Modular pod-based housing may be an option.Another good step is rethinking housing construction regulation and red tape. You can’t build this way, you can’t do this without that and that and that, you can’t build there, you can’t build up etc etc etc etc. Housing is like anything market related, supply and demand will be a big factor in cost. The lack of trying to meet supply in favor of other, ahem, priorities has been significant and going on for many years. (Upward building I n Silicon Valley is semi hampered by SJ Airport being toward the valley’s middle).
It caused a huge outsurge of house buying up 680 then eastward down 580, even reaching Tracy/5/Manteca, up Vasco as well as on the other side of the valley down 101 to Morgan Hill and Gilroy and beyond. Traffic gridlock hell is what I called it.
They want to maintain the green belt then emphasize big tax incentive options to builders to build upward. Lord knows they’ve tax incentivized Cisco, Google, Apple, Intel, Adobe, Ebay, Facebook(they picked up Sun Micros sweet bayfront old campus) and likely many others.
We can also make it more sustainable by incentivizing consumption of insect protein, by taxing mammalian protein higher than a normal FANG dev can afford to consume. Also, centrally controlled thermostats and water faucets to preserve precious water and energy resources.
