Construction of New Commercial Building

New commercial building construction and additions to existing buildings require a building permit before construction begins. All plans submitted to our department we require an additional digital copy.

Erosion Control
Erosion Control permits for Commercial Buildings are usually required. Please call Gabe Szecsy at 262-524-3579 for more information.

State Approved Plans
You may need to have State Approved Plans if:
  • This is a new building or structure containing more than 5,000 square feet of total floor area.
  • This is an addition to a building or structure where the area of the addition results in the entire building or structure to exceed 5,000 square feet of total floor area.
  • This is an alteration of a space involving more than 10,000 square feet of total floor area.
Volume Measurement
The use of 50,000 and 100,000 cubic feet of total volume in lieu of 5,000 and 10,000 square feet of total floor area may be used provided calculations are included which will show the total volume.
