Another Arizonian here . . . my understanding of why few homes in Arizona have basements is due to the expansive soils here. Could be another factor in why more homes in CA don't have basements?
I'd read that somewhere around here is a home build entirely underground and it does not need any A/C at all. Wouldn't that be nice? Seems that if more homes in the West had basements it may lower the cooling costs.
