Sterling Heights room addition permit rules — the basics
Room addition building permits in Sterling Heights must be submitted in-person or by mail to 40555 Utica Road, Sterling Heights, MI 48313 (not online). Phone: (586) 446-2360. Email: bldg@sterlingheights.gov. Schedule a pre-application appointment at (586) 446-2404. Trade permits (plumbing, electrical) can be applied for online simultaneously. Michigan LARA-licensed contractors are required for each trade (verify at lara.michigan.gov).
Call 811 (MISS DIG) at least 3 business days before foundation excavation. DTE Energy gas and electric lines, Sterling Heights DPS water/sewer, and other utilities must be located. Michigan Public Act 174 requires MISS DIG notification before any excavation; failure to call creates significant liability.
Michigan's energy code for Climate Zone 5A governs all new conditioned space in the addition: ceiling R-49 minimum, walls R-20+R-5 continuous (or R-13+R-10 continuous), floor R-30, windows U-0.30 maximum and SHGC 0.40 maximum. These are among the highest insulation requirements of any city in this guide, reflecting Sterling Heights' 6,500+ annual heating degree days.
Foundation footings must extend 42 inches below grade (Michigan's frost depth standard) to prevent frost heaving. The footing inspection before concrete pour is the critical checkpoint verifying frost-line depth.
