Noncombustible helps. Check your city’s rule too
Based on your answers: a noncombustible section at the house, such as metal or masonry that passes ASTM E136, is what the adopted state rule calls for in the State Responsibility Area and Very High zones. Some cities set their own rules, and our city guide lists the ones we have checked, with sources.
The state rule is not in force yet: the Board of Forestry adopted it on Aug 19, 2026, and it was not in effect when we last checked on Nov 10, 2026.
The state rule covers only the State Responsibility Area and local Very High Fire Hazard Severity Zones, so your zone decides whether any of this applies. Look up your address on the CAL FIRE fire hazard severity zone map (on CAL FIRE's website).
