That implies that the code cretins would actually make a carve out for it. If I go to the trouble of jumping through all the state / county / local building code applications, I’m just going to build a 20kw capacity 48v solar array with a dual inverter that supports 240v and have the power company (government monopoly) as backup / battery top-up.
My point is, that this is really unnecessary. Shoehorning the general public into electrification isn’t the answer here. And it goes far beyond just my small needs as a residential subscriber. Commercial breweries, restauranteurs, and everything in-between, use gas because it is far more efficient, cheaper, and suitable for their individual applications.
Choice, is the essential thing here. Let the market sort it out. If the market can make a compelling argument for electrification, that’s the way people will go. But for now, I’m unconvinced.
(btw — I lived in Berkeley for years, and houses that were gas grandfathered were especially sought after. Government diktats just create perverse incentives.)
