Tech Billionaires and Realtors Bankroll California Ballot Measure Targeting LA Transfer Tax

At least $14.4 million in documented contributions from Google co-founder Sergey Brin, venture capitalist John Doerr, and the California Association of Realtors are funding a November 2026 ballot...

The single most documented fact in the California Fair Political Practices Commission's Top 10 Contributor list for the November 2026 general election is this: an intermediary committee called 'Building a Better California,' whose listed top donors are Google co-founder Sergey Brin and Kleiner Perkins Chairman L. John Doerr III, contributed $6,000,000 to support a statewide ballot measure that would prohibit charter cities from imposing real estate transfer taxes. Los Angeles is a charter city. The tax it currently imposes — Measure ULA, passed by city voters in 2022 — charges 4% on property sales above $5 million and 5.5% on sales above $10 million. The math of the financial incentive is not complicated.

The ballot measure formally titled the California Two-Thirds Vote Requirement for Special Taxes and Charter City Real Estate Transfer Tax Prohibition Initiative operates through two registered supporting committees: 'Protect Prop. 13' and 'Californians to Restore Local Taxpayers' Right to Vote on Taxes.' Combined, they have reported over $14.4 million in contributions, according to FPPC filings. The measure's practical effect, as described on Ballotpedia, would be to require two-thirds supermajority voter approval for special taxes and to flatly prohibit charter cities from imposing real estate transfer taxes — a provision that directly threatens Los Angeles's existing ULA levy.

The second-largest documented source of funding is the California Association of Realtors, which has deployed $5,000,000 through a two-tier structure. Its Issues Mobilization PAC contributed $1,000,000 directly while simultaneously serving as the top donor to a campaign-specific committee called 'Homeownership for Families, sponsored by California Association of Realtors,' which contributed an additional $4,000,000, per FPPC Top 10 filings. CAR represents approximately 200,000 real estate licensees in California and has historically opposed measures that increase transaction costs or suppress sales volume. Real estate transfer taxes do both. The organization's financial stake in eliminating such taxes is institutional, not incidental.

The third major funding bloc is the building trades, specifically the Carpenters union at three levels of its organizational structure. The United Brotherhood of Carpenters and Joiners of America contributed $800,000 from its Washington, D.C. headquarters, the Western States Regional Council of Carpenters Issues Committee contributed $450,000, and the Northern California Carpenters Regional Council Issues PAC contributed $450,000 — a combined $1,700,000 from the Carpenters ecosystem alone, per FPPC records. The union's financial logic differs from the developers' but points in the same direction: if transfer taxes reduce the volume of large real estate transactions, and fewer transactions mean fewer construction projects, union members lose work hours. The Carpenters' position is an employment protection calculation, not an ideological one.

The Howard Jarvis Taxpayers Association, best known as the original proponent of Proposition 13 in 1978, provides the public framing for the campaign. HJTA President Jon Coupal told CalMatters in April 2026 that developer and investor frustration with Los Angeles's ULA tax was the catalytic force behind the statewide proposition effort, stating: 'I think ULA was not just the straw that broke the camel's back, but the redwood tree that broke the camel's back.' HJTA's institutional role is to supply taxpayer-rights language and organizational credibility to what the FPPC contribution records show is primarily a real estate industry and tech-billionaire financial operation. Whether HJTA made direct monetary contributions to the supporting committees is not determinable from available source materials.

The public interest argument advanced by supporters — that ULA has slowed new construction, including affordable housing development, in Los Angeles — is cited by CalMatters but the specific studies and researchers making this causal claim are not identified in available reporting. The construction slowdown, if it exists and is measured, would need to be isolated from broader market factors including rising interest rates and post-pandemic corrections that affected construction markets statewide and nationally. The causal link between the transfer tax and reduced housing supply is the operative justification for the measure's 'affordable housing' marketing, but that justification rests on contested empirical ground that the available public record does not definitively resolve.

What the public record does resolve is the financial architecture. A Google co-founder, a leading Silicon Valley venture capitalist, the largest real estate trade association in California, and the national and regional infrastructure of the Carpenters union have together committed at least $12,700,000 of the $14.4 million in documented contributions to a measure whose primary legal effect is to eliminate a category of tax that falls most heavily on sellers and developers of properties valued above $5 million. The measure is on the November 2026 ballot. The voters of California will decide whether it becomes law.

What remains hidden is substantial. The FPPC Top 10 list as captured in available source documents is cut off after six contributors — ranks 7 through 10 are not publicly summarized in the materials reviewed for this report. The individual contribution amounts from Sergey Brin and John Doerr personally are reported only at the intermediary committee level; their specific personal sums and the dates of those contributions are not broken out in the top-line FPPC data. Whether 'Building a Better California' has additional donors beyond Brin and Doerr is unknown from available sources. HJTA's direct financial role, if any, is undocumented. The instruments that would answer these questions are specific: Form 460 Schedule A filings for both supporting committees and for 'Building a Better California,' Form 497 large-donor disclosures for Brin and Doerr personally, and the complete FPPC Top 10 table for ranks 7 through 10 — all retrievable directly from the California Secretary of State's Cal-Access public database.
