The bottom of the egress window opening cannot exceed 44 inches from the finished floor
The clear opening of at least 5.7 square feet
The opening width of at least 20 inches
Opening height of at least 24 inches

Proper installation and waterproofing of the egress window well serves to keep the basement dry. The well needs to be secured in multiple places to prevent movement. Specific materials seal the window well externally and internally, preventing seepage and water leaks.
