Mayor Daniel Lurie and Supervisor Bilal Mahmood, with support from the Building Trades, are pushing for this legislation. The act would slash San Francisco’s transfer tax on high-value property sales, undoing changes made by Proposition I back in 2020.
Supporters say the tax cut could jumpstart stalled multifamily construction and breathe new life into empty office buildings downtown. They see it as a much-needed boost for the city’s sluggish real estate sector.
But not everyone’s convinced. Folks in communities like Corte Madera are asking tough questions about what this could mean for their own local markets and the wider Bay Area economy.
Understanding the BUILD Act: Incentives vs. Impact
The BUILD Act targets property sales over $10 million, lowering the transfer tax that’s weighed on deals since 2020. Lawmakers behind the bill argue that higher taxes have scared off investors and slowed down important development, especially for multifamily housing.
They picture a future where lower taxes get projects moving again, spurring new construction and conversions. That, in their view, could mean more jobs and economic activity in San Francisco and even ripple out to towns like Tiburon and Belvedere.
The Developers’ Dilemma and the Critics’ Concerns
Supporters of the BUILD Act imagine cranes dotting the skyline and fresh developments springing up. Their hope is that making big property deals more attractive will unleash a wave of investment.
They believe this could mean more housing and modern office spaces, which would be a win for the whole Bay Area—including Larkspur and Greenbrae. But plenty of critics aren’t buying it.
Critics point out that the bill doesn’t require tax breaks to be tied to actual development. In practice, this could mean wealthy property owners get a tax cut even if they don’t build anything new.
For those worried about the housing shortage, that’s a big problem. They want real development, not just financial perks for people who already own valuable property.
Fiscal Realities: Revenue Shortfalls and Forecasted Swings
The money side of the BUILD Act is where things get especially heated. Since Proposition I, the higher transfer tax has brought in more than $500 million for San Francisco.
City officials estimate that rolling back these taxes could leave a $400 million hole over four years. That’s got a lot of people worried about what happens to city services, which folks all over the Bay Area rely on.
Supervisor Mahmood’s Revenue-Neutral Claims and Counterarguments
Supervisor Mahmood insists the BUILD Act can be revenue-neutral. He predicts a 20 percent bump in large property sales if the tax goes down.
He’s also floated a separate November ballot measure to tax foreclosure sales, hoping that will balance out any lost revenue. He says this two-pronged approach will keep the city’s finances steady.
Some analysts think a 20 percent increase in sales isn’t out of the question, but they’re not sure taxing foreclosures will make up the difference. There’s even an argument that a foreclosure tax could bring in more money than the transfer tax cut would lose.
So why not focus on those options first? It’s a fair question, especially for people skeptical of measures that seem to benefit wealthy property owners and big corporations, particularly near the Golden Gate National Recreation Area.
The Political Tightrope: Optics and the Path Forward
The political landscape around the BUILD Act feels messy, maybe even a bit precarious, especially for San Francisco’s Board of Supervisors. Cutting taxes for wealthy property owners—right now, with the city facing budget headaches—just doesn’t sound great to most people.
Plenty of folks in Marin, who often depend on San Francisco’s infrastructure, are keeping an eye on things. They’re hoping the city’s choices about revenue won’t end up hurting their own communities.
Everything could shift depending on how the June budget shakes out and what happens with Proposition D, which lands on the ballot at the same time. Both will probably have a big say in how much wiggle room San Francisco has financially and what the Supervisors decide.
Expect heated debates and plenty of behind-the-scenes chess moves as lawmakers try to figure out if the BUILD Act will actually kickstart the development everyone’s hoping for—or if it’s just going to drain much-needed city funds. Whatever happens, the effects will ripple out across the Bay Area, from Tamalpais all the way to the Pacific.
