Homeowners and homebuyers


A secondary suite can enable homeowners to generate additional, legitimate income. It may also assist prospective homebuyers to qualify for a mortgage when their regular incomes would otherwise limit them to renting. A secondary suite can also allow homeowners to accommodate friends and family members, such as elderly parents or dependant children, within their homes, while preserving independence and privacy. It can provide older homeowners with the security of having others nearby in case of an emergency or to help with household maintenance (e.g. windows, painting).




Secondary suites are a form of housing that is generally considered affordable due to their size and location. An increase in the number of safe legal secondary suites provides more housing choice in price and location for prospective tenants. A well designed suite and rental agreement also protects and strengthens tenant rights.


The community


The supply of affordable housing in Calgary has not kept pace with demand, as housing costs have risen much faster than incomes. There is a need for more affordable market rentals. In Calgary, an estimated 38,610 households face a housing affordability challenge. They are earning less than $44,000 and spending greater than 30% on housing costs and cannot afford average market rents in Calgary.

 An increase in the number of safe legal secondary suites in the city creates naturally affordable housing options at the lower end of the market. The increased number will also contribute to the creation of complete communities that have a wide range and flexible choice of housing types.
Secondary suites also provide an opportunity for modest density increases in low-density neighbourhoods (also called invisible density and “contributing softly”), while respecting the scale and character of existing neighbourhoods and supporting the viability of existing
community facilities, schools, transit, etc.
