Yep, I took a wild guess that they were American (possibly Canadian) because they’re on sh.itjust.works (hosted in NA) and the time they’re posting lines up with those time zones but you’re right: laws vary from location to location.

All states are subject to the Americans with Disabilities act (which is federal), so if they’re in America, it really is on the landlord to provide them with accessible housing.

Additionally, if anyone slips on a property, the owner of that property is legally liable (though in theory, insurance would cover most of the costs). If the owner refuses to pay for the resulting injuries, they can be sued in civil court and will likely lose.

Edit: Downvote all you want but thems the facts, clicking a button on the Internet won’t change it.
