Condo Insurance Explained: What an HO-6 Actually Covers

A condominium sits in an awkward gap in the insurance world. You own real property, so renters insurance does not fit. You do not own the building, so homeowners insurance does not fit either. What you own is the space inside a set of walls, some proportion of what is attached to those walls depending on documents you probably have not read, and a fractional interest in a building somebody else insures. Condo insurance, written on the form commonly called the HO-6, exists to cover exactly that awkward shape.

This coverage note works through it in the order that actually matters. It starts with the split between the association’s master policy and your own, because nothing else can be sized until you know where the line falls. Then it covers the three master policy types and how each one changes what you need, the building property limit that is not the value of your unit, loss assessment coverage and why the default limit is usually too small, the water damage claims that dominate this property type, and the honest method for arriving at your own numbers. Run those numbers through the home insurance estimator as you read, and the companion above will size an illustrative set of limits from your own inputs.

The short answer: the association insures the building and the common areas; your HO-6 insures the inside of your unit, your belongings, your liability, your additional living expenses, and your share of certain association losses. Which parts of the inside are yours depends on whether the master policy is bare walls, walls-in, or all-in, so the association’s declarations are the document that sets your numbers.

What condo insurance actually is

Condo insurance is a policy that covers a unit owner’s share of a shared building. In the United States it is most commonly written on a standardised form known as the HO-6, which is why the two terms are used interchangeably. The form exists because the standard homeowners policy assumes the insured owns the whole structure and the land it sits on, which is not what a condominium owner owns.

What a condominium owner typically owns, in insurance terms, is an interest in the interior of a defined space plus an undivided share of the common elements. Where exactly that interior begins is not decided by the insurer. It is decided by the condominium declaration and the association bylaws, which are the governing documents recorded when the development was created and amended since. Those documents allocate responsibility for maintenance and for insurance between the association and the unit owners, and the master policy is purchased to match that allocation.

The practical consequence, and the reason generic advice about condo insurance is so unsatisfying, is that the correct amount of coverage is building specific. Two owners with identical units in identical buildings can need very different HO-6 limits because their associations carry different master policies. Anyone sizing a condo policy without reading the association’s declarations page and the relevant section of the declaration is guessing, and usually guessing low.

The split between the master policy and your policy

Every condominium has two layers of insurance and the whole subject is easier once you can see them as layers rather than as one policy with gaps.

The lower layer is the association’s master policy, paid for through your monthly assessments. It typically covers the building structure, the roof, the exterior walls, the common areas such as lobbies, hallways, elevators, pools and parking structures, and the association’s own liability for injuries occurring in those common areas. It generally also covers the association’s directors and officers, and often includes fidelity coverage against misappropriation of association funds. From your perspective it is not something you buy, it is something you already pay for.

The upper layer is your HO-6. It covers whatever the master policy does not: some portion of the interior of your unit, your belongings, your personal liability, your additional living expenses if the unit becomes uninhabitable, and your share of certain assessments.

The two layers are meant to meet without a gap. In practice gaps appear in three places: where the master policy type leaves more to the owner than the owner realised, where the master policy’s deductible is large enough to be passed through to owners, and where a loss exceeds the master policy limits. Each of those is addressed by a specific part of the HO-6, and each is covered below.

The three master policy types

Associations carry master policies of broadly three kinds, and the difference between them is the single largest driver of how much building property coverage a unit owner needs. The industry names are not fully standardised, so treat the labels as a starting vocabulary and read the actual document.

A bare walls policy, sometimes called studs out or original specifications, generally insures the building structure only. Coverage commonly stops at the unfinished interior surfaces, which means drywall, flooring, cabinets, countertops, built-in appliances, plumbing fixtures, and light fixtures inside the unit are the owner’s responsibility. This is the type that leaves owners with the largest exposure and is the one most often discovered too late.

A walls-in policy, often called single entity, generally extends coverage to the interior fixtures and finishes as they were originally installed by the developer. Under this type the association’s policy would typically restore the original standard of finish, and the owner is responsible for upgrades made since, plus belongings.

An all-in policy, sometimes called all-inclusive, generally covers fixtures, finishes, and improvements including those made by owners. It leaves the owner responsible mainly for personal property, liability, and assessments.

The practical instruction is short: request the master policy declarations page from the association or the property manager, in writing, and ask directly which of these it is. If the answer is unclear, ask the association’s insurance agent. That one question does more to size your policy correctly than any amount of general research.

Building property coverage and what it insures

The building property limit on an HO-6, which appears on some forms as Coverage A and on others under names such as building property or unit improvements, insures the physical interior elements of your unit that are your responsibility. Depending on the master policy type, that can include drywall and interior partitions, flooring, cabinetry, countertops, built-in appliances, plumbing and light fixtures, interior doors, and any improvements or upgrades made to the unit.

The most useful way to think about it is as a restoration budget rather than a property value. If a fire damaged the inside of your unit and the association’s policy restored the structure to whatever standard its type requires, the building property limit is what pays to take it from there back to the condition you had. Under a bare walls master policy that is a large job. Under an all-in policy it may be almost nothing.

Two details are worth knowing. The first is that upgrades matter disproportionately: an owner who replaced builder-grade finishes with substantially more expensive ones has increased the restoration cost even if the association’s policy is walls-in, because walls-in typically restores the original standard rather than the upgraded one. The second is that this limit is one of the few on an HO-6 where owners routinely carry too little, because it is invisible day to day and because the number is not obvious. Our note on what dwelling coverage is covers the equivalent concept on a detached house, and the same logic applies here at a smaller scale.

Why the limit is not the value of your unit

This is the most common sizing error on a condo policy and it runs in both directions. A unit that sold for $340,000 does not need $340,000 of building property coverage, because a large part of that price is the land, the location, the share of common elements, and the market, none of which burn down. Insuring to the purchase price means paying for coverage that could never be needed.

The opposite error is more dangerous. Owners who understand that the price is not the number sometimes assume the association’s policy handles everything structural and set the building property limit at the lowest available option, or accept whatever default the insurer offered. Under a bare walls master policy that can leave the entire interior of the unit uninsured.

The right anchor is a restoration estimate: what would it cost, at current local labour and material costs, to rebuild the interior elements you are responsible for, to the standard they are currently finished to. Contractors can estimate this, insurers often have tools that will, and for a rough sanity check a per square foot figure applied to your unit’s area gets you in range. Whatever method you use, revisit it after any significant renovation, because a kitchen replacement can move the number materially. Our note on actual cash value versus replacement cost covers the valuation basis that sits alongside the limit.

The spread in that chart is why the master policy question comes first. An owner who carries $15,000 of building property coverage in a bare walls building is not slightly underinsured, they are underinsured by roughly the cost of the interior of their home.

Loss assessment coverage

Loss assessment is the coverage that exists on condo policies and essentially nowhere else, and it is the one most often carried at a limit nobody chose deliberately. It pays your share when the association levies a special assessment against unit owners following a covered loss.

Assessments of this kind arise in several ways. A loss to a common area may exceed the master policy’s limits, leaving a shortfall the association must raise from owners. The master policy’s deductible, which on larger buildings can be substantial, may be allocated across owners rather than absorbed by reserves. A liability judgment against the association above its coverage can be assessed. And in some situations a loss that the master policy excludes entirely, such as certain water or earth movement events, becomes an owner obligation.

The mechanics matter. Loss assessment coverage typically responds only where the underlying cause of the assessment would have been a covered peril under your own policy, and it has its own limit and often its own deductible treatment. It does not usually cover routine assessments for maintenance, reserve underfunding, or capital improvements, which are association budget matters rather than insurance losses.

Because policies commonly include a modest default limit, and because the exposure is driven by the association’s deductible and its coverage adequacy rather than by anything about your unit, this is a limit worth actively choosing. Ask the association two questions: what is the master policy deductible, and how is it allocated among owners if it is passed through. Then set the limit with those answers in hand.

The master policy deductible pass through

This deserves separating out because it surprises people and because it is the most likely route by which a large building loss reaches an individual owner’s finances. Master policies on substantial buildings frequently carry large deductibles, and in many associations the governing documents permit that deductible to be allocated to unit owners, either across all owners or to the owner in whose unit a loss originated.

The consequences differ by scenario. Where the deductible is spread across all owners, each owner’s share may be manageable but is still real money arriving without warning. Where the documents assign it to the unit of origin, an owner whose water heater failed can find themselves responsible for a five figure deductible on a loss that damaged several units below them.

Two protections exist and both are worth checking. The first is the loss assessment limit discussed above, which is the coverage designed for the spread-across-all-owners case. The second is a specific endorsement some insurers offer covering the unit owner’s responsibility for the master policy deductible, which addresses the assigned-to-the-unit-of-origin case. Neither is automatic, and both depend on the association’s documents, which is why reading them is not a formality. Our note on choosing a home insurance deductible covers the deductible logic on your own policy, which is a separate decision from this one.

Personal property inside a condo

Personal property coverage on an HO-6 works much as it does on any other property policy: it covers your belongings against the perils the policy names, subject to your limit, your deductible, and a set of special limits on particular categories.

Two decisions determine whether it does what you expect. The first is the limit, which should be built from an inventory rather than guessed, because almost everyone underestimates the total replacement cost of what they own by a wide margin. Our walkthrough on creating a home inventory for insurance is the practical method, and photographs of each room with a phone are a serviceable minimum.

The second is the valuation basis. A replacement cost basis pays what it costs to buy an equivalent new item today. An actual cash value basis pays that amount reduced for depreciation, which on a ten year old sofa or television can be a substantial reduction. The premium difference between the two is usually modest relative to the difference in a claim, which our note on actual cash value versus replacement cost sizes properly.

Then there are the special limits. Most policies cap payment for particular categories regardless of your overall limit, commonly including jewelry, watches, furs, firearms, silverware, cash, and collectibles. If you own anything in those categories worth more than the cap, the fix is to schedule it individually, which typically also broadens the perils covered. That is a conversation to have when the policy is written, not after a loss.

Personal liability in a shared wall building

Personal liability coverage on an HO-6 responds if you are legally responsible for injury to someone else or damage to their property. In a condominium that exposure has a specific shape that it does not have in a detached house, because your floor is somebody’s ceiling and your plumbing runs through shared assemblies.

The classic condo liability scenario is water: a supply line, appliance hose, or fixture in your unit fails and the water reaches units below. Depending on the association’s documents and on whether you were negligent, you can be responsible for damage in units you have never entered, and the total across several units can be large.

Other exposures are more familiar: a guest injured in your unit, a dog bite, damage you cause to common property. Liability limits are usually available in steps, and the premium difference between a modest limit and a substantially higher one is typically small, because large liability claims are infrequent. For anyone with assets or income worth protecting, and particularly for anyone in a building where a water loss could reach several units, the higher limit is usually good value.

Above the policy limit, an umbrella policy extends liability coverage across your home and auto policies at once, which our note on umbrella insurance explains. For condo owners the umbrella is worth considering earlier than it is for many homeowners, precisely because of the shared-building exposure.

Loss of use and additional living expense

If a covered loss makes your unit uninhabitable, loss of use coverage, often labelled additional living expenses, pays the extra costs of living elsewhere while it is repaired. That typically covers temporary accommodation, and the increase in ordinary costs such as meals if you have no kitchen, up to a limit and often for a limited period.

Two features of condominium living make this coverage more important than owners expect. The first is that a loss originating elsewhere in the building can render your unit uninhabitable even if your unit itself is barely damaged, because access, utilities, or a shared system are affected. The second is that repairs involving the association, a contractor, and multiple insurers commonly take longer than repairs to a single-family home, because more parties must agree before work starts.

That combination argues for checking both the limit and the duration on your own declarations, since some forms express this coverage as a percentage of another limit and others as a stated amount, and some apply a time cap as well as a dollar cap. Note that if the unit is uninhabitable, your monthly association assessments generally continue regardless, since you still own the unit, which is a cost worth remembering when judging whether the limit is adequate.

Water damage the dominant condo claim

Water is the defining claim pattern in condominium property, and understanding why makes the coverage decisions clearer. Units are stacked, so water travels downward through floors that are also somebody’s ceiling. Plumbing stacks and supply lines are shared assemblies passing through multiple units. Water heaters, dishwashers, washing machines, and refrigerator ice lines sit inside units and fail without warning. And a single failure at three in the morning can affect every unit in a vertical line.

What is typically covered is sudden and accidental discharge: a pipe bursts, a supply hose fails, an appliance overflows. Our note on whether home insurance covers water damage covers the general principle, and our note on plumbing coverage covers the distinction between the damage water causes and the cost of fixing the pipe itself, which are treated differently.

What is typically excluded is as important. Gradual leaks and seepage over time are commonly excluded, on the reasoning that they represent maintenance rather than an accident. Damage from long standing moisture and resulting mold is frequently limited or excluded, which our note on mold coverage explains. Sewer and drain backup is often excluded unless a specific endorsement has been added, and that endorsement is inexpensive and worth having in a building with shared drains. And flood, meaning surface water, is excluded entirely from every standard property form, which is a separate topic below.

Who pays when the water comes from another unit

This is the question condo owners actually ask, and the honest answer has two parts that are often conflated.

The first part is which policy responds to repair your unit. In most cases your own HO-6 responds to sudden and accidental water damage to your unit and belongings, subject to your deductible and the policy’s water terms. That is generally the fastest route to getting your home repaired, and waiting to establish fault before filing is usually a mistake because it delays drying and increases the eventual damage.

The second part is who ultimately bears the cost. That depends on responsibility, which in a condominium is allocated between the unit owner where the failure occurred, the association if the failed component is a common element, and possibly nobody if the failure was genuinely accidental and no negligence exists. Where another party is responsible, your insurer may pursue recovery from them, a process our note on filing a home insurance claim touches on. That happens between insurers and generally does not delay your repair.

The practical instructions are the same in every version of this scenario. Stop the water if you safely can. Photograph and video everything before anything is moved or dried. Report it to your insurer and to the association or property manager immediately, in writing. Keep receipts for anything you spend. And do not assume that because the water came from elsewhere, somebody else’s policy will simply handle it, because the coordination is slower than your drying window.

Flood and earthquake are separate

Every standard property insurance form in the United States excludes flood, meaning water arriving at the property from outside such as surface water, storm surge, or overflow of a body of water. Condo policies are no exception, and neither are association master policies unless flood coverage has been purchased separately.

For a condominium there are two layers to check. The association may or may not carry flood coverage on the building, and in some flood zones a lender will require it. Separately, a unit owner can obtain flood coverage for their own contents and interior. Ground floor and basement level units carry markedly different exposure from upper floor units, which affects both the need and the price. Our notes on flood insurance in high risk areas and on how much flood insurance you need cover the sizing, and our note on what flood insurance costs covers the pricing drivers.

Earthquake is similarly excluded from standard forms and similarly available as separate coverage or an endorsement in most areas where it matters. The same two layer check applies: whether the association carries it on the building, and whether you want it on your own interior and contents. In a shared building, an earthquake that damages the structure can also generate an assessment, which loops back to the loss assessment limit discussed above.

How much condo insurance do you need

Rather than a percentage rule, build the number from four separate estimates. Each one answers a different question and each has a different source.

Building property comes from a restoration estimate for the interior elements you are responsible for, which depends on the master policy type. Under a bare walls policy this is the largest of the four and needs real attention. Under an all-in policy it may be small. A per square foot figure applied to your unit area is a reasonable first pass, refined by a contractor estimate if the number is large.

Personal property comes from an inventory. Walk each room, photograph everything, and total the replacement cost. Nearly everyone who does this properly arrives at a higher figure than they expected.

Personal liability comes from your exposure and your assets. In a shared building the water exposure alone argues for more than the minimum, and the incremental premium for a higher limit is typically small.

Loss assessment comes from the association’s master policy deductible and its coverage adequacy. Ask for both and set the limit accordingly rather than accepting a default.

Then choose a deductible you could actually pay from savings tomorrow, since a high deductible that you cannot fund is a coverage gap in disguise. Our note on how much home insurance you need covers the equivalent process for a detached house, and the home insurance estimator turns your inputs into an illustrative set of limits.

What drives an HO-6 premium

Condo premiums are generally lower than homeowners premiums for a comparable property value, because the largest and most expensive part of the structure is insured by somebody else. Within that, the same broad factors apply as on any property policy.

The limits you choose drive the largest share, particularly building property and personal property. The deductible you choose moves the premium meaningfully in the opposite direction. Location matters through the perils that region faces and through local rebuilding costs. The building itself matters through its age, construction type, and protective features such as sprinklers and monitored alarms, and through its claims history in some markets. Your own claims history and, in most states, your insurance credit-based score can affect the rate. Coverage choices such as replacement cost on contents, sewer backup endorsement, scheduled items, and a higher liability limit each add to the total.

Two condo-specific factors are worth knowing. Buildings with a poor claims record, particularly for water, can be harder or more expensive to insure. And associations whose master policy carries a very large deductible push more exposure onto owners, which shows up in the loss assessment limits owners need rather than in the base premium.

Our notes on why home insurance went up and why home insurance is so expensive cover the wider market pressures affecting all property lines, and they apply here too.

How to lower a condo premium sensibly

The levers are broadly the same as on any property policy, with condo-specific notes on each. Raising the deductible reduces the premium and is sensible if the higher amount is genuinely payable from savings. Bundling with an auto policy commonly earns a discount. Protective device credits for monitored alarms, sprinklers, and water leak detection are worth asking about, and leak detection in particular is well matched to the dominant condo claim type.

Shopping the policy periodically is the largest single lever for most people, because renewal pricing drifts. Our walkthrough on switching home insurance covers doing it without a coverage gap, and our note on lowering your premium covers the full list of levers.

Two things to avoid. Do not reduce the building property limit to save premium without first confirming the master policy type, because that is the limit most likely to be tested by a real loss. And do not drop loss assessment coverage to a token limit, because it is inexpensive relative to the exposure and it addresses the one risk that is genuinely unique to owning in a shared building. Small claims are also worth thinking about, since filing frequently can affect renewal pricing, a dynamic our note on insurance increases after a claim covers.

Condo versus renters versus homeowners

Placing the three side by side clarifies what an HO-6 is for.

Renters insurance covers a tenant’s belongings, personal liability, and loss of use. It contains no structural coverage at all, because a tenant owns none of the building, and no loss assessment coverage, because a tenant is not subject to association assessments. Our note on renters insurance covers it properly. If you own a condominium and are carrying a renters policy, the interior of your unit and your assessment exposure are almost certainly uninsured.

Homeowners insurance covers a whole structure, other structures on the lot, personal property, liability, and loss of use. It assumes the insured is responsible for the entire building, so its dwelling limit is sized to rebuild the house from foundation up.

Condo insurance sits between them. It has a structural component like a homeowners policy but sized only to the interior elements the owner is responsible for, plus the loss assessment coverage neither of the other two carries. That middle position is why it is so often bought at the wrong size: people who think of it as renters insurance carry too little building property, and people who think of it as homeowners insurance sometimes insure the purchase price.

What a lender requires at closing

If the unit is financed, the lender will require evidence of insurance before closing, and for a condominium that generally means two documents rather than one.

The first is evidence of your own HO-6 policy, often with a minimum building property limit specified by the lender, sometimes expressed as a percentage of the loan amount. The second is a certificate of insurance for the association’s master policy, showing the building is insured and often showing specified minimum coverage. That second document has to come from the association or its insurance agent, and obtaining it can take days, which is why it is worth requesting early rather than in closing week.

Some loan programs also have requirements about the association itself, such as its reserve funding, owner-occupancy ratio, or litigation status, which are separate from insurance but surface at the same moment. Ask your lender for its condominium requirements at the start of the process.

Practically, the insurance to buy for closing should be the insurance you actually want rather than a minimum policy assembled quickly to satisfy a deadline. It is far easier to size the limits properly once, using the association documents you should be reading anyway during the review period, than to rework the policy later. Our walkthrough on choosing home insurance covers the comparison process, and reading your declarations page once it is issued confirms you got what you asked for.

Reading the association documents

Everything in this coverage note comes back to two documents, and it is worth knowing exactly what to ask for.

The first is the master policy declarations page. Request it in writing from the association or property manager. Look for the type of coverage on the building, the policy limits, the deductible, whether there is a separate and higher deductible for water losses, and whether flood or earthquake coverage is present.

The second is the condominium declaration and bylaws, specifically the sections on insurance and on maintenance responsibility. These allocate who insures and who maintains what, and they contain the language that decides whether a master policy deductible can be passed through to owners and on what basis.

Read them with three questions in mind: where does the association’s insurance responsibility stop, what is the deductible and who pays it, and can I be assessed and in what circumstances. The answers set your building property limit, your loss assessment limit, and whether you want a master policy deductible endorsement. Every general article about condo insurance, including this one, is a substitute for information that is sitting in those two documents.

Common condo insurance mistakes

• Not knowing the master policy type. It changes the building property need by a wide margin, and it is a single question to the association.
• Insuring the purchase price. The land, the location, and the share of common elements are not at risk, so the building property limit is a restoration estimate, not a market value.
• Accepting the default loss assessment limit. It is the coverage unique to this property type, it is inexpensive, and the exposure is set by the association’s deductible rather than by anything about your unit.
• Carrying a renters policy on an owned unit. It leaves the interior and the assessment exposure uninsured entirely.
• Ignoring the water endorsements. Sewer and drain backup is often excluded by default, and in a shared-drain building it is the endorsement most likely to be needed.
• Not updating after a renovation. New finishes raise the restoration cost, and under a walls-in master policy the upgrades are specifically your responsibility.
• Choosing a deductible you cannot fund. A deductible that exceeds your accessible savings converts a covered loss into an out of pocket problem.

Each of these comes from treating a condo policy as a smaller version of something else rather than as the specific instrument it is.

A worked example from documents to limits

Theory into practice on illustrative figures throughout. Our owner buys a 1,200 square foot unit on the fourth floor of a mid-rise building for an illustrative $340,000. During the review period she requests the master policy declarations and the insurance section of the declaration.

The master policy turns out to be bare walls, and its deductible is an illustrative $25,000, allocable across all owners under the declaration. Those two facts set two of her four numbers immediately.

For building property she works from a restoration estimate for the interior of a 1,200 square foot unit finished to a mid-range standard, landing at an illustrative $75,000. She has not renovated, so no upgrade adjustment is needed yet. For personal property she photographs each room and totals replacement cost at an illustrative $45,000, which is more than she guessed before doing it. For liability she takes an illustrative $300,000 rather than the minimum offered, because she is above three other units and the incremental premium is small. For loss assessment she takes an illustrative $50,000 rather than the low default, sized with the association’s $25,000 deductible and the possibility of a shortfall on a larger loss in mind.

She adds a sewer and drain backup endorsement, elects replacement cost rather than actual cash value on contents, schedules an engagement ring that exceeds the jewelry special limit, and picks a $1,000 deductible because that is an amount she can pay from savings tomorrow. Loss of use comes through at an illustrative $15,000. Her declarations page arrives and she checks that every one of those choices appears on it, which is the step most people skip.

Two years later she renovates the kitchen. She calls her agent and raises the building property limit, because under a bare walls master policy every dollar of that renovation is hers to insure. Run your own version of this in the home insurance estimator, and use the companion above to see how the four limits move against each other.

The bottom line

Condo insurance covers what the association’s master policy does not, which means the correct amount of it cannot be worked out from anything on your own declarations page alone. Start with the association: request the master policy declarations, establish whether it is bare walls, walls-in, or all-in, and find out what its deductible is and whether the governing documents allow it to be passed through to owners. Those answers set your building property limit, which is a restoration estimate for the interior you are responsible for rather than the price you paid, and your loss assessment limit, which is the coverage unique to shared-building ownership and the one most commonly left at a default nobody chose. Build personal property from an inventory, take more liability than the minimum because a failed supply line in a stacked building can reach several homes, add the sewer and drain backup endorsement, and pick a deductible you could pay tomorrow. Then revisit the building property limit after any renovation, because upgrades are specifically yours under most master policy types. Size it in the home insurance estimator, read the two association documents once rather than never, and the awkward middle position of condominium ownership becomes a policy that actually fits it.

This coverage note explains how condominium insurance and the HO-6 form commonly work in the United States and is general information only, not insurance, legal, or financial advice. Every dollar figure, percentage, square footage, and limit used here is illustrative and chosen to show the arithmetic, and none of it is a quote, a price, a market rate, or a recommendation for any real unit or building. Policy forms, named perils, exclusions, endorsements, loss assessment terms, and the treatment of master policy deductibles vary by insurer, by policy, and by state, and association responsibility is set by each condominium’s own recorded declaration and bylaws rather than by any general convention. Read your own declarations page, request the association’s master policy declarations and governing documents, and speak with a licensed insurance agent before selecting or changing any limit described here.
