I understand that it seems to you, based on numbers, that housing can be more dense n the CA cities. But, in the areas I live in and by, they are already built out ! So, maybe they could have been developed denser, but at this point, you realy cant take an existing neighborhood with large lots and redo it. They have done it on new houses, and in general, it is horrible, yards too small to grow a garden in !
A city by me, they are, in theory, allowing everyone with certain sized lots to build a second unit in their back yard. With many strings attached, like trying to make it so that they can only be rented for below market rent as affordable housing. So, not much of that is done, because why would anyone want to give up their garage or backyard to a person or people that they dont get to choose for money that they dont feel is worth giving up the privacy for ? There are quite a few unpermitted, illegal units done like that though and rented out for market rates, or, at this point, they are air-b-n-b, as that pays well and has less tenant problems and air-b-n-b short termers do not call building dept on them.
I do not see too much building code problems, (some by me, but it isnt related to topic here as coastal commission doesnt have say over much of CA). What I have seen, when I lived over the hill was building codes holding down sizes of remodels, barely. And for good reason ! What I also see is unbearable pressure by the state, to everyone except Marin county, to try and force building of new units, even when all land is already built up. I also see rezoning. I also see multiunit high ( well, relatively higher, anyways) buildings going up, usually subsidized, and still unaffordable. Units in the city subsidized condo place went vacant for a very long time, as it was expensive. Because land was expensive that it was built on ! A new hi-rise being considered is in a downtown area of a city, totally built out and land locked, that has no existing structures over 3 stories, under pressure from the State considering a 10 story multi-unit. And no-one wants it, there is such severe outcry, I doubt it will be done. The rezoning of a commercial area to allow housing is being done.
I realy do not understand why outsiders consider it NIMBY-ism for a community to want to stay being a small or mid sized community ? Why should people have to cave to developers who make money and ruin an area, so the developers who do not live there make money, and the people who live there have a reduced quality of life ? The people who live in the communities, the ones who have to live with the consequences are the ones who insist on building codes that preserve the communities they bought their homes in. Makes sense to me.
How much is enough ? When is an area "full" ? Do people have a right to move wherever they want to and then demand housing and services to be provided by the existing population ? Should companies build facilities where their employees can make it, instead of an area with no housing ?
I love fairness in codes and repealing the ridiculous, and there are some. But, that is not going to make more housing here. The fair codes will fairly not allow single family neighborhoods gutted. The few areas hampered by over-zealous reviews are realy not many areas, as that is only done to unbuilt areas and we realy have very little to none unbuilt -- so those 2 items are not going to make enough housing in the greater SF bay area for all comers.
As I mentioned before, they have a "solution" and that seems to be making Merced, etc... into defacto bedroom communities for Silicon Valley via the new high speed rail. Not that I like it. But, the developers will make their money, and the stae will point to new units...
