Does a Window Replacement Need a Permit?

Permits are not always required for window replacement projects. So when do you need one to replace your windows? In this post, Renewal by Andersen® of Montana shares more information on window replacement permits and tips on obtaining one for your project. 

Do I Need a Permit to Replace My Windows?

Whether or not you need a permit is determined by your location and the scope of the work. Window replacement can be as simple as fitting an insert into an existing window frame. In this type of window replacement, no structural changes or sash removal is required, so it does not require a permit. However, if your window replacement involves the removal of existing sashes or alterations to the window opening, you will need to obtain a permit before starting your project.

How Do I Apply for a Permit to Replace My Windows?

To apply for a permit, you can go to the local building department in your area and submit the requirements. Typically, you will need to outline the tasks that you will be doing and prepare a floor plan that shows the placement of your windows. The rooms must also be identified on the floor plan, and each window must have its dimensions specified. When indicating the size of the windows, the width is always listed first, followed by the height. When structural changes are needed — such as increasing or diminishing an opening — you will be expected to provide the specifics on how you intend to complete this work.

How Long Will It Take for My Permit to Be Issued?

Permit applications for window replacements are reviewed and approved by building inspectors. In some cases, you can get your permit on the same day you apply if an inspector is available. If an inspector is not available, your application may take several days.
