An accessory apartment—commonly known as basement apartment or in-law suite—is permitted in most single-detached and semi-detached houses in Guelph’s R1, R2, CBD2 and OR zones.
To be considered legal, the apartment must be inspected and registered by the City as a two-unit house. To become registered, the property must meet the requirements of the City of Guelph Zoning Bylaw and, either the Ontario Building Code or the Ontario Fire Code, as determined by City of Guelph Building Services.
Register a two-unit house
A $150.00 one-time registration fee is required at the time of submitting the registration form. If construction has started without a permit, the registration fee is $300.00.
If it is determined that a building permit is required, scaled floor plans of the entire house along with the associated fee must be submitted. All expenses to upgrade the house to meet the requirements of the Ontario Building Code or Ontario Fire Code would be the responsibility of the property owner.
