Land use: zoning and growth management; required studies and documents for site plan approval; limit. Amends sec. 501 of 2006 PA 110 (MCL 125.3501).

HB 5531 requires local governments in Michigan to make a decision on site plan approvals within 60 days. It limits when officials can request additional studies or documents after initial approval, allowing such requests only for material changes, safety concerns, or to ensure compliance with existing standards - preventing new requirements unrelated to the project. This affects developers seeking land use approvals and local officials reviewing applications. The bill clarifies that extra studies cannot be used to delay projects or revisit issues already approved.
