Housing

HB 924 creates the Montana Growth and Opportunity Trust, funded by half of the state's unpredictable revenue (like capital gains or oil royalties) starting in 2027. Interest income from the trust is split: half distributes $15 million annually to five specific programs (disaster resiliency, property tax relief, water development, bridge repairs, and early childhood care), while the other half reinvests in pension funds and housing infrastructure. The bill establishes new accounts for these programs and sets rules for calculating volatile revenue using historical data to stabilize budgeting. It directly affects state budgeting, early childhood services, infrastructure projects, and pension systems through mandatory funding allocations.

SB 266 requires Montana cities with populations over 5,000 to allow triplexes (three-unit homes) and fourplexes (four-unit homes) in areas where single-family homes are permitted, without imposing stricter rules than those for single-family properties. The bill mandates that zoning regulations for these multi-unit housing types cannot be more restrictive than those for single-family residences, including limits on parking (max one space per unit) and reduced requirements for lot sizes or building setbacks. It also encourages local governments to adopt additional housing strategies, such as eliminating or reducing off-street parking mandates and permitting accessory dwelling units. This bill directly affects cities meeting the population threshold, aiming to increase housing density options for residents.

SB 146, the "Private Property Protection Act," would have limited Montana government actions restricting private property use to only those demonstrably necessary for public health or safety. It would allow property owners to challenge restrictions (like zoning rules or fees) in court if they fail to meet strict standards, requiring governments to prove the restriction is the least restrictive option for a compelling public interest. The bill directly affects private property owners and local/state governments by creating a legal process for contesting regulations. However, it died in the legislative process in May 2025 and never became law.

HJ 30 is a joint resolution requesting an interim study on methods to increase housing density and affordability across Montana. The study will be conducted by an appropriate interim committee or staff designated by the Legislative Council. It will investigate incentives for local governments to increase housing density, review state programs supporting housing, and analyze the economic implications of increased density, including property taxes. The study will also identify programs to fund water and wastewater systems for local governments, with final results reported to the 70th Legislature by September 15, 2026.
