Subdivisions
All subdivisions are reviewed for their compliance with the Lincoln County Subdivision Regulations, which are a requirement of Montana Law under 76-3-501 MCA. Originally adopted by Lincoln County via Resolution No. 23, on January 8, 1975, they underwent their most recent update in May 2026. The regulations are designed to be used in conjunction with the Montana Subdivision and Platting Act, the Montana Sanitation in Subdivisions Act, the Uniform Standards for Final Subdivision Plats, other federal, state, and local laws, and officially adopted local plans and policies. For a quick summary and infographic of the process, see our Citizen’s Guide.
