City vs. County Rules Practical

Many Denton County addresses are inside a city's planning zone, not the city itself

Denton County Home & Property

A Texas city can reach beyond its own limits with an extraterritorial jurisdiction, or ETJ. Think of it as a planning ring around town. Denton, Frisco, and Lewisville all have large ETJs in Denton County. Land inside one may still pay county taxes, but the nearby city can shape how it is divided or built.

In an ETJ, the stricter city or county rule can control. A plat may need sign-off from both. The county GIS map shows where the lines fall. If a parcel sits in an ETJ, Denton County Development Services can help sort out whose rules apply.
