Use the map before assuming Tyler zoning applies

A Tyler mailing address does not prove you are inside Tyler. Many homes with Tyler mail sit on unincorporated Smith County land. The city limit line is what matters. It decides whether Tyler zoning, setbacks, and permits reach the parcel.

Start with SmithCountyMapSite.org and check which side of the line the address is on. If it is inside the city, the zoning class matters next. Setbacks and allowed uses follow that class, along with the city's code tables.

The difference shows up when you buy land, place a shed, run a home business, or set a fence post. Inside Tyler, you are on the city permit track. Outside it, you deal with county rules, utility easements, and any subdivision limits tied to the parcel.
