Between 1996 and 2001, the Coalition operated as an unincorporated organization. During this period of time, the community interest in homelessness was growing and the membership was expanding to include business, religious, government, health, legal and homeless community representatives.
On December 20, 2001, the Montgomery Area Coalition for the Homeless, Inc. was incorporated as an Alabama nonprofit corporation eligible for tax exemption as an IRS 501(c)3 charitable nonprofit organization. In 2003, the organization officially expanded its activities to include Montgomery, Elmore, Lowndes and Bullock counties. Autauga County was added in 2009. As a result of this expansion, MACH began doing business as the Mid-Alabama Coalition for the Homeless on December 9, 2003.
