If you own a home in Orange County — especially in places like San Clemente, Laguna Beach, San Juan Capistrano or Rancho Santa Margarita areas—there’s something new you should know: CAL FIRE has released updated wildfire hazard maps, and the changes could impact your home more than you might expect.
According to a March 2025 report from CalMatters, these newly released maps identify over 6.2 million acres as “very high fire hazard severity zones.” These updates reflect growing concern about wildfire risks in both coastal and inland communities, driven by worsening drought, heat, and wind conditions across the state.
You can view the updated map from CAL FIRE here.
What Changed in the New Fire Maps?
- Expanded High-Risk Zones: Many areas that previously weren’t considered at high risk are now labeled as very high fire hazard zones.
- Local Impacts: These designations affect building codes, home insurance rates, and defensible space requirements.
- Wildfire Behavior: CAL FIRE used updated modeling to reflect today’s more aggressive fire behavior and longer fire seasons.
Whether or not your home has ever faced wildfire before, the new maps make one thing clear: everyone needs to be more prepared.
How to Protect Your Home from Wildfire in Orange County, California
At Rhino Shield of Southern California, we live and work in this community, and we know that wildfire preparedness is more than a checkbox. Here are several smart, proactive steps you can take:
1. Create Defensible Space
- Remove dry brush, dead plants, and flammable materials at least 30 feet around your home.
- Trim tree branches and keep gutters free of debris.
2. Upgrade to Fire-Resistant Building Materials
- Use Class A-rated roofing and non-combustible siding.
- Replace old wood fencing and decks with fire-rated alternatives.
3. Apply a Fire-Rated Exterior Coating
- Apply Class A fire-rated coatings over approved substrates.
- This means the exterior of your home has an added layer of defense against radiant heat and ember attack.
4. Seal Vents and Gaps
- Use fire-rated vent covers or ember-resistant mesh to keep embers from entering attics and crawlspaces.
5. Know Your Zone
- Check your property’s designation using CAL FIRE’s interactive map.
- If you’re in a very high fire hazard zone, you may be subject to additional building and maintenance requirements.
