When you think of the Building Inspection and Code Enforcement Department you probably think permits, right? Issuing permits and performing inspections, while at the center of our department, is definitely not all we do. Our inspectors enforce the State of Wisconsin Building Code Statues and city ordinances. They are involved in projects such as:

  • Additions
  • All electrical changes
  • Decks
  • New construction
  • Pools
  • Remodeling
  • Replacements of HVAC equipment, water heaters and softeners

We are also the enforcement arm of many City of Sun Prairie Ordinances, including long grass and weeds, snow and ice removal, and health and safety concerns. We also issue sign permits, handle property addressing and verify Conditions of Approval for most commercial improvements.

NEW Online Building Permit For New Construction of 1 & 2 Family Dwellings

Effective March 1, 2018 the City of Sun Prairie will be only accepting permits for one and two family new homes after the builder (or owner) has completed the State online permit. The Online Building Permit System was developed by the Wisconsin Department of Safety and Professional Services (DSPS) to allow municipalities to gain compliance with 2015 Act 211. The owner, builder, or agents shall complete the application form and the Online Building Permit System will route it to the enforcing jurisdiction. Permit application data is used for statewide statistics on new one and two family dwellings, as well as the local code administration.

The 1st link below gives a more detailed look at the electronic filing and the 2nd link is the application itself:
