No. In Florida, jails are typically under the authority of the county or the Sheriff of said county, and they are used to hold those awaiting trial, sentencing, or serving a sentence of 364 days or fewer. The durational aspect is the easiest to illustrate of the differences between jail and prison, and it provides some insight into why knowing where you’re headed is so important. If a person’s total sentence is 364 days or fewer, they will be housed in the county jail for the duration of that sentence. Accordingly, if a person is sentenced to 12 months and 1 day or more, that sentence will be served at a state prison. Unlike the county jail, prisons are under the authority of the Department of Corrections.
