The Mansion Tax Line Already Moved in Sherman Oaks. Most Sellers Haven't Noticed.

The median home in Sherman Oaks sold for around $1.5 million in the three months ending June 2026, according to Redfin's tracked closings. That number sits nowhere near the Los Angeles mansion tax. And yet Sherman Oaks shows up by name in the city's own transfer tax data, generating $13.4 million from multifamily and mixed use sales alone since Measure ULA took effect, enough to rank it among the handful of neighborhoods the city's Housing Department calls out as a standout contributor.

That gap is the story. Most of Sherman Oaks trades in a price band the tax never touches. But a real and active slice of the neighborhood, the hillside estates south of Ventura Boulevard and the new construction on the upslope lots, sits close enough to the threshold that the tax has started changing how owners behave. Some are pricing around it. Some, according to industry reporting this year, are choosing not to sell at all.

A Threshold That Moved Without a Headline

Measure ULA adds a transfer tax on top of the standard city and county documentary transfer taxes whenever a property sells above a set price inside the City of Los Angeles. Sherman Oaks sits fully within city limits, so it is fully exposed. Neighboring cities like Beverly Hills, Calabasas, and West Hollywood are not, because they govern their own transfer tax rules independently.

The part that catches people off guard is that the threshold is not fixed. The Los Angeles Office of Finance adjusts it every July 1 based on the Chained Consumer Price Index. Through June 30, 2026, the bands were $5,300,000 and $10,600,000. As of September 2026, the current bands are $5,400,000 and $10,900,000, confirmed directly on the city's own Measure ULA page. The rates themselves have not changed, 4 percent on the lower tier and 5.5 percent on the upper one, but the dollar line where those rates start now sits $100,000 to $300,000 higher than it did a year ago.

That matters for anyone who has been telling themselves they need to sell before the tax gets worse. The increase already happened. It happened in July, two months before this was written, and it will not move again until next July. A Sherman Oaks Hills owner sitting on a property that might list in the mid $5 millions has more room under the current thresholds than they had a year ago, not less.

Why the Tax Bites Harder Than It Sounds

Measure ULA is not structured like an income tax bracket. There is no marginal calculation where only the dollars above the line get taxed. The entire sale price is taxed once it crosses the threshold. A property that sells for $5,399,999 owes nothing under ULA. A property that sells for $5,400,001 owes 4 percent of the full amount, not just the two dollars over the line.

Here is what that looks like in practice at prices that show up in the Sherman Oaks Hills right now.

A single-family listing at 15321 Kingswood Lane in Sherman Oaks, a seven-bedroom, 8,200 square foot property, was recently priced at $10,495,000, comfortably under the $10,900,000 line where the higher rate kicks in. That is not a coincidence agents ignore. Pricing decisions on hillside estates increasingly get built around where the next tier starts, because a few hundred thousand dollars in list price can trigger a tax bill that erases the difference and then some.

The tax is calculated on what the deed says the property sold for, not on what the seller cleared after the mortgage, the renovation costs, or the years of ownership. That distinction surprises more sellers than the rate itself.

Renovating Instead of Listing

The more interesting shift is not in how sellers price near the line. It is in how many of them are choosing not to cross it at all.

Emil Hartoonian, an agent with The Agency who works Sherman Oaks and Studio City, told The Real Deal this year that Measure ULA has become part of nearly every meaningful conversation he has with clients about timing, pricing, and whether a sale makes financial sense in the first place. Buyers, he pointed out, generally do not pay a premium just because the seller is absorbing a transfer tax. The cost lands entirely on one side of the table.

Oren Levy, founder of the luxury homebuilding and remodeling firm Gesh Group, described a concrete shift in his own project mix to The Real Deal: before Measure ULA, roughly 80 percent of his firm's work was new development and 20 percent was remodeling. That ratio has flipped toward roughly 60 percent remodel work, with much of it concentrated in Sherman Oaks, Encino, Bel Air, and Brentwood. Levy pointed to one Brentwood case where a homeowner planning to sell calculated that the tax plus standard commission would have consumed about 11 percent of the sale proceeds. They reinvested in the existing house instead.

Hartoonian is careful to note that renovation is not automatically the safer move. There is no guarantee a remodel returns its full cost at resale, and living through construction has its own disruption. But the math that used to point straightforwardly toward selling now has a real competing option on the table for owners near the threshold, and that is a genuine behavioral change in how Sherman Oaks Hills inventory moves.

The Bigger Picture Behind the Number

Citywide, Measure ULA has generated more than $1 billion since it took effect in April 2023, with commercial transactions contributing a larger share of total revenue than single-family homes. Researchers who have studied the policy found that the odds of a Los Angeles property selling above $5 million dropped by roughly 55 percent since the tax began, a chilling effect that shows up in fewer high-end transactions rather than lower prices.

There was a real possibility earlier this year that the rules could change. A proposal from Councilmember Nithya Raman would have carved out a 15-year exemption for new construction and offered relief for Palisades fire victims, but the City Council declined in January 2026 to fast-track that rewrite onto a near-term ballot. Separately, a campaign backed by the Howard Jarvis Taxpayers Association was gathering signatures for a statewide measure that could cap local transfer taxes like Measure ULA, working against a signature deadline in late February 2026. Neither effort has changed the numbers currently published by the city's Office of Finance.

The practical upshot for a Sherman Oaks seller: the rules in front of you right now are the rules you should plan around. The next scheduled change to the thresholds is the routine inflation adjustment next July.

What This Means If You Own in the Sherman Oaks Hills

If your property could reasonably list anywhere from $5 million to $11 million, the conversation before you set a price should include a specific run of the numbers at your likely sale price and just above it. A same day comparative analysis can show you exactly how close you sit to either tier and whether a small pricing adjustment changes your net by six figures.

Off-market strategies do not remove the obligation. If the price crosses the threshold, the tax applies whether the sale happened through open marketing or a quiet, invitation-only process. Timing your closing relative to July 1 no longer helps this year, since the higher thresholds are already in effect and will not shift again until next summer.

And if you are weighing a remodel against a sale, get real numbers on both sides before you decide. What a renovation actually returns at resale in your specific pocket of Sherman Oaks, whether that is the flats near Kester or the view lots above Dickens Street, is a different question than what it costs to build.

Quick Answers for Sherman Oaks Sellers Near the Threshold

Does Measure ULA apply everywhere in Sherman Oaks? Yes. Sherman Oaks sits entirely within the City of Los Angeles, so any sale above the current thresholds is subject to the tax regardless of which side of Ventura Boulevard the property sits on.

Is the tax based on profit or on the sale price? The full sale price. Measure ULA is a transfer tax, not a capital gains tax, so the original purchase price, mortgage balance, and improvement costs do not reduce what is owed.

Can a 1031 exchange defer this tax? No. A 1031 exchange defers capital gains tax. Measure ULA is a separate transfer tax collected at closing regardless of whether the seller reinvests the proceeds.

Who actually pays it at closing? By local custom, the seller pays, though the allocation is technically negotiable in the purchase contract. In practice, buyers in this price range rarely agree to absorb it.
