New California Fire Hazard Maps Could Impact Homeowners in Upland.

New Fire Hazard Maps Could Impact Homeowners in Upland—Here’s What You Need to Know
By Councilmember James Breitling

Earlier today, CAL FIRE released its final round of updated Fire Hazard Severity Zone maps—the first local update we’ve seen in over a decade. And yes, this directly impacts many Upland neighborhoods.

The numbers are striking: since 2011, the land in California designated as “High” or “Very High” fire hazard has grown by 168%, now covering more than 3,600 square miles and affecting roughly 3.7 million Californians. Portions of north and northeast Upland—especially in the foothill areas—are now officially included in these expanded zones.

It’s important to understand:
These maps are based on long-term wildfire risk factors—topography, vegetation, and local climate—not on whether you’ve cleared brush or installed a fire-resistant roof. They’re meant to show how likely an area is to burn, not how well an individual property is maintained.

What does this mean for Upland homeowners?

1. New construction in hazard zones must now comply with stricter fire-resistant building codes.

2. Home sales in these areas must include formal disclosure of the fire hazard designation.

3. Property owners in “Very High” zones are required to maintain at least 100 feet of defensible space—clearing brush, dead trees, and flammable debris.

While the state maps don’t directly control insurance policies, they do reflect the same risk factors insurance companies already use. That means we could see higher premiums or more limited policy options in affected areas—something many Californians are already grappling with.

There’s also the impact on home values. A 2023 study found that homes within hazard zones that are subject to disclosure requirements sold for 4.3% less on average than similar properties just outside those zones. That’s a real cost for families trying to sell or relocate.

What happens next?

Local governments are required to accept 90 days of public comment, but under state law, we cannot remove any areas flagged by CAL FIRE. We are, however, allowed to propose additions if needed.

With the release of the news maps I will work with city staff and with San Bernardino County Fire to host a community workshop to what the changes mean and how they can impact you.

If you have questions, please contact me. I may not have an answer but am happy to work with you to find one.
