210 ILCS 125/11

The Department may designate certified local health departments as its agents for purposes of carrying out this Act. An agent so designated may charge fees for costs associated with enforcing this Act. Where the agent determines that it cannot perform an inspection under this Act, the Department shall perform the inspection and any applicable fees shall be payable to the Department and the agent may not charge a fee. If the Department performs a service or activity for the agent that the agent cannot perform, the fee for the service or activity shall be paid to the Department and not to the agent. In no case shall fees be assessed by both the Department and an agent for the same service or activity.
