A seller closing on a $6 million condo at Sierra Towers keeps roughly $267,000 more than a seller closing on the identical price two blocks south, on the Los Angeles side of the same street. Same buyer pool, same escrow timeline, same square footage. The difference comes down to which city stamps the deed.
That gap is not a rounding error or a quirk of one closing statement. It is the predictable result of two separate tax regimes sitting on either side of an incorporated city line that runs through the middle of West Hollywood's luxury condo corridor. For sellers of high-value product in this market, and for the agents structuring those sales, the line matters more at closing than it ever does at move-in.
What Measure ULA actually taxes
Measure ULA, the tax voters approved in November 2022 and nicknamed the mansion tax, applies only inside the City of Los Angeles. It is a transfer tax, not a capital gains tax, and it is calculated on the full gross sale price the moment it crosses a threshold, not on the amount above that threshold. A $10.85 million sale sits in the lower tier. A $10.95 million sale pays the higher rate on the entire price.
Those thresholds reset every July based on the Chained Consumer Price Index. As of July 1, 2026, the active rates are 4 percent on sales at or above $5.4 million and 5.5 percent on sales at or above $10.9 million, according to the Los Angeles Office of Finance. The tax stacks on top of the city's existing base transfer tax of 0.45 percent and the Los Angeles County documentary transfer tax of 0.11 percent, which applies countywide regardless of which city you're in.
West Hollywood, Beverly Hills, Santa Monica, and Culver City are all separately incorporated cities. None of them fall under Measure ULA. West Hollywood goes a step further: the city has confirmed on its own finance pages that it carries no additional property transfer tax at all, meaning a West Hollywood closing pays only the county's 0.11 percent and nothing else.
The math at the price points WeHo actually sells
Run the numbers at two price points that reflect what actually trades in this market and the gap stops being abstract.
| Sale price | Los Angeles side (county + city base + ULA) | West Hollywood side (county only) | Difference |
|---|---|---|---|
| $6,000,000 | $6,600 + $27,000 + $240,000 = $273,600 | $6,600 | $267,000 |
| $11,000,000 | $12,100 + $49,500 + $605,000 = $666,600 | $12,100 | $654,500 |
These figures follow the published rates directly and round to the nearest $500 for the base tax as county rules require, so an individual escrow statement may land a few hundred dollars off either way. The pattern holds regardless: at $6 million, the LA-side seller pays roughly forty times what the West Hollywood seller pays. At $11 million, the multiplier climbs past fifty.
Where the line actually runs
This isn't a hypothetical drawn on a map. The Sunset Strip corridor between Crescent Heights and Doheny, where Sierra Towers has housed high-profile residents for decades, sits inside West Hollywood city limits. The West Hollywood EDITION, the hotel-branded condominium tower on Sunset, and The Ainsley in the Melrose District are marketed and sold explicitly as West Hollywood addresses, which means all three transact under the county-only tax structure.
Cross into Beverly Grove, the pocket wedged between West Hollywood's northern edge, the Beverly Hills city line to the west, Fairfax Avenue to the east, and Wilshire and San Vicente to the south, and you're back inside the City of Los Angeles. Every condo and single-family sale there is legally exposed to Measure ULA the moment it crosses $5.4 million.
The boundary isn't cosmetic. It determines which finance department collects the check.
The part that keeps most of Beverly Grove out of the story
Here's where the picture gets more interesting than a simple map exercise. Beverly Grove condos carry a median list price around $1.29 million and single-family homes start near $1.3 million, climbing toward $2 million or more on blocks closest to the Beverly Hills line, as of August 2026 listing data. That means the overwhelming majority of Beverly Grove transactions never approach the $5.4 million ULA threshold in the first place. The tax is real and the exposure is real, but for most of the neighborhood's actual sales, it never triggers.
The exposure concentrates almost entirely in the higher end of the market, which is precisely the segment where West Hollywood's condo towers compete. A $1.5 million Beverly Grove bungalow and a $6 million West Hollywood high-rise unit aren't really in the same conversation. But a $6 million penthouse a few blocks apart on either side of the city line very much are, and only one of those two sellers writes a $240,000 check to the city.
What this means for pricing and timing a sale near the line
For a listing anywhere near the West Hollywood border, confirming jurisdiction isn't a formality, it's a pricing input. Two properties that look identical on paper, similar square footage, similar finish level, similar building amenities, can produce net proceeds that differ by six figures purely because one deed records in West Hollywood and the other in the City of Los Angeles. Escrow and title should confirm the exact jurisdiction early, since block-to-block boundaries in this part of the Westside don't always match casual assumptions about which side of a street belongs to which city.
Timing carries its own wrinkle. A statewide ballot initiative backed by the Howard Jarvis Taxpayers Association is targeting the November 2026 ballot with the goal of repealing or significantly limiting Measure ULA, according to legal analysis published this year. Nothing has changed yet. The tax remains in full effect on the City of Los Angeles side as of today, and any statewide result from that ballot wouldn't reshape closings that happen before the vote, let alone before any resulting law takes effect. Sellers weighing a sale on the LA side of the line should plan around current rules, not a possible future repeal.
One other assumption worth correcting: a 1031 exchange does not defer or reduce Measure ULA. Because the tax attaches to the transfer of the deed rather than to capital gains, like-kind exchange treatment has no bearing on it. Sellers who plan to roll proceeds into a new property still owe the full ULA amount at closing if the sale price crosses the threshold.
Frequently Asked Questions
Does Measure ULA apply if my building sits right on the West Hollywood and Los Angeles border? Jurisdiction is determined by the recorded city limits, not by which side of a street feels more like West Hollywood. Escrow and title can confirm the exact boundary for a specific parcel before you set a list price.
Can a 1031 exchange help me avoid the tax on the Los Angeles side? No. Measure ULA is a documentary transfer tax assessed at the time of transfer, separate from capital gains treatment, so a 1031 exchange doesn't reduce or defer it.
Will the November 2026 ballot initiative change any of this before I sell? Not yet. The initiative targets a future statewide vote and any change would take effect after that vote and any subsequent implementation period. Current thresholds and rates apply to any closing between now and then.
