Egress Window FAQ for Columbus, Ohio Homeowners
Straight answers about code sizes, bedrooms, wells, permits, and getting a free estimate.
What is an egress window?
An operable emergency escape and rescue opening sized so a person can get out and a firefighter can get in. In Ohio, one-, two-, and three-family dwellings generally follow the Residential Code of Ohio (RCO), which is based on the International Residential Code - including Section R310 for emergency escape openings.
Do basement bedrooms need an egress window?
Typically yes. Codes require an emergency escape opening in sleeping rooms and in many habitable basements. Confirm the exact rule with your local building department.
What sizes does the code use?
Under IRC/RCO Section R310 baselines commonly cited: at least 5.7 square feet of net clear opening (5.0 square feet exception for grade-floor openings), minimum 24 inches clear height, 20 inches clear width, and a sill no more than 44 inches above the floor. Window wells generally need at least 9 square feet of floor area with 36-inch projection and width; wells deeper than 44 inches need a permanent ladder or steps. Always verify the edition and amendments your city enforces - see our code guide.
Will you help with permits?
Yes - help with permits and code questions is part of the process. Exact permit steps depend on your city or township building department.
How much does an egress window cost in Columbus?
Installed prices vary with foundation type, well depth, window style, drainage, interior finish, and permits. Request a fast, free estimate for your address, and read our cost factors page.
Can I put a cover over the window well?
Often yes, if the cover or grate can be opened from inside without a key, tool, or special knowledge, and it does not shrink the required clear opening. Follow the code edition your city enforces.
What is the difference between a Bilco door and an egress window?
A Bilco-style bulkhead is an exterior stair hatch. An egress window is a code-sized window (often with a well) that adds light and ventilation while providing an emergency exit. Which option fits depends on your lot, foundation, and goals.
How long does installation take?
Many residential egress projects are planned as a short on-site job, often about one to two days depending on foundation type, well depth, and weather. Your free estimate will outline expectations for your home - we do not guarantee a fixed turnaround.
