Summary
Sheds, utility buildings, and greenhouses in unincorporated Walton County must meet the same setback and distance standards as other structures under Land Development Code Sec. 2.02.00(B)(2). Any accessory building storing hazardous, incendiary, or noxious material has to sit at least 100 feet from every property line, and none of these buildings can encroach into the setback along an abutting right-of-way.
2.Storage Buildings, Utility Buildings, Greenhouses.a.No accessory buildings used for industrial storage of hazardous, incendiary or noxious materials shall be located nearer than 100 feet from any property line.b.Storage buildings, greenhouses, and the like shall be approved only in compliance with standards for distance between buildings, and setbacks, if any, from property lines.c.Storage and other buildings regulated by this Section shall not encroach into any required building setback from an abutting right-of-way.d.Storage and other buildings regulated by this Section shall be included in calculations for impervious surface, floor area ratio, or any other site design requirements applying to the principal use of the lot.e.Vehicles, including manufactured housing, travel trailers and mobile homes, shall not be used as storage buildings, utility buildings, or other such uses.
Full Breakdown
The 100-foot hazardous-materials setback is the strictest number in the section and applies to industrial storage of hazardous, incendiary, or noxious materials specifically, not to an ordinary garden shed. Ordinary storage buildings and greenhouses still have to be approved against the standard distance-between-buildings and property-line setback requirements that apply to the zoning district the lot sits in, so a shed in a Residential Preservation lot follows a different setback than one in a Large Scale Agriculture parcel. Every storage building also counts toward the lot's impervious surface calculation, floor area ratio, and any other site design number that already applies to the principal use, so adding a shed can push a lot closer to its stormwater or FAR ceiling even when the shed itself is small.
The code closes off a workaround some owners try: a vehicle, a piece of manufactured housing, a travel trailer, or a mobile home cannot be used in place of a permitted storage building, utility building, or similar accessory use.
Violations & Fines
A storage building placed inside the right-of-way setback, closer than 100 feet to a property line while holding hazardous or noxious material, or built by converting a trailer or mobile home into unpermitted storage is enforced as a Land Development Code violation through Walton County Code Enforcement under Chapter 7 and F.S. ch. 162, with cases referred to the county's Special Magistrate.
