Do I need a permit for shed or accessory structure in Naples?
Yes. In Florida, shed or accessory structure generally requires a permit, and Naples 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.
Florida and local notes for Naples
Collier County's own permitting office is the Collier County Building Plan Review and Inspection Division, reachable on 239-252-2400 at https://www.collier.gov/Business-Resources/Building-Permits-Construction. Its online permit portal is https://cvportal.collier.gov/cityviewweb. 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. Under Naples Code Sec. 56-95, a utility building cannot exceed 100 square feet, cannot have any side longer than 10 feet, cannot be attached to another structure, and must meet the zoning district's setbacks. The city's shed checklist says a shed below the required flood elevation needs at least two flood vents on different walls and flood-resistant materials, and single-story accessory structures are not allowed in VE zones. Sheds within sight of the beach or seaward of the Coastal Construction Control Line must meet the Sec. 52-61(b) glazing and exterior lighting rules, and the city permits every accessory structure separately.
