It's good to promote home ownership if the disabled person is able to maintain the property, but one thing you have to keep in mind is what happens if it snows? Whose going to mow the lawn? I'm not against building individual detached dwellings, but in many cases an apartment setting works the best for many disabled people, including myself. Some of the biggest issues for a person in a wheelchair for example are having ample room to maneuver within the living space, and having storage for items such as food, clothing and cooking implements within easy reach. Things for the blind and hearing impaired are also an issue, such as strobes for fire alarms and braille markings on elevators and stoves.
