Emergency Escape and Rescue Openings – Section 310
Section 310 of the International Residential Code pertains to all single and two family homes. The intent of this code is to keep you and your loved ones safe by requiring a secondary means of egress in basement level living spaces. This egress allows occupants to escape safety in the event of fire if the main stairway is impassible and provides firefighters direct access to the basement area. BILCO basement doors and egress window wells both meet the requirements outlined in the codes listed below for emergency egress in finished basement areas.
The IRC building code is updated every three years and adaptation varies with each state. Check with your local building department to determine what version of this code is being currently enforced in your area.
