California Code, Health and Safety Code - HSC § 34330

(a) Assist in relocating in suitable housing accommodations at rentals within their means persons of low income who have been or will be deprived of dwellings within areas or buildings which have been or will be cleared or demolished. In connection with any project, an authority shall maintain or provide for the maintenance of tenant placement service in which there shall be recorded lists of untenanted, suitable dwellings available to persons of low income and shall furnish such information to such persons. An authority shall from time to time make studies and surveys of dwelling units which may become unoccupied and available to persons of low income and shall also make arrangements with owners and lessors of such dwellings for registration thereof with the tenant placement service. In connection with any project, an authority may pay so much of the necessary cost of removal of persons of low income, and of business or commercial tenants, from the area or buildings to be cleared for the development of the project to suitable locations in such cases and in such amounts as may be approved by the authority. Removal costs so paid by an authority shall be included in the project cost.

(b) Exercise the powers set forth in subdivision (a), in connection with the relocation of persons of low income who are displaced by any public or private improvement within its area of operation. The financing of such relocation activities by an authority shall be arranged by contract with the public or private agency undertaking the improvement which makes such relocation necessary.

(c) Admit to a dwelling in any project of the authority any person or persons residing in an area or building to be cleared or demolished as described in subdivision (a) or (b), if the probable aggregate annual income of such person or persons does not exceed the income limit for continued occupancy established by the authority for the dwelling to which such person or persons is admitted.
