Search by lot number

A search by lot number is the most efficient method. Enter one of the lot numbers and the tool will determine the area in which it is located. You must then specify the residential floor area and the number of dwelling units.

Search by area

If you do not know the lot number, perform a search by area using the pull-down menu. Numbered 1 to 5, the areas are used to calculate the amount of a financial contribution. If a project spans two areas, the highest of the two contribution values applies.

Project characteristics

After entering the area or lot number, you must provide the residential floor area and the number of dwellings for your project.

Residential area

The residential area corresponds to the total floor area, including common areas (e.g., mezzanines, stairs, elevators, lobby). Commercial spaces, parking lots and basement areas not occupied by dwellings or parts of dwellings must be excluded.

Excluded areas:

• Floor area of social housing.
• Floor area of affordable housing subject to a resale price control for a minimum period of 20 years.
• Floor area of non-market housing owned by a non-profit organization, a cooperative, a government, a paramunicipal corporation, a public educational institution or university, or a social trust, provided that certain conditions set out in the by-law are met.

View the by-law for further information. If you have any questions, please contact the Service de la stratégie immobilière et de l’habitation at [email protected]

Until December 31, 2026, all office floor area converted to residential dwellings units in Area 1, corresponding roughly to the downtown core, is excluded from the residential floor area calculation.

Number of dwellings

The number of dwellings is used to calculate the family housing contribution.
