What the ULA “Mansion Tax” Has Actually Done to LA’s Luxury Market 

In November 2022, Los Angeles voters approved Measure ULA — the United to House LA initiative, marketed to the public as a “mansion tax on millionaires and billionaires.” The promise was sweeping: generate up to $1.1 billion annually to fund affordable housing and homeless services by levying a 4% tax on property sales above $5 million and a 5.5% tax on sales above $10 million. It sounded clean, targeted, and overdue.

More than three years after Measure ULA took effect on April 1, 2023, the data is in. And it tells a story far more complicated — and contested — than either its supporters or critics initially expected.

What the Tax Actually Does (And Who It Hits)

First, the mechanics. Measure ULA is a transfer tax, not a property tax. It applies at the moment of sale to any property sold within the City of Los Angeles — not unincorporated LA County, not Beverly Hills, not Culver City — for more than $5.15 million (the threshold adjusts for inflation). The tax is paid by the seller on top of existing city and county transfer taxes.

The “mansion” framing implied the primary targets would be luxury single-family homes in the hills and along the Westside. The reality is that the tax falls on any property sale above the threshold: apartment buildings, commercial properties, developable land, mixed-use projects. A 16-unit apartment building in Silver Lake, a warehouse in Boyle Heights, a retail strip in Hollywood — all subject to ULA if the sale price crosses the line.

The Numbers: Revenue, Sales, and Market Behavior

The headline figures tell a split story.

On revenue: as of May 2026, Measure ULA has raised approximately $1.2 billion over three years. That sounds like a win — until you consider that city projections promised $600 million to $1.1 billion every single year. In its first year alone, ULA generated only about $215 million, roughly a quarter of the minimum projected annual revenue. The shortfall has modestly improved since then, but the gap between promise and reality has never closed.

On market activity: a UCLA Lewis Center study found that high-end real estate sales in Los Angeles fell by more than 50% after Measure ULA took effect. A separate analysis by UCLA researchers found that since the tax kicked in, the odds of a transaction exceeding the threshold dropped by 50%, and transactions involving commercial, industrial, and multifamily properties fell by 30–50%. On the residential side, MLS data shows sale sides above $5 million plunged nearly 40% following ULA’s implementation.

The market didn’t just slow down — it rewired itself around the tax.

How Sellers and Investors Responded

Experienced sellers and institutional investors move fast when a new cost structure enters the market. Several behavioral shifts emerged almost immediately after April 2023:

Pricing compression below the threshold. Properties that might have listed at $5.3M or $5.5M were repriced to come in just under $5.15M to avoid triggering the tax entirely. This distorted valuations at the margin.

• Holding and remodeling rather than selling. A UCLA Anderson study found that luxury homeowners increasingly opted to renovate in place rather than pay the transfer tax, further tightening already constrained resale supply.
• Deal structure workarounds. Some sellers and advisors explored restructuring ownership through LLCs, partnerships, or intrafamily transfers to avoid triggering a direct sale — though these approaches carry their own legal and tax risks.
• Developer pullback. Apartment and mixed-use developers, for whom the exit sale is the mechanism of return, began routing projects to neighboring jurisdictions not subject to ULA — Santa Monica, Culver City, Burbank — where the same tax doesn’t apply.

The Unintended Consequences

The sharpest critique of Measure ULA isn’t the revenue shortfall — it’s that the tax appears to be suppressing the very type of activity that creates housing.

Researchers from Harvard Business School, UC San Diego, and UC Irvine published a 2025 study with a striking finding: for every dollar raised by ULA, the region could lose up to $1.38 in future property tax revenue. The mechanism is straightforward — fewer transactions mean fewer reassessments at current market values, which constrains the tax base for schools, transit, and county services.

A UCLA Anderson analysis found that ULA’s primary effect was to broadly suppress construction activity, not shift it toward affordability. The “mid-tier” apartment buildings and developable sites most affected by the tax are exactly the projects responsible for most of LA’s housing production. When those deals stop penciling, the pipeline slows — and a slower pipeline eventually shows up as higher rents for everyone.

There is also the fairness issue that rarely gets discussed in the political back-and-forth. A seller who bought a home for $5.25 million in 2020 and sells for $5.75 million in 2025 — a modest gain that barely keeps pace with inflation — still owes 4% on the full sale price. Combined with broker commissions, that seller could easily be walking away at a loss. The tax has no exemption for sellers who are not actually “millionaires and billionaires” in the way the ballot campaign described.

What the Money Is Actually Funding

In fairness to ULA, the revenue it has generated is doing real work. City data and independent reporting show the funds have been used for:

•  Rental assistance programs to keep residents in their homes during hardship
• An accelerator fund that restarted nine previously stalled affordable housing projects, including a 303-unit building downtown and a 48-unit complex in Lincoln Heights
• Financing support for affordable developments in East Hollywood, Boyle Heights, and other underserved neighborhoods

The city recorded its first drop in homeless count in years in 2024. ULA supporters credit the measure’s rental assistance programs as a contributing factor. That’s not nothing.

Where Things Stand in 2026

In January 2026, the Los Angeles City Council voted to keep Measure ULA intact, effectively removing it from the 2026 ballot and blocking any near-term repeal or reform effort. At the same time, a proposed statewide measure that would cap municipal transfer taxes statewide is moving through Sacramento, potentially forcing the broader policy debate to the state level.

Supporters argue that building permits citywide increased by 60% between fall 2024 and fall 2025, and that ULA’s impact on housing construction is overstated by critics. Opponents point to the persistent revenue gap, the flight of multifamily investment to neighboring cities, and the growing body of academic research suggesting the costs outweigh the benefits.

The honest answer is that both things are true. ULA is doing some of what it promised. It is also creating market distortions that its architects did not fully anticipate — and that are falling disproportionately on the multifamily and commercial segments, not just on luxury single-family sellers.

What This Means If You’re Buying or Selling in LA

If you own or are considering a property in the City of Los Angeles above the $5 million threshold, Measure ULA is a real cost that should be modeled into any sale scenario. A $6 million sale generates $240,000 in ULA tax alone. A $12 million sale generates $660,000. These are not incidental line items.

Buyers negotiating in this price range should understand that the seller’s tax burden is likely being factored into their pricing expectations. In a market where luxury volume has contracted significantly, both sides have less comp support than they did in 2021 or 2022 — which means pricing conversations in this segment require more context, not less.

For investors and developers evaluating sites within the city limits, the calculus has shifted. Projects that might have worked at a $6 or $7 million exit several years ago need to be re-underwritten with ULA baked in. That’s pushing capital toward adjacent jurisdictions or toward smaller projects that stay below the threshold.

The “mansion tax” turned out to be much broader than its branding. Three years in, its effects are still being debated — but its presence in the market is not.
