Housing: other; automatic fire sprinkler systems for electric vehicle parking spaces; require certain buildings to have. Amends 1972 PA 230 (MCL 125.1501 - 125.1531) by adding sec. 4i.

HB 4850 requires automatic fire sprinkler systems in parking spaces designated for electric vehicles at new multi-family buildings (excluding single-family homes) and mandates retrofitting existing multi-family buildings within 180 days of the law's effective date. The bill applies to buildings constructed after the law takes effect and to existing multi-family structures (excluding single-family or 1-2 family detached dwellings), with installation standards set by the Joint Committee on Administrative Rules. It defines "electric vehicle" as a solely electric vehicle (no gasoline/diesel capability) and specifies sprinkler systems must meet fire protection engineering standards. The law does not apply to single-family homes or small detached residential buildings.
