Sewer Line Repair in North Hollywood — Built for the Pipes That Actually Run Here

If you manage or rent in one of North Hollywood’s many mid-century apartment buildings, you already know that plumbing problems don’t ask for permission. The dense stretch of multi-unit housing between Lankershim and Laurel Canyon is packed with buildings constructed in the 1960s and 1970s — and most of them are still running on the original cast iron and clay sewer laterals. Those pipes are now over 50 years old, and they show it. EZ Plumbing has been handling sewer line repair in North Hollywood since 1989, and we understand exactly what fails here, why it fails, and how to fix it right the first time.

Sewer line problems in North Hollywood tend to follow predictable patterns. Shared lateral lines serving four, six, or eight units develop grease buildup and root intrusion over decades of heavy use. Galvanized pipe — still found in older buildings throughout the NoHo Arts District and surrounding streets — corrodes from the inside out, narrowing the flow until backups become a monthly headache for tenants and a liability nightmare for property managers. When one unit backs up, it rarely stays that way. In dense multi-unit buildings, a failed sewer lateral affects everyone fast.

We use camera inspection to locate the exact problem before we dig or recommend any repair. That means no guesswork, no upselling work that isn’t needed, and a clear explanation you can share with your tenants or your HOA. Whether it’s a partial collapse, a cracked clay pipe, or years of compacted grease, our team gives you honest options — traditional excavation or trenchless methods depending on the situation — and pricing that makes sense for both homeowners and property managers watching a budget.

Why North Hollywood’s Aging Apartment Stock Creates Unique Sewer Challenges

The construction boom that built much of residential North Hollywood between 1955 and 1980 used materials that were standard at the time but were never designed to last indefinitely. Clay sewer laterals were the norm, and they crack, shift, and separate as the ground moves over decades. Cast iron drain lines inside buildings corrode at joints and low points. And because these buildings were designed with minimal clearance under slabs and between units, accessing failed lines can be genuinely complicated without the right equipment and experience.

We also see a specific problem on the commercial corridors near Burbank Boulevard and Vineland Avenue: restaurant and food service grease that finds its way into shared residential laterals. When a mixed-use building has a restaurant on the ground floor and apartments above, the sewer lateral takes on grease loads it was never sized to handle. Sewer line repair in North Hollywood for these properties requires a different approach than a standard residential job, and our team has the experience to handle both.

Frequently Asked Questions — Sewer Line Repair in North Hollywood

Our apartment building has six units and the sewer backs up every few months. Is this a shared lateral problem?

Almost certainly, yes. In North Hollywood’s older multi-unit buildings, a single shared lateral handles all the waste from every unit. When that line is partially blocked by grease, roots, or pipe deterioration, frequent backups across multiple units are the typical result. A camera inspection will show us exactly where the restriction is — it’s usually not in any one tenant’s unit, but in the shared line running toward the city main. We can then assess whether hydro-jetting will provide lasting relief or whether a section of the lateral needs repair or lining.

My building has galvanized pipes. Does that affect sewer line repair costs or methods?

Galvanized pipe is primarily a water supply line material, but many North Hollywood buildings from the 1960s and 70s have it throughout. If the interior drain lines connecting to your sewer lateral are also aging cast iron or even some early galvanized installations, they may need to be addressed as part of a complete repair — otherwise you fix the lateral and still deal with interior drain failures. We inspect the full drain system and give you an honest picture of what’s causing your problem and what will actually solve it long-term.

Can sewer line repairs be done without tearing up the tenant parking area or courtyard?

In many cases, yes. Trenchless repair methods — including cured-in-place pipe lining (CIPP) and pipe bursting — allow us to rehabilitate or replace a failed sewer lateral with minimal excavation. These methods work well in the tight lot configurations common in North Hollywood apartments, where parking, landscaping, and neighboring property lines leave little room for a traditional open trench. After inspecting your line, we’ll tell you honestly whether trenchless is appropriate for your specific failure or whether excavation is the safer call.

Who is responsible for sewer line repair — the property owner or the City of Los Angeles?

This is one of the most common questions we hear from North Hollywood property managers. In Los Angeles, the property owner is responsible for the sewer lateral from the building all the way to the connection point at the city main — that’s typically the full length running under your property and sometimes under the sidewalk or parkway. The city maintains the main sewer line in the street itself. If your lateral fails anywhere before that connection point, the repair cost falls to you. We can help you identify exactly where the failure is located so you know what’s yours to fix and what to report to the city if needed.
