The third approach to effecting change in the Housing Choice Voucher program disallows the business strategy of targeting voucher holders through administrative rules. It targets only the landlord that exclusively leases to voucher holder and by forcing the landlord to market at least one unit in a building to a non-subsidized tenant (or sustain the vacancy), it would reduce the profits associated with the business strategy. The rule could be added to the Housing Quality Standards enforced at the time of application through inclusion in the Request for Tenancy Approval form that each landlord must complete before a HCV contract is created (CHA, 2013d). The addition of a question about the number of units in a building would allow a queries of data to show the number of active housing assistance payment contracts at a particular address alongside the number of inhabitable units. Verifying the housing units in a two- to four-unit property could be an easily added inspection item.

The requirement could be narrowly tailored to address the particular problem-causing landlords. Landlords who develop and implement a supportive services plan could receive a waiver, releasing them from the marketing requirement since they should have already developed such a plan to qualify for CHA project-based housing vouchers. A unit that is owner-occupied would satisfy the one-unit minimum, further limiting the policy to investor-owned two- to four-unit buildings. Still, the policy would likely require changes in federal rules and regulations for the Housing Choice Voucher.
