The Cost to Build a House in California (2024)

Framing ($1,406 – $7,661)

Framing is when the sticks go up, and a structure starts to take shape. Expect to pay between $1,406 and $7,661 for this house construction phase. Framing costs tend to vary due to both the size of the home and the complexity of its design — a one-story home with 2,000 square feet of living space will generally be less expensive to frame than a two-story home with the same square footage.

The earthquake standards can also increase the cost of framing the home, Laniado notes. If you’re building an open-concept plan with a wide open space, you may need to add a metal frame to help support the home in a quake, and “that adds a considerable amount to the cost of the building.”

Roof ($5,854 – $13,118)

Roofing doesn’t come cheap — whether putting one on a new house or replacing the roof on an existing home. The costs of a new roof typically range from $5,854 to $13,118 in California.

Asphalt shingles are commonly used for residential roofing in California, Laniado said. Depending on the shingle style, purchasing and installing 100 square feet of asphalt shingle ranges from about $270 to $1,500.

Tile roofs are popular for high-end homes in California, Aballi said. Prices for buying and installing a clay tile roof can range from $28,000 and $50,000 for a 2,000 square foot home.

Siding ($5,572 – $17,603)

Siding is another big variable: Are we talking vinyl, wood, brick, concrete, stone, stucco, or something else entirely? Siding costs range between $5,572 and $17,603, with vinyl or engineered wood siding typically costing between $3 and $12 per square foot.

Wood siding and cement board siding are a popular choice, Laniado says.

Fiber cement siding costs between $5 and $13.50 per square foot for the material alone.

Stucco is another house siding option commonly found in California, with material prices generally in the $5 to $6 range per square foot.

Appliances ($10,875)

Appliance pricing also varies widely. Depending on the brand, functionality, finish, and so on, you’ll spend an average of $10,875 if the home does not come with any, but you expect to spend as much as $24,400 on higher-end appliances.

HVAC system ($10,000)

The installation of a new heating and cooling system could cost upwards of $10,000, depending on the size of your home.

Plumbing system ($2,280 – $5,120)

Plumbing can cost anywhere from $2,280 to $5,120 on average — not including fixtures like sinks and toilets.

Electrical system ($2,400 – $4,000)

The cost to wire a full house is, on average, between $2,400 and $4,000.

Building permits (variable)

Permits vary by state, city, and county but can typically range from a few hundred dollars to a few thousand. Both Aballi and Laniado agree that the permit process in California can be challenging and time-consuming.

In addition to a building permit, the project will need permits for grading, electrical, mechanical, and plumbing. When applying for the permit, the contractor must also provide various documents, including a site plan, drainage plan, floor plan, structural plans and calculations, landscape and irrigation plans, drawing of the exterior elevation, and a geotechnical report.

The permitting process for a new home can take up to six months, Laniado says. That means the homebuyer will have to pay rent or a mortgage on their current home for months before the new home can be started.

Finishes and fixtures (variable)

Finishes and fixtures comprise everything from countertops to sinks, and lighting to flooring. Pricing varies widely and depends heavily on your preferences.

Average carpet installation costs can start at several hundred dollars and go up to $3,000, while hardwood flooring installation starts at around $2,474 and up to $7,032.

Laminate countertops range from $842 to $1,735, while granite averages from $2,250 to $4,500.

The quality of the finishes is a major driver in the cost of a custom home, and there’s no upper limit on the cost of building a custom home, Laniado says.

“Here in L.A., there are people who really want the high-end stuff.”

Building a custom home vs. a home in a development

As a general rule, building a custom home that is tailored to your every need will be more expensive than buying a tract home from a builder. On average, building a custom home in California will cost $500 or more per square foot, according to Aballi — while building a tract home in California will cost $300 to $350 per square foot, according to Laniado.

Building a custom home will also require you to assemble a team of experts to design and build the home from start to finish. Here are the team members you will need and a breakdown of what they might cost you:

Architect (5% – 20% of the final build cost)

Hiring an architect will be integral to making your vision come to life when building your custom dream home.

Before you search for the right architect, know what you are looking for. Be sure to do your research and ask your network for recommendations for architects in your area who have experience designing the kind of home you are looking to build.

The cost of hiring an architect could make up anywhere between 5% and 20% of the final cost of the build.

For a 2,000-square-foot home in California, with a final build cost of $1 million, or $500 per square foot, that would amount to $50,000 to $200,000. Some architects will charge by the hour or per square foot of the build for their services, but this is less common.

General contractor (10% – 20% of the final build cost)

A general contractor will oversee the entire process of building your custom home — they will also be responsible for hiring and paying subcontractors, vendors, and construction workers. General contractors typically charge a “cost-plus” fee arrangement, which accounts for the cost of the labor and materials plus a negotiated fee for the general contractor. This usually comes out to 10% to 20% of the final cost of the build.

Additional costs to build a custom house in California

As we mentioned, building a custom home usually comes with additional costs. Again, your agent can help you determine more accurate costs — these are average figures provided to give you an idea.

Land survey ($376 – $768)

Land surveys, which identify your property lines and land features, range between $376 and $768.

Excavation and grading ($1,667 – $6,684)

If you’re buying a tract home, the land price will be rolled into the overall price to build a home. If you’re buying a lot on your own and then building a custom home, you can expect to pay between $1,667 and $6,684 to clear the land if you hire an excavation contractor. If you build in a rural location where city services like water, sewer, and electrical connections aren’t nearby, getting the services to your lot could cost up to six figures, Aballi says.

Common styles of homes in California and their average costs

Some of the most common home styles in California include Cape Cod, California Ranch, Victorian, Mediterranean, and Modern. Each has its unique features and costs. Here is a look at some of these styles and their average costs (all in):

More affordable options for building a home in California

While going with a bare-bones building strategy can get you into a new construction home for less, cheaper isn’t always better. Shoddy build quality will inevitably lead to problems down the road — anything from a leaky roof to poor sound insulation can be a frustrating discovery when you’ve only been in your new home for a few months — and there’s value in creating a home you genuinely want, not just one you’re settling for.

Alternative home-building options can give you more for your money and offer valuable flexibility during the construction process.

Tiny homes ($30,000 – $60,000)

A tiny house is usually 600 square feet or less in size. They’re not ideal for large families, but building a tiny house can be faster and more affordable than a conventional home if a smaller space fits your lifestyle.

Tiny homes cost between $30,000 and $60,000 to build, on average. They can also be a great option as a starter home — especially since starter home prices have doubled and tripled in SoCal and the Bay Area.

Another option that’s popular in California is the Accessory Dwelling Unit (ADU), which is also known as an in-law suite or granny flat. ADUs are built in the backyard of an existing home, and some local governments allow them to increase available housing. If your parents or children already own a house in an area where ADUs are allowed, you could consider building a small, separate living space on their property without buying land.

Studio Shed, which makes prefabricated buildings often built from scratch. The architect/design fees are baked into the price, and the company sources materials directly. Producing the buildings in a factory also reduces the amount of labor needed at the job site, says Jeremy Nova, the company’s co-founder.

Studio Shed prices range between $100 and $140 per square foot, depending on size and style. Buyers can customize their units, increasing the per-square-foot price, just as it does when you build a larger house.

Adding onto an existing house

Instead of building new, some California buyers choose to buy an existing house and do an extensive addition to increase the size and amenities of the home, Aballi says.

Getting permits for an addition, even a large one, is faster than getting a building permit for a new construction home, Laniado shares. However, the per-square-foot cost of the addition may be higher than building an all-new house. Challenges for adding to an existing house include:

• Tying in the new foundation with the existing one.
• Working in a tight, compact space.
• Less opportunity for economies of scale.

Is it cheaper to buy or build a home in California?

Generally, buying an older home will be cheaper than building a home. In California, prices vary widely. For example, buying a home in San Bernardino will cost around $345 per square foot, while an existing house in a smaller city, like Fresno, may cost between $252 per square foot.

While building a home will almost always come with a higher price tag upfront, there are some long-term savings that new construction homeowners enjoy:

• Energy efficiency: Newly built homes are generally more energy efficient than older homes — new construction homes are up to 30% more efficient than homes built 10 years ago. This is partially due to stricter energy regulations and better insulation and windows in new homes.
• New home warranties: New construction homes are often covered under builder warranties for a specified period. When purchasing an older home, most key systems, such as the HVAC, roof, and plumbing, will be older and no longer covered under any kind of warranty.
• Fewer maintenance costs in the first few years: With a newer home, you can count on your HVAC, plumbing, electrical system, and more to function properly with little required maintenance in your first few years of homeownership. Older homes will likely have older roofs and systems, requiring you to pay for replacement much sooner.
