California Code, Health and Safety Code - HSC § 17975.1

(a) The relocation benefits required by this article shall be paid by the owner or designated agent to the tenant within 10 days after the date that the order to vacate is first mailed to the owner and posted on the premises, or at least 20 days prior to the vacation date set forth in the order to vacate, whichever occurs later.

(b) If there are fewer than 10 days between the first posting and mailing of the order to vacate and the vacation date, the relocation benefits shall be paid by the owner or designated agent to the tenant within 24 hours after the notice is posted and mailed. The local enforcement agency shall attempt to provide telephonic or written notice to the owner to notify the owner that the benefits are payable immediately. Failure to provide the notice as specified in this section shall not relieve the owner of any obligations imposed by this article.

(c) If a tenant is entitled to relocation benefits pursuant to Section 17975, the local enforcement agency shall provide either telephonic or written notice to the tenant of his or her entitlement to the benefits. Written notice may be satisfied by posting a written notice on the premises stating that tenants may be entitled to relocation benefits.
