Sewer line replacement permits in San Jose, CA
General California guidance last updated May 22, 2026 · San Jose data verified May 22, 2026
What plumbing contractors need to know about pulling a sewer line replacement permit in San Jose (Santa Clara 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.
San Jose accepts submittal through the SJPermits.org (San José Online Permit Center) and has adopted the 2025 California Building Standards 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.

Typically needs a permit
Sewer line replacement itself triggers a permit in nearly every California jurisdiction, San Jose included. San Jose-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 San Jose-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.
