Installing spiral staircase
I bought an old metal spiral staircase from the 70's to attach to my deck outside to get to the yard. I'm trying to stay within code for resale (this is a new house. I added extra ballisters, but a friend mentioned the steps are only 2 feet wide and he thought this was not within code nowadays. Is this true? If so, what is code width? I live in NC. Also The top will be bolted to the deck and the bottom of the pole is a 5" x 10" plate with 4 bolt holes. After I pour a footing and small landing pad, how do I attach this and is this plate large enough for today's codes?
