Early life and career

Sonja Trauss was born in 1980or1981. She grew up in Germantown, Philadelphia. [1] Her father, Irwin Trauss, was a housing lawyer who represented homeowners facing foreclosure. She graduated from Temple University with a degree in philosophy after advocating for skateboarders in Love Park. [1] [2] She started a PhD in Economics at Washington University in St. Louis and left early with a master's degree. [3] Trauss moved to El Cerrito, California to care for a relative, and then moved to West Oakland, working at times in a bakery and then a math teacher. [3]

Housing advocacy

Bay Area Renters Federation

In 2013 or 2014, upset by housing costs, Trauss began writing letters going to government hearings in support of housing projects. [4] [5] She signed her letters as the Bay Area Renters' Federation (SF BARF). Trauss gained attention at public hearings and on Twitter for provocative statements. [6] SF BARF's mailing list grew to a few hundred and dozens began to attend public hearings to support housing. She received financial support from Jeremy Stoppelman. [7] [8] In 2015, Trauss raised enough funds to advocate full-time. [9]

In 2015, SF BARF launched a campaign to change the leadership of the local chapter of the Sierra Club, arguing that the chapter's opposition to development was detrimental to the mission. [10] [11] The campaign failed. [12]

In 2016, Trauss was an organizer for a political action committee to elect Scott Wiener to the State Senate, beginning to formalize a group that would campaign in elections. [13]

Supervisor candidacy

In 2017, Trauss announced she was running for San Francisco Supervisor in District 6, representing the Tenderloin, South of Market, and Mission Bay neighborhoods. [14] In the 2018 ranked choice election, she finished third with 19% of the vote, losing to Matt Haney.

In 2015, Trauss founded California Renters Legal Advocacy Fund (CaRLA) with others to sue cities that reject housing projects and violate the Housing Accountability Act. [15] CaRLA intervened on behalf of developers in Sausalito, Berkeley, and San Mateo—typically wealthier communities that reject new housing—and succeeded in getting project approvals. Their lawsuit in Lafayette on a set of apartments with 315 homes resulted in a settlement but no change in the project. [15]

As of 2022, Trauss is the Executive Director of YIMBY Law, a legal nonprofit that uses laws to ensure governments follow housing laws encouraging more new housing. In 2022, YIMBY Law raised money to hold San Francisco in compliance with housing law. [16] [8] In 2023, YIMBY Law sued cities for missing a state-mandated deadline for updating their housing plans. [17] In 2024, Trauss announced that YIMBY Law would be expanding outside of California. [18]

Controversies

In 2017, after Trauss equated opposition to a housing project in the Mission District to Donald Trump's hostility to immigrants, Supervisor David Campos credited Trauss for changing his mind and supported an appeal of a housing project. [19] [14]

In 2018, at dueling rallies over California Senate Bill 827, Trauss moved into the opposing crowd and was escorted away by a sheriff's deputy. [20] [21]

Personal life

As of 2018, Trauss is married and has one child. [21]
