Buying land in California
The average cost of land in California is $6,000 to $14,000 per acre, but costs vary significantly by location. An acre of land in the desert may cost only $3,000, while lots in major cities, coastal areas, or wine country often sell for more than $1 million.
A land survey costs $400 to $1,800 for new home construction. The surveyor will identify property boundaries and mark the proposed foundation borders and locations of utility lines.
Preparing the site
Before the builder can begin construction on your new home, they must prepare the site. Excavation costs $1,500 to $10,000 to level and grade the site before pouring the foundation. Costs may be higher if you're building in a rocky area that requires excavation with a jackhammer or blasting.
Foundation
Building a foundation costs $5 to $14 per square foot or $9,000 to $27,000 total, depending on whether it's a concrete slab, crawl space, or basement. Building on a sloped area—a common scenario in California—may also require concrete pillars, retaining walls, and other supports, increasing costs.
Coastal and lakefront homes may require a raised foundation to protect them from flooding. A pier and beam foundation costs $14,000 to $28,000.
Framing & roof
The cost to frame a house is $11 to $30 per square foot or $20,000 to $60,000 total for a typical house, including the roof trusses. Framing takes 30 to 60+ days, depending on the home's size and layout.
After framing, roof installation costs $6,000 to $18,000 total or around $3 to $6+ per square foot, depending on the material. Asphalt shingles are a popular roofing choice and fall within this price range. Tile and other premium roof materials cost $7 to $25+ per square foot with installation.
Siding
Your choice of exterior finishes also impacts construction costs. Siding costs $4 to $13 per square foot or $8,000 to $26,000 total installed, depending on the material and quality. Vinyl and aluminum siding are popular, affordable options. Premium materials like brick, stucco, and stone cost up to $45 per square foot.
Electrical
The average cost to wire a house is $4 to $9 per square foot or $8,000 to $18,000 total. Expect costs on the high end of that range if your house has a complex layout or requires a high-capacity electrical panel to power more appliances and devices.
Solar panels
The California Solar Mandate requires all new construction homes to have a solar panel system large enough to meet the home's annual electricity needs. The average cost of solar panels in California is $12,500 to $17,300 for a 5 kW system, before subtracting the 30% federal tax credit.
Plumbing & HVAC
New plumbing costs $8,000 to $12,000, depending on the pipe material and the home's layout. Rough-in plumbing for a new house includes installing water supply lines, drain lines, pipes, connection, sand vents. Plumbers charge an additional $450 to $1,800 per fixture to install sinks, toilets, bathtubs, and other fixtures.
A new HVAC system with ductwork costs $7,000 to $16,000, depending on the home size and the system type, size, and brand.
Interior finishing & fixtures
Interior finishes include flooring, cabinets, countertops, painting or wallpaper, lighting, and more. Fixtures and finishes make up a large portion of the total construction cost, and prices can vary widely depending on the quality. Keep these items in mind when planning your build:
Flooring costs $4 to $15 per square foot on average or $8,000 to $30,000 total with installation.
Cabinets cost $150 to $500 per linear foot or $4,500 to $15,000+ total with installation, depending on if they're stock or custom cabinets.
Countertops cost $50 to $150 per square foot installed, depending on the material.
Lighting fixtures cost $70 to $400 each with installation.
Drywall installation costs $1.50 to $3.50 per square foot or about $8,000 to $30,000 total for an average house, depending on the interior layout.
Painting costs $1 to $3 per square foot of wall or ceiling surface.
Appliances
Appliances cost $200 to $2,300 each on average, depending on the brand, model, and features. Prices for high-end ovens, ranges, and refrigerators can reach $5,000+ each.
A kitchen appliance package with a basic fridge, range, dishwasher, and microwave costs $2,100 to $5,400. A package featuring high-end appliances costs $5,400 to $13,000+.
A washer and dryer costs $1,000 to $2,300 per set.
Labor costs to build a house in California
Your builder will act as a general contractor to coordinate your entire project, order materials, manage the subcontractors, and ensure construction stays on schedule. A general contractor charges 10% to 20% of the construction budget, and most builders include this fee in their total estimate for the project.
Your builder will typically hire and manage all the subcontractors involved in the project.
