How Do You Insure an Office or Medical Office Building in Texas?

What Insurance Does a Texas Office or Medical Office Building Need?

Most owners need six core pieces: building property, loss of rents, equipment breakdown, general liability, an umbrella and ordinance or law. Flood and a plan for vacant space fill the most common gaps. The table shows what each one is for.

Many owners carry these in one package policy, with a separate umbrella and flood policy. For a short overview of this property type, see our office and medical buildings page.

How Much Should You Insure the Building For?

Insure it for what it would cost to rebuild today, not what you paid. Your purchase price includes land, leases and location. Rebuilding cost is labor and materials.

Medical office buildings often cost more to rebuild than plain office space of the same size. Exam rooms need more plumbing, more electrical circuits and heavier HVAC. Imaging suites can need special walls and floors. Make sure your statement of values reflects what is really built, and update it at each renewal.

Most property policies include a coinsurance clause. It asks you to carry a limit of at least a set percentage of the building's value, often 80% or 90%. If you carry less, the insurer pays only part of each claim.

Some policies offer an agreed value option that suspends coinsurance until the date shown on the policy, usually one year, when you support your values. Our coinsurance guide has more examples.

Who Insures Tenant Improvements?

Whoever the lease says. Tenant improvements and betterments are the walls, ceilings, flooring, lighting and built-ins added for a tenant. In office and medical buildings, they can be worth more than the shell of the suite.

Many leases make the landlord insure the base building and common areas, and make the tenant insure its own improvements and contents. Trouble starts when the lease is silent, or when you paid a large build-out allowance. Then both policies may try to cover the same work, or neither one does.

Ask your agent to read the insurance and casualty clauses of your main leases before renewal. Have a real estate attorney draft or change the lease language itself.

Do You Need Equipment Breakdown for Elevators, Chillers and Switchgear?

Usually, yes. A standard property policy covers equipment damaged by outside causes such as fire. It usually doesn't pay when a machine breaks down on its own, from a motor burning out or an electrical arc.

Equipment breakdown coverage is built for that gap. In an office or medical building, it can apply to:

• Vertical transportation: elevator motors, controllers and drives.
• Cooling and heating: chillers, cooling towers, boilers and large rooftop HVAC units.
• Electrical: switchgear, transformers, panels and emergency generators.
• Life safety: fire pumps and building automation controls.

Depending on the form, it can also pay lost rent while equipment is down, extra costs to rush repairs, and spoilage. It usually doesn't cover slow wear and tear, so maintenance records matter.

What Does Texas Law Say About Elevator Inspections?

Texas law generally requires the owner of an elevator or escalator to have it inspected every year by a registered elevator inspector. The owner must file the inspection report with the state within 30 days after the inspection and display the certificate of compliance where the public can see it (Health & Safety Code §754.019). Underwriters often ask for these reports, so keep them handy.

How Do Water, Freeze and Sprinkler Leaks Hit a Multi-Story Building?

Hard. Water travels down, so one burst pipe on the third floor can soak ceilings, walls and equipment on every floor below it. Medical suites full of equipment and finished space can make that bill large fast.

Freeze is a real Texas risk. In TDI's data on the February 2021 winter storm, commercial property made up about 10% of claims but about 53% of incurred losses. The average incurred loss per commercial claim was about $149,100, as of March 2022 (TDI).

• Sudden leaks. Most special-form policies cover sudden water damage from a burst pipe. Slow, repeated leaks are commonly excluded.
• Frozen pipes. Freeze damage is often covered only if you kept heat on or drained the system.
• Sprinklers. Sprinkler leakage is usually covered when sudden, subject to the vacancy rule.
• Mold. Most policies limit mold sharply under a mold exclusion, so fast drying matters.
• Power outages. Damage from an off-site power failure may need utility services coverage, depending on the wording.

Simple steps help. Label the main water shutoffs, train your engineer or manager to use them, and keep the sprinkler system inspected. Water-flow alarms tied to a central station alarm can cut the time water runs after hours.

What Changes When Your Tenants Are Medical Practices?

Medical tenants bring more equipment, more build-out, more visitors and stricter lease terms. Tell your insurer the tenant mix, because medical uses can change how underwriters rate the building.

• Medical gases. Some tenants store oxygen or other compressed gases, and some buildings have piped gas systems. Underwriters often ask how they are stored and maintained.
• Imaging equipment. MRI, CT and X-ray machines usually belong to the tenant or a leasing company. They are usually insured on the tenant's own property and equipment breakdown coverage. The shielded rooms built for them are costly improvements, so the lease should say who insures those.
• Medical waste. Practices produce sharps and other biohazard waste. The lease should make each tenant responsible for handling and removing its own waste properly. Many liability policies limit pollution claims under a pollution exclusion, so ask how yours treats this.
• Refrigerated supplies. Vaccines and medicines can spoil in a power outage. That loss usually belongs on the tenant's policy.
• Backup power. Surgery centers and dialysis clinics may rely on generators. Include owner-owned generators in your equipment breakdown schedule.

If you only lease space to others and don't occupy it or run a business there, a lessor's risk only liability policy may fit, with one tenant or many. If you or a related company occupy space, or run services such as the garage, tell your agent so the right liability policy is used.

How Much Loss of Rents Coverage Do You Need?

Enough to replace all rent and expense recoveries for as long as a realistic rebuild takes. For office and medical space, that includes design, permits, construction and rebuilding tenant suites.

Office leases often let rent stop when a suite can't be used. Some also let a tenant end the lease after a long closure. Count base rent plus any operating expenses tenants reimburse, and plan for the costs you keep paying, such as taxes and loan payments.

The period of restoration usually ends when the space should be repaired, not when it is leased again. An extended period of indemnity can keep paying for a set time after repairs while you refill the space. Our loss of rents guide goes deeper.

Who Is Responsible for Injuries in the Lobby, Parking Lot or Garage?

Often you, the owner. Lobbies, elevators, stairs, sidewalks, parking lots and garages are usually under your control. Your general liability policy may have to respond to a slip-and-fall claim there, even when the person was a tenant's patient.

Premises liability claims often turn on what you knew and what you did about it. Medical buildings see many older visitors, people using walkers or wheelchairs, and patients leaving after procedures, so small hazards matter.

• Keep lighting working in garages and stairwells, and log repairs to curbs, ramps and wheel stops.
• Keep dated records of cleaning, inspections and spill response, especially at entrances on rainy days.
• Think about security in garages and after-hours areas. A negligent security claim can follow a crime on your property.
• If a parking company runs the garage, require it to carry its own liability insurance and name you as an additional insured.
• Report incidents to your agent promptly, even before anyone files a claim.

Lenders and larger tenants often require an umbrella, and a busy multi-tenant building usually justifies one. This is general information, not legal advice. If you get a demand letter or lawsuit, send it to your insurer right away and talk to an attorney.

What Should Your Leases and Contracts Require?

Each tenant should carry its own liability and property insurance, name you as an additional insured, and prove it every year. Typical lease insurance requirements include:

• General liability at a set limit, naming the landlord, and often the lender and property manager, as additional insureds.
• Wording that makes the tenant's policy primary and noncontributory, so it pays before yours.
• A waiver of subrogation on both sides, so insurers don't sue each other's insured after a covered loss.
• Property coverage for the tenant's improvements, equipment and contents, as the lease assigns them.
• Professional liability for medical tenants, as a separate requirement from general liability.
• Notice to you if the tenant's policy cancels.

Hold elevator, HVAC, janitorial and roofing contractors to the same standard. Track every policy date in one list and request new proof 30 days before each one expires. Our guide to additional insureds and certificates explains more, and a real estate attorney should draft the lease language.

Do You Need Hail, Flood and Ordinance or Law Coverage?

Often yes. Hail and flood are the big Texas weather risks for office buildings, and older buildings face code costs after a large loss.

Hail and Rooftop Equipment

Texas had more major hail events than any other state in 2025, according to the Insurance Information Institute. Office roofs often carry chillers, cooling towers and HVAC units whose coils dent easily. A wind and hail deductible is often a percentage of the building's insured value. On a building insured for $12,000,000, a 2% deductible is $240,000 (hypothetical). Check how each quote values older roofs under its roof age terms.

Flood

Standard property forms exclude flood. The NFIP covers up to $500,000 for a non-residential building and $500,000 for contents. Each policy covers one building, pays at actual cash value and doesn't pay lost income (FEMA). New policies usually have a 30-day waiting period (FloodSmart). Electrical rooms, generators and imaging suites on the ground floor are especially exposed. Many owners add excess flood or private flood coverage. See our Texas flood guide.

Ordinance or Law

After a large loss, the city may require current fire, life-safety or energy code work, or tear-down of the undamaged part. The ordinance or law endorsement (ISO form CP 04 05) has three parts, each shown with its own limit: the loss to the undamaged portion, demolition cost, and the increased cost of construction. Older office buildings need it most. Our ordinance or law guide explains each part.

Near the coast, private policies may exclude wind and hail. Our TWIA guide explains when the state's windstorm pool comes in.

What Happens When a Large Tenant Leaves?

If too much space empties out, the building can count as vacant and coverage shrinks. Under the standard commercial property form, an owner's building is vacant unless at least 31% of its square footage is rented and used for the tenants' normal operations, or used by the owner. A signed lease alone doesn't count if the space sits empty (IRMI).

After more than 60 consecutive days of vacancy, there's no coverage for vandalism, sprinkler leakage (unless protected against freezing), building glass breakage, water damage, or theft. Other covered losses are cut by 15%.

Tell your agent as soon as you know a big tenant is leaving. Our vacant building guide covers your options.

Do Owners Need Cyber or Crime Coverage?

Some do. Building systems, tenant payment portals and email all create risk. A fake email asking you to change a vendor's bank details is a common scheme. That usually needs social engineering fraud coverage under a crime or cyber policy. If you employ building staff, ask about employment practices liability too.

What Do Underwriters Ask, and How Do You Prepare?

Underwriters want to see the building, its systems, the tenant mix and your claim history clearly. A complete submission usually gets more carriers to quote. Commercial property premiums fell 6.3% on average in the second quarter of 2026, according to the Council of Insurance Agents & Brokers (Insurance Journal). That can make it a good time to review your program, though your own price depends on your building.

1. A rent roll with each tenant's name, use (office, medical, imaging, surgery and so on) and square footage.
2. Stories, square footage, construction type and year built, plus updates to roof, wiring, plumbing and HVAC.
3. Elevator count and recent inspection reports, and the age of chillers, boilers and switchgear.
4. Garage details: levels, who operates it, lighting and security.
5. Sprinkler, fire alarm and security details, and any medical gas storage.
6. A current statement of values and flood zone details, with any elevation certificate.
7. Your lease insurance clauses. We'll review them against what tenants can actually buy.
8. Five years of loss runs and your lender's insurance requirements.

When you have these, request a quote or read how we work. If something is missing, send what you have and we can help fill the gaps.
