Building a New Home in Nova Scotia? Here's What Your Electrician Should Be Planning For

By Wadden Electric • 9 min read

You're building a custom home in Halifax, Dartmouth, or somewhere along the South Shore. You've picked your architect. You've got your general contractor. The electrical sub is booked. But here's the question most homeowners don't ask until it's too late: is your electrician planning for the house you'll want in 5 years — or just the house you're building today?

The $20,000 Mistake

We get calls every month from homeowners who built 3-5 years ago and now want to add a smart home system. The conversation always goes the same way:

"We want whole-home audio." Great — but there's no speaker wire in the ceilings. Retrofit cost: $3,000-8,000 just for wire pulls, plus drywall repair and paint.

"We want security cameras." Perfect — but there's no Cat6 cable home-run to the camera locations. Retrofit: $2,000-5,000, plus exterior penetrations and siding work.

"We want motorized shades." Love it — but there's no power at the window headers. Retrofit: $1,500-4,000 per room to fish wire through finished walls.

The total retrofit bill for a basic smart home package: $15,000-25,000 in labor and remediation. The cost to prewire all of this during rough-in? $3,000-6,000. Same result. Fraction of the cost.

The Prewire Checklist

Here's what a smart-home-ready electrical rough-in should include — even if you're not installing the smart home systems right now:

Structured Cabling

• Cat6A Ethernet to every TV location, every bedroom, and the home office
• Cat6A to ceiling-mount locations for wireless access points (3-4 locations for a typical 3,500 sq ft home)
• Cat6A home runs to every exterior camera location (eaves, garage, front door, back yard)
• All Cat6A cables home-run to a central network rack location (utility room, basement, or dedicated closet)

Audio Pre-Wire

• 16/2 speaker wire to ceiling locations in kitchen, living room, master bedroom, patio, and any room where you'd ever want music
• Conduit to the home theater location for future speaker wire, HDMI, and power
• All speaker wire home-run to the rack location

Lighting Control

• Dedicated lighting circuits separated from receptacle circuits — this allows a Lutron system to control all lights independently
• Neutral wire in every switch box (required by code in the CEC 26th Edition, but verify your electrician is actually pulling it)
• Power at window headers for motorized shading — a single 14/2 cable to each window group

Power & Panels

• 200A service minimum for any home over 2,500 sq ft with electric range, dryer, and future EV charger
• Dedicated 20A circuit to the network rack location
• Dedicated circuit for any future EV charger (even if you're not buying an EV today — the conduit and breaker space cost almost nothing during construction)
• Panel capacity for Savant smart breakers if energy monitoring is a future interest

The Conversation to Have With Your Builder

The biggest problem isn't that builders don't want to plan for smart home infrastructure. It's that most electricians don't know what to plan for. They wire houses the way they always have — which was fine in 2005 but leaves a 2026 custom build unprepared for the systems today's homeowners actually want.

The solution is simple: bring your smart home integrator into the conversation during design, before the first wall goes up. At Wadden Electric, we provide complete prewire specifications that your GC and electrician can follow. If we're the electrical sub, it's all coordinated under one scope.

That's the advantage of working with a company that holds both an electrical licence and smart home integration expertise. One team thinks about the whole picture — not just what's on the electrical drawings.
