San Francisco City Attorney Details Legal Actions Challenging Trump Administration Policies Affecting Funding, Housing, Immigration, and Governance
Overview
San Francisco City Attorney David Chiu has outlined a fast-expanding docket of litigation involving the city and the Trump administration, centered on federal funding conditions, immigration-related directives, homelessness programs, and executive-branch restructuring. The cases span multiple federal courts and, in several instances, have resulted in emergency orders or preliminary injunctions that temporarily pause challenged federal actions while litigation continues.
Sanctuary-jurisdiction funding dispute revived in 2025
One of the highest-profile matters reprises a legal fight from President Donald Trump’s first term: federal efforts to pressure so-called sanctuary jurisdictions by threatening to withhold federal funding. On April 24, 2025, a federal judge in San Francisco issued a preliminary injunction blocking the administration from denying or conditioning federal funds based on local sanctuary policies. The case was filed February 7, 2025, with San Francisco and Santa Clara County leading a multi-jurisdiction coalition.
The dispute centers on the extent of federal authority to use funding as leverage over local law-enforcement and immigration-cooperation decisions. The injunction, while not final, restrains the government from taking a range of direct or indirect steps to withhold funds from the plaintiff jurisdictions while the case proceeds.
Homelessness and housing grants: contested federal conditions
A separate line of litigation targets new conditions attached to homelessness and housing funding streams. San Francisco joined a lawsuit filed May 2, 2025, challenging conditions tied to the U.S. Department of Housing and Urban Development’s Continuum of Care grants—funding that provides the city more than $50 million annually for homelessness programs. In early May 2025, a federal judge issued a temporary restraining order halting enforcement of the challenged conditions against the plaintiff jurisdictions, and subsequent court action broadened relief to cover certain housing and transportation grant conditions.
Later in 2025, additional litigation addressed further federal restrictions affecting homelessness programming. On December 19, 2025, a federal judge issued a preliminary injunction that temporarily blocked HUD restrictions challenged by a coalition that included San Francisco and Santa Clara County, and that litigation remains active.
Emergency and disaster preparedness grants
In October 2025, San Francisco joined other local governments in a lawsuit challenging conditions placed on emergency and disaster preparedness grant funding administered through federal homeland security and emergency-management programs. The suit alleges the new conditions are unlawful and unrelated to the purposes of the grants, which support activities such as firefighting capacity, port and transit security, counterterrorism, and hazard mitigation.
Claims over executive-branch reorganization
San Francisco and Santa Clara County also sued over an executive order directing large-scale federal workforce reductions and reorganization. On May 9, 2025, a federal judge issued an emergency order pausing implementation while the case moves forward, reflecting the courts’ scrutiny of whether major structural changes to federal agencies can proceed without congressional authorization.
Key themes across the city’s lawsuits
Whether federal agencies may impose new, policy-driven grant conditions without clear congressional authorization.
How far the executive branch can go in using funding leverage to influence local governance and law-enforcement policy.
Whether rapid federal restructuring and workforce reductions comply with statutory and constitutional constraints.
Across multiple cases, courts have issued temporary or preliminary orders that preserve existing funding frameworks and agency operations while judges consider the legality of the challenged federal actions.
Several of these disputes remain in active litigation, meaning outcomes could shift as courts reach final rulings or appellate review. For San Francisco, the cases collectively carry significant implications for local budgets, homelessness services, emergency preparedness planning, and the city’s longstanding approach to immigration-related public safety policy.
