West Allis window permitting office

Does the City of West Allis require a building permit for replacement windows?

West Allis does not require a building permit for replacement windows as long as they are the same size as the existing windows. Per the “Do I need a Building Permit?” informational bulletin on the City of West Allis website:

"A building permit is not required to replace windows or doors to a dwelling or garage with the same size window or door. A permit is required to increase the size of an opening for a larger window or door due to structural considerations. A permit is required to decrease the size of a window or door because of code requirements relating to egress and light and ventilation in habitable rooms.”For questions and correspondence:
