Here’s a local link (Board letter) I found dated 2003 that states that in order to receive a “Section 8” voucher, an applicant must have submitted to a criminal background check. However, these tenants did not have to keep their criminal background check current during their tenancy. Supvsr Cox proposed that these recipients should have to report any criminal conviction they sustained while a tenant to the County Housing Authority. Don’t know if this new ordinance was ever passed by the BOS.
Of course, enforcement could be problematic and also labor-intensive.
