This is a common question Massachusetts tenants have when the winter rolls around in New England. Here is a good answer to the question provided by the Massachusetts Attorney General’s Office:
"A landlord is required to keep all doorways clear of snow so that tenants can come and go, but is not required to shovel the walk or plow the driveway or parking lot. Check your lease for any terms that cover snow removal to find out if your landlord agreed to remove snow from any of these other areas. For more information on your rights as a tenant in Massachusetts, please contact the Consumer Hotline and ask for our brochure."
Of course, the above answer only skims the surface regarding Massachusetts landlords and their obligations to remove snow and ice in Massachusetts.
