Lessor’s risk insurance covers a commercial building you own and lease to somebody else. It answers for three things your tenant’s policy does not touch: the building itself, the rental income it produces, and your liability as owner of premises other people use.
The name is the confusing part
A lessor is the party who leases property out; a lessee is the party who leases it in. So lessor’s risk is simply the risk carried by the person on the ownership side of the lease, and the coverage written to answer it.
You will also see it as Lessor’s Risk Only, usually abbreviated LRO. That is not a different product — it is the underwriting classification for a building occupied entirely by tenants rather than by its owner. The distinction matters because it tells the carrier that the operations inside the building are not yours, which changes both what is covered and how it is rated.
What it covers, in three parts
The building. The structure, what you own inside it, and the systems that serve it. The decisive detail is the valuation basis — whether a loss settles at replacement cost or on a depreciated basis — which is what commercial property coverage turns on and which decides what a total loss actually funds.
The income. Rent stops when a covered loss makes the space unusable, and business income and loss of rents is what replaces it while the building is repaired. This is the piece most often left out or bought too thin by owners who think of insurance as being about the structure. The mechanics of how it pays are worked through in how loss of rents actually pays.
The liability. Somebody is hurt on premises you own but do not run. General liability answers that, with umbrella limits above it where the severity warrants, and tenant discrimination coverage where the exposure runs to how tenants are selected and treated rather than to anything physical.
A placement missing any one of the three is not a lessor’s risk policy. It is a piece of one.
The gap it exists to fill
Owners routinely assume that a tenant carrying good insurance covers the building. It does not, and the reason is worth understanding precisely rather than accepting as a rule of thumb.
A tenant’s commercial policy insures the tenant’s interests: their stock, their equipment, the improvements they paid for, their business income, and their liability to people they deal with. Your building is not their property and is not on their schedule. Your rent is not their income. And when a claim names you as owner — because the injury happened in a common area, or because the plaintiff sues everyone with an interest in the premises — their liability policy is defending them, not you.
There is one mechanism that genuinely reaches across, and it is narrow. An additional insured endorsement puts you onto the tenant’s liability policy for claims arising out of that tenant’s use of the leased premises; the standard industry endorsement for exactly this relationship is ISO form CG 20 11, Additional Insured — Managers or Lessors of Premises. It is worth asking for by name, because a certificate that merely says “additional insured” without the endorsement behind it proves very little. But note what it is: a share of the tenant’s liability limits for the tenant’s premises operations. It does not insure your building, your rents, or a claim that has nothing to do with that tenant. The detail is worked through in what a commercial landlord actually needs on the tenant’s policy.
Real-World Scenario: An owner leases a single-story commercial building to a well-run business that carries proper limits, names the owner as additional insured, and renews on time every year. A fire starts in the tenant’s equipment. The tenant’s policy pays for the tenant’s equipment and inventory, and defends the tenant. The building is the owner’s, and the owner carried nothing on it because the certificate on file looked comprehensive. The rent stops the same day. Nothing was mis-sold and nobody lied — the certificate was exactly what it claimed to be, and it was never a policy on the building.
Who needs it, and who does not
You need lessor’s risk if you own commercial property occupied by tenants — a storefront, a strip, an office building, a building with shops below and occupied space above.
You do not need it if you own and occupy the building your own business runs from. That is a business owners policy or a commercial package, covering the property and the operations together, because the operations are yours.
Owners who occupy part of a building and lease the rest sit between the two, and the placement has to describe that split accurately. Getting it wrong in either direction creates a gap that only shows up at a claim.
What it does not cover
Flood and earthquake are placed separately. Whether your building needs flood coverage is a map question rather than a judgment call, and the National Flood Insurance Program is where that gets answered before you buy rather than after.
Your tenants’ property and their business income are theirs. Wear, deferred maintenance and gradual deterioration are excluded — a policy answers for losses, not for the passage of time.
And the one that surprises owners most: rent that stops because a tenant defaults, breaks the lease or simply leaves is not covered by anything in this placement. Income coverage responds to rent lost because physical damage made the space unusable. A leasing problem is a leasing problem.
The lease is half of the policy
The document that decides most lessor’s risk claims is not the policy. It is the lease, and owners who treat the two as separate paperwork end up with coverage that does not match the obligations they signed.
Four clauses do the work. The insurance requirements clause says what the tenant must carry and at what limits — and it is worth checking that the number written years ago still buys anything. The indemnity clause says who bears a loss between the two of you, which is a contractual promise your tenant’s insurer may or may not be obliged to fund. The waiver of subrogation stops each side’s carrier from paying its own insured and then suing the other party to get it back; without it, your insurer can recover from your tenant, which is a fine outcome for your insurer and a poor one for a tenancy you wanted to keep. And the improvements and betterments clause decides who owns the build-out — because whoever owns it has to insure it, and the commonest gap in this whole product is a fit-out that the lease gave to the owner and that nobody put on either policy.
None of those clauses is exotic and all four are frequently inconsistent with the policy sitting beside them. Reading them together, once, is the highest-value hour available to a commercial landlord. The interaction is worked through in NNN leases: who insures what and waiver of subrogation in a commercial lease.
How the building is actually rated
Occupancy leads. What the tenants do inside — cooking, solvents, open flame, late hours, public foot traffic — moves a schedule further than most physical features. After that: construction class, roof age, protection and location, and then the loss record.
The three type lenses this brand writes to are worth knowing because they price differently. Mixed-use turns on the residential component and the fire separation protecting it. Retail turns on premises liability and what the lease actually transferred. Office turns on building systems and how the building behaves when space empties. What state the building sits in matters too, since vacancy provisions and total-loss settlement rules are state law — compare Pennsylvania with South Dakota and the difference is not cosmetic.
Where to go from here
If you own one building and are buying this coverage for the first time, the terms that will actually decide your claims are the vacancy condition, the valuation basis, and the income period. Each has its own explainer: the vacancy clause and when it starts running, coinsurance on a commercial building, and ordinance or law in plain terms.
General background on commercial lines is published by the Insurance Information Institute, state regulators are indexed by the National Association of Insurance Commissioners, and the Small Business Administration publishes a plain overview of business insurance generally.
