Cal. Health and Safety Code § 101839

A transfer of maintenance, operation, and management or ownership to the hospital authority may be made with or without the payment of a purchase price by the hospital authority and otherwise upon the terms and conditions that the parties may mutually agree, which terms and conditions shall include those found necessary by the board of supervisors to ensure that the transfer will constitute an ongoing material benefit to the county and its residents. In the event of such a transfer: (a) A transfer of the maintenance, operation, and management to the hospital authority shall not be construed as empowering the hospital authority to transfer any ownership interest of the county in General Hospital and the Family Care Centers except as otherwise approved by the board of supervisors. (b) The board of supervisors shall retain control over the use of General Hospital and the Family Care Centers physical plant and facilities except as otherwise specifically provided for in lawful agreements entered into by the board of supervisors. Any lease agreement or other agreement between the county and the hospital authority shall provide that county premises shall not be sublet without the approval of the board of supervisors.
