What do Lake County's fires and floods mean for your home insurance?

Yes, by a wide margin: in 2022, the FAIR Plan covered 8.4% of the insured homes in Lake County, Department of Insurance data show. California's figure was 3.2%. State law created the Plan for homes that cannot find coverage elsewhere.

The Plan's quarterly count for September 30, 2026, shows 6,089 residential policies in the 13 ZIP codes it files under Lake County. That Lake County total rose 182% from 2,162 on September 30, 2022, and grew again from 5,592 a year earlier, the Plan's five-year file shows.

The same count graded 53% of Lake County's FAIR Plan policies as High in the Plan's wildfire tiers. That tier is the Plan's own grade, not a CAL FIRE hazard zone. Every Lake County ZIP code in the September 30, 2026 file bears a flag the FAIR Plan carries for places where insurance is hard to find.

In 2023, 14.5% of Lake County home policies with insurers other than the FAIR Plan ended in a non-renewal, 3,339 in all, against 8.7% statewide. That count covers every non-renewal, including homeowners who sold a home or switched companies, the Department of Insurance explains. In Lower Lake's ZIP code, 95457, the 2023 rate was 24.5%.

The Valley Fire started on September 12, 2015, in southern Lake County and burned 76,067 acres. On CAL FIRE's record, updated October 24, 2022, it destroyed 1,958 structures, 1,280 of them homes, and killed four civilians.

Three years later came the Mendocino Complex. Its Ranch Fire started July 27, 2018, near Potter Valley and burned 410,203 acres in Colusa, Mendocino, Glenn and Lake counties. Its River Fire, started near Hopland that afternoon, burned another 48,920 acres.

At 459,123 acres, the Mendocino Complex ranks third on CAL FIRE's top 20 list of the state's largest wildfires, dated October 2, 2024. Both fires started in Mendocino County, next door, and burned into Lake County.

The Department of Insurance's Appendix C placed about half of Lake County's dwelling units, 50.2%, at high or very high wildfire risk. That is four times the state's 12.1%, in a weighted average of modelers' scores on homes counted January 1, 2015.

Most of the land the state protects. CAL FIRE's map for that land, in effect since April 1, 2024, puts 360,147 of its 388,659 zoned acres in Lake County in the Very High zone. The 2025 maps for towns and other local land add 15,538 Very High acres, by the State Fire Marshal's acreage table.

In a Very High zone, state law calls for 100 feet of defensible space, a cleared and well-kept buffer around buildings. A seller must also make a natural hazard disclosure, the State Fire Marshal's guide explains.

Your zone does not set your insurance price by itself. The State Fire Marshal's guide calls it "unlikely" that insurers' risk models "specifically call out" the zones, though those models likely use much of the same data. You can look up your own address to see which rules apply to your land.

The Lake County Fire Protection District is the only Lake County agency the Board of Forestry put on its 2026 list of Fire Risk Reduction Communities. The list, which recognizes sound local fire planning, runs from July 1, 2026, until the next one on July 1, 2028.

The FAIR Plan's discount sheet, revised in November 2025, offers a community discount for a home located in a listed community. Discounts are subject to change, the sheet warns. If your home is in Clearlake or elsewhere in the district's area, ask the FAIR Plan whether it qualifies.

Lake County's flood insurance page says it plainly: "Standard homeowners insurance does not cover damage caused by flooding!" Flood coverage is a separate policy, often from the National Flood Insurance Program, in which the county takes part.

Clear Lake rises slowly and reaches flood stage only after long storms, as it did in 1998, the county explains. A flood policy usually has a 30-day wait before it starts, the county adds, so buy it before the rains come.

The wait does not apply to flood insurance bought with a new or changed loan, placed by a lender, or bought after a flood map revision.

A Lake County insurer that won't renew must mail or deliver a notice at least 75 days (90 days beginning January 1, 2028) before your coverage ends. The notice rule also says what the letter has to include.

The Boyles Fire, handled by the Lake County Fire Protection District, burned 81 acres along Dam Road in Clearlake in September 2024. For one year from September 29, 2024, a state moratorium barred insurers from canceling or non-renewing home policies over wildfire risk in four Lake County ZIP codes.

Those were Clearlake's 95422, Clearlake Oaks' 95423, Kelseyville's 95451 and Lower Lake's 95457. That moratorium has ended, and the moratorium guide shows how to check a ZIP code after a new fire.

A FAIR Plan policy is built around fire: smoke damage is in, and wind and hail need an add-on. It would not pay for water from a pipe that bursts while you are away, for stolen belongings, or for a guest who slips on your dock.

A single homeowners policy replacing the FAIR Plan would cover those. If a standard or specialty insurer offers one, you can cancel the FAIR Plan before its term ends once the new policy starts.

Second homes are common around the lake. In Lake County's ZIP codes, 11.3% of housing units were seasonal or occasional-use homes in 2020 to 2024 Census Bureau estimates, against 2.4% statewide. A second home goes through the same Casa questionnaire, with a few extra questions about its use, such as how many months a year it sits empty.

Have these ready for any insurer:

• When the roof went on, and what it is made of.
• Recent, dated pictures of cleared brush and outbuildings.
• Permit dates for any new wiring, plumbing or heating.
• For a home rebuilt after the Valley Fire, its permits and final inspection.
• Your policy's declarations page, the summary of what it covers.
