Sewer line replacement permits in Long Beach, CA

General California guidance last updated May 22, 2026 · Long Beach data verified August 10, 2026

What plumbing contractors need to know about pulling a sewer line replacement permit in Long Beach (Los Angeles County).

Short answer

In California, replacing a sewer lateral or building drain needs a plumbing permit, pulled by a licensed C-36 (Plumbing) or C-42 (Sanitation) contractor under the California Plumbing Code (Title 24, Part 5). The work often coordinates with the city's wastewater utility, and an encroachment / right-of-way permit is generally required when work extends into the public right-of-way.

Long Beach accepts submittal through the LB Services — Permitting and Licensing and has adopted the 2025 California Building Standards Code (with the Long Beach Municipal Code). Fee details and sources are below.

The general picture in California

A sewer-line replacement covers the building's drain from the foundation out to the city main (or septic). The permit covers pipe material (typically ABS, PVC SDR-35, or cast iron for certain conditions), slope, bedding, cleanouts, backwater valve (required by ordinance in many California cities on lateral replacements), and connection to the city main. Trenchless methods — pipe bursting and cured-in-place pipe (CIPP) lining — are common and have their own submittal requirements. Work in the public right-of-way (between the property line and the main) often requires a separate encroachment permit from public works on top of the building permit.

Common reasons sewer line replacement applications get bounced

Code-rooted patterns across California — not a Long Beach-specific rejection rate.

The inspection sequence

A typical order — the number of stops and exact sequence vary by jurisdiction and scope.

  1. 1Pre-cover inspection with the new pipe in place, sloped, supported, and air/pressure-tested
  2. 2Right-of-way / utility inspection at the connection to the city main (when applicable)
  3. 3Final inspection with backfill, restoration, and any required surface work complete

Licensing — who can pull it

Sewer-line replacement in California is generally performed by a C-36 (Plumbing) or C-42 (Sanitation) licensed contractor; a B (General Building) contractor may pull within a larger project under CSLB rules. The licensed contractor doing the work typically pulls the permit; work in the public right-of-way may also require a separate encroachment-permit filing.

Frequently asked questions

Do I need a permit to replace a sewer lateral in California?

Yes — replacing the building lateral (from the foundation to the city main) is permitted plumbing work in every California jurisdiction. Work in the public right-of-way usually requires an additional encroachment / right-of-way permit from the city's public works department.

What is a backwater valve and when is it required?

A backwater valve prevents sewer backflow into the building during a main-line surcharge. The California Plumbing Code requires one when any fixture is below the next upstream manhole rim; many California cities require one on every lateral replacement regardless. Check the local ordinance.

Do trenchless methods (pipe bursting, CIPP) need a permit?

Yes — trenchless methods need the same plumbing permit, plus submittal details specific to the method: host-pipe condition, bursting head size or liner thickness, and cure procedure. Inspection sequencing may differ — some jurisdictions verify the lined pipe with a post-install camera inspection.

Who connects to the city main?

The contractor performs the tie-in, but the city's public works or wastewater utility typically inspects (or requires advance notice of) the connection. Encroachment permits cover the work in the right-of-way; some cities require their own crew to perform the actual tap.
