Piedmont Sewer Lateral Rules: A Permit Even for a Test

Piedmont has been in EBMUD's regional program since August 22, 2011, one of the first cities to join. EBMUD issues the certificate, but Piedmont adds two things of its own: a City building permit for every lateral job, even a test with no repairs, and the right to require an inspection when the City finds a problem.

Quick facts. Certificate: EBMUD Compliance Certificate. Owner's part: the whole lateral, from the house to the City main. City permit: a sewer building permit, required even for a test only. Inspections: City and EBMUD. Contact: Piedmont Public Works, (510) 420-3050.

You own the whole pipe

In Piedmont, the property owner maintains the entire private sewer lateral, from the house to the City's sewer main. That's the same as Oakland and different from Alameda and Albany, where owners stop at the property line. The City says private laterals make up about half of Piedmont's whole sanitary sewer system, which is why it pays so much attention to them.

Four things that trigger an inspection

Piedmont's Public Works Department lists four:

1. Selling the property
2. Remodeling that totals more than $100,000
3. Asking EBMUD to change the size of the water meter
4. A written notice from the City of Piedmont about problems it found in your lateral

The first three are the standard EBMUD triggers. The fourth is Piedmont's own. If you get a letter from the City, you don't have to be selling or remodeling to need the work done.

The building permit, even when nothing gets fixed

Any repair or full replacement of a lateral needs a City building permit. Piedmont goes one step further: if you're only having the EBMUD verification test done, with no repairs, you still need a building permit. The City says that's so it has a record of the test in its house files.

Piedmont's sewer permit comes in two subtypes, full replacement and partial replacement. When your contractor applies online, the City asks for:

• A site plan diagram showing the alignment of the lateral, every cleanout, the point of connection to the main, and the overall length
• Contractor or Owner-Builder Declarations

Incomplete applications take longer to issue, so it pays to have that diagram ready. New construction that needs a brand-new connection to the main may also need a separate encroachment permit and a sewer connection fee. The City publishes a full set of Piedmont Standard Details that contractors work from.

Two inspections, two agencies

Piedmont's inspectors make the code-required inspections on any sewer work. Separately, an EBMUD inspector has to witness the verification test, and EBMUD charges its own fee for that. The City notes your sewer contractor can arrange both.

A typical job looks like this:

1. Check your parcel on EBMUD's property search for an existing certificate.
2. Have a contractor camera the lateral and give you a written bid.
3. Your contractor pulls the Piedmont sewer building permit.
4. Repairs or replacement happen, with City inspections along the way.
5. Your contractor books the EBMUD inspection and sets up the air or water test, and EBMUD witnesses it.
6. Once it passes, print the EBMUD certificate. Make sure the City permit gets its final sign-off too.

Selling in Piedmont

The sale rule is EBMUD's. You need a Compliance Certificate to close escrow, or a Time Extension Certificate ($142 fee, $4,500 refundable deposit, and 180 days from the TEC issue date to finish). Since even an as-is test needs a City permit in Piedmont, leave time for that step and get bids before you list. Our sellers' guide covers who pays and which transfers are exempt.

What it costs

EBMUD's Compliance Certificate fee is $407 under fees effective July 1, 2026. We couldn't find a published amount for Piedmont's sewer building permit, so that is unconfirmed. Call Public Works or ask your contractor to list it as its own line on the bid.

Piedmont's lateral rules are in Piedmont Municipal Code Chapter 17A. For sewer backups in the public system, call Public Works at (510) 420-3050 during business hours, or Police Dispatch at (510) 420-3000 after hours.
