My FIL is coming home in a wheelchair in 4 days. My husb. wants to build a ramp for him. But do you think it's reasonable to get a portable one for now? Can we get one in a few days? I read that to build one it is to be 1 ft long for each inch of height (like, if porch is 24" high then ramp should be 24 ft). Can you tell me anything else? Does he need a permit to build? I wonder if it has to be real good, lasting & 'beautiful', he might use a walker in awhile. He can use a walker a little bit but someone must be with him in case he falls backwards. As a matter of fact, he lives alone. My husb. is going to stay with him for the 1st week.
