Inside Tyler, home projects run through city building permits

The story that Smith County is permit-free gets people in trouble the moment their lot turns out to sit inside Tyler. The county does keep its hands off rural construction beyond subdivision rules, but cross the city line and the city's rules take over completely, and Tyler runs every permit and plan set electronically through TylerInspections.com.

The city's property-owner forms page covers the whole spread: residential and commercial permits, driveway and sidewalk details, floodplain development permits, and a separate batch of Lake Tyler forms. Tyler builds to adopted codes plus its own local amendments, and inspectors enforce them, so the standards inside the city limits are real, not a formality.

Which means the first move on any project is settling jurisdiction. Pin down whether the address is in Tyler or out in unincorporated Smith County, then go to whichever office, city or county, actually holds authority over that dirt.
