I am not aware of any public site that offers this type of information about this house, or any other house. The police department are not very forthcoming with this information either. The best way to find out about a particular house is to literally knock doors and ask the neighbors! I always recommend that my clients do this as part of their due diligence. You can, however, pull registered sex offenders at http://corrections.utah.gov/services/sonar.html.
I don't see this home listed on the MLS, nor has it sold across the MLS in the past 15 years. It is an oddity, in that there are two homes, one in front, one in back.
Hope this helps!
