My elderly mother is moving in with us. She requires a handicap ramp to get into the house. Is there financial assistance for this?

Call your Office of Aging. Explain that Mom is blind and needs a ramp. In our County, there is a disabilities dept that installed a metal ramp for a friend free of charge. The stipulation being that it got returned when it was no longer needed.

My neighbor's ramp is done in a zigzag...one ramp starts sideways at the steps coming down to a landing, the second ramp from the landing going in opposite direction.

Boy Scouts for an Eagle project! Contact your local group and see what they say. Here scouts are always looking for a straight forward project.

I think what Mayday said is correct. The ramp would be too steep. I’ve seen homes where an actual platform was built over the steep steps and raised everything to top of the step level. That involved a lot more construction and materials than a simple ramp.
I hope I am explaining this correctly.
As far as an agency to provide the money to cover the materials I am not sure one exists.
Maybe a Gofundme account?

I think there has to be a certain steps to slant ratio when getting a permanent ramp for wheel chairs. Ask social services, medicare, contractor, for all of your questions. If it's medically needed does medicare/medicaid, or social service provide it? I think it has to be professionally installed. Ask the medical staff firs, then the contractors, Google it.

This is the way I find my 6 packs in my area... built in wheel chair ramps. I go to the door and politely ask.
