California property insurance carries strong consumer-protection timelines, a robust insurer of last resort (the FAIR Plan), and special wildfire rules that constrain when carriers can drop policies. This standalone guide covers the national property fundamentals and then makes California law the spine—cancellation and nonrenewal notice periods, residual markets, and wildfire protections.

The national base: property insurance concepts

Property insurance pays for direct physical loss to buildings and personal property. Core fundamentals tested everywhere:

• Insurable interest — you must stand to suffer a financial loss to collect.
• Indemnity — restore the insured to the pre-loss position, no more.
• Actual Cash Value (ACV) = replacement cost − depreciation; Replacement Cost (RC) pays to rebuild without depreciation (subject to coverage limits and conditions).
• Named-peril vs. open-peril (all-risk) forms — named-peril covers only listed causes; open-peril covers all causes except those excluded.
• Coinsurance — penalizes underinsuring below a required percentage (often 80%) of value.
• Standard exclusions for flood, earth movement (earthquake), war, and ordinary wear.

Proposition 103 and property rates

Like other California P&C lines, property rates fall under Proposition 103: most rates need prior approval by the elected Insurance Commissioner and may not be excessive, inadequate, or unfairly discriminatory. This prior-approval system is central to California's wildfire-market stress, because insurers cannot freely raise rates and have sometimes responded by restricting new business—driving more homeowners to the FAIR Plan.

Cancellation and nonrenewal notice periods

California tightly limits when a property insurer can end coverage:

• Mid-term cancellation of a residential property policy is allowed only for specific reasons—chiefly nonpayment of premium, fraud/material misrepresentation, or a substantial increase in the hazard insured against—once the policy has been in force a set time (commonly 60 days).
• Cancellation notice is short: typically about 10 days for nonpayment and a longer window (often around 30 days) for other permitted reasons.
• Nonrenewal of a residential property policy requires advance written notice—commonly 45 days before the policy expires—and the insurer must state the reason.

Treat the precise day counts as the standard CDI figures; the 45-day residential nonrenewal notice is the one most often tested.

The California FAIR Plan

The California FAIR Plan is the state's property insurer of last resort. Key points:

• It is a syndicated pool of admitted insurers, created so property owners who cannot obtain coverage in the voluntary market—often due to wildfire risk—can still buy basic fire insurance.
• FAIR Plan coverage is limited—historically a basic fire/dwelling form rather than a full homeowners policy—so owners often pair it with a "difference in conditions" (DIC) wraparound for liability, theft, and water damage.
• The FAIR Plan has expanded its limits and offerings in response to the wildfire crisis, but it remains a stopgap, not a substitute for the voluntary market.

Wildfire considerations and nonrenewal moratoriums

Wildfire is the defining California property issue. The Legislature created protections to keep homeowners insured after disasters:

• After the Governor or local authorities declare a wildfire emergency, insurers are barred from cancelling or nonrenewing residential policies in affected areas for a set period—commonly one year from the declaration—even for homes that were damaged.
• California also requires insurers to recognize wildfire-mitigation efforts (defensible space, hardened homes) under the state's "Safer from Wildfires" framework when rating and underwriting.
• Insurers must give policyholders information about coverage and replacement cost so they aren't underinsured after a total loss.

Consumer protections after a loss

• Claim-handling timelines under the Fair Claims Settlement Practices Regulations require the insurer to acknowledge a claim quickly (about 15 days), accept or deny within roughly 40 days of proof, and pay promptly after settlement (about 30 days).
• After a declared disaster, insureds get extended time to collect full replacement cost and to rebuild, plus additional living expense (ALE) protections.
• California has no general "valued policy law" that forces total-loss payment of the full face amount the way some states do; payment follows the policy's valuation (ACV/RC) terms, though total-loss and rebuilding rules add consumer protections.

Key California numbers to memorize

Common exam traps

• Allowing cancellation for any reason. After ~60 days, only nonpayment, fraud, or increased hazard.
• Using the wrong nonrenewal notice. Residential property is commonly 45 days.
• Calling the FAIR Plan a full homeowners policy. It is basic fire, often paired with a DIC.
• Forgetting the wildfire moratorium. After a declared disaster, ~1 year of no cancel/nonrenew in affected areas.
• Assuming California has a valued policy law that pays full face on total loss—it generally does not.
• Ignoring Prop 103. Property rates need prior approval.

Quick recap

California property insurance builds on national fundamentals—insurable interest, indemnity, ACV vs. RC, named vs. open peril, coinsurance—then layers on strong state rules. Rates are Prop 103 prior approval, mid-term cancellation is limited to nonpayment, fraud, or increased hazard after about 60 days, and residential nonrenewal typically requires 45 days' notice with a stated reason. The FAIR Plan is the basic-fire insurer of last resort, usually paired with a DIC policy, and after a declared wildfire disaster insurers generally cannot cancel or nonrenew affected residential policies for about one year. Claim timelines (~15/40/30 days) and wildfire-mitigation credits round out the protections. Master the notice periods, the FAIR Plan, and the wildfire moratorium, and the property-basics section is solid.
