“Dear PoPville,

Does DC have any laws for rental properties regarding how much windows have to open and air flow? I’ve recently moved into a studio that I love but I only have one opening window and it only opens a sliver. I barely get any moving air or temperature change.”

Interesting question – anyone know if there are any regulations for windows opening?
