Do I need a permit for shed or accessory structure in Sanford?
Yes. In Florida, shed or accessory structure generally requires a permit, and Sanford 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 Sanford
Seminole County's own permitting office is the Seminole County Building Division, reachable on 407-665-7050 at https://www.seminolecountyfl.gov/departments-services/development-services/building. Its online permit portal is https://semc-egov.aspgov.com/Click2GovBP/index.html. 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. Sanford's Shed/Gazebo/Pergola Guidelines split sheds at 10 by 12 feet. A shed of that size or less needs a signed and notarized Shed Affidavit and a site plan; a larger shed needs digitally signed and sealed engineered drawings and a Sanford Product Approval Specification Form. The Building Division does not inspect sheds of 120 square feet or less. The notarized affidavit, filed at submittal, serves as the final inspection approval, and a shed set outside the approved location may have to be moved or removed at the owner's expense. A concrete slab under a non-engineered shed of 120 square feet or less needs its own Slab Permit in addition to the shed permit. Under Land Development Regulations Schedule F, accessory structures are not permitted in front or side yards, and an accessory building of 200 square feet or more must match the house in materials, color, and architectural style.
