Does Condo Insurance Cover Water Leaks to the Unit Below?
Usually yes, if the leak started in your unit. Your HO-6 liability coverage pays for that damage.
Free to compare
If water travels from your unit into the one below, your HO-6 policy's loss assessment or personal liability coverage usually pays for the neighbor's repairs, since you're the one responsible for the source. Your own walls-in coverage separately pays to fix the pipe or drywall inside your unit. The split gets harder when the leak starts in a shared wall or a pipe the HOA maintains, since that can shift responsibility back to the master policy. Check your declarations page for your liability limit, and check the HOA's governing documents for which pipes count as common elements.
Liability limits on an HO-6 vary a lot, and a water leak into the unit below can run well past a low one once flooring, drywall and the neighbor's belongings are factored in. Some policies carry $100,000 in liability, others much more, and what's listed on your declarations page may not match what a real repair bill would run. Comparing policies shows what coverage costs at different limits.
Who pays if the pipe is the HOA's responsibility
Not every leak traces back to something inside your walls. Plenty of condo buildings run shared plumbing stacks through multiple units, and the pipe that burst might belong to the building, not to you. When that's the case, the master policy the HOA carries is usually the one that responds first, since the HOA is responsible for maintaining common elements like that shared stack. Your HO-6 may still get involved if your unit's finishes or your neighbor's belongings need replacing and the master policy's coverage runs out or excludes certain things.
Loss assessment coverage on your HO-6 matters here. If the HOA's master policy pays for the shared pipe but the building's bylaws let the HOA pass some of the cost back to unit owners through a special assessment, loss assessment coverage is what picks that up. It typically has its own limit, separate from your liability and walls-in coverage, often a modest amount like $1,000 to $10,000 by default. If your building has a history of assessments after water damage, a higher limit is worth asking about when you compare policies.
The governing documents decide where the line falls, not guesswork. Condo declarations usually spell out which pipes, walls and fixtures count as common elements the HOA insures, and which are limited common elements or part of your unit that you're responsible for. Some buildings draw that line at the drywall. Others draw it differently. Reading that section, or asking the HOA for a copy of the master policy's declarations page, tells you where your HO-6 is expected to start.
Townhomes complicate this further because not all of them are insured the same way. Some townhome communities carry a master policy similar to a condo building, covering the exterior walls and roof while owners insure the interior with something like an HO-6. Others are insured entirely by the individual owner on a standard homeowners policy, with no master policy at all, because each townhome sits on its own lot and the HOA only covers shared land or amenities. Which setup applies changes what your own policy needs to include. It's worth confirming with the HOA before assuming an HO-6 is even the right policy type.
What happens when the leak isn't your fault at all
Everything so far assumes your unit is the source of the water. Sometimes it's the other way around, and the leak starts above you and damages your unit instead. In that case, the owner upstairs is generally the one whose liability coverage or loss assessment coverage responds, the same way yours would if the leak ran the other direction. You'd file the claim through your HO-6 for your own repairs and belongings. Your insurer may then seek reimbursement from the upstairs owner's policy, a process called subrogation that happens between the insurers rather than something you need to manage yourself.
Your own policy pays regardless of fault, which matters more than people expect going in. Walls-in coverage and personal property coverage respond to sudden water damage to your unit whether the source was your plumbing, a neighbor's, or a common pipe, because that's what first-party coverage means. You're not stuck waiting to find out whose fault it was before repairs can start. Figuring out who ultimately pays can take weeks, and living with damaged flooring or drywall during that stretch isn't something most people want to do.
Loss of use coverage matters here too, and it's easy to overlook. If the damage makes your unit unlivable while repairs happen, whether from a leak you caused or one that came from elsewhere, loss of use coverage on your HO-6 pays for a hotel or short-term rental and related costs while the work gets done. The limit is usually a percentage of your personal property coverage, so a unit insured for less overall tends to have less cushion here as well. If a prior leak or a neighbor's account suggests repairs in the building tend to run long, checking this limit before it happens is worth the ten minutes it takes.
Ownership status doesn't change any of this. Whether you own the unit outright or carry a mortgage, a lender typically requires proof of HO-6 coverage at a minimum level before closing. That minimum isn't always enough to match what the HOA's governing documents expect from owners. Comparing policies side by side shows the actual cost difference between a bare minimum and coverage that matches both the lender's requirement and the HOA's expectations, which is usually smaller than people assume.
Before you need it
Pull your declarations page and check two numbers. One is your liability limit, the other is your loss assessment limit. Then compare both to what the HOA's governing documents expect from owners. A mismatch there is worth fixing now.
