Short-Term Rentals: What Hosting Does to Your Policy

The listing takes twenty minutes; the insurance implications last as long as the bookings do. Paying guests turn parts of your homeowners policy off — the business-activity exclusions are older than the platforms — and the fix depends on which kind of host you actually are.

Why HO-3s balk at hosting

Two ancient exclusions do the work. Business activity: renting for money is business, and an HO-3's liability coverage largely stands down for business arising on the premises — the guest who slips on your stairs mid-booking is a business claim. Property used by roomers/boarders: contents and some property coverages narrow when paying occupants are involved, and theft-by-guest is a classic gap. None of this requires a platform; it's the money that matters. What the platforms added is scale — and a paper trail that makes "I occasionally host" visible to everyone, including claims adjusters.

Which host are you? Three lanes

PatternThe insurance answer
Occasional — a few stays a year in your primary homeSome carriers tolerate with disclosure; a home-sharing endorsement (where offered) restores liability and guest-related gaps for hosting periods
Regular — a dedicated room/ADU, steady bookingsEndorsements strain; carriers differ sharply. Expect underwriting questions and a possible market change — this is the lane where honest conversations with a broker pay most
Dedicated STR — a property that exists to hostNot a homeowners risk at all: a DP-3-based or STR-specific policy with commercial-style liability, fair rental value, and guest-damage handling

The dividing question isn't the platform or the ZIP code — it's occupancy and intent, the same axis our wizard asks about directly (owner/tenant, primary/seasonal, rental). Answer with the real pattern and the routing takes care of itself. Where HO-3 ends and DP-3 begins →

About platform "host protection"

Platform programs provide real but bounded protection — their terms, their triggers, their exclusions, and no coverage for your own home's non-hosting life. Treat them as a supplement riding above your own properly-structured policy, never as the policy. That's not a criticism of the platforms; it's what their own terms say.

The disclosure math

Hosting quietly on an undisclosed HO-3 saves a modest endorsement premium and bets the house on nothing going wrong during a booking — a guest injury claim that surfaces the listing history is exactly how "misrepresentation" ends up in a denial letter. Disclosed, the outcomes are all workable: an endorsement, a market change, or a proper STR policy whose cost the bookings themselves usually carry. While you're structuring it, extend the thinking one layer up: an umbrella for the household (confirm it addresses hosting — many exclude business exposure too), and if the STR is a real business over time, entity and tax questions belong with your CPA and attorney — we'll stay in the insurance lane.

Frequently asked

I host one week a year during the tournament. Really an issue?

It's the classic occasional case — and still worth the disclosure call, because one week is all a slip-and-fall needs. Many carriers handle exactly this gracefully with an endorsement or a shrug; what none handle gracefully is surprise.

Does hosting an ADU change my main-house policy?

Yes — a rented ADU mixes rental exposure into an owner-occupied parcel. Solutions exist (endorsements, split structures on the policy), and the Coverage B implications are part of the same conversation.

What about mid-term rentals — a travel nurse for three months?

Sustained single-tenant stays look more like tenancy than hosting; carriers often treat them under landlord logic. Describe the arrangement and let the form follow the facts. The landlord guide →
