  • You’ll need to pay a structural engineer and an architect for plans.

  • Don’t forget to consider the cost of the land where you plan to build.

The average cost to build a custom home is $825,000. You could pay as little as $160,000 for a small, 800-foot custom build with mid-range finishes or as much as $3,500,000 for a 4,000-square-foot home with luxury finishes. Pricing varies widely by location and also depends on home size, material quality, foundation type, and more.

Cost to Build a Custom Home By Number of Bedrooms

Many homeowners will begin their house plans with the number of bedrooms they want or need, so it’s helpful to use this as a gauge to determine the cost to build your custom home. Total costs won’t depend directly on the number of bedrooms, but it’s a good benchmark to use to get a rough idea of your total. Adding bedrooms means more square footage, both for the bedrooms themselves and for added living area to support a larger family.

Number of BedroomsAverage Build Cost
3$600,000
4$825,000
5$1,000,000
6$1,200,000

It costs between $200 and $550 per square foot to build a custom home, so if you know the square footage you want, you can use this cost range to come up with a more accurate price estimate. You can use a cost closer to the $200 mark if you plan on using low-end or mid-range finishes and move closer to $550 per square foot if you know you want a luxury home with high-end materials and features.

Square FootageCost Range
800$160,000–$440,000
1,000$200,000–$550,000
1,500$300,000–$825,000
2,000$400,000–$1,100,000
2,500$500,000–$1,375,000

4,000$800,000–$2,200,000+

Custom Home Builder Costs

Building a custom home is a highly complex project, so hiring a custom homebuilder near you is all but a requirement. Labor accounts for between 40% and 50% of the total, or an average of between $330,000 and $415,000. Labor costs are higher for custom home builds because your contractor will be doing everything custom, which requires more planning and may extend your new construction timeline.

Architect Cost

Building custom means there are no pre-approved building plans to get permits or detailed and specification reports for your builder to work from. These types of construction documents are necessary to move forward and help ensure you know exactly what your finished home will look like. Hiring an architect costs between $10,000 and $60,000, depending on the size and complexity of your home.

Structural Engineer Cost

You’ll also need to ensure your new home is structurally sound, so you’ll need to hire a structural engineer. A structural engineer costs between $2,000 and $10,000. For this amount, you’ll get their stamp of approval for the structure, as well as structural drawings that your architect will use to design your home.

Additional Pros to Consider Hiring

Your best option is hiring a custom homebuilder to tackle everything from pouring the foundation to putting on the roof and installing flooring. If you choose to hire individual building contractors, though, you can use the pricing below to get estimates for the total labor cost.

Cost by Location

The cost to build a custom home varies widely based on the location. Prices scale with labor costs, so totals will be higher where the cost of living is above average, like in coastal states or near major metropolitan areas. You may also see a higher cost in remote areas where getting to the construction site is challenging or connecting to utilities is more time-consuming and expensive.

StateAverage Cost
California$1,200,000
Florida$845,000
Georgia$755,000
Illinois$790,000
Michigan$760,000
New York$1,000,000
North Carolina$805,000
Ohio$785,000
Pennsylvania$785,000
Texas$765,000

Additional Cost Factors

There are many other cost factors that can affect your custom house build cost, from the cost of the land and excavation to the type of foundation and home systems you choose.

Land and Land Preparation

The average cost to build a custom home of $825,000 doesn’t include land, which, of course, you’ll need before you can start planning your project. Land can cost anywhere from a few thousand dollars to millions, depending on the size and location.

A crucial mistake to avoid when building a home is neglecting to consider the land preparation you need to do. Below are just some of the costs you may need to cover. Speak with your custom home builder to help decide which line items you need to think about.

Land PrepCost
Grading$5,000–$20,000
Impact report$1,000–$3,000
Land clearing$1,300–$6,000
Land survey$375–$750
Perc test$750–$1,900
Soil testing$650–$2,200

Utility Connections

Connecting utilities to new construction costs an average of $20,400, but this is only a concern if you’re building on a plot that didn’t previously have a home on it. The total can increase to $60,000 or more if you’re building on a remote plot that requires long electrical, water, and sewage connections.

Even if you demolished an old structure where you plan to build your new custom home, you might want to factor in the cost to connect to the sewer if the old property was on a septic system. Running a lateral sewer line to your plot costs between $1,500 and $6,000. If you plan to stay on septic, building a larger home may require a bigger system, so factor in the cost of replacing your septic system, which averages $12,000.

Permits

You’ll need building permits for all new construction, and permits come with fees that can fall anywhere between $1,000 and $4,000. Your total depends on the size of the new home and your local municipality’s fee structure. Luckily, a single new construction permit can cover all of the smaller permits you’d normally need for individual parts of the project, like plumbing, roofing, and electrical.

Foundation

Pouring a new foundation will cost between $5 and $37 per square foot, depending on the type of foundation you choose. A slab foundation is the simplest and most affordable option, while a basement foundation requires more excavation and materials to construct.

Foundation TypeCost per Sq. Ft.
Basement$20–$37
Crawl space$6–$18
Pier and beam$6–$12
Slab$5–$18

Framing

Framing for your new construction will cost between $7 and $16 per square foot, depending on the complexity of the job. For a 2,000-square-foot house, this portion of the build will account for between $14,000 and $32,000. You may need to pay for masonry work instead if you’re considering the cost of a concrete house or a brick house.

Home Systems

When you include plumbing and electrical, and installing ductwork in an average-sized custom home will cost between $25,000 and $50,000. You’ll also need to account for installing the HVAC system in addition to the ductwork, which can add between $5,000 and $12,000.

Finishes

The finishes for your custom home include siding, exterior trim, gutters, soffits, and fascia boards on the exterior. Inside, finishes include flooring, drywall, painting, tile work, installing the kitchen cabinets, installing the bathroom vanity, installing appliances, and more. This portion of the job can cost between $75,000 and $300,000 or more, depending on the quality of the materials you choose.

Landscaping

After your new custom home is built, your property will likely be a mess from the construction. At the very least, you’ll want to grade the property and seed it, which can cost between $400 and $1,800. However, most homeowners will want a custom yard to match their new custom home, so you may want to consider the following costs, too.

ProjectCost Range
Asphalt driveway$3,000–$7,500
Concrete driveway$2,700–$14,500
Concrete patio$2,000–$5,000
Concrete walkway$1,600–$2,400
Deck$4,300–$12,500
Firepit$200–$3,000
Gazebo$2,500–$9,500
Outdoor kitchen$6,000–$100,000
Paver patio$2,400–$7,000
Pergola$2,100–$6,300
Porch$4,000–$90,000
Water feature$1,000–$5,000

Home Remodel vs. Building a New Custom Home

Remodeling a home costs an average of $65,000 and tops out around $250,000, so even at the high end of the range, going that route is far more affordable than demolishing your existing structure and building a new custom home.

However, building a new home gives you more freedom when it comes to the size and layout of your house. Remodeling your home could mean making minor changes to the layout and even building home add-ons to increase the square footage, but you’ll still be somewhat restricted by the size of your old foundation and the structural components that are in place. If you want total freedom to create your dream house, building a new custom home is the best option.

How to Save Money When Building a Custom Home

Building a custom home can get expensive very quickly, with prices sometimes reaching up to $3,500,000. There are a few things you can do to help keep costs to a minimum.

  • Choose more affordable materials: Materials account for between 50% and 60% of your custom home build costs, so choosing more affordable options can save you tens of thousands of dollars.

  • Work with an existing design: Consider using an existing design your architect has and making modifications instead of starting from scratch. This alone could save a few thousand dollars on the architect and structural engineer fees.

  • Focus on energy efficiency: The federal government and many local and state governments offer rebates, tax credits, and other incentives for energy-efficient buildings that can help you save. Better efficiency also means lower utility costs in the long run.

  • Build close to utilities: Running utilities to a previously undeveloped plot can add tens of thousands to your total. Instead, build on land where there was previously a home so that you know you have nearby utility connections.

  • DIY what you can: Planning and constructing your new custom home is a job for professionals, but you can save some labor fees if you can DIY things like laying flooring, installing drywall, and painting.

  • Work with a local custom homebuilder: Hiring a professional to build your custom home is crucial, and choosing one who has done similar work in your area will help the process go smoothly. A local pro will know what to expect in terms of building code, regulations, soil conditions, and more. Ultimately, this could end up saving you both time and money.

Frequently Asked Questions

It’s almost always more affordable to buy an existing home than it is to build a new one. Existing homes have depreciated to some extent by the time you buy them, and taxes on existing homes tend to be much lower than taxes on new construction. However, you have complete say over the layout and look of a home if you build custom, while an existing home is harder to match to the vision you have of your dream house.

Yes, you can finance new construction, although you’ll need a different type of loan than you’d use to buy an existing property. You can take out a construction loan, which provides funding for a project for the duration of the construction. A construction-to-permanent loan is more common, as the loan converts to a traditional mortgage once you move in. You can also use a bridge loan, which funds the construction before you’re able to sell your old home.
