Plans are reviewed under the Michigan LARA (state mandate) + city/township building department code (IRC Michigan Residential); apply through City of Wayne Building & Engineering before work begins.

Retrofit windows (inserting into existing frames) often do not require a permit, but new construction windows or altering the wall structure almost always requires an inspection.
Code Compliance & Inspections
Because of severe winter weather in Michigan, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Michigan Building Code.
Zoning & Cost Factors
Michigan grants zoning authority to townships, cities, and villages, leading to a highly fragmented regulatory landscape, especially concerning short-term rentals. Fortunately, Michigan maintains relatively builder-friendly regulations, keeping base permit fees competitive.
