In Michigan, the permitting and regulatory framework for ADUs is primarily governed by local municipal zoning ordinances, which are increasingly being updated to encourage their development, although specific rules on size, placement, and parking can vary widely. All construction must adhere to the Michigan Building Code, which mandates standards for structural integrity, fire safety, and energy efficiency. The predominant housing stock in cities like Warren, consisting largely of single-family homes and older post-war construction, means that ADU integration often requires meticulous site analysis and design to harmonize with existing architectural styles and infrastructure.
