Cal. Health and Safety Code § 34178.8

(a) Notwithstanding Section 33411.3, if all or any portion of a redevelopment project was developed with low- or moderate-income housing units and low- or moderate-income housing units were developed with redevelopment agency assistance or pursuant to Section 33413, the redevelopment agency’s housing successor designated under Section 34176 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 and to a person of low or moderate income who is a descendant of the person displaced by the redevelopment project and who, at the time of displacement, was not living in the household or had not yet been born, 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 redevelopment agency’s housing successor shall keep a list of persons and families of low and moderate income who are to be given priority pursuant to this section, and may establish reasonable rules for determining the order or priority on the list. (b) For purposes of this section, “descendant” shall have the meaning provided in Section 6205 of the Probate Code.
