About This Site

Who publishes this site. Zone Zero Altadena is published by Zone Zero Property Inspections, a sole proprietorship. 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 Altadena. As of September 19, 2026 there is no statewide Zone 0 regulation in force, and we have not identified a local Zone 0 ordinance for Altadena.

What we are not. Zone Zero Property Inspections 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.

Phone calls. Calls to the number on this site are answered by an automated AI assistant and may be recorded and transcribed for quality.
