Short-term rental insurance in Washington state: what your homeowner policy won't cover

Most Seattle property owners who list on Airbnb or VRBO assume their existing homeowner insurance covers them. It almost certainly does not—and the gap is not a technicality. If a guest is injured on your property, or a guest causes significant damage, and your insurer discovers you were operating an undisclosed short-term rental, they can deny the claim entirely and potentially cancel your policy.

Key takeaways

• Standard homeowner insurance (HO-3 policies) excludes coverage for commercial activity, which the IRS—and most insurers—treat short-term rental as.
• Landlord insurance (dwelling fire policies) covers long-term rental activity but typically excludes stays under 30 days.
• Airbnb AirCover for Hosts provides up to $1 million in liability protection and $3 million in property damage protection, but it has significant exclusions and is not a substitute for a standalone insurance policy.
• Washington state has several STR-specific endorsements and standalone policy options from carriers including Proper Insurance, CBIZ, and select Lloyd's of London syndicates.
• The right coverage stack for most Seattle STR owners: an STR-specific policy (or a homeowner policy with an STR endorsement) plus AirCover as a secondary layer.

Why your existing policies don't cover STR activity

Homeowner insurance (HO-3): A standard homeowner policy is written for owner-occupied personal use. When you charge guests for overnight stays, you are conducting a commercial hospitality activity. Most HO-3 policies include an exclusion for "business pursuits" conducted on the premises. STR activity typically falls within this exclusion. Some insurers will add a short-term rental endorsement to an existing HO-3 for an additional premium; others will not write the risk at all and require a separate policy.

Landlord insurance (dwelling fire / DP-3): Landlord policies are written for long-term residential tenancy—typically leases of 12 months. The guest occupancy model of STR (strangers booking for 1–7 nights with no screening beyond Airbnb's ID verification) represents a fundamentally different risk profile than a vetted long-term tenant. Most dwelling fire policies explicitly exclude stays under 30 days.

Renters insurance (if your tenants carry it): Not applicable. Renters insurance covers a tenant's personal property, not the property owner's liability or the structure.

The practical consequence: if a guest slips on your wet deck, breaks their wrist, and files a liability claim against you, your standard HO-3 insurer can deny coverage on the grounds that you were conducting unlicensed commercial activity on a policy that excludes it. If a guest throws a party that results in $40,000 in damage, the same logic applies.

What Airbnb AirCover for Hosts actually covers

Airbnb introduced AirCover for Hosts as a free protection program for all listings on the platform. As of 2026, it includes:

• Host liability insurance: Up to $1 million in coverage for third-party bodily injury or property damage claims arising from a guest stay.
• Host damage protection: Up to $3 million in coverage for guest-caused damage to your property, including damage to the structure, contents, vehicles, boats, and pet damage.

These are meaningful numbers. But AirCover has significant limitations that property owners must understand:

What AirCover does not cover:

• Damage caused by normal wear and tear
• Acts of nature (flooding, earthquake, windstorm)
• Cash, securities, or collectibles
• Shared or common areas not exclusively used for the guest's stay
• Damage caused by the host's own negligence or intentional acts
• Bodily injury to you, your employees, or co-hosts
• Business income loss (if damage renders the property unusable)
• Claims arising from properties not actively listed on Airbnb at the time of the incident

The structural limitation: AirCover is not an insurance policy—it is a contractual protection program between Airbnb and hosts, subject to Airbnb's claims process, Airbnb's determination of fault, and Airbnb's terms of service. Airbnb can and does dispute claims, require documentation, and apply policy limitations in ways that differ from a regulated insurance carrier. AirCover claims are processed by Airbnb, not by an independent insurer with regulatory obligations.

VRBO has a comparable program (Generali Global Assistance) with similar structure and limitations.

STR-specific insurance options for Washington state owners

Several carriers have developed products specifically for the short-term rental market. These are the main options available to Seattle and Washington state STR owners as of 2026:

STR-specific standalone policies

• Proper Insurance: One of the most widely used STR-specific carriers in the U.S. Proper writes a commercial package policy that covers the dwelling, contents, liability, and loss of rental income in a single policy. It is specifically designed to replace both the homeowner and landlord policy for STR operators and is available in Washington state.
• CBIZ STR Insurance: Offers a specialty product written through Lloyd's of London underwriters, targeting STR operators with coverage for property damage, liability, and loss of income. Available in Washington.
• Slice Insurance: A usage-based STR policy that activates on a per-stay basis. Useful for owners who also use the property personally and want coverage that precisely matches the rental period.

Homeowner policy with STR endorsement

Some standard carriers—including certain Farmers, Allstate, and USAA programs—offer STR endorsements that can be added to an existing HO-3 policy, extending coverage to short-term rental activity. Availability varies by underwriter and individual risk factors (property type, annual rental volume, geography). Ask your current carrier whether they offer this option before purchasing a standalone policy.

What to ask any carrier:

• Is the policy written on an "occurrence" or "claims-made" basis? (Occurrence is generally preferable for liability.)
• Does the policy cover loss of rental income if the property is damaged and unrentable?
• Does the policy cover guest-caused damage with a per-incident deductible, or is there a sublimit?
• Does the policy require a minimum lease term, or does it explicitly cover stays under 7 days?
• Is the policy compatible with simultaneously listing on both Airbnb and VRBO?

What a Washington state STR owner should have in place

The coverage structure that makes sense for most Seattle STR owners who operate a dedicated rental property:

1. Primary layer: STR-specific standalone policy (Proper Insurance or equivalent). This replaces the homeowner or landlord policy entirely and covers the dwelling, liability, contents, and loss of income under a single commercial STR contract.
2. Secondary layer: AirCover (Airbnb) and/or Generali (VRBO). These platform protections operate on top of your primary policy for claims arising from platform bookings. They add capacity and provide a secondary avenue for dispute resolution.
3. Optional: umbrella liability policy. For higher-value properties or owners with significant personal net worth to protect, a personal umbrella policy ($1–$5 million) provides liability coverage above and beyond the primary STR policy limits.

For owners who use the property personally and only occasionally rent it out (fewer than 90 days per year), a homeowner endorsement may be more cost-effective than a full standalone policy. Discuss your specific rental volume and personal use pattern with a licensed Washington state insurance broker.

What URPM recommends to owners at onboarding

When URPM takes on a new managed property, insurance verification is part of the onboarding checklist. We confirm that the owner has an active STR-appropriate policy before the listing goes live. If you are not sure whether your current coverage is adequate, we can refer you to Washington-licensed insurance brokers who specialize in STR properties.

Frequently asked questions

If Airbnb AirCover covers up to $3 million in damage, why do I need a separate policy? AirCover is a contractual protection program, not a regulated insurance policy. It is administered by Airbnb, subject to their internal claims process and their sole determination of coverage. A regulated insurance carrier has legal and statutory obligations to handle claims fairly; a platform does not. Additionally, AirCover does not cover acts of nature, normal wear and tear, loss of rental income during repairs, or incidents outside Airbnb-booked stays (such as direct bookings or VRBO stays).

Does my mortgage lender care what insurance I carry? Yes. Most mortgage agreements require the borrower to maintain adequate property insurance. If you switch from a homeowner policy to an STR-specific commercial policy, notify your lender. Some lenders require specific coverage minimums or carrier approvals. Failure to maintain required coverage can technically trigger a mortgage default clause.

What if I only rent occasionally—do I still need STR insurance? Even one paid guest stay creates a commercial activity that your standard HO-3 may exclude. The frequency of rentals does not change the coverage exclusion—it changes the premium calculation. If you rent for any period, discuss the appropriate coverage level with your broker.
