Do I need a permit for shed or accessory structure in Unincorporated Lake County?
It depends. Whether shed or accessory structure needs a permit in Unincorporated Lake County comes down to the details of your project.
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 Unincorporated Lake County
Lake County's own permitting office is the Lake County Office of Building Services, reachable on 352-343-9653 at https://lakecountyfl.gov/building-services. Its online permit portal is https://mcdplus.lakecountyfl.gov/oprs_PT/. 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. Lake County's local amendment to FBC 105.2 exempts a one-story detached tool shed, storage shed, pergola, gazebo, or playhouse on a single-family lot only when it is 120 square feet or less and built by the owner for their own use. The exemption does not authorize work in a special flood hazard area. Larger accessory structures follow Checklist CL1, which requires an approved zoning permit and plot plan, and the zoning approval is valid for only 30 days for submitting the building permit. Under LDR 10.01.01, an accessory structure cannot sit in a required buffer or setback, and on lots under one acre all accessory structures combined cannot exceed 80 percent of the home's main-floor living area. Accessory buildings generally go in side or rear yards, and cargo containers are not allowed as sheds in residential districts.
