The Family Unification Program (FUP) provides Housing Choice Vouchers to youth aging out of the foster care system and to families involved with the child welfare system. In order to determine eligibility for the program, SHHP has developed a local partnership with Colorado Department of Human Services, Division of Child Welfare.
In order to qualify as a FUP eligible youth, the individual must be between the ages of 18-21, who was in foster care on or after their 16th birthday and currently lack adequate housing. Lack of adequate housing includes living in substandard or dilapidated housing, being homeless, displaced by domestic violence, living in an overcrowded unit, or living in housing not accessible due to the nature of his/her disability.
The housing assistance provided to the youth in this program is for a maximum of 18 months.
FUP eligible families are families that the public child welfare agency has certified as families for whom the lack of adequate housing is a primary factor in the imminent placement of the family’s child, or children, in out-of-home care, or the delay of discharge of a child, or children, to the family from out-of-home care and that the PHA has determined is eligible for a Housing Choice Voucher. The housing assistance provided to eligible families is not time-limited.
FUP participants receive a Housing Choice Voucher, funded by the U.S. Department of Housing and Urban Development (HUD). This voucher allows the participant (individual or family) to rent a home in the community from any landlord. Participants pay between 30% and 40% of their monthly-adjusted income towards rent with the balance paid by HUD.
