Health & Saf. Code, § 37922.2

If anticipated rent increases or other increases in housing costs will result in dislocation of residential rehabilitation area residents or will result in residents paying a disproportionately large percentage of their incomes for housing, the local agency shall take every possible action to prevent displacement of all residents as a result of the operation of the residential rehabilitation program in residential rehabilitation areas. Such actions shall include relocation payments to persons and families of low or moderate income, as defined by Section 50093, who are tenants displaced because of the temporary or permanent displacement for rehabilitation work or residential infill construction assisted under this part, or rent increases resulting from rehabilitation, pursuant to the Uniform Relocation and Real Property Acquisition Policies Act of 1970 (42 U.S.C., Sec. 4601) or Chapter 16 (commencing with Section 7260) of Division 7 of Title 1 of the Government Code. Such actions shall also include, but need not be limited to, utilization of all federal, state, or local funding programs which are available for housing subsidies. In allocating funds which may become available through federal revenue sharing and through the federal Housing and Community Development Act of 1974 (P.L. 93-383; 88 Stat. 633), the local agency shall give consideration to measures which will assist in preventing displacement of such residents, the consideration of such measures to be evidenced in writing.

For purposes of this section, displacement includes relocation occurring because of the inability of a person or family of low or moderate income to pay increased rentals resulting from rehabilitation, or involuntary temporary or permanent displacement of such a person or family.

The relocation payments required under this section shall be mandatory only if federal or state funds are available. However, nothing shall preclude the public entity from using local funds or funds from the sale of bonds.
