Housing: landlord and tenants; definition of rental unit; modify. Amends sec. 1 of 1972 PA 348 (MCL 554.601).

This bill amends the Michigan Landlord and Tenant Act to update the official definitions of key terms used in residential rental agreements. It clarifies who qualifies as a landlord, including property owners and authorized agents who manage the premises or collect rent. The legislation also expands the definition of a rental unit to explicitly include mobile home spaces and establishes a broader list of acceptable sources of income for tenants, such as housing vouchers and Social Security benefits. Additionally, it refines the definition of a security deposit to clarify what funds are included and excluded from the category. These changes aim to provide clearer legal standards for interactions between landlords and tenants across various housing types.
