What Is a Plat Map?
A plat map (also called a plat or subdivision plat) is a detailed drawing prepared by a licensed surveyor that shows how a larger parcel of land has been divided into individual lots, blocks, and streets. When a developer creates a new subdivision, they record a plat map with the county clerk. This plat becomes the official reference for all legal descriptions within the subdivision.
Instead of using metes and bounds or government survey descriptions, properties in platted subdivisions are described by lot and block number (for example, "Lot 12, Block 3, Lakewood Ranch Unit 4, according to the plat thereof recorded in Plat Book 45, Page 12, Manatee County, Florida").
Florida Plat Requirements
Florida's platting requirements are governed by Chapter 177, Florida Statutes. A plat must include:
- Lot dimensions and boundaries — Precise measurements of every lot in the subdivision.
- Street dedications — Public streets, alleys, and rights-of-way dedicated to the local government.
- Easements — Utility easements, drainage easements, and access easements shown on the plat.
- Common areas — Parks, retention ponds, and other areas dedicated to the HOA or public.
- Setback lines — Minimum building setbacks from property lines, if established by the plat.
- Surveyor's certification — The plat must be certified by a licensed Florida surveyor.
The plat must be approved by the local government (city or county) before recording. Once recorded, the plat is a permanent public record that cannot be changed without a replat or plat amendment.
Why Plat Maps Matter in Real Estate
The plat map is referenced in every deed, mortgage, and title insurance policy for properties in the subdivision. During a title search, the title examiner reviews the plat to verify the legal description, identify platted easements, and confirm that no plat restrictions affect the property.
