I live in one floor Apt in NC and I have Mutible Sclerosis. What I need to know how I could build a wheel chair ramp so that I may enter and leave my apt in my wheel chair. I beleive the regulation call for 2" for every 4'. The step in front of my apt is 5". So to comply to the regs the ramp needs to be 5' long. I need a design so that I can build one that would satisfy the property owner and city codes. It needs to be made out of wood so that I may save the property owner step and I can take it with me if I move.
