Can My Landlord Charge Me for Clogged Drains? It Depends on Proof

Last updated: March 12, 2026Reviewed for accuracy by a licensed attorney

The sink backed up, the bathtub won't drain, or the toilet keeps clogging. Your landlord called a plumber and now wants to deduct the bill from your deposit. Is that fair? The answer depends entirely on what caused the clog — and whether the landlord can actually prove it. Here's the complete guide.

The General Rule

Tenant-caused clogs (hair, grease, flushing improper items) may be chargeable. But the landlord must prove the cause. A drain clearing invoice alone is not enough — the plumber must identify what caused the blockage. Structural issues like old pipes, root intrusion, and pipe corrosion are always the landlord's responsibility.

What Caused the Clog? That's the Only Question That Matters

Every drain clog dispute comes down to identifying the root cause:

The Key Issue: Proving the Cause

This is where most landlord drain claims fall apart. To charge you, the landlord needs more than just a plumber's bill:

Court perspective: Courts consistently require the landlord to prove causation, not just occurrence. The fact that a drain clogged during your tenancy does not, by itself, prove you caused it. Drains can clog from years of accumulated buildup, aging pipes, or external factors. Without a plumber's specific finding of tenant-caused blockage, courts typically deny the deduction.

The Grease Gray Area

Grease-related clogs are the most disputed category because there's a spectrum:

Clearly tenant's fault: Pouring cooking oil, bacon grease, or other fats directly down the drain. This is misuse and chargeable.

Gray area: Gradual grease buildup from washing dishes over a long tenancy. Normal cooking and dishwashing inevitably sends some grease down the drain. Over years, this can contribute to clogs — but it's arguably normal use of the kitchen.

Clearly landlord's responsibility: Grease buildup in pipes that predates your tenancy, or buildup in shared plumbing lines in a multi-unit building where multiple tenants contribute to the same drain system.

What If Your Landlord Charges You for a Clogged Drain?

If your landlord deducted from your security deposit for drain issues, here's what to do:

Remember: if your landlord wrongfully withheld your deposit, many states impose penalty damages — often double or triple the amount wrongfully withheld.
