Revise municipal zoning laws related to parking requirements

This bill revises Montana's municipal zoning laws to limit mandatory parking requirements for new developments. It directly affects cities and towns that currently enforce minimum parking rules, as well as developers building new residential and commercial properties. The key provisions cap parking requirements at one space per residential unit and one space per 5,000 square feet of commercial space, with additional exemptions for small businesses, affordable housing, and certain facility types. Municipalities that choose to require more parking than these limits must compensate developers for the real cost of constructing the extra spaces. The bill also mandates duplex housing in cities with over 5,000 residents and allows shared parking agreements as an alternative to on-site parking.
