California remains the most populated state, with just over 39 million people. Because of supply and demand, land and property tend to have a low supply with high demand. This will drive up prices and contribute to why some neighborhoods just one street across from another will have different prices.

Labor Cost to Build a House in California

Labor costs won't be going to any one contractor. Building a home requires quite a large team, ranging from hiring a nearby construction management company down to the team needed to pave a driveway or install your electrical wiring. Services will not always be in flat numbers and may cost a percentage of the home instead.

Consider these fees:

Construction Manager

The average construction manager for homes under $10,000,000 will charge 5% to 15% of the project total. The project construction manager (also known as general contractors) will likely be in charge of helping your dream home come to fruition. Most will charge on a percentage basis rather than a fee basis.


Framing builds the internal structure of the home before any walls, wires, or pipes go up. It'll cost anywhere from $2,120 to $8,650, but fluctuating lumber prices could drive this number higher. California's close proximity to Oregon and Washington, two of the largest softwood-producing states, may help lower delivery costs.


The foundation for a custom California home will cost anywhere from $1,300 to $14,280. This brings the typical cost to around $7,800. The final cost of the foundation will depend on slope grade, as California isn’t known for flat land. Houses in California are typically built on a slab foundation, and the cost to build a basement is higher than most places.


Expect to pay around $175 per hour to rough-in electrical at a new California house. Most rough-ins are complete within 3 to 7 business days, but may take longer depending on the size of the home, the number of stories, and add-ons such as pools and speaker systems.


You can expect to pay around $5,000 per 1,000 square feet of home completed. But this will depend on the number of bathrooms, appliances, and any other water or sewage-running pipes you need.


The average cost of a roof in California will be around $22,400, but you might pay anywhere from $8,650 to $65,000. This comes down to the home's roofing material and how complicated it is to install the roof.

For instance, the average cost to install an asphalt shingle roof is around $16,050, while the cost to install a metal roof is about $23,000. Then, you have higher-cost roofs like tile ones, which cost around $28,130.


The average cost to build a driveway in California is around $6,750. While a driveway serves as the area you drive your car into, you can still customize it to your liking. This will depend on the length, width, and curvature.


The average cost of an AC unit is around $7,400. AC systems are typically a must in California because of the extreme heat found in a good portion of the state.

Furnaces will run around $5,000 on average. In milder California climates—including cities such as San Francisco, Sacramento, Humboldt, and Redding—you might need the furnace portion of an HVAC unit.


Expect to pay around $6,750 on average for a standard California landscaping installation project. You’ll want your new home to catch some eyes after it’s all built, so landscaping shouldn’t be left out of the final cost.

Cape Cod

The average cost to build a Cape Cod home in California is around $350 to $500 per square foot. Cape Cods are relatively common in California because they are great for adding height without seeming bulky. It’s a great way to increase square footage without necessarily needing more land.


Expect to pay around $180 to $400 per square foot, depending on customizations. Contemporary-style homes also have found a place in California thanks to their more modernistic approach, combining a little bit of farmhouse and mid-century designs to create elegant styles.


These home styles run around $350 to $500 per square foot in California, although it’s common to see numbers above that range. Mediterranean-style homes complement the California coastline and offer a grandeur look.

Cost Factors to Build a House in California

There are several factors you’ll need to consider beyond your typical construction costs. You need land for the property, and California has some of the most expensive land value around. The state also has recent mandates stating newly constructed homes must have solar panels.


Land costs in California are some of the highest in the nation, with it being the third-largest state in the country. For example, a plot can range from $50,000 to as high as $1 million in some regions of San Diego. Expect to pay around $150,000 on average for the land alone in California.

Solar Panels

California now has a mandate that requires new houses to come equipped with solar panels that produce electricity. The homeowner is responsible for this and should expect to pay around $8,500 extra. The inclusion of solar electricity will typically help lower your energy bill, helping offset the cost in the long run.


Expect to pay around $8,000 in total for permits. Building your dream home in California means you'll need to consider all the necessary permits to complete the project, particularly if you want a pool or a porch.

Interior Finishings

Of course, you'll need to complete the inside to your liking once you're done with the exterior. This includes appliances, fixtures, cabinets, and even doors.

Common interior finishings include:

Exterior Finishings

You’ll need to add windows and exterior paint as well to your finished product. If you want a patio and pool, consider these costs as well.

DIY vs. Hiring a Home Builder

Building a home is a multi-team process that even with the best pros can take anywhere from 6 months to 20 months, depending on material availability. Trying to build one yourself would likely take years—if not more. This is a job best left to a custom home builder near you.

However, there are ways you can save money in exchange for time. One way is to be your own construction manager, so long as you know what you're doing. Doing so could end up saving you around 5% to 15% from the final project, but it means you'll be hiring subcontractors and handling the ins and outs of the project.

Duties of a construction manager include:

  • Hiring subcontractors

  • Buying materials

  • Securing permits

  • Overseeing all work completed

  • Carrying worker’s compensation and liability insurance

  • Ensuring proper installation of all finishings to avoid voiding manufacturer warranties

  • Cleaning and disposing of trash and debris

  • Managing workplace safety

These are just some of the roles a construction manager might cover. You’d also need to obtain a general contractor's license before being able to handle any of these duties.


How much does an architect cost?

You’ll likely need to hire an architect near you to draw up plans to get the project started. This initial cost will be around $9,500 on average.

From there, the architect will typically charge between 8% to 15% of the final project if they need to do more work. But they’ll work as your construction manager from there on out, meaning you typically don’t need to hire one on top of your architect.

Should you build or buy a home in California?

Generally speaking, you're going to save money by buying an existing home. You'll roughly save around $150,000 by purchasing an existing home. This may mean not getting exactly what you want, but you'll be able to move in quicker and not stress over the construction.

What solar energy system is required for new homes in California?

The California solar mandate requires the solar power system to provide enough electricity to power the building annually. With this being a new home, you'll need to go based on approximation since you don’t know how much electricity you'll be using. According to the U.S. Energy Information Administration (EIA), if you go based on the annual average household electricity consumption—or 10,715 kilowatt-hours (kWh)—you'll need at least a large enough system to support that amount.

Should you build a custom home or a home in a housing development in California?

It typically costs around $125,000 in savings to build a home in a housing development, because the development company has purchased the land, saving you a significant amount of money upfront.
