Housing for Women Veterans Act This bill reauthorizes through FY2022 the Supportive Services for Veterans Families program, which provides financial assistance for supportive services for very low-income veteran families in permanent housing or transitioning from homelessness. Under the bill, a specified amount of such funding shall have a focus on providing assistance to women veterans and their families. The bill also requires the Department of Veterans Affairs to complete an analysis of programs that provide assistance to women veterans who are homeless or precariously housed to identify areas for improvement in such programs.
