Who Is Liable for a Water Leak from an Upstairs Unit?
Usually whoever caused it, often the upstairs owner's policy, but your own HO-6 covers your unit's damage regardless of fault.

When the leak is from the unit above you
Fault usually falls on the upstairs owner if the leak came from something they were supposed to maintain, like a washing machine hose or a toilet line. Their liability coverage can pay for damage to your unit and belongings if their insurer agrees they were responsible. But that process takes time, and proving fault isn't always clean, especially with pipes inside walls that both owners could argue aren't theirs. This is why your own HO-6 policy matters regardless of who caused it. Your walls-in coverage pays to repair your unit and your personal property coverage pays for ruined belongings, and your insurer can then pursue the upstairs owner's insurer to recover what it paid. You get your repairs started without waiting on someone else's claim to settle.
An HO-6 with too little walls-in coverage leaves part of the repair bill on the owner even when the upstairs neighbor was at fault, because low limits run out before drywall, flooring, and cabinets are replaced. Comparing policies now shows what different insurers set as a default limit and what it costs to raise it, before a leak forces that decision.
What happens if the upstairs owner has no insurance or fights the claim
Not every upstairs owner carries insurance, and not every insurer agrees to pay. If the owner above has no policy at all, or their insurer denies the claim because fault is disputed, pursuing them directly for repair costs can mean small claims court or a lawyer, and that takes months most people don't have while their kitchen ceiling is caving in. This is the exact gap an HO-6 is built to close. Your insurer pays your claim under your own coverage, repairs happen on your timeline, and the question of who ultimately owes what gets settled between insurers later through subrogation. You are not a bystander waiting on a stranger's claim.
Loss assessment coverage handles a different problem. If the leak started in a shared pipe or a common area wall, the HOA's master policy may take the loss, and the HOA can pass its deductible or an uncovered portion to every owner as a special assessment. A typical HO-6 includes some loss assessment coverage by default, often a few thousand dollars, but a burst pipe behind a shared wall serving several units can generate an assessment well above that. Check the declarations page for the loss assessment limit and raise it if the building has a lot of shared plumbing or an aging system.
Townhomes complicate this further depending on how the property is structured. Some townhome associations carry a master policy similar to a condo building's, covering shared roofs, siding, and structure, with owners insuring the interior. Others treat each townhome as a standalone structure, meaning the owner's policy, closer to a standard homeowners policy than an HO-6, covers the building itself and there is no master policy to fall back on for an upstairs leak. The HOA's governing documents and insurance addendum say which setup applies, and that document matters more than what the building looks like from outside.
Before buying into either a condo or a townhome, ask for the HOA's certificate of insurance and read what the master policy covers, specifically whether it's a bare walls, single entity, or all-in policy. That one detail determines whether your HO-6 needs to cover just paint and carpet or full wall-in reconstruction, and it changes what a reasonable coverage limit looks like for your unit.
What the HOA master policy actually covers versus your own policy
The master policy's type decides where your coverage needs to start, and the three common types leave very different gaps. A bare walls policy covers only the building's structural elements, the studs, floors, and roof. Everything else, including drywall, built-in cabinets, flooring, and fixtures, falls to the unit owner's HO-6. A single entity policy covers more, often including original fixtures and finishes as they existed when the building was built, but not upgrades an owner added later. An all-in policy covers the most, sometimes extending to upgrades and improvements, which means a unit owner needs less walls-in coverage on their own HO-6. Three buildings that look identical from the parking lot can have three different answers to who pays for a flooded kitchen floor.
Two owners in the same building, even the same floor plan, can need very different HO-6 limits because of this. Someone in a bare walls building needs enough walls-in coverage to rebuild their unit from the studs out. That means cabinets, flooring, plumbing fixtures, and built-in appliances, all of it. Someone in an all-in building may only need enough to cover upgrades beyond what the master policy already insures, like a renovated bathroom or custom closets. Buying coverage without knowing which type applies means either paying for overlap the master policy already handles or leaving a gap it was never going to fill.
The HOA's insurance certificate or governing documents state the policy type directly, usually in a section describing what the association insures versus what owners are responsible for. If that language isn't clear, the HOA's board or management company can usually confirm it. It is worth asking before finalizing an HO-6 limit rather than guessing from the monthly dues or the building's age. An HOA that recently changed insurers may also have changed policy types, so confirming matters even for someone who has lived there for years, not just someone buying in.
None of this changes who pays first when water comes through the ceiling. The HO-6 still responds to the unit owner's own damage regardless of fault or master policy type, and loss assessment coverage still matters when a shared pipe or common wall is involved. What the master policy type changes is how much walls-in coverage is enough, a number worth revisiting any time the HOA changes insurers or a renovation adds value inside the unit.
Check these two numbers before the next leak
Find your HO-6's walls-in limit and loss assessment limit on your declarations page, then confirm your HOA's master policy type. Together they tell you whether your current coverage would actually cover a flooded unit.
