Alameda County & EBMUD Sewer Lateral Rules
Alameda County is served by several different sewer authorities. In much of the East Bay, the East Bay Municipal Utility District (EBMUD) Regional Private Sewer Lateral (PSL) Ordinance requires property owners to inspect, test, and — if necessary — repair or replace their sewer lateral to obtain a Compliance Certificate. But the Tri-Valley cities of Livermore, Pleasanton, and Dublin are served by their own local districts, so the rule depends on your address. Always confirm with the district that actually serves your property.
When Is a Sewer Lateral Certificate Required?
In the participating EBMUD service areas, the regional PSL Ordinance identifies specific triggers. Below are the commonly cited triggers — but the exact thresholds and whether they apply to your address should be verified with EBMUD or your local district before any transaction or construction work.
Common Triggers (Verify with District):
- Buying or selling a property — title transfer triggers the requirement in participating EBMUD service areas.
- Major remodeling — building permits for work valued above the district's threshold trigger an inspection.
- Changing water meter size — increasing your meter size can require lateral compliance.
- Recurring backups or root intrusion — a camera inspection often reveals whether repair or replacement is needed.
