What is a Subdivision?

MCA 76-3-103 defines a subdivision as the division of a piece of land into two or more lots. The regulations are set forth in the City of Helena SUBDIVISION ORDINANCE, Title 12 of Helena City Code.

The purpose of this title is to establish a subdivision review process that is designed to achieve the objectives of the Montana Subdivision and Platting Act, Title 76, Chapter 3, Montana Code Annotated (MCA). The process of dividing land into parcels is a necessary and important function in the growth of a community. When, where, and how development occurs establishes land division patterns for the community that will last for generations. The subdivision review process allows the community to take a close look at proposed developments before final action by the governing body. The City of Helena 2001 Growth Policy provides guidance for subdivision reviews. (Title 12-1-2)
