How long Sarasota County Commissioners get to be Sarasota County Commissioners is a question that may be decided at the ballot box. Terms limits have been proposed before. Now, a referendum is likely to be voted on next year that would limit commissioners’ terms to three. Currently, there are no term limits. County Commissioners serve for four years at a time. Back in 1998, voters overwhelmingly passed a referendum limiting Commissioners to two terms. That measure was eventually ruled unconstitutional by the Florida Supreme Court.
