> San Francisco led the nation in annual rent growth this month, with both one and two-bedroom prices hitting new all-time highs, marking the highest levels in over a decade of Zumper data. One-bedroom rent climbed 18.4% to $3,790, surpassing its previous peak of $3,720 set in June 2019, while two-bedrooms rose 22.6% to $5,270, exceeding the prior high of $5,120 recorded in September 2025.

From the Zumper report. 22% gain on SF 2B is just insane to me.

But what about the desirability of San Diego? Was the decrease in rent only because of the increase in supply, or is there also lower demand?

Very off the cuff but I do see some news about shrinking population - https://www.reddit.com/r/sandiego/comments/1s71z3a/san_diego...

That says more about affordability than desirability since rents have gone up over the decade but there's been a steady trickle out to cheaper locales

Lots of people quoting basic supply and demand. People in the year 1500 could pretty reliably tell you that a rock would fall down if you released it from a height. People would also tell you that if you threw it up and away, it would go up in an arc and fall down. The innovation that Newtown and friends brought about was they made quantitative predictions about the rate at which the rock would fall down, or the arc…

Most rent payers aren't concerned with the exact function that will describe the shape of the curve for decline in cost of rent.

They are mostly interested in "rent go down", or at least "rent not go up".

That said, there are people who have studied this. You don't need Newtonian level math to calculate elasticity. Hell, we can look at how rents rise in a constrained market and make a pretty good guess what would happen if supply increases.

There are dozens of papers that have these numbers when you search the academic databases for "rent elasticity"

Incredible. So what you're saying is... we should just build more housing? Who would have thought that was the answer?

Building the house is the easiest part of building a house.

I'm not sure half the country would agree!

Notably, though, a significant fraction of people seem to believe that building more housing will cause rents to increase. So it seems like it is still important to point to data suggesting the opposite.

Housing is a unique market, because every single product in it is unique, and prices and rents can vary quite a bit.

In a city I used to live, the city decided to revitalize a section of downtown by bringing down some old small buildings and replacing them with high rises. The resultant effect was a bloom in shops and restaurants in the area. That meant that 1km^2 area became a lot more attractive, landlords jacked up rents, and existing tenants in the other buildings in the area had to move out for people who were willing to pay 2x the rent. Of course rents probably went down elsewhere in the city to compensate.

You will never get this sort of prediction from simply supply and demand. You need to build quantitative and holistic models that make predictions based on a range of factors. Then use those to make policy.

Increase in supply lowers equilibrium price? Somebody, pinch me!

A mainstream view on one side of the political spectrum that increase in new home supply(especially if high end) does not lower prices or reduce shortage. > One well-worn refrain of progressive urban politics is that new, “luxury” housing will not help solve the housing shortage. A 2024 study of U.S. voters found that 30 to 40 percent believed more housing would, instead, increase prices, and another 30 percent belie…

Those people aren’t progressives: they’re NIMBYs who learned that certain language can make it easier to get the policies they want. We have a ton of them here in DC, and you can tell by seeing what else they support: they’ll talk about affordability to block luxury apartments, flip to pretending to be staunch environmentalists to block an affordable housing project, talk about traffic or “the poor” when protesting a bike lane before pivoting to block transit projects, etc. It seems incoherent until you look at it through the lens of whether something would add competition to their future home sale or cause the city to subsidize them driving every everywhere less.

I've been told repeatedly by people who have a vested interest in maintaining high housing prices that supply and demand don't work at all, ever, for any reason, and high prices are no reason to build more housing. How do I reconcile these facts?!?

The majority of the "more housing = cheaper rent" success stories crowed about on the internet correspond with net population exodus. Austin, Minneapolis, now San Diego.

Edit: I think we should build several million more units of housing in the US. I'm salty because all the new housing I've seen is ugly shitboxes owned by national property firms that make everywhere feel like nowhere.

Earlier quoted context omitted.

That part is the obvious part. I want to know how they got all the entrenched landowners to let new builds in their neighborhoods and drive down values. The NIMBYs are usually the problem.

Unfortunately, it's not actually obvious. There are heaps of people, even and especially in the most expensive housing markets in the US, who will outright argue that supply and demand doesn't apply to housing.

I have to guess it’s along similar lines to the claim that additional road capacity leads to more congestion.
