Condo insurance covers the inside of your unit, but not the building itself

Condo insurance—also called HO-6 coverage—protects your belongings, the walls and fixtures inside your unit, and your liability if someone is injured in your home. It does not cover the building's structure, roof, or common areas. The condo association's master insurance policy covers those. This split matters because you need both policies working together, and gaps between them can leave you uninsured.

Your mortgage lender requires you to carry condo insurance before closing. They want proof that your belongings and the interior of your unit are protected, because if a fire or theft wipes out your investment, they need to know you won't default on the loan. The lender is named on your policy as a loss payee, meaning they get notified if your coverage lapses.

The cost varies widely depending on your location, the age of the building, your deductible, and the replacement value of your belongings. In some markets, condo insurance runs $30 to $50 per month; in others, especially areas with high theft or water damage risk, it can be $100 or more. Older buildings with outdated plumbing or electrical systems often cost more to insure because insurers see them as higher risk.

Key Takeaways

  • HO-6 insurance covers your belongings, interior walls, and personal liability—not the building structure or common areas, which the condo association's master policy covers.
  • Your lender requires proof of condo insurance before closing and must be named on the policy as a loss payee.
  • You need to know what the master policy covers so you can buy the right amount of interior coverage and avoid paying twice for the same protection.
  • Water damage from burst pipes or leaks is often excluded or limited unless you add it, and it is a leading cause of claims in condos.
  • Replacement cost coverage costs more than actual cash value but pays you what it actually costs to replace items, not what they were worth when you bought them.

What the condo association's master policy covers—and what it doesn't

The condo association buys a master insurance policy that covers the building's structure, roof, common hallways, elevators, and shared systems like plumbing and electrical. The association's insurance pays for repairs to those shared parts after a covered loss. However, it does not cover the interior of individual units—that is where your HO-6 policy comes in.

The master policy also has limits. If a major disaster damages the building, the master policy may not cover the full cost of repairs. In that case, the association can assess unit owners for the shortfall. This is called a special assessment, and it can be thousands of dollars. Some condo associations carry extra insurance called loss assessment coverage to protect owners from this risk; some do not. Before buying a condo, ask the association whether they carry loss assessment insurance and what their reserve fund looks like.

Your HO-6 policy should not duplicate what the master policy covers. If you pay to insure the building's roof through your own policy, you are wasting money. When you get quotes, tell the insurance company what the master policy covers so they can price your HO-6 correctly.

Interior coverage: walls, fixtures, and where the line gets blurry

Your HO-6 policy covers the interior walls of your unit, but the definition of "interior" varies by insurer and by condo building. Some policies cover only the drywall and paint; others include built-in cabinets, flooring, and fixtures you installed. The master policy might cover some of these things instead. This overlap is where disputes happen.

Before you buy, ask your insurance agent for a clear list of what is and is not covered. Then ask the condo association or review the master policy to see what they cover. If there is a gap—say, the master policy covers the roof but not the ceiling inside your unit—your HO-6 needs to fill it. If both policies cover the same thing, you are paying twice and will only collect once anyway.

Flooring is a common source of confusion. Some condo policies cover flooring you installed; others do not. If the master policy does not cover it and your HO-6 does not either, a water leak that ruins your hardwood floors leaves you paying out of pocket. This is why asking these questions before you buy is critical.

Water damage: the most common claim and the hardest to get paid

Water damage from a burst pipe, a leak from the unit above you, or a failed appliance is the leading cause of condo insurance claims. It is also the most likely to be denied or limited. Many standard HO-6 policies exclude water damage entirely or cap the payout at $1,000 to $5,000. If you want full coverage, you usually have to add it as a rider, which costs extra.

The master policy may cover water damage that originates in the common areas—a burst pipe in the shared wall, a leak from the roof. But if the water damage starts inside your unit—your washing machine overflows, your toilet backs up—that is your HO-6's job. And if your HO-6 excludes water damage, you are not covered.

Before you buy a condo, especially in an older building, ask the insurance company what water damage coverage costs and what it actually covers. Some policies cover sudden, accidental water damage but not slow leaks. Others exclude damage from poor maintenance. Read the exact language in the policy, not just the summary. Water damage claims can run $10,000 to $50,000 or more, so this is not a place to save $20 a month on your premium.

Replacement cost versus actual cash value

When you get a quote for condo insurance, you will see two options for how claims are paid: replacement cost and actual cash value. Replacement cost means the insurer pays what it costs to replace the damaged item new. Actual cash value means they pay what the item was worth at the time it was damaged, after subtracting depreciation.

If a fire destroys your five-year-old couch, replacement cost might pay $2,000 for a new one. Actual cash value might pay $600, because the couch has depreciated. Replacement cost costs more—sometimes 10 to 20 percent more per month—but it is almost always worth it. After a major loss, you do not want to be arguing about depreciation while you are trying to rebuild.

For your belongings, replacement cost is the standard choice. For the interior of your unit—walls, cabinets, flooring—ask your agent which option is available and what the price difference is. Some insurers offer replacement cost for the structure and actual cash value for belongings, or vice versa. Understand what you are getting before you buy.

Liability coverage and what it protects you from

Your HO-6 policy includes liability coverage, which pays if someone is injured in your unit and sues you. If a guest slips on your floor and breaks their leg, or if your dog bites someone, your liability coverage pays their medical bills and legal costs up to your policy limit. Standard limits are $100,000 to $300,000, though you can buy more.

Liability coverage also covers damage you cause to someone else's property. If you accidentally flood the unit below you, your liability coverage pays for the damage to their unit and belongings. This is why liability coverage matters even if you think nothing bad will happen—water leaks and accidents are common in condos, and one incident can cost tens of thousands of dollars.

Most condo owners carry $300,000 in liability coverage. If you have significant assets or worry about being sued, you can add an umbrella policy on top of your HO-6, which provides an extra $1 million or more in liability coverage for a relatively low cost.

How to shop for condo insurance and what to compare

Start by gathering information about your condo: the year it was built, the number of units, whether it has a doorman or security system, and what the master policy covers. Call your lender and ask if they have any requirements beyond the standard HO-6 minimum. Some lenders require higher liability limits or specific coverage for certain risks.

Get quotes from at least three insurers. When you call, tell them you want HO-6 coverage and provide the building information. Ask for quotes with the same deductible, the same liability limit, and the same coverage options so you can compare apples to apples. Do not just pick the cheapest quote; check the insurer's customer service ratings and claims-handling reputation, because you want to know they will pay when you need them.

Ask each insurer specifically about water damage, loss assessment coverage, and whether they offer replacement cost for the interior of your unit. Write down the answers so you can compare. Once you have chosen a policy, provide proof of insurance to your lender before closing. Your lender will not release the mortgage funds without it.

Special situations: older buildings, high-rise condos, and assessments

Older condo buildings—especially those built before 1980—are harder and more expensive to insure. Outdated plumbing and electrical systems mean higher risk of water damage and fire. Some insurers will not cover buildings over a certain age, or they charge significantly more. If you are buying a condo in an older building, get an insurance quote before you make an offer, because the cost might change your decision.

High-rise condos in urban areas face different risks: higher theft rates, more water damage from shared plumbing, and higher liability exposure because more people live close together. Insurance for a high-rise unit often costs more than for a garden-level condo in the same city. Location matters as much as the building itself.

If the condo association has a history of special assessments—charges to owners for major repairs—your insurance costs will be higher, and you may have trouble finding coverage at all. Before you buy, ask the association how many special assessments they have had in the past five years and what they were for. This tells you whether the building is well-maintained or headed for expensive repairs.

Frequently Asked Questions

Does the condo association's insurance cover damage inside my unit?

No. The master policy covers the building structure, roof, and common areas. Your HO-6 covers your belongings and the interior of your unit. If damage starts in a common area—a leak from the roof or a burst pipe in the shared wall—the master policy pays. If it starts in your unit, your HO-6 pays.

What happens if I do not have condo insurance?

Your lender will not close the mortgage without proof of insurance. If you somehow get a policy after closing and then let it lapse, your lender will buy a force-placed policy on your behalf and add the cost to your mortgage payment. Force-placed policies are expensive and cover only the lender's interest, not your belongings or liability.

Can I use a standard homeowners policy instead of HO-6?

No. A standard homeowners policy (HO-3) is for single-family homes and covers the building structure. Condo buildings have a master policy that covers the structure, so an HO-3 would duplicate that coverage and leave gaps in your personal liability and belongings. HO-6 is designed specifically for condos and is what your lender requires.

Why is water damage so expensive and so often excluded?

Water damage claims are frequent and unpredictable. A single burst pipe can cost $50,000 to repair and replace. Because claims are common and expensive, insurers either exclude water damage, cap it at a low amount, or charge extra to cover it. If you want full water damage coverage, you have to ask for it and pay for it.

Should I buy the highest liability limit available?

Standard liability limits are $100,000 to $300,000. Most condo owners choose $300,000. If you have significant assets or are worried about a lawsuit, an umbrella policy adds $1 million in coverage for $100 to $200 per year, which is cheap insurance against a catastrophic liability claim.
