Secondary Dwelling Units

Secondary Dwelling Requirements

Check with your municipality to ensure that your property is zoned for a secondary dwelling unit. Each municipality has different zoning requirements, and some may not permit secondary dwelling units at all.

Your secondary dwelling unit must comply with the Ontario Building Code, which sets out standards for construction, fire safety, plumbing, electrical systems, and other aspects of the building.

You will need to obtain the necessary permits from your municipality before constructing or renovating your secondary dwelling unit. These permits may include a building permit, plumbing permit, and electrical permit.

The secondary dwelling unit must be separate from the primary residence with its own entrance, kitchen, bathroom, and sleeping area. The unit must be self-contained and not share any common areas with the primary residence.

The size of your secondary dwelling unit is typically limited to a maximum of 40% of the total floor area of the primary residence.

You must provide at least one parking space for the secondary dwelling unit.

Navigating the permitting process can be daunting. We’ll handle all the paperwork, ensuring a smooth and hassle-free approval process.

Finished Basement vs Legal Secondary Dwelling Unit

A finished basement typically serves as additional living space within the main residence and is often used for recreational purposes. It may not have separate utilities or comply with specific regulations for independent dwelling units. On the other hand, a legal secondary dwelling is an independent living space with its own amenities, complying with local building codes and zoning regulations. It requires specific permits, has separate utilities, and adheres to safety standards, making it suitable for independent occupancy or rental. It’s crucial to understand and comply with local regulations to distinguish between a finished basement and a legal secondary dwelling.

Coach Houses & Accessory Dwelling Units, Laneway Apartments

A coach house, also known as a carriage house or a secondary suite, is a detached, standalone residential structure typically located on the same property as a primary residence. Historically, coach houses were used to store horse-drawn carriages and house staff. In contemporary usage, these structures are often repurposed or newly constructed as independent living units.

Laneway apartments, also known as laneway houses, are small, standalone dwellings located in the rear yards or laneways of existing residential properties. Similar to coach houses, they provide additional housing options within urban areas where space is limited.

Both coach houses and laneway apartments represent innovative approaches to housing, allowing property owners to maximize the use of their land and address the growing demand for diverse and flexible housing options. Regulations for these structures vary widely, and compliance with local laws is crucial for their legal construction and use.

Detached garage

A detached garage is a standalone structure on a property that is designed and constructed to provide covered parking for vehicles, storage, or additional functional space. Unlike an attached garage, which is connected to the main dwelling, a detached garage is a separate building located either near the main residence or elsewhere on the property.

Detached garages are common in residential areas, especially in suburban and rural settings, where larger lots allow for the placement of separate structures. They offer homeowners additional space for parking and storage while maintaining a certain degree of flexibility in how the space is utilized.
