Philosophical accounts of discrimination distinguish the question of what discrimination is from the question of its wrongfulness. This article addresses these two questions in the context of anti-homeless hostile design of public spaces. Regarding the first question, all forms of anti-homeless hostile design amount to discrimination, with typical cases (for example, anti-homeless spikes or benches) being direct discrimination, but with some cases (for example, CCTV not intended to target the homeless) being indirect discrimination. Regarding the second question, it is argued that all major accounts of the wrongness of discrimination identify the usual, directly discriminatory hostile design as wrongful on account of its harmful or disrespectful character. Most accounts also consider the less common indirectly discriminatory hostile design to be possibly wrongful, especially given the severe disadvantages faced by the homeless in contemporary cities.
