Kitchens have more specific code requirements than almost any other room in the house. Here’s the mandatory list: two 20A small appliance circuits (SAC) for countertop receptacles (210.11(C)(1)), a dedicated 20A circuit for the refrigerator (strongly recommended), a dedicated circuit for the dishwasher, a dedicated circuit for the garbage disposal (or they can share if the nameplate allows), and GFCI protection on all countertop receptacles within 6 feet of a sink.
The small appliance circuits are what trips people up most. Both SACs must serve only the kitchen, pantry, breakfast room, and dining room (210.52(B)(1)). They can’t feed anything else. And you need a minimum of two circuits, not two outlets. Both can share a neutral as a MWBC on a two-pole breaker if you’re tight on panel space.
For a full kitchen remodel, I’m typically running: 2x 20A SAC, 1x 20A refrigerator, 1x 20A dishwasher, 1x 20A disposal, 1x dedicated for microwave, 1x range/oven (usually 50A, check the nameplate), and lighting on its own circuit. That’s 7-8 circuits minimum for a full kitchen. Quote accordingly.
