Quick answer: A tenant can often have a spouse or partner move in as an occupant without making that person a tenant on the lease. The landlord is not automatically required to add the person as a named tenant. Overcrowding, condominium rules and the true nature of the arrangement may matter.
The RTA does not automatically convert a roommate, spouse or partner into a tenant. LTB Interpretation Guideline 21 explains that payments by an occupant do not alone determine status. Adding a person to the tenancy agreement generally requires agreement.
If the original tenant leaves and transfers possession, the situation may instead be an assignment, sublet or unauthorized occupancy.
Does the landlord have to approve the occupant?
Ordinary additional occupancy is generally different from assignment or subletting. A landlord should focus on lawful occupancy standards and actual conduct rather than an arbitrary guest ban.
Does the partner become responsible for rent?
Not automatically to the landlord. Their responsibilities may arise from an agreement with the tenant unless the landlord accepts them as a tenant or the LTB determines otherwise.
Can rent be increased?
An additional occupant does not itself authorize an unlawful rent increase or new occupancy fee.
What should the tenant do?
- Tell the landlord where required by a lawful condo or building process.
- Keep responsibility for rent and occupant conduct clear.
- Do not promise lease rights the landlord has not agreed to.
- Check occupancy standards and insurance.
What should the landlord do?
- Identify whether the named tenant remains in possession.
- Avoid accidentally representing an occupant as a tenant without understanding the effect.
- Address actual overcrowding, damage or interference through the correct process.
- Document any agreement to add a person to the lease.
Example
A tenant remains in the unit and their partner moves in. That is generally an occupant situation. If the tenant moves away and the partner takes over the entire unit, the legal analysis changes.
