Short-Term Rental Insurance: What It Covers and the Gaps

TL;DR: Standard homeowner policies exclude business-pursuit activity, which means most paid STR stays are uncovered if the carrier finds out. Airbnb’s AirCover is a guest-damage guarantee plus a $1M liability policy, not a building or business-income policy. Dedicated STR insurance (Proper, Safely, Steadily and similar) closes the gap, but the exclusions every operator should read before signing are the ones that bite after a claim.

The business-use exclusion most operators do not read

Most US standard homeowner policies (HO-3 forms) treat regular rental activity as a business pursuit, and business pursuits are excluded from base coverage. The exclusion is not new and not specific to short-term rentals, but it is what catches operators who think their existing policy covers them because they “told the carrier.”

What the exclusion does in practice: if a fire, guest injury, or theft claim is filed and the carrier’s investigation finds short-term rental activity, the claim is commonly denied. The policy is also frequently non-renewed at the next term. The carrier may seek to recover claim payments already made if the activity was undisclosed.

Carriers handle disclosure three ways. Some offer a dedicated STR endorsement on the existing HO policy. Some require the operator to switch to a landlord (DP-3) or commercial policy with rental-use language. Some carriers exclude STR activity outright and decline to renew once it is disclosed. The right answer is to ask in writing, get the response in writing, and keep both.

The audience that misreads this most is the operator running two or three short-term rentals on a single homeowner-style policy obtained for a primary residence converted to a rental. The premium feels right and the property looks insured. The claim experience reveals that it was not.

What “STR insurance” actually means: four layers

For a US-based operator, the actual coverage stack has four layers, and most operators are running on one or two when they should be running on three or four.

Layer 1: a policy on the building that explicitly allows short-term rental use. This is either an STR-endorsed HO policy, a landlord DP-3 with STR language, or a dedicated STR policy. Without this, your structure is uncovered for paid stays.

Layer 2: liability insurance with a commercially appropriate limit. This sits inside the Layer 1 policy or is bought separately. STR-specific carriers typically write $1M to $2M per occurrence, with options to extend higher via excess layers.

Layer 3: platform programs. Airbnb’s Host Damage Protection and Host Liability Insurance, plus the equivalent Vrbo programs. These are real and useful, but they have material exclusions and they pay secondary to your own policy on damage claims.

Layer 4: a commercial umbrella. Once your portfolio passes a few doors or your personal asset exposure is significant, a $1M to $5M umbrella above the underlying policies is the cheapest way to push the limits where they should be.

The mistake that produces most uncovered claims is treating Layer 3 as a substitute for Layer 1 or Layer 2. Platform programs are designed to sit on top of your real insurance, not replace it.

What AirCover actually is (and what it is not)

Airbnb’s AirCover for Hosts is the program most operators reference when they say “Airbnb insures me.” The product is two distinct components with different legal natures and limits.

Host Damage Protection. Per Airbnb’s Host Damage Protection Terms (analysed June 2026), this is not insurance. Section 2.5 states: “These Host Damage Protection Terms are not an insurance contract. The Host Damage Protection guarantee is not insurance or an offer to insure.” The cap is $3M per Airbnb stay (Section 6.4.2). It covers physical damage to eligible property by guests or invitees, pet damage, additional cleaning costs for stains, smoke odor removal when the guest violated house rules, and lost booking income from cancellations due to damage.

The exclusions that matter most for operators: damage occurring after guest checkout, acts of nature (earthquakes, hurricanes), mold/mildew/fungus, household linens (with limited exceptions), fine arts that cannot be replaced “like kind and quality”, and any host fraud or dishonest conduct. Section 7.4 confirms the payment is reduced by anything already paid from another source, including the host’s own insurance, which means it is secondary on a damage claim.

Host Liability Insurance. This is real insurance with a $1M limit (analysed June 2026). It covers bodily injury to a guest or others, damage to or theft of property belonging to a guest, and damage caused by guests to common areas or nearby properties. Exclusions include damage from intentional acts and damage to the host’s own property already handled by Host Damage Protection.

The operator-relevant gaps in AirCover, even with both components active:

• Building damage from a non-guest cause (fire spreading from a neighbor, plumbing failure, storm) is not covered. That is a building-policy claim.
• Loss of rental income beyond what a guest specifically caused is not covered. That is business-income coverage.
• Acts of nature are excluded across both components. Hurricanes, earthquakes, wildfires, and floods need separate policies.
• The damage protection is a guarantee, not a contract of insurance, which means claim handling follows Airbnb’s process and decision standards, not state insurance regulations.

Vrbo runs a parallel set of programs with similar structure. The point is not that AirCover or its Vrbo equivalent is bad: at $0 incremental cost it is real value. The point is that it is not, and was never designed to be, a substitute for an underlying STR-aware policy on the structure and contents.

Dedicated STR carriers: what they actually add

Three categories of dedicated STR insurance carriers operate in the US market in 2026, and they solve different problems.

Building and business policies (Proper Insurance, CBIZ Vacation Rental, Steadily on a landlord chassis). These cover the structure, the contents, business income (loss of rents), liability, and typically equipment breakdown and ordinance/law. They replace the standard HO policy on a property used for STR. Per Steadily’s site (analysed June 2026), baseline landlord liability runs “$300K-$2M of liability into every landlord policy in all 50 states”, with short-term rental coverage available through dedicated quote flows.

Per-booking or supplemental policies (Safely and similar, analysed June 2026). Safely’s product, underwritten by On Demand Insurance Agency LLC, offers “up to $1,000,000 in short-term rental insurance for all booking sites” covering pet damage, intentional guest-caused damage, theft of property contents, bodily injury liability, and accidental damage from guest negligence. The pitch is fast claim handling (the page states “rapid processing with most payments as fast as three business days”). What is structurally important: this is layered protection alongside an underlying policy, not a replacement for one.

Commercial umbrella and excess liability carriers. Above your primary liability stack, an umbrella adds $1M to $5M of additional limit at a relatively low premium for portfolios with real asset exposure. This is the layer that pays when a serious injury claim exceeds the primary limit, which happens more often than operators expect once a portfolio is past 10 doors.

The carrier decision matters less than the policy form. Two operators on the same carrier name can have different coverage if one has a landlord form and the other has an STR endorsement. Ask for the specimen policy. Read the exclusions. The first time an underwriter pushes back is the moment to keep asking.

The gaps operators discover after a claim

A short list of gaps that recur in operator forums and that carriers do not advertise on landing pages:

Mold and slow-leak water damage. Most policies exclude slow leaks and the mold that follows. A guest reports a soft spot on a bathroom floor and the investigation finds a pinhole leak that has been there for months. The water damage to the joist is covered if it traces to a covered peril; the mold often is not. Endorsements exist for limited mold coverage. Read the cap, which is commonly $5K to $25K.

Ordinance or law coverage. When repairs trigger code upgrades (egress windows, electrical, sprinklers), the upgrade cost is not always included in the base building coverage. Ordinance and law endorsements close this gap. On a property built before current codes, this can be the difference between a covered rebuild and a covered partial.

Business income with extended period of restoration. If the structure is unrentable for six months after a fire, the loss of revenue is what business income covers. Default periods are often 12 months. Properties in slow-permit jurisdictions can take longer to repair than the default period allows. The extended period of restoration endorsement extends this, and it is worth asking the limit.

Loss assessment for HOA properties. Condominiums and properties in HOAs can be assessed for common-area damage or liability claims. Standard HO-6 loss assessment limits are commonly $1K to $2K, which is far below typical real-world assessments. STR-specific forms sometimes carry higher loss-assessment limits; sometimes they do not.

Worker-related claims. A cleaner injured on site, a contractor hurt during a turnover repair: workers’ compensation requirements vary by state and worker classification. Liability policies typically exclude employee injuries, treating that risk as a workers’ comp problem. The operator running 1099 cleaners across multiple properties should confirm in writing how their state treats the classification and whether a contingent workers’ comp policy is needed.

These are the categories where the after-claim conversation goes badly when they were not addressed at binding. None are exotic. All are documented in policy specimen forms. None are visible on a marketing page.

A practical frame by portfolio size

The right insurance stack for a 3-property operator is not the right stack for a 25-property operator, and treating both with the same policy form is the most expensive mistake at either end.

1 to 4 properties: STR-endorsed HO or a landlord policy with explicit STR language per property; $1M liability minimum per occurrence; AirCover and Vrbo programs treated as supplemental, not primary. The cost discipline at this stage is reading exclusions before binding, not finding the cheapest premium.

5 to 15 properties: Move to a dedicated STR insurer for any property where the homeowner-style endorsement was a transitional fix. Liability at $1M to $2M per occurrence. Add a $1M to $2M umbrella above the underlying policies. At this scale the operational systems are changing rapidly and the insurance stack should match. Review the loss-of-rents endorsement length against your local permit reality.

15 to 30+ properties: Consider portfolio-level coverage from a commercial carrier rather than per-property policies. A single schedule of locations with one liability limit, one business-income endorsement, and one umbrella is operationally simpler and often cheaper above 20 properties. A broker who actually writes STR portfolios at this scale is worth the conversation, even if the result is to stay on per-property policies.

The decision frame on what platform programs replace is the same at every portfolio size: they do not replace the underlying policy. They sit on top of it.

Tooling that helps without replacing a broker

Operators commonly ask whether the PMS or the channel manager handles insurance integration. The honest answer is no, and the integrations that exist (some PMS provide carrier referrals) are referral relationships, not coverage. The same applies to platform programs: Airbnb’s coverage attaches to Airbnb bookings, Vrbo’s attaches to Vrbo bookings, and a direct booking falls outside both.

A practical operator system that does help: a per-property document folder containing the declarations page, the specimen policy form, the renewal calendar, and the list of named perils. When a claim is reported, the response time is the time to open that folder, not the time to ask the broker which policy is on which property. At 10 properties, a spreadsheet works. At 25, the same kind of operational discipline that a real PMS enforces on bookings belongs on the insurance stack.

What to do this week

Three actions worth taking before the next renewal cycle, ordered by the cost of skipping them.

1. Confirm in writing that your current carrier knows the property is used for short-term rentals. Ask whether the existing policy form covers paid-stay activity. Save the response. If the carrier excludes the activity, you have a fact, not a hope.
2. Read the exclusion list of your platform program. Section 6 of the Airbnb Host Damage Protection Terms is two pages. The list of what is not covered is the list of claims your underlying policy needs to pay. If you do not have an underlying policy, that gap is where the loss falls.
3. Get a specimen policy from one dedicated STR carrier and compare it line by line to what you have. The exclusions differ. The named perils differ. The ordinance/law and mold endorsements differ. The cheap comparison is between premiums, and it is the wrong comparison.

The cost of doing this is a few hours of operator time. The cost of not doing it is the difference between a covered claim and a denied one, plus the carrier conversation that follows.
