These new houses will probably be at least as expensive as the average house there just due to the nature of single family houses in the Bay Area. Cooking during the whole year and heating during the winter will cost more. Those winter months will be hundreds of dollars more (possibly hundreds of dollars more per month). The people living in these places can probably afford it just due to them being able to buy the house itself. Makes better insulation, solar panels, and houses designed to soak in heat if desired more attractive.
