The California home insurance market has changed dramatically. As a new homeowner here, you need to know things that no lender or real estate agent will tell you — before you close, not after your first claim.
The Basics
A standard California homeowners policy is made up of six distinct coverage parts. Each one matters — and each one has limits and exclusions you need to understand.
By the Numbers
Policy Forms
Most California homeowners have an HO3 policy. The upgrade to HO5 is meaningful — especially for personal property — and often costs less than homeowners expect.
What to Avoid
These aren't rare edge cases. They show up in claims every year — and every one is preventable.
How to Read Your Policy
The declarations page is the single most important page in your home insurance policy. Here's how to read the key numbers — and what red flags to watch for.
California-Specific
Several California-specific laws, risks, and market realities affect your home insurance in ways that don't apply elsewhere.
California's WUI (wildland-urban interface) zones affect millions of homes. Carriers have restricted coverage, added exclusions, or exited entirely. Knowing your fire hazard severity zone (FHSZ) affects your coverage options, premium, and deductible structure.
Check your FHSZ zoneHome insurance does not cover earthquake damage. California residents in seismic zones should consider a separate CEA or private earthquake policy. Also: California building codes require significant seismic upgrades when repairing substantial damage — make sure you have Building Ordinance/Law coverage.
Separate earthquake policy neededCalifornia flooding — historically underestimated — has increased significantly with atmospheric river events. Standard home insurance does not cover flood damage. FEMA's NFIP or private flood insurance is needed for properties in flood zones or low-lying areas.
Home insurance ≠ flood coverageCalifornia's Prop 103 regulates insurance rates and requires DOI approval for increases. Carriers cannot use credit scores for homeowners insurance rating. Rates are based on property characteristics, location, construction, and claims history. This limits some pricing flexibility but also protects consumers from certain rating factors used in other states.
CA law protects youCalifornia law (AB 2369, SB 872) requires insurers to give advance notice before non-renewal. After a declared state of emergency, insurers cannot non-renew policies in affected ZIP codes for one year. These are meaningful protections — but they don't guarantee renewal rates won't increase significantly.
Know your renewal rightsIf admitted market carriers won't write your property, the California FAIR Plan provides fire-only coverage. A Difference in Conditions (DIC) policy must be added alongside it to provide liability, water damage, theft, and loss of use. FAIR Plan + DIC together approximate a standard homeowners policy — but at higher cost.

You need enough dwelling coverage to fully rebuild your home at current local construction costs. In California, this is often different from — and frequently higher than — your purchase price or assessed value, because land value makes up a large portion of a California home's market value. Ask your broker for a Replacement Cost Estimator (RCE) to calculate your actual rebuild cost based on square footage, construction type, and local labor rates.
A standard California homeowners policy (HO3) covers: the dwelling structure (Coverage A) on open perils; personal property (Coverage C) on named perils; personal liability (Coverage E); additional living expenses (Coverage D) if you're displaced; other structures (Coverage B); and medical payments to others (Coverage F). Important exclusions include earthquake, flood, and sometimes wildfire in restricted zones.
Standard homeowners policies include fire coverage — which includes wildfire. However, some carriers have added wildfire exclusions for properties in high-risk WUI zones, and many major carriers have stopped writing new policies in certain California ZIP codes entirely. If you're in or near a wildfire zone, explicitly confirm with your broker that wildfire is covered and is not subject to an exclusion or percentage deductible you weren't aware of.
An independent broker like Bollinsure works for you — not for any single insurance company. We compare policies from 350+ carriers simultaneously to find the best combination of coverage and price for your specific property and situation. A captive agent (like a State Farm or Allstate agent) can only offer you that company's products. In California's current market, where carrier availability varies dramatically by ZIP code, an independent broker's market access is especially valuable.
No. Your lender requires enough insurance to protect the lender's interest in the property — roughly the loan balance. This has nothing to do with your financial protection. The lender doesn't care if your contents are covered, if you have liability coverage, or if you can afford to live somewhere else for 20 months while your home is rebuilt. Lender-minimum coverage is often 40–60% of what a homeowner actually needs.
California home insurance premiums are based on: the insured value of your home (dwelling limit), your home's location and wildfire hazard zone, construction type (wood frame vs masonry), age of roof and major systems, your prior claims history, and the coverage options and limits you select. Under Proposition 103, California insurers cannot use credit score as a rating factor for homeowners insurance — a consumer protection that differs from most other states.
