Are Condos Responsible for Plumbing?
Usually, the HOA's master policy covers shared pipes. Your HO-6 policy covers lines serving only your unit.

Where the Pipe Sits
Plumbing inside your walls that serves only your unit is typically your responsibility. Pipes in shared walls, risers, or common areas that serve multiple units usually fall under the HOA's master policy. Your governing documents, not your insurer, draw this line first.
Bylaws Decide the Split
Condo bylaws set the legal boundary between what the HOA must insure and what you own. Some associations cover plumbing up to the wall surface, others go further in. Read the declaration page of the master policy and your bylaws together before assuming where coverage stops.
Water From a Neighbor
When water travels from another unit into yours, your HO-6 pays for damage to your walls, floors, and belongings. The neighbor's policy or the HOA's master policy may cover the source of the leak itself. Fault and source are often handled as separate claims.
The Assessment After a Loss
If a shared pipe fails and damage exceeds what the master policy pays, the HOA can bill every owner a special assessment to cover the gap. Loss assessment coverage on your HO-6 reimburses you for that bill, up to the limit stated on your policy.
A burst riser behind a shared wall can leave every owner in the building splitting a repair bill the master policy didn't fully cover. Without loss assessment coverage, or with too little of it, that bill comes straight out of pocket. HO-6 policies vary widely in how much assessment coverage they include and what a unit actually needs. Comparing policies shows what's covered and what still falls on you.
What About Townhomes and Older Buildings
Townhomes complicate this because ownership structure varies more than it does with condos. Some townhome associations own and insure the exterior walls and roof the way a condo HOA does. Others treat each townhome as a standalone structure, with the owner responsible for everything from the foundation up, including all the plumbing inside and around it. Check whether your association carries a master policy at all. If it doesn't, you likely need an HO-3 policy built for a detached or semi-detached home, not an HO-6, which assumes a master policy exists to cover the structure.
Older buildings add a layer most people don't think about until a pipe fails. A 1960s building with its original galvanized steel plumbing is a different risk than a building re-piped with PVC or copper in the last decade. Insurers sometimes ask about the age and material of the building's plumbing system, and some master policies exclude damage from pipes the association knew were failing but hadn't replaced. If the HOA has deferred plumbing updates, ask whether that affects what the master policy will pay out when something breaks.
How much loss assessment coverage a unit needs depends on the building's size and its master policy's own limits and deductible. A twelve-unit building splitting a large deductible among few owners means each share is bigger than it would be in a two-hundred-unit building. Meeting minutes and the master policy's declarations page both help here. If the master policy carries a high deductible, that gap is exactly what loss assessment coverage on an HO-6 is meant to close.
None of this is written the same way twice. Two buildings next door to each other can split plumbing responsibility at completely different points, depending on when their bylaws were drafted and who drafted them. The only way to know where a specific unit's coverage starts is to read that building's documents, not to assume based on what a similar-looking building down the street does.
Does It Matter If the Leak Was an Accident
Whether a leak was anyone's fault rarely changes who pays first. A pipe bursting inside your neighbor's wall because of age isn't negligence. Someone leaving a washing machine hose disconnected is closer to it. Either way, the insurance response runs the same basic path. Your HO-6 pays for damage inside your unit. The neighbor's policy or the HOA's master policy addresses the pipe itself and may reimburse your insurer later if negligence is found.
Fault matters more when it comes to subrogation, which is the process where one insurer seeks repayment from another after paying a claim. If an investigation finds the neighbor ignored a known leak for weeks, their insurer may end up covering costs your insurer already paid out. That process happens between insurers. It doesn't change how fast your own claim gets paid or whether you need to file one at all. Waiting to find out who's at fault before filing only delays your own repairs.
Negligence can still affect you directly. Repeated claims are the reason why. If your unit floods twice in two years, even from a neighbor's pipe both times, your claims history reflects that regardless of fault. Some insurers weigh frequency of claims more heavily than cause. Asking the HOA whether the building has a pattern of plumbing failures, and whether it's addressing that pattern, tells you something about your own renewal risk even when you weren't the one who caused any of it.
Documentation matters more than blame in the moment. Photos of the damage, a copy of the plumber's report on where the water came from, and the date you reported it to the HOA all help your claim move regardless of whose pipe failed. Save those records before repairs start. If the question of fault comes up later between insurers, that paperwork is what settles it, not anyone's memory of what happened.
Before you insure a unit
Pull the master policy's declarations page and your bylaws. Compare its deductible to your own loss assessment limit. A high deductible and a low limit is the gap you'd owe after a shared pipe fails.
