Digging out a basement is a significant investment that varies widely based on numerous factors. Homeowners typically spend between $60,000 and $150,000, including excavation and finishing. Below is a deeper dive into the various factors and costs involved.
The size of the basement is a primary factor in determining the cost. Larger basements or complex layouts tend to be more expensive. Excavation costs can range from $75 to $150 per cubic yard of dirt, and overall costs for new basement space can range between $30 and $75 per square foot.
If the project requires raising or bracing the house, expect additional costs. Raising the house with hydraulic jacks costs between $3,100 and $9,400, while bracing or underpinning can cost up to $20,000.
Ensuring proper drainage and plumbing systems add to the overall expenses. New drainage systems can cost between $3,000 and $9,000, and plumbing installations may add between $1,000 and $3,000.

Necessary permits typically range from $1,200 to $2,000. Professional engineering services, crucial for structural assessments, can also run into the thousands.
Building a new concrete foundation can cost between $10,000 and $30,000. Additionally, unexpected repairs such as foundation issues during excavation can cost between $2,100 and $7,800.
To make the basement livable, finishing costs range between $7 and $23 per square foot. This includes materials and installations like flooring, plumbing, and electrical work.
