Marion County, FL Accessory Structures: Shed Rules (2026)

Under Marion County Land Development Code (LDC) Sec. 4.3.27 (Ord. No. 17-08, April 11, 2017), accessory structures such as sheds, storage buildings, and detached carports that do not exceed 12 feet by 12 feet in size may be exempted from the otherwise-required side or rear setbacks. To qualify, the adjacent property owner and the subject property owner must provide a signed and notarized statement, with a site plan showing the proposed location and setback dimensions, submitted to the Growth Services Department before placement. The exemption applies only to residentially-zoned properties and agriculturally-zoned properties less than one acre, does not apply where streets or rights-of-way are adjacent to the side or rear lot lines, and no structure may extend over an easement without written approval of the easement holder. A principal structure must already exist on the lot. For sheds and other accessory structures, Florida Statutes Sec. 553.792(1)(a) requires the county to approve or deny a complete building-permit application within 30 business days for structures under 7,500 square feet. Property owners should confirm whether their specific shed requires a building permit with Marion County Building Safety before installation.
