What Côte-Saint-Luc homes ask of a window
The 2021 census counted 14,605 private homes in Côte-Saint-Luc, 1,115 more than in 2016. Apartments in buildings of five storeys or more are over half of them. The city also has the highest share in the Montréal agglomeration of households led by someone aged 65 or older, at 43.7%.
Towers on Cavendish and Marc Chagall
The city’s 2024 planning programme describes buildings of 9 to 13 storeys on Marc Chagall Avenue and towers of up to 20 storeys on Cavendish Boulevard. In a tower, the condo corporation decides which windows and colours are allowed. Ask your syndicate before you shop, and send us its rules.
The 1950s grid around Westminster and the Village
The oldest part of the city grew in the 1950s with detached houses, semi-detached homes, rowhouses and duplexes, then with 5- to 14-storey buildings between Westminster Avenue and the railway. Some houses from the 1930s and 1940s remain in the south of the city, but many were rebuilt larger. We measure each opening, because a rebuilt house and an original one sit side by side.
Mid-century streets near Kildare and Mackle
Between 1960 and 1975, the area around Kildare Road grew with loops, cul-de-sacs and a mix of duplexes, detached and semi-detached houses and multifamily housing. Windows from that time are at least 45 years old if they are original.
Larger houses in the Musical Streets and by Décarie Square
Single-family houses in the Musical Streets date from 1985 onward. The exclave by Décarie Square was built up from the late 1990s with detached, semi-detached and town houses. Newer and larger houses often have taller or wider openings, so we make each window to the size we measure.
What does Côte-Saint-Luc require for windows and doors?
A permit. Côte-Saint-Luc is a separate city and not a borough of Montréal, so the Montréal permit page does not apply here. The city’s renovation page lists replacing windows as exterior work that needs a permit. No work can begin before the permit is issued.
What counts as exterior work
The city’s list names replacing windows and adding, sealing or changing the size of a window, door or similar opening. The page does not describe a same-size exception, so plan for a permit. The city also says its page is a simplified guide and that the Construction By-law 2593 prevails. Read the city’s renovation page before you order.
A visible façade goes through the SPAIP review
Exterior work on a visible façade falls under the city’s site planning and architectural integration programme (SPAIP). The city publishes architectural design guidelines for low-density homes, and a coordinator can help with your project. The 2026 fee schedule lists a $350 study fee when a project goes to the Planning Advisory Committee.
Documents and fees
You apply online. For openings, the city asks for the technical specifications of the new doors or windows, photos of the existing façades or before-and-after renderings and a detailed quote. A certificate of location may also be required. The 2026 schedule lists a $75 request fee and $10 per $1,000 of work for the permit. An engineer’s plan can be required if an opening changes size.
Book Urban Planning, then follow the steps
You can book an appointment with Urban Planning by phone or by Teams. After you apply, you get a reference number and an agent contacts you if more is needed. You pay once the permit is approved, and the permit must be visible from the street. An inspector visits during the work. The construction procedures page explains the longer approval path for larger projects.

Questions Côte-Saint-Luc owners ask
Must I get a city permit for new windows in Côte-Saint-Luc?
Yes. The city lists replacing windows as exterior work that needs a permit. It does not describe a same-size exception on that page, so book an appointment with Urban Planning before you order.
Do the Montréal borough rules cover my address?
No. Côte-Saint-Luc is a separate city with its own by-laws, its own fee schedule and its own permit process. The Montréal borough pages do not apply to your address.
Does my house on Randall, Hudson or Wolseley need special care?
The city’s 2024 planning programme names Randall Avenue (houses of the 1930s and 1940s) and Hudson and Wolseley avenues as sectors of interesting heritage value. It also says no building has a specific protection status so far. Work on a visible façade still goes through the SPAIP review.
I live in a tower. Who approves my new windows?
Your condo corporation sets the rules for windows, colours and finishes, and the city sets the permit. Read your declaration of co-ownership, then send us both. We prepare the quote and the specifications for the permit file.
Can I get help paying for windows in Côte-Saint-Luc?
Quebec’s Rénoclimat program can pay $300 per window, up to $4,500 for a house and $6,000 for a multi-unit building. Only files opened since October 1, 2026 qualify, and conditions apply. Read the rules on quebec.ca before you sign.
