Does an ADU Require Parking? ADU Parking Requirements and Canadian Regulations Explained

Overview of ADU Parking Requirement and Canadian ADU Regulations

Accessory Dwelling Units (ADUs) are gaining popularity across Canada. These self-contained residential units—ranging from basement apartments to converted garages—share many similarities with a main home. A common question is: Does an ADU require parking? Understanding parking requirements is crucial as regulations differ from one municipality to another.

Parking requirements often present challenges for homeowners planning an ADU, particularly in areas where on-street and off-street parking is limited. Rules are formulated by a mix of national, provincial, and municipal bodies. For additional insights, refer to
Building Brantford’s ADU guide,
Woolwich ADU guidelines, and
Burlington’s consolidated application guide.

Municipal Permit Parking: The Impact on ADU Parking Requirement

Municipal permit parking systems balance the availability of on-street parking. In many Canadian cities, local governments issue permits that allow residents to park in high-demand areas.

What is Municipal Permit Parking?

• Permit Zones: Parking permits are tied to residency, regulating access to on-street parking.
• Control Measures: Properties may have a cap on the number of permits issued, managing overall parking supply.
• Objective: These measures aim to ensure fair parking distribution and minimize conflicts in dense neighborhoods.

In some jurisdictions, an ADU’s approval hinges on the availability of legal off-street parking. For example, Toronto often requires additional permits for street parking when building ADUs, while cities like Vancouver have adjusted requirements near transit hubs. More details can be found in
this discussion on ADU principles and through
ADU Start’s permit guide for Canadian cities.

Detailed Accessory Dwelling Unit Parking Requirements

ADU parking rules serve as a foundation for the development possibilities on your property. Common guidelines include the allocation of an additional off-street parking space per ADU, separate from the main dwelling’s requirements.

Typical ADU Parking Rules

• Standard Rule: One extra off-street parking space per ADU is usually mandated.
• Designated Spots: Parking spaces must often be fully paved and situated outside landscape or yard setback areas.

Municipal Examples

• Brantford: One parking space per dwelling unit is required.
• Burlington: For a property with an ADU, a total of three parking spots—two for the main house and one for the ADU—are mandated.
• Township of Woolwich: One off-street parking space per ADU is required regardless of the unit type.

For converted garages and basement suites, parking rules may differ slightly. A converted garage, for example, might require the replacement of an existing parking space. More about garage conversions can be read at
ADU Start’s garage conversion guide.

Urban areas might offer reductions in requirements if close to transit, while suburban or rural zones often insist on additional off-street parking due to limited public transportation.
