The purpose of the Housing Unhoused Disabled Veterans Act is to improve access to housing for disabled veterans by changing how certain disability benefits are considered when determining eligibility for housing assistance programs. The main objective is to ensure that veterans receiving specific disability benefits do not face barriers to securing housing support due to their income being counted against them. Key provisions of the Act include the exclusion of disability benefits received under chapters 11 and 15 of title 38 from being counted as income for the supported housing program.
