All You Need to Know About How to Add a Basement to Your Home

The idea of adding a basement to your home might be a little hard to wrap your head around; maybe even seem a little impossible. However, not only is it done, but it can add massive value to your home while easily working around tight lot lines keeping you from expanding your living space. Although it might seem like a huge undertaking, the right team can easily get the job done while you focus on handling your daily obligations. To learn all you need to know about this project, just take a peek at this guide. 

Why Add a Basement to Your Home

When you add a basement, you effectively double the square footage of your home in one fell swoop. Not only does this give you a lot more living space, but also helps increase the value of your dwelling. Plus, the addition doesn’t even take up any additional lot space, leaving your front, back, and side yards intact.

Most Common Ways to Add a Basement

When you want to add a basement, you’ll need to decide between a home lift and basement excavation. Here’s how they differ.


A home lift raises the dwelling up off its foundation using sturdy lifting beams. As the home is suspended well above the ground, the renovation crew adds a new foundation and excavates the land as needed to create the basement. Then, they lower the home back down onto the new foundation and secure it in place permanently.


The basement excavation process starts with the creation of an access hole for the digging equipment and workers. After placing several supports, the team starts digging down into the dirt to the desired depth. Then, they put in permanent supports, reinforce the foundation, and complete the finished work to complete the basement build. 

For help deciding between these options, simply work with a skilled and experienced architect. With a review of your dwelling, they’ll check the total amount of space, lot egress, and other factors to make the right recommendations.

Total Cost of Adding a Basement

If you add a basement with a home lift, expect to pay anywhere from $40,000 to $150,000, depending on the house size, location, and other factors. Excavating a basement costs between $10 and $20 per square foot to complete the dig, pour the concrete, and close up the exterior access hole.

If you’d like the basement completely finished after it’s built, you’ll likely pay another $10,000 to $30,000. The total cost of the finished work depends on your preferred material type and quality plus the square footage of the space.

Top Considerations for Basement Builds

When building a basement in your home, your architects, contractors, and other experts will have to look at the land, building codes, and more to get the right results. Otherwise, the project could fail to meet your expectations in the long run.

The top considerations for basement builds include:

  • Presence of radon in the soil
  • Ability to meet building codes without violating lot restrictions
  • History of flooding in the crawlspace or around the home’s foundation
  • The need to move electrical wires, plumbing pipes, and other utilities
  • Placement of windows that let in enough natural light

Beyond all that, your architect must keep moisture mitigation, ventilation, and lighting in mind while designing and building your basement. Along the way, your architect will check in to gauge your preferences and adjust their approach to match your vision.

Who to Hire to Help Build a Basement in Your Home

Whether you decide to go with a home lift or basement excavation, adding a whole new living space to your home requires a skilled crew. On that crew, you’ll need architects to draw up the plans, create your interior design, and provide their project management services.

You’ll also need a full construction crew, including:
