Basement Remodel questions, answered by experts

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs.
