The Fair Housing Improvement Act of 2025 seeks to significantly expand protections under the Fair Housing Act by prohibiting discrimination based on an individual's source of income , veteran status , or military status . This legislation explicitly defines "military status" as being a member of the uniformed services and "veteran status" as being a former member of the Armed Forces. It also provides a comprehensive definition for "source of income," encompassing various forms of housing assistance, social security benefits, court-ordered payments like child support, and other lawful funds such as savings and investments. The bill amends several sections of the Fair Housing Act, including those related to the sale or rental of housing, residential real estate transactions, and brokerage services, to include these newly protected characteristics. It ensures that individuals cannot be denied housing or face discriminatory practices due to how they lawfully obtain their income or their service history. Furthermore, the legislation clarifies that entities providing services or assistance to individuals receiving federal, state, or local housing aid are not in violation of the act, and it extends the certification period for state and local fair housing agencies to adapt to these new requirements.
