How long of a time frame does a landlord have to remove ice/snow?

[Samuel J Claeson]

Hello BP members,

I was not able to immediately salt the driveway this morning, and I received a quite threatening text from my tenant about the "icy" driveway ("...my brother in law is a lawyer!....").   I personally did not feel it was unsafe to walk on the driveway or sidewalk, but I immediately called my handyman to see if he could help salt the driveway because I was already at work (shout out to Proper Upkeep).  While texting my tenants back, I imagined a court judge was looking over my shoulder, and told them that "someone would be there to salt the driveway in 45 minutes and to wait to walk on the driveway until it is confirmed that the sidewalk and driveway are salted. If you must walk on the driveway or sidewalk be cautious."  

My question is this: how much time does a landlord have to remove snow/ice from a rental property?  Is it 24 hours? Is it immediately?

I know it would be best to ask a lawyer, but I'm curious about other landlords/property managers that provide snow/ice removal. 

Thanks in advance!

Sam
