Oklahoma’s statewide minimum is the **Oklahoma Residential Code**, based on the **2018 IRC** (amended, effective 14 September 2022), set by the Oklahoma Uniform Building Code Commission (OUBCC) and adopted/enforced by local jurisdictions. A **2024 IRC** edition is scheduled to take over on **14 September 2026** — **check with the OUBCC or your local building department for current status** before relying on the 2018-based figures, especially if you’re building close to or after that date. No confirmed Oklahoma-specific stair or guard amendment surfaced — figures follow the [**IRC**](https://www.chippy.tools/building-codes/us/) baseline for whichever edition applies. See the [US stair & guard rules](https://www.chippy.tools/building-codes/us/stairs/stair-and-barrier-requirements/) for the shared figures. ## Adoption status Adopted Current code in force Oklahoma Residential Code — 2018 IRC Next edition — Adoption / transition Statewide minimum code set by OUBCC; 2018 IRC (amended, eff. Sep 14 2022) in effect until Sep 14 2026, when 2024 IRC takes over. Adopted/enforced by local jurisdictions.
