Your sewer lateral runs from the house to the public main, often under the parkway, sidewalk, and street. In most local jurisdictions, the owner is responsible for the entire lateral. Trenchless repair can often renew the street-side section from your property, but it can require additional permits. In Marina del Rey, LA County Public Works says the owner is responsible for the entire lateral, including the portion under the street.
Many owners assume the city or county is responsible once the pipe leaves their yard. In most local jurisdictions, that's not the case: the owner maintains the lateral all the way to its connection with the public main, including the part under the parkway, sidewalk, and street. That's often where the oldest pipe and the most root damage are. This page is part of our complete guide to trenchless sewer repair in Marina del Rey.
Trenchless Lateral-to-Main Repair: A lateral-to-main repair renews the section of a private sewer lateral between the property line and the public sewer main, often under the parkway and street.
Repairing it by excavation means cutting the sidewalk or street, traffic control, and restoration to public standards. Trenchless methods can often renew that section from access on your side, lining or bursting through to the connection at the main.
In Marina del Rey, LA County Public Works says the owner is responsible for the entire lateral, including the portion under the street. County Code holds Marina del Rey owners responsible for the full lateral, including the right-of-way portion.
We record the lateral all the way to the connection.
We verify what your jurisdiction requires for street-side work.
Lining or bursting reaches the main without an open trench in the road.
We verify the connection at the main and document it.
Camera first, always. Every recommendation starts with a recorded inspection you can watch yourself, and a flat-rate price you approve before we start.
LA County Public Works is explicit about this: the property owner is responsible for the entire length of the sewer lateral, including the portion under the street and street landscaping, under County Code 20.24.080. For Marina del Rey buildings, that street-side section can be long, and it's where problems sometimes show up first, when County crews inspecting the public main find roots or debris at a private connection. We camera the whole lateral to the main, confirm what County permitting the street section needs, and renew it from the property side whenever the pipe allows.
Marina del Rey's buildings are younger than Mar Vista's bungalows, but many are now fifty-plus years old, and their original cast-iron and early plastic drain lines are showing it. Shared laterals and building drains mean a slow line in one unit is often a symptom of a problem further down the system. If the repair can be scheduled rather than rushed, we'll help you plan it around residents and budget cycles.

Sewer repairs in Marina del Rey run through LA County Building & Safety, which serves the County's unincorporated communities. Permitted work protects owners and associations at sale, refinance, or insurance review; unpermitted repairs tend to resurface later. We'll flag up front if any part of the work is in the street and needs additional County permits.
Example scenario below is illustrative, based on common situations we see. Details vary by property; not a specific customer.
A Marina del Rey building receives notice that roots in its lateral are affecting the County main.
We camera the lateral to the main, cut the roots, and line the street-side section from the building's cleanout.
The connection is sealed, the notice is resolved with documentation, and the street stays uncut.

The Bottom Line
The street section of your lateral is usually your responsibility, and often the worst part of the line. Trenchless methods can renew it from your side, with the right permits in place.
In most local jurisdictions, yes: the owner maintains the lateral to its connection with the main. We’ll confirm the rules for your address. In the City of LA, the owner’s responsibility runs from the building all the way to the connection at the public main, including the section under the parkway or street. See LASAN’s sewer lateral information page.
Often, yes. The camera tells us whether the connection and the street section are suitable for lining or need bursting. For unincorporated Marina del Rey, LA County Public Works applies the same principle: the private lateral is the owner’s to maintain, including the segment in the public right-of-way. See the County’s private lateral maintenance page.
The goal of trenchless is to avoid it. If a connection issue requires excavation at the main, we’ll tell you before any work is scheduled. Work in the right-of-way triggers an additional permit and, sometimes, traffic control. We include those items in the flat-rate quote so nothing is a surprise.
It can. Work in the public right-of-way often requires permitting beyond the standard plumbing permit, and we include that in the plan. For lining a lateral all the way to the main, we launch from a cleanout and reinstate any branch connections after the liner cures. See our trenchless sewer repair overview.
LA County Public Works states the owner is responsible for the entire lateral, including the portion under the street, under County Code 20.24.080. In Marina del Rey (unincorporated County), owner responsibility runs to the main under County rules. See the County’s private lateral page.
