Zoning is a municipality's regulation of land uses and associated development. Property must be zoned correctly and satisfy development regulations prior to development permits being issued. The City of Sachse has many zoning districts, each with its own requirements and allowed uses. Development plans must comply with development standards of the Sachse Code of Ordinances.

Zoning restrictions ensure safer neighborhoods, more attractive business development, well-designed communities, and are the primary means to protecting Sachse's long range tax base. Zoning is also one of several tools Sachse utilizes in implementing its long range plans. The State of Texas delegates the authority and power to zone land to municipalities via Chapter 211 of the Texas Local Government Code.

Contacting the Planning Department is the first step if one desires to change the zoning on a tract of land. State law strictly governs the rezoning process through a series of legal notices, public hearings, and conformance with the Future Land Use Plan (FLUP). Factors influencing the outcome may also include compatibility with adjacent land uses, the proposed land use, recent zoning trends, adopted development policies, the recommendation of the Planning & Zoning Commission, and other relevant information. 

A plat is a map of a subdivision that represents a tract of land, showing the boundaries and dimensions of property lot lines, easements, and streets. It also establishes the lot, block, and subdivision name in real estate transactions. After a plat is approved by the City, it is filed with the County Clerk becoming a legal lot of record for which a building permit can be issued.

Generally, a plat is required to legally subdivide property and prior to issuance of a building permit. Important to note, a plat is not the survey required by mortgage companies when closing the sale of property.
