If it is less than a flight of stairs, ( have 3 steps between the ground floor family room and the rest of the house) you can use an indoor/outdoor lift. This also will work outside if you don't have the room to have a switch back ramp. FYI to ramp to a 30" porch would take about a 30 foot ramp. We have a Mac PL50 for 50" lift, they also make a 72" model. I lost a closet to have it installed btween the family room and office it is about 4 ft square with a platform and tower on one side. Before we installed this he took his chair to the garage, out to the ramped deck, in the glass slider that had a small ramp just to go to bed. Soooo couldn't go to bed when it was raining, had the new lift before the snow flew. They cost between 3 and 5 thousand, it allowed us to stay in our house with out making major changes. Penny
