Rent control was sold to renters as protection. But is it really helping them?
Politicians use this topic in debates and leverage to appeal to the mass population. Cap what landlords can charge, and renters will be protected. It seems pretty straightforward, right?
Rents go up, tenants struggle, so the government steps in and limits increases. Problem solved.
Except it isn't. Decades of research across multiple countries have reached a consistent conclusion: rent control doesn't protect renters. It protects the specific renters who already have a rent-controlled unit, while making housing harder to find, more expensive, and lower quality for everyone else.
Who Rent Control Actually Protects
The core problem is who benefits. "Rent controls favor insiders —those already renting — at the expense of outsiders — people who need to find a new home," as economist Jorge Galindo of Esade in Madrid put it. Rent control delivers real benefits to a defined group of current tenants while imposing structural costs on everyone trying to enter the market.
Research from the Brookings Institution found that while rent control appears to help current tenants in the short run, in the long run it decreases affordability, fuels gentrification, and creates negative spillovers on the surrounding neighborhood. The people who benefit most tend to be those who have occupied controlled units longest. Low-income renters, younger workers, or growing families that housing policy is supposed to prioritize.
What Happens to Supply
The most consequential effect of rent control is what it does to the number of units available.
When landlords face below-market returns they can't recover through rent increases, they respond by either: they sell, convert, or let properties deteriorate rather than invest in them.
Rent control reduces profitability for housing providers, prompting some to neglect maintenance, or withdraw units from the market entirely.
The evidence is most striking from San Francisco, where a landmark Stanford University study examined the city's 1994 expansion of rent control to small multifamily buildings.
Researchers found that landlords reduced rental housing supply by 15%, selling to owner-occupants and redeveloping buildings. While rent control lowered displacement of incumbent renters in the short run, the lost rental supply drove up market rents in the long run. Market-rate rents citywide rose 5.1% as a direct result. The policy designed to keep housing affordable made it more expensive overall.
Argentina's Proof of Concept
Argentina's 2020 rent control law mandated minimum three-year leases and capped annual rent increases. While the law appeared to offer relief for tenants, it backfired badly. By late 2023, one in seven homes in Argentina sat empty while Buenos Aires residents struggled to find available rentals. Rents increased by an average of 140% in inflation-adjusted terms between 2020 and 2023.
When President Milei repealed the law in December 2023, the results were immediate. The supply of rental properties surged over 211%, and real prices fell 26.6% by mid-2024. Landlords who had been sitting on the sidelines returned almost instantly once they could price leases freely.
The lesson isn't that rent control is merely imperfect. It's that the housing affordability problem is fundamentally a supply problem. Restrict returns, supply contracts. Supply contracts, prices rise for everyone without a protected unit. Remove the restriction, supply returns.
What This Means for California
California has layered decades of rent control across its most supply-constrained markets. AB 1482 imposes statewide rent caps on most multifamily housing older than 15 years. Local ordinances in San Francisco, Los Angeles, and Oakland go further still and the political direction has consistently moved toward more regulation, not less.
For multifamily investors, this creates tension: operating costs rise while allowable rent increases are capped by statute. In markets where policy discourages new supply and degrades existing inventory, well-maintained, professionally managed properties become scarcer and more valuable over time.
The renters rent control was designed to protect deserve better than policies that shrink the available housing pool, reward incumbent tenants at the expense of new entrants, and reduce the incentive to build and maintain rental housing. The evidence supports a simple argument: Build more. Regulate less. Let supply do the work that price controls never have.
