What Should I Pre-Wire for Smart Home Tech When Building a House?

The cheapest smart-home upgrade you will ever buy is the wire that goes in before drywall. Once insulation and sheetrock close the walls, every missed cable becomes fishing, patching, and compromise. For new construction around Milwaukee and Waukesha, a clear pre-wire plan — coordinated with your builder and electrician — keeps every future option open even if you do not buy every device on day one.

When pre-wire happens

The window is short: after framing and rough electrical, before insulation and drywall. That is when a low-voltage team walks the house, marks locations, pulls cable, labels both ends, and leaves a map. Miss that window and you can still add wireless gear later — but you lose the clean, reliable foundation that makes a professional system feel invisible.

You do not have to install every keypad, speaker, and camera at trim-out. You do want the pathways in place so adding them later is a device and programming visit, not a remodel.

Start with a conditioned equipment location

Pick a central, climate-controlled closet or room for the network rack, control processors, audio amplifiers, and shade power supplies. Avoid attics and unconditioned garages when you can — heat and cold shorten equipment life and make service harder.

That location should include:

• Dedicated power (and ideally a UPS later)

• Ventilation and enough wall or rack depth to grow

• Conduit pathways toward main TV walls and outdoor zones

• Space for the ISP handoff (fiber/cable entry) to land cleanly

Everything else home-runs back here. Labeling both ends of every cable is not optional; it is how trim-out and future service stay sane.

Network and Wi-Fi (do this even if nothing else)

A strong wired network is the backbone of modern homes — streaming, cameras, access points, touchscreens, and many control devices all prefer Ethernet.

Pull Cat6 (or Cat6A) to:

• Every planned TV location

• Home offices and desks (two or more drops where people work)

• Ceiling locations for Wi-Fi access points on each floor

• Camera and door-station positions

• Touchscreen or in-wall controller spots (kitchen, entry, primary suite)

• Outdoor AP or patio TV locations, in conduit where exposed

Ceiling access points beat stuffing a consumer router in a basement corner. Plan coverage for the finished floor plan, including thicker Wisconsin exterior walls and the patio you will actually use in summer.

TV and video locations

At each wall-mounted TV:

• In-wall power behind the display

• Cat6 for network and control

• Conduit (often called “smurf tube”) from the TV wall back toward the equipment location so HDMI, fiber HDMI, or future cable can be swapped without opening walls

Blocking in the studs for the mount saves a callback. Long HDMI runs have limits; conduit preserves options when formats change.

Distributed audio and home theater

Pull speaker wire from each speaker location back to the rack — typically in-wall-rated 16/2 or 14/2, with heavier gauge for longer runs and subwoofers. Plan:

• Stereo pairs in living spaces and primary suites

• Surround and height channels if a theater or media room is on the plans

• Outdoor speaker routes to patio, pool, or landscape zones using outdoor-rated or direct-burial cable as needed

• Volume keypad or local control locations if the design calls for them

You can leave speakers for phase two. Empty wire behind drywall is cheap insurance.

Lighting control and keypads

Agree keypad and dimmer locations with the electrician early. Professional lighting platforms need:

• Neutral wires in switch boxes (required or strongly preferred for many smart dimmers)

• Deeper boxes where multi-button keypads will land

• A clear plan for which loads are on which keypad so the wall does not become a sea of mismatched switches

Whether you end up on Lutron, Control4 lighting, or both, the rough-in decisions happen now.

Motorized shades

If shades are likely — and in glass-heavy new builds they usually are — pre-wire window headers for power or low-voltage shade cable, and frame recessed shade pockets where the architecture calls for a clean ceiling line. Retrofitting wire after drywall is possible with battery shades, but hardwired architectural shades are cleaner when the rough-in is done right.

Cameras, door stations, and the exterior

Exterior low voltage is easy to forget and expensive to add later:

• Cat6 to camera corners, garage, and entry

• Door station / video doorbell pathway at the front door

• Speaker wire and Cat6 for outdoor audio and patio displays

• Conduit for anything that crosses grade, decks, or hardscape

Weatherproof boxes and drip loops belong in the plan, not as an afterthought in March mud.

Climate and miscellaneous

Coordinate thermostat wire with a common (C) wire for smart thermostats. Note future gate, garage, or outbuilding pathways if the lot will grow. A spare conduit from the equipment closet toward the attic or main chase is one of the highest-value “empty” things you can install.

A practical room-by-room snapshot

Area	Typical pre-wire
Living / family	Cat6 + conduit + power at TV; speaker wire; shade wire at glass
Kitchen	Cat6 for touchscreen; speaker wire; keypad neutrals
Primary suite	TV drops; speakers; shade wire; bedside keypad locations
Office	Multiple Cat6 drops; AP nearby
Each floor	Ceiling AP Cat6
Exterior	Cameras, door station, outdoor speakers/TV, outdoor AP

Exact counts depend on the house. The table is a starting conversation with your integrator and builder — not a one-size sketch.

FAQ

Can I pre-wire now and buy the smart home system later?

Yes. That is often the smartest path. Wire and document thoroughly, then add controllers, keypads, speakers, and cameras in phases after you move in.

Is Cat5e enough?

Cat5e can work for many devices today. For a new build meant to last, Cat6 or Cat6A is the better default — more headroom for access points, cameras, and future speeds.

What if I am not sure where the TVs will go?

Mark the likely walls with your integrator during the framing walk. Extra Cat6 and a conduit stub are inexpensive compared with guessing wrong after paint.

Do wireless systems mean I can skip wire?

Wireless lighting and battery shades help in finished homes. In new construction, wire still wins for networks, cameras, speakers, hardwired shades, and clean TV walls. Wireless should fill gaps — not replace the backbone.

Wire once, decide later

Pre-wire is not about buying every gadget on the market. It is about giving a new Wisconsin home a backbone: network, audio, video pathways, lighting-ready boxes, shade power, and exterior drops — labeled and mapped — so the house can grow with you. Bring your integrator in while the studs are still open.
