State guide
North Carolina
North Carolina does not appear to set a single statewide ownership rule for every private sewer lateral; current official materials point residents to local utility rules and local permitting programs. The state DEQ says local governments and utilities may run delegated permitting programs for public and private sewer systems, while city guidance in Raleigh and Durham shows homeowner responsibility often extends to the lateral up to the public system or right-of-way.

What to do next
- Ask your city or sewer utility to state in writing where the public system ends and your private lateral begins before authorizing excavation.
- If work will touch the street, sidewalk, easement, or right-of-way, check both the local utility permit and any ROW permit requirements first.
- In Durham or Raleigh, start with the utility’s sewer maintenance or engineering contacts before hiring a contractor if the blockage location is uncertain.
