During this time of increased working from home and remote learning, additional space in your home is at a premium. An egress window converts your basement space into more livable space for an additional bedroom, a home office or a family room. Not only does it create more comfortable space to live, it can also significantly contribute to the resale value of your home.

Are Egress Windows Worth It?

Worried that your basement bedroom does not legally qualify as a bedroom?  There is a fix for that, but is it really worth it? We attempt to answer that question by analyzing the value egress windows add to your home resale value across different markets.

An egress window can add substantial value to your home and allows you to legally market a basement space as a bedroom. How much value does an escape window add? It depends on your house and your location. Egress windows are, however, one of the few projects in which you can fully recover your cost, and then some, in resale value. 

Even if you’re spending up to $6000 dollars for professional installation, you can market your new space as an additional bedroom (assuming you meet qualifications such as a closet and minimum 10’ by 10’ area) when it comes time to sell your house. 

Calculating the Value of Egress Windows?

Research the current average value for livable space in your community to calculate the potential added value for the new living space in your home. It’s a given that an additional bedroom contributes to the marketability of your home. Our formula multiplies the square footage of the additional livable space with the average home price per square foot in your market, and then divide that total in half to recognize that finished basement bedrooms usually appraise for between 50-70% of the above-ground value. This given value is determined by a range of factors such as the quality of the finishes, if there is a walk-out or not, and how the space stacks up to other homes in the area.

The formula is expressed as: 

(Average Home Price per square foot) X (New Basement Square Footage) X (O.5)

Using this formula, we analyzed the value egress windows add to home resale values across different markets. 

City Average Home Sales Price / Sq. Ft. Average Value Added from 12x12 Basement Bedroom
Seattle, WA $488 $35,136
Denver, CO $311 $22,392
Chicago, IL $223 $16,056
Pittsburgh, PA $144 $10,368
Atlanta, GA $214 $14,408
San Jose, CA $685 $49,320
Des Moines, IA $146 $10,512
Madison, WI $170 $12,240
Minneapolis, MN $185 $13,320
Boise, ID $225 $16,200
Birmingham, MI $280 $20,160
