6 years ago I broke the neck of my femur and had it repaired. For a month or two afterward I had to use a walker. Negotiating one stair step with a walker is easy. Two steps is almost impossible so I had a carpenter build a step extension so that I could get into and out of my front door. Within a week I received a letter from the condo association telling me that I had a "non-approved exterior modification". That's why we need ADA laws.
