Sometimes, depending on the project

Before altering, replacing or rearranging plumbing or gas systems, or installing any new or used plumbing equipment or appliance.

Quick answer

Oklahoma City requires a plumbing permit for essentially all plumbing and gas work, including replacing a water heater or moving a fixture, and the ordinance applies regardless of equipment size or type. The exemption is narrow: maintenance and repair that does not alter or rearrange the plumbing installation, so a straight leak repair or washer change is outside the permit. Gas services and gas piping systems always need a permit. Permits are issued by the Development Services Department only through a state-licensed, city-registered plumbing contractor.

Who is pulling this permit?

Hire it out

Before you sign, ask the contractor:

  • Who pulls the permit, you or me, and is the permit fee included in the bid?
  • Which inspections will this job need, and who meets the inspector on site?
  • Is your contractor license active in this locality, and under which business name?

How to apply in Oklahoma City

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.

  1. 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).
  2. 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).
  3. 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).
  4. 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).
  5. 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).
  6. 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).
  7. 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 Oklahoma City permit portal or by phone at (405) 297-2525.

Can a homeowner pull a plumbing permit themselves in Oklahoma City?
Under Oklahoma law (11 O.S. 43-109.2(B); 59 O.S. 1692(B)(3), 1017(6), 1151.17(B), 1850.10(A) and (B)(1), 1693(A)): Oklahoma does not license general or residential contractors at the state level, which is unusual and was verified by reading the whole of Title 59: the state licenses plumbing (59 O.S. 1001 et seq.), electrical (59 O.S. 1680 through 1699), mechanical (59 O.S. 1850.1 et seq.), roofing by registration (59 O.S. 1151.1 et seq.) and building and construction inspectors (59 O.S. 1031 through 1046), and no chapter licenses a general contractor. A homeowner may pull their own permit and do their own work. 11 O.S. 43-109.2(B) exempts a person doing construction or remodeling on their own single-family or duplex structure on their own property from the insurance verification a permit office must otherwise obtain before issuing a residential building permit, and it applies even when the structure is a rental, but the exemption disappears the moment a general contractor or subcontractor performs the work and pulls the permit. The trade acts carry matching self-work exemptions: no state license is needed to do electrical work on your own property or residence (59 O.S. 1692(B)(3)) or plumbing work on your own property of residence (59 O.S. 1017(6)), and a person roofing their own property is exempt from roofing registration though they must still give the permit office the registration number of any roofing subcontractor (59 O.S. 1151.17(B)). Every one of those is a licensing exemption only, expressly subject to local ordinances in the electrical case, and none of them waives the city permit; 59 O.S. 1693(A) still bars electrical work in a city or town without a permit first being obtained. Mechanical work is the sharp exception: the property-owner exemption in 59 O.S. 1850.10(B)(1) reaches only minor repair, and 59 O.S. 1850.10(A) requires a mechanical or plumbing licensee to install, replace or repair gas piping, floor furnaces, wall heaters or radiant-floor heating with no owner carve-out. Oklahoma has no statewide owner-builder disclosure form and no sale restriction comparable to Florida's one-year rule; the term owner-builder appears nowhere in Title 11 or Title 59.
