Revise zoning laws related to the rental of a primary residence

This bill prevents local governments in Montana from banning short-term rentals of a property owner's primary residence, including accessory dwelling units or homes on neighboring lots that share a boundary. It defines a primary residence as a home where the owner lives at least 183 days per year and applies to all county and municipal zoning regulations. The law also amends existing state statutes to limit local zoning authority, ensuring communities cannot impose fees or restrictions that would prevent these specific rental arrangements. Property owners who meet the occupancy requirement can now rent out their homes or nearby properties without local prohibition, regardless of how their jurisdiction is divided into zoning districts.
