If the adult family home agrees to manage a resident's personal funds, the home must do all of the following:

(1) Hold, safeguard, manage, and account for the personal funds of the resident deposited with the home;

(2) Have a written authorization from the resident;

(3) Deposit a resident's personal funds in excess of one hundred dollars in an interest-bearing account or accounts separate from any of the home's operating accounts, and that credits all interest earned on residents' funds to that account;

(4) If funds are pooled accounts, there must be a separate accounting for each resident's share; and

(5) Keep a resident's personal funds that do not exceed one hundred dollars in a noninterest-bearing account, interest-bearing account, or petty cash fund.
