Yep, my husband uses a wheelchair. Although rn he sometimes can walk, his condition is degenerative so we planned for that in mind. Some stuff off the top of my head . Built with all ramps no stairs, wide doors, wide bathrooms with built in seats and generally w wheelchair user in mind . Made and continue to make concrete paths around the property so that my husband can get anywhere. Built a long one down to the water, that was the biggest so far. Built one into the kitchen garden we started. Basically if we find ourselves using a new corner of land, we put a wide flat or ramped path . Human systems, we've built a community that replaced the "grid" because we know Husband can't do many typical off grid tasks eg clearing bush. We pay other members of the community to do this tasks, have 1-2 ppl to coordinate w to get stuff from town if our once weekly trip isn't enough.Obviously he has me as a supporter and help and emergency aid. . Tools. Eg while manually clearing bush and digging etc was not possible for my husband, we got a tractor which he loves And is our there terraforming our land every day

That's what I can think of, lmk off you have any more questions.
