California Code, Welfare and Institutions Code - WIC § 4741

An adult person with a developmental disability has the legal right to determine where his or her residence will be. Except in a situation which presents immediate danger to the health and well-being of the individual, the regional center or its designee shall not remove a consumer from a residential care facility against the client's wishes unless there has been specific court action to abridge such right with respect to an adult or unless the parent, guardian or conservator consents with respect to a child.
