s/residents/home owners have always been opposed to that. Renters would be thrilled about it, but home owners love seeing their home values skyrocket. Multiply this if they've been in the area for a while, and again if they're currently renting out their place(s).
A lower-end but not ghetto apartment in SJ is around $2200 for a 700sqft 1bedroom. This would not be in a place walking distance to a train station or to a downtown area. The mortgage on a 4 bedroom 1200sqft house valued at 800k (i.e. What most people would call a normal average single-family home) would be about $2800/month (assuming you had the 125k or so down payment). You can then rent 3 of the 4 bedrooms and end up making money on the house you live in vs flushing >$2k a month.
This is why normal people can't get ahead out here and end up moving away. The way things are is massively skewed toward home owners and property investors. Building more apartments won't necessarily help, since all the apartments built after the rent-control cut off are getting renovated or demolished to be replaced with brand new units which are "luxury" ($2800/month and up for a 1br).
Apartment places almost always have units available where I've looked. It's not like you can't find a place out here, just not a place for under about $2k a month. Apartment places would much rather rent out 85% of their units at exorbitant prices vs 100% at half that. I don't believe that adding more housing (which won't be under rent control and will undoubtedly be "luxury" housing) will lower average rents. I don't know what it would take to get the Bay Area back to rents in the $1000/month for a 1br range. I'm not even sure that it's realistic anymore.
Does anyone have a link to or know of a place built in the past 15 years in Santa Clara, Cupertino, Palo Alto, Mountain View, San Jose, Saratoga, Los Gatos, etc with units under $2k a month? My pessimistic side just thinks that adding more new apartments will just drop the price on the high end, so that $3k/month loft in the glass tower in downtown SJ might only be $2800 next 11-month lease term, or maybe only go up by 12% a year instead of 18%.
We need to do something drastic if this is to be again under control, but I suspect that due to the very large sums of money involved, the entrench interests are attempting to prevent that by whatever means necessary, and we're basically screwed until this bubble bursts, if that even happens this time.
