New rules on Accessory Dwelling Units and other uses (ADUs) – City of Bozeman


On September 25, 2020 the City of Bozeman adopted changes to the municipal zoning code in Supplement number 10 Update 2.

In this update, the city made it allowable for zoning districts R-S and R-1 to have detached Accessory Dwelling Units (ADUs) permitted by code. A detached ADU in these zoning districts does require that the principal structure be owner occupied. And either the ADU or the principal structure may be rented, but not both at the same time. This is a huge adjustment and comes as welcome news to alleviate confusion and create more equitable opportunities between the individual residential zoning areas.

According to the municipal code page (direct link HERE>> ) accessory dwelling units that are detached are now allowed in R-S, R-1, R-2, R-3, R-4 and R-5 residential zoning districts. They can be above accessory buildings or on the ground floor with alley access. They cannot exceed 600 sq ft of living area or 22’ in height or have more than 1 bedroom. Occupancy is not meant to be for more than 2 people.

There were additionally some use clarifications and broadening for the commercial uses including making it more clear on what is required to have a main level office on Main Street between Grand and Rouse.
