If the problem is zoning that’s blocking density then why is the density of Cupertino (5,300/sq mile) almost double that of Houston (3000/sq mile)? Houston is the example of why cities need zoning regs. No one wants to buy a home and have a high rise erected next to them. Cheap housing comes from cheap land and cheap labor. Cupertino had neither of these and will continue to be expensive as long as there are companies paying high salaries in the area. It doesn’t matter if you allow high density housing if it costs $3M/single family home to acquire the land.
