If your property is inside Ontonagon city limits, your permit application goes to Ontonagon Building Department, not the Ontonagon 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 Ontonagon 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.
