To protect the water quality of creeks, watersheds, and the San Francisco Bay, the City of Berkeley Municipal Code (BMC) includes provisions related to the maintenance and repair of private sewer laterals. It is estimated that half the water that enters the City’s sewers during wet weather comes from deficient private sewer laterals (PSLs) and from downspouts and yard area drains that are directly connected to sanitary sewer laterals.

Since October 2006, property owners have been required to obtain a Sewer Lateral Certificate of Compliance (SLC) prior to transfer or sale of property, or before obtaining a building permit for major construction projects such as remodels. The City amended its private sewer lateral ordinance (BMC Chapter 17.24), effective November 3, 2014 to comply with requirements mandated by the U.S. Environmental Protection Agency (EPA) and State and Regional Water Boards. Under these requirements, the City’s PSL ordinance must be “no less stringent” than the Regional PSL Ordinance adopted by the East Bay Municipal Utility District (EBMUD), which applies to most of the communities within the EBMUD wastewater service area.

All property owners -- including condominiums and other developments with shared laterals -- are required to obtain a Sewer Lateral Certificate (SLC) under the following conditions:

  1. By close of escrow for the transfer or sale of property (with some exceptions), unless a 6-month extension is granted prior to closing; OR
  2. When obtaining a Building Permit for construction or remodel valued over $60,000; OR
  3. When the City finds that the PSL may be a public nuisance; OR
  4. When a property owner elects to repair or replace their PSL.

In order to obtain a Sewer Lateral Certificate (SLC), all property owners must first obtain a PSL permit and demonstrate the PSL is in satisfactory condition, unless the property owner already has a valid SLC or can demonstrate that the PSL was replaced in the last 20 years, as evidenced by a permit signed off by a City Inspector.

After obtaining the permit and passing a required Verification Test, all property owners will be issued a SLC.

Note: CCTV reports to document testing and compliance are no longer accepted.
