Amend zoning regulations to allow taller buildings

This bill amends Montana zoning laws to allow taller buildings and more flexible housing options in certain municipalities. It requires cities with over 5,000 residents to permit multiple-unit dwellings and mixed-use developments in commercial zones with municipal water and sewer access. The legislation also limits local governments from imposing more than one off-street parking space per unit, restricting parking requirements to those needed for accessibility, and preventing height restrictions on buildings from being fewer than six stories in qualifying urban areas. Additionally, the bill defines key terms like duplex housing and mixed-use developments to clarify what types of structures can be built under these new rules.
