Insurance for Vacant Buildings
Standard property policies cut back once a building sits empty, while liability for trespassers keeps running. We look for coverage for California owners between tenants, mid-renovation or waiting on a sale, and an insurer decides based on the building’s condition, security and how long it will sit empty.
When a building sits empty
Buildings go empty for ordinary reasons. An anchor tenant leaves a strip center, an industrial building waits for its next lease, an investor buys a property to gut and reposition, or a family trust lists an inherited office building for sale. Each is a normal step in owning real estate, and each one changes how the property insurance responds.
The risk shifts because nobody is around to notice. A slow roof leak runs for weeks, copper wiring is stripped overnight, and people looking for shelter find a way in. Insurers price that difference, and most commercial property forms cut coverage back on their own once the building has been empty long enough. If you also own occupied buildings, our page on insurance for landlords and commercial property owners covers the rest of the portfolio.
The 60-day vacancy condition
The standard ISO commercial property form, CP 00 10, carries a vacancy condition. IRMI explains that once a building has been vacant for more than 60 consecutive days before a loss, the form pays nothing for vandalism, sprinkler leakage unless the system was protected against freezing, glass breakage, water damage, theft or attempted theft. Payment for any other covered cause of loss, fire included, is reduced by 15 percent.
Those excluded perils are the losses an empty building actually suffers. A burst pipe, a break-in or a smashed storefront is what happens in month three of a vacancy, and the policy written while the building was full stops answering for it. Owners who discover this after a loss face the repair bill alone, so the date a building empties belongs on your calendar and on ours.
Vacant, unoccupied or under renovation
The two words mean different things. IRMI’s commentary describes an unoccupied building as one with property inside but no people, and a vacant building as one with neither. For an owner, the form measures the whole structure: unless at least 31 percent of the total square footage is rented and used by tenants for their customary operations, the building counts as vacant. On a tenant’s policy, the building is the tenant’s own unit, which is vacant once it lacks enough business property to carry on customary operations.
The 31 percent test catches owners off guard. A three-tenant retail building that loses its grocery anchor can drop below the line with two small shops still trading. Buildings under construction or renovation are not considered vacant under the form, which helps an owner mid-remodel, so keep your underwriter informed if the work pauses and keep the project description on the policy current.
Vacancy permits and vacant building policies
When a vacancy is planned and short, the fix is often a vacancy permit endorsement on the existing policy. ISO’s version, CP 04 50, suspends the vacancy condition for the permit period shown on the endorsement, and IRMI notes that the insurer can still exclude vandalism and sprinkler leakage during that period. Ask for the permit before day 60, and read which perils it restores.
Longer vacancies, buildings in poor repair and properties bought to redevelop usually move to a vacant building policy written for empty property in the specialty market. The terms attached to those policies are where they differ most: security conditions, inspection visits and the length of the term. Once tenants return, the building goes back on a standard commercial property insurance policy, and the vacancy policy comes off.
Liability for an empty building
An empty building still has an owner, and the owner still answers for it. California Civil Code section 1714 holds everyone responsible for injuries caused by a want of ordinary care in managing their property, and that duty keeps running after the tenants leave. A loose parapet that falls on a sidewalk, an unlit stairwell or a sinkhole in the parking lot can bring a claim from a passerby, a contractor or a broker showing the space.
Trespassers raise their own questions. Cornell’s Legal Information Institute summarizes the attractive nuisance doctrine as liability for a dangerous condition on land that tends to draw children onto it, where the owner fails to take reasonable care to remove the danger. An open elevator shaft, an unfenced pool at a closed motel or an excavation pit fits that description. Keep general liability in force on every vacant property, and make sure the policy describes the building as vacant so the exposure you reported matches the one you have.
Security and inspections underwriters ask about
Underwriters of empty buildings ask practical questions. Are doors and ground-floor windows locked or boarded? Is there a monitored alarm, camera coverage or a patrol service? Who visits the property, how often, and is each visit logged? Are utilities on or off, and if the building has fire sprinklers, is the system heated or drained so it cannot freeze? The answers shape whether a carrier writes the building at all and what it charges.
Put the routine in writing. A weekly inspection checklist with dated photos, a log of who holds keys, quick removal of graffiti and dumped debris, and a record of every repair make a strong file for the underwriter and a strong position after a claim. Keep landscaping trimmed and mail collected so the building does not advertise that it is empty.
San Francisco and Oakland vacancy rules
Some California cities add their own obligations. San Francisco requires owners to register a vacant building with the Department of Building Inspection within 30 days of vacancy and to re-register every year, and registration is not required while a lease or sale is pending. The application asks for the owner’s fire and liability insurance provider and copies of the policies, and an owner without that insurance files an Affidavit of Uninsured Vacant Property Risks instead. The city then schedules an inspection.
Oakland takes a tax approach. Measure W, approved by voters on November 6, 2018, created a Vacant Property Tax on property in use less than 50 days in a calendar year that has no exemption, at $6,000 per nonresidential parcel and $3,000 per parcel where ground-floor commercial space sits vacant. Check your own city’s rules before a building goes dark, because a registration notice or tax bill tends to arrive at the same time as the insurance gap.
What vacant building insurance costs
Published figures for empty buildings are thinner than for occupied ones. Insureon reports a median of $108 a month for commercial property bought by its small-business customers, with annual premiums from under $350 to more than $15,000, and those figures describe occupied premises. For vacant property, one specialty broker’s published example puts a vacant 10,000 square foot commercial building valued at $500,000 at $3,000 to $8,000 a year. Read both as published industry data for small owners at standard limits, not a Mithril1 quote; larger and older buildings run well above them.
The price scales with the building’s value. Insureon describes property premiums as the property value divided by $100, times a base rate that usually runs from $0.30 to $0.80 per $100, and the same broker reports vacant rates of 2 to 5 times the occupied rate per dollar of coverage. An $800,000 building at an occupied rate of $0.40 per $100 comes to $3,200 a year; at 2 to 5 times that rate, the vacant figure lands between $6,400 and $16,000.
A premium runs higher for a building in a high-crime area, one with no alarm or with unsecured openings, a long or open-ended vacancy, a worn roof or old wiring, or liability added to the property policy. It runs lower with secured openings, a monitored alarm and cameras, logged inspections, a short vacancy with a lease or sale in view, and a building in good repair.

A few useful answers
Common questions
When does a commercial building count as vacant for insurance?
On the standard ISO form, an owner’s building is vacant unless tenants rent and use at least 31 percent of its total square footage for their customary operations. The coverage cutbacks start after 60 consecutive days in that state.
Is a building under renovation treated as vacant?
Not on the standard form, which excludes buildings under construction or renovation from the vacancy condition. Tell your underwriter if work stops for a long stretch, and keep the project details on the policy up to date.
What does a vacancy permit endorsement restore?
It suspends the vacancy condition for the permit period printed on it. The insurer can still carve out vandalism and sprinkler leakage, so read the endorsement for the exact perils it gives back.
Do I still need liability insurance on an empty building?
Yes. Owners remain responsible for injuries caused by careless management of their property, and brokers, contractors, inspectors and trespassers all come onto an empty site.
Does San Francisco ask about insurance when I register a vacant building?
Yes. The registration application requests the owner’s fire and liability insurance provider and copies of the policies, or an affidavit of uninsured vacant property risks from an owner without them.
