What Santa Cruz Homeowners Need to Know Before Selling: The City’s Sewer Lateral Ordinance

If you’re planning to sell a home in Santa Cruz, there’s a requirement that catches a lot of homeowners off guard: your sewer lateral has to be inspected, and possibly repaired, before the sale can close. Here’s what the ordinance actually requires, what it costs, and how to avoid it becoming a last-minute scramble during escrow.

What Is a Sewer Lateral?

A sewer lateral is the pipe that runs from your house to the city’s sewer main in the street. Unlike the main line itself, the lateral — including the section under your yard, your driveway, and even the sidewalk — is entirely your responsibility to maintain and repair. The city doesn’t own it, doesn’t maintain it, and won’t fix it if it fails.

What the Ordinance Requires

The City of Santa Cruz updated its Sanitary Sewer System Ordinance in 2018. It covers three things:

• Sewer spills. If your property has a sewer spill, you’re responsible for stopping it immediately. Failing to make timely repairs can mean fines.
• Private system inspection. If your property has a private sewer collection system or pumps (common for apartment buildings, HOAs, or some businesses), it needs to pass inspection every 10 years, with regular cleaning in between.
• Point of sale. Before you sell your property, your sewer lateral has to be inspected by a licensed plumber, any necessary repairs made, and an inspection form submitted to verify compliance.

One detail worth knowing: within Santa Cruz County’s unincorporated areas, the responsibility for submitting the inspection report and video sometimes falls to the plumber rather than the homeowner. Within city limits specifically, the homeowner is the one required to submit it. If you’re not sure which applies to your property, we can walk you through it.

What Happens If You Can’t Complete Repairs Before Closing

If an inspection turns up repairs that can’t be finished before escrow closes, sellers and buyers can agree to transfer that responsibility to the buyer using the proper form, giving the buyer time after closing to complete the work. Without that paperwork in place, repairs generally need to be finished before the sale can close — which is exactly why it pays to get the inspection done early rather than during a tight escrow window.

What It Costs

A sewer lateral inspection typically runs around $200–$300 if your home already has an accessible cleanout. If your home doesn’t have one, expect a higher cost, since installing a cleanout is often necessary to bring the property into compliance in the first place. If the inspection finds damage — cracks, root intrusion, or a misaligned joint are the most common culprits in Santa Cruz’s older housing stock — repair costs vary based on what’s found.
