As I understand it the ADA requirement is 12:1 or 12" for every 1" of rise, so a 7" rise would be 14 feet. However, if it is your private home you can install a ramp at 12:2 and if it is aluminum, or what is considered a non-permanent structure, you do not need a permit but make sure to get the correct threshold end piece to make the transition to the ground smooth. They are relatively easy to install. Every 10 foot of ramp should have a platform which would lessen the angle of the ramp to a smoother transition. Look at the ADA website for information on whether you need a platform depending on the layout of your entrance and yard. The beauty of an aluminum non-permanent ramp is that if you need to move you can take it with you. If it is over a grass area remember to get yard fabric to prevent weeds from growing under the ramp and simply cover with mulch or like choice. I bordered ours with paving stones to retain the mulch in place which are on average $.50 a piece. For muddy areas you can use decomposed granite to cover the walk area and it is low maintenance with a weed kill product to prevent growth in the walk way to make for smoother surface and less mess.
