Kitchen Renovation Electrical: 9 Decisions to Make Before the Walls Close

By the time most kitchen renovations reach us, the cabinets are ordered, the tile is picked, and the appliances have a delivery date. The electrical plan is the one thing nobody wrote down. That's how you end up at rough inspection with an island that has no receptacle, a coffee station sharing a circuit with the microwave, and a backsplash outlet dead center in a tile that was supposed to stay uncut.

All of it is cheap on paper and expensive once the walls close. Here are the nine decisions to settle first.

The code edition decides your island

NYC and the rest of New York State are not on the same edition of the National Electrical Code, and the gap lands in the middle of your kitchen. The 2025 NYC Electrical Code, enacted by Local Law 128 of 2024, governs work filed on or after December 21, 2025 and is built on the 2020 NEC plus NYC amendments. Outside the five boroughs, the 2025 NYS Uniform Code adopted the 2023 NEC effective December 31, 2025.

That matters because under the 2020 NEC, 210.52(C)(2) requires island and peninsula countertop receptacles. The 2023 NEC made them optional — skip one upstate and you just leave provisions to add it later. A contractor who mostly works in Nassau, Westchester, or the Hudson Valley may tell you in good faith that the island outlet is no longer required. In the five boroughs, it still is.

• 1. Island receptacles. At least one receptacle for the first 9 square feet of island countertop, plus one more for each additional 18 square feet. Where it goes is a millwork decision: anything set into the counter has to be an assembly listed for countertop use — no face-up standard device. Settle it before the island is fabricated.
• 2. Peninsula receptacles. At least one receptacle within 2 feet of the outer end — the peninsula is measured from the wall it connects to. Your cabinet shop needs that in the drawing now, not after delivery.

Two countertop circuits is the floor, not the plan

• 3. How many small-appliance circuits. NEC 210.11(C)(1) requires a minimum of two 20-amp small-appliance branch circuits for the kitchen countertop receptacles, and those circuits may serve no other outlets. If your morning is an espresso machine, a toaster oven, and an air fryer on one run of counter, ask for more — a circuit is trivial now, a demolition job later.
• 4. Which appliances get a dedicated circuit. Budget for the range or cooktop and wall oven (240-volt, sized to the nameplate), plus dishwasher, disposal, built-in microwave, refrigerator, and hood. The NEC lets the refrigerator sit on its own 15-amp-or-larger individual branch circuit instead of eating a countertop circuit. Manufacturer instructions are enforceable under NEC 110.3(B), so the appliance spec sheets belong in your electrician's hands before rough-in.
• 5. Whether the panel can take it. Count breaker spaces and service capacity before demo — plenty of prewar Brooklyn homes still run 100-amp service sized for a very different kitchen. NYC's amendments add load you may not expect: every living room, dining room, and bedroom needs its own air-conditioner receptacle circuit, counted at 1,500 VA minimum whether or not an A/C is installed. If the calc comes up short, plan the panel upgrade early — a service increase means coordinating with Con Edison, which won't bend around your cabinet install date.

Placement the cabinet and tile shops need in writing

• 6. Countertop receptacle spacing. NEC 210.52(C)(1) puts receptacles so no point along the countertop wall line is more than 24 inches horizontally from one — in practice, roughly every 4 feet. Work out height and orientation against the backsplash tile layout, or the tile setter makes that call with a saw.
• 7. Everything switched, dimmed, or hidden. Under-cabinet lighting needs a switch leg and a home for the driver. Same for in-cabinet and toe-kick lighting, a charging drawer, any outlet inside a cabinet — each is a wire that must exist before drywall.

Protection, and the paperwork behind it

• 8. GFCI, including the dishwasher. Kitchen countertop receptacles require GFCI protection per NEC 210.8(A). Less well known: so does the dishwasher — under the 2020 NEC, 210.8(D) and 422.5(A) put it on the GFCI list, hardwired or cord-and-plug. That catches remodels where the old dishwasher circuit gets reused as-is.
• 9. Who files, and under which code. In NYC there's no homeowner self-permit for electrical work — only a DOB-licensed Master Electrician or Special Electrician can file it. Timing matters too: per DOB Buildings Bulletin 2024-008, work filed before December 21, 2025 may still run under the 2011 NYC Electrical Code, though applicants could elect the newer one. If your job was filed in 2025 and is only now reaching rough, ask which edition applies.

Opening a prewar kitchen often exposes cloth-insulated conductors, ungrounded circuits, or old BX that can't carry what you're planning. Sometimes the honest answer is partial rewiring while the walls are open — the cheapest that work will ever be. In a co-op or condo, expect an alteration agreement and board approval on top of the filing.

Get it on paper before demo

The kitchen electrical plan should exist before the first cabinet is ordered: circuit list, appliance schedule, device locations on the elevations. Chazon Electric is licensed and insured, works across the five boroughs, and can review your plans and handle the DOB filing. Call (718) 924-8062 before the walls close.
