Fremont, California passed a strict ordinance to ban homeless encampments on all public properties, including parks, on a 6-1 city council vote on Tuesday night.

A California city voted to criminalize “aiding” and “abetting” homeless camps Tuesday – an unusual move that advocates say could stifle aid to help for people who need it.

The ordinance, which prohibits camping on all public property and allows prosecutors to criminally charge anyone “aiding” or “abetting” a homeless camp.

Outreach workers in the California city of Fremont worry the new homelessness ordinance could target them, despite assurances from the city.

Fremont has enacted one of the most restrictive homeless encampment bans in California, sparking backlash from advocates and nonprofits who fear the ordinance could criminalize efforts to help those who are unhoused.

Fremont’s plan to ban homeless camps anywhere in the city has the potential to be the most forceful response yet in the Bay Area to a landmark U.S. Supreme Court ruling this summer granting officials broad authority to police homelessness — and could have ripple effects across the region.
