Gov. Code, § 50570

Notwithstanding the provisions of Sections 54222 and 54223, a local agency, or any department, agency or authority thereof may lease, sell or grant or otherwise transfer any real property, including air rights owned, held or controlled by it and found to be in excess of foreseeable needs under this article, to any housing corporation, limited dividend corporation or nonprofit corporation, upon such terms and conditions as any other provisions of law notwithstanding the local agency may deem to be best suited to the development of the parcel for housing available to persons and families of low or moderate income at affordable housing cost, as defined by Section 50052.5 of the Health and Safety Code. The deed or other instrument of conveyance shall provide that whenever the ownership of the land or the mortgagor corporation is no longer composed of a majority of the nonprofit or limited dividend sponsors, title to the land shall revert to the local agency. The deed or other instrument of conveyance shall also contain a recital that the grantor local agency or department, agency or authority thereof has made the finding required by this section and such recital shall be conclusive in favor of purchasers or encumbrancers for value.
