I agree that landlords need to be held accountable to ensuring livable standards for their tenants- especially when it comes to something basic like heating. Alas, many do not. Whether this is due to old heating systems, neglectful supers, or both, I don't think that enforcing temperature minimums (and unnecessarily high ones at that- 72 when it's under 58, really?) would productively address this issue. If anything, it would create more economic and environmental waste. Instead, the city should consider investing in more cost efficient, heat trapping infrastructures and materials.
