Quick answer
Riverside County exempts only genuinely minor plumbing work: stopping a leak, clearing a stoppage, repairing leaks in pipes, valves or fixtures, removing and reinstalling a water closet, and faucet or toilet repair and replacement. The county's ordinance draws the line explicitly, stating that once a defective pipe has to be removed and replaced with new material the job counts as new work and a permit must be obtained. Water heater replacement and single-family re-pipes are on the county's mandatory self-certification list, filed through the public portal and signed off by a licensed contractor. This applies to unincorporated Riverside County; the county's incorporated cities run their own building departments.

How to apply in Riverside County
In Riverside County, you apply for a residential plumbing permit at your local building department by filing an application that describes the scope of work and site, along with construction documents, before any regulated plumbing installation, alteration, or repair begins. Minor repairs that do not touch piping or fixtures are generally exempt, and once issued the permit only stays valid if work is started within its time limit.
What most plumbing permit applications include:
- For Riverside County, a permit is required before any owner or authorized agent constructs, alters, repairs, removes, converts, or replaces a plumbing system regulated by the code (IRC R105.1).
- For Riverside County, the application must identify and describe the work, describe the site, state the intended use and occupancy, and be signed by the applicant or an authorized agent (IRC R105.3).
- Two or more sets of construction documents must accompany the application, drawn with enough clarity to show the location, nature, and extent of the proposed plumbing work and how it will conform to code (IRC R106.1, R106.1.1).
- Minor plumbing repairs, such as clearing a stoppage or removing and resetting a water closet without rearranging pipes or fixtures, are exempt from permit (IRC R105.2).
- Once issued, a permit is only valid for a limited window, commonly 180 days, and becomes invalid if the work is not started or is abandoned within that time, though extensions can be requested (IRC R105.3.2, R105.5).

Inspections and closing out your permit
In Riverside County, plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.
- In Riverside County: piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
- In Riverside County: rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
- In Riverside County: rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
- In Riverside County: the water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
- In Riverside County: the framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
- In Riverside County: at the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).
- In Riverside County: final inspection is made after all work required by the permit is complete, and includes confirming backflow protection, such as vacuum breakers on hose bibbs, is installed (IRC R109.1.6, P2902.4.3).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Riverside County permit portal or by phone at 951-955-1800.

- Where do you apply for a plumbing permit in Riverside County?
- You can apply through the Riverside County permit portal or contact the Riverside County Building and Safety Department (Transportation and Land Management Agency) directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Riverside County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner from contractor licensing under section 7044 when they personally perform all the work on their own property, or any work they do not perform themselves is done by their own employees paid only wages, and none of the improvements are intended or offered for sale. It also exempts an owner who directly contracts with licensed contractors for each trade, as long as no more than four of the single-family residential structures involved are intended or offered for sale in a calendar year; this route does not apply if the owner instead contracts with a general contractor for the construction. A homeowner may also improve their own principal residence without a license, as long as the work is done before any sale, they have actually resided there for the 12 months before completion, and they have not used this exemption on more than two structures more than once in any three-year period. Selling a self-built structure within one year of completion creates a rebuttable presumption that it was built for sale, which defeats the exemption, and selling five or more structures within a year makes that presumption conclusive. Separately, every city or county that requires a permit must also require the applicant to file a signed statement giving their contractor license number or the basis of their claimed exemption; a false or missing statement carries a civil penalty of up to $500. Confirm how Riverside County applies this before you apply.
