02 What you need to know
Who is responsible for the sewer lateral in Los Angeles
The pipe that connects your house to the public sewer main is called a sewer lateral. It serves only your property, so it’s generally treated as a private line, not part of the public system.
City of Los Angeles
LA Sanitation describes the lateral in two parts: the upper lateral, from your building to the property line, and the lower lateral, from the property line out to the City’s main line, often under the sidewalk and street. The City says property owners are responsible for maintaining and repairing the entire lateral, including root blockages in the public right-of-way.
Other cities and districts
Responsibility depends on where the property is. Unincorporated LA County uses a similar rule under county code. Other cities and sanitation agencies may draw the line differently, for example at the property line or at a cleanout. Check with the city or sewer agency that serves the address. Don’t assume the rule from your last home applies.
Common problems in older LA homes
- Clay pipe with joints that crack or separate over time
- Orangeburg pipe, a fiber pipe used in some mid-century homes that can deform and collapse
- Root intrusion from street trees and landscaping
- Offsets, where pipe sections shift out of line
- Bellies, sagging sections where water and waste collect
A standard home inspection usually doesn’t include a look inside the sewer line. That takes a separate sewer camera inspection (also called a sewer scope), where a contractor runs a video camera through the pipe.
03 Real-world example
Example: what a sewer scope can reveal during escrow
Say you’re buying a 1950s house in the City of Los Angeles. The general inspection looks clean. You order a sewer camera inspection during your inspection contingency, the window when you can still negotiate or cancel.
The video shows roots at several clay joints and a cracked section near the street. Depending on what’s found, the fix could look like one of these:
| Finding | Typical fix | Cost picture |
|---|---|---|
| Light roots, pipe intact | Cleaning or root cutting | Can be a few hundred dollars |
| One damaged section | Spot repair | Can run into the thousands |
| Widespread cracks, pipe still passable | Pipe lining (a new liner cured inside the old pipe) | Often many thousands |
| Collapse or damage under the street | Full replacement, possibly opening the street | Can reach tens of thousands |
Assumptions: general illustration only. Actual costs vary widely with pipe length, depth, material, access, method and whether work in the public right-of-way is needed. Get written bids from licensed contractors.
With the video and a bid in hand, you can ask the seller to repair, give a credit, or reduce the price. Learn how credits work in seller credits and your mortgage.
04 What most people overlook
What buyers overlook about sewer line repairs
- Permits matter. In the City of Los Angeles, lateral work in the public right-of-way generally requires a permit from the Bureau of Engineering. Ask whether past repairs were permitted, and make sure any new work is.
- The City doesn’t pay for it. The City says it doesn’t provide financial assistance for lateral repair or replacement.
- Get the video, not just the summary. Ask for the recording and the footage location of any defects, so a second contractor can bid on the same findings.
- Timing is everything. Once your contingencies are removed, your leverage is mostly gone.
- Credits have limits. Seller credits can usually go toward closing costs, not cash for repairs, and lenders cap how much is allowed.
A sewer camera inspection usually costs far less than the repair it can uncover. Schedule it with your other inspections.
05 How I’d approach it
How I’d handle the sewer line on an older LA home
On an older Los Angeles house, I treat the sewer scope as part of the inspection, not an optional extra.
First, I ask your agent to schedule a sewer camera inspection early in the inspection period, especially for older homes or properties with mature trees near the line.
Second, if there’s a problem, I want a written bid before we negotiate. A specific number lets us decide whether a repair, a credit or a price change works best with your loan. I run the options through the Loan Estimate calculator so you can see the effect on cash to close.
Third, if you’re buying anyway and doing the work later, I make sure your budget has room for it. That ties into your broader home maintenance budget.
