Zone 0 Fence & Gate Materials

Zone 0 Fencing and Gates, Stocked in San Jose

California's Zone 0 rules cover the first five feet around a structure. For fences and gates, the requirement is straightforward: what touches your house cannot be something that burns.

We stock QuickScreen architectural aluminum fencing and gate systems at our San Jose warehouse. Aluminum does not ignite and does not carry flame, which is what the rule asks for. Send us your property lines and we will return a material takeoff and a quote in one business day.

What California Zone 0 actually says about fences

On August 19, 2026, the California Board of Forestry and Fire Protection approved the final draft of the statewide Zone 0 regulation. Three provisions apply to fencing:

1. No combustible fence or gate attached to a structure. A wood fence bolted to the side of a house is a fuel path leading directly to the wall.

2. A five-foot noncombustible span at the point of attachment. Any fence or gate that attaches to a structure, or comes within one foot of it, needs five feet of noncombustible material starting at the point of attachment or the closest point.

3. No new combustible fence within five feet of a structure after the rule takes effect. On the Local Responsibility Area track, this now covers fences running parallel to the structure, not only ones attached to it.

Repairs to an existing combustible fence may still use combustible materials.

Where the rule stands right now

The regulation is an approved final draft, not a rule in force. It goes to the Office of Administrative Law for review, then a five-day public comment window, then filing with the Secretary of State. There is no statewide effective date as of August 26, 2026.

Fence and gate obligations sit in the later compliance phase. For existing structures, that is three years from the effective date on the LRA track, or up to five years on the SRA track, on a timeline your local fire agency sets. New construction complies on the effective date itself.

Some jurisdictions have moved ahead of the state. The City of San Diego adopted its own Zone 0 ordinance effective February 28, 2026. Check your own parcel and your local fire authority before planning work.

This page is informational, not a compliance determination. Requirements depend on your parcel, your Fire Hazard Severity Zone designation, and your local authority having jurisdiction. Verify with the Board of Forestry or your local fire agency.

Does it apply to my property?

The rule applies in State Responsibility Areas and in Very High Fire Hazard Severity Zones within Local Responsibility Areas. Within our delivery area that includes large parts of Los Gatos, Saratoga, Monte Sereno, Almaden Valley, the East Foothills, Morgan Hill, Gilroy, Scotts Valley, Boulder Creek, Felton, Woodside, Portola Valley, and the Fremont and Milpitas hills.

Look up your parcel on the CAL FIRE Fire Hazard Severity Zone viewer, then confirm with your city or county fire department. Local agencies may adopt standards stricter than the state baseline.


What counts as noncombustible

Three terms get used interchangeably in fencing marketing and they mean different things:

Term What it means
Noncombustible The material itself does not ignite or sustain combustion. A property of the material.
Class A A flame-spread rating from a standardized test such as ASTM E84. A Class A rating does not make a material noncombustible.
Ignition-resistant A separate regulatory category under the Wildland-Urban Interface codes, generally involving treatment or assembly testing.

The Zone 0 rule text uses noncombustible. Metals meet that description. Wood, vinyl, and composite do not, regardless of any treatment or coating.

One thing worth being straight about: no fencing product in California carries a state fire approval. The State Fire Marshal's Building Materials Listing program covers decking, windows, siding, doors, and under-eave products. There is no fencing category. Any supplier claiming a CAL FIRE-approved or state-certified fence is describing something that does not exist. What we can tell you is that structural aluminum does not burn.


Three situations, three solutions

Your fence attaches to the house

You need five feet of noncombustible fence starting where it meets the wall. You do not need to replace the entire run. One aluminum panel and a post at the attachment point satisfies the requirement, and the rest of the fence can stay as it is.

We sell the transition span on its own. Bring us a photo and a measurement.

A wood gate sits against the wall

Side-yard gates are the most common attachment point on a residential lot, and the easiest fix. A QuickScreen aluminum pedestrian gate replaces it directly, in a slat pattern that reads as a deliberate design choice rather than a patch.

Your fence runs parallel, inside five feet

Under the LRA track of the approved text, new combustible fence is not permitted within five feet of a structure whether attached or parallel. If you are planning new fence along the side of a house on a narrow lot, build that run in aluminum from the start.


The material we stock

QuickScreen is an architectural aluminum slat system. It has been sold and installed in Australia for over ten years, where the same fence-to-house ignition problem drives building standards.

Construction

  • Structural-grade 6005 aluminum alloy
  • AAMA 2604 powder coat finish with a 25-year finish warranty
  • Patented friction-fit post and frame system. Slats lock in without welding or visible fasteners.
  • Panels adjustable in height and width, so runs finish clean against posts, pillars, and walls
  • Post systems for new fence; side frame systems to work between existing posts, pillars, or walls

Profiles

  • Horizontal slat, in several slat widths including a 2.55" architectural profile
  • Vertical slat
  • Full privacy tongue-and-groove, using a 6" board profile that stacks into a continuous screen
  • Combination layouts

Finishes Textured Black, Monument, Pearl White Gloss, and Woodland Grey.

What it does not need No staining, no sealing, no repainting, no rot repair. It does not rust, warp, or feed a fire.


Buying from us

We are a fence material supplier, open to the public. We do not perform installation. Many of our customers install themselves; the friction-fit system is designed for that. Others buy through their fencing contractor, and we are happy to quote either way.

How a quote works

  1. Send property lines, a site plan, or photos with measurements
  2. Tell us where the fence meets the house, and whether there is a gate at that point
  3. We return a quote with current pricing 
  4. Pick up at our San Jose warehouse or receive your items by local delivery

Homeowner and contractor pricing both available. Contractors can apply for a trade account with credit terms.


Questions

Do I have to replace my whole fence? No. The requirement is a five-foot noncombustible span measured from the point where the fence meets the structure. The rest of the fence line is unaffected, and fences more than five feet from a structure are outside the rule entirely.

Is this required right now? No. The regulation is an approved final draft pending review by the Office of Administrative Law. There is no statewide effective date, and fence obligations fall in the later compliance phase, three to five years after that date. Local jurisdictions may have their own timelines.

Can I repair my existing wood fence? Yes. The approved text expressly permits repairs to an existing combustible fence using combustible replacement materials. The restriction applies to new fence within five feet of a structure.

Why aluminum instead of steel? Both are noncombustible. Aluminum will not rust, weighs far less to handle and install, and the slat systems come in privacy configurations that steel picket and ornamental lines do not. If you want steel, chain link, or ornamental iron, we stock those too.

Will a metal fence look out of place on my house? The slat profiles are an architectural product, not a utility fence. If you are only replacing the five feet at the house, we will help you pick a profile and finish that reads as intentional against the existing fence.

Do you install? No. We only supply materials and do not keep of list of recommended installers. 

Do you deliver? Yes, throughout Santa Clara, Santa Cruz, San Mateo, and Alameda counties. Will-call pickup is also available at the San Jose warehouse.
