Whole-house repipe permits in Newport Beach, CA
General California guidance last updated October 12, 2026 · Newport Beach data fully re-verified
What plumbing contractors need to know about pulling a whole-house repipe permit in Newport Beach (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.

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.

Code basis
2025 California Building Standards Code (Title 24), which applies to permit applications filed on or after per the California Building Standards Commission. Sections checked against the published code; cities may add local amendments.
California Plumbing Code (Title 24, Part 5) §104.1 — Permits Required: a plumbing permit before installing, altering, repairing, replacing or remodeling a plumbing system; §104.2 (Exempt Work) covers only minor repairs such as stopping leaks and clearing stoppages without replacing or rearranging pipes, valves or fixtures.
California Plumbing Code (Title 24, Part 5) §604.1 — Materials: approved pipe, tube and fittings for water supply; PEX is listed at §604.1.2 and CPVC in residential buildings at §604.1.1.
California Plumbing Code (Title 24, Part 5) §609.4 — Testing: new water piping is pressure-tested before it is covered, which is what the rough inspection verifies (§105.2.1.1 Water Supply System).
California Plumbing Code (Title 24, Part 5) §610.0 — Size of Potable Water Piping: branches and fixture groups are sized by fixture units (§610.4 and Table 610.4), the source of the undersized-branch correction.
California Plumbing Code (Title 24, Part 5) §609.12 — Pipe Insulation; §609.12.3 carries the California Energy Code's hot-water pipe insulation requirements into the plumbing code.
Typically needs a permit
Whole-house repipe itself triggers a permit in nearly every California jurisdiction, Newport Beach included. Newport Beach-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 Newport Beach-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 to repipe my house?
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.
What happens if you don't get a permit for plumbing work?
In California, the building department can stop the work and require a permit after the fact, and pipe covered before inspection may have to be uncovered. Some cities' fee schedules charge extra for work started without a permit, which can double the permit cost. For a licensed contractor, willfully violating permit laws is cause for CSLB discipline (Business and Professions Code §7110). At most home sales, the seller must disclose known unpermitted work (Civil Code §1102.6).
How much is a plumbing permit for a house?
There's no statewide price. Each city or county sets plumbing permit fees in its own fee schedule, so the cost varies by jurisdiction. For the California cities where getPermit has verified local data, that city's page for this job links its published fee schedule, with the source and verification date. Contractor labor and materials are outside this guide.
Can you repipe your own house in California?
Yes, as an owner-builder. Business and Professions Code §7044 exempts a property owner from contractor licensing when they do the work themselves (or with employees paid wages only) and the improvements aren't intended or offered for sale; selling or offering the home for sale within a year of completion creates a rebuttable presumption the work was done for sale. The permit and inspections still apply: under Health and Safety Code §19825, the city or county requires an Owner-Builder Declaration on the permit application, documentation identifying the property owner, and a Notice to Property Owner on the risks that the owner signs before the permit is issued. Hired out, licensed repiping is done by a C-36 (Plumbing) contractor, or a B (General Building) contractor within a larger project, and the contractor typically pulls the permit. getPermit is built for licensed contractors — for an owner-builder permit, contact your city or county building department.
Did repipe permit rules change in 2026?
The permit requirement didn't — a whole-house repipe still needs a plumbing permit. The code edition did: the 2025 California Plumbing Code (Title 24, Part 5) took effect January 1, 2026, per the California Building Standards Commission, and is based on the 2024 Uniform Plumbing Code instead of the 2021 edition. In HCD's rulemaking for that edition, California's own water-supply amendments (Chapter 6) carried forward with only a renamed standard reference (NSF 14 to NSF/ANSI 14) and no intended change in regulatory effect. Local amendments still vary, though a 2025 state law (AB 130) limits new local changes to residential building standards from October 1, 2025 through June 1, 2031 — confirm the edition and any amendments with your city or county building department.
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.
