Alberta Deposit Rules (2026)
Alberta allows a security deposit of up to one month's rent. It must be held in an interest-bearing trust account, and returned with interest within 10 days of move-out (or the landlord provides a statement of deductions).
Governing law: Residential Tenancies Act, S.A. 2004, c. R-17.1, s. 17–46

One month maximum
A security deposit may not exceed one month's rent at the time the tenancy starts. It can't be increased later just because rent rises.
Trust account + interest
The deposit must be held in an interest-bearing trust account in an Alberta financial institution. Interest is paid at a rate set by regulation.
Move-in & move-out inspection
Both an inspection report at move-in and move-out are required. Without them, the landlord's right to make deductions is limited.
10-day return rule
Within 10 days of the tenant moving out, the landlord must return the deposit, or provide a statement of account and any remaining balance for deductions.
Allowed deductions
Unpaid rent and the cost of repairing damage beyond normal wear and tear. Routine wear cannot be charged.
Stop tracking Alberta compliance in spreadsheets
Proprietio keeps your leases, deposits, rent increases, and notices province-aware — so you stay onside with the Alberta tribunal without memorizing the Act.
