Window Well and Egress Windows Installation
What Are Egress Windows?
Egress windows are specifically designed to meet minimum size and dimension requirements to allow occupants to escape or first responders to enter during emergencies. These windows must open easily without the need for special tools or force.
Legal Requirements
In most areas, building codes stipulate that:
- The egress window opening must have a minimum height and width of 15 inches each.
- The total clear opening must be at least 5.7 square feet for above-grade windows and 5 square feet for basement windows.
- The bottom of the egress window cannot be higher than 44 inches from the floor.
- A window well must be installed if the egress window is below ground, with a minimum area of 9 square feet and steps or ladders for easy escape.
Why Are Egress Windows Important?
- Legal Compliance: If you’re renting out basement units, egress windows ensure your property meets rental unit regulations. Without them, your apartment may not qualify as a legal dwelling.
- Safety: Egress windows provide a critical escape route during fires or other emergencies.
- Natural Light: Larger egress windows improve basement lighting, making spaces feel more open and inviting.
Window Wells for Egress Windows
For egress windows below ground level, a well-designed window well is essential. It ensures that the space around the window stays clear of water and debris while providing the necessary clearance to meet safety requirements. The addition of a drainage system within the window well also helps prevent flooding in the basement.
