General California guidance last updated May 22, 2026 · Anaheim data fully re-verified
What plumbing contractors need to know about pulling a whole-house repipe permit in Anaheim (Orange County).
Short answer
In California, a whole-house repipe needs a plumbing permit, pulled by a licensed C-36 contractor under the California Plumbing Code (Title 24, Part 5). The permit covers replacing existing supply (and sometimes drain/waste/vent) piping; common drivers include failing galvanized or polybutylene supply, slab leaks, low-pressure complaints, and pinhole leaks in copper.
Anaheim accepts submittal through the Anaheim Next (Accela) and has adopted the 2025 California Building Standards Code (with Anaheim amendments). Fee details and sources are below.

The general picture in California
A repipe replaces the hot/cold supply distribution throughout a structure — most commonly converting galvanized or polybutylene to PEX or copper. The permit covers pipe material, sizing, routing, fastening, insulation, manifold or trunk-and-branch layout, and pressure testing. Drain/waste/vent repipes add slope, venting, and cleanout requirements. Drywall and finish repairs are out of scope of the plumbing permit but may require their own permits if structural framing is altered.

Typically needs a permit
Whole-house repipe itself triggers a permit in nearly every California jurisdiction, Anaheim included. Anaheim-specific variations are confirmed with the issuing department above.
Usually doesn't (general norm)
- Replacing an exposed section of supply pipe with the same material and routing (repair)
- Replacing a fixture supply line, angle stop, or stop valve
- Tightening or replacing a single fitting on existing pipe
Documents & plans generally required
- Plumbing permit application
- Contractor license and city business registration
- Pipe material, size, and manufacturer (PEX-A vs. PEX-B, copper type, fitting system)
- Routing plan — trunk-and-branch vs. manifold, with pipe sizes per fixture group
- Pressure-test procedure and the test pressure to be held
- Penetration and fire-stopping details where lines pass through rated assemblies
- Listing/approval for any non-traditional pipe (specific PEX listings, fitting systems)
Common reasons whole-house repipe applications get bounced
Code-rooted patterns across California — not a Anaheim-specific rejection rate.
- Pipe sizing not matching the fixture-unit load (undersized branches feeding multiple fixtures)
- Pipe material or fitting system not listed for potable water use in California
- No pressure-test procedure or insufficient hold pressure shown
- Missing penetration / fire-stopping detail at rated walls and floor assemblies
- Hot-water line insulation not specified per Title 24 Part 6
- DWV scope missing slope, cleanouts, or venting where the repipe includes drainage
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Rough/cover inspection with new piping exposed, pressure-tested, and supported
- 2Insulation inspection for Title 24 hot-water-line insulation where applicable
- 3Final inspection with fixtures reconnected, pressure restored, and the system tested
Licensing — who can pull it
Repipes in California are performed by a C-36 (Plumbing) 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.

Frequently asked questions
Do I need a permit for a whole-house repipe in California?
Yes — replacing supply (and/or DWV) piping throughout a structure is permitted plumbing work in every California jurisdiction. The permit covers material, sizing, routing, and pressure testing; the inspector typically signs off at rough (pre-cover) and at final.
Is PEX allowed throughout California?
Yes — PEX has been approved statewide for potable water under the California Plumbing Code for over a decade. Some jurisdictions still require specific listings or limit certain fitting types; the listing should be shown on the permit submittal.
Do I need a separate permit for drywall repair?
The plumbing permit covers the pipe work only. Drywall and finish repair are typically follow-up work and don't require a separate permit unless structural framing is altered. Inspectors will require pipe access (open walls or strategic cuts) at the rough inspection.
Can a repipe be done in an occupied home?
Generally yes — most residential repipes are done with the occupants in place, with water shut off for short periods. The permit doesn't restrict occupancy; sequencing is a contractor/owner decision.
