How Much Does Sewer Line Replacement Cost in Los Angeles?
Budgeting ranges by method, the City fees that apply when work reaches the street, and the handful of things that actually move the number.
By Angeleno Sewer Line Repair · Updated
Full sewer line replacement in Los Angeles typically runs $5,000 to $25,000 or more for an open-trench job, and $6,000–$15,000 to line a lateral of about 50 feet, as of October 2026. A single failed section is a smaller job, usually $1,500–$8,000. Length, depth, what sits on top of the pipe and whether the street is involved decide where yours lands.
Those are budgeting ranges compiled by Angeleno Sewer Line Repair from published Los Angeles-area cost data. They are not quotes or company rates, and they say nothing about your line until it has been filmed. What follows explains what each range covers and what pushes a job toward either end.
Typical costs by job type
| Job | Typical LA range | Usually includes | Usually extra |
|---|---|---|---|
| Camera inspection | $175–$800 | Video of the lateral through an existing cleanout | Clearing a blockage, extended locating |
| Hydro jetting the line | $300–$800 | One visit, high-pressure cleaning | Heavy roots or grease push it higher |
| Spot repair, one section | $1,500–$8,000 | Excavating and replacing one failed section on private property | Concrete and driveway restoration, street work, permits |
| Full replacement, open trench | $5,000+ | Excavation, new pipe, backfill, basic soil restoration | Permits and City fees, hardscape, street work |
| Lining (CIPP), per foot | $135–$250/ft | Cleaning prep, liner, reinstatement through existing access | Access pits, a new cleanout, spot repairs the liner cannot bridge |
| Lining, ~50 ft lateral | $6,000–$15,000 | The whole lateral, prep to reinstatement | Street work, permits |
| Pipe bursting, per job | $6,000–$25,000 | Launch and receiving pits, new pipe, reconnection | Street-side pits and hardscape, permits |
| New cleanout | $1,200–$3,900 | Digging to the lateral, fitting, riser, backfill | Less when added during a larger repair |
The spread inside each range is real. Open-trench replacement in particular has a long tail: a short lateral under a lawn sits at the bottom, and a long, deep line under a driveway with street work can pass the top of the range.
What moves the price
A sewer quote is mostly quantity times difficulty. The quantity is footage and depth. The difficulty is everything that makes those feet harder to reach.
| Factor | Why it matters |
|---|---|
| Length of the lateral | Every method is priced partly by the foot. Deep setbacks and corner lots mean longer runs. |
| Depth | Laterals in the City are at least 4 feet deep at the property line. Trenches 5 feet and deeper need shoring, which adds equipment and time. |
| What sits on top | Lawn is cheap to restore. Driveways, patios, stairs and mature trees are not, and they often decide between trenchless and digging. |
| The street section | Work past the property line brings an S-Permit, a City Bonded Sewer Contractor, City inspection, traffic control and a street restoration fee. |
| Pipe material and condition | Collapse and bellies rule lining out. Badly corroded cast iron or broken clay changes which methods are possible. |
| Access | Hillside lots, narrow side yards and rear-of-lot connections limit equipment and slow the work. |
| Groundwater | Near the LA River and in some canyons, a deep trench can meet water and need dewatering. |
| Cleanout | No usable access point means adding one before anything else. |
City fees when the work reaches the street
In the City of Los Angeles the owner is responsible for the whole lateral, including the lower section between the property line and the main. When that section is replaced or repaired, the Bureau of Engineering’s posted fee schedule applies:
- Sewer S-Permit: $273, plus City surcharges of 7% and 3%.
- House connection sewer inspection: $2.84 per linear foot.
- Additional inspection trip: $42 each.
- Street Damage Restoration Fee, when pavement is cut: charged per square foot, set by the street’s classification and how recently it was resurfaced. The posted rates are $8.24 per square foot on a local street and $19.44 on a select street.
These fees are modest next to the construction, which is where most of the street-side cost sits: excavation in the roadway, shoring, traffic control and paving restoration. Those construction costs vary too much by street to publish a reliable range. A bid for street-side work should list the permit, the inspection, the restoration fee and the traffic control as separate lines.
Private-side work needs an LADBS plumbing permit. Its fees are small relative to the job; LADBS publishes the current schedule, and an update to plumbing permit fees was approved in 2026.
The rebate can offset part of it
LA Sanitation runs two rebates for City of Los Angeles sewer service customers: up to $300 toward a camera inspection, and up to $2,500 toward a lateral repair. Both are first come, first served while each year’s funds last. The repair rebate requires a licensed and bonded sewer contractor, a permit finaled by the City, and an itemized invoice, and the program sets deadlines for applying. Plan the paperwork before work starts. More detail is in the LA sewer lateral rebate guide.
How to keep the cost honest
The most expensive mistake is replacing a line that needed one repair, and the second is repairing a line that was failing everywhere. Both come from deciding before the camera has been through the pipe.
Ask for the video, not just the conclusion. Ask where each defect sits, measured from the cleanout, and how deep. Then compare bids on the same scope: the same method, footage, restoration and permits. If one bid proposes lining and another proposes digging, ask each contractor why, with the footage in front of you. A sag holding water is a reason to dig; roots at sound joints usually are not. The replacement service page walks through how the method is chosen, and the estimator puts a range on your own line.

Questions people ask
Why do sewer replacement quotes in LA vary so much?
Because the same words describe very different jobs. Bids differ in method, footage, depth, how much hardscape is included, whether the street section is part of the scope, and which permits are covered. Two quotes are only comparable when they describe the same scope line by line, ideally from the same camera footage.
Is trenchless sewer replacement cheaper than digging?
Sometimes. Lining and bursting cost more per foot of pipe but avoid most of the trench and the restoration that follows it. Under a lawn, a trench can be the cheaper option; under a driveway, mature trees or a long run of hardscape, trenchless often wins. A belly or collapse can take the choice away.
Does homeowners insurance pay for sewer line replacement?
Policies vary, and many exclude wear, deterioration and root damage, which cover most lateral failures. Some insurers sell service line or sewer backup endorsements. Read the exclusions in your own policy and ask the insurer before work begins; do not assume coverage.
