Argentina passed a sweeping rent control law in 2020 and repealed it at the end of 2023. Rental listings in Buenos Aires jumped more than 170 percent and inflation-adjusted rents fell about 40 percent. New York is running the same experiment in slow motion, and Los Angeles is early in the same sequence.
I manage and sell rental property in Los Angeles County, so I read rent control research the way a mechanic reads recall notices. Most of it moves slowly enough that you can argue about it for a decade. Argentina did not. The country passed a sweeping rent control law in 2020, repealed it at the end of 2023, and produced a before and after clean enough to be worth your time.
What the 2020 law did
The Ley de Alquileres was sold as tenant protection. It set a three year minimum lease term, tied increases to a government index instead of the market, required contracts to be written in pesos, and turned removing a nonpaying tenant into a long legal process.
Argentina was running 50 to 100 percent annual inflation at the time. A three year peso lease with a government capped escalation, in that environment, is a written promise to lose money. Owners responded the way owners respond. They pulled units off the long term market, moved them to short term rentals, left them empty, or sold.
Prices did not behave the way the law intended. Cato Institute figures put the average new lease on a two bedroom in Buenos Aires at 18,000 pesos at the end of 2019 and 334,000 pesos by January 2024. Straight inflation over the same stretch would have landed near 210,000. The controlled market ran roughly 60 percent above the inflation path, not below it.
What happened after the repeal
Decree 70/2023 took effect at the end of December 2023 and gutted the rental law. Term, currency, and escalation clause went back to free negotiation between the parties. Listings came back fast.
The exact numbers depend on the window and the measure. The Daily Economy and Reason report Buenos Aires rental supply up more than 170 percent with real rents, adjusted for inflation, down about 40 percent from October 2023 levels. Other counts of the same period run higher on supply, above 200 percent, and more conservative on price, closer to a 27 percent real decline. Every serious measure points the same direction: more units listed, and rent rising slower than inflation.
Two caveats worth stating plainly. Argentina also stabilized a currency that was in freefall, so this is not a clean single variable experiment and anyone who presents it as one is selling something. And real rents falling is not the same as rents falling. A tenant signing today still writes a much bigger peso check than in 2019. The honest version of the claim is narrower than the headline version: removing the controls brought supply back and pulled rents down relative to inflation, in a market where the controls had visibly cut supply.
New York is running the same experiment in slow motion
The most recent New York City Housing and Vacancy Survey, conducted in 2023 and released in February 2024, put the citywide rental vacancy rate at 1.4 percent, the lowest since 1968. The survey runs roughly every three years, so that remains the current official figure. About one million apartments in the city are rent regulated.
In July 2026, state registration filings showed roughly 57,000 rent stabilized apartments sitting vacant, which is 5.6 percent of the regulated stock. That rate was 3.7 percent in 2016. Owners point to operating costs, the 2019 Housing Stability and Tenant Protection Act limits on recovering renovation spending, and the recent rent freeze. Tenant advocates dispute the explanation. Nobody disputes the count.
That is the part worth sitting with. A city with a 1.4 percent vacancy rate has 57,000 regulated apartments that nobody lives in. The City Council votes every three years to declare a continuing housing emergency, which is the legal trigger that keeps the stabilization system in place, and the shortage the emergency describes is partly produced by the system the declaration preserves.
Why this belongs on a Los Angeles landlord site
LA is not Buenos Aires and it is not New York. The mechanism is the same one, and we are earlier in the sequence.
In November 2025 the City Council rewrote the RSO formula: a 1 percent floor and a 4 percent ceiling replacing the old 3 to 8 percent range, allowable increases calculated at 90 percent of CPI, and the gas and electric allowances eliminated. Those changes land with the fiscal year that started July 1, 2026. In July 2025, substantial remodel stopped being a valid no fault ground under the Just Cause Ordinance, which covers single family homes, condos, ADUs, and everything built after October 1978. Under the Just Cause Ordinance's economic displacement provision, an increase above the lesser of 10 percent or CPI plus 5 percent lets the tenant leave and collect relocation, so even units outside the RSO caps have a practical ceiling.
Each of those on its own is survivable. Stacked, they do to the renovation math what New York's rules did to it. Rent is capped low, the cost of bringing a unit back to rentable condition is not capped at all, and the owner cannot recover the spend through the rent roll in any reasonable period. That is how you get 57,000 empty apartments in a city with a 1.4 percent vacancy rate. Nobody voted for that outcome. It is just what the arithmetic produces.
The operating question for owners here is not political. When your next unit turns over, does the renovation pencil, or do you re-rent it as is and defer the work again? Run that decision forward ten years across your building and you have New York's answer. Argentina's contribution is showing how quickly it reverses when the rules change.
