Condo Water Heaters: Who Pays for Replacement and Leak Damage?
Who replaces a condo water heater, and who pays when one leaks into the unit below? Learn the typical HOA vs owner split for tanks, central systems, and damage.
Quick answer
If the water heater serves only your unit, you usually pay to repair or replace it, and you may be responsible for leak damage it causes. If the building uses a central boiler or shared system, the HOA usually maintains it. Vents and flues through the roof or exterior walls are often HOA items, so check your CC&Rs.

What Most People Assume vs. What Is Actually True
Water heaters do not get much attention until they fail. Then they get a lot of attention, because a failed tank can dump dozens of gallons of water onto the floor in a short time. In a condo, that water does not stay put. It runs under walls, into hallways, and through the ceiling of the unit below.
Many owners assume the water heater is part of the building, like the pipes in the walls, so the HOA must handle it. Others assume it is theirs, but that the HOA’s insurance will cover any damage it causes. Both assumptions can be expensive.
Here is the typical reality:
- An individual water heater that serves only your unit is usually your responsibility. You maintain it, repair it, and replace it at your cost. This is one of the more consistent patterns in condo documents.
- A central water heating system that serves the whole building is usually the HOA’s responsibility. That includes boilers, large storage tanks, recirculation pumps, and the main distribution lines.
- Damage caused by a failed individual water heater often comes back to the owner. Depending on your CC&Rs and the facts, that can include damage to your own unit, to neighboring units, and to common elements.
- The parts that pass through the building shell are often a gray area. Gas vents, flues, and combustion air openings that run through the roof or exterior walls may be common elements even though they serve your heater.
The biggest risk is not the cost of a new water heater. It is the cost of the damage an old one can do when it fails. Many associations have responded by adopting rules about water heater age, drain pans, or leak sensors. If your building has one of those rules and you ignore it, you may have a harder time arguing you were not at fault.
If Your Water Heater Is Leaking Now
Turn off the cold water supply valve on top of the tank. Turn off the power at the breaker for an electric heater, or set a gas heater’s control to off or pilot. Then call the HOA so they can check for water in the unit below or in common areas. Take photos before cleanup.
Key Terms You Need to Know
- Individual (in-unit) water heater: A tank or tankless heater that serves only one unit. Usually located in a closet, utility room, or garage attached to the unit.
- Central water heating system: Boilers, storage tanks, and pumps that make hot water for many units. Common in high-rises and some mid-rise buildings.
- Tankless water heater: A unit that heats water on demand without a storage tank. It can still leak, but it holds far less water than a tank.
- Drain pan: A shallow pan under the tank that catches small leaks and, ideally, drains to a safe location. Some buildings require one.
- T&P relief valve: The temperature and pressure relief valve on the tank. It opens to release pressure if the tank gets too hot or too pressurized. Its discharge pipe must go somewhere safe.
- Expansion tank: A small tank that absorbs pressure changes in the hot water system. Often required by local code in certain plumbing setups.
- Flue or vent: The pipe that carries exhaust gases from a gas water heater to the outside. When it passes through the roof or an exterior wall, the section in the building shell may be a common element.
- Leak detector or automatic shutoff valve: A device that senses water and alerts you, or shuts off the supply. Some associations require or recommend these.
- Useful life: How long a water heater is expected to last. Tank heaters are commonly expected to last roughly a decade or so, though this varies with water quality, maintenance, and model.
Typical Responsibility Patterns
The table below shows how water heater responsibility is commonly split. Your CC&Rs may assign parts of this differently.
| Component | HOA Typically Responsible | Owner Typically Responsible | Notes |
|---|---|---|---|
| Individual tank or tankless heater | No | Yes | Serves one unit |
| Drain pan and pan drain line | Rarely | Yes | Some rules require a pan |
| T&P valve and discharge pipe | Rarely | Yes | Part of the heater installation |
| Expansion tank (individual) | Rarely | Yes | Serves one unit |
| Supply and hot water lines from the heater to fixtures | No | Yes | Unit branch plumbing |
| Cold water supply riser feeding the unit | Yes | Rarely | Common element up to the unit shutoff |
| Gas line from building main to unit | Usually | Sometimes | Varies by building and utility |
| Flue or vent through roof or exterior wall | Often | Sometimes | Building shell penetration |
| Central boiler or hot water plant | Yes | No | Serves many units |
| Recirculation pumps and central hot water lines | Yes | No | Common element |
| Damage to own unit from individual heater | Rarely | Yes (usually via HO-6) | Owner’s equipment |
| Damage to other units from individual heater | Varies | Often | Depends on CC&Rs and fault |
| Damage from central system failure | Yes | Rarely | Usually master policy or HOA |
Owner Equipment, Owner Risk
The general logic in most CC&Rs is simple: if equipment serves only your unit, you maintain it, and you bear more of the risk when it fails. That logic is why many owners with older tanks are surprised to receive a bill for damage to the unit below, or a chargeback for a master policy deductible.
Building Rules You May Have Agreed To
Many associations adopt rules or policies about individual water heaters. Common examples include:
- Replacing tank heaters at or before a set age
- Requiring a drain pan or leak detector
- Requiring a licensed plumber and a permit for replacement
- Notifying management before replacement so they can confirm venting and access
- Restricting tankless conversions that need new exterior venting
These rules are usually found in the rules and regulations, not the CC&Rs. Ask management for the current version.
Decision Tree: Where to Check in Your Documents
Step 1: Identify the system type. Do you have your own water heater, or does hot water come from a central plant? If you are not sure, look for a tank or tankless unit in a closet, utility room, or garage. If there is none, your building likely has a central system.
Step 2: Search your CC&Rs for “water heater,” “hot water,” “fixtures,” “appliances,” and “equipment serving a single unit.” Many CC&Rs assign anything that exclusively serves one unit to that owner. Some name water heaters directly.
Step 3: Check the rules and regulations. Look for age limits, pan requirements, leak sensors, and contractor rules. Note the date the rule was adopted.
Step 4: Find the provision on damage caused by owner equipment. Search for “damage to other units,” “originates,” “negligence,” and “chargeback.” This decides whether you may owe for damage to neighbors or common areas.
Step 5: Check how vents and flues are classified. If your heater vents through the roof or an exterior wall, check whether the section in the building shell is a common element. Look at the roof and exterior wall sections of your documents.
Step 6: Review your HO-6 and the master policy deductible rule. Sudden tank failures are often covered by insurance. Gradual leaks often are not. If the master policy deductible can be charged to you, make sure your HO-6 has enough loss assessment coverage. See HOA insurance deductibles.
Practical Examples and What to Ask Your HOA
Example 1: Your Tank Fails and Floods the Unit Below
Your 14-year-old tank rusts through at the bottom. Water soaks your floors and pours into the unit below. The HOA sends you a letter saying you are responsible for all damage.
Before you accept that, ask:
- “Which CC&R section makes the owner responsible for damage from equipment serving a single unit?”
- “Does the provision require negligence, or does it apply to any failure?”
- “Was there a rule in effect requiring replacement by a certain age? When was it adopted and how was it communicated?”
- “Is the master policy responding to the claim? If so, how much of the deductible is being assigned to me?”
Call your HO-6 insurer right away. Your liability coverage may respond to damage in the neighbor’s unit, and your policy may cover your own floors. The neighbor’s own HO-6 may also be involved. See leaks from the unit above for how this looks from the other side.
Example 2: The Building’s Central Boiler Stops Making Hot Water
Every unit in the building loses hot water on a cold morning. Management says the central boiler needs a major repair.
This is almost always an HOA responsibility. Ask:
- “Is the boiler listed in the reserve study, and what is its remaining useful life?”
- “Is this repair being paid from reserves or the operating budget?”
- “Is a full replacement being considered, and could that lead to a special assessment?”
Check the reserve study. An aging central plant with little money set aside is a common source of special assessments.
Example 3: You Want to Switch to a Tankless Heater
You want to replace your tank with a tankless gas unit. The installer says it needs a new vent through the exterior wall.
Even though the heater is yours, the wall is probably a common element. Ask:
- “Do I need architectural approval to add a new exterior penetration?”
- “Who will be responsible for maintaining the new vent and any leaks around it?”
- “Does the HOA have approved contractors or specifications for exterior work?”
Get approval in writing before work starts. Unapproved changes to common elements can lead to removal at your expense.
Example 4: The Flue Leaks Rainwater Into Your Closet
Water shows up in your utility closet only when it rains. A roofer finds that the flashing around your water heater flue on the roof has failed.
The heater is yours, but the roof flashing may not be. Ask:
- “Is the roof flashing around unit vents treated as part of the roof, which the HOA maintains?”
- “Will the HOA repair the flashing and the resulting closet damage?”
A Cheap Way to Lower Your Risk
A drain pan with a proper drain line, a leak detector, or an automatic shutoff valve costs far less than a flooded ceiling below. Check the label on your tank for the manufacture date. If it is getting old, plan a replacement before it chooses the timing for you.
Track Your Water Heater Responsibility
Water heaters cross several boundaries at once: owner equipment, common element vents, shared supply lines, and the insurance rules that apply when something leaks. Writing down how your documents treat each piece saves time when something goes wrong.

Frequently Asked Questions
Is the HOA responsible for replacing my condo water heater?
Usually not, if the water heater serves only your unit. Most CC&Rs treat equipment that exclusively serves one unit as the owner's responsibility. If your building uses a central boiler or shared hot water system, the HOA usually maintains and replaces that system. Check your CC&Rs for water heater language or a general rule about equipment serving a single unit.
Who pays if my water heater leaks into the unit below?
It depends on your CC&Rs, the cause, and your insurance. Many associations hold the owner of the leaking equipment responsible for resulting damage, sometimes only if the owner was negligent. Your HO-6 liability coverage may respond to damage in the neighbor's unit, and the master policy may cover parts of the building. The master policy deductible may also be assigned to you. Call your insurer right away.
Can my HOA require me to replace my water heater at a certain age?
Many associations adopt rules like this, and they are often enforceable if the board followed the proper rulemaking process in your documents and state law. Ask management for the written rule and when it was adopted. Even if you question the rule, ignoring it can make it harder to argue you were not at fault if the old tank later fails.
Who maintains the water heater vent or flue on the roof?
Often the HOA maintains the part that passes through the roof or exterior wall, including the flashing, because it is part of the building shell. The owner usually maintains the vent pipe and connections inside the unit. Some CC&Rs assign the entire vent to the owner. Check your documents, especially if a leak appears around the flue during rain.
Does homeowners insurance cover a failed condo water heater?
An HO-6 policy often covers sudden water damage caused by a failed water heater, such as damage to your floors, cabinets, and belongings. It usually does not pay to replace the worn-out water heater itself, and it may not cover damage from slow leaks that went on for a long time. Review your policy and ask your agent about water damage limits and exclusions.
