Preserving the diverse character of our neighbourhoods and promoting access to adequate housing for everyone is the objective of the city’s By-law for a Diverse Metropolis which came into force on April 1, 2021.
From now on, anyone who is developing a residential project with an area greater than greater than 450 m2 (equivalent to approximately five dwellings) must sign an agreement with the city to contribute to its supply of social, affordable and family housing.
The by-law applies to your project if it is adding at least 1 dwelling unit and the total residential area of the building is more than 450 m². The project can be a new building, an expansion or a conversion
The developer’s contribution depends on the scope and location of the project. It can take a number of forms, including:
- Transferring land or a building in exchange for a financial contribution
- Building homes that meet certain criteria
- A financial contribution
What to do
The first step is to complete the project form and submit it at the permit counter of the borough where the project is being built. The borough’s permits team will let you know about the next steps.
To complete the project form, you must understand certain concepts in the by-law. See section 1 of the by-law, pages 1 to 3.
If you have questions, contact the borough’s permits team.
Off-site family housing
Under certain conditions, you can fulfill your family housing commitments on another site. If you would like this option, you must provide written permission from the site owner. Consent form (in french)
Definitions: Types of housing
For the purposes of the by-law, a social housing unit is a home whose construction costs are subsidized by the city or the government of Québec.
Social and community housing is developed by cooperatives, non-profit organizations and the Office municipal d’habitation de Montréal.
Affordable housing, which is different from social housing, targets a diverse array of households whose needs aren’t met by the private market. To provide households with these homes, the by-law combines a discount on the market value offered by the developer with various housing subsidy programs that will maintain its long-term affordability.
For the purposes of the by-law, a family housing unit is a home with at least five rooms, including three bedrooms and a residential area that provides sufficient living space for a family.
A family home can be social, affordable or market price.
Please note that appendix B of the by-law is regularly updated when new affordable housing zones are adopted.
