Pursuant to state regulations, the jail must have a written policy defining the facility's visitation policies. State regulations require that each prisoner be allowed one hour of visitation each week, that prisoners submit a list of visitors, and that prisoners be allowed to visit with their children. Visitors shall register before being admitted to the facility and may be denied admission for refusal to register, for refusal to consent to a search, or for any violation of posted institutional rules.  Probable cause must be established in order to do a strip or body cavity search of a visitor.  When probable cause exists, the search must be documented.
