From the Code of Federal Regulations concerning the Shelter Plus Care Program, 24 C.F.R. § 582.300(a):
Each recipient must provide for the consultation and participation of not less than one homeless individual or formerly homeless individual on the board of directors or other equivalent policy-making entity of the recipient, to the extent that the entity considers and makes policies and decisions regarding any housing assisted under this part or services for the participants. This requirement is waived if the applicant is unable to meet the requirement and presents a plan, which HUD approves, to otherwise consult with homeless or formerly homeless individuals in considering and making such policies and decisions.
Oh, of course. I bet the housing authority just wanders down into the Tenderloin, finds a guy in a Thunderbird-induced stupor, pokes him with a stick until he wets his filthy jeans and wakes up, coughing and hacking, and then asks him "Hey, how would you like to be on our committee?"
