RSB zoning allows for people in the outdoor amusement industry (ie: carnival, circus, etc) to store and work on their equipment, on their residential property. Hillsborough County had a well established showbusiness population when Florida created zoning laws. These land owners did not use their property commercially, but did need to maintain their commercial equipment while they were at home. The county recognized this unique situation and crafted a special zoning to accommodate these landowners. It allows for carnival rides, concession trailers, large trucks, RVs, performance riggings, exotic animals, etc. It exists countywide, but is concentrated in Gibsonton.
RSB is one of the things that makes Hillsborough special.
