California Code, Health and Safety Code - HSC § 33411.3

If all or any portion of a redevelopment project is developed with low- or moderate-income housing units and low- or moderate-income housing units are developed with agency assistance or pursuant to Section 33413, the agency shall require, by contract or other appropriate means, that the housing be made available for rent or purchase to the persons and families of low or moderate income displaced by the redevelopment project, if those persons or families meet the income eligibility and other requirements for that housing. Those persons and families shall be given priority in renting or buying that housing. However, failure to give that priority shall not affect the validity of title to real property. The agency shall keep a list of persons and families of low and moderate income displaced by the redevelopment project who are to be given priority, and may establish reasonable rules for determining the order or priority on the list.
