A single windblown ember can start a house fire in seconds. If you live in Irvine or plan to sell here, you want comfort, safety, and a smooth transaction. Defensible space gives you all three by lowering wildfire risk and helping you meet sale requirements. In this guide, you’ll learn Irvine’s rules, how AB 38 inspections work, and the simple steps that make your home more resilient. Let’s dive in.
Defensible space in Irvine: what and why
Defensible space is the maintained buffer around your home that slows flames and blocks embers. It is California’s first line of defense for structures, with proven benefits for you and for firefighter safety. See the state’s plain-language overview of zones and actions in CAL FIRE’s defensible space guide.
California law sets a baseline expectation of up to 100 feet of defensible space, or to your property line, with stricter fuel reduction closest to the house. You can read the statutory language in Public Resources Code §4291. These measures reduce home ignitions and improve survivability during a wildfire.
Maps that categorize wildfire hazard are being updated statewide. The Office of the State Fire Marshal has released new Fire Hazard Severity Zone information for cities to adopt. Check the official overview of Fire Hazard Severity Zones and Irvine’s page on new map adoption to see how updates may affect your address.
What sellers and buyers must know in Irvine
AB 38 defensible-space disclosure at sale
If a property is in a mapped High or Very High Fire Hazard Severity Zone, the seller must provide documentation that the home meets defensible-space requirements, or the parties can agree in writing that the buyer will obtain it within one year after closing. In Irvine, the Orange County Fire Authority (OCFA) handles these inspections and issues the compliance form used in escrow. Request an appointment through the OCFA inspection request portal. OCFA notes that compliance forms are currently valid for about 6 months.
How to check if your home is in a mapped zone
Because Irvine is in the 2024–2025 map update cycle, your disclosure requirements may change. Review the state’s hazard zone information and the City’s FHSZ update page to verify your address and stay current on local adoption.
HOAs and shared open space
In many Irvine neighborhoods, HOAs maintain common slopes and fuel-mod zones. OCFA inspectors consider HOA-maintained areas during their review, but legal responsibility follows your CC&Rs and contracts. For clarity on how inspectors evaluate parcels and common areas, see the OCFA Ready, Set, Go! FAQ.
Your defensible-space plan, zone by zone
Immediate area: 0–5 feet (ember-resistant)
- Keep this perimeter completely noncombustible where possible. Avoid mulch against walls and do not store firewood or combustible items next to the house.
- Clean roofs and gutters regularly so leaves and needles do not collect.
- Install ember-resistant vent screens and close or box eaves to block embers.
Zone 1: 0–30 feet (lean, clean, green)
- Remove dead or dry plants and debris. Keep shrubs and trees separated so fire cannot ladder from ground to canopy.
- Prune branches to reduce contact and create spacing where appropriate. Clear leaves and needles from yards and decks.
- Keep woodpiles at least 10 feet from structures.
Zone 2: 30–100 feet (or to property line)
- Mow grasses to about 4 inches and thin dense shrubs to reduce continuous fuels.
- Remove accumulated dead material and maintain spacing between trees and shrubs.
- Keep a 10-foot clearance around outbuildings and propane tanks.

Home hardening that pays off
Some upgrades sharply cut ember risk and may qualify you for insurance discounts. High-impact measures include a Class A roof, boxed-in eaves, ember-resistant vents, dual- or tempered-pane windows, and noncombustible siding near the ground. California’s “Safer from Wildfires” initiative requires insurers to recognize mitigation in pricing, but programs vary by carrier. Learn more from the California Department of Insurance and keep photos and receipts of completed work.
Smart planting and easy maintenance in Irvine
Plant selection and upkeep matter. Choose low-fuel, well-irrigated species near the home and maintain spacing between plants and trees. Remember that “fire-resistant” does not mean “fire-proof.” For water-wise, fire-wise landscaping ideas, see this practical guide from California Water Service.
Build a simple rhythm:
- Spring: remove dead annuals, clean gutters and roofs, and prune to eliminate ladder fuels.
- Early summer: mow grasses, check under decks, and clear around propane tanks.
- Mid season: recheck the 0–5-foot zone and sweep decks and patios.
- Fall: clear new debris and schedule any needed tree work.
Irvine resources and next steps
Schedule an AB 38/Defensible Space Disclosure inspection
If your home is in a High or Very High zone and within OCFA jurisdiction, request an inspection at no cost through the OCFA portal. If you cannot complete it before closing, the buyer and seller can sign an agreement for the buyer to obtain compliance documentation within one year.
Stay current on maps and city efforts
Follow Irvine’s updates on FHSZ map adoption and state hazard zone information. City-led fuel-reduction and open-space restoration projects contribute to neighborhood resilience and complement what you do at home.
Sign up for local alerts
Register for Orange County’s emergency notifications so you receive timely wildfire and evacuation updates. You can sign up via AlertOC. Also review family evacuation plans using Ready, Set, Go! guidance from OCFA.
For sellers: 30-day pre-list checklist

- Walk the 0–5-foot zone and remove combustibles. Clean the roof, gutters, and under-deck areas.
- Tidy Zone 1 and Zone 2: cut grasses, prune for spacing, and clear dead material. Photograph before-and-after work.
- If eligible, request an OCFA Defensible Space Disclosure inspection through the inspection portal. Track that the compliance form is current for escrow.
