Do I need a permit for shed or accessory structure in Port St. Lucie?
Most likely yes. Shed or accessory structure usually requires a permit in Florida. Confirm the specifics with Port St. Lucie.
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 Port St. Lucie: City of Port St. Lucie issues its own building permits. Permitting office is in Building B of the City Hall Complex.
Florida and local notes for Port St. Lucie
St. Lucie County's own permitting office is the St. Lucie County Building & Code Regulation Division, reachable on (772) 462-1553 at https://www.stlucieco.gov/departments-and-services/planning-and-development-services/permitting-zoning. 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. Port St. Lucie publishes a dedicated Accessory Structure Permit application and checklist that covers sheds and garden structures, and asks for product approval, a site plan or survey, and signed and sealed construction plans. Under City Code 158.217(C)(2)(h), detached storage buildings, workshops, and playhouses on single-family lots are capped at 500 square feet cumulative, and any over 300 square feet must match the appearance and design of the house. City Code 158.217(C)(1) keeps accessory structures out of the area between the front corners of the house and the front property line and requires at least 10 feet from the rear property line. The accessory structure checklist says a formboard survey is required when a concrete foundation is poured.
