Indivisible SF Endorses the Affordable Housing Guarantee Act

Indivisible SF endorses the Affordable Housing Guarantee Act on the San Francisco ballot in November 2026! Voters can ensure that existing Prop I transfer tax revenues be spent on truly affordable Social Housing, rent relief and eviction protection for people of all income levels. VOTE YES on the AHGA and work to help it pass. 

In 2020, San Francisco voters passed Proposition I, a graduated real estate transfer tax on luxury property sales over $10 million to fund social housing, rent relief and eviction protection.  Voters concurrently passed Proposition K, allowing the city to acquire and develop 10,000 units of city-owned municipal housing. The San Francisco Board of Supervisors unanimously passed legislation to use the Prop I tax revenue for social housing.

In 2021-2022, more than $200 million in Prop I funds supported solutions to the housing affordability crisis, including launching the largest rent-relief program in US history, which prevented 20,000 evictions. Five sites were acquired to develop more than 500 homes and Prop I revenue funded the development of another 60 affordable homes for educators, invested $20 million in public-housing repairs, committed $10 million to fix broken elevators in permanent supportive housing, and made an unprecedented investment in community land trusts that prevent displacement and provide permanently affordable homes for San Franciscans. All forward progress came to a halt in 2023, when Mayor London Breed, a Prop I opponent, ended Prop I housing support and diverted all funds to other projects. 

In February 2026, San Francisco Mayor Daniel Lurie and District 5 Supervisor Bilal Mahmood with the support of San Francisco real estate lobbyists, introduced the Balanced Update to Incentivize Local Development (BUILD) Act, a legislative package designed to reduce transfer tax rates on large real estate transactions. The BUILD Act would have overturned Prop I and restored San Francisco’s transfer tax rates to pre-2020 levels for large transactions. The BUILD Act died without a hearing. However, real estate lobbyists continue to push for similar policies in Sacramento and San Francisco.

The ongoing threats to voter-approved Prop I social housing galvanized Dean Preston and the San Francisco Democratic Socialist chapter to introduce the Affordable Housing Guarantee Act (AHGA). AHGA closes the loophole that allows redirection of Prop I revenue towards non-housing related projects. Prop I is a general fund tax, and only half of the revenue has been used for affordable housing. AHGA changes the Prop I designation from general tax revenue to dedicated tax revenue, ensuring that all funds will fund housing. To guarantee that Prop I funds are used for affordable housing, housing advocates gathered over 20,000 signatures to put AHGA on the November 2026 ballot.

Based on the success of Measure U in LA, another dedicated transfer tax that has survived legal challenges in California, AHGA will fulfill the will of the voters by directing 100% of Prop I funds towards addressing the housing affordability crisis in San Francisco. Supported by Chyanne Chen and Jackie Fielder and aligned with the Public Bank proposition, AHGA is polling at 67% approval among voters, attracting support from both middle- and low-income residents. In order to pass AHGA, advocates are working to build endorsements and raise money to support public education.
