What Is General Liability Insurance?
General liability — often abbreviated CGL for Commercial General Liability — covers your legal exposure to third parties when something at your property causes bodily injury or property damage. The "third party" is anyone who isn't you or your employee, which on a short-term rental almost always means a guest, a member of a guest's group, or a neighbor whose property is damaged by something originating at yours. The Insurance Information Institute describes CGL as the foundation of any business-property liability program — and an STR operator is a business operator the moment the property is listed for nightly rent.
It doesn't pay you when your roof leaks. It pays the guest who slipped on a wet pool deck and broke an ankle, or the neighbor whose fence was damaged when a guest's party got out of hand. It funds the legal defense and the settlement or judgment, up to the policy limit. A typical STR general liability policy carries a per-occurrence limit (the most paid for any single claim), a general aggregate (the most paid across all claims in a policy period), and separate sub-limits for Medical Payments (no-fault first-aid coverage regardless of negligence), Personal & Advertising Injury, and Damage to Premises Rented to You.
Why STR operators need this beyond standard homeowners coverage: nearly every standard homeowners policy excludes commercial use, and short-term rental qualifies as commercial use the moment a guest pays for a stay. A claim during a guest stay can be denied entirely, often paired with a non-renewal letter. The NAIC consumer materials consistently flag that "renting out your home" through a platform changes the policy class — and most homeowners forms simply weren't priced for the resulting exposure.
Premises Liability vs. Guest-Activity Liability
Premises liability is the coverage trigger for claims tied to the condition of the property: a guest slips on icy stairs, falls through a faulty deck railing, or is shocked by a defective outlet. The negligence theory is that you failed to maintain the property in a reasonably safe condition. This is the foundation of any general liability policy and what most STR owners assume is the whole product.
Guest-activity liability — sometimes called hosted-activity or hosted-experience liability — is the coverage trigger for claims tied to activities you provide as part of the rental. If you stock a hot tub, kayak, ATV, or a guided experience like a wine tasting or a fishing trip, the activity itself can generate a claim that isn't tied to the property's physical condition. Many STR policies cover premises liability but exclude or limit hosted-activity exposure unless specifically endorsed.
What to look for: in the policy declarations, confirm that "hosted activities" or "guest-activity exposure" is either included in the named-insured operations or specifically added by endorsement. Hosts who advertise amenities or hosted experiences on Airbnb or VRBO should not assume the premises coverage alone responds when the claim arises from the activity rather than the structure.
