Okla. Admin. Code § 310:662-7-1
A certified/accredited agency shall not be subject to routine licensure inspections by the Department. Branch offices of certified/accredited agencies whose parent agency is not located in the State of Oklahoma shall not be considered to be certified/accredited, neither shall they be exempt from routine licensure inspections. The Department may inspect any agency at any time in order to determine compliance with the provisions of the Act or this Chapter. These inspections may be routine as in the case of a non-certified/accredited agency or based on a complaint received by the Department. The right of inspection shall also extend over any home care agency the Department has reason to believe is advertising or operating a home care service without a license.
