Roommate rental laws in Alberta: what tenants need to know

This guide covers Alberta tenancy law only. For other provinces, see our [rental laws guides].

In Alberta, the rules around shared housing and roommates fall under the Residential Tenancies Act. Understanding how different arrangements are treated helps everyone in a shared rental know where they stand legally.

What Are the Main Types of Roommate Arrangements?

Co-tenants: Two or more people who have all signed the same lease. Each co-tenant is equally and fully responsible to the landlord for the rent and the condition of the unit.

Occupants: One person has signed the lease and allows another person to live in the unit. The occupant pays rent to the named tenant and has no direct legal relationship with the landlord.

Subtenants: The named tenant temporarily vacates and allows another person to occupy the unit for a period while the original lease remains in effect. Subletting in Alberta requires the landlord's consent, which cannot be unreasonably withheld for fixed-term leases, according to the Residential Tenancies Act.

Do You Need the Landlord's Permission to Add a Roommate?

To add someone to the lease as a co-tenant, the landlord's agreement is required. For sublets specifically, landlord consent cannot be unreasonably withheld. Alberta does not have specific legislation governing a tenant's right to have an occupant without the landlord's knowledge, so tenants should review their lease carefully for any occupancy restrictions and discuss any changes in household composition with their landlord.

What Is a Roommate Agreement?

A roommate agreement is a private document between housemates covering rent splits, utilities, shared spaces, and house rules. It is not a lease and does not affect the relationship between the named tenant and the landlord. Having one in place helps prevent disputes between housemates and provides a record of agreed arrangements.

What Protection Does an Occupant Have?

An occupant who is not on the lease has no rights under the Residential Tenancies Act against the landlord. If the named tenant is evicted or the lease ends, the occupant has no independent legal standing to remain.

How Are Disputes Between Roommates Resolved?

The RTDRS handles disputes between landlords and tenants, but not between roommates directly. Disputes between roommates about rent splits or shared costs would typically be handled through a civil claim in small claims court, supported by a roommate agreement if one exists.
