Zone Zero Pergola & Patio Cover Requirements

No — California's Zone Zero draft does not require you to take down an attached pergola. It changes what can be around and underneath it: the ground below must stay free of vegetation and combustible items, and Zone 0 is measured five feet outward from the pergola's edge rather than from your wall. None of it is in force today. The one setup the draft does restrict is the free-standing pergola sitting just off the house.

Removing an attached pergola is not required

The draft sets material requirements for combustible fences, gates and outbuildings. Pergolas are not on that list — an attached pergola is defined as part of the Occupied Structure, so it is the boundary Zone 0 is measured from rather than an object standing inside it. Nothing in the operative text requires an attached pergola to be removed, rebuilt, or clad in noncombustible material.

The five feet is measured from the pergola's edge

Zone 0 begins at the exterior surface of the wall, roof, attached deck, stairs or pergola and runs five feet out. A 12-foot pergola across the back of the house therefore turns a 5-foot zone into roughly 17 feet of regulated ground measured from the wall. Nothing about the pergola has to change; a lot about the planting and storage around it does.

Detached — but close — is the harder case

A self-supporting pergola within one foot of the house counts as attached, and is treated as part of the structure. Move it three feet out and it is no longer part of the structure — it is a combustible object standing inside Zone 0, which is the situation the rule restricts. Closer to the house is the better position here, not the worse one.

What Zone Zero requires for pergolas and patio covers

The question we get most often on the phone is whether a wood pergola attached to the house has to come down. Read against the operative text of the August 19, 2026 Board of Forestry final draft (approved 8–0; not yet law), the answer is no — and it is worth being precise about why, because the reasoning also tells you what does have to change.

A pergola is treated as part of the structure. The draft's definition of an Occupied Structure states that, for the purpose of determining an ember-resistant zone, it includes an attached deck, stairs, or pergola. Zone 0 is then defined as the area within five feet around each Occupied Structure, beginning at the exterior surface of the exterior wall, roof, attached deck, stairs or pergola and extending five feet out, or to the property line, whichever comes first. So the pergola is the boundary, not the target. Zone 0 begins where the pergola ends.

What the draft does require, where a pergola is concerned, is clearing rather than construction. The areas underneath decks, balconies, pergolas and stairs must be kept free of vegetation and combustible items — no storage, no firewood, no bark mulch, no planting beds. There must be a minimum five feet of vegetation-free buffer spanning out from the edge of any attached deck, stairs or pergola. And everything else Zone 0 asks for applies across that enlarged footprint: no combustible mulch, no stored firewood, no accumulated leaves or needles.

The one pergola situation that is a real problem is the free-standing one near the wall. The draft counts a self-supporting pergola as attached when it is within one foot of the structure. Beyond that foot it is not part of the structure — so a free-standing wood pergola two or three feet off the wall is a combustible structure standing inside Zone 0, and the draft states that no combustible materials are permitted within the full five feet of Zone 0. If it is small enough it may instead be read as an outbuilding, which must be built entirely of noncombustible materials. Either path leads to the same place. This is counterintuitive and worth repeating: the detached pergola near your wall is the exposed one. Attaching it, or rebuilding it in noncombustible materials, are the two ways out — and your local fire agency is the one who classifies it, so ask before you demolish anything.

Pergolas and Patio Covers: Frequently Asked Questions

Common questions about pergolas, patio covers and Zone Zero, answered clearly.

Do I have to remove my wood pergola?

No. Read against the operative text, the draft does not require removing an attached pergola. It sets material requirements for combustible fences, gates and outbuildings, and an attached pergola is not among them — it is defined as part of the Occupied Structure, which is the boundary Zone 0 is measured from. What the draft does require is that the area underneath stays free of vegetation and combustible items, and that the five feet spanning out from the pergola's edge stays vegetation-free. Your local jurisdiction may impose more than the state draft does, so check your local rule.

Does my pergola change where the 5 feet starts?

Yes, and this is the part people get wrong. Zone 0 begins at the exterior surface of the wall, roof, attached deck, stairs or pergola — so an attached pergola pushes the regulated ground outward by its own depth. A 12-foot pergola across the back of the house means roughly 17 feet of regulated ground measured from the wall. The pergola itself does not have to change; what you plant and store across that enlarged area does.

My pergola is free-standing a few feet from the house. Is that better?

It is worse, not better. The draft counts a self-supporting pergola as attached when it sits within one foot of the structure — at which point it is part of the structure and treated favorably. Past that foot it is a combustible object standing inside Zone 0, which is exactly what the rule restricts, and a small one may instead be read as an outbuilding, which must be entirely noncombustible. Moving it closer, or rebuilding it in noncombustible materials, are the two ways out. Your local fire agency makes the call on which category yours falls into, so ask before you demolish anything.

What has to change underneath the pergola?

The ground underneath has to stay clear. The draft requires that the areas underneath decks, balconies, pergolas and stairs be kept free of vegetation and combustible items: no stored firewood, no bark mulch, no planting beds, no bins or cushions left underneath. Enclosure is not required, and the draft does not offer it as an alternative — clearing is the requirement.

Do solid-roofed patio covers count the same way?

Yes. A solid-roofed patio cover attached to the house is treated like a pergola — part of the structure, with Zone 0 measured outward from its outer edge. Note that the definition excludes patios made of noncombustible materials, so a concrete or paver slab on its own is not what moves the line; the roofed, posted structure over it is.

When does any of this take effect?

There is no statewide effective date. The Board of Forestry approved the final draft on August 19, 2026, and the filing with the Office of Administrative Law was later withdrawn, so no state Zone 0 deadline is currently running. Some jurisdictions have their own ordinances with real dates — San Diego binds existing structures in the Very High Fire Hazard Severity Zone by February 28, 2027. If and when the state rule does take effect, the approved draft gave existing homes three years for the keep-it-clear provisions, including the area under a pergola, and three to five years on a local fire agency's timeline for the vegetation-free buffer around it. Check your local rule rather than the state draft.

Find out what your pergola actually requires

Most of what the draft asks for around a pergola is clearing, not construction. Before you budget for taking anything down, it is worth knowing whether your address is even in a fire hazard zone, and what your local jurisdiction requires on top of the state draft. A licensed local contractor can walk the property with you and tell you what is genuinely needed.
