(2) Prohibits a county human services agency from requesting additional documents to verify excess shelter costs, except when the reported shelter costs are questionable.
(b) Notwithstanding the rulemaking provisions of the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code), the department may implement and administer this section through all-county letters or similar instructions.
