Improvements such as painting, flooring, replacing cabinets and countertops in the same location, and other non-structural work generally do not require a permit.
Florida Building Code section 105.1 states, "Any owner or owner’s authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any impact-resistant coverings, electrical, gas, mechanical or plumbing system, the installation of which is regulated by this code, or to cause any such work to be performed, shall first make application to the building official and obtain the required permit.". FBC Section 105.2 states what is exempt from permitting.
