Install or Replace a Window

Sections de la page

Who can install or replace windows?

Homeowners and contractors can apply for the Short-form or Long-form Permit.
Homeowners and contractors can install or replace windows if the work is being done on a 1-2 unit owner-occupied home.
You must hire a contractor to perform the work if it’s being done on a three-family or bigger dwelling, such as:
- an apartment building
- a multi-unit condo, or
- one floor of a triple-decker house.

What permits do I need?

Short-Form Permit

For replacing a window that already exists and no other structural changes need to be made, such as expanding the window size.

OR

Long-Form Permit

For creating a new window where one did not exist, or when any structural changes need to be made, such as opening a wall or expanding the window size.
