Outdoor landscaping and installations
The City of Saint-Lambert regulates outdoor landscaping and installations. This page gives you an overview of the main provisions in the by-law.
The totality of a front yard, with the exception of access aisles to the building or to the parking area, must be dealt with as a treated area.
No hedge, fence, berm, or other form of landscaping may be installed on the first 60 cm (24 in.) of the property adjacent to the sidewalk or the curb. That section of land must remain level with the sidewalk or the curb.
No landscaping or filling work that raises the level of the land more than 60 cm (24 in.) above the level of the centre of the street may be carried out.
The following are prohibited within the visibility triangle:
- Any construction, fence, hedge, berm, or other form of landscaping that exceeds 75 cm (29.5 in.) in height, relative to the street level;
- Any terrace
Définition: The entire area used for parking motor vehicles, including the parking spaces, the manoeuvring areas for entering and exiting the spaces, and the access aisles between the parking spaces, the manoeuvring areas, and the street.
- All circulation aisles and parking areas must be paved;
- The parking area must not take up more than 50% of the area in the front yard or 33% in the case of a row house;
- In the case of a corner lot, the vehicular access (curb cut) must not be located less than 7.5 m (24.7 ft.) from the point at which the street rights-of-way intersect
Number of driveways
- Only one driveway is permitted for a property less than 24 m (78.8 ft.) wide. For wider lots, a maximum of two driveways is permitted. They may be arranged in a semi-circle or adjacent to one another;

- A driveway may not be wider than 6.1 m (20 ft.);
- Where permitted, the combined width of adjacent driveways may not exceed 12 m (39.4 ft.).
Note: The width of a parking space with an adjoining pedestrian walkway is determined by the width of the curb cut. Therefore, a driveway that includes a walkway may not be arranged vis-à-vis the slopes of the curb cut.
If you wish to modify a parking space that would require the alteration of a curb cut, you may submit a request to alter a curb cut. You will be required to pay all applicable fees. No alterations may be made on sidewalks less than 5 years old.
