A central element of community response to controversial human service facilities is the socio-spatial construction of stigma. This paper develops a conceptual framework for understanding the constitution and role of stigma in community rejection of human services, particularly those associated with homelessness and HIV/AIDS. Three facets of stigma concerning homelessness and HIV/ AIDS (non-productivity, dangerousness, and personal culpability) are offered as a way of understanding the rising tide of community rejection toward human service facilities.
