What a Lorraine house asks of its windows and doors
Lorraine counted 9,502 residents at the 2021 census, on only 6.02 km². That is a density of 1,610 people per km², and almost all of it is detached houses on a slope above the Rivière des Mille Îles.
A town planned as a houses-only suburb
A group of businessmen founded Lorraine in 1960. They wanted single-family homes with no industry, no commercial sprawl and no high-density housing. The city still says new construction must follow strict planning rules that keep the architecture coherent, so a facade change is a matter for the whole street.
Almost every sale is a detached house
Centris reports that 106 of the 110 Lorraine sales in the last four quarters were single-family houses. The median price for those houses was $773,937. At that value a mismatched window shows from the street and costs you at resale, so we match grille style and frame colour to the facade.
Garth House sets the heritage tone
The Maison Garth was built in 1833 and has been a classified heritage monument since 1975. The city bought it in 1962, used it as town hall until 1981 and now holds council meetings there. Homes nearby sit in a town that treats its old stone and mansard roofs with care.
Brick and stone facades stay unpainted
The city bans paint or varnish that could alter the integrity of exterior brick, stone or architectural block. When you swap a door or a window frame, the surrounding masonry is meant to stay as it is. We plan the frame colour to sit well against that finish.
Does Lorraine require a permit to replace windows and doors?
Yes, even for a like-for-like swap. We read the city’s permit page and its aide-mémoire on 13 November 2026. The Service de l’urbanisme et de l’environnement gives the final answer for your address.
A permit comes before any door or window work
The city’s permit page says a permit is required to replace doors or windows. Its aide-mémoire lists “remplacement de portes et fenêtres” under exterior renovation permits. Apply through the city’s online permit page and wait for the permit before work starts.
The CCU reviews changes of colour, style, size or place
If the job changes the colour, the style, the dimensions or the position of a door or window, the file goes to the Comité consultatif d’urbanisme first. It must be approved at a CCU meeting before work begins. The aide-mémoire repeats this in a footnote.
Plan for the monthly CCU calendar
The CCU meets once a month except in December. The city warns that this can add delay. After the CCU recommends a file, the municipal council makes the final decision and the permit follows. Start the file early if your project is a colour or style change.
Who to call
Call the urbanism department at 450 621-8550 or write to urbanisme@lorraine.ca. The city lists its by-laws, including permits (URB-02), zoning (URB-03) and the PIIA by-law (URB-08), on its construction and renovation page. Our written quote lists each opening with its size, so you can show the city exactly what changes.

Questions Lorraine owners ask
Do I need a permit to change my windows in Lorraine?
Yes. The city says a permit is required to replace doors and windows. Ask the urbanism department which documents it wants before you order.
When does the CCU have to approve my windows?
The city sends a file to the CCU when the colour, the style, the dimensions or the position of a door or window changes. The CCU meets monthly except in December, so allow time.
Can I paint the brick around my new door?
No. Lorraine forbids paint or varnish that can alter the integrity of exterior brick, stone or architectural block. We choose a frame colour that works with the masonry as it is.
How long does a Lorraine permit take?
The city gives no fixed number of days. It says the monthly CCU meeting can add delay, and that the council decides after the CCU. Ask the department for a current estimate.
Is there provincial help for new windows in Lorraine?
Québec’s Rénoclimat program pays $300 per window from files opened since 1 October 2026, up to $4,500 for a house. The page was updated on 13 October 2026. We explain the file steps at the estimate.
