Yeah, there’s this too:

However, a small but growing number of U.S. states, cities and counties have adopted legislation that impose maximum indoor temperature standards on rental housing. In the last five years, six U.S. localities, including New Orleans and Clark County, Nevada, have adopted such cooling laws, compared with just seven in the previous two decades, according to Reuters’ review of property codes and interviews with more than a dozen policymakers and housing officials.

But it shouldn’t have to be done at that minute of a level. State or federally it could (I argue should) be guaranteed as a basic necessity, just like water, power, sewer.
