Residential Additions

Before You Apply

It is important to contact the Zoning Department while planning your project to confirm setback requirements in your zoning district.

If you have a private sewage system, you must also contact Waukesha County for a Preliminary Site Evaluation (PSE) before you can receive a building permit from the village.

Please feel free to contact us with any questions you may have regarding your project.
