I use to live in a home where the front door opened up into a staircase which went to the living area, the first floor was commercial space, not residential. What would this hypothetical elderly visitor do then? I think accessibility is fine and dandy in public spaces, but the line between accessibility and safety becomes quite clear when you begin considering private residences. There are all manner of perfectly normal objects, appliances, and situations that can become dangerous in hypothetical situations involving disabled visitors. Hell, just look at bathtubs: generally considered benign, but potential deathtraps for hypothetical elderly visitors. Nobody is likely to replace their bathtub with a no-slip walk-in bathtub just because an elderly person is visiting, should we mandate that all new structures be build with walk-in tubs? In the context of private residences, safety issues are ones that really present an equal-opportunity risk. Mandating circuit breakers is a clear-cut example of a safety issue, not an accessibility issue. Something that is done solely for the sake of the disabled is a clear-cut accessibility issue. Stair lifts, ramps, and accessible nobs are all accessibility issues. They do nothing for the safety of the general population; they should not be framed as safety issues.
