Does homeowners insurance cover Airbnb guests in California?
A homeowners policy may cover an occasional guest, but regular hosting often falls outside it. In 2016, the National Association of Insurance Commissioners wrote that homeowners policies are "generally not designed to cover accidents arising from short-term property rental," except occasional stays. California law also makes booking sites tell every host to check their policy before listing.
The short version
- The 2011 model homeowners form treats paid hosting as a business once it earns over $2,000 in the 12 months before the policy year.
- The 2011 model homeowners form covers a guest's injury if you rent "on an occasional basis" or take in two "roomers or boarders" at most.
- Some insurers add a home-sharing exclusion to the policy, and some offer a home-sharing add-on that gives coverage back.
- Before your first guest, ask your insurer in writing whether your policy covers hosting, and keep the answer.
How does a homeowners policy treat paying guests?
Coverage depends on how often you host and on your policy's own wording. Many insurers build their policies on model forms from the Insurance Services Office, an advisory group. Those forms show the usual rules.
The HO-3 is the model form for a house you live in. Its 2011 edition treats any "activity engaged in for money or other compensation" as a business. Hosting that brings in $2,000 or less in the 12 months before the policy year is an exception.
The form's liability coverage pays when someone is hurt and you are responsible. It excludes injuries "arising out of or in connection with" a business, with two exceptions that matter to hosts.
One exception covers renting your home "on an occasional basis if used only as a residence" at any income. The other covers renting part of your home as a residence, unless your household takes in "more than two roomers or boarders."
Under that wording, the form's liability coverage still applies if a guest trips on your stairs during an occasional stay. It may not when you rent the whole home most weekends. Your own policy may use different words, so read its definitions and exclusions.
What counts as occasional hosting?
No standard definition exists. The 2011 model form uses the word "occasional" without defining it. State insurance regulators wrote in a 2016 paper that the word "is generally not defined" in homeowners policies.
That leaves the line to each insurer. The same paper found that the income limit in business exclusions "varies by policy and can range from $2,000 to $15,000."
"If the insurer deems this activity more than occasional, it may drop coverage for the customer," the paper warned. If an insurer has already acted, California's cancellation and notice rules set what it can do and how fast.
What the model form leaves out when you host
Some gaps apply even to an occasional guest. The 2011 model form excludes theft from the part of your home you rent to someone outside your household.
A guest house or backyard cottage is another gap. The form leaves out other buildings on the lot that are "rented or held for rental to any person not a tenant of the dwelling." The guide to ADU insurance explains what to ask about that gap, and the state's rental rules for ADUs.
Some policies go further with a home-sharing exclusion. The regulators' paper says the Insurance Services Office's version excludes losses from "theft, vandalism, liability coverage and personal injury related to home-sharing activities."
That exclusion has a limit. The paper says it "will not apply to property coverage unrelated to home-sharing, such as coverage for damage from fire, windstorm or hail."
| Occasional stays | Regular paid hosting | |
|---|---|---|
| A guest is hurt and you are responsible | Liability coverage still applies to occasional rentals of your home | Excluded once hosting earns over $2,000 in the 12 months before the policy year, unless you take in no more than two roomers or boarders |
| A guest steals from the room they rent | Not covered: the form excludes theft from the rented part of the home | Not covered, for the same reason |
| A guest cottage you rent out is damaged | Not covered: rented buildings apart from the house are left out | Not covered, for the same reason |
| Your furnishings in a unit of the home you rent out | The form's usual terms apply, except for theft | Limited to $2,500 per unit, and not for theft |
What is a home-sharing add-on?
A home-sharing add-on (insurers call it an endorsement) gives back some of the coverage that hosting takes away. The regulators' paper says the Insurance Services Office's versions can "restore coverage excluded" and "enhance theft coverage."
They can also extend coverage to other buildings on the property and pay for rental income you lose. Not every insurer offers one. Ask whether yours does, and what it adds to your yearly price.
Not every home-sharing endorsement adds coverage, though: the one the FAIR Plan filed in 2020 takes some away.
A home you do not live in is a different case. The 2011 model form covers "the one-family dwelling where you reside," so a house you only rent to guests needs a policy written for a rental. Its terms should allow short stays.
Does AirCover replace your homeowners policy?
No. As of October 28, 2026, Airbnb's AirCover for Hosts includes $3 million of Host damage protection and $1 million of Host liability insurance. Airbnb says the program is "not a substitute for personal insurance," and AirCover applies only to stays booked on Airbnb.
Airbnb also says AirCover's Host damage protection "isn't an insurance policy," and that it does not cover "acts of nature" such as earthquakes. What AirCover covers, and what it leaves out goes through both halves.
What to ask your insurer before your first guest
California law makes booking sites remind you. Right before you list each home, the site must show a notice set by state law and have you confirm you read it. It tells you to "review any restrictions on coverage under your homeowners' or renters' insurance policy related to short-term rental activities."
Cities can add their own insurance rules for short-term rental permits. The city-by-city rules list what each one asks for.
Put these questions to your insurer in writing, and keep the answers with your policy.
- Does my policy cover a guest who is hurt during a paid stay?
- How many nights a year, or how much hosting income, still counts as occasional?
- Does my policy have a home-sharing exclusion, and do you offer a home-sharing add-on?
- Is theft or damage by a guest covered, in the rented room and in the rest of the house?
- Is a guest cottage or backyard unit covered while guests stay there?
- If my city requires proof of insurance for a permit, can you provide it?
Questions people ask us
Does homeowners insurance cover damage caused by an Airbnb guest?
Homeowners coverage for guest damage depends on your policy. The 2011 model HO-3 form excludes theft from the part of your home you rent out, and a home-sharing exclusion can also remove vandalism tied to hosting. Airbnb's AirCover for Hosts may reimburse guest damage when the guest does not pay.
How many nights can I rent on Airbnb before my homeowners policy stops covering me?
No standard number of nights exists. The 2011 model HO-3 form keeps liability coverage for renting "on an occasional basis" but never defines the term. In 2016, state regulators found income limits from $2,000 to $15,000 across policies, so ask your insurer for its own line, in writing.
Should I tell my insurer before I start hosting on Airbnb?
Yes. Hosting can change what a homeowners policy covers, and California law makes booking sites tell hosts to check their policy for limits on short-term rentals. Tell your insurer before the first booking, and keep its answer in writing.
What is a home-sharing endorsement?
A home-sharing endorsement changes how a homeowners policy treats hosting: some versions exclude hosting losses, and others give coverage back. The Insurance Services Office's add-on versions can restore excluded coverage, improve theft coverage, extend coverage to other buildings and pay lost rental income. Not every insurer offers one.
Does homeowners insurance cover a guest cottage I rent on Airbnb?
The 2011 model HO-3 form does not. It leaves out other buildings on the lot that are rented to anyone who is not a tenant of the house. Ask your insurer whether an add-on or a separate policy can cover the cottage.
