From Inside San Diego published 02/12/2026: Effective today, Zone Zero requirements apply to all new structures built in designated Very High Fire Severity Zones within the city of San Diego.
- Applicants for new building permits must demonstrate compliance with Zone Zero requirements during the permit review process, including maintaining an ember-resistant zone within five feet of the structure that is free of combustible materials.
- Existing home and property owners in Very High Fire Severity Zones must take proactive steps to meet Zone Zero guidelines by February 2027, in order to be in compliance with the state’s requirements.
The City of San Diego is notifying San Diegans of state-mandated “Zone Zero” wildfire safety requirements for all new structures built within Very High Fire Severity Zones. The Zone 0 requirements focus on the area closest to a home or building, where research shows they are most vulnerable to ignition from wind-driven embers during a wildfire.
“Creating defensible space is one of the most effective steps a homeowner can take to reduce their wildfire risk,” said San Diego Fire-Rescue Chief Robert Logan. “These statewide standards focus on the area closest to the home, where embers pose the greatest threat, and where informed and intentional actions today help protect homes, communities, and firefighters tomorrow.”
Zone Zero, also known as the ember-resistant zone, refers to the area within five feet of a structure, including attached decks and stairs.
While California has long required defensible space in Zones One and Two (extending up to 100 feet from structures), Zone Zero was added to address the immediate area where research shows many homes are first ignited by wind-driven embers in a wildfire. These requirements are intended to reduce ignition risk and strengthen overall community wildfire resilience throughout the state.
