Each housing option has a Handbook, which specifies differing policies, procedures, and guidelines for behavior (including, among other information, policies for guests and policies for cleaning, etc.*). It is imperative that you familiarize yourself with these Handbooks when preferencing your housing options.
*There may be differences in the rules between locations within a specific housing option.
