I have mixed feelings about this. I’m visualizing a small town with one pool and limited resources. They should be exempt. I’m thinking of my community though which has multiple pools. One at least could have one of these devices and those special stairs for getting in and out (I’ve actually used those on days when I’m a bit stiff). My fitness center has three pools. One of them has this device and the stairs. It’s the indoor pool. I saw a young man in a wheel chair though who had the upper body strength to swing himself out of the chair and into the water and back out again - no legs. But in another 20 years, what will he do. Motel 6, nope. Small one pool towns nope. Maybe local option and market forces but not federal government. That’s what I’m thinking.
Maybe such laws shouldn’t be retroactive, or, ex post facto, but apply to new construction only.
As an example, an older home might have exposed knob and post wiring for electricity. Generally it is OK to maintain the components, from an electrical code perspective but no new home construction may be constructed this way.
How about a return to private property?
