What parking requirements apply to a Toronto home with a registered basement apartment?

Toronto's parking requirements for homes with registered basement apartments have been significantly relaxed in recent years, and in many cases a secondary suite does not require any additional parking beyond what already exists for the main dwelling. This is welcome news for homeowners in established Toronto neighbourhoods where properties often have limited driveway space or no garage, and where adding parking would be physically impossible.

Under Toronto Zoning By-law 569-2013 and its subsequent amendments supporting secondary suites, the city has moved toward reducing or eliminating additional parking requirements for secondary suites in areas well-served by public transit. In many parts of the city — particularly areas within walking distance of TTC subway stations, streetcar lines, and GO Transit stations — the parking requirement for a secondary suite has been reduced to zero additional spaces. This means if your property already has the required parking for the main dwelling (typically one space), no additional parking is needed for the basement apartment.

In areas further from transit, the specific parking requirements depend on your property's zoning designation and the applicable parking standards. Some zones may still require one parking space per dwelling unit, meaning a home with a secondary suite would need two spaces total. However, the City has introduced provisions allowing reduced parking through minor variance applications at the Committee of Adjustment, and these applications are frequently approved — particularly when the property is near transit, has on-street parking available, or when adding a parking space would require removing significant landscaping or green space.

The practical reality in many Toronto neighbourhoods is that existing driveways already satisfy the parking requirements. A standard single-car driveway that can accommodate one vehicle is sufficient for the main dwelling, and if no additional parking is required for the suite, you are already compliant. If your property has a tandem driveway (two cars end-to-end) or a double-wide driveway, you likely have more than enough parking for both units. Properties with rear laneways and garage access — common in neighbourhoods like the Annex, Trinity Bellwoods, Leslieville, and Bloor West Village — typically have ample parking flexibility.

There are a few important details to be aware of. The parking space must meet the City's minimum dimensions — typically 2.6 metres (8.5 feet) wide and 5.6 metres (18.4 feet) long for a standard space. The space must be on your property (you cannot count on-street parking toward the requirement). If your property currently has a front-yard parking pad, be aware that Toronto has been increasingly restricting front-yard parking in some areas, and converting lawn to parking may require a permit.

If your property cannot meet the parking requirements and a variance is needed, the Committee of Adjustment process costs approximately $2,000 to $4,000 (including application fees and, in most cases, a planning consultant to prepare the application) and takes 6 to 12 weeks from application to decision. Neighbours are notified and can attend the hearing to support or oppose the application. In practice, parking variances for secondary suites in transit-accessible areas are approved at a high rate.

Before starting your basement apartment project, confirm the specific parking requirements for your property address by checking the City of Toronto's zoning bylaw interactive map online or contacting the Building Division directly. Your contractor or an experienced planning consultant can also review this as part of the pre-construction planning phase.
