People with intellectual disabilities or psychiatric disorders who live in ordinary neighbourhoods often have little contact with fellow residents without disabilities. Recent research suggests that we should not strive for warm contacts based on familiarity and shared values between utterly different groups in urban areas. Daily life between people with and without disabilities is described as a process in which boundaries are negotiated. This study builds on that observation. It was based in a middle sized town in the Netherlands and consists of a survey among people with intellectual or psychiatric disabilities and neighbourhood residents (not being support staff or relatives of people with disabilities); semi structured interviews and participant observation. We found that fruitful encounters between different groups depend on built-in boundaries in contacts. Positive encounters occur when roles are clear and boundaries do not have to be negotiated because they are given. Both parties benefit from boundaries and fixed roles: people with disabilities do not need social reflexivity or intricate social skills to find their way in the situation; people without disabilities can end the contact without being rude. In line with previous research we also found that positive neighbourhood contacts are usually light and superficial and result in conviviality rather than long term relationships.
