Direct Answer
Oklahoma adopts and amends the International Fire Code (IFC) through the Oklahoma Uniform Building Code Commission (OUBCC). The 2024 IFC with Oklahoma amendments has been in effect since September 14, 2026; the 2018 IFC was superseded on that date (OUBCC adoption records).

Who This Applies To
All commercial building and fire code projects in Oklahoma, including schools, government facilities and commercial buildings — except one- and two-family dwellings and townhouses governed by the IRC.
What Oklahoma Requires
Oklahoma adopts the IFC with Oklahoma-specific amendments. The base model code alone does not control — the Oklahoma-adopted amendments must be reviewed for every project. The State Fire Marshal enforces the code for state-owned/occupied property and is the default AHJ statewide unless a local AHJ agreement is active.
Plain-English Explanation
Oklahoma doesn't write its own fire code from scratch. It adopts the International Fire Code and then modifies it with Oklahoma-specific amendments. The 2024 edition has been in effect since September 14, 2026 (the 2018 edition was superseded that day). For any project you must look at both the model code and the Oklahoma amendments — and confirm which AHJ (State Fire Marshal or local) has jurisdiction.
Applicable Code / Standard
International Fire Code (IFC), as amended by the OUBCC
Oklahoma Amendments
Yes — Oklahoma amendments apply and must be reviewed alongside the base model code.
Who Enforces It?
Oklahoma State Fire Marshal (statewide default and for state property); local city/town or county AHJs with active agreements.
AHJ Considerations
Confirm whether your project is under the State Fire Marshal or a local AHJ before design. Whether earlier-edition submittals are still accepted depends on the reviewing authority; confirm with the State Fire Marshal or your local AHJ, since local AHJs set their own transition timelines.
Facility Owner Checklist
- Confirm the applicable AHJ (State Fire Marshal or local)
- Verify the effective code edition for your permit date
- Review Oklahoma amendments, not just the base IFC
- Confirm plan-review transition policy with your AHJ
- Engage a licensed Oklahoma contractor (ODOL)
Common Compliance Problems
- Assuming the base model code controls without checking Oklahoma amendments
- Applying the wrong edition for the permit date
- Assuming the State Fire Marshal grace period applies to a local AHJ
- Using an unlicensed contractor
