Cal. Health and Safety Code § 34321

It is declared to be the policy of the State that each authority shall manage and operate its housing projects in an efficient manner so as to enable it to fix the rentals for dwelling accommodations at the lowest possible rates consistent with its providing decent, safe, and sanitary dwelling accommodations, and that no housing authority shall construct or operate any such project for profit, or as a source of revenue to the city or the county. To this end an authority shall fix the rentals for dwellings in its projects at no higher rates than it finds necessary to produce revenue which, together with all other available money, income, and receipts of the authority, will be sufficient for all of the following: (a) To pay, when due, the principal and interest on its bonds. (b) To meet the cost of, and to provide for, maintaining and operating the projects, including the cost of any insurance, and the administrative expenses of the authority. (c) During not less than the six years immediately succeeding its issuance of any bonds, to create a reserve sufficient to meet the largest principal and interest payments which will be due on such bonds in any one year thereafter and to maintain the reserve. However, this subdivision shall not be construed to prevent an authority from utilizing any financial aid from the federal government to the maximum extent available. This section shall not apply to any person, individual, firm, partnership, company, association, joint stock association or corporation other than a public entity having an interest in any housing project owned in part or constructed or operated by one or more authorities.
