You just bought your dream apartment—congrats! But now a pipe under the sink is leaking, and you’re wondering: “In an owned apartment unit, is bathroom plumbing my responsibility?” You’re not alone. Many new condo owners face confusion about who handles what when it comes to plumbing repairs. The answer isn’t always straightforward—but we’ll break it down clearly so you can act fast, avoid fines, and protect your investment.
What Exactly Counts as “Bathroom Plumbing”?
Before diving into responsibilities, let’s define the scope. Bathroom plumbing includes:
- Supply lines: Pipes bringing fresh water to your shower, sink, and toilet.
- Drain-waste-vent (DWV) system: Pipes that carry wastewater away.
- Fixtures: Toilets, sinks, bathtubs, showerheads, faucets.
- Shut-off valves: Local valves controlling water flow to individual fixtures.
Generally, anything inside your unit walls or under your floors that serves only your unit is likely your responsibility—unless your governing documents say otherwise.
💡 Pro Tip: According to the Community Associations Institute (CAI), over 68% of plumbing disputes in condos stem from unclear definitions of “exclusive use” vs. “common elements.”
Who’s Responsible: You or the HOA?
This is where most confusion arises. In a condominium (which is what most “owned apartments” legally are), ownership is divided between your unit and common areas managed by the Homeowners Association (HOA).
The General Rule (Based on Most CC&Rs)
| Component | Typically Your Responsibility | Typically HOA’s Responsibility |
|---|---|---|
| Pipes inside your unit walls serving only your unit | ✅ Yes | ❌ No |
| Main vertical stack (shared drain/water line) | ❌ No | ✅ Yes |
| Fixtures (toilet, sink, shower) | ✅ Yes | ❌ No |
| Pipes behind shared walls or under slabs (if shared) | ❌ Depends | ✅ Often |
| Water damage caused by your negligence | ✅ Yes | ❌ No |
⚠️ Important: Always check your Declaration of Covenants, Conditions & Restrictions (CC&Rs) and HOA bylaws. These override general rules.
For example, in California Civil Code § 1364, the owner is responsible for maintaining “all portions of the separate interest,” which usually includes internal plumbing. But in New York, some older co-op buildings assign more responsibility to the corporation.

Real-Life Case: Who Paid for the Burst Pipe?
In 2023, a Miami condo owner ignored a slow drip under their bathroom sink. Two weeks later, the pipe burst, flooding the unit below. The HOA denied coverage, citing the owner’s failure to maintain “exclusive-use plumbing.” The owner ended up paying $12,500 in repairs and legal fees.
Moral of the story? Don’t assume the HOA will cover it—even if the leak affects others. Proactive maintenance is cheaper than emergency fixes.
Step-by-Step: What to Do When You Spot a Plumbing Issue
If you notice a leak, clog, or strange noise in your bathroom plumbing, follow these steps:
- Shut off the water
Locate your unit’s main shut-off valve (usually near the water heater or in a utility closet). Turn clockwise to stop flow. - Document everything
Take photos/videos of the issue, including timestamps. Save receipts for any temporary fixes. - Review your HOA documents
Search for terms like “plumbing,” “maintenance,” “exclusive use,” and “alterations.” - Notify your HOA (if required)
Some bylaws require written notice within 48 hours for leaks that might affect common areas or other units. - Hire a licensed plumber
Use someone insured and familiar with condo regulations. Get a written report—they may need to specify whether the issue originated in your unit or a common element. - File a claim (if applicable)
Check your HO-6 insurance policy (condo owner’s insurance). It typically covers sudden plumbing failures within your unit, but not wear-and-tear.
Common Misconceptions About Plumbing Responsibility
Let’s clear up a few myths:
- ❌ “The HOA pays for all pipes because they own the building.”
→ False. You own your unit’s interior systems unless stated otherwise. - ❌ “If it’s behind the wall, it’s not my problem.”
→ Not necessarily. If the pipe only serves your unit, it’s likely yours—even if hidden. - ❌ “My renter is responsible since they caused the clog.”
→ As the owner, you’re still liable to the HOA. You can seek reimbursement from the tenant later.
How to Prevent Costly Plumbing Disputes
Prevention saves money and stress. Try these best practices:
- Inspect shut-off valves every 6 months – They can seize up if unused.
- Avoid chemical drain cleaners – They corrode pipes over time. Use a plumber’s snake or enzymatic cleaner instead.
- Install leak detectors – Devices like Flo by Moen alert you to leaks in real time.
- Attend HOA meetings – Stay updated on plumbing upgrades or rule changes.
According to the Insurance Information Institute, water damage claims average $11,000 per incident—and 40% of them involve plumbing failures in multi-family homes.
FAQ Section
Q1: Is the main sewer line my responsibility in a condo?
A: Usually no. The main vertical sewer stack is a common element maintained by the HOA. However, the horizontal branch from your unit to the stack is often your responsibility—check your CC&Rs.
Q2: What if a pipe bursts in the wall between my unit and my neighbor’s?
A: This depends on whether it’s a shared supply/drain line. If it serves both units, the HOA typically handles it. If it only serves yours, you’re responsible—even if it’s in a shared wall.
Q3: Does my condo insurance cover bathroom plumbing repairs?
A: Standard HO-6 policies cover sudden and accidental discharge (e.g., burst pipe), but not gradual leaks or lack of maintenance. Always read your policy exclusions.
Q4: Can the HOA fine me for a plumbing issue in my unit?
A: Yes—if your negligence (e.g., ignoring a leak) damages common areas or other units, the HOA can charge you for repairs and impose fines per their governing docs.
Q5: Who pays if tree roots crack a sewer line under the building?
A: If it’s the main line, the HOA pays. If it’s a lateral line exclusive to your unit, you likely pay—even if the damage came from outside.
Q6: Should I get a home warranty for my condo bathroom plumbing?
A: It can help with appliance and fixture failures (e.g., toilet fill valve), but most exclude pre-existing conditions or pipe replacements. Read the fine print carefully.
Conclusion
So—in an owned apartment unit, is bathroom plumbing your responsibility? In most cases, yes, especially for fixtures and internal pipes that serve only your space. But always verify with your HOA documents, because exceptions exist based on location, building age, and association rules.
Knowing your responsibilities protects your wallet, your neighbors, and your peace of mind. Don’t wait for a flood to learn the hard way!
