Orange County: How to Buy a Home in a Wildfire Zone After the Norte Fire: Zone 0, Defensible Space Inspections and the Fire Disclosures to Ask For (November 2026)

Four weeks after the Norte Fire burned through the hills between San Clemente and San Juan Capistrano, wildfire rules for California homes are changing again. On November 5, 2026, the state Board of Forestry and Fire Protection adopted a revised "Zone 0" rule for the first five feet around homes in the highest-risk areas. The rule is not in force yet, but it is headed for state review. Meanwhile, the protections buyers already have are in place right now. Sellers of homes in High or Very High Fire Hazard Severity Zones must give buyers proof of defensible space or a signed agreement, and for older homes they must also give a fire-hardening disclosure. In much of Orange County the defensible space inspection is free.

Wildfire risk isn't just a canyon issue in Orange County anymore. When the State Fire Marshal released its 2025 maps, Irvine's hazard zones expanded into Orchard Hills, Woodbury, Portola Springs, Quail Hill, Turtle Rock, Laguna Altura, Los Olivos and Irvine Spectrum. This guide explains what the rules require, how to check any address, what to ask the seller, how to run the numbers, and how to use what you find to negotiate.

What's in the news

• The Norte Fire. Published local coverage reported that the fire started shortly after 11:30 a.m. on Friday, October 16. Strong winds pushed it toward San Juan Capistrano, where seven homes were damaged or destroyed, and it grew to about 570 acres. A complaint filed for a San Juan Capistrano resident alleges that San Diego Gas & Electric equipment caused the fire. SDG&E has said the cause of a nearby outage is still under investigation and that there is no basis to link its equipment to the ignition. The cause has not been officially determined.
• Smoke damage and insurance claims. On November 11, published local coverage reported that some Norte Fire residents whose homes are still standing have serious smoke and ash damage and are disputing claims with the California FAIR Plan. For one home, the coverage reported a damage estimate in the six figures, compared with a five-figure estimate from the FAIR Plan. The FAIR Plan said it evaluates every claim on its merits and pays covered claims, including smoke damage, up to policy limits.
• The Zone 0 rule was adopted again on November 5. The Board of Forestry adopted revised emergency regulations for Zone 0, the ember-resistant zone within five feet of a structure. The Board had withdrawn its August version from the Office of Administrative Law on September 8. The new rule takes effect only after the Office of Administrative Law approves it and it is filed with the Secretary of State. According to summaries of the Board's notice, the Board expected to submit it on or after November 13. As of this writing, there is no effective date.
• The insurance industry weighed in. An insurance industry group called the revised rule "an important statewide baseline." It also said concerns remain about whether compliance will be "sufficiently consistent and verifiable," and it urged homeowners to go further and keep the first five feet noncombustible.

The market snapshot (October 2026)

Source: public housing-market data, county core metrics, October 2026. The price-cut share is the published share of listings with a price cut.

Mortgage rates: The national average 30-year rate was 7.11% on November 12, 2026, down from 7.18% the week before. A year earlier it was 6.24%. The 15-year average was 6.45%.

In short: buyers have more homes to choose from and more time to decide. About one in five listings has had a price cut. That gives you room to ask for wildfire-related repairs, credits or price reductions, especially on homes that have been on the market longer than the 56-day median.

The rules, in plain English

1. Fire Hazard Severity Zones: the map that triggers everything

The State Fire Marshal rates land as Moderate, High, or Very High fire hazard. Some areas are State Responsibility Areas (SRA, mostly unincorporated wildland where the state is responsible), and others are Local Responsibility Areas (LRA, cities and other places where local agencies are responsible). The 2025 LRA maps redrew many Orange County city zones:

• Irvine adopted the 2025 map without changes. It took effect July 23, 2025 and expanded the zones into Orchard Hills, Woodbury, Portola Springs, Quail Hill, Turtle Rock, Laguna Altura, Los Olivos and Irvine Spectrum. New construction and major renovations with permit applications filed after that date must meet the building and fire code rules for the new zones.
• Laguna Beach adopted its 2025 LRA maps on June 24, 2025 and publishes an address-search map.

A home that wasn't in a zone when the seller bought it may be in one now. Check the current map. Don't rely on the seller's old paperwork.

2. The defensible space disclosure (California Civil Code §1102.19, the "AB 38" rule)

Since July 1, 2021, sellers of homes in a High or Very High Fire Hazard Severity Zone have had to give the buyer documentation that the property complies with state defensible space law (Public Resources Code §4291) or the local vegetation management ordinance. If the seller doesn't have that documentation, the buyer and seller must sign a written agreement in which the buyer agrees to get it, generally within one year after closing. The law also says that agreement does not stop fire agencies from enforcing defensible space rules.

3. The fire-hardening disclosure for older homes (Civil Code §1102.6f)

If the home is in a High or Very High zone and was built before January 1, 2010, the seller must give a notice saying the home was built before the current wildland-urban interface building codes. The notice must also:

• List the state's low-cost retrofits and say which ones the seller completed while owning the home (required since July 1, 2025).
• Disclose which of these vulnerable features the seller knows about:
  • vents with openings larger than 1/8 inch, or vents that are not flame- and ember-resistant
  • untreated wood shake or shingle roofs
  • combustible landscaping or materials within five feet of the home or under an attached deck
  • single-pane or non-tempered windows
  • loose or missing bird stops or roof flashing
  • gutters without metal or noncombustible covers

This disclosure is your free to-do list. Every item checked "yes" is something to price out before you remove contingencies.

4. Defensible space today (Zones 1 and 2)

The Orange County Fire Authority (OCFA) describes defensible space as "a 360˚ approach, 100 ft from a structure or a property line." The Board of Forestry describes the zones this way:

• Zone 1 (5 to 30 feet): remove dead leaves and debris from the yard, roof and gutters; keep branches at least 10 feet from chimneys; clear under decks; space plants apart; keep 10 feet of clearance around outbuildings and propane tanks.
• Zone 2 (30 to 100 feet): mow grass to a maximum of 4 inches; space shrubs and trees; remove dead vegetation; prune lower branches.

Many master-planned communities in South County and the foothills also have HOA-maintained fuel modification zones. OCFA's guideline says maintenance duties for those zones must be recorded in the CC&Rs or deed restrictions. It also requires a signed homeowner disclosure when the innermost zone is on private lots and the outer zones are HOA common area.

5. Zone 0 (0 to 5 feet): adopted November 5, not yet in force

As summarized from the Board's November 5 text, the revised rule applies in State Responsibility Areas and in Very High zones within Local Responsibility Areas. It does not apply to LRA properties that are not in a Very High zone. Key points:

• No vegetation under eaves, within 1 foot of exterior walls where there is no eave, within 2 feet of windows, doors and vents, or within 5 feet of attached decks, stairs and pergolas.
• No combustible materials such as bark or wood-chip mulch, fallen leaves, firewood, or wood and plastic items, with limited exceptions. The area under decks, balconies, stairs and pergolas must be kept clear.
• Allowed plants: lawn and ground cover up to 3 inches tall; non-woody plants 3 to 18 inches tall in clumps of 1 square foot or less, spaced at least 2 feet apart; potted plants in noncombustible containers of 5 gallons or less, also 2 feet apart. No new trees. Existing trees can stay if they meet the clearance rules.
• Fences and gates: a fence or gate attached directly to the house must be entirely noncombustible. A fence that touches the house or comes within 1 foot of it needs a 5-foot noncombustible section. Any new fence or gate within 5 feet must be noncombustible. Repairs to existing fences are exempt.
• Phase-in for existing homes, counted from the effective date:
  • At the effective date: keep roofs and gutters clean; remove dead branches; keep live branches 10 feet from chimneys; follow the new-fence rule.
  • Within 3 years: remove firewood and other combustibles; clear under decks, stairs and pergolas; meet the remaining branch clearances.
  • Within 3 to 5 years: meet the clear buffers, the planting limits and the rules for existing fences. In covered LRAs, a local ordinance can set a later deadline for this last phase.

Until the rule takes effect, Zone 0 work on an existing home is recommended rather than required statewide. The existing 100-foot defensible space law and local rules still apply. The final wording is whatever the Office of Administrative Law files, so check again before you close.

Who inspects in Orange County

OCFA does defensible space disclosure inspections in its own jurisdiction. Here is what its FAQ says:

• The inspection is free, takes about 30 minutes, and covers the exterior only.
• The owner or listing agent requests it. A buyer's agent can request it with the owner's permission.
• Someone 18 or older must attend and be able to sign documents, even if the home is vacant.
• If the property passes, a compliance form is emailed within 1 to 3 business days. If it doesn't, the inspector leaves a handwritten notice listing the work needed, and OCFA does not keep copies of those notices.
• Compliance documentation is valid for 6 months from the inspection date.
• The inspection can be deferred to the buyer, but it must take place within 1 year of the sale.
• In HOA communities, the inspector considers the areas the HOA is responsible for.
• Multi-unit properties with 5 or more units are not required to have the inspection, according to the C.A.R. addendum.

OCFA uses a "pink mapped" area on its Property Locator to decide whether an inspection is required. A natural hazard disclosure report may show a fire zone that OCFA does not inspect, because those reports can use maps that include lower-severity zones.

Some cities are outside OCFA's jurisdiction, and you must call the city's own fire department. OCFA lists Anaheim (714-765-4040), Brea (714-990-7655), Costa Mesa (714-754-5000), Fullerton (714-738-6500), Fountain Valley (714-593-4436), Huntington Beach (714-536-5411), Laguna Beach (949-497-0700), La Habra through Los Angeles County Fire (626-969-2375), Newport Beach (949-644-3106), Orange (714-288-2500) and Placentia (714-993-8135).

Run the numbers

Illustration 1: the payment on a median-priced home. Assumptions: the October median list price of $1,260,000, 20% down ($252,000), a $1,008,000 loan, and a 30-year fixed rate of 7.11%. Principal and interest come to about $6,781 a month. With 10% down ($126,000, a $1,134,000 loan), principal and interest are about $7,628 a month. For comparison, a year ago the median list price was $1,362,500 and the rate was 6.24%. With 20% down ($1,090,000 loan), that was about $6,704 a month. Lower prices have nearly offset higher rates. These figures leave out property taxes, insurance and HOA dues, and none of them is a loan quote.

Illustration 2: price cut vs. seller credit for wildfire work. Assumption: bids for the items found during inspections total $18,000. This is a hypothetical number for the example, not a market price for retrofits. Bids might cover replacing a wood gate attached to the house, upgrading vents to 1/16- to 1/8-inch ember-resistant mesh, adding gutter covers and clearing brush.

• As an $18,000 price cut on the $1,260,000 home with 20% down: the price becomes $1,242,000, the loan $993,600, and principal and interest about $6,684 a month. That is about $97 a month less for the life of the loan, plus $3,600 less in down payment. A lower purchase price also means a lower Prop 13 base value. At an assumed 1% base tax rate (actual Orange County rates vary by tax rate area), that saves roughly $180 a year.
• As an $18,000 seller credit: you get cash at closing instead, so the work can be done right away. But lenders limit how much a seller can contribute and what it can be used for. Ask your lender about its limit before you write the credit into your counteroffer.
• As a seller repair: the seller does the work before closing. Ask for paid invoices, photos and, if the work affected the inspection, a new compliance form.

Which one is best depends on how much cash you have, your lender's rules, and whether you trust the seller's contractor. With 19.4% of listings showing a price cut and pending listings down 22.9% from a year ago, this is a reasonable market to ask for one of the three.

Step-by-step: how to buy in a wildfire zone

Step 1. Check the zone before you tour. Look up the address on the State Fire Marshal's Fire Hazard Severity Zone viewer or your city's map (Irvine and Laguna Beach both have address-search maps). You can also start with our [hazard map](/property-tools.html#hazards) as a first screen, then confirm the official rating. Write down three things: the rating (Moderate, High or Very High), whether it's SRA or LRA, and which fire agency covers the address (OCFA or a city department).

Step 2. Get insurance quotes before you remove contingencies. Ask an agent or broker for quotes as soon as you're serious about a home, not after your offer is accepted. Ask what wildfire mitigation discounts the insurer offers. Our [wildfire insurance guide](/property-tools.html#fire-insurance) explains what typically affects quotes. The California Department of Insurance's "Safer from Wildfires" program lists ten steps that qualify for discounts, including:

• a Class A roof
• a 5-foot ember-resistant zone, including fencing
• ember- and fire-resistant vents
• 6 inches of noncombustible material at the base of exterior walls
• enclosed eaves
• multi-pane windows
• cleared areas under decks
• moving combustible sheds 30 feet away
• defensible space compliance
• living in a Firewise USA site or a Fire Risk Reduction Community

Step 3. Ask for the three documents up front.

• the defensible space compliance documentation, or the seller's plan for the §1102.19 written agreement
• the §1102.6f fire-hardening notice if the home was built before 2010
• the natural hazard disclosure report

If the seller already has an OCFA or city compliance form, check that it was issued within the last six months.

Step 4. Ask for the HOA's fuel modification records. If the home is in a community with HOA-maintained slopes, ask the HOA for its fuel modification plan, its maintenance schedule and budget, any recent fire authority notices, and whether its reserves or dues cover brush clearing. Read the CC&Rs to see which zones are yours and which belong to the HOA.

Step 5. Walk the first five feet yourself. Use the Zone 0 list as a checklist:

• bark mulch against the house
• wood fences or gates attached to the walls
• firewood stacked by the garage
• plants under eaves or next to vents and windows
• trash under the deck
• leaves in the gutters

Take photos. Most of these are cheap fixes, but they tell you how carefully the home has been maintained.

Step 6. Hire a home inspector who looks at wildfire features. Ask the inspector to report on:

• the roof covering and its rating
• vent screening
• eaves
• window glazing
• the material at the base of the walls
• the deck's material and what's underneath it
• gutter guards
• spark arrestors on chimneys

Step 7. Get bids during your inspection contingency. Get written bids for anything that's missing (vents, gutter covers, a metal section where a fence meets the house, mulch replaced with gravel, brush and tree work). Add them up. That total, not a guess, is what you negotiate with.

Step 8. Decide on a price cut, a credit or a repair (see Illustration 2). Put your request in writing with the bids attached. On a listing that has been on the market longer than the county's 56-day median, or one that has already been reduced, you have more room to ask.

Step 9. If there's no compliance form, put the deadline on your calendar. If you sign the written agreement to get documentation after closing, put the one-year deadline on your calendar the day you close. In OCFA areas, request the free inspection once you own the home. Plan for the work the inspector may require.

Step 10. After closing, plan your Zone 0 upgrades. Even before the rule takes effect, the cheapest steps are worth doing on day one:

• clean the roof and gutters
• move the firewood
• replace bark next to the house with gravel
• clear under the deck
• trim branches away from the roof and chimney

Then plan the bigger items (fence connections, vents, windows) on the three- and five-year schedule, and send your insurer proof of what you've completed.

Mistakes to avoid

• Assuming the old map still applies. The 2025 maps moved zone lines in many cities. Check the current one.
• Treating a handwritten OCFA notice as optional. OCFA doesn't keep copies, so ask the seller for the original. Get bids for every item on it.
• Confusing "not in force" with "doesn't matter." Zone 0 isn't required yet, but insurers and future buyers are already paying attention to it. The 100-foot defensible space law applies now.
• Building a new wood fence or gate within 5 feet of the house. Under the revised text, a new one would have to be noncombustible from the effective date.
• Shopping for insurance at the last minute. Get quotes early in escrow so a coverage problem doesn't delay or cancel your closing.
• Ignoring smoke-damage history. In a neighborhood near a recent fire, ask whether the home had smoke or ash damage, whether a claim was filed, and what cleaning or testing was done.

Quick checklist

• ☐ Fire hazard rating, SRA or LRA, and fire agency confirmed for the address
• ☐ Insurance quotes in hand, with mitigation discounts identified
• ☐ Defensible space compliance form (less than 6 months old) or §1102.19 written agreement
• ☐ §1102.6f fire-hardening notice for homes built before 2010
• ☐ HOA fuel modification plan and budget reviewed
• ☐ First five feet walked and photographed
• ☐ Inspector's report covering roof, vents, eaves, windows, deck and gutters
• ☐ Written bids totaled and used in negotiation
• ☐ One-year compliance deadline calendared (if applicable)
• ☐ Zone 0 to-do list scheduled after closing

What this means day to day

For most Orange County homeowners in a fire zone, wildfire readiness is routine upkeep: clean gutters before Santa Ana wind season, keep a strip of gravel instead of bark along the house, keep firewood away from the walls, and use metal where the fence meets the house. For buyers, these details affect insurance, inspections and resale value. The Norte Fire showed that even homes that survive can lose months to smoke damage and insurance disputes. The best time to find these issues is during escrow, while you can still negotiate.
