Why Your HO-3 Doesn't Cover Airbnb
A standard HO-3 homeowners policy is written for a property occupied by its owner for personal residential use. The moment you rent that property to a guest — even for a single weekend — you are using it for commercial purposes. Most HO-3 policies contain business pursuit exclusions that explicitly remove coverage when the property is operated as a rental business. Short-term rental activity through platforms like Airbnb and VRBO is classified as a business pursuit by most carriers.
Some HO-3 policies include a limited provision for "incidental rentals" — occasional, infrequent rental of a room or the whole home. But the threshold for what qualifies as incidental is typically very low, and regular STR activity well exceeds it. If you file a claim after a guest damages the property or is injured on the premises, the carrier's adjuster will review your rental history. Documented STR activity during or before the loss period is grounds for claim denial under the business pursuit exclusion. This is not hypothetical — it is a documented and recurring claim denial reason for California STR hosts.
AirCover Is Not Insurance — Here's What It Actually Is
Airbnb's AirCover program is frequently misunderstood as an insurance policy. It is not. AirCover is a guarantee program administered by Airbnb, not an insurance contract regulated by the California Department of Insurance. It has no policy number, no coverage territory in the traditional insurance sense, and no independent claims process — all claims run through Airbnb's internal resolution system.
AirCover covers certain categories of guest-caused property damage and includes a liability guarantee for host legal expenses. But the exclusions are extensive: cash and securities, jewelry and art, vehicles, property in shared spaces of the host's home, damage that existed before the reservation, and damage discovered after Airbnb's reporting window closes. More critically, AirCover provides no coverage for fire, theft by non-guests, weather events, or vandalism when there is no active reservation. It also provides no loss of rental income coverage if the property is uninhabitable for weeks or months after a covered event.
VRBO's host protection program has similar structure and similar limitations. Platform guarantee programs are designed to resolve guest disputes quickly — they are not designed to replace the structural protection that a real insurance policy provides.
What a Purpose-Built STR Policy Actually Covers
Specialty STR insurance — offered by carriers like Proper Insurance and others operating in California's surplus lines market — is built from the ground up for short-term rental use. It covers the dwelling structure on an open-perils basis with no homeowner-occupancy assumptions, the furnishings and contents you provide to guests, premises liability for guest injuries anywhere on the property, and loss of rental income when a covered event renders the property uninhabitable.
Quality STR policies also include coverage for guest belongings claims (when guests claim their personal property was damaged during a stay), bed bug and vermin remediation, and identity theft protection for the host. Liability limits of $1 million per occurrence are standard, which is a meaningful difference from the $100,000 to $300,000 limits on a typical HO-3's liability section — relevant when a guest sustains a serious injury on the property.
California-Specific Complications: Regulations and Wildfire Zones
California has one of the most fragmented STR regulatory environments in the country. Los Angeles requires that STRs be the host's primary residence and caps rental days for non-primary properties. San Francisco limits non-hosted STR rentals to 90 days per year. Santa Monica effectively bans whole-home STRs outside of very specific categories. Palm Springs and many Napa Valley jurisdictions have their own permit requirements. Operating without required permits creates an illegal-use exposure that some carriers will decline to insure — and that a claims adjuster may use to deny a claim even under a specialty STR policy.
Wildfire zone properties add another layer of complexity. Many admitted carriers will not write STR policies in high-risk fire zones at all. Surplus lines carriers operate more flexibly, but premiums in fire-risk areas reflect the exposure. For California STR hosts in wildfire zones who cannot access private market coverage, the California FAIR Plan covers the structure for fire only — a DIC (Difference in Conditions) policy layered on top adds liability, contents, and loss of rental income. A review with Taylor Arvayo, CPCU, CIC will identify which markets are available for your specific address and operating model.
STR vs. Long-Term Rental: Choosing the Right Coverage
If your property operates as both a short-term rental and a long-term rental at different times of the year, or if you are deciding which model to pursue, the insurance implications matter. Long-term rentals (30+ day tenancies) can typically be covered by a standard DP-3 landlord policy at lower premiums. Short-term rental policies carry higher premiums that reflect the higher frequency of guest turnover, higher contents risk, and greater liability exposure from multiple unrelated guests occupying the property throughout the year.
STR insurance premiums in California typically range from $1,500 to $5,000 per year for a standard single-family home in a non-wildfire zone, depending on the property's size, location, occupancy type, and coverage structure. Wildfire zone properties command higher premiums. The right structure depends on your specific operating model — part-time host, full-time host, owner-occupied with guest rooms, or dedicated investment property.
