Sewer lateral inspection in the East Bay
Reviewed by East Bay Sewer Inspection staff
In the East Bay, a sewer lateral inspection usually means two steps: a plumbing contractor checks the private sewer lateral (typically with a video camera), then an EBMUD inspector watches a pressure test (the verification test). Pass the test and EBMUD issues a Compliance Certificate. Berkeley runs its own program and its own city inspector watches the test.
What is a private sewer lateral?
It is the pipe that carries waste from a building's plumbing to the public sewer main, usually in the street.
EBMUD splits it into an upper lateral (building cleanout to curbside cleanout) and a lower lateral (curbside cleanout to the main). Owners are responsible for the whole lateral, except in Alameda and Albany, where they are responsible only for the upper lateral. According to EBMUD, many East Bay homes were built before 1950 and still have their original laterals. These are often clay pipes that crack, separate or let in tree roots (EBMUD guidebook).
When is a sewer lateral inspection required?
In the EBMUD program, you need a Compliance Certificate when you buy or sell a property, build or remodel for more than $100,000, or change your water meter size.
The EBMUD program covers Alameda, Albany, Emeryville, Oakland, Piedmont, El Cerrito, Kensington and the Richmond Annex. Some title transfers are exempt, for example to a spouse or into a living trust. EBMUD issues an Exemption Certificate for these. In a sale, the buyer and seller decide who obtains the certificate. If the work cannot be done before closing, a Time Extension Certificate gives 180 days. It requires a $4,500 deposit, which is refunded once the certificate is issued (EBMUD guidebook).
Berkeley is separate. Its fact sheet says a Sewer Lateral Certificate is needed by close of escrow on a sale, with a building permit for work valued over $60,000, when the City finds the lateral may be a public nuisance, or when an owner chooses to repair or replace it (Berkeley fact sheet). See Berkeley and all cities.
What does the contractor check?
The contractor looks for leaks, other defects and illicit connections, then tells you whether the lateral can pass the test as is, needs a repair, or needs to be replaced.
The evaluation usually starts with a video (CCTV) inspection. EBMUD recommends that the owner be there when the camera is run, so you can see the pipe and ask questions (EBMUD guidebook). EBMUD also recommends getting written bids from at least three contractors (EBMUD bid guidance).
- Illicit connections: any connection that could carry stormwater into the sewer, such as downspouts tied into the sewer, uncovered outdoor sinks and drains, has to be fixed (EBMUD bid guidance).
- Gas line cross bores: when PG&E installed new gas lines, some laterals were pierced or bored through. EBMUD says a CCTV review should look for signs of a cross bore. If you suspect one, call PG&E at (800) 743-5000 (EBMUD).
- Shared laterals and private mains: if the lateral connects to a private shared main, you may have to pressure test all pipe between the building and the public main (EBMUD bid guidance).
How does the EBMUD verification test work?
The contractor sets up and runs an air or water pressure test on the lateral, and an EBMUD inspector watches it on site. EBMUD also checks that there are no illicit connections.
- If work is needed, get city permits before starting. In Emeryville, a permit is required even to test the lateral as is (EBMUD).
- Book the test and pay the Compliance Certificate fee online through the EBMUD PSL site (EBMUD).
- On the day, the lateral must be ready: work complete, test equipment set up and the lateral already pressurized with water or air. If it is not, the return visit costs $140 (EBMUD fee guidelines).
- Allow access to the whole parcel so the inspector can look for possible sources of rainwater to the sewer. Unlock gates and secure animals (EBMUD bid guidance).
- Once the lateral passes, print the certificate from the EBMUD PSL site. Sellers give a copy to the buyer before title transfer (EBMUD).
EBMUD lists common setup failures that lead to a $140 return visit. They include a water standpipe shorter than 5 feet or not at the highest point of the section being tested, a dial air gauge not in 0.1 psi increments, plugs not placed close enough to the building or main, and cleanouts left out of the test (EBMUD fee guidelines).
What does the inspection cost?
EBMUD's fee to witness the test and issue the certificate is $407 for one lateral. The contractor's camera inspection, test setup and any repair are priced separately by each contractor.
| EBMUD fee (effective July 1, 2026) | Amount |
|---|---|
| Compliance Certificate (includes witnessing one verification test for one lateral) | $407 |
| Extra lateral, manhole or verification test | $140 each |
| Inspection rescheduling (rescheduled after 7 a.m. on the day, contractor not ready, no show, failed test or failed setup) | $140 |
| Off-hours verification test | $289 minimum |
| Specific appointment time | $374 |
| Time Extension Certificate | $142, plus a $4,500 refundable deposit at title transfer |

For repair and replacement costs, see sewer lateral replacement cost.
How long does a Compliance Certificate last?
A certificate lasts 20 years if the lateral was completely replaced, or 7 years if it was repaired or passed without replacement.
EBMUD says the certificate only shows that the tested part of the lateral passed on the test date. It is not a guarantee of the pipe's future condition (EBMUD). Berkeley also issues 20-year certificates for full replacements and 7-year certificates otherwise, and no longer accepts CCTV videos as proof of compliance (Berkeley fact sheet).
How do I find a contractor?
EBMUD publishes a courtesy list of contractors but does not endorse any of them. Check the contractor's licence with the CSLB and ask for references.

Frequently asked questions
Do I need a sewer lateral inspection to sell a house in Oakland?
Yes. In the EBMUD program area, which includes Oakland, the property needs a Compliance Certificate, an Exemption Certificate or a Time Extension Certificate before title transfer.
Who performs the verification test?
Your contractor sets up and performs the air or water pressure test. An EBMUD inspector, or in Berkeley a City inspector, witnesses it on site.
What happens if the lateral fails the test?
The contractor repairs or replaces the lateral and the test is booked again. EBMUD charges a $140 rescheduling fee for the return inspection after a failed test or failed setup.
Does Berkeley accept a video inspection as proof?
No. Berkeley's fact sheet says the City no longer accepts CCTV submissions as proof of compliance. A verification test is required.
