Short-term rental insurance in California: which kind of policy covers what?

A stay of 30 days or less, in the state law that defines the term. Civil Code Section 1748.80, on booking refunds, calls a home, or any portion of it, a short-term rental when it is rented "for 30 or fewer consecutive days."

State law also makes booking sites give a notice to every host who lists a home. The notice tells you to review "any restrictions on coverage" in your own policy. Cities add their own permit rules, set out in which California cities require insurance.

A standard homeowners policy often falls short for hosts. Under the 2011 model form, renting becomes a business when it earns over $2,000 a year. Its liability section keeps covering an "occasional" rental, or part of the home rented to no more than two roomers or boarders.

In 2016, state insurance regulators wrote that homeowners and dwelling policies are "generally not designed" for accidents tied to short-term rentals. The homeowners guide for Airbnb hosts reads that wording line by line.

Three kinds, and the table below shows who each one usually fits. The Insurance Information Institute, known as Triple-I, named similar choices in a March 2026 article: short-term rental add-ons to a homeowners policy, and commercial or rental-specific coverage.

State regulators made the same point in 2016. Coverage "may be available in the form of landlord policies or endorsements to a standard homeowners or dwelling policy," their paper said. An endorsement is an add-on.

A home-sharing add-on changes a homeowners policy for hosting. In 2016, regulators described add-ons from the Insurance Services Office (ISO), the group that drafts standard policy wording, that restore coverage the policy leaves out for hosts.

Those add-ons can widen theft coverage, reach other buildings on the lot and pay lost rental income, the paper says. Insurers charge for them. Some insurers attach the opposite kind, an exclusion that strips theft, vandalism and liability tied to hosting.

Expect limits even with the add-on. Triple-I's March 2026 article tells hosts to follow any restrictions "on number of guests and days or nights for rental use." The guide to home-sharing endorsements sets the two kinds next to each other.

This kind fits best when the home is your own and guests come now and then, or rent a room in the home you live in.

Insurers call a landlord policy a dwelling fire policy. It is written for a home you rent to others. Regulators wrote in 2016 that it covers the building, its fixtures and appliances, and can pay the rent you lose after covered damage.

It comes with less built in than a homeowners policy. Furnishings you leave for guests are typically left out, though they can be added back. Liability and medical payments are often missing as well, and both can be added.

Not every landlord policy allows short stays, so ask before you buy. The FAIR Plan writes such homes under the Seasonal Rental type on its dwelling page, for homes rented out, all or partly, on terms under a year. Its policy has no coverage for a guest's injury or for theft.

For a second home you also use, which policy fits a second home rented some weekends walks through the choice.

It is coverage written for a rental run as a business. Triple-I's March 2026 article lists commercial property insurance, small business insurance and short-term rental coverage among the options for owners.

Policies written for rental properties "may negate the need for a personal dwelling or homeowners policy" on the listed home, regulators wrote in 2016. Ask the agent whether a quote replaces your current policy or sits beside it.

The FAIR Plan used to treat short-term home sharing as commercial. Its 2020 filing said those homes were then written under its commercial program. The Department approved moving them into its dwelling program from January 1, 2021.

A booking site's own host program is not a policy you own, and it has its own limits. Whether AirCover is enough goes through Airbnb's program.

Triple-I's March 2026 advice is to tell your insurer before the rental starts. Put these questions to the insurer or agent, and get the answers in writing:

• Does this policy allow stays of 30 days or less, and is there a limit on nights a year?
• Is a guest who gets hurt covered, and what is the liability limit?
• Is the furniture I provide for guests covered, theft included?
• Does the policy pay for lost bookings while covered damage is repaired?
• Does the policy meet my city's permit rule, if it has one?
• What changes during weeks when my own family uses the home?
