Zone Zero Fence Rules in Pasadena

Once California adopts its final ember-resistant zone regulations (expected late 2026), new combustible fences within 5 feet of a home in a Very High Fire Hazard Severity Zone are prohibited immediately, with no grace period. Existing wood fences fall under Phase 2: the City of Pasadena sets the replacement deadline, up to 5 years after adoption.

Why fences are named in the law

A wood fence is a fuse connected to your house

Embers don't need to reach your house. They only need to reach your fence. A wooden fence that touches your home carries fire straight to the wall, the eave, the attic vent.

Pasadena's older neighborhoods make this worse in a specific way: Craftsman-era wood construction, long side-yard fence runs, and hillside lots in the San Rafael Hills and the foothills above the 210. IBHS ember research is the reason fences are called out by name in the April 2026 draft.

During the Eaton Fire, wind-driven embers crossed well ahead of the fire front on Pasadena's northeast edge. The first five feet decided a lot of outcomes that night.

The Materials

What a Zone 0 compliant fence looks like

You have three material paths, and one shortcut. Compliance is about the five feet nearest your home, not necessarily the whole fence line.

The connection-point fix
ZONE 0 · 0–5 FT EXISTING WOOD FENCE · PHASE 2 NONCOMBUSTIBLE PANEL YOUR HOME WOOD FENCE PHASE 2 NONCOMBUSTIBLE PANEL · ZONE 0 YOUR HOME
The shortcut: a noncombustible gate or panel in the last five feet breaks the fuse without replacing the whole fence line. It's the detail inspectors will look at first.

Metal

Steel, aluminum, and wrought iron all pass in Zone Zero. Powder-coated steel is the most common like-for-like swap for wood privacy fencing.

Masonry & block

Block walls, brick, and stone are noncombustible and permanent. Highest cost, zero maintenance, best ember protection.

Fire-rated composite

Some composite products carry fire ratings expected to comply under the final regulations. Verify the listing before you buy. Most standard composite is combustible.

The critical 5 feet

You may not need to replace the whole fence. A noncombustible gate or panel where the fence meets your house breaks the fuse. It's the detail inspectors will look at first.

Common Questions

Fence questions, answered

Do I have to tear out my wood fence right now?

No. The immediate rule covers only new fences. Existing fences fall under Phase 2, and the City of Pasadena sets that deadline, up to 5 years after the state adopts final regulations. But contractor calendars fill fast once deadlines land.

Can I keep most of the fence and replace just the last section?

Usually, yes. The regulation targets the 5 feet nearest the structure. Swapping in a metal gate or noncombustible panel at the connection point is the most cost-effective path to compliance on many Pasadena lots.

My Craftsman home has period-appropriate wood fencing. Are historic properties exempt?

The current draft does not carve out a blanket historic exemption for fencing in the ember-resistant zone. Pasadena has strong design-review traditions in its landmark districts, so pair any replacement with the city's design guidance, but plan on the five feet nearest the structure going noncombustible.

Does vinyl fencing comply?

No. Standard vinyl is combustible and deforms under radiant heat. Metal, masonry, or verified fire-rated products are the compliant options.
