This bill revises county zoning laws in Montana to facilitate the creation of accessory dwelling units (ADUs) on properties with single-family homes. It mandates that counties allow at least one ADU by right on such properties, which can be attached, detached, or internal to the main dwelling. The bill prohibits counties from imposing certain restrictions, such as requiring additional parking, matching the exterior design of the main dwelling, or enforcing occupancy by the owner. Additionally, it allows counties to charge a one-time application fee of up to $250 for reviewing ADU applications and ensures that existing building codes and safety regulations remain applicable.

The bill also amends Section 76-4-130 of the Montana Code Annotated to provide for a 15-day expedited review process for adding an ADU to parcels with existing public water and wastewater services. It includes a termination date of September 30, 2029, for specific provisions related to the expedited review and ADU regulations. Overall, the legislation aims to streamline the process for homeowners to create ADUs while limiting the regulatory burdens imposed by counties.
