How long does a sewer lateral last?

It depends heavily on material. Clay and cast iron laterals, common on pre-1970s houses across Sonoma and Marin, are typically at or past the end of their service life now and are the ones that show root intrusion at every joint. Modern ABS and PVC lines have a far longer expected life. Several Marin districts use age as a trigger in their own ordinances — Sonoma Valley's lets the district call in any lateral 30 years or older.

Do I need a permit to replace a sewer lateral?

For work connecting to the public sewer, yes. Permit Sonoma lists building sewers, side sewers, laterals, mains and manholes under its sanitation sewer construction permit, and its schedule shows a $257 plan check for a sewer line from the main to a building. In Marin the serving sanitary district administers it, and several also require a compliance certificate afterwards.
