You can sue for literally any reason you like in the US. Doesn't guarantee success of course and you might even end up being liable for court costs in addition to your own lawyer (if you hire one) but even if the lawsuit fails, being sued is a pain in the ass to begin with so why even open up the opportunity? Just shovel the damn snow or hire someone to take care of it especially if you are renting to disabled people.

Slumlords will downvote but fuck those assholes.
