Florida state law does not make it unlawful for a sex offender to live in a certain location or with others who are in the public registry (F.S. 775.215). Nonetheless, there are sometimes local codes that restrict where offenders or predators are allowed to reside, with whom they are allowed to interact, and allowable proximity to certain parts of the community. You can get that information from your local sheriff.
Offenders or predators are allowed to live in the same residence as children, unless specifically directed by a court ruling (available via the Department of Corrections or Department of Juvenile Justice).
