Buying a home in the Bay Area? You’ve probably heard your realtor mention sewer lateral compliance. It’s a requirement in many cities before a property can be sold. If you’re wondering what it means and what steps to take, you’re in the right place!
Discount Plumbing Rooter Inc. is your trusted partner for sewer lateral inspections, compliance paperwork, and repairs in San Francisco, San Mateo, and Marin Counties. We work directly with homeowners, realtors, and contractors to ensure all city requirements are met affordably and efficiently.
A sewer lateral is the underground pipe that connects your home or building to the city’s main sewer line. Over time, aging pipes can crack, clog, offset, or deteriorate due to age, tree roots, soil movement, or outdated materials.
Because damaged sewer laterals can lead to sewage backups, environmental contamination, and infrastructure issues, Bay Area cities now require sewer lateral compliance ordinances. Navigating the paperwork and sewer line inspections can be confusing, and that’s where we come in!
For over 30 years, Discount Plumbing has been the Bay Area’s go-to plumbing partner, trusted by homeowners, realtors, and lenders alike.
We work with nearly all major lenders and can arrange for the cost of your sewer project to be paid directly out of escrow. Our close relationships with local city inspectors mean we know exactly how to navigate the process, from permits to paperwork to inspections.
Most projects take just a few days from start to finish, though timing does vary slightly by city. We begin with a quick video camera inspection of your sewer line, then submit all required paperwork to the city on your behalf.
Now, here’s the honest truth: most older sewer lines don’t pass today’s compliance standards. But don’t worry, replacement is faster and easier than you think. We can usually begin within two weeks and finish in just one day. No delays, no disruption to your sale. Just think of it as one more closing cost and one less thing for you to stress about.
A sewer lateral ordinance is a city-mandated requirement that property owners verify the condition of their private sewer line. This typically involves a CCTV sewer video inspection and, if necessary, sewer line repair or replacement before compliance is granted.
These ordinances are designed to:
Most cities now require a CCTV sewer video inspection as part of their sewer line compliance process.
A CCTV sewer inspection uses a high-resolution camera to record the interior condition of your sewer lateral. The footage is reviewed to identify cracks, offsets, root intrusion, bellies, or collapsed sections. The inspection is then submitted to the city as part of the sewer line compliance process.
At Discount Plumbing, all sewer line inspections are performed using city-approved CCTV equipment and formatted to meet local submittal requirements.
