Most forms of supervision include a condition giving law enforcement officers the right to search without probable cause or even reasonable suspicion.  That is, while under court supervision, you generally lose the protection of the Fourth Amendment.  Typically, searches while under supervision include: searches of your person, your home, your vehicle and your workplace.  This has particular significance for those who live with you.  If you're on probation, parole, or supervised release, an officer can come into your home- without reason or warning-and search not just your bedroom, but also the common areas: kitchen, bathroom, family room, etc.  Although it can be awkward to discuss these things with roommates and family, it's safer for everyone (including you) if all the people you live with understand the added risk to their privacy.
