The permit answer

No permit for a plug-in swap. Orange County's own guide: an appliance that plugs into an existing outlet does not require a permit. A hardwired connection, a new circuit, or new plumbing — a first-time install or a moved supply/drain — is electrical/plumbing work that does.

Key facts before you start

Drain connection (FBC-P 8th ed §409.4): the waste line must land on a wye branch at the kitchen-sink tailpiece, on the disposer's dishwasher connection, or through an air break to a standpipe, AND 'rise and be securely fastened to the underside of the sink rim or counter top' — strap/zip-tie it, don't drape it. The high loop has a FLOOR AND A CEILING: Bosch wants a portion at least 20" (508 mm) above the CABINET floor but says 'Do not exceed 43" in drain hose height,' with total hose length — including any run to an air gap — capped at 150" (3800 mm); Whirlpool wants ≥20" and an AIR GAP below that; GE hangs the loop 32" min and makes an air gap MANDATORY if local code requires one OR the waste tee sits less than 18" above the floor. Higher and longer is not safer.
Draining into a garbage disposal: knock the dishwasher-inlet knockout plug INTO the disposer with a hammer + screwdriver and pull it out with needle-nose pliers BEFORE clamping the hose (Whirlpool) — GE: 'DISHWASHER WILL NOT DRAIN IF PLUG IS LEFT IN PLACE,' the #1 first-run 'defect' and an avoidable non-warranty service call. A plain wye tailpiece has no plug — skip the step there.
Handling + anchor order: GE says lay the unit on its BACK — 'Do not place the dishwasher on its side' — never kick the wood shipping base, and pull the 4 leveling legs off it with a 15/16" socket before discarding it. DECIDE the anchor method BEFORE fitting brackets: Bosch top mount is for wood/easily drilled tops, side mount for solid surface/marble/granite (snap the bracket's rounded end off at the perforation), and 'once the mounting brackets are installed on the dishwasher, removing them is difficult and will damage the mounting brackets and the dishwasher.' Level side-to-side with the feet, front-to-back with the center screw (Bosch). Never leave it unanchored — tip-over hazard.
Water hookup: 3/8" minimum HOT line — copper with a compression fitting or a dishwasher-rated braided line; Whirlpool: 'Plastic tubing is not recommended,' and the 3/8" compression x 3/4" hose fitting with a 90° elbow is usually NOT in the box. Supply pressure 20–120 psi (GE, Whirlpool) / 15–145 psi (Bosch), water heater set ~120°F. Bosch traps: make every solder joint BEFORE connecting the supply line and keep the heat source at least 6" (152.4 mm) from the machine ('temperatures required for soldering and sweating will damage the dishwasher'); flush the incoming line ~5 minutes to clear debris; use thread compound/PTFE tape on threaded joints but 'do not use pipe sealant on compression fittings.'
Electrical: dedicated, grounded 120V branch circuit — GE 15- or 20-ampere breaker or time-delay fuse, 2-wire-with-ground rated 75°C; Bosch 15 A on #14 AWG copper minimum. Never an extension cord or adapter plug. Most units ship for HARDWIRE via junction box; cord-and-plug conversion takes the brand's kit — GE lists WX09X70910 (5 ft 4 in), GPFQDCORD (6 ft) and WX09X70911 (7 ft 9 in), cautioning 'the use of any cord over 6 feet long will void the warranty if local codes restrict the length of the power cord,' so check local code before the 7 ft 9 in cord. Routing (GE): a power cord with plug must pass through its OWN hole and the water line must not share that hole, while permanent wiring may share the drain-hose/water-line hole; 1-1/2" max diameter, edges smooth and rounded, bushing if the cabinet wall is metal.
Orlando/Orange County permits: OC's published answer for a like-for-like PLUG-IN swap is 'No, if the appliance plugs in to an existing outlet, it does not require a permit' — but 'a new electrical outlet or move an outlet? Yes, you need an electrical permit,' which is exactly a hardwired→cord-and-plug conversion. HB 803 cannot rescue this job: s. 553.79(1)(g)2.b. (Ch. 2026-63, eff. 7/1/2026) excludes 'any electrical, plumbing, structural, mechanical, or gas work' from the under-$7,500 exemption at ANY value, and a dishwasher swap is both plumbing and electrical. That trade work for pay is licensed-contractor territory in FL; an owner-occupant may still DIY under an owner-builder permit. 'Orlando' splits between City of Orlando and unincorporated OC — confirm with OC Building Safety 407-836-5550.
