Plumbing Permit in Eugene, Oregon
Permit required
Yes, a permit is required
Before adding, moving, removing or capping off any plumbing fixture, before replacing a water heater, before running water, sanitary or storm service piping, and for the plumbing serving projects that are themselves exempt from a building permit.

Quick answer
Eugene issues plumbing permits directly through eBuild and states that a separate plumbing permit is required even for work exempt from a building permit. Alterations to an existing house are charged per fixture at $29.20, new construction is charged by bathroom count, and even a like-for-like water heater swap has its own $72.00 permit covering one inspection. Plan review is not part of a routine residential job: the application lists the triggers, which are medical gas and vacuum systems, chemical drainage, wastewater pretreatment, vacuum drainage, reclaimed wastewater, commercial booster pumps, water service lines of 2 inches or larger, multi-purpose fire sprinkler systems and grease processing equipment.

What a plumbing permit costs in Eugene
How to apply in Eugene
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:
- 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).
- 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
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.
- 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).
- 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).
- 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).
- 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).
- 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).
- 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).
- 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 Eugene permit portal or by phone at 541-682-5086.

- How long does a plumbing permit take in Eugene?
- Eugene states that intake staff review a trade permit application submitted through eBuild within 3 business days, after which fees can be paid online and "Once the fees have been paid, the permit will automatically be issued.". Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a plumbing permit in Eugene?
- You can apply through the Eugene permit portal or contact the City of Eugene Building and Permit Services, Planning and Development Department directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Eugene?
- Under Oregon law (ORS 701.010(7); ORS 701.325(1), (2), (3)): A homeowner may pull the permit and do the work. ORS 701.010(7) exempts from Construction Contractors Board licensing a person performing work on property that person owns, or on that person's own residence whether or not they own it, so no CCB license is needed to act as your own builder. That exemption does not cover someone working in the pursuit of an independent business with intent to offer the structure for sale. Oregon does require a signed disclosure at the counter: ORS 701.325(1) makes every city, county, or state permit office collect a written statement signed by the applicant, and an applicant claiming a licensing exemption must state the basis for it. ORS 701.325(2) requires the office to give the applicant the Information Notice to Property Owners About Construction Responsibilities and withhold the residential building permit until the applicant signs a statement, one option of which is that they are performing work on property they own or a residence they live in or will live in, and that any contractors they hire will be CCB licensed and properly endorsed. The Information Notice itself is a CCB rule form under ORS 701.325(3) covering payroll tax, workers' compensation, and liability and property damage insurance responsibilities. Confirm how Eugene applies this before you apply.
