The Plantation Key Courthouse and Detention Center is one of Monroe County's most ambitious undertakings. The project will consolidate the judicial and penal functions that exist on the site into a new state-of-the-art facility.

The project will consolidate the existing functions on the site into a new state-of-the-art 48,240 square foot facility and should take about 30 months to complete.

The tenants of the new space will include:

  • 16th Judicial Circuit of Florida
  • Clerk of Court
  • State Attorney
  • Sheriff's Office
  • Public Works


Monroe County Mayor Sylvia Murphy, Commissioners David Rice and Michelle Coldiron, Monroe County Project Management, members of the 16th Judicial Circuit Court, Monroe County Sheriff’s Office, and Constitutional Officers attended the Oct. 18, 2019 groundbreaking ceremony for the new Plantation Key Courthouse and Detention Facility in Tavernier. 

The tenants will continue to work in the old building adjacent to the construction while the new facility is built. According to Upper Keys historian Jerry Wilkinson, the original building, the sheriff’s substation, was built in 1958 with additions, like the courthouse and other government offices, dedicated in 1967.

“This is going to be a major change in this beautiful community that has been a long time coming,” said David Rice, Monroe County Commissioner. “There was a great deal of thought put into this project and I would like to express a special appreciation to the staff and the consultants who juggled how to build this and keep everything going while we are under construction.”
