Whenever a county requests additional unmet shelter needs funds so as to cancel escape assessments upon the homes of welfare recipients improperly granted the homeowners’ exemption, such request is deemed a voluntary act of the county and the county shall assume the burden of all the costs in compliance with this act. For this reason, the act involves no mandated acts within the meaning of Section 2164.3 of the Revenue and Taxation Code and no state reimbursement pursuant to that section is required.
