If everyone who wants to pay $5k a month to live in NYC is able to; I’ll be super happy and pleased for them.

> bunk beds… $5000/month

The market prices full one-bedrooms at less than this in most of Manhattan. Flophouse beds would cost a fraction of this and they would get cheaper the more of them you have. They’d also slow the growth of rent price in NYC.

Let’s take your example at face value. Suppose Manhattan added one million beds to its existing ~3.8M bedroom housing stock via the “missing middle” housing that you described, perhaps over the next ten years. These might have small private bedrooms and shared kitchen/office/bathroom facilities. They might even include dorms, but I’ll focus on single-room occupancy units. You’d get the space for this from some mix of re-developing office buildings or upzoning or re-developing low-slung buildings.

The rent of these single-room occupancy units would be a fraction of the rent of a normal place. The people living there would be far less rent-burdened than they would have been otherwise, freeing up more income for consumption or savings/investment, boosting economic activity. Some of them would be new residents, whose income taxes (if they pay them) and spent dollars/sales taxes would be a net benefit to the city budget. Some of them would otherwise become transiently homeless due to affordability concerns, which would be destabilizing for them and expensive for the city due to homeless program spending.

Others would be people who currently live in apartments but would move to these units because they prefer cheaper rent, greater privacy (they might be sharing a room today), a newer building, or the greater efficiency of having multiple bathrooms. Maybe right now they are sharing e.g. a four-bedroom one-bathroom apartment with three strangers in Hell’s Kitchen for $1400/month. These people would otherwise be in the housing market for a full apartment, and removing them leaves more full apartments for people who want to occupy them, either alone or with roommates. Ergo we get downward pressure on full apartment rents.

The flophouses and dorms and SROs were a key part of the housing market that kept Manhattan more affordable and therefore livable in the 20th century, when density was up to 40% greater than it is now. It was deeply shortsighted to get rid of them. The idea that we should downzone even further makes no sense to me; you get to decrease affordability and decrease the economic benefits of agglomeration to the local economy at the same time, all so… there are fewer people on the subway, I guess? I disagree with the “too much density” argument on its face anyway. Density has clear economic benefits via agglomeration and productivity gains; diverse and dense housing stock via upzoning increases affordability via supply/demand and filtering effects; and the way you manage density is through appropriate infrastructure spending on housing, services, and public spaces which—you guessed it!-becomes cheaper per person the denser you build. Seoul has twice the density of Manhattan.

I live here. The thing making Manhattan unlivable is that a one-bedroom is $4500 in the east village due to not enough supply. Fix the housing costs by building more of any and all kinds of housing and then we can deal with the other problems via better governance and increased tax revenues. There’s nothing we can do otherwise that isn’t just rationing or some other bandaid solution.
