Older Apartment & Mixed-Use Building Insurance

Short answer: Older apartment and mixed-use buildings are hard to insure because of specific, checkable facts: roof age, older wiring and plumbing, vacancy, repeated water claims and ground-floor tenants that cook or serve alcohol. A decline usually reflects one insurer's appetite for those facts, not a finding that the building cannot be insured. What improves the chance of a quote is evidence: dated update records, loss runs (claim histories) that show the repair behind each claim, and complete tenant insurance documents.

For the basics of habitational (residential rental) coverage, see our landlord and property management insurance guide.

Why are older apartment and mixed-use buildings hard to insure?

One fire, burst pipe or storm in a rental building can damage many households at once. Many standard programs set eligibility rules by building age, construction and system updates, so one fact, such as an original electrical panel or a bar downstairs, can put a building outside a program.

In The Council of Insurance Agents & Brokers' national broker survey for Q2 2026, commercial property premiums across all classes fell 6.3% on average while umbrella premiums rose 5.3%, according to an August 19, 2026 report in the Council's magazine, Leader's Edge. National averages say little about any single building. In our experience, when pricing softens and a building is still declined, the reason is usually the building, its tenants or the submission.

All five common problems apply:

Availability: fewer standard programs accept original wiring, older roofs, long vacancies or cooking and bar tenants.
Affordability: higher or percentage-based deductibles shift more of each loss to the owner.
Exclusions and restrictions: reduced roof payments for depreciation, cosmetic hail exclusions, vacancy conditions and assault and battery limits often appear.
Insufficient limits: rebuilding old masonry to current code can cost much more than market value, so limits based on market value often fall short.
Submission quality: an application that lists only the year built reads as original systems, because underwriters generally credit only documented updates.

What do underwriters check on an older building?

Our real estate and property management industry page lists the four systems underwriters ask about most: roof, electrical, plumbing and HVAC (heating and cooling).

Roof

Expect questions about the year of the last full replacement (not the last repair), the covering type, layers and condition. Older roofs in hail-prone areas often draw cosmetic hail exclusions or actual cash value terms, which pay replacement cost minus depreciation.

Electrical

Underwriters typically ask whether knob-and-tube wiring is still energized, whether fuses remain, which panel brands serve the units and whether the building has aluminum branch wiring. The U.S. Consumer Product Safety Commission says in Publication 516 that wiring installed between 1965 and the mid-1970s may contain aluminum. An electrician's letter naming the wiring, panels, service size and any repairs answers these questions at once.

Plumbing and heating

Galvanized supply lines, polybutylene piping, cast-iron drains, water heater ages, boiler certificates and freeze protection for empty units all draw questions. Repeated water claims from old plumbing are often a reason for a decline. Our water damage guide for condo and apartment buildings explains water deductibles and sewer backup coverage.

Fire protection

Sprinklers and monitored alarms help, and a protective safeguards endorsement (an attached policy change) can make them a condition of coverage. Under ISO's version of that endorsement (CP 04 11), as described by Adjusters International, the insurer will not pay for fire damage if, before the fire, you knew a listed safeguard was suspended or impaired and did not tell the insurer, or failed to keep a listed safeguard under your control in complete working order. Wording varies by insurer, so read your policy's schedule and conditions.

Vacancy

According to January 2026 commentary from IRMI, ISO's standard building and personal property form (CP 00 10) treats an owner's building as vacant unless at least 31 percent of its total square footage is rented and used for customary operations or used by the owner. If the building has been vacant for more than 60 consecutive days before a loss, that form does not pay for vandalism, sprinkler leakage (unless the system was protected against freezing), building glass breakage, water damage, theft or attempted theft, and it reduces payment for other covered losses by 15 percent, as the same 2026 IRMI commentary explains. The form says a building under construction or renovation is not vacant, but it does not define renovation, and courts reach different conclusions. Ask about a vacancy permit endorsement before work starts. Many insurers use their own forms, so the policy actually issued controls.

Loss history

Underwriters commonly want five years of currently valued loss runs, meaning recent claim reports from each prior insurer. Frequency often worries them more than one large loss, because repeated claims suggest an unfixed condition. A note for each claim naming the cause and the repair, with the invoice, often changes the answer.

What changes when the ground floor is a restaurant or bar?

A restaurant tenant adds grease-fire exposure below sleeping residents, and a bar adds late hours, crowds and assault claims. Many business owners policy (BOP) programs limit or exclude these tenants, so mixed-use buildings often need a commercial package policy built from separate property and liability parts. Underwriters typically ask:

Does the kitchen have a hood, duct and automatic extinguishing system, and who cleans and inspects it? The standard underwriters usually reference is NFPA 96, which covers ventilation control and fire protection of commercial cooking operations.
Does the lease require the tenant's general liability, and liquor liability for a bar, to name you as an additional insured (a party the tenant's policy also protects), with a current certificate every year?
Are the commercial space and the apartments separated, with their own utilities and exits?

In Missouri, RSMo 537.053 allows a claim against a licensee that sells alcohol by the drink only on clear and convincing evidence that it served someone under 21 it knew or should have known was underage, or knowingly served a visibly intoxicated person. That exposure sits mainly with the bar, but underwriters often treat a bar tenant as an added assault exposure for the whole building. Check the assault and battery terms of your own general liability coverage.

Which policy terms matter most on an older building?

Check these terms on the declarations page (the policy's summary of coverages, limits and deductibles) and endorsements:

Valuation and limits. A commercial property policy may pay replacement cost or actual cash value. Set limits from a current replacement cost estimate, because a coinsurance clause can cut partial-loss payments when limits run low, as our multifamily limits guide explains.
Ordinance or law. Standard forms typically do not pay the extra cost of rebuilding to current code or demolishing undamaged sections, and older buildings often carry too little of this coverage.
Wind and hail deductibles. Percentage deductibles (a share of insured value) often apply to older roofs in hail-prone states. Missouri recorded 253 major hail events (hail one inch or larger) in 2025 and Kansas recorded 375, fifth and second among states, according to the Insurance Information Institute's tally of NOAA Storm Prediction Center data.
Liability and umbrella. Habitational general liability often carries assault and battery, lead and habitability exclusions or sublimits. Federal lead-based paint disclosure rules apply to housing built before 1978, except 0-bedroom dwellings and housing for the elderly or persons with disabilities (unless a child under 6 lives or is expected to live there), as defined in 24 CFR 35.86. Excess insurers may require specific underlying terms, as explained on our umbrella and excess liability page.
Surplus lines warranties. Missouri allows coverage from eligible surplus lines (nonadmitted) insurers when the full amount or kind of coverage is not available from admitted insurers (RSMo 384.017). Their policies can carry warranties that the building has no aluminum wiring or certain electrical panels, and the presence of that wiring or those panels can void fire coverage, according to 2023 commentary from the Independent Insurance Agents & Brokers of America's Big "I" Virtual University.

Missouri and Kansas: what actually differs

Underwriters generally ask the same questions in both states, and we found no verified difference in how insurers approach this class. These rules do differ:

Topic	Missouri	Kansas
Nonrenewal notice	Property: 30 days' written notice, or 10 for nonpayment (20 CSR 500-1.100). Commercial liability: at least 60 days (RSMo 379.883)	At least 60 days on business property and casualty policies (K.S.A. 40-2,121)
Renewal premium increase of 25% or more	At least 60 days' notice, not counting increases from changed operations or exposures (RSMo 379.321)	No equivalent verified for this article
Workers' compensation for building staff	Generally required with five or more employees, or one or more for construction industry employers (RSMo 287.030)	Generally required unless gross annual payroll was $20,000 or less last year and is expected to stay at or below that (K.S.A. 44-505)

Missouri property policy notices of cancellation, nonrenewal or reduction issued on or after July 1, 2024 must state the reason and give contact details for the Missouri Property Insurance Placement Facility, under 20 CSR 500-1.100. Known as the Missouri FAIR Plan, it is a last-resort market, and its commercial coverage is a named-peril policy with a per-location limit, so it may not fit a larger building. Ask your agent whether these notice rules apply to a surplus lines policy.

Underwriters also ask for city inspection records, and open code violations can lead some insurers to decline. In St. Louis, a rental unit needs a Certificate of Inspection before occupancy under Ordinance 71835, with reinspection every three years or on a change in occupancy, according to the city's Building Division. Kansas City, Missouri's complaint-based Healthy Homes program requires an annual permit for each rental unit, per a 2019 notice from the Kansas City Regional Association of Realtors; confirm current rules with the city. In Kansas City, Kansas, residential landlords have needed a rental license since 1996, and licenses expire April 30 each year, according to the Unified Government. A qualified attorney should review how any statute or ordinance applies to your building and staff.

Illustrative scenario: a 1920s building with a bar downstairs

Illustrative example: hypothetical and simplified. It does not describe a real organization, claim or policy.

An owner held a three-story 1920s brick building in Kansas City, Missouri, with a restaurant and bar on the ground floor and 12 apartments above. The insurer sent a nonrenewal notice citing roof age and loss history, and a resubmission of the old application drew only declines. The file showed a patched flat roof about 20 years old, two water claims from failed galvanized lines, three units empty for renovation, "unknown" for the electrical system and the tenant's expired certificate of insurance.

The owner assembled a roofer's report and replacement contract, an electrician's letter confirming no energized knob-and-tube wiring, invoices for replacing the galvanized supply lines, renovation permits, the tenant's current certificate with liquor liability, hood service records and a replacement cost estimate.

One insurer offered terms with conditions: actual cash value on the roof until replacement, a percentage wind and hail deductible, a protective safeguards endorsement for the kitchen system and alarm, a water damage deductible and an assault and battery sublimit. The owner added ordinance or law coverage and extended loss of rents (rental income lost during repairs).

What would have changed the outcome: sending those documents the first time, so the file answered the underwriters' questions instead of raising them.

Documents that strengthen a submission

A statement of values (each building's insured value) based on a current replacement cost estimate.
Roof replacement year, covering type, invoice, condition report and photos.
An electrician's letter on wiring, panels, service size and repairs.
Plumbing materials, repiping invoices, water heater ages and boiler certificates.
Sprinkler, alarm and extinguisher inspection reports.
Five years of currently valued loss runs, with a cause-and-repair note for each claim.
A rent roll showing occupancy by unit and square footage, plus renovation schedules and permits.
Commercial leases, tenant certificates, liquor liability evidence and hood cleaning records.
City inspection certificates, rental permits or licenses, and code violation status.
Lead disclosure practice for pre-1978 buildings, security measures and lender insurance requirements.

If a nonrenewal notice has arrived, start a review by sending it with your declarations page.

How BluePeak can help

BluePeak Digital Insurance helps businesses and nonprofits understand why their coverage options may be limited, prepare stronger underwriting submissions, and explore appropriate insurance markets where available. As part of our commercial insurance services, for an older or mixed-use building we:

Review your declarations pages, forms, endorsements, exclusions and limits.

Frequently Asked Questions

Will replacing the roof get my older building quoted?

A new roof often helps, because roof age is one of the first things a property underwriter checks. It does not answer questions about wiring, plumbing, vacancy or loss history, so pair it with records for the other building systems. Terms still depend on each insurer's underwriting.

Is a vacant unit covered if it is vandalized during a renovation?

It depends on the policy's vacancy condition. In ISO's standard commercial property form, the vacancy test applies to the whole building, so a few empty units in an otherwise occupied building usually do not trigger it. Some insurers use stricter forms, so read your policy and tell your agent about renovation plans before work starts.

Does my restaurant tenant's insurance protect me as the building owner?

Only to the extent the lease requires it and the tenant's policies name you as an additional insured. Depending on the endorsement, that status is often limited to claims tied to the tenant's operations or space. The tenant's policies generally do not insure your building or your own liability as the owner, so you still need coverage written for the building.

Does an older building have to go to the surplus lines market?

Not automatically. Some admitted (state-licensed) insurers write older buildings whose systems have been updated and documented. Buildings with original systems, significant vacancy or a bar tenant more often go to surplus lines (nonadmitted) insurers, whose forms and warranties need a careful read.

Can BluePeak help if my building is in Kansas?

Yes. BluePeak is licensed in Kansas as well as Missouri, so we can review your program and prepare the submission. Which insurers will consider it depends on their appetite and the markets available to us, and we will tell you plainly what we find.
