ADA Ramp to piered home

[mikedre]

I created a home on short piers and want to add a ramp, but the ramp floats above the terrain. How to I make it come down to the terrain?

Turn off automatic heights in the ramp dialog and then you can set the height to whatever you want.

I tried that, but it doesn't help. Let me give you a brief synopsis. Creating the piers didn't work the suggested way, so I set the subfloor to 36" above the terrain. Does this or should this cripple the placement of the ramp?

It just looks like your ramp is too short.  It's hard to tell from the picture, but it looks like the top of your ramp is level with the porch.  If it's not level, then you need to raise or lower the top height so it is.

 

For an ADA ramp, your ramp will need to have a 1:12 slope.  If your subfloor is 36" above the terrain, then your ramp will need to be at least 36' long.  This is assuming that your terrain is flat.  If your ramp needs to meet the terrain at a lower point, then it will need to be even longer than 36'.  You could also make it steeper but then it probably wouldn't meet code.
