someday the folks on the west coast will realize they have to come into the 21st century, you cannot have little two story homes with backyards there forever, like it or not it will have to look like Singapore or Hong Kong some day, it may be years and years away but they must start supplying housing. Maybe not on the coast itself but somewhere near the urban areas they will be forced to start building high rises. San Francisco is doing it downtown, and very poorly as I last recall but they are trying at tremendous added cost of course.
Already started happening here on the SF peninsula. High-rise housing going up all around. Neighborhood groups here in South SF been fighting the city council over planning that is allowing towers to be built all around our town. State gov't overruled locals and is mandating that developers can build tall and locals can't stop it. We have had multiple high towers built where there used to be only two-story buildings. City rezoned much of the city to allow multi-family high towers where zoning previously only allowed two story single-family residential. Spillover from SF, now forcing growth in SSF in San Mateo County to the south. Our formerly sleepy suburb is getting crowded and having traffic jams. Construction is everywhere. Part of the price for being in tech-savvy Silicon Valley.
