Summary

Riverside County enforces 100-foot defensible space around structures in State Responsibility Areas and Local Responsibility Areas, with two clearance zones inspected annually by Cal Fire/Riverside County Fire.

Full Breakdown

Under Public Resources Code 4291 and Riverside County Ord. 787, owners must maintain Zone 1 (0-30 feet) free of dead vegetation, with limbed trees and noncombustible perimeters, and Zone 2 (30-100 feet) thinned and mowed. Cal Fire/Riverside County Fire performs annual Ready-Set-Go inspections. Wildland-Urban Interface communities such as Idyllwild, Anza, Aguanga, and Wine Country face heightened scrutiny. Owners receive a notice and reinspection before abatement. The county recovers contractor costs through property tax liens.

Violations & Fines

Failure to abate after notice triggers county-contracted clearing, with costs and administrative fees recovered as a property tax assessment.

Frequently Asked Questions

Does defensible space apply outside fire zones?

It is mandatory in State and Local Responsibility Areas; many county hillside parcels and mountain communities fall in SRA.

Can I be fined directly?

Yes. Continued noncompliance can lead to administrative citations under Ord. 725 in addition to abatement cost recovery.
