Over fierce objections from homeless advocates and service providers, Fremont, the Bay Area’s fourth-largest city, has adopted one of the strictest encamping bans anywhere in the region and California.

A California city voted to criminalize “aiding” and “abetting” homeless camps Tuesday — an unusual move that advocates say could stifle help for people who need it. In addition to making it illegal to camp on public property,

The action by the city of Fremont, California, comes after a Supreme Court ruling in June that emboldened communities across the country to limit protections for people without homes. The court’s decision in Grants Pass, Oregon v. Johnson lets cities ban homeless residents from sleeping outside, even when a community lacks indoor shelter beds.

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.

The council is considering passing an ordinance that would restrict camping on both public and private property. It would also prohibit “permitting, aiding, abetting or concealing” someone who is camping. Violators could face a fine of up to a thousand dollars or six months in jail.
