Buying land
Before construction can begin, you'll need to purchase a lot suitable for building. The cost of land in New Jersey starts at around $9,000 per acre in rural areas, but prices can reach $100,000 to $350,000 per acre in highly desirable locations.
A new construction land survey costs $400 to $1,800 on average and includes marking property boundaries, utilities, and foundations.
Site prep
Your land will need to be prepared before builders can install the foundation. The cost of excavation ranges from $1,500 to $10,000 on average to level and grade a new home site. However, costs can quickly reach $20,000 or more for land with rough terrain, excessive clay, rocky soil, or large boulders.
Foundation
New foundation installation costs $5 to $14 per square foot or $10,000 to $40,000 total on average, depending on if it's a concrete slab, crawl space, or basement.
Many new homes in New Jersey are built on a slab-on-grade foundation, one of the most affordable types. However, if you're planning to build in a coastal location, consider an elevated foundation on piles, piers, or posts to reduce the risk of flooding.
Framing
The cost to frame a house ranges from $11 to $30 per square foot for labor and materials, or $22,000 to $78,000 total for a typical New Jersey house, including the roof trusses. Framing makes up a large chunk of the total construction cost and takes 30 to 60+ days, depending on your home's size and layout.
Roof
Roof installation costs $3 to $6 per square foot on average, depending on the material. Asphalt shingles are the most common choice in New Jersey due to their affordability and durability. Tile and metal roofs are also popular choices but come at a higher cost of $7 to $25+ per square foot installed.
Siding
New house siding costs $4 to $13 per square foot or $8,000 to $35,000 total with installation, depending on the material. Popular siding choices for New Jersey homes include:
Fiber cement siding
Vinyl siding
Aluminum siding
Cedar wood siding
Electrical
Wiring a new house costs $4 to $9 per square foot or $9,000 to $24,000 total on average. Expect to pay on the higher end of that range if your house features a complex layout or you need a more powerful electrical service panel to handle all the systems, appliances, and devices.
Choose an electric panel with a higher capacity if you plan to install an electric vehicle (EV) charging station in your garage.
Plumbing
Rough-in plumbing costs $8,500 to $22,000, depending on the home's layout and the pipe material used. Rough-in plumbing includes installing pipes, connections, water supply lines, drain lines, and vents. Plumbers charge an extra $450 to $1,800 per fixture to install sinks, toilets, bathtubs, and showers.
HVAC
More than 93% of homes in New Jersey have air conditioning, with around 80% having central air instead of relying on window AC units. Installing central air conditioning and ductwork costs $8,000 to $20,000, depending on the home's size and the HVAC system type, size, and brand.
Interior finishing & fixtures
The total cost for interior finishes and fixtures can range from $50,000 to $250,000+, depending on the materials and quality. This category makes up a large chunk of the total building cost and includes cabinets, countertops, flooring, lighting, painting, and more.
Keep these items in mind when budgeting for your new home:
Kitchen cabinets cost$150 to $500 per linear foot with installation.
Countertops cost $50 to $150 per square foot installed.

A kitchen appliance package featuring a basic refrigerator, oven/range, dishwasher, and microwave costs $2,100 to $5,400.
