Do I need a permit to build a pole barn in Florida?
In nearly every Florida county you need a permit for a pole barn. Florida Statutes § 604.50 exempts nonresidential farm buildings on agriculturally classified land from the Florida Building Code and local permit requirements — the key trigger is ag-land classification from your county property appraiser, not building size. Flood-zone requirements still apply regardless. Confirm your parcel's ag classification and the applicable county rules before you sign a contract. <!-- source: https://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0600-0699/0604/Sections/0604.50.html -->
