In September 1987, the Homeless Network of Indianapolis, in conjunction with the United Way/Community Service Council, the City of Indianapolis, Office of the Mayor, the Department of Metropolitan Development and All Saints Episcopal Church established a list of priorities for addressing the problem of homelessness in Indianapolis. The top priority on this list was the need for a daytime multi-service agency that could help coordinate the many services offered to homeless individuals around the city. From this priority emerged the Indianapolis Day Center.

On Nov. 21, 1988, the Indianapolis Day Center opened through the cooperative efforts of Shepherd Community, Inc., and the Salvation Army was recruited to manage the agency based on its experience working with homeless persons and with their case management program.

On January 1, 1994, the Indianapolis Day Center’s Board of Directors felt a need to further secularize the identity of The Day Center in order to broaden its base of support. The Day Center shifted to independent management, breaking its long-standing relationship with the Salvation Army, and creating a new tie to the United Way of Central Indiana. Later that month the Board of Directors voted to change the name of the agency in an effort to strengthen its identity, and thus originated Horizon House.

In 1994 Horizon House formulated a long-term strategic plan which called for the relocation of the agency to a larger facility which could accommodate more programs and better facilitate our mission.

Horizon House was able to secure additional funding from Lilly Endowment Inc., Central Indiana Community Foundation, United Way of Central Indiana, Department of Housing and Urban Development, and the AmeriCorps program. This funding allowed Horizon House to purchase the facility at 1033 East Washington Street and to begin implementing the Strategic Plan with additional hours and programming beginning August 8, 2001.
