HUD Handbook 4350.3 § 3-25

Applicants may be assisted only after it is determined that they meet the eligibility criteria
          for the program and the project. This requirement is intended to ensure that an available
          subsidy is provided to families that are eligible under the program rules and not provided
          to ineligible families. Determining eligibility requires that the owner verify information
          that is provided by the applicant on the application form and in subsequent interviews.
          In general, applicants are not required to disclose their status with respect to any
          protected basis; however, if the family requests a reasonable accommodation based
          upon a disability, the family must disclose its disability status.

          Chapter 5, Section 3, of this handbook provides general information and tips on verifying
          all types of information, including methods to avoid accepting tampered documents and
          detailed information on verifying income. This section addresses verification of eligibility
          factors, other than income, about which information must be collected in order to
          determine eligibility.
