Welcome! My goal is to do my very best to understand your situation and to provide a full and complete answer for you.
Good morning. This comes under the Florida Fire Prevention Code statute, specifically the following two statutory provisions....as you can see electric grills are exempt from this prohibition:
NFPA 1:10.11.7: For other than one- and two-family dwellings, no hibachi, gas-fired grill, charcoal grill, or other similar devices used for cooking, heating, or any other purpose, shall be used or kindled on any balcony or under any overhanging portion or within 10 ft (3 m) of any structure. Listed electric ranges, grills, or similar electrical
apparatus shall be permitted. (Per NFPA 1, Uniform Fire Code, Florida 2007 Edition)
NFPA 1:220.127.116.11: Storage Within Residential Buildings. Storage of cylinders within a residential building, including the basement or any storage area in a common basement storage area in multiple-family buildings and attached garages, shall be limited to cylinders each with a maximum water capacity of 2.7 lb (1.2 kg) and shall not exceed 5.4 lb (2.4 kg) aggregate water capacity for smaller cylinders per each living space unit.
