I don't know what you mean, but I belive we're talking about "wheelchair ramps" at street corners

some of the laws mandating that type of thing specify "if/when you renovate something, you need to bring it up to code, otherwise you can skate on the code"

this affects a lot of the little tiny shops in NYC. if you change your facade or bathrooms, they need to be made accessible. however, it's not the cost of renovation, it's that accessibility can entail many many square feet of space that is now inaccessible-to-make-any-money-from, making the rent much more unaffordable. so, renovations are still done, but meticulously match what any previous plans on file would look like.

Around here real estate listings are starting to not do interior pictures because the towns are known to predate on them for "hey you didn't get a permit for that bathroom reno" type crap.
