How Much Does Smart Home Integration Add to a GTA Renovation in 2026?
We have been doing renovations in and around Toronto for over 50 years. When I first started, “smart home” meant a programmable thermostat — one of those beige Honeywell boxes that you had to set manually every season. Now I am getting this question almost every week from homeowners doing kitchen or basement renos: how much does all this smart home stuff actually add to the budget, and is it worth doing during the renovation or easier to bolt on later?
So here is the honest breakdown from what we are actually seeing on jobs right now.
What Falls Under “Smart Home Integration”
This is where people get confused. The category is enormous and the price range is wild. At the low end you have smart plugs, a Wi-Fi thermostat, and a video doorbell. Total cost: a few hundred dollars and you install it yourself. At the high end you are talking about a Lutron Caseta or Control4 system wired into the electrical, motorized blinds, in-wall touchscreen panels, and a dedicated rack in a utility room. That is a very different conversation.
For most Toronto-area homeowners doing a mid-range renovation in 2026, the sweet spot we see is somewhere in the middle:
- Structured wiring rough-in: $800 - $2,000 depending on home size. This is CAT6 ethernet run to every room during the reno while the walls are open. You do not need to use it all immediately but you cannot easily add it later without opening walls.
- Smart thermostat and HVAC integration: $400 - $1,200 installed, depending on your HVAC setup. Worth doing if you are touching the mechanical anyway.
- Lighting control (partial): $1,500 - $5,000+ for a zone or two of dimmer-compatible LED and smart switches. The wiring is the labour-intensive part.
- Security and camera rough-in: $600 - $1,500 to have conduit and low-voltage wiring placed during the reno for cameras and sensors.
Total realistic add-on for a mid-range kitchen or full basement reno: $3,000 - $8,000 if you are doing it properly and proactively, not reactively.
What I Tell Homeowners: Do the Rough-In, Delay the Devices
The best advice I give is this: do the infrastructure now (wiring, conduit, panel, in-wall boxes) and buy the devices later. Technology changes fast. The ethernet you pull today will still be useful in 15 years. The specific smart switch brand you commit to today may not be supported in five.
This is especially true for lighting. If you are renovating, spend the extra on compatible dimmers and neutral-wire switches throughout. That is a small cost — maybe $30 per switch more than a basic switch — but it means you can add smart controls without rewiring later.
Where It Is Actually Worth the Premium
A few spots where smart integration pays off clearly in the GTA market:
Heating and cooling. Ontario energy costs are significant and a properly zoned smart HVAC setup genuinely pays back over time. Not just in utility savings but in comfort — especially for two-storey homes where the upstairs is always 4 degrees warmer.
Outdoor lighting and security. For Toronto homes with detached garages, side laneways, or larger lots, smart exterior lighting and camera integration is increasingly what buyers expect. We are seeing this referenced in real estate listings now.
Basement suites. If you are finishing a basement for rental or for family, a separately controllable smart thermostat and its own electrical sub-panel rough-in is worth every dollar.
What I Would Skip (For Most People)
Motorized blinds unless you have a very specific reason. Full-house audio wired into the walls unless you are a serious audiophile. Whole-house water monitors are interesting but still early-adoption pricing.
I am curious what folks here are actually doing on their renos. Are you planning smart home as part of the build, or adding it after? And if you hired a contractor to do it — what did it end up costing?
We do this kind of rough-in work regularly on kitchen and bathroom renos across the GTA — happy to answer questions about what makes sense to integrate at the trade stage versus leave for later.
