Subdivision Law and Legal Definition

A subdivision is the development and division of a lot, tract, or parcel of land into two or more lots, plats, sites, or otherwise for the purpose of establishing or creating a subdivision through sale, lease, or building development. Development includes, but is not limited to, the design work of lot layout, the construction of drainage structures, the construction of buildings or public use areas, the planning and construction of public streets and public roads, and the placement of public utilities.

The county commission or like governing body of counties in most states are authorized to regulate the minimum size of lots, the planning and construction of all public streets, public roads, and drainage structures and require proper placement of public utilities to be located in proposed subdivisions of land or in proposed additions to subdivisions of land. The placement of public utilities must conform to the requirements of the applicable building code, state and federal laws, and regulations of state and federal regulatory agencies.

The county commission may may also establish a board of developers to make suggestions to the commission regarding the development and division of subdivisions. The board may advise the commission on the contents of the regulations, revisions that need to be made to the regulations, and assist in resolving disputes between the commission and developers.
