Land use: zoning and growth management; non-fire rated windows on accessory dwelling units; prohibit local governments from restricting. Amends 2006 PA 110 (MCL 125.3101 - 125.3702) by adding sec. 205c.

Michigan House Bill 6083, introduced on June 16, 2026, aims to prevent local governments from prohibiting the use of non-fire rated windows in accessory dwelling units (ADUs) that are situated more than 12 feet away from other structures. An ADU is defined as a secondary dwelling unit on the same property as a primary residence. A non-fire rated window is one that hasn't been certified to withstand fire exposure for a specific duration. The bill seeks to standardize regulations across municipalities, ensuring that homeowners can install such windows in qualifying ADUs without facing local restrictions.

Supporters of HB6083 argue that the bill promotes housing flexibility and affordability by reducing regulatory barriers for homeowners wishing to add ADUs to their properties. They contend that allowing non-fire rated windows in these units, when safely distanced from other structures, balances safety considerations with the need for increased housing options. Proponents also suggest that the bill could encourage the development of ADUs, providing additional rental income for homeowners and addressing housing shortages in certain areas.

Critics of HB6083 express concerns that the bill may undermine local authority and compromise safety standards. They argue that local governments are best positioned to determine appropriate building codes and safety measures tailored to their communities. Opponents worry that prohibiting municipalities from restricting non-fire rated windows in ADUs could lead to increased fire risks, especially in densely populated areas. Additionally, some believe that the bill may set a precedent for state overreach into local zoning and building regulations.
