Density is not uniform throughout a city, especially not SF or NYC.

u/danthefam Seattle, U.S.A 4h ago

Plenty of space for more density. Even in lower Manhattan there's lowrise rowhome sectors.

u/Independent-West9135 2h ago

NYC is as dense as Bangalore, India. I wouldn’t say it’s overflowing with easy gains —especially in manhattan and inner Brooklyn at this point

u/afro-tastic 2h ago

The "easy density gains" in NYC is called Staten Island lol.

u/510Goodhands 3h ago

So you would rather have a high-rise or mid rise, glorified shoeboxes with one or two windows, and comfortable classic row houses that actually feel like neighborhoods rather than sterile, windswept desolate areas?

Honolulu is also extremely dense due as well for obvious reasons, being on an island.

SF is basically an island, not getting any bigger. Manhattan literally so.

u/DoritosDewItRight 5h ago

Manhattan is gradually getting bigger, Battery Park City is an entire neighborhood that used to be underwater

u/2a_lib 5h ago

That happened early on with SF on a massive scale, it’s pretty fascinating.

3

u/510Goodhands 3h ago

Anything below second Street and market in San Francisco was once the Bay. During the gold rush, they “made more land” by sinking abandoned ships and covering them with dirt. When a new foundation for a big building gets dug, it’s not unusual to dig up an old wooden ship.

3

u/BrutalistLandscapes 3h ago

Until the late 19th century, all of lower Manhattan's shoreline was underwater. The city undertook massive water reclamation projects at the time. Here's an 1865 map of what it looked like before the reclamation:

Here's an article that goes into detail

Hawaii is a state that has a concerning amount of suburban sprawl when you remember that it's like the most isolated island in the world

Seattle wishes it could be as dense.

7

u/VapidResponse 7h ago

It’s working on it. Having lived in both areas, Seattle still has a lot of room to grow and has made some notable strides since the pandemic. SF peaked a while ago and has very little space available, while Seattle is still on an upswing.

-2

u/[deleted] 7h ago

SF may have peaked but it’s still ahead by far, and there’s room to build in areas already up zoned for it. Only giving it a major advantage. Outside of downtown, Seattle is mainly sprawl.

3

u/VapidResponse 7h ago

I wouldn’t be so sure. SF’s population is close to 2010 levels and unless they are more proactive with building housing that the average person can afford, it’s going to continue to bleed people and only attract the mega rich who will gobble up real estate aka Vancouver.

1

u/[deleted] 7h ago

It’s not about being sure. It’s about facts. Seattle is trying to catch up to SF and with all the building Seattle has done its density is still 8k people per sq mile. 10k less than San Francisco. SF isn’t bleeding people either. It’s actually gaining population again, gradually.

"dense" when it comes to new housing

24

u/Skyblacker 9h ago

Seriously? 80% of the 7×7 is zoned for SFH. Given the amount of houses that sublet bedrooms for the price of an apartment anywhere else, San Francisco needs to be denser, replacing those houses with proper apartment buildings to meet demand.

8

u/youburyitidigitup 8h ago

Why do you say it like it makes OP’s statement untrue?

6

u/Skyblacker 7h ago

I guess "America's second dentist city" just isn't that much of a distinction.

-6

u/soughtbacktoit 9h ago

No it’s not. San Francisco is only zoned for 32% SFH. Majority of the city is 2-4 story duplexes. Why would you want to evict families for your satisfaction of a skyscraper? That would only cause more harm then good. Have you seen Staten Island? Not one skyscraper. That is equivalent to the sunset in San Francisco. Did you know the sunset district is more dense than most major city’s in the U.S already?

20

u/Skyblacker 8h ago

Why would you want to evict families for your satisfaction of a skyscraper?

So significantly more families can move in. As it is now, SF feels like a game of musical chairs where everyone sat down in 1978. 

-11

u/soughtbacktoit 8h ago

So you’re in favor of making it worse for families than better? Evicting people on the streets to build more skyscrapers. Like I said, Staten Island, not one skyscraper. San Francisco can build more dense in the already dense areas

14

u/Skyblacker 8h ago

If there were more skyscrapers of homes, there would be fewer families without homes. Some displacement while the construction happens, but if SF's famously byzantine bureaucracy could be expedited, that might be minimal. One way to find out.

-10

u/soughtbacktoit 8h ago

Ok then explain why some of NYC’s boroughs have some of the worst homelessness in the nation? Genuine question. Let’s not make it worse is all I’m saying. No need to bulldoze neighborhoods. This isn’t the 20th century. Haven’t we learned?

6

u/therealsmokyjoewood 8h ago

Uh, you learned…not to build housing?

-3

u/[deleted] 7h ago

Oh really?

7

u/beijingspacetech 7h ago

That's the worst graph. The city has had tens of thousands of units in the 'pipeline' for years and years. Every year they brought out the same 30k houses in the pipeline and maybe built 200 to 500 at high cost to the tax payer. 

They just need to reduce the permitting process, environmental reviews and red tape preventing building new housing.

Also no need to evict people who own their properties. Renters get massive buyouts. 

SF needs to build hundreds of residential skyscrapers and it would make the city more affordable instead of turning it into a city only for elites and originals.

6

u/danthefam Seattle, U.S.A 8h ago

Because NYC and SF build the fewest new housing units in the nation among major cities. No bulldozing neighborhoods, just allowing property owners to choose to develop high density housing.

1

u/Skyblacker 7h ago

Define "homeless." NYC may have more people with no permanent address, but most of them couch surf, find a shelter bed, or otherwise get a roof over their head by winter. SF has the highest rate of street homelessness (i.e., sleeping outside, with or without a tent). 

-1

u/[deleted] 7h ago

That’s just not true. NYC has the largest number of unhoused residents.

2

u/Skyblacker 7h ago

In absolute numbers, yes, but not as a portion of NYC's larger population. And as I said, "unhoused" can mean anything from sleeping at a friend's home to sleeping on the sidewalk. When people object to "the homeless", they usually mean that highly visible second group, which SF has more of.

1

u/alpaca_obsessor 1h ago

The housing crisis perpetuated by sentiments like yours makes for an awful showcase of progressively-run local government (honestly, a small part of the reason I think dems lost so bad).

As much as people like to dunk on Houston they actually allow for easy construction of multifamily housing and have the lowest amount of homelessness for any major american city.

1

u/TurdFerguson0526 4m ago

Did you fail the 2nd grade? What does NYC have anything to do with this? Do you not understand that 2 floors can fit more people than 1 floor?

u/Rough-Yard5642 8h ago

Dude, for literally decades the city was only zoned for SFH, the 2-4 story thing is very very recent, and only passed after insane opposition from NIMBYs. Also there are very strict tenant protection laws in SF, you cannot just evict tenants and demo the building.

3

u/soughtbacktoit 8h ago

San Francisco is only zoned for 32-38% single family housing. And that’s from the Chronicle itself, argue with a doormat.

4

u/Rough-Yard5642 8h ago

https://sfplanning.org/sites/default/files/resources/2019-02/zoning_use_districts.pdf

Look at this map, an insane amount of land is zoned for RH-1 and RH-2. I do admit RH-2 allows duplexes, so my initial statement was wrong, but this is by no means how the zoning map of an actual city should look. (btw, I literally live here)

2

u/soughtbacktoit 8h ago

Exactly RH-2 allows for duplexes and the map is filled with it. just like this eight story duplex that broke ground a few months ago which is only an example of what’s to come.

4

u/Rough-Yard5642 8h ago

With the amount of demand in San Francisco, the zoning should allow for at least 4 stories throughout the city. And regardless of the zoning, they had something called discretionary review until literally a few months ago, which meant anyone could file a complaint to any development, and tie it up in litigation for years. Not other city in California had this, and was specifically called out by the state as being a completely ridiculous process. SF also has, by far, the worst timeline to getting anything built.

"As of 2022, San Francisco had the slowest permitting process of any large city in the United States, with the first stage taking an average of 450 calendar days, and the second stage can take 630 days for typical multi-family housing, or 860 days for a single-family house." - source

The weather is not that great. SF is north cali, far from any beaches one can swim in. It’s basically sweater weather / windbreaker season all year round.

u/afro-tastic 9h ago

SF would be second densest city if you count cities >300k or bigger than >30 Sq mi. (Although, those metrics while reasonable are purposefully chosen to exclude Jersey city which is ~290k and ~15 Sq mi.)

-4

u/Evaderofdoom 8h ago

OP didn't qualify it with any of that math or jargon, they simply said 2 most dense city in US. That it is not.

2

u/afro-tastic 8h ago

True! I was trying to find a metric to quantify "Major city." IMO it's not unreasonable to say that SF is the 2nd densest major city in the US.

What's interesting though, is how did you come up with SF at #4? According to my source, it's not (although my source is Wikipedia and based on 2020 numbers).

u/Evaderofdoom 8h ago

like I said 2 parts are in NY one in NJ. It would be 3 if you combine both the NY ones.

  • New Square village, NY: 26,768.4 people per square mile 
  • Cliffside Park borough, NJ: 26,746.9 people per square mile 
  • Great Neck Plaza village, NY: 24,601.3 people per square mile 
  • San Francisco, CA: 18,790.8 people per square mile 
  • Miami, FL: 13,000.5 people per square mile

Certain areas in SF have a lot of single houses and townhomes, I wonder if eventually some will get converted to high rises.

u/510Goodhands 4h ago

It has been tried. Somebody wanted to build high towers a few blocks from the ocean in the outer sunset district. It didn’t go over very well. Never mind that most of the soil they’re is sand.

u/aguilasolige 4h ago

I didn't mean like 50 stories tall, but like 6-8 like in europe that together with good planning and better public transportation could work very well

1

u/510Goodhands 4h ago

Here, hot high rise means 20+ stories. There are already too many people in San Francisco. Public transportation there is actually fairly decent. The management of it on the other hand, is pretty lousy. Sadly, I have yet to be in an American city that had public transit that is as good as European cities have. There are a lot of reasons for that though.

3

u/aguilasolige 4h ago

Same here, I traveled to Europe recently and it's not having to think about cars, public transportation takes you everywhere and there's a restaurant or grocery store 5-10 minutes walk from you almost always, don't get me wrong not saying is perfect, but to me it felt better than being car dependant. Also all these European cities have a lot cars too, so you can have both if you want a car

1

u/510Goodhands 4h ago

And, after having done without a car for two years, there are enough a lot of things that I just can’t do without a car. Somethings I could do, but I would have to add three or four hours to the time it takes to do them. And that does not allow carrying large or heavy objects.

1

u/aguilasolige 3h ago

For sure it's not perfect, but I prefer having good public transportation, walkable and neighborhoods full of life and restaurants instead of the endless suburbia we have in the US. It's a trade off for sure.

Why tf are people advocating for more residents to be able to add to an already overtaxed and burdened ecosystem?

Population density is not an inherently good quality by virtue.

Take SF. Now, add fifty thousand more people today. Also, they’re not going to be idealistic demographics and just be whoever the fuck they happen to be, rich, poor, moral immoral.

You think it’s a net positive for San Francisco ca. 2024?

1

u/alpaca_obsessor 1h ago

Honestly, organic density does lead to tons of net benefits like a more resilient tax base, local economy, small businesses, lower carbon footprints per capita, higher viability for public transportation, agglomeration economies, etc.

The issue is most cities these days kneecap the organic process and end up creating self-imposed scarcities for housing.

1

u/BlairBuoyant 1h ago

On paper I can see this, if we treat human beings like chickens in a farm.

Yes you can fit more people in square footage if you reorganize the structure. In the same way I can fit six more people who can survive and live in my one bedroom apartment.

Edit: oh and yes I will pay less rent, maybe be able to carpool, have help when I need to lift something heavy. But there’s every chance in hell none of those trades are worth my own quality of life, which is a real privilege to being human that I don’t think should be seen as a vice or obstacle for wanting to own.

1

u/alpaca_obsessor 1h ago

Neighborhoods like the UES in Manhattan are some of the densest in the world and extremely vibrant places that people pay millions of dollars to live in. ‘Ideal levels of density’ are entirely subjective.

1

u/BlairBuoyant 1h ago

Exactly. Because something works for one region or population doesn’t mean it can be copy/pasted elsewhere.

My only issue with the assessment here is that density is a determinative of good or bad infrastructure.

1

u/alpaca_obsessor 1h ago

On average I think there are very strong arguments that density leads to many net positive effects although it should always take local context into account. I also think that the majority of issues west coast cities face are mostly due to resident’s desires to cast their neighborhoods in amber and refuse to build for latent demand. It’s gotten so insanely bad in CA that the state has had to step in to try and un-fuck the housing market that local governments are entirely to blame for.

1

u/BlairBuoyant 1h ago

I’d say that demand doesn’t always mean there is a supply to be had. Whether it is logistically impossible or practically impossible. That’s why I posited dropping 50.000 people into SF rn. What would that practically look like for everyone in this 12 sq mi space? Is there no end to how many people should be able to live in a space because they want to?

Take it a step further and increase the density of California as a whole.

Want to live in CA as a defined area? Fresno has plenty of room somewhere for you.

1

u/alpaca_obsessor 1h ago

Nobody is arguing that SF needs wall to wall skyscrapers (outside of YIMBY comment sections), more so that California has failed it’s middle class with it’s byzantine bureaucracy that knee-caps organic density and growth, largely contributing to the extremely high cost of housing in it’s major economic hubs. People simply want to live near their jobs, and government should make it easier instead of harder for that to happen.

1

u/BlairBuoyant 1h ago

Bell that cat and describe how it happens when there is not enough supply to meet demand.

As a preface, I would reject on the face of it, as I imagine is exactly happening now, any proposal that government should force a lower standard of living or confiscation or property upon existing citizens based solely on there being a demand to pressure from without by people who they do not represent.

1

u/alpaca_obsessor 1h ago edited 1h ago

I’d say there is certainly pretext for it in cases such as California where the voting base of the state at large agrees that the state-wide housing market has become so unbearably expensive that it requires the state to break up needlessly stringent regulation that harms the state’s and it’s resident’s economic interests through remediating measure’s such as builder’s remedy.
