Zone Zero Requirements in Santa Barbara County

This county isn't waiting for the state's deadline to take the first five feet seriously: county fire crews have been inspecting Zone 0 in the field since June 2026. Zone Zero (officially "Zone 0") is the ember-resistant zone around your home. Here's where it applies, which of the county's several fire authorities enforces it for you, and what your community's real story is.

Quick answer: California's Zone Zero law (AB 3074) requires an ember-resistant zone in the first 0 to 5 feet around homes in Very High Fire Hazard Severity Zones. In Santa Barbara County that includes the city's foothill neighborhoods, western Goleta, the Gaviota Coast, and North County zones. The City of Santa Barbara adopted the revised 2025 hazard maps on June 17, 2025, and Santa Barbara County Fire's field inspections have explicitly included Zone 0 since June 1, 2026. Final state regulations are expected in late 2026, with phased deadlines for existing homes from roughly 2027 to 2028.

The county's record

The Jesusita line

Santa Barbara's defining modern wildfire is its own. In May 2009 the Jesusita Fire came down out of the front country into the city's foothill neighborhoods: 8,733 acres, 80 homes destroyed along with 79 outbuildings and a commercial building, 15 more homes damaged, and somewhere between 30,000 and 35,000 people evacuated as Mission Canyon and the Rattlesnake Canyon area emptied out.

The Sundowner winds that drove it are this coast's signature fire weather, the same pattern that pushed the 2008 Tea Fire into the city's eastern foothills a few months earlier. Those two seasons drew the line the 2025 hazard maps still trace: where the front country meets the streets, the first five feet at each house is where the county's fire story gets personal. The full record is here; each community page carries only its own verified chapter.

The county map

Every community, grouped by its real sub-region

South Coast

The foothill front country, where the Jesusita Fire drew the line, and western Goleta's confirmed zones.

Gaviota Coast

The Refugio and El Capitan corridor, with its own confirmed anchors: the Sherpa Fire (2016) and the Gaviota Fire (2004).

North County

Confirmed Very High zones in and around three communities, each told without an invented fire story.

Carpinteria Valley

Real foothill geography and its own independent fire district; current severity tier honestly caveated rather than asserted.

Also Covered

Santa Maria's first-ever state hazard designation is Moderate, not Very High, and we say exactly that.

What must I do?

Zone 0: the first five feet

0 to 5 ft: Zone 0 0 to 5 ft: Zone 0 The ember-resistant zone wraps the entire structure
Zone 0 is the first 5 feet out from every wall, deck, and attached structure. Under the April 2026 Board of Forestry draft, this ring must be kept free of combustible material.

The rule is simple to state and hard to retrofit: nothing combustible in the first 5 feet from any structure. Combustible fences and gates touching the house, bark mulch against the foundation, woody shrubs under windows, firewood on the deck. Sundowner-driven ember fires are exactly the mechanism Zone 0 interrupts. Read the full requirements, or start with the two most common projects: fences and gates and landscaping.

Who enforces it?

A county of independent fire authorities

Santa Barbara County splits its fire authority more ways than most. The cities of Santa Barbara, Lompoc, and Santa Maria each run their own independent municipal departments (Santa Barbara's dates to 1881). The Santa Barbara County Fire Department serves Goleta under contract and the unincorporated communities directly, and it also holds a State Responsibility Area contract with CAL FIRE for backcountry wildland duties. Carpinteria and Summerland answer to the Carpinteria-Summerland Fire Protection District, an independent special district that is neither a city department nor county fire. Your community's page names yours, because under Zone 0 the local authority sets your specifics.

Yes, in the field. Santa Barbara County Fire has been running defensible-space inspections since June 1, 2026 that explicitly include the 0 to 5 foot Zone 0 alongside the traditional zones. Statewide mandatory deadlines for existing homes still follow the phased schedule expected to begin around 2027 to 2028.
