I'm also surprised that you would still think the math does not apply. A 100 unit building taking up the space of 12 SFH $1.5mm homes will sell many more $800k 2 bedroom apartments comparing what houses and apartments sell for Build about 1000 of the buildings close to bart and muni tunnel stations and you would get 100'000 units for the price of 3000 SFH / in law units and a larger city budget to fund the new required transit system capacity.
