Clogged Drain in a Calgary Rental: Who Pays, Tenant or Landlord?
Drain problems in a rental almost always come with a second question attached to the first one: who's actually supposed to pay for this? Alberta's Residential Tenancies Act doesn't spell out "drain cleaning" specifically, but it does draw a reasonably clear line once you understand how it applies.

The Baseline Rule: Normal Wear vs. Tenant-Caused Damage
Under Alberta's RTA, landlords are responsible for maintaining a rental property in a reasonable state of repair — this includes normal-functioning plumbing. That obligation covers issues that arise from age, ordinary use, or factors outside the tenant's control, like root intrusion into an old main line or gradual pipe deterioration.
Tenants are generally responsible for damage caused by misuse or negligence beyond normal wear — pouring grease down a kitchen drain repeatedly, flushing items that clearly don't belong in a toilet, or similar clearly avoidable causes.
The practical test almost always comes down to: would this clog have happened regardless of who was living there? If yes, it's normal wear and a landlord responsibility. If the clog is traceable to something the tenant specifically did that a reasonable person would know not to do, it shifts toward tenant responsibility.

How This Plays Out in Practice
Scenario: Main line backup in a 25-year-old home. This is almost always landlord responsibility — root intrusion and aging pipe are wear-and-tear issues that exist independent of who's renting the unit.
Scenario: Kitchen sink clogged from grease poured down the drain. This leans tenant responsibility if it's clearly traceable to that cause, since pouring grease down a drain is a known, avoidable habit rather than something that happens through normal use.
Scenario: Toilet clogged from flushing something it shouldn't have. Tenant responsibility, generally, for the same reason.
Scenario: A slow drain that's existed since move-in. Landlord responsibility — pre-existing conditions aren't something a tenant caused, and ideally should have been documented in a move-in inspection.

What to Do as a Tenant
Report the issue promptly and in writing (email or text works, so there's a timestamp). Don't attempt aggressive DIY fixes on something you suspect is a pre-existing or structural issue, since forceful attempts on a clog you didn't cause can complicate who's responsible if something breaks. If your landlord is slow to respond and the issue is affecting your ability to use the unit normally, Alberta's Residential Tenancy Dispute Resolution Service (RTDRS) is the appropriate next step, not withholding rent.
What to Do as a Landlord or Property Manager
Document the reported issue and the resolution, and keep receipts from whoever clears the drain — this record protects you if a similar issue comes up again, or if the same unit changes tenants and the timeline of repairs ever needs to be shown. If the clog was clearly caused by tenant misuse, that documentation is also what supports a damage deposit deduction if it comes to that.
