A plan to add thousands of historic landmarks to San Francisco's rolls was pitched as a feel-good preservation win. It has instead produced City Hall's first real brawl of the Lurie era — and ended with the supervisor most opposed to it losing the committee seat he needed to change it.

Supervisor Bilal Mahmood lost his place on the Land Use and Transportation Committee on Aug. 14, pushed off by a reshuffle that Board President Rafael Mandelman controls. Mahmood says the real reason was his campaign to amend the historic-preservation legislation Mandelman is carrying with Mayor Daniel Lurie — a bill that would make landmark designations far easier and could add thousands to a register that today covers only a sliver of the city. Mahmood contends each new designation quietly shrinks San Francisco's housing capacity. Off the zoning committee, he has lost the most direct route to force the city to prove otherwise.

San Francisco's roster of local historic landmarks runs to roughly 2,800 parcels in a city of hundreds of thousands. Mandelman and Lurie want it much bigger — a citywide survey aimed at nearly doubling the total, with thousands of new designations, as The Dissent reported in May. Backers frame it as overdue protection for neighborhood character and a fix for a designation process that can drag on for more than a year per property. Housing advocates counter that a landmark tag can make a parcel far harder to build on, at a moment when rents are spiking.

That policy tension has now curdled into a personal one.

Mahmood, who won the Tenderloin seat by unseating democratic socialist Dean Preston, wants an amendment forcing the city to measure the housing capacity each designation removes — and to claw it back by lifting height limits on other parcels. Mandelman treats that as a wrecking ball. He accused his colleague of trying to "hijack" the bill and said the amendment would "gut" it, he told the San Francisco Standard (external source, opens in a new tab).

Then he removed the room where that fight would happen. The reshuffle pulled Mahmood off both Land Use and the Government Audit and Oversight Committee and reassigned him to Public Safety and Neighborhood Services. His seat on the housing panel went to Supervisor Matt Dorsey; Mandelman said he wanted to preserve a YIMBY vote there and to shape committees that reflect where the full board actually sits, Mission Local reported (external source, opens in a new tab).

He accused his colleague of trying to "hijack" the bill and said the amendment would "gut" it, he told the San Francisco Standard.

The mechanics matter: zoning amendments run through the committee of jurisdiction. Without a seat, Mahmood can't carry his own. He said he might persuade another supervisor to introduce them but had no assurance one would. He called the demotion "disappointing" and "not a great signal of leadership," and rejected being cast as the antagonist, arguing it is misleading to treat ordinary democratic process as aggression. What he sees instead, he said, is a president reshuffling assignments to duck hard votes.

Mandelman declined to comment on Mahmood's claim that the removal was tied to the landmark bill, but he didn't disavow it either, describing Mahmood's handling of the legislation as "quite aggressive" and suggesting a simple no vote would have been the collegial path. He also flagged a broader "shift" in how the supervisor operates — a nod to Mahmood's recent accusation that Lurie and Supervisor Connie Chan had teamed up to sink his proposed vacancy tax.

Underneath it all sits a looming state Assembly race for Matt Haney's seat. Its timing is unsettled — the opening could come in 2027 or 2028, hinging on whether Sen. Scott Wiener wins the congressional seat he is chasing. Mandelman has already launched a campaign. Mahmood, who lost a bid for the same seat in 2022, calls a run now "premature" but hasn't closed the door; Mandelman says he believes Mahmood is weighing it, while denying the rivalry shaped his committee decisions.

For a mayor who sold City Hall on an "era of good feeling," this is an early stress test — a phrase Mandelman himself invoked in defending the reshuffle. The preservation bill keeps moving. But the question Mahmood wanted on the record — how many homes the city gives up each time it freezes a building in place — now has no sponsor on the committee empowered to ask it.
