Senate Bill No. introduced by F. Mandeville and others aims to revise county zoning laws to facilitate the creation of accessory dwelling units (ADUs) in areas where county commissioners have established zoning regulations. The bill mandates that counties allow at least one ADU by right on lots containing single-family dwellings, with specific size limitations. It also prohibits counties from imposing certain restrictions on ADUs, such as requiring additional parking, matching the exterior design of the primary dwelling, or enforcing occupancy by the owner. Additionally, counties may charge a one-time application fee of up to $250 for reviewing ADU applications.

The bill amends Section 76-4-130 of the Montana Code Annotated to include provisions for expedited sanitation reviews for ADUs added to parcels with existing wastewater treatment systems. It also establishes a termination date for certain sections of the bill, set for September 30, 2029. Overall, the legislation aims to streamline the process for creating ADUs while ensuring that counties cannot impose overly restrictive regulations that could hinder their development.
