Your sewer lateral is the private pipe that carries waste from your house out to the City's main sewer line in the street. In Stockton, the section closest to your house, the upper lateral, is the homeowner's responsibility. The lower lateral and the City main fall to the City of Stockton.
Stockton's municipal code, Chapter 13.50, spells it out: property owners have to test, inspect, maintain, repair, or replace their privately owned upper sewer laterals. After a sewer overflow caused by a lateral defect, the City can require you to bring that pipe up to current code, on the City's timeline, not yours.
Most people assume the City handles everything underground. It doesn't. A camera inspection is how you find out what shape your part of the line is in, before a backup or the City makes the decision for you. See our Stockton sewer lateral rules guide for the full breakdown.
