Best Smart Home for New Construction (2026)

Building a new home is the single best opportunity you’ll ever have to create a truly integrated smart home. When the walls are open, running wire is cheap. After drywall goes up, it becomes expensive, disruptive, and sometimes impossible.

The biggest mistake new home builders make with smart home technology is waiting. They figure they’ll “add smart stuff later” — not realizing that some of the most impactful infrastructure is 10x harder to retrofit. A $200 wire run during construction becomes a $2,000 project after the house is finished.

This guide covers exactly what to install during the build, what can easily wait until after move-in, and how to future-proof your new construction for smart home technology that doesn’t even exist yet.

The Golden Rule: Prewire Everything, Activate Later

You don’t need to buy every smart device today. But you absolutely need to run the wires now. Wire is cheap. Labor to open walls later is not. Even if you don’t plan to use a particular system for years, running the cable during construction costs a fraction of what it would cost as a retrofit.

Think of prewiring as buying options on future technology. The cable might sit unused for two years — but when you’re ready, everything is already in place.

What to Install During Construction

These are the items that are difficult, expensive, or impossible to add after your home is built.

1. CAT6A Ethernet to Every Room

Run at least two CAT6A ethernet drops to every room, including bedrooms, the kitchen, and the garage. Yes, WiFi is great — but wired connections are faster, more reliable, and essential for devices like security cameras, smart TVs, gaming consoles, and access points.

Why during build: Ethernet requires running cable through wall cavities and drilling through studs and top plates. After drywall, this means cutting holes, fishing wire, and patching.

Cost during build: $75–150 per drop (labor + materials) Cost to retrofit: $300–500 per drop

2. Conduit for Future Runs

Even if you don’t know what cables you’ll need in five years, install empty conduit (1” or 1.5” flexible PVC) between key locations — the attic to the basement, the media closet to the living room, and exterior walls to the central wiring closet. Conduit lets you pull new cables later without opening walls.

Why during build: Conduit needs to be placed before drywall. It’s cheap insurance.

Cost during build: $50–100 per run Cost to retrofit: Effectively impossible without opening walls

3. Recessed Outlets Behind TVs and Furniture

Install recessed power outlets and low-voltage brackets behind every planned TV location. These allow the TV to sit flush against the wall with no visible cable gap. Also consider furniture-height outlets behind nightstands and desks for clean charging setups.

Why during build: Electrical box placement is done before drywall. Adding outlets later requires cutting drywall, running new wire, and patching.

Cost during build: $25–50 per outlet (marginal cost during rough-in) Cost to retrofit: $200–350 per outlet

4. Smart Electrical Panel (Span or Leviton)

A smart panel like the Span Panel or Leviton Smart Load Center replaces your traditional breaker box and gives you per-circuit monitoring, remote control, and solar/battery integration from day one. It shows real-time energy usage by circuit and lets you remotely toggle circuits from your phone.

Why during build: The panel is installed during the electrical rough-in phase. Swapping out a traditional panel later means rewiring and a full day of electrician labor.

Cost during build: $4,000–6,000 installed (vs. $2,000 for a standard panel) Cost to retrofit: $6,000–10,000 (removal + rewiring + installation)

5. Central Wiring Closet / Structured Media Panel

Designate a climate-controlled closet or wall space as your “network hub.” All ethernet runs, coax, speaker wire, and camera cables terminate here. Install a small rack or structured media panel with adequate ventilation and power (dedicated circuit recommended).

Why during build: All low-voltage wires are routed here during rough-in. Retrofitting means re-routing cables through finished walls.

Cost during build: $500–1,500 (closet buildout + ventilation + power) Cost to retrofit: $2,000–5,000+

6. Outdoor Camera Mounting Points with PoE

Pre-mount junction boxes at key exterior locations (front door, driveway, back yard, garage, side gates) and run CAT6 cable to each — this gives you Power over Ethernet (PoE) capability for professional-grade cameras that don’t need batteries or separate power supplies.

Why during build: Exterior cable runs require going through siding, soffits, or masonry. After construction, this means drilling through finished exterior surfaces and potentially voiding warranties.

Cost during build: $100–200 per camera location Cost to retrofit: $400–800 per camera location

7. In-Wall and In-Ceiling Speaker Wiring

Run speaker wire (14/2 or 12/2 CL2-rated) to ceiling or wall locations for built-in speakers in the living room, kitchen, master bedroom, bathroom, and outdoor patio. Even if you use the cheapest speakers now, the wiring is permanent infrastructure.

Why during build: Speaker wire runs through wall cavities and ceilings. Retrofitting means cutting access holes and patching.

Cost during build: $50–100 per speaker location Cost to retrofit: $250–500 per speaker location

8. Motorized Shade Pockets and Wiring

If you want motorized shades in any room, the window framing needs recessed pockets (shade cassettes) and power (either hardwired 120V or low-voltage) run to the window header. Without the pocket, motorized shades stick out awkwardly from the wall.

Why during build: Shade pockets are built into the framing. Power wiring goes in before drywall.

Cost during build: $150–300 per window (pocket + wiring only) Cost to retrofit: $500–1,000+ per window (opening ceiling, re-framing, electrical)

What to Add After Move-In (Easy to Retrofit)

These items are designed to be installed in finished homes and don’t require construction-phase planning:

Smart locks — Replace existing deadbolts with no modification. See our best smart locks 2026 guide.
Smart thermostat — Replaces your thermostat on existing wiring. See our best smart thermostat guide.
Motion sensors and contact sensors — Battery-powered, stick anywhere
Smart plugs — Plug into existing outlets
Smart bulbs — Screw into existing fixtures. See our best smart bulbs guide.
WiFi mesh system — Sets up wirelessly (but benefits from wired backhaul to those ethernet drops you prewired)
Smart speakers and displays — Plug in anywhere
Robot vacuums — No installation needed

Working With Your Builder

Not all builders are familiar with smart home prewiring. Here’s how to make the process smooth:

Provide a written specification — Don’t assume verbal requests will be remembered. Create a document showing every wire run, outlet location, and conduit path.
Hire a low-voltage contractor — Most electricians handle high-voltage (120V/240V) but subcontract or skip low-voltage work. A dedicated low-voltage contractor specializes in ethernet, speaker wire, and camera cabling.
Walk the framing — Before drywall goes up, physically walk every room and verify wire placement. This is your last chance to catch mistakes.
Label everything — Ensure every cable is labeled at both ends. Future-you will be grateful when troubleshooting.
Document with photos — Photograph every wall cavity showing wire routes before drywall. This gives you a permanent record of where cables run.

Budget Planning: What Does Smart Prewiring Cost?

For a typical 2,500 sq ft new-build home, comprehensive smart home prewiring (ethernet, camera points, speaker locations, conduit, and a central wiring closet) typically adds $5,000–$15,000 to construction costs. A smart panel adds another $4,000–6,000.

This sounds significant, but consider: retrofitting the same infrastructure after the home is built would cost $20,000–40,000+ and never look as clean. Prewiring during construction delivers permanent value at a fraction of the retrofit price.

Choosing Your Ecosystem

Even during construction, think about which smart home ecosystem you’ll use. This affects decisions like voice assistant placement, hub requirements, and device compatibility.

Frequently Asked Questions

How much does smart home prewiring add to new construction costs?

For a typical home, comprehensive prewiring (ethernet to every room, camera locations, speaker wire, conduit, and a central wiring closet) adds $5,000–$15,000 depending on home size and number of runs. This is a fraction of what the same work would cost as a retrofit and adds resale value.

Should I install a smart panel or a traditional breaker panel?

If budget allows, install a smart panel (Span or Leviton). It provides per-circuit energy monitoring, remote circuit control, and seamless solar/battery integration. If budget is tight, install a traditional panel but run a dedicated ethernet cable to the panel location — some future smart panel upgrades can work with existing wiring.

Is CAT6 or CAT6A better for new construction?

Go with CAT6A. The cost difference per run is minimal ($5–10 more per drop), but CAT6A supports 10-gigabit speeds at full 100-meter distances. Future-proofing your home with CAT6A means your wiring won’t be the bottleneck for the next 15–20 years.

What if my builder says smart prewiring isn’t necessary?

Some builders are unfamiliar with low-voltage planning or don’t want the coordination effort. Insist on it — or hire your own low-voltage contractor to work alongside the builder’s electrician. The builder doesn’t need to understand why you want ethernet to every room; they just need to allow the work during framing and rough-in phases.

How many ethernet drops per room should I run?

At minimum, two per room (one for a device, one spare). For the living room and home office, consider four. For the central wiring closet, run extras to the attic and basement for future access point placement. Over-provisioning now costs almost nothing and prevents regrets later.

Final Thoughts

New construction is a once-in-a-lifetime opportunity to build smart home infrastructure the right way. Focus your construction-phase budget on the things you cannot easily add later — wiring, conduit, panels, and mounting points. Save the fun stuff (smart locks, sensors, voice assistants, automations) for after move-in when you can take your time choosing the right devices.

The walls will never be open again. Wire now, automate later.
