A seller in Bel Air bought a home for $5 million a few years ago. Today it is worth $5.5 million. On paper, that is a $500,000 gain and reason to sell now. In practice, Measure ULA does not tax the gain. It taxes the sale price. The full $5.5 million crosses the City of Los Angeles transfer tax threshold, and the seller owes 4 percent of the entire figure, not 4 percent of the profit. That is $220,000 gone before commissions or closing costs are even discussed, on a property that only appreciated half a million dollars.
This is the detail that catches sellers off guard, and it is worth understanding before it catches you. But the deeper story is not the math on any single sale. It is where that math applies at all.
The tax follows a map, not a price bracket
Most people shopping or selling on the Westside think of it as one market: Brentwood, Bel Air, Pacific Palisades, Beverly Hills, Santa Monica, Malibu, all variations on the same luxury theme. Measure ULA does not see it that way. The tax applies only within the City of Los Angeles, and several of the neighborhoods that read as interchangeable on a map are, legally, entirely different jurisdictions.
Brentwood, Bel Air, Pacific Palisades and Hollywood Hills sit inside the City of Los Angeles. A qualifying sale in any of them owes the tax. Beverly Hills, West Hollywood, Santa Monica, Malibu and Manhattan Beach are separately incorporated cities. A sale in any of them does not.
| Inside City of Los Angeles (ULA applies) | Separately incorporated cities (ULA does not apply) |
|---|---|
| Brentwood | Beverly Hills |
| Bel Air | Santa Monica |
| Pacific Palisades | West Hollywood |
| Hollywood Hills | Malibu |
| Manhattan Beach |
Two estates a few miles apart, priced identically, marketed to the same buyer pool, can carry a six-figure difference in transaction cost purely because of which city clerk processes the deed. That is not a detail that shows up in a median price comparison. It only shows up once you are under contract.
What the number actually costs in 2026
For transactions closing after June 30, 2026, the active Measure ULA thresholds are $5.4 million and $10.9 million. Sales between those figures owe a 4 percent transfer tax. Sales at $10.9 million or above owe 5.5 percent, on top of the existing city and county transfer taxes that apply to every sale regardless of size. The tax has now generated close to $1.2 billion since it took effect on April 1, 2023, drawn from 1,633 qualifying transactions as of the end of April 2026, according to figures the city's Housing Department has reported.
That volume of revenue is also a volume of evidence about behavior. Because the tax is not marginal, meaning it applies to the entire sale price rather than only the portion above the line, it creates a real disincentive to price a home just over a threshold rather than just under it. A property that might otherwise list at $5.5 million can make more financial sense to position at $5.35 million, even if the underlying value argument supports more. Sellers and their agents now have to weigh that cliff against whatever additional price a longer marketing window might produce, a calculation that simply did not exist before April 2023.
The behavior it has changed
UCLA research has found that the tax reduced the odds of a Los Angeles property selling above $5 million by as much as 55 percent compared to the pre-ULA period. That is not a small nudge in pricing strategy. It is a structural shift in whether certain sales happen at all inside city limits.
Brokers who work these transactions describe the same shift in their own words. Emil Hartoonian of The Agency has said the tax "has become part of nearly every meaningful conversation we have about timing, pricing, renovation and whether a sale makes financial sense." He has also noted it cuts both ways: some owners delay selling to avoid the tax, while others conclude that tying up money and years in a renovation carries more risk than selling today.
That tension is reshaping entire businesses, not just individual listings. Oren Levy, founder of the luxury homebuilder Gesh Group, has said his company's project mix flipped after ULA took effect. Before the tax, Gesh Group's work was roughly 80 percent new development and 20 percent remodels. Now it runs closer to 60 percent remodeling and 40 percent new construction, as owners inside the city choose to improve what they own rather than sell it and absorb the tax on the way out.
None of this means the market inside city limits has stalled. Deals in the affected zip codes still close at full asking price when they are positioned correctly. But every one of those sales now carries a line item that a nearly identical property in Beverly Hills or Santa Monica simply does not.
Pacific Palisades is the live test case right now
No neighborhood makes the boundary line more consequential than Pacific Palisades, and the reason is timing rather than geography. Because the Palisades sits inside the City of Los Angeles, homeowners who lost properties in the January 2025 fire have been selling damaged and destroyed lots subject to the same 4 to 5.5 percent tax as any other qualifying sale in the city, even when the sale is closer to a forced necessity than a discretionary decision.
That fact has become a live policy fight this year. On a 13-1 vote, the Los Angeles City Council placed a measure on the November 2026 ballot asking voters to grant Palisades fire victims a one-time, five-year exemption from Measure ULA, running from the date of the fire through early 2030. Councilmember Traci Park, who represents the Palisades, authored the proposal after hearing from what she has described as hundreds of homeowners whose recovery plans were complicated by the tax.
"In those instances, where a sale is by no means voluntary, I don't think we should impede that objective."
Mayor Karen Bass backed the underlying framework in a letter to the Council before the vote. Councilmember Eunisses Hernandez was the lone dissent. The Housing Department has estimated the exemption could reduce Measure ULA's annual revenue by roughly 6 percent, or about $32 million, if voters approve it.
Whatever the outcome in November, the fact that this question is being decided at the ballot box tells you something the median price data cannot: the boundary that defines who owes this tax is not a fixed feature of the Westside. It is being actively renegotiated, neighborhood by neighborhood, in real time.
What this means if you are comparing neighborhoods
A statewide effort backed by the Howard Jarvis Taxpayers Association came close to putting Measure ULA's survival to a broader vote before it was withdrawn this year in exchange for a legislative deal in Sacramento, where Assemblymember Buffy Wicks has introduced separate legislation that would cap transfer taxes statewide at 1.5 percent. Nothing about this policy is settled, which is exactly why it belongs in any serious comparison between Westside neighborhoods rather than in a footnote.
If you are weighing a property in Brentwood against one in Beverly Hills, or a Pacific Palisades rebuild against a comparable lot in Malibu, the sale price is only part of the comparison. The jurisdiction the property sits in determines whether an additional 4 to 5.5 percent applies at closing, and that single fact can outweigh a meaningful difference in list price once you run the actual net proceeds. It also affects timing: a seller near a threshold inside city limits has real reasons to consider an off-market process that gives more control over final price relative to the cliff, a strategy brokers report seeing more often as owners try to manage exposure to the tax.
None of this is legal or tax advice, and the ballot measure affecting the Palisades has not yet been decided by voters. But knowing which side of the city line a property sits on, and what that means for the number at closing, is the kind of detail that should shape a pricing conversation well before a listing goes live.
A few questions worth asking before you list or write an offer
Does Measure ULA apply to a home in unincorporated Los Angeles County? No. The tax is specific to the City of Los Angeles. Unincorporated county land and separately incorporated cities such as Beverly Hills, Santa Monica, West Hollywood and Malibu fall outside its reach.
Is the tax based on profit or on the full sale price? The full sale price. Measure ULA is a transfer tax assessed on the gross transaction value, not a capital gains tax on the difference between purchase and sale price.
Will the Pacific Palisades exemption apply automatically if fire victims sell before November? No. The exemption requires voter approval on the November 2026 ballot before it takes effect, and it would apply retroactively to the date of the fire only once passed.
Every one of these decisions, whether it is a threshold, a jurisdiction line, or a ballot measure still working its way to voters, changes what a Westside sale actually nets. That is the kind of detail worth confirming property by property rather than assuming from a neighborhood's reputation. Gary Glass Estates works these specific boundaries across Brentwood, Bel Air, Pacific Palisades, Beverly Hills, Santa Monica and Malibu every day. If you are weighing a sale near one of these thresholds, request a private showing to talk through what the number actually looks like for your property.
