The average cost of building a house foundation is $5,000 - $8,000​.

How much does it cost to build a house foundation?

A structurally sound home starts with a strong foundation holding its weight and consequently, it can be considered the most important part of the house. 

For this example, we'll consider the cost of a new 1000 square foot foundation. The average installed cost is $5-$8 per square foot, or $5000-$8000.

Cost breakdown

  • Materials:
    • Poured slab concrete typically costs $3-$5 per square foot.
    • Footings 1 can add an additional $1-$2 per square foot.
    • A crawl space foundation can be a better option, but it also requires more materials and labor time and can double the overall cost of the project.
  • Labor: labor costs from contractors or concrete specialists typically adds another $2-$3 per square foot, for a total of $2000-$3000 for this project. On average, it takes three to four days from start to finish to dig out and pour the concrete.

Enhancement and improvement costs

  • Pouring the foundation is a good time to add radiant flooring 2. Radiant flooring heating 1 costs in a typical house $6,000-$14,000, but you may be able to get a discount if you do it with the foundation.
  • This is also a good time to install a foundation drain 3, which tends to add an additional $3000 to your total but can help prevent future, expensive issues.
  • Adding a sealant to the concrete can add another $0.50 per square foot but can help prevent expensive water damage issues later on.
  • Adding footings 1 for more complicated architectural details, such as stairs, can add $150 per footing 1 to your cost.

Additional considerations and costs

  • Foundation that is poured as an attached addition to an existing home might take longer and be slightly more expensive because of the need to work around existing buildings.
  • In most areas, permits are required for pouring new foundation. Talk to your contractor for details about regulations in your local area.
  • If the area needs to be leveled 4 significantly before the foundation can be poured, plan to add another $1000-$2000 and a few days to your total costs.
