Short answer: usually treated as minor no-permit work. FBC 105.2 strictly exempts only repairs that don't replace fixtures or valves, and Orange County publishes no fixture-swap exemption — confirm a full toilet swap with OC sub-trades at 407-836-5564. The full rule and its official source are below, with the code requirements and mistakes that trip up Orlando homeowners.

The permit answer

Check with your building department. Strictly read, FBC 105.2 exempts only repairs that do NOT replace fixtures or valves, and Orange County publishes no fixture-swap exemption — commonly treated as minor work, but confirm (OC sub-trades: 407-836-5564).

Key facts before you start

BEFORE buying, measure the rough-in: finished wall to the CENTER of the closet (floor) bolts. Kohler standard is 305 mm (12"); 10" and 14" also exist. A 12" bowl will not seat on a 10" rough-in — use an offset flange for a small mismatch, don't force it.
Press the wax seal onto the TOILET outlet (not the flange), lower over the flange, set with full body weight — then DO NOT lift or rock the bowl; a broken seal means a NEW wax ring, never re-seat.
New 5/16" T-bolts AND tank bolts: tighten to SNUG only — overtightening cracks vitreous china; alternate side-to-side, verify the tank sits level front-back and left-right, and cut floor bolts extending >=1/4" above the nut.
Flange height (Fluidmaster 7530 waxless): flush-to-1/4" below floor = one seal; ~1/2" above = stack two; more than 1/2" BELOW floor = flange extender required, not extra wax. Waxless is re-settable; wax is single-use.
Never use in-tank drop-in cleaner/bleach tablets: Kohler warns chlorine (calcium hypochlorite) damages tank fittings — the usual result is a degraded flapper and a running toilet — and VOIDS the warranty unless it's a Continuous Clean unit. If a running toilet is on tablets, that's the cause.
Open supply slowly, flush several times, and re-check for leaks over several DAYS (Kohler's explicit instruction).
