Prohibits regulation of a mobile home, a manufactured home, or an industrialized residential structure on private property (other than within a mobile home community) based on age. Allows the owner of a legal, nonconforming residential structure on private property that is damaged or destroyed to replace or repair the structure without losing legal nonconforming use status as long as the structure continues to be used for residential purposes. Provides that a comprehensive plan and ordinance in a county (other than Marion County) may not preclude the installation of manufactured homes that exceed a certain width (in addition to a certain square footage) as permanent residences on a lot on which any other type of dwelling unit may be placed. Provides that after June 30, 2023, a mobile home, a manufactured home, or an industrialized residential structure is not considered a new home or model home subject to the provisions concerning home warranties. Prohibits a county, city, or town from exercising its planning and zoning authority in a way that differentiates between fraternity and sorority houses on the sole basis of whether the fraternity or sorority is officially approved or recognized by the college or university.
