Public Notice of Regional Fair Housing Study and Related Community Survey

The St. Louis HOME Consortium is conducting an Analysis of Impediments to Fair Housing Choice (AI). The consortium includes St. Louis County, St. Charles County, Jefferson County, the cities of Florissant and O'Fallon, and the Housing Authority of St. Louis County. The study identifies barriers to equal access to housing and neighborhood opportunities and proposes strategies to overcome those barriers. It is required by the U.S. Department of Housing and Urban Development (HUD) so that the Consortium members can continue to receive federal housing and community development funds.

The community's opinions and perceptions are an important part of this planning process, and everyone is invited to participate. Your input will provide essential information to local policymakers, city and county staff, housing providers, social service providers, lenders, and affordable housing advocates.   

Residents can learn more about the project and take an online survey. To be notified when drafts of the study are available, please subscribe to our mailing list.
