Cal. Health & Saf. Code § 51251
Notwithstanding any other provision of law, the Department of General Services, any other state agency or officer authorized by law to convey real property of the state, and any local public entity may, in his or her or its discretion, from time to time sell, lease for a term not exceeding 99 years, grant, or convey to the agency or to a housing sponsor designated by the agency any real property and appurtenances thereto or any interest therein owned by the state or local public entity which the agency shall certify as necessary for its purposes. The certification of need shall be evidenced by a formal request from the executive director of the agency. Any sale, lease, grant, or conveyance pursuant to this section shall be made with or without consideration and upon terms and conditions which may be mutually agreed upon by the state or local public entity and the agency. However, before any sale, lease, grant, or conveyance pursuant to this section is made at less than fair market value, the agency shall make a finding that the difference between the consideration required and fair market value will inure primarily to the benefit of persons and families of low or moderate income living in a housing development or a residential structure.
