| Energy | IECC 2015 | one of the oldest energy-code floors in this dataset | " |
Adoption model & precedence
- OUBCC sets the statewide minimum; jurisdictions "have the ability to adopt these minimum codes" and may adopt more restrictive codes — meaning many metros likely exceed the state floor.
- Pipeline: code-change proposals for the 2027 NEC and commercial energy code are being accepted through 2026-06-30 — OUBCC is actively working the next cycle.
- AHJ = local jurisdiction, applying at least the state minimum (often more).
Major cities / counties
| Jurisdiction | County | Notes | Building dept. |
|---|
| Oklahoma City | Oklahoma | publishes its own adopted safety codes list — confirm current OKC-specific editions | okc.gov |
| Tulsa | Tulsa | confirm local adoption vs. state floor | cityoftulsa.org |
| Norman | Cleveland | confirm local adoption vs. state floor | normanok.gov |
AHJ fallback (when local adoption is unverified)
- State baseline (minimum, likely dated vs. local reality): 2018 IBC/IRC/IPC/IMC, NEC 2017, IECC 2015.
- Action: confirm the specific city's adopted editions — OK explicitly permits (and many metros exercise) more current/restrictive local adoption.
Change log
