Why Home Insurance Won't Cover Your STR

This is the resource that quietly saves operators the most money, because the failure mode is invisible until the worst possible moment: you file a claim, and the insurer discovers you’ve been hosting.

The core problem: hosting is “commercial use”

A standard homeowner’s or tenant’s policy is written for personal use of your home. The moment you accept paying guests, most policies treat that as commercial activity — and commercial activity is typically excluded. Buried in almost every home policy is a “business use” exclusion that does exactly this.

The consequence isn’t just “the Airbnb incident isn’t covered.” If you file a claim and the insurer discovers undisclosed short-term rental activity, they can deny the claim entirely and cancel your policy — sometimes retroactively, meaning no coverage for anything, not just the rental-related loss. There’s a widely-cited case of a host whose six-figure claim was denied after a tree fell on her property — even though no guest was present and the damage had nothing to do with hosting — purely because the policy’s rental exclusion applied once the insurer learned she rented occasionally.

Read that twice: the rental didn’t have to cause the loss. The undisclosed activity alone voided the coverage.

What “AirCover” does and doesn’t do

Airbnb’s AirCover (and similar platform programs) provide some liability protection — commonly up to $1,000,000 USD for a host’s legal responsibility if a guest is injured or their property is damaged. That’s real, but it’s not a substitute for property insurance, and it has significant gaps: it generally doesn’t cover wear and tear, cash, pets, shared or common areas, or undisclosed items. It also only applies to bookings made through that platform — a direct booking isn’t covered.

Important for Ontario operators: where a municipality requires you to carry your own liability policy (commonly $2,000,000) naming STR activity, AirCover does not satisfy that licensing requirement.

What you actually need

Two paths, depending on your insurer:

A short-term rental endorsement added to your existing home policy — an add-on that discloses the rental activity and extends coverage to it. The cleanest option if your insurer offers it, because it keeps everything under one policy.

A dedicated STR / commercial policy that replaces your home or landlord policy. These are purpose-built for the messy reality of an STR: periods of guest occupancy, periods of personal use, and periods of vacancy, all under one policy. They typically cover guest-caused theft, vandalism, and malicious damage (excluded by standard policies), plus loss of rental income if the property becomes uninhabitable.

The non-negotiable: disclose

Whatever you choose, the rule underneath all of it is tell your insurer you’re hosting. An undisclosed STR is the single most expensive mistake in this entire library, because it can erase coverage you’re paying for. Disclosure may raise your premium — that’s the insurer correctly pricing the risk they’re now actually carrying.

The detection discount worth asking about

One upside worth raising with your broker: many insurers offer premium credits for water leak detection and automatic shutoff equipment, because water damage is one of the largest sources of home claims in Canada. The discount is generally for having the equipment — which is its own argument for the monitoring layer. (More on how that works here.)
