    Local jurisdictions are responsible for enforcing any locally adopted codes. The Oklahoma State Department of Central Services administers construction and maintenance programs for state-owned and -leased buildings.

    Compliance Process

    For state-owned buildings, the Oklahoma Office of Central Services, Construction Properties Division, monitors the construction process for compliance with the relevant construction codes.
