Permit for driveway alteration
The information contained in this page is simplified and for information purposes only. In case of a contradiction between the by-law and this document, the former will prevail.
A permit is required to alter or enlarge a driveway.
The maximum allowable width of a driveway is 6.4m (21′).
In the case of irregularly shaped lots (trapeze-like), the maximum width of the driveway between the city sidewalk and the property line is 4.27m (14′).
The paved area for detached dwellings with no garage or a garage at grade (flat) must be at least 0.6m (2′) from the side or rear (in the case of corner lots) property line.
If the garage is below grade (sloped) the paved area must be at least 0.91m (3′) from the side or rear (in the case of corner lots) property line.
In the case of semi-detached dwellings driveways are required to be at least 0.91m (3′) apart (0.455m on either side of the property line).
No tree may be felled in the expansion of a driveway unless it is done in accordance with the by-law concerning the protection of trees (please see Trees guide for more information).
No tree on city property may be removed in the process of driveway expansion unless otherwise authorized by City Council.
No driveway curb or retaining wall is permitted to be less than 0.6m (2′) from a city sidewalk or curb.
Any driveway contiguous (parallel) with a private walkway must be separated by a strip of grass or permanent structure such as a flower box of at least 0.76m (2’6″) in width for 80% of the driveway length.
For all driveway enlargements, the city sidewalk needs to also be modified accordingly. Cost of this modification must be paid by the applicant. A non-refundable deposit is required to be submitted when the permit is issued to cover the cost of altering the access ramp (sidewalk). The deposit depends on how much sidewalk needs to be altered, but normally costs between $1,500 and $3,000 over and above standard permit fees.
Protect your renovation investment by hiring a contractor licensed by the Régie du bâtiment du Québec (RBQ).
