The best smart home features for a new build split into two very
different shopping lists: infrastructure you must decide on
before drywall, and devices you should mostly buy
after closing — usually for less than the builder’s
package price. Confusing the two lists is the most expensive mistake in
this category. Here’s how to divide it.
The Before-Drywall List
(Decide Now)
These are framing-stage decisions. Each one is cheap while the walls
are open and painful after:
- Structured wiring — Cat6 to TVs, offices, and
ceiling access points; conduit behind media walls; PoE runs for cameras
and the doorbell. This is the backbone everything else rides on. We’ve
published a full room-by-room plan with drop counts and 2026 costs in
our smart home wiring guide — if you read one companion piece, read that
one. - Neutral wires and deep boxes at every switch —
required for virtually all smart switches; standard in new construction
under current code, but confirm it, and ask for deep boxes at multi-gang
locations. - An EV-ready garage circuit — a dedicated 240V/50A
circuit costs a few hundred dollars now and up to ten times that as a
retrofit. Full specs and code details in our EV rough-in guide. - Motorized shade wiring at the great-room and
primary-bedroom windows, even if shades come later. - A 200A electrical panel with spare breaker spaces —
the quiet enabler of the EV charger, the future solar array, and the
induction range.
That’s the entire “builder conversation” for smart homes. Everything
below is a purchase, not a construction decision.
The
Buy-It-Yourself List (Best Devices for a New Build, 2026)
A smart lock. The single highest-satisfaction device
in the category — codes for family and guests, no more key handoffs.
Current picks run from the Schlage Encode Plus (~$300 all-arounder) to
Matter-over-Thread values like the Aqara U300 (~$180) and 2026’s
hands-free UWB flagships. We maintain a full roundup with prices in our
smart locks guide; your pre-bored new-construction door makes any of
them a 20-minute install.
A video doorbell on the PoE run you wired. A wired
doorbell on your own recorder means no subscription and no battery
charging — the payoff of that one Cat6 run to the front door.
A smart thermostat ($130–$250). Verify compatibility
with your specific HVAC system — especially heat pumps with auxiliary
heat stages — and check your utility for enrollment rebates, which
frequently cover most of the cost.
Smart switches in main living areas — not smart
bulbs. A switch controls the fixture for every bulb inside it
and works for every guest who touches the wall. Bulbs are for lamps and
color moments. Eight to twelve switches ($40–$60 each) in the kitchen,
great room, exterior, and hallways cover the rooms where automation
actually gets used.
Two or three PoE cameras on the runs you pre-wired —
driveway, front approach, backyard. Local recording, no cloud fees, no
batteries to climb a ladder for.
Speakers/displays for your ecosystem — the
room-presence layer for voice control and intercom. Buy these last;
they’re the most replaceable part of the stack.
For what all of this should cost at each budget level — from a $3,500
starter build to full Control4/Crestron integration — see our whole-home
automation budget guide.
Skip the Builder’s Device
Package
Builders are good at wiring and framing-stage infrastructure; their
device packages are typically last-generation hardware at a
healthy markup, locked to whatever platform their vendor sells. Take the
pre-wire (often fairly priced at $1,500–$4,000), decline the gadget
bundle, and spend the same money on current hardware the week you move
in.
Pick the Ecosystem Once
Before buying anything from the second list, decide the platform
question: it should almost always be whichever ecosystem your
household’s phones and speakers already lean toward. Then buy
Matter-certified devices wherever possible — Matter
support has matured to the point (the current spec even covers cameras)
that it’s a reasonable requirement rather than a nice-to-have, and it
keeps every device portable if you switch platforms later.
The Bottom Line
Wire generously, buy devices frugally. The features that make a new
build feel genuinely smart in 2026 are a lock, a wired doorbell, a
thermostat, switches in the main rooms, and a couple of cameras — maybe
$2,000 of hardware — sitting on a wiring plan the builder ran for
another $2,000 while the walls were open. Infrastructure is forever;
gadgets are replaceable. Spend accordingly.
