The best resource for this information is the local police or the county sheriff's department. They have access to the most current and accurate information and are generally very willing to be helpful.
The Claremont Hills area of Berkeley has many single familly homes with plenty of privacy and beautiful views of San Francisco. It is a tight community with a very active neighborhood watch. If you are interested in viewing specific details of crime statistics for this neighborhood or any other area in Berkeley, then I suggest you take a look at the following site of the Berkeley Police Dept. http://www.ci.berkeley.ca.us/ContentDisplay.aspx?id=7060
