Do you mean where the sloped walkway is now ? The walkway is pretty simple to make work for a wheel chair but the steps are the issue . You will need a ramp to the front door and that will require some real work . Is this for a permanent issue or just short term ?

Perhaps some modification on the porch area may be necessary, such as removing one side railing. You might be in an area where there are local resources to assist with plan design and/or installation. Here are some concepts you might find helpful.

Best of luck to you!

It looks like slope requirements will have to be addressed and then how to accommodate.

My dad was disabled Vet and there was a local charity group that designed and built ramps to help them. Ask the rehab professionally for contacts. To me a ramp from drive to the side of porch look logical.

If you were to use ADA guidelines you'd need to calculate the height of this red line and multiply by 12. That is how many feet of ramp you need. For example, if it is 4.5 ft you need 45 ft of ramp. That is a lot of ramp in this size yard. (Forgive me if you already know this.)

You need not follow ADA guidelines (unless for some reason your town code requires it). But you can use them as a rule of thumb. The reason why there is a 1:12 ratio is because anything steeper can be challenging or unsafe for the average user to use. So build something not for the average public user but for the person who will actually be using it.

Are they buff and strong and can manage a non-electric chair with a 1:8 slope? Is it someone with a mechanical chair that has a lot attached to the back and needs a ton of turning radius? A chair that will be pushed by another person? Will this person always come from the driveway or will the be dropped off by someone else in front of the house?

You have a lot of slope and stair height to account for in the slope of your ramp. Could one idea include a mechanical lift on the side of the stoop that may help reduce the amount of ramp needed? Could you get a curb cut where the pink arrow is and have a walkway to a mechanical lift next to the stoop?

For the price of a ramp I would consider a lift instead and paint it the same as the house to blend in since the existing ground level walkway look rather good in its existing slope.

And so we wait for the OP to answer questions , this just happens way too much We take time to help but get nothing from the OP

Second Lorraine's suggestion of a lift that can be tucked away the left of the side of stairs.

OH Rachael where are you?????

Shrubbery in front of it to disguise it.

Really!!!! Why ask if you don't want help and at least answer some questions
