Revise land use laws related to manufactured and factory built homes

This bill revises Montana's land use laws to require that manufactured and factory-built homes be treated the same as other residential properties in zoning regulations. It directly affects local governments, homeowners, and housing developers by mandating equal treatment in zoning districts and establishing a rebuttable presumption that placing these homes will not negatively impact property values. The legislation also updates definitions to include mobile homes and house trailers under manufactured housing, allows manufactured housing as a commercial purpose on state trust land leases, and defines tiny dwelling units as 350 to 750 square feet on permanent foundations. Additionally, the bill clarifies that local design review standards must be clear, objective, and necessary to protect public health or safety.
