It’s bullshit that people who would prefer to live in studio or 1-bedroom apartments are forced to live 3–5 roommates to a house with all available rooms converted to bedrooms (for which the same land could easily fit several apartments) because the zoning doesn’t match demand, and otherwise it’s too expensive to stay anywhere within commute range. Especially bad when one of them wants to start a family but it’s simply impossible because giving up space in a rent controlled unit makes the whole region entirely unaffordable.
Unfortunately, it's incredibly good politics to be for "real families" and against young single antisocial techies who want to live alone. One of the restrictions on multifamily construction is a minimum proportion of 2- and 3-bedroom units.
