When America banned real toilets, 5 gallon flush toilet sales skyrocket in Canada where Americans brought their own back home. Americans will buy them outside SF
I’m guessing a permit is normally pulled there, for any new HVAC systems installed. Who am I fooling...a permit is probably needed in SF to swap out a light bulb. Anyway, under-the-table installations would have to occur for new gas heaters because SF wouldn’t issue a permit. That would turn into a real mess.
