> we'd prefer a 3 bedroom but they DO NOT EXIST

This seems to be an absolute epidemic across the state. Same with condos. It's like they assume that apartments of any kind are only for single people and maybe a couple with one child. In other words, people who are dragging the fertility rate down toward 50%.

When I pull up Zillow and look at rentals across a huge swath of the East Bay, there are 8,309 apartments listed (I filtered out houses and townhomes). I add one filter: 3+ bedrooms. The number drops to 784. Fewer than 10% (!) of apartments listed have 3+ bedrooms. (Also, a quick spot check of these seems to show a nontrivial amount that are actually just houses with faulty metadata.)

This puts a tremendous burden on low-income people, to have to foot the higher cost of maintaining a home and/or of an absurd commute, just in order to have enough space[1] to have more than one kid. That, or overpay to compete for one of the few bigger apartments, many of which are "luxury" oriented.

Meanwhile, the high-income can afford a house or a luxury 3br apartment, but they are mostly high-income because they've deprioritized family, putting in 10+ years of being DINKs. In my circle of upper middle class tech types, many of them are 35-38 before having their first kid. 1 kid is much more likely than 3 for people starting in their late 30s, so this drags down fertility rates even among the "high income" subgroup!

[1] I know opinions vary on whether it's good and healthy to have kids sharing rooms, though imho I don't want a son and daughter forced to bunk together as they get older, and calls to 'just share rooms' is giving "Own nothing and be happy."
