spring. Check your address to see which rules cover you. (Permit Sonoma)

Some insurers now require the IBHS Wildfire Prepared Home designation for new policies in high-risk areas, and it requires a clear 5-foot zone. What insurers look for · How to keep your insurance.
