Does smart home tech help resale value?
An honest look at smart home tech and resale: wiring and network infrastructure add value, gadgets mostly do not, and documentation matters.
Every summer I get a version of this question, usually from someone either planning a renovation or getting a house ready to list: "will smart home stuff help the sale price?" People expect a tech consultant to say yes. My honest answer is: the boring parts help, the exciting parts mostly do not, and the difference is worth understanding before you spend money.
Infrastructure holds value, gadgets do not
Buyers, and more importantly home inspectors and agents, respond to things that are permanent, universal, and hard to retrofit. Structured wiring runs through walls. Conduit that makes future changes cheap. A tidy central panel where the connections land. Hardwired network drops in the office and behind the TV. Good Wi-Fi coverage that comes from properly placed wired access points rather than a stack of extenders.
None of that depends on which ecosystem the buyer prefers. Ethernet in the wall works the same whether the next owner is an Apple household or an Android one, a tinkerer or someone who just wants Netflix to work. That neutrality is exactly why it holds value. It is the same logic I laid out in the renovation conduit rule: the cheap, permanent pathways are the investment, and everything that plugs into them is temporary.
Gadgets are the opposite. A voice assistant, a smart bulb, an app-controlled blind: these are consumer electronics, and consumer electronics depreciate like consumer electronics. Worse, they are opinionated. Your carefully built ecosystem may read to a buyer as a pile of someone else's accounts and someone else's problems.
What buyers actually pay attention to
In my experience the smart features that register positively in a sale are the ones that overlap with traditional home value: a smart thermostat (reads as energy efficiency), video doorbells and cameras (read as security), smart locks (convenience, though some buyers will replace them on principle, and fair enough), and irrigation or leak-detection controls (read as protecting the house itself).
Notice the pattern. Each of those is a better version of something houses already had. A thermostat is a thermostat. Nobody is paying more for the house because the basement lights can turn purple.
And weak infrastructure actively hurts. A buyer touring a large house who watches their phone drop off Wi-Fi in the back bedroom will remember it. Dead spots are a visible defect now, the way a weak shower used to be. If the house has coverage problems, fixing them properly, with wired access points rather than gadgets, is money better spent than any automation. I wrote about how that is done in wiring for Wi-Fi.
The handover problem nobody plans for
Here is where smart homes genuinely go wrong at sale time. Half the "smart" value of a house is locked inside the seller's accounts: the app logins, the hub configuration, the automations, the camera history. When the seller's accounts leave, a poorly documented smart home becomes a house full of devices in unknown states, some of which may still be talking to the previous owner's phone.
If you are selling, do the next owner and your own liability a favour. Factory-reset every device that stays. Remove them all from your accounts, and check the manufacturer's account page to confirm nothing still lists the house. Leave a one-page sheet: what stays, what it is, where the hubs are, and the Wi-Fi details for anything that needs reconnecting. Label the panel where the wiring terminates.
That single page of documentation does more for a smooth sale than another thousand dollars of devices would.
What stays and what goes: decide early
In Ontario, the default expectation is that anything attached to the house stays (fixtures) and anything you can unplug and carry goes (chattels), but smart home gear blurs the line constantly. Is a doorbell wired to the transformer a fixture? Usually. Is the hub in the closet that makes it work a fixture? Debatable. Sort this out with your agent in the listing paperwork, explicitly, device by device, rather than during closing.
My general advice: leave everything hardwired, take everything with a subscription tied to you personally, and put the difference in writing.
Where I land
Spend renovation money on wiring, conduit, and network coverage; that is the smart home investment with resale value, and it happens to be the foundation any future owner's gadgets will need anyway. Buy gadgets because they make your life better while you live there, and count their resale value as roughly zero.
If you are planning a renovation or a sale and want an hour to sort your house into "adds value", "neutral", and "reset and document" columns, that is what my planning sessions are for. I sell no devices, so I have no reason to talk you into any.
