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 223 amends an existing law to ensure that any interest or income earned from a $12 million fund for workforce housing is retained within that fund. This fund is specifically allocated to assist employees working at state facilities that house state inmates or behavioral health patients, particularly in eligible rural counties. By retaining the earned interest, the bill aims to increase the total resources available for initiatives such as buying down construction costs, providing loans, or acquiring housing for these employees. The bill takes effect immediately and applies retroactively to interest earned on or after June 14, 2023.
SB 252 revises land use laws concerning manufactured and factory-built housing. The bill requires municipal and county zoning regulations to treat these housing types the same as other residential units, preventing differential treatment. It also establishes a rebuttable presumption that placing manufactured or factory-built homes in residential zones will not adversely affect conventional property values. Additionally, the bill includes manufactured housing as an allowable commercial purpose in state trust land leases and provides relevant definitions.
SB 405 proposed transferring $50 million from Montana's general fund to the Housing Montana Fund within 15 days of enactment, directly supporting state housing programs and affordable housing initiatives. It required the Department of Commerce to update administrative rules related to housing by the start of the 70th legislative session. The bill would have taken effect July 1, 2025, but died in committee on May 23, 2025, after being tabled in April 2025. This was a substantive funding bill, not a procedural measure, with no further legislative action taken.
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 532 revises county zoning laws to require counties with zoning regulations to allow accessory dwelling units (ADUs) on lots with existing single-family homes. It mandates that counties permit at least one ADU "by right," meaning without requiring special permits or public hearings, and sets size limits for detached or attached units. The bill prohibits counties from imposing certain restrictions on ADUs, such as requiring additional parking, owner occupancy, or specific exterior designs. Counties may charge a one-time application fee for reviewing ADU applications and must comply with expedited sanitation review provisions.
