Full Breakdown
St. 020, covers "any building, structure or equipment that is subordinate and incidental to the lawful principal use of the building or premises", sheds fall squarely under this. 1 allows, by right, one accessory storage structure (a pre-constructed shed), one carport, and one gardening structure (hoop house, cold frame, greenhouse, or vertical vegetable structure) per lot in neighborhood districts, or at any single-family home, and exempts these from the district's usual design requirements, up to a point. A shed of 100 square feet or less and under 10 feet tall is exempt outright from having to match the principal home's architectural style and materials.
A larger shed, up to 200 square feet and 10 feet tall to the roof peak, still qualifies for the exemption only if it sits in the rear one-third of the property and is screened by a solid masonry wall or a decorative wood or vinyl fence at least 6 feet tall. Every shed, regardless of size, must be anchored to resist wind, cannot be placed on a foundation that encroaches a utility easement, and cannot encroach any right-of-way or private access easement; it also can't be used to house mechanical equipment.
Sheds larger than these thresholds lose the design exemption and must instead meet the zoning district's full architectural and setback standards. All accessory structures, including sheds, must comply with the Florida Building Code and St. Petersburg Fire Code, including a backflow preventer requirement if irrigation is added, and establishment requires a lawful principal use already on the lot.
Violations & Fines
An oversized, unanchored, or easement-encroaching shed is a Land Development Regulations violation the POD can cite; because §§ 16.50.020.4.1 and .020.3.2 tie accessory structures to the Florida Building Code, an unpermitted shed can also trigger a building-code case, with Code Enforcement Board fines running up to $250/day past the compliance deadline under § 9-29.
