Short answer: permit required. Orange County explicitly requires an electrical permit for new or moved outlets and any new circuit (FBC 105.1 covers wiring alterations). The full rule and its official source are below, with the code requirements and mistakes that trip up Orlando homeowners.

Key facts before you start

The dividing line is the panel: running extension cords from a portable generator directly to appliances needs no permit, but ANY connection to house wiring — a transfer switch, an interlock kit, or an inlet box — is an electrical alteration that requires an Orange County electrical permit and inspection, the same FBC 105.1 rule that covers any new circuit (Orange County).
Never plug a generator into a wall outlet. That so-called suicide cord back-feeds your panel and energizes the utility lines outside your house — line crews restoring your street can be killed by it, and it bypasses every overcurrent protection you own. CPSC's generator guidance is blunt: power appliances by cord, or connect through a properly installed transfer switch — those are the only two options (CPSC).
Interlock kit vs transfer switch, in one breath: an interlock is a sliding plate on your existing panel that physically forces the main breaker OFF before the generator back-feed breaker can turn ON — cheap, but it must be a kit listed for your exact panel make and model, not a universal plate. A transfer switch is a separate small panel serving hand-picked circuits. Both live inside the permit, and checking the kit's listing, the wire sizing, and that the interlock actually blocks the main is exactly what the electrical inspection is for.
The generator itself stays outside — 20 feet or more from doors, windows, and vents, exhaust pointed away, with working CO alarms inside. CPSC counts more than 80 consumer deaths a year nationally from portable-generator carbon monoxide, and a garage with the door open does not count as outside (CPSC).
Size the hookup before the storm, not during it: add up the running watts of what you actually need (refrigerator, a window AC, lights, phone charging), then check the largest motor's starting surge against the generator's surge rating, and use the cord gauge the manufacturer's manual specifies at that length. An undersized cord at full load is a heat problem inside an already stressful week (CPSC).
A permanently installed standby generator is a different project entirely: it adds a gas permit and fuel-line work to the electrical permit, placement clearances from openings and property lines, and gas piping is licensed-trade work in Florida at any dollar value — HB 803's under-$7,500 exemption never covers electrical or gas work, so neither route around permitting exists for this job (Orange County).
