They are responsible to keep an egress safe.

That said generally speaking there is a pretty wide tolerance for the timeframe - it will vary by city. Pawtucket for instance is 12 hours of "daylight" which I guess could extend more than 1 day but generally what they mean is that if the snow stops overnight the property owners have the day to clear it. If the snow stops at 1 PM, you have to clear it by 1 AM. That kind of thing. Every town is slightly different. RI general law I believe in 24 hours after the storm clears - this applies to things like sidewalks and businesses state wide.

HOWEVER, since the fucking cities don't bother enforcing this stuff on busy pedestrian streets and barely do it on their own properties, I think it will be harder to get code enforcement on your side than you think. Sorry that's just reality.

Tenants with special time needs are often left on their own, which for most storms means you have to figure out how to get to work in the morning after an overnight storm. That's just life. Yes, this law protects you if you have a slip and fall but getting injured and going to court isn't that fun either.

They should at least provide you with the means to take care of it yourself when you need to. Just a bit of ice melt this morning's ice would have been fine. I would request that and let them know about today's situation.
