Kitchen expansions, bathroom gut jobs, and room additions all increase electrical demand. Planning power needs before drywall goes up avoids overloaded panels, failed inspections, and expensive rework.
Start with a load assessment
Have a licensed electrician review your main panel capacity (amps), available breaker spaces, and current load. Remodels often add:
- Dedicated 20-amp small-appliance circuits for kitchens
- GFCI and AFCI protection in kitchens, baths, garages, and bedrooms
- 240V circuits for ranges, dryers, heat pumps, or EV chargers
- Lighting layers—recessed cans, under-cabinet LEDs, and exterior fixtures
Common remodel electrical upgrades
- Panel upgrade (100A to 200A): Needed when adding major appliances or an ADU.
- Subpanel: Feeds a distant addition when running many circuits from one homerun is impractical.
- New grounding and bonding: Older homes may need updates to meet current code during permitted work.
- Smart switches and low-voltage prewire: Plan before insulation—much cheaper than fishing wire later.
Room-by-room planning tips
- Kitchen: Map counter outlets every 4 feet, island power, dishwasher/disposal circuits, and ventilation.
- Bathroom: Separate lighting and exhaust fan circuits; GFCI within required distances of sinks.
- Home office: Dedicated circuits reduce tripped breakers from printers, monitors, and space heaters.
- Outdoor living: Weather-rated outlets, landscape lighting transformers, and pool or hot tub feeds need early layout.
Permits and inspections
Most structural and electrical remodel work requires permits. Inspections typically happen at rough-in (before drywall) and final. Using unpermitted work can block refinancing, insurance claims, or future sales. Your electrician should coordinate inspection scheduling with the general contractor.
Coordinate timing with other trades
- Finalize lighting and outlet locations on plans before framing changes.
- Rough-in electrical after framing and HVAC ducts, before insulation.
- Confirm appliance specs early—induction ranges and tankless water heaters affect wire size and breaker ratings.
- Leave access panels for tubs, shower valves, and any equipment needing service.
Budget and contingency
Electrical often runs 10–15% of a major remodel budget, more if the panel is upgraded or the home has knob-and-tube or aluminum wiring that must be addressed in opened walls. Hold contingency for unknown conditions discovered during demolition.
When to call an electrician early
- Your panel is full, rusted, or still uses fuses.
- You are adding square footage or an HVAC system type change.
- Plans include EV charging, solar, or battery backup.
- Insurance or inspector flagged wiring issues in the existing home.
Final takeaway
Bring an electrician into the design phase—not after cabinets are ordered. A load calculation, panel plan, and permit strategy upfront keep your remodel on schedule and ensure the finished space has safe, code-compliant power for how you actually live.
