Housing cooperatives?

As a legal entity, a co-op can contract with other companies or hire individuals to provide it with services, such as a maintenance contractor or a building manager. It can also hire employees, such as a manager or a caretaker, to deal with specific things that volunteers may prefer not to do or may not be good at doing, such as electrical maintenance. However, as many housing cooperatives strive to run self-sufficiently (and recognize the economical efficiency of doing so), as much work as possible is completed by its members.
