Florida Statutes, Chapter 489, Licenses Required, 489.103, Exemption [7] License requirements do not apply to: Owners of property when acting as their own contractor and providing direct, onsite supervision themselves of all work not performed by licensed contractors: (a) When building or improving farm outbuildings or one-family or two-family residences on such property for the occupancy or use of such owners and not offered for sale or lease, or building or improving commercial buildings, at a cost not to exceed $75,000, on such property for the occupancy or use of such owners and not offered for sale or lease. In an action brought under this part, proof of the sale or lease, or offering for sale or lease, of any such structure by the owner-builder within 1 year after completion of same creates a presumption that the construction was undertaken for purposes of sale or lease.
