Housing

SB 504 proposes creating a $75 million grant program to fund permanent supportive housing projects in Montana. The bill would provide grants to nonprofit organizations for constructing, rehabilitating, or acquiring housing that offers long-term affordable leases (for residents earning 60% or less of the area median income) and onsite support services like mental health care, job assistance, and addiction recovery. It allocates $50 million from the general fund and $25 million from a behavioral health fund, with grants disbursed based on project proposals and adherence to specific conditions, including outcome tracking. The program, administered by the Montana Department of Commerce, aims to directly support homeless or at-risk individuals through housing and integrated services, effective July 1, 2025. (Note: The bill died in process in May 2025 and did not become law.)

HB 931 clarifies that developing single-family or multifamily residential housing can be considered a commercial purpose for leasing state trust land. The bill specifically allows nonprofit corporations to lease state trust land to develop "attainable workforce housing." It revises the definition of "commercial purpose" within state law to include such residential developments under a master lease. This change aims to enable the creation of housing for workers on state-owned land.

SB 337 creates a temporary property tax exemption for land undergoing residential subdivision development. Developers can qualify by applying to the department and prepaying five times the most recent annual property taxes and assessments for the property. This exemption applies to the real property within the subdivision for up to five years, or until a habitable dwelling is built on an individual lot, or until 95% of the lots in the subdivision contain habitable dwellings. The bill's provisions apply to property tax years beginning after December 31, 2025.

SB 133 revises the laws governing impact fees that local governments charge on new development. The bill removes the ability for governmental entities to include an administrative fee within impact charges and limits impact fee increases to the rate of inflation. It also updates definitions related to these fees and details the required documentation for their calculation, such as a service area report.

SB 213 revises the state building code to permit certain residential buildings to be constructed with a single stairwell. This change applies to buildings classified as Group R-2 occupancy, which typically includes apartments or condominiums. To qualify for a single stairwell, these buildings must meet specific safety conditions. These conditions include having no more than six stories, a maximum of four dwelling units per floor, an automatic sprinkler system, and at least one window or emergency exit provision for each unit.
