About This Site

Who publishes this site. Zone Zero San Diego is published by Firewise Fences, Inc., a Delaware corporation working on solving the Zone 0 regulations for fences and gates at scale. This site is an independent guide: it is not affiliated with, endorsed by, or operated by any government agency.

What this site does. We publish plain-language information about California's Zone 0 defensible-space regulations and how they may affect homeowners in San Diego. If you request it, we can connect you with an independent CSLB-licensed local contractor for a free assessment. We may receive compensation when we connect you with a contractor.

What we are not. Firewise Fences, Inc. is not a contractor and does not perform assessments or installations. Nothing on this site is legal advice; regulations change, and your local jurisdiction is the authority on what applies to your property.
