Code Adoption and Change Process

Code Change Process

Regulatory and Legislative: In June 2009, the Oklahoma Legislature passed a bill (SB 1182) creating the Oklahoma Uniform Building Code Commission (OUBCC) that would be charged to review and recommend building codes (including energy codes) for residential and commercial construction for adoption. Under the revised Oklahoma Administrative Code, Title 748, the codes and standards recommended by the Commission would go before the Oklahoma Legislature. Should the Legislature not act to disapprove the recommendations, they will be submitted to the Secretary of State (SOS) for filing. Local governments would be allowed to adopt more efficient standards than those recommended by the Commission. The OUBCC has the discretion to choose the method of code adoption that is found to be best and most appropriate. Typically the commission will select and utilize a technical committee to research and review options for code updates and consider the technical committee’s recommended course of action. The public comment phase occurs during the technical committee’s deliberations. The commission may then commence APA rulemaking to adopt the appropriate code updates.
