Splitting Repair and Damage Costs Between Roommates

Roommates & Shared Housing Alberta 4 min read · published March 29, 2026 Flag of Alberta
Living with roommates in Alberta means sharing chores, bills and sometimes repair bills. When something breaks or a part of the rental is damaged, tenants often wonder who should pay, how to document the issue, and when to involve the landlord or a tribunal. This guide explains common rules and practical steps for Alberta renters: how to tell accidental damage from wear and tear, how deposits and lease terms affect who pays, how to gather evidence, and what official forms and dispute routes exist if you can’t agree. It focuses on sensible allocation, clear communication with roommates and landlords, and how to use provincial resources to resolve disagreements fairly.

Who pays for repairs?

In Alberta the general rule is that landlords must maintain basic habitability and make routine repairs, while tenants are responsible for damage they or their guests cause. Check your lease for clauses that assign responsibility for specific items and note that the Residential Tenancies Act sets the legal framework for obligations and remedies.[2]

In Alberta, landlords must keep rental units in a reasonable state of repair under the law.

Common examples

  • If a shared appliance fails from normal use, the landlord usually pays for repairs unless the lease says otherwise.
  • If one roommate causes a hole in a wall or breaks a window, that roommate (or the group, if agreed) typically covers repair costs.
  • Normal wear and tear such as faded paint or worn carpet is not usually charged to tenants as damage.
  • Emergency repairs to prevent further damage should be arranged promptly; the cost allocation depends on fault and lease terms.
Keep dated photos and receipts for any damage or repair work you arrange.

How to divide costs fairly

Start by reviewing the lease and any written roommate agreement. If the lease requires the deposit to cover damage, discuss whether the group will use the deposit or reimburse the responsible person. For detailed rules about security deposits and how they are handled in Alberta, see provincial guidance and consider the deposit rules when apportioning costs.

  • Check the lease for a repairs or maintenance clause before agreeing who pays.
  • Document damage with photos dated and stored by all roommates.
  • Agree in writing who pays and how much; use receipts if someone pays upfront and is later reimbursed.
Written agreements between roommates make cost-splitting clearer and reduce disputes later.

Documenting damage and communicating

Good documentation is your strongest protection. Take photos or video, keep receipts for repairs, and write a short timeline of what happened. Share evidence with roommates and the landlord in writing and keep copies. If a landlord is responsible for a repair, submit the request in writing and follow up if the problem is not fixed in a reasonable time.

Send repair requests by email or text so you have a dated record of communication.

When to apply to the Residential Tenancies Dispute Resolution Service (RTDRS)

If roommates cannot agree about who pays, or if there is a dispute with the landlord over repairs or deductions from a deposit, you can apply for dispute resolution with Alberta's RTDRS. The common form is the "Application for dispute resolution (RTDRS)" available on the provincial forms page; tenants use it to ask the tribunal to decide on who owes repair costs and whether a deposit deduction was lawful.[1]

File an application before you accept unilateral deductions you disagree with.

Practical example

If a tenant damaged a window and the roommates agreed the responsible tenant should pay but that person refuses, one roommate can file an RTDRS application asking the tribunal to order payment and attach evidence like photos, receipts and written statements.

Key Takeaways

  • Always document damage and keep receipts to support any cost claim.
  • Check your lease and any roommate agreement before splitting costs.
  • If you can’t agree, apply to Alberta’s RTDRS with evidence.

FAQ

Who pays if an overnight guest breaks something?
Typically the tenant who invited the guest is responsible; document the incident and discuss payment with roommates, then involve the landlord only if the damage affects habitability.
Can a landlord deduct repair costs from our security deposit without my consent?
A landlord can only deduct for legitimate damage beyond normal wear and tear and must follow deposit rules; you can dispute improper deductions through the RTDRS.[3]
What evidence helps in a dispute?
Clear dated photos or video, repair invoices, written communication, and any written roommate agreements are most helpful.

How-To

  1. Document the damage immediately with photos, video and dated notes.
  2. Talk to your roommates and the landlord, sharing evidence and proposed cost splits in writing.
  3. Try to agree on payment or use the security deposit as the lease allows, keeping receipts.
  4. If you can’t resolve the dispute, file an RTDRS application with evidence and attend the hearing.
