Responsibility for a slab leak in a condo splits along two lines that owners often confuse. The pipe itself belongs to whoever the governing documents assign it to, which usually means the HOA if the line sits in a common area and you if it serves only your unit. The water damage inside your walls is almost always yours to repair, no matter where the pipe runs. Insurance decides who actually pays each bill.
Start With the CC&Rs
Your condo association’s Covenants, Conditions, and Restrictions are the first place to look, and until you have read them, every other answer is a guess. CC&Rs divide the property into defined zones and attach maintenance obligations to each.
Three categories do most of the work. The “unit” or “separate interest” is the space for your exclusive use, usually described as everything from the drywall or studs inward. “Common areas” are shared portions of the property, including the foundation, exterior walls, and main utility lines. “Limited common areas” sit outside your unit’s boundaries but serve only your unit, such as a patio, a balcony, or a plumbing branch line running beneath the slab to your kitchen.
A pipe embedded in the foundation that feeds multiple units is almost certainly a common element, and repair falls to the HOA. A supply line that branches off the main and serves only your unit may be your responsibility, even though it sits under the slab outside your walls. That limited common area category is where most disputes land, because owners assume anything outside their unit belongs to the HOA, and the HOA assumes anything serving one unit belongs to that owner.
When the CC&Rs Are Silent
Many CC&Rs were drafted decades ago and never contemplated slab leaks. They may reference “plumbing fixtures” without saying whether that includes supply lines under the foundation. When the documents don’t answer directly, the board usually interprets them, sometimes with help from the association’s attorney, and that interpretation doesn’t always favor the owner.
In many states, default condominium statutes fill the gaps by assigning the association responsibility for common elements and the owner responsibility for everything inside the unit. Those defaults don’t always clarify where a pipe under the slab falls. Before accepting the board’s reading at face value, it’s worth running the language past a real estate attorney.
The Pipe Is One Bill. The Damage Is Another.
Here is the distinction that catches most condo owners off guard: the party responsible for fixing the pipe is often not the party responsible for repairing the damage the leak caused inside the unit. Even when the HOA is obligated to fix a leaking common-area pipe, the water damage to your flooring, cabinets, and drywall is typically yours. Your unit’s interior, from the walls in, is your domain regardless of where the water originated.
Owners discover a slab leak, the HOA agrees the pipe is in a common area, and the owner assumes the association will cover everything. Then the HOA fixes the pipe and walks away, leaving the owner with thousands of dollars in floor and wall damage. The CC&Rs almost always support that outcome, because they assign interior maintenance to the unit owner regardless of fault.
Which Insurance Pays
Two policies come into play: the HOA’s master policy and your individual condo policy, called an HO-6. Neither one changes who is responsible for ordering a repair. They determine who pays for it.
The HOA’s Master Policy
Master policies come in three varieties, and each draws the line between HOA coverage and owner coverage in a different place.
- Bare walls: The HOA’s policy covers only the building’s structure, meaning the framing, exterior walls, roof, and foundation. Everything from the studs or drywall inward, including flooring, fixtures, and cabinetry, is the unit owner’s responsibility to insure.
- Single entity (original spec): The HOA’s policy covers the structure plus the original fixtures and finishes that came with the unit when it was built. Any upgrades or improvements made since are on the owner.
- All-in: The HOA’s policy covers the structure and all permanent fixtures, including owner improvements. The most coverage sits with the association.
If your HOA carries a bare-walls policy and a slab leak destroys your flooring, the master policy won’t pay a dime for your interior damage even if the pipe was in a common area. Under an all-in policy, the same damage might be covered. You need to know which type your HOA carries before a leak happens, because it dictates how much HO-6 coverage you actually need.
Master policies also tend to carry high deductibles, sometimes $10,000 or more. When a covered claim falls below the deductible, or the association wants to recover the deductible amount, the HOA can pass that cost to unit owners through a special assessment.
Your HO-6 Policy
An HO-6 policy covers your unit’s interior, your personal belongings, and your personal liability. If a slab leak damages your flooring, drywall, or furniture, your HO-6 dwelling coverage and personal property coverage pay for repairs, up to your policy limits and minus your deductible.1Progressive.

Two endorsements matter for slab leaks. Loss assessment coverage reimburses you when the HOA levies a special assessment to cover a master policy deductible or an uninsured loss. Default limits are often just $1,000, which rarely covers a meaningful share of a slab leak repair. You can usually raise this limit to $25,000 or more, and given what slab repairs cost, it’s worth doing before you ever need it. Some HO-6 policies also offer an endorsement that helps cover the cost of accessing a pipe even when the pipe itself is the HOA’s responsibility, since tearing up your floor to reach the slab is damage to your unit.
Subrogation Waivers
If your HO-6 insurer pays for damage caused by a pipe the HOA was supposed to maintain, it may try to recover those costs from the HOA’s policy through subrogation. The insurer steps into your shoes and pursues the party at fault. In practice, many condo declarations and state statutes require a mutual waiver of subrogation between unit owners and the association. If your CC&Rs contain that waiver, your insurer cannot recover from the HOA, and the cost stays on your policy. One more reason to read your CC&Rs before you have a claim, not after.
What to Do the Moment You Suspect a Leak
Speed matters. Mold can start forming on damp drywall and carpet within 24 to 48 hours, and an insurer can reduce or deny your claim if you didn’t take reasonable steps to limit the damage.
Shut off the water supply to your unit immediately if you can. Move furniture, electronics, and personal belongings away from the affected area. Then notify your HOA in writing, not just by phone. An email to the property management company works, but include the date you discovered the leak, what you observed, and photos. Written notice creates a record that protects you if the HOA stalls.
Document everything from the moment you find the leak. Take wide-angle photos to establish the location and close-ups to show severity. Video the area while narrating what you see and hear, including any sounds of running water. Save every utility bill that shows an unusual spike. This documentation matters for both your insurance claim and any dispute with the HOA about who should have acted sooner.
File a claim with your HO-6 insurer promptly, even if you believe the HOA is responsible for the pipe. Your insurer can start covering your interior damage immediately and then pursue the HOA’s insurer if the pipe turns out to be a common-area element. Waiting for the HOA to sort out responsibility before filing your own claim just extends the time your unit sits damaged.
When the HOA Refuses to Act
If the HOA acknowledges a common-area pipe but delays or refuses to repair it, you have options, but you need to follow a process. Put your demand in writing with a specific deadline. Cite the CC&R sections that assign the HOA responsibility for common-area maintenance, and note that the delay is causing ongoing damage to your unit.
Request the HOA’s financial records, including the annual budget and reserve study. Associations are generally required to maintain reserves for common-area repairs, and if those funds exist but aren’t being used, that strengthens your position. If the HOA has been collecting dues for maintenance but neglecting the infrastructure, that pattern is relevant to any formal dispute.
Most CC&Rs require mediation or arbitration before either party can file a lawsuit, and many state condominium statutes impose the same requirement. Check your governing documents for a dispute resolution clause before hiring a litigation attorney. Mediation is faster and cheaper than court, and often more effective for these disputes. If it fails and the CC&Rs or state law allow it, a breach-of-contract lawsuit is the next step. The HOA’s obligation to maintain common areas is a contractual promise in the CC&Rs, and failing to honor it is a breach.
Keep in mind that suing your own HOA means suing an organization you partially fund through your dues. Any legal costs the HOA incurs defending itself may come back to you through increased assessments. That reality makes negotiation and mediation worth exhausting before escalating.
