When you’re buying a house, your real estate agent might mention different types of basements, and it can feel like a whole new vocabulary. We’re here to break it down in a simple way so you know exactly what they mean and what to look for as you tour homes.
We want to give you pros and cons for each type so you can decide what type of basement you prefer, so you are informed going into a house hunt. For all basements, keep your eyes open. Look for water stains on concrete or walls, a damp smell, or visible mold and mildew.
Walkout Basement
A walkout basement is constructed on a sloped lot. There is more natural light, higher resale value, and and easy ventilation in the basement. This is a real plus when the lot has a scenic view, and outdoor access is an attraction.
There are a few cons to this type of construction though.
- There is a higher potential for water intrusion, so double check the grading–it should already be away from the home because of the sloped lot, but ground settles and this may have changed since the home was built. Also inquire about the homes exterior drainage system.
- Since there is another entrance door, it will require maintenance, just like any other exterior door.
- Security must be taken into account, as it is an additional access point to the home.
Walk-up Basement
Walk-up basements are much like a walkout basement, but are built on a flat lot. The basement is below grade except that the stairs are in a stairwell. The only additional minus to this is keeping the stairs and landing clear of debris, ice and snow.
None
This is exactly how it sounds, if the real estate agent says “none” when talking about a basement, then there is no basement–the house is built on a slab. Advantages are there are no basement steps to contend with and no chance of a flooded basement. Disadvantages are that the utilities are on the main floor and there may be increased background noise from an HVAC unit and washers and dryers, and there is no below ground storm shelter.
Partial Basement
A partial basement is just what it sounds like–a basement only under a portion of the home. Often these are not meant to be much more than utility spaces. No extra living space, but it will isolate furnace and washer/dryer noise from the rest of the house, and provide a storm shelter.
Full Basement
Full basements are functional to use for great living spaces and adds lots of square footage to the home. Many homeowners frame out and soundproof the utility areas, and use the rest for extra bedrooms, a guest suite, home office, or a home fitness area.
The full basement only has one major detracting point. If you want to use any of the basement as a bedroom, you must have an IRC code compliant window well. Please check your state’s code here. Please use this as a reference, and refer to your local building inspector as the final authority.
Crawlspace
A crawlspace is a just that–a space under the main floor to access plumbing, HVAC ducts, and electricity. Depending on ceiling height, this is not generally a usable space. Inspection of this area is very important before purchase to be sure there are no water problems.
