Who is responsible for which part

The property owner is responsible for the entire lateral, upper and lower, from the home to the public main - except in Alameda and Albany, where the programme covers the upper lateral only.

The property owner
The programme states that "the property owner is responsible for the entire PSL from their home to the public sewer main (upper and lower lateral), with the exception of Alameda and Albany where the responsibility ends at the property line or curbside cleanout (i.e. upper lateral only)", and describes the same span again as "the entire lateral from the building cleanout to the public sewer main under the street". So in Oakland, Emeryville and Piedmont the run beneath the road is the owner's. In Alameda and Albany the programme reaches the upper lateral only. Both of those cities have answered the rest themselves and the answer is in your favour - see below.
What decides which applies
Which city you are in changes the answer, and in two of the five it changes it by the length of the road. The programme's own page stops at the upper lateral for Alameda and Albany without saying who has the rest; each of those cities says so itself. Alameda's sewer system management plan states that "the property owner owns the entire service lateral from the building to the connection to the City's sewer main; however, the City takes responsibility for maintenance and replacement of the lower portion of the lateral", and that "the upper lateral remains the responsibility of the private property owner" - the City rehabilitating a lower lateral when it rehabilitates the main it connects to, or when the lower lateral fails, whichever comes first. Albany takes the lower lateral too, from the kerb to the main; its own page for householders is the place to have that confirmed. So if you are in Alameda or Albany, the run under the road is the City's to keep up and the part across your own land is yours - ring the City before you ring a plumber. In Oakland, Emeryville and Piedmont the whole run is yours, and Piedmont's own plan puts the connection at the main on you as well. One caution for Alameda: the City's code still reads that "property owners own the entire sewer lateral and must maintain, repair and replace all sewer laterals associated with their parcels", which is broader than what its plan says the City does - the plan is the more recent statement of what the City will actually do, and the code has not caught up.
East Bay Regional Private Sewer Lateral Program, Frequently Asked Questions

What is required

Some of these requirements are issued by East Bay Regional Private Sewer Lateral Program rather than by Piedmont.

  • When you askPermit

    The City of Piedmont issues a Sewer Building Permit, stating that "you need a permit if you are working on the sewer line that connects your building (private sewer lateral) to the City's main line". It is applied for in two subtypes, full replacement and partial replacement. The City adds that "new construction that requires a new connection to an existing sewer main may require a separate encroachment permit and the payment of a sewer connection fee". This is separate from the East Bay Regional Private Sewer Lateral Program's compliance certificate.

    What to do: Decide with your contractor whether the work is a full or partial replacement before applying, since Piedmont's permit asks and the answer changes how long the resulting certificate lasts. If the work is a new connection rather than a replacement, ask about the encroachment permit and the connection fee as well. The regional programme's compliance certificate is separate from the City's permit.

    Why this matters

    Piedmont asks at the application stage whether you are replacing the whole lateral or part of it, where most authorities issue one permit for any work on the pipe. That distinction follows the job afterwards: under the regional programme a compliance certificate is worth twenty years after a full replacement and seven after a repair, so the choice made on the permit form is the choice that decides when the next owner has to do this again. A brand-new connection is a different transaction still, carrying an encroachment permit and a connection fee that a replacement does not.

  • When you remodelCertificate

    Where a permit is sought for new construction or for remodelling costing more than $100,000, a Compliance Certificate is required before the final permit or approval is obtained.

    What to do: Check whether a current certificate or exemption already covers this property through the East Bay Regional Private Sewer Lateral Program before planning the permit timeline around an inspection.

    Why this matters

    This is the highest threshold of the covered programmes - Berkeley's own ordinance, which this one does not cover, fires at $60,000, and three Marin districts at $50,000. It is also required later in the process than its neighbours demand: the certificate is needed before final approval rather than before the permit is issued. A certificate is valid twenty years after a complete replacement and seven years otherwise, and an exemption may be available where the lateral was fully replaced within the last ten years.

  • When you sellExtension available

    A 180-day extension is available when buying or selling: if a Compliance Certificate cannot be obtained before title transfers, a Time Extension Certificate allows 180 days for the work, and is valid only when returned with a $4,500 deposit at title transfer.

    What to do: If the lateral cannot be certified before completion, ask the East Bay Regional Private Sewer Lateral Program about a Time Extension Certificate, and agree in writing which party will receive the $4,500 refund.

    Why this matters

    The certificate requirement reads as an absolute bar on closing escrow, and it is not one. The $4,500 is a deposit rather than a fee - the programme states it "will be released to the designated party when compliance is achieved" and is refunded if compliance is met within the 180 days - but it still has to be found at title transfer, and the Time Extension Certificate itself carries its own charge.

  • When you sellCertificate

    A Compliance Certificate is required to close escrow when a property is sold or transferred. A certificate is valid twenty years after a complete replacement and seven years otherwise.

    What to do: Check whether a current certificate or exemption already covers this property through the East Bay Regional Private Sewer Lateral Program before arranging an inspection.

    Why this matters

    An exemption may be available if the sewer lateral was fully replaced within the last ten years, or if an unexpired certificate from another agency already covers the property. Whether one already exists is not something an address lookup can answer - ask the programme, which holds the certificate records.

Your other pipe has a different answer

The drinking water line coming into your property is a separate pipe, run by a separate authority, and who is responsible for it is decided separately. Your sewer lateral is yours to the main; your water line stops being yours at the meter.
