Bill Overview

Analyzed Economic Effects

7 provisions identified: 2 benefits, 1 costs, 4 mixed.

Radiant-floor piping now covered as plumbing

Beginning November 1, 2026, licensed plumbers can install, repair, and maintain piping for residential radiant-floor heating systems. The system must be 100,000 BTUs or less and use piping approved by the current International Mechanical Code.

Easier licensing for veterans and out-of-state plumbers

Beginning November 1, 2026, Oklahoma accepts reciprocity only when there is a written agreement with your state, your license is in good standing, and you meet Oklahoma’s journeyman or residential journeyman requirements. The Board must also review and accept qualified military training and experience for applicants honorably discharged within one year before applying. These steps help speed your path to an Oklahoma license.

Residential plumbers face tighter work limits

Starting November 1, 2026, residential plumbers can work only on one- or two-family homes built as a single structure. The structure can have at most two units and must be at least five feet from any other unit or structure. They cannot work on apartments, motels, or multifamily townhomes. A residential journeyman must be employed and supervised by a licensed plumbing contractor and may not contract for or sell labor and materials. To do commercial or industrial work, a residential journeyman must be employed by a licensed contractor and keep an active apprentice registration.

Annual renewals, continuing education, no license sharing

Beginning November 1, 2026, every plumbing license lasts one year and expires on the last day of your birth month. You can renew within 30 days before or after the due date; journeyman and contractor renewals require approved continuing education. If you renew more than 30 days late, you must pay the renewal fee, an additional fee, and meet continuing education. No late penalty applies if your license expired while you were in military service and you apply within one year after discharge. Apprentice registrations expire one year after issue; you must reregister to keep apprentice status. Licenses are nontransferable; it is unlawful to lend or share your license.

New paths and exam rules for plumbers

Beginning November 1, 2026, you must be at least 18 to take a plumbing exam. For the journeyman exam, you need three years of plumbing experience while employed by a licensed plumbing contractor or during U.S. military service. For the residential journeyman exam, choose one path: two years plus 4,000 verified work hours with a licensed contractor; or an approved associate/vocational program with 1,000 classroom hours plus 3,000 verified work hours with a licensed contractor; or two years of plumbing experience in the U.S. Armed Forces plus 3,000 verified work hours with a licensed contractor. A passing score on any exam is 70%. If you fail, you must wait 30 days to retake. After you pass, the Board issues your license once it certifies your result and you pay required fees.

Higher bar and rules for contractors

Beginning November 1, 2026, plumbing contractors must meet journeyman requirements and have one extra year of experience. Contractors must tell their surety which municipalities they will work in. Contractors may operate as individuals or as firms, partnerships, LLCs, or corporations.

New board runs plumbing license hearings

Beginning November 1, 2026, a designee of the Construction Industries Board chairs plumbing license and discipline hearings. The board includes the members of the State Committee of Plumbing Examiners.
