Who Maintains Sewer Lines in San Bruno?
The split between the city and the property owner, explained.
Published November 5, 2026 · San Bruno Drain Clean
If you are selling a San Bruno home built 50 or more years ago, the sewer lateral has to pass a city review before the sale can close. Here is how that works.

San Bruno Municipal Code chapter 10.13 requires residential properties originally built 50 or more years before a sale to have the sewer lateral inspected before the property transfers. The city began enforcing the requirement on May 8, 2015. The owner pays for a video inspection done to city standards and makes the video available to the city.
If the city finds the lateral defective, the owner must repair or replace it to the city's satisfaction before the transfer. Once the lateral is acceptable, the city issues a certificate of compliance. The city's San Bruno Point of Sale Sewer Lateral Requirement page lists the program description, the code, the application form, a FAQ and a flow chart of the sale process.

Call 24/7 (650) 360-4973The code defines the lateral as the pipe from the end of the building drain to the public sewer, ending at the wye or other connection to the main. The owner has exclusive responsibility for maintaining, repairing and replacing it, up to and including that wye. The city maintains the collector mains.
Cracked and root-filled laterals let groundwater and rain into the sewer system and can contribute to overflows. Inspecting older laterals when homes change hands is a steady way to find and fix them over time.

Call 24/7 (650) 360-4973The biggest mistake sellers make is waiting until escrow opens. A video takes an hour or two, but the city's review, any repair, permits and the final certificate all take time. Ordering the video before listing lets you plan repairs on your own schedule and tell buyers up front that the lateral is certified.
The code allows the owner to request a time extension of up to 180 days to complete the work after transfer. The request needs a fee and a $7,500 escrow deposit, and the owner may owe more than that amount if the work costs more. Check current details and forms with the city.
After a certificate of compliance is issued, the sale trigger does not apply again for five years. If you bought a home with a recently certified lateral and sell within that window, you may not need another inspection.

Call 24/7 (650) 360-4973Ask the contractor whether they record to the city's standards and have submitted point-of-sale videos in San Bruno before. Ask for the full video file, a written summary and, if defects are likely, a repair estimate based on the footage. See sewer lateral inspection for what the visit involves.
If you are buying an older San Bruno home, ask to see the lateral video and the certificate of compliance. Watch the video yourself. Ask what was repaired and keep the records. If the seller is using a time extension, understand what work remains and how it is funded.
Sellers often ask whether a newer replacement lateral still needs inspection, whether a video from a few years ago counts and what happens if a buyer waives contingencies. The code and the city's FAQ answer these; call the city before listing if you are unsure.

Call 24/7 (650) 360-4973A seller orders the video two weeks before listing. The city reviews it and notes a cracked joint near the sidewalk. The seller gets two quotes, chooses a spot repair, the contractor pulls the permit and does the work in a day, and the city issues the certificate. The listing goes live with a certified lateral, and escrow closes without a lateral delay. Starting early made the difference.
A local provider can record the video to city standards, explain the findings and quote any repair. Call (650) 360-4973.
The point-of-sale rule turns an invisible pipe into a line item in the sale. Handled early, it is a routine step. Handled late, it can delay closing. A video before listing is the simplest way to stay ahead.

Why slope matters underground and how to handle it.
The code places the inspection and any required repair on the owner, which is usually the seller. Buyers and sellers sometimes negotiate credits.
Check with the city; shared laterals and building types can change how the rule applies.
