Your fence is the first thing the new rules touch

The combustible-fence restriction takes effect immediately when final Zone Zero regulations are adopted. Here's what that means for Montecito's gates, board fences, and estate frontages.

Quick answer: Under the April 2026 draft, combustible fences attached to structures in Very High hazard zones are restricted immediately upon adoption of the final Zone 0 regulations, expected late 2026. The fix is a noncombustible section or gate in the first 5 feet of the ember-resistant zone at each structure. Fence work in California requires a CSLB Class C-13 licensed contractor.

Why fences first

A wood fence is a fuse connected to your house

Ember research is unambiguous about the mechanism: a burning fence attached to a wall delivers flame directly to the structure, and in wind-driven fires embers find that fuel long before the front arrives. On a Montecito parcel the exposure multiplies with the buildings: the main residence, the guest house, the cabana, and the garage each count, and a wood gate or fence section touching any of them is inside the rule.

The common retrofit is smaller than people fear, and often invisible to the eye that matters. Replace the final 5 feet where fencing meets each structure with a noncombustible panel or metal gate, and the rest of the run stays. Wrought iron and masonry, already at home on these frontages, comply outright. Costs vary by material and run; any quote should come from a licensed contractor after seeing the property. The free assessment tells you how many linear feet at how many structures are actually in the zone before anyone talks price.

Beyond the fence

Gates, and what Zone 0 means for them

Gates get the same treatment as fencing where they sit in the ember-resistant zone: noncombustible materials in the first 5 feet. A metal pedestrian gate at the house corner is often the single cheapest compliance win on the property.

Questions

Quick answers

Do I have to replace my whole fence?

Usually no. The requirement targets the portion attached to or within 5 feet of the structure. On estate lots the common fix is replacing the final run and gates at each structure with noncombustible sections, and keeping the rest, including perimeter fencing well away from buildings.

What fence materials count as ember-resistant?

Noncombustible materials: steel, aluminum, masonry, and certain rated composites. Wrought iron and masonry, already the vernacular of many Montecito frontages, comply naturally; the wood gate at the house corner and the board fence tying into the garage are what the immediate-effect restriction targets.

Who can legally do fence work in California?

A CSLB-licensed contractor. Fencing is Class C-13. Any referral through this site is licensed, and the free assessment is how to start.
