All the new construction I see in the south bay area are 3-4 story townhouses, condos and apartments. However they are still going to be expensive given the demand. However the bigger problem is transportation. The roads are getting worse during peak rush hour and I don't see much room to improve it further. I've been a long time resident of the bay area and a lot of neighbors are complaining of the traffic leaking into the surface streets to shortcut the packed freeways. Some are voicing complaints to protest additional housing until the transportation is improved.
