(a) Unless there is a live-in aide:

(1) For a family residing in congregate housing, the payment standard is the zero-bedroom payment standard amount on the PHA payment standard schedule. For a family residing in congregate housing in an exception area, the payment standard is the HUD-approved zero-bedroom exception payment standard amount.

(2) However, if there are two or more rooms in the unit (not including kitchen or sanitary facilities), the payment standard for a family residing in congregate housing is the one-bedroom payment standard amount.

(b) If there is a live-in aide, the live-in aide must be counted in determining the family unit size.
