HUD Handbook 4350.3 § 2-17

A.      Owners must not purposely provide false information to applicants about the
                availability of units that limits the living options of prospective tenants based on
                race, color, religion, sex, disability, familial status, or national origin of the
                applicant or persons associated with the applicant.

        B.      Examples of such prohibited actions include, but are not limited to, the following:

                1.      Indicating by words or actions that an available unit has already been
                        rented;

                2.      Using deeds, trusts, or other lease requirements to keep a potential
                        tenant from renting an available unit;

                3.      Refusing to inform interested individuals, either verbally or through
                        actions, that suitably priced units are available to be rented; and

                4.      Providing false or inaccurate information about the availability of units to
                        anyone, (including discrimination testers), regardless of whether the
                        person is actually looking for housing.
