Montana land with no county zoning: what you can build outside city limits
Much of rural Montana has no county zoning. Cities such as Bozeman, Missoula and Kalispell zone every lot. Check with the county planning office whether a lot sits in a zoned area. The first question for any lot is whether it is inside city limits: type the address and ParcelSheet names the town.
Free, no account. ParcelSheet shows the town the lot sits in, its mapped size, parcel lines and FEMA flood zone.
The rules that still apply outside city limits
- Planning help. The Montana Department of Commerce helps counties and towns with planning and lists who to ask. Source: Montana planning help.
- Subdivision review. Splitting land usually needs county review under the Montana Subdivision and Platting Act. Source: Subdivision review; what it allows on a lot.
- Water rights. Wells and surface water use are tied to water rights recorded with DNRC. Source: Water rights; what it allows on a lot.
Deed restrictions and covenants still bind a lot where there is no zoning; they are in the county clerk and recorder's records.
Montana laws that apply inside cities
Once a lot is inside city limits, the city zones it and these state laws limit what the city may require.
- 2023 housing laws. Cities over 5,000 people must allow an accessory dwelling on lots with a home, and duplexes where homes are allowed. Source: 2023 housing laws; what it allows on a lot.
Mapped areas are approximate. This is a plain reading of public law with its sources, not legal advice; the city, county and state offices decide.
