Do I need a permit for shed or accessory structure in Unincorporated Santa Rosa County?

Permit may be required

It depends. Whether shed or accessory structure needs a permit in Unincorporated Santa Rosa 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 Santa Rosa County

Santa Rosa County's own permitting office is the Santa Rosa County Development Services - Permitting & Building Compliance office, reachable on 850-983-1877 at https://www.santarosa.fl.gov/170/Permitting-Building-Compliance. 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 Santa Rosa County Ordinance 2010-17, a residential storage building can be built without a building permit through an Accessory Exemption when it is not designed for habitation, sits on or next to a lot with an existing single-family home in unincorporated Santa Rosa County, has 600 square feet or less of gross floor area plus covered area, is subordinate to the main dwelling, and is not in a special flood hazard area. The exemption is not automatic. It requires the Accessory Exemption application and a scaled plot plan, a $35.00 administrative fee, and a $25.00 zoning review fee, and a contractor who builds the shed must also sign the application. The exemption does not cover plumbing, electrical, mechanical or gas work in the building, which still needs its own permits and inspections, and it does not waive setbacks, height limits, flood rules, Florida Product Approval or termite treatment requirements. Building without the required exemption or permit violates county ordinance, and the county fee schedule charges triple the basic permit fee when work starts before a required permit is issued.
