Key Takeaways
- Most NJ new builds budget 1.5%–4% of total construction cost for technology, depending on scope.
- Networking and structured wiring should be priced first since every other system depends on them.
- Wiring for future systems during construction costs a fraction of adding it after drywall.
- The biggest cost driver isn’t brand of equipment, it’s how many rooms and systems are included.
There Isn’t One Right Number, But There Is a Range
We get this question on almost every new construction project, and the honest answer is that it depends heavily on home size, finish level, and how much you want automated on day one versus simply wired for later. That said, across the homes we’ve worked on in Monmouth, Ocean, and Middlesex Counties, a reasonable planning range is 1.5% to 4% of total construction cost, covering networking, audio, video, lighting control, motorized shades, and security combined.
A 4,000 square foot home with a moderate finish level might land toward the lower end of that range if the owner only wants whole-home networking, security, and a few automated lighting zones. A larger luxury build with a dedicated theater, whole-home audio, integrated lighting throughout, and motorized shades on every window will land toward the higher end, and sometimes above it.
What Actually Drives the Cost
Square footage matters, but it’s not the biggest factor. The number of rooms getting active systems matters more. A 5,000 square foot home with networking and security only can cost less than a 3,000 square foot home with whole-home audio, lighting control, and a home theater in every common space.
Equipment tier plays a role too. There’s a meaningful difference between a builder-grade Wi-Fi setup with a couple of cameras and a fully designed network with managed switches, multiple access points, segmented traffic for cameras, and a properly built equipment rack. The second option costs more up front and performs dramatically better for the life of the home.
Labor and access also factor in. Wiring during framing, before insulation and drywall go up, is far cheaper per cable run than retrofitting the same wiring into a finished home. This is the single biggest reason we recommend bringing in a consultant before the walls close, even if you’re not ready to spend on every system immediately.
A Practical Way to Think About the Budget
We generally recommend separating the budget into two categories: infrastructure and experience. Infrastructure is the wiring, network equipment, and conduit, the things that are expensive to add later and nearly invisible once installed. Experience is the visible layer, the speakers you hear, the lighting scenes you see, the cameras you check on your phone.
Spend generously on infrastructure during construction, even if it means activating fewer systems on move-in day. You can always add a speaker, a camera, or a lighting keypad later. You can’t easily add a missing cable run once the walls are closed.
NJ Context
In Monmouth and Ocean County builds especially, we see homeowners stretch their technology budget further by prioritizing structured wiring and networking during construction, then phasing in audio, lighting, and security room by room over the first year or two of living in the home.
