In the People's Republic of Berkeley, our City Council patted themselves on the back in March 2025 when they passed similar laws.
Then they got sued by the company that was targeted, and immediately waffled and canceled the ban.
What's insane about all of this is that we also have Rent Control. There is no greater price fixing mechanism than Rent Control. Rent Control ensures that all landlords must seek the highest possible rent, because they are (potentially) tethered to it for life (of the tenant).
So if you create an economic system where sellers never will allow prices to go down, why bother banning price fixing -- its practically baked into the housing code.

Why would landlords not seek the highest possible rent without rent control?
Aurornis 4 hours ago [-]
Under rent control the highest possible rent is set by laws. If you fall behind on the allowed rent increase you’re usually not allowed to catch up to market rate later, such as when your tenant leaves and you put the unit back on the market. So to avoid getting stuck at below market rate with no legal way to catch up, you have to take the maximum allowable rent increase every year. In some situations it’s better to leave a unit empty and wait for someone be willing to rent at the rate than it is to lower rent, because the consequences of lowering rent will stick with the unit for years.
Without rent control, rents can be kept constant, moved up, or moved down without having to consider the consequences for years to come. The ceiling is set by the market rate, but there isn’t a function driving all of the landlords to raise by the annually permissible maximum so they try to discover it instead.
Rent control is instituted in cities that have constrained housing supplies, so the demand is there. Landlords switch to raising rents in unison by the maximum allowable amount every year because that’s the only way to operate.

I live in NYC, which has rent control, and the idea that a landlord would otherwise lower rent is hilarious.
Landlords raise rent by the max allowed because they can. There is no “catch up” because the purpose is to protect renters against huge jumps.
I think rent controlled units that sit empty should be subject to a tax based on an escalating percentage of the market rent. You can own property to rent out, but in a city with a tremendous shortage of housing, you need to rent it out.
I lived in a building with affordable housing units and management decided they would rather not rent them out at all. Horrible.

New York’s rent control works differently from the Bay Area’s. It’s absolutely worth it to just raise the rent on a Bay Area unit if it’s rent controlled even if that means it runs empty. That isn’t usually the case in New York.

They would just be taken off the market and then relisted later.
Forcing people to rent their properties and also forcing the price isn’t something I can get behind. People need to be able to choose what they do with their property.

In a city or country with housing shortages or a very tight market, that’s asking a lot.
People need homes, and there is a balance to be struck for the public good.
Just as well I’m not arguing for rent control or any particular policy then isn’t it?
I’m pointing out that the “it’s my property I can do what I want” attitude needs to be balanced with public needs for housing, because society isn’t purely about optimising the content of your wallet, and extreme deregulation results in slums.
(Your linked paper there also says that rent control results in more properties having affordable rent at the low end of the market, but less overall rental property supply, indicating a reduction at the higher end. I’m good with that as a consequence, those who are better off can usually afford to get into purchasing a property. In some markets, like much of Australia, having fewer landlords and wannabe landlords competing to purchase properties would be a bonus. This actually looks like a win all round TBH.
tl;dr - congrats, you’ve used science to sell me on rent control)

They would. But second order effects ensure that this very act leads to the decline of housing prices. These effects being eliminated by rent control makes it the premier anti-tenant policy.
dataflow 5 hours ago [-]
What second-order effects...? Feels like such an oddly opqaue way to talk about them. And how do you ignore the effect of the fact that rent no longer rises during the life of the tenant, making it lower after a while than it would otherwise be...? (How) is it so obvious that that is dwarfed by the second-order effects of uncontrolled rent that it doesn't even warrant a mention? Because it isn't to me.
Aurornis 4 hours ago [-]
> And how do you ignore the effect of the fact that rent no longer rises during the life of the tenant,
Rent control schemes don’t work like this, except in completely broken policies.
Landlords are given an allowance for rent control increases year over year. The point is that they basically have to take the maximum allowed every year to avoid getting stuck.
Espressosaurus 4 hours ago [-]
If rent no longer rises then the profit doesn't rise commensurately with demand, so the money isn't there to build supply.
Rent control crushes supply to the degree that the rent control caps rents below the actual market rate.
If you're lucky enough to get rent controlled housing then you're in good shape. But good luck getting it when things get far enough down the timeline.
Rent fixing is the other side where supply is manipulated to extract the maximum profit. In this case the coordinated rent pricing action behaves like an oligopoly.
tyre 4 hours ago [-]
If rents can’t rise quickly, then the expected profit of a building goes down, which means prices for land go down, which means it is cheaper to build, which means it balances out.
If the balance is far enough off that everything turns into commercial real estate, that can be solved, too.

Prices are a signal, and price changes are how market participants can determine which way supply and demand curves are moving.
By legislating prices and price changes, the signal is muddied, and market participants cannot take action to match the movements of the supply and demand curves.
Prop 13’s property tax rate increase cap is also price fixing. These kinds of laws are mostly ways to enrich and reward those who got or were born somewhere first, and run counter to the vaunted meritocracy that a so called free market can encourage.
Edit: The most helpful thing the government can do is maximize price transparency, so the smaller entity can be on equal footing with the bigger entity about which way prices are moving. Tenant agreements should be public record, like land sales are, and that would not only help cops with kicking out squatters, but also give renters more power in negotiations.

These side effects of these dynamics are not going to be evident or resolved in the short term. It took decades for prop 13’s (and other effects) to compound and become visible, and it will take decades to undo.
There is no shortcut though, the incentives have to be set right, and there has to be patience for the results to show. Unfortunately, long term benefit at the expense of the short term is a core weakness in democracy.
rcpt 3 hours ago [-]
I don't think that's true. Prop 13 for example is priced into the market. Buyers bid higher because their taxes are frozen. This doesn't take decades to correct.
Market reactions are instant. Once the policy is fixed we don't have to wait for a generation
seanmcdirmid 3 hours ago [-]
Buyers bid higher because sellers are giving up their low property tax, not because the buyer will have a low property tax in a decade or two. Sellers are hesitant to sell because they are giving up a lot, California had to pass a special law just to let old people downsize without losing their low property tax on the big home they raised a family in.

With rent control, you are limited in how you can increase rent later, so it’s to your benefit to let the apartment sit vacant longer until you get a desirable rent. Without rent control, because you can just increase rent next year by whatever, you can rent it at the market rate right away without waiting.

You might prefer to have the vacancy filled faster rather than waiting for the highest possible price. These algorithmic pricing cases kind of revolve around this concept.
It is the value that the service provided the companies.
Landlord input a desired vacancy rate or time on Market, and service suggests the right price.

In San Francisco, I’m not a fan of Aaron Peskin’s ban on algorithmic rent-setting (Admin Code 37.10C https://codelibrary.amlegal.com/codes/san_francisco/latest/s...) (which is probably similar to the other cities) because 1) it goes beyond antitrust law in just banning data gathering for no good reason, and 2) it rewards bounty hunters.
1. It goes beyond antitrust guidelines by banning rent prediction using any “non-public competitor data”, which is stricter than the former antitrust guidelines which prohibited sharing “competitively sensitive variables” (https://www.ftc.gov/sites/default/files/attachments/dealings...). To the extent that it differs from banning competitively sensitive data, it is just banning the use of data to make rentals more efficient. If landlords are pricing accurately but not monopolistically, this should reduce turnover, reduce vacancy, and reduce the occasions where a listing gets a crowd of applicants, which is good for both landlord and tenant. It’s bad to try to ban accurate data.
2. It provides a private right of action for tenants and nonprofits to sue, just like Proposition 65 (Known by the State of California to cause cancer) incentivizes bounty hunters to sue. The point seems to be to punish landlords more than it is to establish fair rules.
And it seems that these lawsuits are just piggybacking on the DOJ settlement by punishing anyone who uses RealPage as soon as the ordinance becomes effective in 30 days while RealPage was already working to settle federally. The complaints (e.g. the SF one https://www.courtlistener.com/docket/73573242/gomez-v-greyst...) don’t have any new violations; just companies who are already settling. I don’t think that’s justice for a city to frontrun the federal settlement with new violations for the same program.

SF as a city has the fundamental problem that there's a huge part of the electorate will blame the housing shortage on absolutely anything they can find that's not the actual fundamental physical shortage of housing. That leads to an endless tangle of local laws and organizations supposedly trying to "do something about it", that are fundamentally just making the problem worse by adding marginal cost to every new already-difficult-to-pencil housing unit.

Can you elaborate on what is meant by “rent-fixing”?
A bunch of landlords all use the same software to tell them how to price rents. The software continually pushes prices higher and higher. The software requires landlords to use their pricing as a condition of use. Now you have a price-fixing cartel for rent.
Then they got sued by the company that was targeted, and immediately waffled and canceled the ban.
What's insane about all of this is that we also have Rent Control. There is no greater price fixing mechanism than Rent Control. Rent Control ensures that all landlords must seek the highest possible rent, because they are (potentially) tethered to it for life (of the tenant).
