About Zone Zero Bay Area
Zone Zero Bay Area exists because two new California laws, AB 3074 and SB 504, changed what “fire-safe” means for a home’s perimeter, and most homeowners found out about it from a letter, a contractor’s estimate, or a neighbor rather than from a clear explanation of what the rules actually require. The source material sits in state fire marshal bulletins, county ordinance pages, and PDF appendices written for regulators, not for someone standing in their yard trying to figure out if their fence needs to come down.
This site takes that material and puts it into plain language: what Zone Zero is, which properties it applies to, what materials qualify, what a realistic compliance timeline looks like, and what the work tends to cost across Bay Area communities.
What We Cover
- Material comparisons: wrought iron, steel, aluminum, fiber cement, and other fencing systems weighed against the ember-resistant standard
- Compliance guides: what AB 3074 and SB 504 actually require, and how enforcement timelines are unfolding
- City-specific guides: fire hazard severity zone designations and local requirements for East Bay communities including the Berkeley Hills, Oakland Hills, Piedmont, Orinda, Moraga, Walnut Creek, Danville, and Lafayette
- Cost information: realistic pricing ranges based on material, linear footage, and property conditions
- A contractor directory: a vetted list of fire-safe fencing contractors serving the region, for homeowners ready to request a quote
Editorial Standards
Zone Zero Bay Area is not a contractor site, and it isn’t funded by any single fencing company. Our guides are researched independently against the actual text of state regulations, county fire department publications, and fire hazard severity zone maps. We update pages when regulations change or new information comes to light. The contractor directory includes vetted businesses, but the editorial content, the guides, comparisons, and city pages, is written independently of who is or isn’t listed there.
We are not a government agency, and this site is not an official source for compliance determinations. Fire hazard severity zone maps and property-specific requirements should always be confirmed with your local fire department or building department. What we offer is a starting point: a clear explanation of what the rules say, translated out of regulatory language, so you know what questions to ask before you make a decision.
Our Geographic Focus
Coverage centers on the San Francisco Bay Area, with particular attention to East Bay hillside communities sitting inside High and Very High Fire Hazard Severity Zones. These are the areas where Zone Zero requirements are being phased in first, and where the terrain, vegetation, and building density make defensible space rules matter most.
The 1991 Oakland Hills firestorm still shapes why defensible space rules exist in this part of the Bay Area, and it’s a big part of why the highest-risk hillside communities are first in line for the new standard. Homeowners in Alamo, San Ramon, Concord, El Cerrito, and Martinez face the same underlying questions, even where the exact zone designation differs, and our city guides are built to reflect those differences rather than treat the region as one uniform rule set.
