Insurance for a building I rent to a business tenant in Arizona

Short answer

If you own a building in Arizona and lease it to a business tenant, the coverage built for you is lessor's risk only (LRO) insurance. It covers the building itself against fire, storms, and other perils, gives you liability protection for the property you own, and can replace lost rent if a covered loss makes the space unusable. Your tenant's commercial policy protects their business and contents, not your structure, so relying on it leaves your biggest asset exposed. BrokerPro places LRO across Arizona, including older, vacant, and previously declined buildings.

You bought a commercial building, or you’ve owned one for years, and now a business leases the space from you. You collect rent; they run their company. Then the question lands: whose insurance actually protects the building if something goes wrong? Your tenant hands you a certificate and assures you they’re covered, but covered for what, exactly?

The short version: the coverage built for your situation is called lessor’s risk only (LRO) insurance, and it’s probably not what you have if you never asked for it by name.

What insurance do I need for a building I rent to a business tenant?

You need a policy on the building you own, written for an owner who leases to others. That’s lessor’s risk only (LRO) insurance, and it does two jobs. First, it covers the structure itself against fire, storms, vandalism, and similar perils, paying to repair or rebuild. Second, it provides liability coverage for claims tied to your ownership of the property, such as someone hurt in a common area who points to a condition of the building.

LRO is distinct from the policy a business buys for its own operations, and it’s distinct from the homeowner-style “landlord insurance” people associate with residential rentals. If you want the full definition and how the pieces fit together, including how LRO compares to standard commercial property and to residential landlord coverage, start with our explainer on what lessor’s risk only insurance is.

Do I need insurance if my tenant already has a policy?

Yes, and this is the costliest misunderstanding owners make. Your tenant’s commercial policy is built around their business: their liability, their inventory, their equipment, their income. None of it is obligated to repair the building you own.

Even when your lease requires the tenant to name you as an additional insured, that’s liability protection against claims arising from the tenant’s activities. It is not property insurance. If the roof fails, a pipe bursts over a weekend, or a fire starts next door, the tenant’s insurer isn’t rebuilding your structure. The owner who carries no LRO is the owner who pays out of pocket.

Read the lease the other direction, too. You should require the tenant to carry their own general liability and to name you as additional insured, while you carry LRO on the building. The two policies cover different things, and both should exist.

Does LRO cover loss of rent if the space is damaged?

It can, when you add loss of rental income (sometimes called rental value coverage). If a covered loss makes the leased space unusable and rent stops during repairs, this reimburses the income you would have collected for the restoration period, up to your limit and time cap.

A worked example shows why it matters. Say your tenant pays $4,500 a month and a fire takes the building out of service for five months. That’s $22,500 of rent you never collect, while the mortgage, property taxes, and insurance keep coming due. Loss of rental income is designed to fill that gap. It’s typically an add-on rather than automatic, so confirm it’s on your quote and that the time limit is long enough for a real rebuild.

Does lessor’s risk cover a vacant commercial building?

Standard commercial property forms restrict coverage once a building has been vacant for more than 60 consecutive days. After that window, losses from vandalism, theft, water damage, glass breakage, and sprinkler leakage are typically excluded, and other covered losses, including fire, are paid roughly 15% short. This reflects ISO commercial property language as summarized by industry references such as IRMI and Adjusters International; the exact wording can vary by form edition and carrier.

And “vacant” has a technical meaning. For a building leased out, the form generally treats the whole building as vacant unless roughly 31% of its square footage is actually rented and in use. So a building that’s mostly empty between tenants can trip the vacancy rule even if one small suite is occupied.

The fix is to tell your broker the moment a building is heading toward empty. A vacancy permit endorsement can restore coverage during a turnover or renovation. Vacancy is also one of the reasons a building gets hard to place, and why it sometimes lands in a surplus-lines market.

Can I get LRO if I occupy part of the building myself?

Sometimes a straight LRO policy fits, and sometimes a different policy fits better. LRO is built for owners who lease space to others. If you also run your own business out of part of the building, you have a mixed exposure, owner and operator at the same address, and a straight LRO policy may not be the right structure.

In many mixed-occupancy cases a businessowner’s policy (BOP), or an LRO with the right occupancy endorsements, is the cleaner answer. The dividing line is who operates inside the walls. Tell your broker the exact split: how many tenants, how much of the square footage you occupy, and what each business does, so the policy is written to match reality. The wrong classification can leave a gap exactly where you assumed you were covered.

What if I formed an LLC to hold the building?

Put the LLC on the policy. If the building is owned by an LLC, the LLC should be the named insured on the LRO policy, the policy should align with any mortgage, and any other owners or lenders should be listed as their interest requires. The liability side of LRO then protects the entity against suits tied to the property.

An LLC is a legal wrapper around the asset; it doesn’t pay claims. Insurance does, and the two need to point at the same owner. If the LLC has employees, Arizona generally requires workers’ compensation; a single-member LLC with no employees usually doesn’t.

Frequently asked

Whose policy covers the building, mine or my tenant's?

Yours. The structure is your asset, so it belongs on your policy, and lessor's risk only (LRO) is the form written for it: it pays to repair or rebuild the building after a covered loss and carries liability for claims tied to your ownership, such as someone hurt in a common area. Your tenant's commercial policy is built around their business, their inventory, and their operations, and it has no obligation to rebuild what you own. Even when your lease names you as an additional insured on the tenant's liability policy, that is liability protection, not property coverage on the structure. Both policies should exist, each doing its own job.

Do I still need my own coverage if the lease makes the tenant insure the building?

Yes, in almost every case. A lease can require the tenant to carry insurance and even to name you as an additional insured, but that does not put the structure on their policy or make their insurer responsible for rebuilding what you own. Some triple-net leases push building insurance onto the tenant, and where that happens you still want to be the named insured or hold your own lessor's risk only policy so a lapse, a coverage dispute, or a tenant that stops paying does not leave your largest asset uninsured. Have your broker read the lease's insurance clause against the policy that is actually in force, rather than assuming the two line up.

What is the best insurance for a commercial rental property?

For a building you own and rent to a business, the policy designed for the job is lessor's risk only (LRO), which covers the structure plus liability tied to your ownership. "Best" is less about a brand and more about a fit: the right form for the building's age and construction, loss-of-rents added, vacancy handled if the space turns over, and lender-ready evidence of insurance when there is a mortgage. Older buildings, prior claims, or a high-hazard tenant can move the account to a surplus-lines market, which is normal. Because LRO is a niche line, comparing it through an independent broker who places it across multiple carriers usually beats a single direct quote.

How much does lessor's risk insurance cost in Arizona?

It depends on the building's replacement cost, age, construction, location, occupancy, and the limits you choose, so any single number is only a starting point. As a reference, The Hartford reports its lessor's risk customers pay roughly $1,972 a year on average, or about $164 a month, as of 2026. Older buildings, vacancy, prior claims, or a tenant in a high-hazard trade push the price up and can move the account to a surplus-lines market. The only way to know your number is a quote on the specific building.

Do I need landlord insurance if my tenant already has business insurance?

Yes. Your tenant's commercial general liability and contents policy protects their business, their inventory, and claims tied to their operations. It does not insure your building. If a fire, storm, or burst pipe damages the structure, the tenant's insurer has no obligation to rebuild what you own. Being named as an **additional insured** on the tenant's liability policy is useful, since it can defend you against suits arising from the tenant's activities, but it is not property coverage and it does not pay to repair the building. You still need your own lessor's risk only (LRO) policy on the structure.

How do I get a lessor's risk quote, and which carriers write it?

Lessor's risk only (LRO) is a specialty line, so carriers usually ask for a short LRO supplemental application: the building's address, age, construction, square footage, what each tenant does, the lease terms, any vacancy, and prior losses. Both standard and surplus-lines carriers write it, and which one fits depends on the building, an older property or one a standard carrier declined often lands in the surplus-lines market. Rather than chasing individual company names, it is usually faster to submit the building once through an independent broker who shops several LRO markets at once. BrokerPro places LRO across Arizona, including older, vacant, and previously declined buildings.

Does lessor's risk insurance cover a vacant commercial building?

Often not on standard terms once it sits empty for a while. Most ISO commercial property forms cut coverage when a building has been **vacant** for more than 60 consecutive days before a loss: vandalism, theft, water damage, glass breakage, and sprinkler leakage are excluded, and other covered losses (including fire) are paid 15% short. For a building leased to one tenant, the policy generally treats it as vacant unless roughly 31% of the square footage is actually rented and in use. A vacancy permit endorsement can restore some protection. Tell your broker before the space empties out.

Does LRO cover loss of rent if my tenant's space is damaged?

It can, when you add loss of rental income (also called rental value or business income for landlords) to the policy. If a covered loss makes the leased space unusable and your tenant stops paying rent during repairs, this coverage reimburses the rent you would have collected for the restoration period, up to your limit and time cap. That keeps your mortgage and operating costs current while the building is rebuilt. It is usually an add-on rather than automatic, so confirm it is on your quote.
