More housing is absolutely the answer. But your cause is wrong.
The impediment to housing in California is capture of land use policy by homeowners and landlords. We should expand the category of home builders beyond developers, but developers make zero money when they are not building. So developers are not holding back housing in California. The few remaining developers in California tend to be more land bankers than developers. But if we made the process for decelopnrt straightforward, then small builders and contractors could build all sorts of projects. At the moment the process is so complex and difficult that getting approval to build on a site is a hugely valuable financial product that increases the value of a parcel of land significantly (though necessarily less than the cost of getting that approval).
The reason we do not have enough housing all comes down to that NIMBY neighbor who doesn't want to allow apartments anywhere nearby and who has also been given lots of wrenches to throw into the process of approval. We don't have that sort of approval process for single family homes, it's a night and day difference. Anybody is allowed to build a massive mansion without any community input, but for anything more affordable, neighbors can veto it, and do.
