Third Floor Egress Requirements
Illumination levels shall be permitted to decline to 0 6 footcandle 6 lux average and a minimum at any.
Third floor egress requirements. Egress window well code requirements. Basements habitable attics and sleeping rooms need to have an egress opening. I m not going to explain all of these requirements but i ll list the basics. The minimum egress window opening is 20 wide.
I have a 4 unit there are some bedrooms on the third floor that don t quite meet egress requirements because it s a 22 drop from the window sill instead of the maximum 20 i ve been thinking of solutions and came up with something that i think might just work. Emergency lighting facilities shall be arranged to provide initial illumination that is not less than an average of 1 footcandle 11 lux and a minimum at any point of 0 1 footcandle 1 lux measured along the path of egress at floor level. Two floors and you can have a stair and a jump platform but three floors you will need two stairs. The bottom of the required opening must be within 44 of the floor.
I recently saw a home built. The minimum egress window opening height is 24 high. The area of a window well shall not be less than 9 square feet with a horizontal length width of no less than 36 inches. The bottom of the egress window opening can t exceed 44 from the finished floor.
It is my understanding that egress from a third floor in a single family home per the irc requires two separate stairs. If you re in minnesota check out section r310 of the minnesota state building code for all of the requirements. When the sill height of an egress window is located below grade common for egress windows provided for a basement a window well must be provided.
