Understanding Egress Window Requirements
An egress window is designed to serve as an emergency exit. It is a key feature in any finished basement used as a bedroom or living space. Egress windows must meet certain requirements, as these windows must be large enough to allow someone to escape in the event of a fire or other emergency, and they also allow emergency personnel to enter the home.
When is Egress Window Installation Required?
In St. Louis, and under the International Residential Code (IRC), an egress window is legally required in any basement that contains a bedroom. If you are finishing your basement or converting the space into a legal bedroom or rental unit, an egress window must be included.
Local building codes often adopt or adapt these national standards. In St. Louis and surrounding areas, municipal building departments may enforce slightly different versions of the IRC, so it is crucial to work with a professional who is familiar with these local regulations.
Egress Window Requirements and Specifications
To meet code requirements, an egress window must:
- Have a minimum opening width of 20 inches
- Have a minimum opening height of 24 inches
- Offer a minimum net clear opening of 5.7 square feet (5.0 square feet for ground-floor windows)
- Have a sill height no more than 44 inches above the floor
- Be easily operable from the inside without the use of keys or tools
If the window opens into a window well, additional requirements apply, including a minimum clearance area of 9 square feet and a ladder or steps if the well is deeper than 44 inches.
Benefits of Installing an Egress Window
Even when not legally required, installing an egress window can add value and safety to your home. Some of the main benefits include:
- Improved Safety: Provides a quick exit during emergencies
- Increased Natural Light: Brings light into otherwise dark basement spaces
- Better Ventilation: Improves airflow and reduces musty odors
- Higher Home Value: Makes your home more marketable and code-compliant
