If your property is inside Ann Arbor city limits, your permit application goes to Ann Arbor Building Department, not the Washtenaw County Building Department. Properties just outside city limits typically fall under county or township jurisdiction. If you're not sure which applies to your parcel, check with your local assessor's office or look up your property on Washtenaw County's GIS map. We include a full engineered plan set with every kit that meets what both city and county departments typically ask for — so either way, you're covered.
