Alameda Sewer Lateral Rules: You Own Half the Pipe

Alameda has been part of EBMUD's regional sewer lateral program since January 1, 2015, so the certificate, the test, and any time extension all come from EBMUD. What's different on the island is how much of the pipe is yours, the property line cleanout the City requires, and the City permits you pull before anyone digs.

Quick facts. Certificate: EBMUD Compliance Certificate. Owner's part: the upper lateral, from the building to the property line. City permits: a Building Permit, plus an Encroachment Permit in some cases. Extensions: EBMUD only. City contact: pwpermits@alamedaca.gov or (510) 747-7930.

When you need a certificate

The City points to the EBMUD triggers:

• Buying or selling a property
• Building or remodeling over $100,000
• Changing the size of your water meter

You can also fix the lateral and get a certificate voluntarily, for example if you keep getting backups. The City still recommends the certificate in that case, as proof the work holds.

The upper lateral is yours, the lower lateral is the City's

In Oakland and Piedmont, owners are responsible for the whole pipe out to the main. In Alameda, the owner handles the upper lateral, the part on private property. The City handles the lower lateral, from the property line to the sewer main. Only the upper lateral is tested for the EBMUD certificate here.

Two situations change that:

• Back yard or side yard mains. Under EBMUD's regional ordinance, if a lateral connects to a sewer main in a rear or side yard easement, the entire lateral, including the connection, counts as the upper lateral. Alameda's permit rules also treat these laterals differently (see below).
• Condos and HOAs. The split can be different. EBMUD has separate guidelines for condominiums and other common interest developments.

The property line cleanout

If you don't already have one, the City requires a cleanout on the lateral at the property line. Getting the spot right matters, because Alameda's property line setbacks vary block by block:

• The City publishes a property line setback schematic with an index sheet. Find your block's map and read the setback from the face of the curb. That's where the cleanout goes.
• Any change from that location needs Public Works approval in advance.
• The City has standard details for 4-inch and for 6- and 8-inch cleanouts.
• If your lateral runs to a back yard main or other easement, contact Public Works for the easement location and where to put the cleanout.

When in doubt, the City says to call Public Works and have staff help site it.

City permits: one or two

These are separate from the EBMUD certificate, and you need them before work starts.

• Building Permit (always). Required for ground plumbing repairs and replacements. Apply through the City's Permit Center. Work has to follow the California Plumbing Code as amended by Alameda Municipal Code Chapter 13-6.
• Encroachment Permit (sometimes). Only needed when the cleanout goes in the sidewalk or parkway strip, or when the lateral goes to a side or back yard main. A cleanout on the private side of the property line doesn't need one.

The City says the work should be done by a contractor with a C-36 (plumbing) or C-42 (sanitation system) license. The maintenance standards themselves are in Alameda Municipal Code Section 18-5 and EBMUD's ordinance: free of roots and grease, watertight, no cracks or missing pieces, a capped cleanout, and no roof drains, area drains, or sump pumps tied in.

Step by step

1. Check your parcel on EBMUD's property search. You may already have a valid certificate.
2. Have a contractor camera the upper lateral and give you a bid.
3. Pull the Building Permit, and the Encroachment Permit if your job needs one.
4. Repair or replace the upper lateral and install the property line cleanout if it's missing.
5. Book the EBMUD inspection online and pay the Compliance Certificate fee. Your contractor sets up the air or water test, and EBMUD witnesses it.
6. Print the certificate once it passes.

Extensions come from EBMUD, not the City

If you're selling and can't finish before closing, apply to EBMUD for a Time Extension Certificate. It's a $142 fee plus a $4,500 refundable deposit at title transfer, and the certificate is due within 180 days of the TEC issue date. The City of Alameda has no authority to grant an extension. Details are in our guide for sellers.

Older Alameda certificates

If your parcel has a valid, unexpired certificate or similar documentation issued by the City of Alameda, EBMUD may issue an Exemption Certificate. EBMUD checks the replacement and sign-off date with the City, and the exemption expires on the same date as the City document.

Alameda Point

Properties at Alameda Point follow their own process. Contact City Engineering first. EBMUD requires an Alameda Point PSL Form signed by the City before it will schedule the special certification appointment, whether you're a tenant or an owner.

What it costs

EBMUD's Compliance Certificate fee is $407 under fees effective July 1, 2026. We haven't found a published amount for Alameda's Building Permit or Encroachment Permit on lateral jobs, so those are unconfirmed. Because you're only replacing the upper lateral, compare bids carefully and make sure each one covers the same length of pipe and the cleanout. Our cost guide lists EBMUD's other fees.
