Permitting is highly decentralized; most incorporated cities and some townships operate their own building departments and issue their own permits. The Washtenaw County Building Department serves as the authority having jurisdiction only for those townships and villages that have not established their own building departments. Applicants must verify jurisdiction based on the specific property address before submitting plans.
The Washtenaw County Water Resources Commissioner's Office requires separate soil erosion and sedimentation control (SESC) permits for most earth-disturbing activities.
Cómo encaja con el estado
La autoridad estatal aquí es Michigan Department of Licensing and Regulatory Affairs. El expediente del condado no la reemplaza — añade la oficina de permisos, las reglas locales y el camino real de presentación.
