New York City winters are not for the faint of heart. When temperatures dip into the single digits, it can feel impossible to get through the day. However, things are even more difficult when the heat does not adhere to legal requirements. Each year, RentHop reviews 311 data about heat complaints to find where renters are stuck in the cold most often. For some, these conditions lead to deadly supplemental heating practices. 
The Department of Housing and Preservation defines October 1 through May 31 as “Heat Season,” when landlords are required to meet certain temperature requirements in the apartments they oversee—but all too often this isn’t the case. Check out RentHop’s interactive map to see how many heat complaints your neighborhood has received and decide if it’s time to give your landlord a call to crank up the heating in your building!
