Beyond standard homeowners and dwelling policies, California relies on several specialized property programs to cover the catastrophes that standard policies exclude—earthquake (CEA), wildfire/last-resort fire (FAIR Plan), and flood. This standalone guide reviews the national "other property" fundamentals and then makes California's specialized coverages the spine, since these programs are uniquely important here.

The national base: why "other" property coverages exist

Standard property policies exclude the biggest catastrophe perils—flood, earthquake/earth movement, and (in stressed markets) hard-to-place fire risk. To fill these gaps, insureds buy:

• Separate catastrophe policies (earthquake, flood),
• Residual-market / last-resort coverage when the voluntary market won't write the risk, and
• Wraparound policies (difference-in-conditions) to add perils a basic policy omits.

California's geography—faults, coastline, and wildland-urban interface—makes each of these central rather than optional.

Earthquake: the California Earthquake Authority (CEA)

Because homeowners policies exclude earthquake, California addresses the peril two ways:

• Mandatory offer. Insurers writing residential property must offer earthquake coverage and re-offer it about every other year to homeowners who declined.
• The CEA. Most residential earthquake coverage is written through the California Earthquake Authority, a publicly managed, privately funded pool. Member insurers sell CEA policies alongside their homeowners policies.
• Structure. CEA coverage carries its own percentage deductible (a share of the dwelling limit) and separate limits for the dwelling, contents, and loss of use. Purchase remains voluntary—the homeowner can decline the offer.

Wildfire and the FAIR Plan

The California FAIR Plan is the insurer of last resort for property—especially fire and wildfire risk:

• It is a syndicated pool of admitted insurers that provides basic fire/property coverage to owners who cannot find coverage voluntarily.
• FAIR Plan coverage is limited (historically a basic dwelling/fire form), so insureds typically add a difference-in-conditions (DIC) policy from a voluntary carrier to cover liability, theft, water damage, and other perils the FAIR Plan omits.
• After declared wildfire disasters, statewide rules bar insurers from cancelling or nonrenewing affected residential policies for about one year, and California requires wildfire-mitigation credits under "Safer from Wildfires."

Flood: the NFIP and private flood

Flood is excluded from standard property policies nationwide, and California is no exception:

• Most flood coverage comes from the federal National Flood Insurance Program (NFIP), sold through participating insurers and agents.
• The NFIP imposes a standard 30-day waiting period before a new policy takes effect (with limited exceptions), so coverage can't be bought the day a storm threatens.
• Private flood insurance is a growing alternative. California's coastal, riverine, and post-wildfire debris-flow/mudflow exposures make flood a real concern even away from the coast.

Other specialized property programs

• Difference-in-Conditions (DIC) — broadens or fills gaps left by a basic policy (often paired with the FAIR Plan), and can add earthquake and flood for commercial risks.
• Builders risk / course of construction — for structures being built or rebuilt, common after wildfire losses.
• Inland marine / floater policies — for valuables and mobile property.
• California FAIR Plan commercial options exist for some business property that can't be placed voluntarily.

Regulation tying it together

All of these operate under California's regulatory framework: the elected Insurance Commissioner, Proposition 103 prior-approval rates (which contribute to availability pressures), and the Fair Claims Settlement Practices timelines (~15/40/30 days to acknowledge/decide/pay). The CEA and FAIR Plan are creatures of California statute, while the NFIP is federal.

Key California numbers to memorize

Common exam traps

• Thinking earthquake/flood are covered by HO/DP. Both are excluded and bought separately.
• Calling the CEA offer one-time. Insurers must re-offer about every other year.
• Treating the FAIR Plan as full coverage. It is basic fire, usually paired with a DIC.
• Forgetting the NFIP 30-day waiting period. Flood coverage isn't immediate.
• Confusing federal vs. state programs. NFIP is federal; CEA and FAIR Plan are California.
• Ignoring post-wildfire flood/mudflow risk, a real California exposure.

Quick recap

California's specialized property coverages exist because standard policies exclude flood and earthquake and the voluntary market sometimes won't write wildfire risk. Earthquake is handled by a mandatory offer and the CEA (percentage deductible; purchase voluntary, re-offered about every other year). The FAIR Plan is the basic-fire insurer of last resort, usually paired with a DIC for omitted perils, and after a declared wildfire disaster insurers generally cannot cancel or nonrenew affected policies for about one year. Flood comes from the federal NFIP (with a ~30-day waiting period) or growing private options, with post-wildfire mudflow a unique concern. Everything sits under the elected Commissioner, Prop 103 prior approval, and standard claim timelines. Keep "CEA = earthquake, FAIR Plan = last-resort fire, NFIP = federal flood" straight, and the other-property section is locked in.
