Short answer
Replacing a home's sewer line needs a plumbing permit in Texas cities — Plano lists replacing sewer lines as permitted work, and Fort Worth requires a plumbing permit for repairing plumbing — and sewer line work at a home is licensed plumbing work under state law. Connections to the city main or work in the right-of-way can bring the city's utility or public works staff into the job.
The general picture
In Texas, work on a home's sewer line is licensed plumbing work, so a licensed master plumber pulls the permit. Cities add their own layers: Plano lists replacing sewer lines as permitted work, Fort Worth requires a plumbing permit to repair plumbing, and connections in the street can involve the city's utility or public works staff. Plan for an open-trench inspection before backfill. See the verified notes for Fort Worth and Plano.

Common reasons sewer line replacement applications get bounced
Code-rooted patterns across Texas — not a city-specific rejection rate.
- Insufficient slope or cover over the pipe
- Cleanouts missing at required locations
- Trench backfilled before inspection
- Right-of-way work without the city's separate approval
- Contractor not registered with the city where registration is required

Licensing — who can pull it
Sewer line work at a Texas home is done by a TSBPE-licensed plumber, with a Responsible Master Plumber pulling the permit. Some cities add registration categories for private utility contractors working between the right-of-way and the building.
