The Context
Mayor Lurie with early support from Supervisors Mahmood, Sauter and Dorsey are proposing to reverse Prop I (2020). The action is aimed to help jump-start the construction of thousands of housing units that are approved but stalled due to economic infeasibility.
According to the SF Planning Dashboard as of March 19, 2026 there are 74,810 pipeline units - gross, 46,938 units approved, and 3,107 authorized to start construction.
The History
In November 2020, San Francisco voters passed Proposition I, an ordinance increasing the City's property transfer tax rate on commercial and residential properties.
Increased the tax rate on properties valued between $10 million and $24,999 million from 2.75% to 5.5%
- Increased the tax rate on properties valued at $25 million or more from 3% to 6%.
The measure was a general tax, and revenues are deposited into the city’s General Fund.
The Proposal
The proposal would roll back former Supervisor Dean Preston’s 2020 ballot measure that doubled the transfer tax on large real estate deals.
- Reduce the tax rate from 5.5% to 2.75% when the consideration or value of the property conveyed equals or exceeds $10,000,000 but is less than $25,000,000.
- Reduce the tax rate from 6% to 3% when the consideration or value equals or exceeds $25,000,000; exempt from these reductions the transfer of single-family residences and reduce the penalties for delinquent real property transfer taxes
