My Condo Leaked Into the Unit Below: Am I Responsible?

The Short Answer: It Depends on What Failed

Your downstairs neighbor knocks: water is coming through their ceiling, and it seems to be from your unit. The first worry is the bill.

You are not automatically responsible just because the water started in your unit. Four things usually decide it:

1. What failed. A shared riser or drain stack in your wall is usually a common element the association maintains. A toilet supply line, dishwasher hose or individual water heater is usually yours.
2. Whether you were careless. In many places, an owner is not automatically liable for a sudden failure they could not have known about. Leaving a tub running, ignoring a known drip or a renovation done badly is different.
3. What your declaration says. Some declarations make the owner of the unit where a leak starts responsible for damage to other units and common elements, whether or not anyone was careless. Others only do so when the owner was negligent.
4. How the insurance lines up. Your HO-6 liability coverage, the neighbor’s HO-6 and the master policy may all be involved, and the master policy deductible may be assigned to you.

This is the same leak seen from the other side of the ceiling. Our guide to water leaking from the condo above walks through the downstairs owner’s view.

What to Do Right Now

1. Stop the water. Shut the valve at the fixture or your unit’s main shutoff. If you cannot find it, call the association’s emergency line.
2. Turn off power to anything wet at the breaker if water is near outlets or light fixtures, in your unit or below.
3. Tell the association in writing the same day: what you found, when, and what you did. Ask it to check whether a common element is involved.
4. Call your HO-6 insurer and report it, even if you are not sure you are at fault. Your policy may require prompt notice.
5. Get a written finding of what failed from the plumber. Keep the failed part if you can, such as the split supply line.
6. Take dated photos of the source and your own damage, and ask the neighbor if you can photograph theirs.
7. Give the neighbor your insurer’s name and claim number. It moves things along and shows good faith.

Typical Patterns

Your declaration and state law can change any row.

The Master Policy Deductible

If the association files a master policy claim for building damage, someone pays the deductible. Some declarations assign it to the unit where the leak started, which can mean a large bill even for an accident. Others split it among damaged units or treat it as a common expense. Loss assessment coverage on your HO-6 may pay your share up to its limit. See HOA insurance deductibles.

State law can decide this too. Two examples from our state guides:

• In Florida, repairs to insured property are a common expense, including the deductible, but an owner pays when the damage came from that owner’s (or a family member’s or tenant’s) intentional conduct, negligence or rule violations. See Florida condo law.
• In Colorado, the association may adopt written deductible policies, charge deductibles to negligent owners, and split a deductible among damaged units when a loss affects more than one unit. See Colorado condo law.

What to Check in Your Documents

Step 1: Find out what failed, in writing. This decides almost everything.

Step 2: Check whether that part is a common element. Search your declaration for “common elements,” “pipes,” “fixtures” and the definition of the unit. Our plumbing leaks guide shows where the line usually falls.

Step 3: Look for a section on damage to other units. Search for “damage to other units,” “originates,” “negligence” and “chargeback.” Note whether it requires negligence.

Step 4: Find the deductible allocation rule in the declaration or a board resolution.

Step 5: Read your HO-6. Check your liability limit, loss assessment limit, water backup coverage and any gradual leak exclusion.

Step 6: Ask the board for its decision in writing, with the section it relies on, before you pay any chargeback. Our letter to the condo board asking them to repair leak damage shows how to ask.

Practical Examples

Example 1: Your Dishwasher Hose Splits While You Are at Work

Water runs for hours and soaks the ceiling below. The hose is your appliance. If your declaration makes the source unit responsible, or if the hose was visibly worn, you may owe for the damage below. Your HO-6 liability coverage usually handles that, and your own floor and cabinets go under the property part of your policy.

Example 2: The Plumber Finds a Leak in the Stack Inside Your Wall

The stack serves every unit in your column. It is usually a common element, so the association should repair it. Ask the association in writing to confirm it, and to tell you how the master policy deductible will be handled. You should not be charged as the “source unit” just because the pipe runs through your wall, unless your declaration clearly says so.

Example 3: A Slow Leak Under Your Shower Nobody Knew About

The neighbor finds a stain that has been growing for months. Insurance often excludes gradual leaks, and who pays may turn on whether you knew about it. Report it as soon as you learn of it, fix the source quickly and keep the plumber’s dated finding.

Find Out Who Pays for Your Leak

The free tool at the top of this page asks five questions and shows who usually pays and which documents decide it. Choose “Inside my unit” for where it started. The letter pack then fills in a letter to the board, a letter to the other owner, an evidence and cost log, and a deadline checklist with your answers. You can also open the who pays tool on its own page.

Frequently Asked Questions

Am I responsible if my condo leaks into the unit below?

Not automatically. If a common element like a shared riser failed, the association usually handles it. If something you own failed, you may be responsible for the damage below if you were careless or if your declaration makes the unit where the leak started responsible. Your HO-6 liability coverage often pays damage you owe to a neighbor.

Does my HO-6 cover damage to my neighbor's unit?

Usually the liability part of your HO-6 responds when you are legally responsible for damage to someone else's property, up to your limit. It does not usually pay just because water came from your unit if you were not responsible. Call your insurer right away and give the neighbor your claim number.

Can the HOA charge me the master policy deductible for a leak from my unit?

Sometimes. Some declarations or board resolutions assign the deductible to the unit where the leak started, and some states allow charging it to a negligent owner. Ask for the exact section in writing. Loss assessment coverage on your HO-6 may pay your share up to its limit.

What if the leak came from a pipe inside my wall?

Find out what the pipe serves. A vertical riser or drain stack that serves several units is usually a common element the association maintains, even inside your wall. A branch line that serves only your unit is often yours from the shutoff valve to the fixture. Your declaration sets the exact line.

Should I pay my neighbor directly for the damage?

Be careful. Do not agree to pay before you know what failed and what your insurer and declaration say. If you are responsible, your HO-6 liability coverage may handle it. A small claim you choose to pay yourself is your call, but talk to your agent first.
