Full Breakdown
Storage sheds are permitted accessory structures under St. Lucie County LDC 8.00.03(B), which lists enclosed storage structures and greenhouses. LDC 8.00.02(B) caps total accessory-structure coverage at thirty-five percent of the lot's maximum permitted building area, and 8.00.02(C) limits a residential enclosed storage structure that exceeds the height of the main house to twenty feet, set at least five feet behind the front facade. Sheds must meet the setbacks of the zoning district and, for most sizes, need a building permit issued under the Florida Building Code for wind-load and anchoring in this hurricane-prone coastal county. Fences or walls around a shed follow separate LDC fence rules. Port St. Lucie and Fort Pierce apply their own municipal codes.
Violations & Fines
A shed built without a required permit, over the 35% coverage cap, or inside a required setback is a Land Development Code violation; St. Lucie County Code Compliance can order a permit, relocation, or removal and impose daily fines.
