Do I need a permit for shed or accessory structure in Unincorporated Union County?
Yes. In Florida, shed or accessory structure generally requires a permit, and Unincorporated Union County is no exception.
Florida has no statewide small-shed exemption. The widely repeated rule that a shed under 120 square feet needs no permit comes from the model International Codes, and Florida did not adopt it: section 105.2 of the Florida Building Code, Building exempts only specified gas, mechanical and plumbing work, with no category exempting detached accessory structures. Where a size threshold exists it is a local ordinance, and it genuinely differs, so ask your building department for the line that applies at your address. Any shed with electricity, plumbing or a permanent foundation needs a permit regardless of size, and zoning setbacks, flood zone rules and wind anchoring apply even when no building permit is required.
Local detail for Unincorporated Union County: Permits for unincorporated Union County are issued by the Union County Building Department. Applications are completed online through Cloudpermit. Building Inspector Wilson Whidden.
Florida and local notes for Unincorporated Union County
Union County's own permitting office is the Union County Building Department, reachable on (386) 496-2676 at https://unioncounty-fl.gov/building-department/. Its online permit portal is https://us.cloudpermit.com/login. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. Ask specifically about the size that triggers a permit and about setbacks, since those are set locally and are the two things people most often get wrong on a shed.
