- Step distance between rungs is to be 18 inches maximum vertical spacing
- Rungs: 12 inches wide or greater and must project a minimum of 3 inches away from wall, and a maximum of 6 inches. (Our Rockwell Well has built in steps, therefore it does not need a ladder.)

Windows Under Decks:
- The International Residential Code 2015 stipulates the following for basement egress windows under decks:
- Emergency escape windows are allowed to be installed under decks and porches provided the location of the deck allows the emergency escape window to be fully opened and provides a path not less than 36 inches in height to a public space (outside).
"We had a 5' egress window installed into our finished basement that allows more light and emergency access. Despite the monsoon rains we experienced this spring (which pushed back a lot of construction), all went well and the job was completed within the expected time. Mike's team was professional and they truly did a "no mess egress" installation. It looks great and we would use them again should the need arise."

"They communicated well during the job, completed the work on time and left the house clean. Good company to deal with."
