Cost To Build A Basement Per Square Foot

If you want to build a basement, then you should know how much is it going to cost. This is because basements are very expensive, and if you do not know how much it will cost, then you could end up paying more than what you had expected. You need to calculate the amount of money that will be involved in building the basement per square foot. You can then use this information to decide whether you should build your basement or not.

It is important for you to make sure that the contractor whom you hire has experience when it comes to building basements. This way, they will be able to determine if there is any problem with your foundation before they start working on your project. It also helps them to come up with solutions that will address these problems before they become too big for them to handle on their own without causing any damage while doing so.

You should also consider getting bids from different contractors before deciding on which one offers the best deal based on their pricing structure as well as their quality of workmanship. Basements are a great addition to your home, and they’re definitely worth it. They provide extra space for storage, entertaining or a place to get away from it all. But what is the cost of building a basement? Is it cheaper to build one yourself or hire a contractor? And how by square foot does it cost? We’ll go over those questions here.

What is the cost to build a basement per square foot?

The cost to build a basement per square foot depends on the type of basement, the size of the basement, and the quality of materials used. The average price for building a full-size basement is around $3.00 to $10.00 per square foot. This includes labour and material costs but not architectural fees or site preparation.

It’s important to remember that there are many variables which can affect your final price tag—beginning with whether you want an above-ground or fully underground one. The most important factor will be how much work needs doing before you can start laying down those bricks (or pouring concrete).

Basement Construction

The cost of basement construction is the most expensive part of the project, but it also depends on your square footage. The more square feet you have to work with, the more it will cost you. You may want to consider building a small basement if your budget is tight. If you’re planning on building a family room or rec room in your basement, then make sure that there’s enough headroom for everyone (at least 8 feet). This can be achieved by using high-quality materials such as steel beams and drywall instead of wood framing which is cheaper but less durable over time.

Basement Finish

  • Carpet. Carpet is a great way to finish a basement. It’s easy to clean, it provides some soundproofing and can be installed in just about any room in the house.
  • Tile or stone flooring – If you have the budget for it, tile or stone flooring can really add value and beauty to your basement by creating an inviting space that makes your guests want to spend time there.
  • Concrete – Although concrete floors are very durable and inexpensive, they are not very comfortable when bare feet touch them so make sure you have socks on before trying out one of these floors.
  • Drywall – Dry walls are easy to install and provide excellent insulation for your home but do require periodic maintenance such as painting every few years if you don’t want them looking dingy over time.* Paint ceilings white or light colors like cream or light taupe shades which will make the ceiling appear higher than its actual height

Landscaping and Outdoor Space

If you want to maximize the value of your home, it is important to consider landscaping. Landscaping can make or break a sale and can also help sell your home quickly in a hot market. If you’re planning on selling soon, then it’s worth investing in updating the outdoor space of your basement.

However, don’t get too carried away with landscaping costs as they tend to be one of the most expensive aspects of building a basement. The cost will depend on how much work you do yourself and how much effort you put into keeping up with maintenance throughout years after completion.

Location and Cost of Materials

The location of your basement will have a major impact on the cost of materials. Materials are generally more expensive in urban areas, because there is more demand for them. For example, contractors in Ontario charge less per square foot to build a new home than contractors in British Columbia.

Contractors also mark up their costs during certain seasons because they know people have less money (e.g., winter) and tend to be less selective about who they hire for projects that require outside work (e.g., summer).

Structure Steel

Steel framing is used for the basement walls. Steel framing is stronger than wood and therefore costs less per square foot.

The cost of steel structure framing varies based on the size of your basement and how complicated it is. Another major factor in determining cost is whether you want to use an open or closed truss design; this will determine whether you need to hire a structural engineer to draw up plans for your home’s foundation.

In general, steel frame construction costs about $15-$20 per square foot for materials only (not including labor). You can expect that additional work like concrete reinforcement or foundation repairs may increase this amount by about $10-$15 per square foot


Concrete is a mixture of cement, sand and gravel. It can be poured in place or precast, either way it’s an excellent choice as a basement floor. Concrete is durable, strong, and has good insulating properties. It acts as an excellent sound barrier as well.

Framing (Interior & Exterior)

Framing is the basic structure of your basement, including framing in walls, floors and ceilings. This can be done by a contractor who specializes in framing or by you or someone else on your construction team.

Framing can be one of the most expensive parts of building your basement because it requires special tools and materials to create a sturdy structure that will support all of your new space’s weight. It may also require more time than other parts of construction because it needs to be done correctly from start to finish before moving on to other tasks like drywall installation or painting.

Tile and Stonework

Tile and stonework can be more expensive than other materials. It is also more difficult to install, which may result in a higher cost per square foot. The costs for tile and stone are dependent on the type of material you choose, but most tiles will range from $6-$8 per square foot. If you opt for a more expensive type of stone, then this price tag could double or triple.

The good news is that once you’ve purchased your tile and stone, installation will take only one day (if you don’t count prep time). After all, it’s just laying down some mortar between pieces of slate—nothing too complicated there.

Carpentry and Masonry

Carpentry and masonry are the most expensive parts of a basement. Carpentry and masonry can be done by the homeowner, but it is time consuming.

Carpenters and masons often have their own crews, which means they will be spending more money on labor than materials (although this depends on your area).


Plumbing is a complex system that can be difficult to understand. The cost of plumbing depends on the size of your basement, but it’s also important to consider how many fixtures you want in your new basement. You may want to build an addition onto your home so you can have more space for a bathroom or laundry room. If this is the case, consider hiring a professional plumber instead of doing it yourself.

The project cost will vary depending on the size, features, and design of your basement. It can also be affected by the amount of work required to prepare the site for construction. The cost to build a basement per square foot is generally higher than other rooms in your home because it requires more labor and materials than building a bedroom or bathroom would require.
