What this means for 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.

A citywide rule is not a parcel answer
Citywide context can't settle one lot's flood zone, historic designation, stream buffer, permit needs, soil conditions, or hidden construction. Confirm those specifics with the appropriate authority and the selected provider before work begins.
