Most larger sewer line repair jobs in Amarillo need a permit and inspection; repairs often do not. Here is what to check before work starts.
Check the official Amarillo permit portal: https://www.amarillo.gov/departments/public-safety-and-organizational-services/building-safety. Replacements, re-piping and new installs typically need a permit; simple repairs usually do not. Ask the contractor in writing who will handle filing and inspection, and whether those fees are included.

Licence and certification requirements depend on the work and jurisdiction. Ask which requirement applies, then verify the provider at the official lookup before work begins.
