Los Angeles’ mansion tax has collected $1.14 billion since voters approved it in 2022. The numbers look like a win. They aren’t.
The levy charges 4% on property sales above $5 million and 5.5% on transactions above $10 million. Voters backed it under a straightforward pitch: owners who’d accumulated decades of gains, many of them shielded from reassessment by Proposition 13, would share a slice of that wealth when they sold. The money would fund affordable housing and keep low-income Angelenos from losing their homes.
That’s not what happened.
Multifamily construction permits in Los Angeles fell from 1,540 in 2022 to under 1,000 in 2024, according to city data. Apartment buildings are the segment of the market most capable of pulling rents down across the broader housing stock, and that’s precisely the segment that cratered. The drop didn’t distribute evenly across the region.
UCLA researcher Yingru Pan tracked the tax’s effects and found that new construction permits in Los Angeles dropped 21% after the levy took hold. Santa Monica, Burbank, and Culver City all faced the same macro headwinds during the same period, including rising construction costs and shifting federal trade policies, yet permit activity in those cities held comparatively steady. The gap between Los Angeles and its neighbors is difficult to explain by regional economics alone.
Pan’s conclusions weren’t gentle. “Policies targeting luxury markets risk collateral damage to the very segments they aim to uplift,” Pan said, and the research found the tax “may deepen disparities by discouraging moderate-density solutions.” That’s a serious charge against a measure voters were told would fix the affordability crisis, not worsen it.
The mechanism isn’t mysterious once you understand how developers actually work. Mid-range multifamily projects, not glass towers but the workhorse apartment buildings that add genuine rental supply, typically get sold by developers when construction wraps up. In Los Angeles, a completed apartment building almost certainly clears the $5 million threshold. The 4% tax then lands on a transaction that’s already running thin margins. Some developers decide the numbers don’t pencil. Others take their projects to Burbank or Culver City, where the same building doesn’t carry the same exit cost.
San Francisco runs a comparable transfer tax structure, and supporters of that model argue the revenue more than justifies whatever drag it creates. Los Angeles backers make a version of the same argument, and it’s true that $1.14 billion is real money. The city has directed those funds toward rental and eviction assistance programs and some housing construction. If you’re an Angeleno who kept your apartment because of that assistance, the tax did something tangible for you.
But you can’t spend $1.14 billion on affordable housing programs and simultaneously accept that the policy is suppressing the apartment construction that would lower rents in the first place. The math doesn’t hold. Several cities across the country have watched transfer taxes produce exactly this tradeoff, generating revenue on one side while chilling supply on the other, and Los Angeles is 13 million people deep into finding out if that pattern holds here too.
The Trump administration’s trade policy chaos has hurt construction across every major market. That’s a real factor, and it’s contributed to slowdowns well beyond Los Angeles. But Pan’s regional comparison strips that excuse out of the analysis. Every city in the Los Angeles metro absorbed the same federal uncertainty. None of them saw permit numbers fall the way Los Angeles did after 2022.
Raising $1.14 billion was never going to be painless. The question voters didn’t get asked clearly enough is what the full cost would be, and Pan’s research is now providing answers that the original campaign literature didn’t offer. Los Angeles in 2026 has a funded assistance program and a weakened construction pipeline, and those two outcomes are connected in ways that complicate any straightforward defense of the tax.
The city hasn’t announced plans to revisit the levy’s structure.
