What matters for project planning
Sterling Heights requires a mechanical permit for HVAC replacement, processed through the city's Office of Building, located at 40555 Utica Road. The city separately enforces its own floodplain permit requirements -- reviewed alongside Michigan Department of Environment, Great Lakes, and Energy requirements -- for work proposed within mapped flood hazard areas.

Verify the property, not just the city
Citywide context cannot establish a parcel's flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
