Multi-generational living has long been the norm in many cultures worldwide; however, the lifestyle has seen a surge in popularity as of late particularlyin Ontario due to the housing affordability and supply concerns in the region and the ever-growing laneway and garden suite trend. Contrary to the typical single-family model, multi-generational living fosters a strong sense of support and shared responsibilities while providing an answer to challenges like child care and aging-in-place. 

Transforming existing spaces like coach houses, garages, pool houses or large storage areas into fully functional dwellings, otherwise known as additional dwelling units (ADUs), provides family members, like grandparents or grown children, with their own space, but under their own roof. As seen in recent years, specifically for the Greater Toronto Area, laneway suites offer a unique housing solution when considering home prices in the region and breathe new life into potentially unused areas.  

There are 1,200 back lanes in Toronto between Etobicoke and Scarborough, approximately 26,000 lots with access to a laneway and 350,000 garden lots (a high portion of which could accommodate a garden suite) in the city. ADUs are small homes, generally 1,500 square feet and under, that share the same lot as a detached or semi-detached main house.  

However, the construction of these laneway suites, which are secondary dwellings built on residential lots that abut publicly designated laneways, can offer a more affordable housing option that are already in close proximity to existing amenities.  

It is important that ADUs adhere to the municipality’s by-laws and regulations. Comprehension of the complexities of the by-laws related to secondary suites is the key to ensuring an effortless and comfortable living experience. For example, in Toronto, laneway and garden suites usually do not require committee of adjustment approval (unless variances are required), they are exempt from development charges and do not require vehicle parking. They also do not count towards lot density so improvements to the principal dwelling are also permitted.  

When developing these types of homes, it is important to make sure that they meet the needs of their residents; that they are increasingly functional, yet appealing. Plus, laneway suites can be surprisingly spacious (if designed correctly), as the maximum height allowed ranges from four to six metres and basements are allowed. When designing ADUs where space is at a premium, dual functionality is a must. For example, a peninsula acts as countertop space, but also sit-down dining; a skylight offers natural light, but provides additional headroom above a kitchen sink, too. A significant amount of time should be spent on the design-side of the construction process to make sure an ADU provides the highest-level quality of life.  

From a financial perspective, ADUs could be a good investment. A homeowner could choose to retrofit an existing building on their property, move into the new ADU and rent out the larger principle home. Not only would the home earn rental income, but the overall property would increase in value as well. 

Thoughtful and proactive decisions made at the onset of the renovation process will lead to a successful and prosperous multi-generational living arrangement.
