Private Sewer Lateral Program

The Castro Valley Sanitary District (CVSan’s) Board of Directors adopted a Private Sewer Lateral Ordinance (Ordinance No. 179) on September 4, 2018. Effective July 1, 2019, any property being sold is required to comply with Ordinance No. 179.


Any commercial, industrial, and residential property being sold in Castro Valley Sanitary District’s boundaries is required to have a Sewer Lateral Compliance Certificate before the close of escrow. If a Certificate cannot be obtained before the close of escrow, the buyer or seller will have the option to complete the work after the close of escrow through CVSan’s time-extension options.

Use CVSan’s online permit portal to check if your property has a valid Sewer Lateral Compliance Certificate in CVSan’s database.
If the property owner already knows that the sewer lateral’s condition will require a full replacement, continue to Step 4.
If the property owner is unsure what condition the sewer lateral is in, continue to Step 1.

Step 1: Hire a Contractor to Perform a CCTV Inspection
If the property does not have a valid Sewer Lateral Compliance Certificate and the property owner is not sure what the condition of the lateral is, the property’s sewer lateral must be inspected by a contractor through closed-circuit television (CCTV). After a contractor has been hired, continue to Step 2.

Step 2: Pay for and Schedule a CVSan CCTV Permit
The contractor’s CCTV inspection must be witnessed by a CVSan inspector. To schedule an inspection appointment and pay for a CVSan CCTV permit, use CVSan’s online permit portal or CVSan’s main office located at 21040 Marshall Street, Castro Valley.  The CVSan CCTV permit is $230 and covers the cost of CVSan’s staff time to review the CCTV video. After scheduling and paying for the permit and inspection, continue to Step 3.

Step 3: Receive the Inspection Results

After the CCTV inspection is complete, CVSan inspectors will review the CCTV video to determine if the sewer lateral passed or failed the inspection based on CVSan’s standard criteria. If the sewer lateral passes the inspection, CVSan will issue a Compliance Certificate that is valid for 10 years and it can be given to the buyer with all other certifications necessary for selling a property. If the property does not pass the inspection, continue to Step 4.

Step 4: Complete Necessary Repairs Before or After Property is Sold
If CVSan’s inspectors determine that the sewer lateral needs to be repaired or replaced, the work may be completed before or after the close of escrow. The sewer contractor must obtain a CVSan sewer repair permit before beginning any repair work. The CVSan sewer repair permit is $175 and can be obtained online through the online permit portal or in person at CVSan’s main office located at 21040 Marshall Street, Castro Valley, CA 94546. If the sewer lateral requires a complete replacement, then CVSan will issue a Sewer Lateral Compliance Certificate that is valid for 30 years after the work is completed and the repair permit has been signed by a CVSan inspector. If the CCTV inspection determines that only a portion of the sewer lateral requires repairs, then CVSan will issue a Sewer Lateral Compliance Certificate that is valid for 10 years after the work is completed and the repair permit has been signed by a CVSan inspector.

Homes Built After 1960 Have a Better Chance of Passing the CCTV Inspection
CVSan encourages property owners whose buildings were built after 1960 to hire a contractor to perform a CCTV inspection. Recent inspection data shows the more recently your building was built the greater likelihood that the building may pass the CCTV inspection, qualifying you to obtain a 10-year sewer lateral compliance certificate. The figure below compares the CCTV inspection review pass rate to the building age. Since July 1, 2019, the CCTV inspection review found that 359 of the 641 sewer lateral CCTV inspections, or 64 percent, passed the CCTV inspection review for a 10-year sewer lateral compliance certificate.
