Spruce Creek Fly-In, Samsula or city limits: who permits your barn slab
The building desk only covers parcels inside the city. Spruce Creek Fly-In sits just past the boundary, and county records code its parcels as unincorporated. A barn or hangar-side shop floor there goes to Volusia County. So does Samsula. Before anyone draws a plan, ask the city Building Division which side of the line your parcel is on.
Inside the city, applications run through the SmartGov portal, and the city's flyer lists "accessory building (shed, carport, barn)" as permit work. Outside it, a true farm barn plays by different rules. F.S. 604.50 frees a nonresidential farm building on bona fide agricultural land from the Florida Building Code and any county or municipal code or fee. Floodplain rules still apply. A dwelling never qualifies, so a barndominium can't use it. Our pole barn slab page covers the whole job, and the concrete contractors page lists the rest of what we pour in the city.
Where a pole barn barndominium slab in Port Orange can sit on your lot
The median single-family lot in the city is about 0.2 acre. Just 767 of its 20,133 single-family parcels run an acre or more. Spruce Creek Estates averages about 1.1 acres, and the Halifax Riverview neighborhood about 0.52 acre. How big a barn you can pour comes down to lot size.
Setbacks in the city's Land Development Code grow with the building. A storage building up to 120 sq ft sits 5 ft from the property line. From 121 to 250 sq ft, it moves to 10 ft from the rear and side lines, or the house's side setback if that's smaller. At 251 sq ft and up, and smaller than the house's floor area, it takes the same setbacks as the house. You'll find the table in LDC Chapter 16, Section 5.
A 24 by 30 barn is 720 sq ft, so it lands in that last bracket. Mark the pad edge and the post lines on your survey before you order a kit. On a 0.2 acre lot, the setback line eats your footprint fast. Finding out on paper that a barn won't fit costs a lot less than finding out after the pour.
