What plumbing contractors need to know about pulling a sewer line replacement permit in Pleasanton (Alameda 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.

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.

Typically needs a permit
Sewer line replacement itself triggers a permit in nearly every California jurisdiction, Pleasanton included. Pleasanton-specific variations are confirmed with the issuing department above.
Usually doesn't (general norm)
- Clearing a drain stoppage with a snake or hydro-jet
- Repairing a single broken section of accessible pipe with the same material
- Camera-inspecting an existing lateral for diagnostics
Documents & plans generally required
- Plumbing permit application (plus encroachment / right-of-way permit if work crosses the property line)
- Contractor license and city business registration
- Site/plot plan showing the lateral route, depth, slope, and tie-in point at the main
- Pipe material, diameter, and class (ABS, PVC SDR-35, lined CIPP, etc.)
- Cleanout locations — at the building, at the property line, and at directional changes per code
- Backwater-valve detail where required by ordinance or where a fixture is below the next upstream manhole rim
- Trenchless method detail for pipe-bursting or CIPP (bursting head, host-pipe condition, liner thickness, cure method)
- Bedding and backfill specs
Common reasons sewer line replacement applications get bounced
Code-rooted patterns across California — not a Pleasanton-specific rejection rate.
- Slope insufficient — CPC minimums are typically 1/4-inch per foot for 3-inch and smaller, 1/8-inch per foot for 4-inch and up
- Missing cleanout at required locations (base of stack, property line, every 100 feet, and at direction changes)
- No backwater valve where the ordinance requires one — common in flood-prone or older sewered areas
- Pipe class not appropriate for cover depth or loading conditions
- Tie-in at the city main not coordinated with public works / wastewater utility
- Trenchless application missing host-pipe condition or liner-thickness calculation
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Pre-cover inspection with the new pipe in place, sloped, supported, and air/pressure-tested
- 2Right-of-way / utility inspection at the connection to the city main (when applicable)
- 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.
