How Do I Plan Electrical for a New Construction Home?

Electrical Q&A
How Do I Plan Electrical for a New Construction Home?

Electrical planning for a new build is one of the highest-leverage decisions in the entire construction process. Every wire and box is easier to install now than to retrofit later, so a well-planned system pays dividends for the life of the home. Here is how to think about it, from the licensed electricians at EZSMART, serving Toronto and the GTA.

Start With the Main Panel Size

For new construction, 200 amp service is now the standard, since it supports current electrical demand including central air conditioning, an EV charger, electric heating, and future additions. Some larger homes benefit from 400 amp service. Modern panels from manufacturers like Eaton and Square D are standard.

Room-by-Room Considerations

  • Kitchen: Multiple dedicated circuits, GFCI protection, under-cabinet lighting, island outlets
  • Bathrooms: Dedicated GFCI-protected circuits, wet-rated fixtures, heated floors if desired
  • Bedrooms: Sufficient outlets for modern device density, ceiling fan wiring even if fans not immediately installed
  • Living areas: Enough outlets for entertainment centers, holiday lighting outlets, exterior outlets
  • Garage: EV charger circuit or at minimum wiring stubbed in for future installation, workshop circuits, GFCI-protected outlets
  • Outdoor spaces: Weatherproof outlets, landscape lighting circuits, deck or patio lighting

Future-Proofing

Since retrofit costs are so much higher than initial install, new builds are the ideal time to include:

  • EV charger circuit or at least conduit stubbed to the garage
  • Data wiring (Cat 6 or better) to every room
  • Solar-ready wiring even if not installing immediately
  • Smart home hub location with adequate power and network
  • Whole-home surge protection at the panel
  • Standby generator interlock if a generator is planned

The Permit and Inspection Process

New construction electrical requires both rough-in and finish inspections through the Electrical Safety Authority. Your licensed electrical contractor handles this alongside your general contractor.

Frequently Asked Questions

Do all new builds use 200 amp service?
Most new residential builds do, though very large homes or homes with heavy planned load may benefit from 400 amp service.

Is it worth adding data wiring throughout even in the WiFi era?
Yes, wired connections are still more reliable for heavy use, and adding data cable during construction is much cheaper than retrofitting later.

Can I choose my own electrician for a new build?
Typically your builder has an electrical contractor, though homeowners with custom builds often coordinate their own electrician directly.
