Unincorporated Areas
Most of Wood County Has No Zoning or Deed Restrictions
Land outside city limits in Wood County is generally unincorporated with no county-level zoning, meaning land use is largely unrestricted — but cities do have their own rules inside their boundaries and ETJ.
Texas counties cannot adopt general zoning laws. Wood County is no different. Unincorporated land — land outside any city — has no county zoning. You could build a home next to a feed lot or a business next to a farm. Deed restrictions written into your title may still apply, but those are private agreements between landowners, not county rules.
Cities like Quitman, Mineola, and Winnsboro have their own zoning inside city limits. They also have an ETJ. ETJ stands for extraterritorial jurisdiction. It is a buffer zone just outside city limits. Inside the ETJ, the city can apply some rules to new subdivision development. If you buy land near a city, check whether it sits inside that city's ETJ. Outside any ETJ, the county's subdivision standards still apply to new plats — but those are not the same as zoning.
