L.A.'s Mansion Tax Was Meant to Fund Housing. Research Says It May Be Backfiring.

New research indicates that Los Angeles's landmark "Mansion Tax" may be undermining its own goal of funding affordable housing. The study suggests the policy is canceling out a significant portion of the revenue it was designed to generate.

Measure ULA, approved by voters in late 2022, imposes a tiered levy on high-value property transactions: 4% on sales between $5 million and $10 million, and 5.5% on sales exceeding $10 million. The initiative was championed as a way to raise hundreds of millions annually to combat the city's severe homelessness crisis through new housing construction and tenant protections.

However, economic analysis reveals a sharp decline in the volume of high-end real estate sales subject to the tax since its enactment. This market slowdown appears to be so pronounced that the resulting drop in overall transaction tax revenue—from standard city transfer taxes—may largely offset the new funds collected specifically under Measure ULA. In essence, while the measure brings in dedicated revenue, it may simultaneously depress other, pre-existing streams of city income from the same market sector.

Proponents argue that long-term revenue will stabilize and that the funds are already being allocated to vital projects. Critics, including the new research, contend the policy acts as a deterrent, discouraging sales and potentially lowering property values in the luxury market, thereby reducing the overall tax base. The debate highlights the complex challenges of using targeted tax policy to address systemic urban issues, as city officials now grapple with whether the measure's benefits will ultimately outweigh its apparent initial fiscal drawbacks.
