The Fair Housing Improvement Act of 2025 aims to enhance protections against discrimination in housing by adding new categories to the existing Fair Housing Act. Its main objective is to ensure that individuals are not denied housing opportunities based on their source of income, veteran status, or military status. Key provisions of this legislation include the definition of "source of income," which encompasses various forms of financial assistance such as housing vouchers, Social Security benefits, child support, and other lawful income sources.
