Recently there has been a high profile case in the UK concerning a religious christian couple who own a hotel. Due to their personal religious beliefs their policy was to refuse a room to couples who were not married. They refused a 'married' homosexual couple a room on the grounds that they were not of the same 'orientation', which went against their religious values. They said that it would feel wrong to allow it and that they would feel more trepidation answering to God than the justice system.
According to halacha would you be considered an 'accomplice' to the aveirot that are committed under your premises (be it unmarried or homosexual couples who are 'looking to hire a room')? Or would it be permitted to rent out a room to anyone i.e. once hired out it is no longer any of your business or jurisdiction and you cannot be held accountable?
