What is a Subdivision? Zoning Definition

A subdivision is the process of dividing a larger tract of land into smaller lots that can be individually sold, developed, or built upon. Subdivision regulations are separate from but closely related to zoning ordinances. While zoning controls what can be built on a lot, subdivision regulations control how lots are created, ensuring they have proper access, utilities, drainage, and meet minimum size requirements.

The subdivision process generally requires the property owner to submit a plat, which is a detailed map showing the proposed lot boundaries, streets, easements, and public improvements. Most jurisdictions distinguish between minor subdivisions, which involve a small number of lots and may follow a simplified review process, and major subdivisions, which require full engineering review, public hearings, and approval by the planning commission.

Subdivision regulations typically address road standards, stormwater management, utility connections, sidewalks, open space dedications, and lot design. For example, a community might require that every new lot have a minimum width of 60 feet and frontage on a public street. The developer may also be required to construct roads, install water and sewer lines, and dedicate land for parks or schools as a condition of approval.

Once a subdivision plat is approved and recorded with the county, the new lots become legally recognized parcels that can be conveyed and developed. If you are considering subdividing land, consult your local planning department early in the process, as the requirements vary significantly from one jurisdiction to another and can have a major impact on the feasibility and cost of your project.
