The answer
For the conventional tenant-based HCV formula, gross rent is rent to owner plus the PHA utility allowance. HAP is the lesser of the applicable payment standard minus PHA-determined TTP or gross rent minus TTP, with a zero floor. PHA payment to owner cannot exceed rent to owner; any remainder may be a utility reimbursement.
