Local Building Codes and Permit Requirements in Green Bay

Permit Guidelines

In the City of Green Bay, most projects that affect the exterior also require a building permit from the Department of Community Development. Important notes: Roofing: Permit is required for major repairs or complete roof replacement in case it involves any kind of alteration of the existing structure or a switch in the roofing material.

  • Siding and Gutters: Permit needed when style changes or structural design changes are made to the siding, while installation of the gutters or downspouts is normally exempt unless included in larger renovations.
  • Windows and Doors: Replacement of windows or doors of the same style is permit-exempt; however, should the opening be changed or the style of window changed, a permit would be required.
