What Is a Plat?

A plat is a legal map that establishes lots, easements, rights-of-way, and other property features. Plats are commonly required when land is subdivided for sale or development.

A replat modifies an existing recorded plat and is often used to adjust lot lines, combine lots, create additional lots, modify easements, or redevelop property.

When Is a Plat Required?

A plat may be required when dividing property into multiple lots, creating a subdivision, developing residential or commercial property, building on unplatted land, or modifying an existing subdivision.

Requirements vary depending on the property's location, utility availability, access, floodplain conditions, and whether the property is located within a city's ETJ.

The Platting Process

Most projects begin with a boundary survey and, when needed, a topographic survey. A licensed surveyor then prepares the proposed plat for review.

The plat is reviewed for compliance with subdivision regulations, drainage requirements, access standards, and utility considerations. Review comments may require revisions before final approval and recording.

Once approved and recorded, the plat becomes the official legal document governing the lots, easements, and rights-of-way shown on the map.

Common Reasons for a Replat

  • Split a large lot
  • Combine adjacent lots
  • Adjust property boundaries
  • Create additional buildable lots
  • Redevelop existing property
