Key Takeaways
Each inspection follows the same steps.
If heavy buildup blocks the camera, the line may need cleaning first. We tell you before doing it.
| Finding | What it may mean | Typical next step |
|---|---|---|
| Clean, round pipe | Lateral in good shape | Keep the record |
| Fine roots at a joint | Small gap at a joint | Cleaning, recheck later |
| Heavy roots | Larger opening in the pipe | Cleaning, repair discussion |
| Offset joint | Sections have shifted | Repair options |
| Sag with standing water | Pipe has settled | Repair options |
| Crack or break | Pipe is failing | Repair or replacement quote |
A clean result is good news and a useful document. A defect is better found on your schedule than during a sale.
A little preparation makes the inspection faster to schedule and easier to use.
Before you list your home:
Before you pull a remodel permit:
If no cleanout exists, we explain the access options before the visit. Some homes need a cleanout installed before a full inspection is possible, and that work has its own permit question, which we confirm with the City.
You should not have to guess what the video means. After every inspection, we provide:
We do not pad the findings. If the pipe is in good shape, we say so, and you keep a record that may help with the five-year exception later.
The owner is. The City states that property owners maintain their private sewer lateral. That pipe runs from the building to the City main, and the City includes the wye connection at the main and any part under the public right-of-way.
The City does not provide sewer lateral inspections and cannot recommend service providers. That is why owners hire a contractor for this work.
If the footage shows the lateral needs repair, our trenchless pipe repair in San Mateo page covers the repair options and the City’s cost-sharing program for full replacement.
Not every inspection is required. Many owners call us for these reasons:
A recurring clog often starts with drain cleaning in San Mateo, followed by a camera run to see the cause.
The inspection itself looks inside the pipe. If the footage leads to repair work in the public right-of-way or at the City main, that work needs an encroachment permit from the City. We include that step in any repair plan.
Works Plumbing has been family owned and operated since 2009. We inspect laterals across San Mateo, from North Shoreview and Shoreview to Sunnybrae and Parkside.

Do I need a sewer lateral inspection to sell my San Mateo home?
In most cases, yes. San Mateo Municipal Code 7.38.432 requires a lateral inspection at the sale of real property, unless an exception applies, such as a clean inspection in the past five years.
My San Mateo remodel is over $90,000. Does that trigger an inspection?
Yes, if it requires a building permit for an addition, alteration, or remodel valued at $90,000 or more. Emergency repair permits are exempt.
I replaced my lateral 15 years ago. Do I still need an inspection?
Not if the lateral was completely replaced within the past 25 years and received final sign-off under a City permit. Find the permit record before you list or remodel.
Will the City of San Mateo inspect my lateral?
No. The City does not provide sewer lateral inspections and cannot recommend service providers. Property owners hire a contractor.
Does San Mateo’s cost-share program pay for a camera inspection?
No. The Citywide Private Lateral Cost Sharing Program does not cover CCTV inspections. It covers full lateral replacement only.
Does the inspection rule apply to my San Mateo apartment building after an overflow?
Yes, if a lateral backup or blockage caused a sanitary sewer overflow at a commercial or multifamily building. That event triggers a required inspection.
Whether you are selling, remodeling, or chasing a clog, know what is in the pipe. Book a sewer camera inspection in San Mateo and get clear footage and clear answers.

A look at real Works jobs around the Peninsula.
San Mateo is one of the Peninsula cities that ties lateral inspections to real estate and construction. The City of San Mateo Private Sewer Lateral Ordinance page explains the rule. City Council amended Municipal Code 7.38.432 on February 3, 2020, and the changes took effect December 1, 2020.
An inspection is required on any of these events:
There are exceptions. An inspection is not required if one was done within the past five years and found no repairs needed, or found repairs that have since been completed. A lateral completely replaced within the past 25 years, with final sign-off under a City permit, is also exempt.
Here is what that means in practice. The remodel trigger catches owners who are not selling at all. A kitchen and bath project can cross the $90,000 line and add a sewer step to the permit. Planning the inspection early keeps it from holding up the project.
The exceptions also reward good records. If your last inspection is within five years and was clean, keep that report where you can find it. If you are weighing a full replacement, the 25-year exemption is part of the value. We at Works Plumbing explain which trigger or exemption applies before we inspect.
