New 1 & 2 Family Dwellings

As daunting tasks go, building a new 1 or 2 family home is certainly up there on the list. Permitting is the 1st official step and can be one of the more confusing ones. The City of Sun Prairie would like to try and make this portion of the process a little less stressful. Below and right (HELPFUL DOWNLOADS) are detailed, step by step breakdown of the items needed to permit the dwelling right through to all of the inspections needed to verify that the structure is safe and up to city and state codes.

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 DSPS (Wisconsin Department of Safety and Professional Services) 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:
