Subdividing refers to the overall legal and regulatory process of dividing a larger parcel of land into two or more smaller lots, typically for the purpose of individual sale or development. This process involves compliance with local subdivision regulations covering lot size minimums, road frontage requirements, infrastructure standards, and stormwater management, among other requirements specific to the jurisdiction.
Platting is the specific step within that process where a licensed surveyor prepares a formal plat — a detailed map showing the boundaries, dimensions, and legal descriptions of each newly created lot, along with easements, right-of-way, and other relevant details. Once approved by the local planning authority and recorded with the county register of deeds, the plat becomes the official legal document establishing the new lot boundaries.
The relationship between the two is sequential: subdividing is the broader process, and platting is the specific technical and legal documentation step within it. A subdivision typically goes through a preliminary plat (showing the proposed layout for review and approval) before a final plat (reflecting the as-built or fully approved layout, recorded once required improvements are complete or bonded).
For a landowner considering dividing property, understanding this distinction matters because each step has its own requirements and potential points of delay. A preliminary plat can be approved, but the final, recorded plat — the document that actually creates legally separate, sellable lots — isn’t complete until required infrastructure (roads, utilities, stormwater systems, as applicable) is either built or financially guaranteed through a bond, which is often the longest phase of the entire subdivision process.
