Summary

Oklahoma City requires a permit for nearly all plumbing and fuel-gas work under Municipal Code Section 42-36, issued only to a state-licensed, City-registered plumbing contractor working in the property owner's name. The City has adopted the 2018 International Plumbing Code, as locally amended, to set the technical standard. Permits aren't required for maintenance or repairs that don't alter or rearrange the plumbing installation, but working without a required permit is a Class "a" offense.

No permit shall be issued under this article except in the name of the building/property owner through a State licensed, City registered plumbing contractor by whom such plumbing work is to be performed. Permits shall be required for maintenance work or for repair work where plumbing or gas systems are altered, replaced or rearranged. Prior to commencement of any plumbing installation the plumbing contractor shall contact the Development Services Department and obtain a permit. The permit shall be numbered, listing the name of the contractor, job address, building permit number, and scope of the plumbing installation proposed. The permit covers only that work listed thereon. Any additions or changes shall be reported to the Development Services Department and additional inspection fees may be assessed prior to requesting final inspection. Plumbing permits are transferable upon approval by the Development Services Department.

Violations & Fines

Section 42-25 makes any violation of the plumbing chapter, including working without the Section 42-36 permit, a Class "a" offense for each violation, escalating to a Class "b" offense on a second or subsequent proven conviction. Section 42-41 separately ties starting work before securing the permit to that same Section 42-25 penalty. An owner who fails to promptly correct a defective plumbing system after notice is also guilty under Section 42-25(b), subject to the identical penalty schedule.

Frequently Asked Questions

Can a homeowner pull their own plumbing permit in Oklahoma City?
No. Section 42-36 says no permit may be issued except in the property owner's name through a State-licensed, City-registered plumbing contractor performing the work, so the contractor, not the homeowner, must obtain it before work begins.
What plumbing code does Oklahoma City enforce?
The City adopted the 2018 Edition of the International Plumbing Code under Section 42-2, as amended by City Council resolution signed by the Mayor on February 27, 2024, and it governs all permitted plumbing and gas work citywide.
Do I need a permit for a simple repair?
Not if the work doesn't alter or rearrange the plumbing installation. Section 42-37 exempts maintenance or repair work from the permit requirement as long as nothing is altered or rearranged; anything beyond that, including replacing fixtures, needs a Section 42-36 permit.
What happens if I start plumbing work before getting a permit?
Section 42-41 requires securing the permit and paying the inspection fee before work begins, and starting early triggers the Section 42-25 penalty: a Class 'a' offense for each violation, rising to a Class 'b' offense on a second proven conviction.
