The payment standard is the maximum subsidy CHA can pay on behalf of a family. If the landlord (LL) requests a rent that is above the payment standard that CHA can approve then (1) The LL can either lower the requested amount so that it is within the payment standard. (2) The tenant has the option to pay more than 30% of their income (as long as it does not exceed 40% of their income, or otherwise approved by CHA). (3) The tenant can use their voucher to move to another unit.
