Why is home insurance so hard to find in Mariposa County?

The California FAIR Plan counted 3,618 residential policies in the eight ZIP codes it assigns to Mariposa County on September 30, 2026. The town of Mariposa's 95338 held 2,093 of them, more than half.

The Plan's five-year file puts the same eight ZIP codes at 2,475 on September 30, 2022, so Mariposa County's count rose 46%. Fish Camp's 93623 is one of the eight, and the guide to Oakhurst and eastern Madera County counts it too.

Mariposa County's FAIR Plan policies sit mostly in the Plan's High wildfire tier: 92% of them on September 30, 2026. Every one of Mariposa County's eight ZIP codes also bears a flag the FAIR Plan carries, its distressed-area marker, in the file dated September 30, 2026.

For 2022, the California Department of Insurance put the FAIR Plan's share of Mariposa County's insured homes at 31.9%. Across California it was 3.2%.

Insurers other than the FAIR Plan renewed 4,098 home policies across Mariposa County's ZIP codes in 2023 and wrote 130 new ones, the Department's data show. That same year, 520 of their Mariposa County policies were non-renewed, 11.0% against 8.7% statewide, a total that includes owners who sold or switched insurers.

The Oak Fire started on July 22, 2022, at Highway 140 and Carstens Road, near Midpines. CAL FIRE's incident page, last updated June 16, 2023, puts it at 19,244 acres and does not count the homes lost.

A day later, on July 23, 2022, Mariposa County came under a state of emergency declared by the Governor. The law then barred insurers, for one year from that date, from cancelling or non-renewing homes in nearby ZIP codes because of wildfire risk.

The Department of Insurance's Bulletin 2022-9 named the ZIP codes. It listed seven of the eight on this page and left out La Grange's 95329.

A later bar, after the TCU September Lightning Complex, covered Coulterville's 95311 and La Grange's 95329 for one year from September 19, 2025. Each bar ends on its own date, so check your ZIP code after any new fire.

Earlier, the Detwiler Fire started July 16, 2017, two miles east of Lake McClure. CAL FIRE's page, last updated October 24, 2022, counts 81,826 acres and 134 structures destroyed.

The Ferguson Fire followed on July 13, 2018, starting at Highway 140 and Hite Cove, near El Portal. It burned 96,901 acres, by CAL FIRE's page, last updated January 4, 2019, with no tally of homes lost.

Averaging catastrophe modelers' scores, the Department of Insurance put 66.9% of Mariposa County's homes at high or very high wildfire risk. Statewide, the figure was 12.1%.

That estimate counts homes as of January 1, 2015. Only Tuolumne, Trinity and Nevada counties ranked higher. Tuolumne, next door, has its own guide with Calaveras County.

The forest adds to the risk. The Oak Fire's federal incident page lists heavy ground fuels from the 2015 and 2016 tree die-off, beetle kill, among the fuels involved.

Two Mariposa agencies, the County of Mariposa and the Mariposa Resource Conservation District, are named among California's Fire Risk Reduction Communities for 2026. The Board of Forestry and Fire Protection names agencies to that roster when their fire planning meets its best practices. This edition runs from July 1, 2026, to July 1, 2028.

The FAIR Plan offers a community discount too, on its wildfire discount sheet for policies dated November 15, 2025, or later. The sheet ties it to a home inside a listed community or a Firewise USA site that is in good standing. Ask your broker whether your address counts, since the sheet says discounts can change.

Renting a whole home to visitors is usually allowed, with the county's approval, but check your insurance first. Mariposa County treats a whole home rented for less than 31 days as a vacation rental. In Wawona, the National Park Service must approve one too, and none are allowed at the park-owned El Portal Administrative Site.

The county's planning department limits a vacation rental to 10 guests and three guest bedrooms, and it allows no more than two short-stay units per parcel.

Before approval, the county's Building, Fire and Planning departments inspect the house. Each year by April 30, the owner confirms that the smoke alarms, carbon monoxide detectors and fire extinguishers work.

Buyers should know one more rule. When a permitted rental home changes owners, its certificate becomes void, and the new owner applies again with full fees and inspections.

Insurance is a separate question. A homeowners policy may not cover paying guests, so put that question to your insurer in writing before you take a booking. How a homeowners policy treats short stays lists what to ask.

About 11% of housing units in Mariposa County's ZIP codes are vacation or second homes, by the Census Bureau's survey for 2020 to 2024. California's share is 2.4%. Casa asks about a second or seasonal home in the same questionnaire, adding a few questions about how it is used, such as short stays.

If the FAIR Plan insures your Mariposa County home, learn its gaps first. The Plan pays for fire and smoke damage, and for wind and hail only as add-ons. It does not pay for a burglary, water from a burst pipe or a guest's fall, and that last gap matters for a home rented to park visitors.

Those three gaps are why a single policy that covers them, replacing the FAIR Plan, is the better fix. The FAIR Plan calls itself an insurer of last resort, so try a standard insurer before a specialty one.

If one says yes, cancel the FAIR Plan only after the new policy starts, as the mid-term switch explains. Then build the file insurers ask for. Gather these:

• When the roof went on, what it is made of, and any receipt or permit.
• Photos showing the brush you cleared around the house, with the dates you took them.
• Update years for the wiring, plumbing and heating.
• Any claims on the home in the last five years.
• If you rent to visitors, your county certificate and the weeks you rent.
