California’s LA Mansion Tax Has Raised Over $1 Billion — But Research Shows It May Be Making the Housing Crisis Worse
Why It Matters
California’s housing affordability crisis remains one of the most severe in the nation, and Los Angeles has been ground zero for the debate over how to fund solutions. A tax approved by Los Angeles voters in 2022 — marketed as a tool to generate affordable housing funding by taxing high-end real estate sales — has instead shown signs of worsening the very problem it was designed to solve, according to researchers.
With the debate now expected to move beyond Los Angeles to a statewide discussion, the consequences of the so-called “mansion tax” carry significant implications for California’s housing market and taxpayers across the state.
What Happened
Los Angeles voters approved the mansion tax in 2022. The measure imposes a 4% tax on the sale of any property exceeding $5 million and a 5.5% tax on properties selling for more than $10 million. Proceeds were designated to fund affordable housing construction as well as rental and eviction assistance programs for low-income residents.
Proponents argued the tax was a fair mechanism to capture wealth from high-end homeowners — many of whom have benefited from Proposition 13 property assessment restrictions and decades of rising property values fueled by public infrastructure investments. Under the tax’s logic, sellers of luxury properties would return a portion of those gains to the broader community at the moment of sale, when they are most cash-liquid.
Similar versions of the tax have been adopted in other jurisdictions, including San Francisco. The Los Angeles measure has raised more than $1.14 billion since it was adopted.
However, researchers say the tax has not delivered on its central promise. Rather than spurring a wave of new affordable housing construction, the measure appears to have suppressed development of the multi-family residential units — apartment buildings — that economists broadly agree are the most effective mechanism for easing rental prices.
By the Numbers
$1.14 billion — Total revenue raised by the Los Angeles mansion tax since its adoption in 2022.
4% — Tax rate applied to property sales exceeding $5 million.
5.5% — Tax rate applied to property sales exceeding $10 million.
1,540 — Permits issued for multifamily construction projects in Los Angeles in 2022, the year the tax was approved.
Under 1,000 — Multifamily construction permits issued in Los Angeles in 2024, representing a significant decline from pre-tax levels.
What Researchers Found
A study by Yingru Pan of UCLA found that the mansion tax has produced outcomes contrary to its stated goals. Pan concluded that “policies targeting luxury markets risk collateral damage to the very segments they aim to uplift,” and warned that the tax “may deepen disparities by discouraging moderate-density solutions.”
The research underscores a concern often raised by free-market housing economists: that taxes and regulations targeting high-end real estate transactions can ripple through the broader market, discouraging investment and construction at all price levels. In Los Angeles, the decline in multifamily construction permits between 2022 and 2024 aligns with that theory.
Researchers characterized the results as “unambiguous” — the tax has depressed construction of apartment buildings, precisely the segment of the market most capable of reducing rents citywide through increased supply.
Zoom Out
Los Angeles is not alone in experimenting with transfer taxes on high-value real estate as a housing funding mechanism. San Francisco has adopted similar measures, and the broader policy model has attracted attention from progressive-leaning municipalities seeking to tax wealth at the point of property sale rather than through direct income or property taxes.
The California housing crisis has been driven by years of government-imposed restrictions on construction, including zoning rules, environmental regulations, and permitting bottlenecks that have kept housing supply far below demand. Critics of the mansion tax argue that adding additional transaction costs compounds existing disincentives to build. As economic uncertainty continues to ripple through California’s major cities, the cost of misguided government interventions is increasingly difficult to ignore.
Federal economic policy has also introduced additional uncertainty into the construction market, with materials costs and supply chains already under pressure.
What’s Next
City officials in Los Angeles have indicated they do not plan to adjust the mansion tax in the near term. However, the policy debate is expected to expand to the state level, where California lawmakers may examine whether similar transfer tax structures should be adopted — or avoided — statewide.
The outcome of that debate could shape housing development policy across California for years to come. Political attention in California is already fractured amid a turbulent environment in Sacramento, but housing advocates on both sides of the issue are pushing for action as permit numbers continue to decline.
