A significant portion of the Santa Cruz Mountains and the hills above Aptos and Soquel fall within Cal Fire’s High or Very High Fire Hazard Severity Zones. Buying in these areas is still common, but the insurance market has changed dramatically since 2020. If you’re looking at a hillside or mountain property, get your insurance quote before you’re in contract — not after.

What happened in 2020

The CZU Lightning Complex Fire ignited in August 2020 and burned approximately 86,500 acres across Santa Cruz and San Mateo counties. It destroyed over 900 structures and forced tens of thousands of evacuations. It was the largest fire in Santa Cruz County’s recorded history.

The fire accelerated what was already happening in the California insurance market. Major carriers were already pulling back from high-risk areas. After CZU, more followed. Several large insurers stopped writing new homeowners policies in California entirely. Others stopped renewing policies in designated fire zones.

The result: homeowners in the hills above Aptos and Soquel and in the San Lorenzo Valley are navigating a genuinely difficult insurance market.

Cal Fire Hazard Severity Zones

Cal Fire designates every parcel in a State Responsibility Area (SRA) with a Fire Hazard Severity Zone (FHSZ) rating: Moderate, High, or Very High. Cities and counties may apply their own ratings to areas under Local Responsibility (LRA).

The ratings are based on fuel load, terrain, weather patterns, and ember exposure. They’re not a prediction that a specific property will burn — they’re a measure of risk conditions.

You can look up any parcel on Cal Fire’s FHSZ viewer at egis.fire.ca.gov/FHSZ. Check this before you make an offer.

What the designation means for buyers

Insurance. A High or Very High designation doesn’t automatically make a property uninsurable, but it limits your options. Some carriers won’t write in those zones at all. Others will, but at higher premiums and with stricter underwriting requirements. Some require specific mitigation measures — ember-resistant vents, Class A roofing, clearance documentation — before they’ll bind coverage.

Get insurance quotes during your contingency period, not after you remove contingencies. If you can’t get coverage at a price that works, that’s a material fact about the property. It also affects your financing options — some lenders won’t close on a property without acceptable hazard coverage in place.

The California FAIR Plan. The FAIR Plan is the state’s insurer of last resort. It provides basic dwelling coverage when standard market coverage isn’t available. It’s better than nothing, but it doesn’t replace a full homeowners policy — it typically doesn’t include personal property, liability, or loss of use coverage. Many buyers in high-risk zones pair a FAIR Plan policy with a separate “difference in conditions” policy to fill the gaps.

Defensible space. California law requires 100 feet of defensible space around structures in State Responsibility Areas. Zone 1 (0–30 feet) requires removal of most flammable vegetation. Zone 2 (30–100 feet) requires reduced fuel load. Inspections are conducted by Cal Fire. Violations can affect insurance and can result in citations.

Home hardening. New construction in High and Very High zones must meet Chapter 7A building standards — ember-resistant vents, multi-pane windows, Class A roofing, and ignition-resistant siding. Older homes built before these standards aren’t required to retrofit, but some insurance carriers require specific upgrades to write a policy.

What to check before you buy

The FHSZ designation. Look it up. Know whether you’re in Moderate, High, or Very High before you fall in love with the property.

The insurance history. Ask for a CLUE report (Comprehensive Loss Underwriting Exchange). This shows prior insurance claims on the property. A history of fire, smoke, or water claims can affect your ability to get coverage or the terms you’re offered.

The roof and vents. A Class A roof and ember-resistant vents are increasingly required by insurers. If the property has wood shake roofing or standard vents, factor in replacement costs.

Defensible space condition. Drive the property. Is the vegetation cleared? Are there overhanging trees near the structure? How close are neighbors’ buildings? A well-cleared property in a fire zone is a different insurance proposition than a heavily wooded one.

Water supply. Some rural parcels rely on private wells or on water systems with limited pressure. Fire agencies consider this when rating properties. If there’s a cistern or fire sprinkler system, that can matter to insurers.

Access. Narrow, single-lane roads with limited turnaround space affect evacuation risk and emergency response. This shows up in insurance underwriting and in your own practical assessment.

The insurance conversation

I’ve watched the insurance market in these hills change substantially since I’ve been here. In the 1990s, you could insure a hillside home in Aptos or Soquel without much difficulty. Today, it’s a real part of the transaction.

That doesn’t mean you shouldn’t buy in a fire zone. People do, every year, and they make it work. But go in with your eyes open. Get three quotes. Understand the FAIR Plan as a backup, not a first choice. And make insurance a contingency item, not an afterthought.

If you’re looking at a property in the hills and you want to talk through the insurance picture, call me. I know the specific neighborhoods and can give you a realistic read before you’re deep in the process. If you’re still in early research mode, the Santa Cruz County buyer’s guide is a good place to start.

Frequently asked questions

What is a Fire Hazard Severity Zone in California?

Cal Fire assigns every parcel in a State Responsibility Area one of three Fire Hazard Severity Zone designations: Moderate, High, or Very High. The designation reflects the fire risk conditions — fuel, terrain, weather — not a certainty of burning. It affects insurance availability, building code requirements for new construction, and defensible space obligations.

Can you get homeowners insurance in a Cal Fire High or Very High zone?

Yes, but your options are limited. Some major carriers no longer write policies in High or Very High zones in California. Smaller regional carriers and surplus lines insurers still do, often at higher premiums. The California FAIR Plan is the insurer of last resort if standard coverage isn’t available. Always get insurance quotes during the inspection contingency period.

What is the California FAIR Plan?

The California FAIR Plan is a state-mandated insurer of last resort that provides basic fire coverage when standard market coverage is unavailable. It typically covers the dwelling structure but not personal property, liability, or additional living expenses. Many homeowners in high-risk zones pair it with a separate “difference in conditions” policy for broader coverage.

What is defensible space in California?

California law requires 100 feet of defensible space around homes in State Responsibility Areas. The inner 30 feet (Zone 1) must be mostly clear of flammable plants and debris. The outer 70 feet (Zone 2) must have reduced vegetation and fuel load. Cal Fire inspects properties and can cite violations. Insurance companies also check compliance when underwriting policies in high-risk zones.

Did the CZU fire affect insurance rates in Santa Cruz County?

Yes. The CZU Lightning Complex Fire in August 2020 burned about 86,500 acres in Santa Cruz and San Mateo counties. Combined with other major California fires, it accelerated the pullback of major insurers from the state. Insurance in the Santa Cruz Mountains and the hills above Aptos has become significantly harder to obtain and more expensive since 2020.
