287(g) in California: What It Is and How Local Police-ICE Cooperation Affects You

What 287(g) actually is

Section 287(g) is a provision of federal law that allows local police and sheriff's departments to sign formal agreements with ICE. Under these partnerships, local officers are essentially deputized to perform immigration enforcement functions. They can question you about your status, look up federal immigration databases, and hold you in jail on behalf of ICE. In states without protective sanctuary laws, these programs have expanded rapidly.

Why California is different

California passed the California Values Act (SB 54) back in 2017 to limit this type of cooperation. It remains one of the strictest sanctuary laws in the country. The law explicitly prohibits local police and sheriffs from performing the duties of federal immigration agents, meaning California police departments cannot sign 287(g) agreements.

SB 54 also places tight restrictions on when local jails can honor ICE detainer requests. Most of the time, a local jail cannot keep you locked up past your scheduled release date simply because ICE asked them to. However, exceptions exist. If an individual has been convicted (not just arrested or charged) of specific violent crimes or serious felonies listed under the statute, local jails might still be able to cooperate with federal agents.

Where the gaps exist

While the law is clear on paper, reality on the ground often varies. Several advocacy groups have documented ongoing gaps in how different counties behave. For example, some California sheriffs circumvent the spirit of the law by posting jail release dates publicly online. It's a loophole: they aren't handing the individual over directly, but they're telling ICE exactly when to wait outside the facility doors. Because of this, your practical safety depends heavily on knowing how your specific county operates.

What to do if you believe SB 54 was violated

• Document the interaction: generally, it is in your interest to write down every detail immediately — the dates, exact times, badge numbers, and exactly what the officers communicated.
• Seek a legal review: if a local jail held you extra hours or shared your release details outside the statutory exceptions, you should have an attorney review your case.
• Connect with local advocacy groups: organizations tracking local jail behavior can help spot if a specific sheriff's department is developing an illegal pattern.
• Consider legal remedies: California courts have used mandamus actions (court orders forcing public officials to follow the law) to make local agencies comply with SB 54.

Why this issue matters to us

Holding local authorities accountable isn't a side project for this firm; it's the core of why we open our doors every day. California built these protections to safeguard immigrant communities. When a local police department ignores them, it becomes a direct violation of civil rights.

Frequently asked questions

Can California police departments have 287(g) agreements with ICE?

No. SB 54 bans local law enforcement from performing immigration enforcement functions, which rules out 287(g) deals.

Does SB 54 stop ICE from arresting people in California?

No, it doesn't. It stops local police from helping them, but ICE can still make independent arrests anywhere in the state.

Can local jails hold someone for ICE in California?

Usually, only under narrow exceptions. It usually requires a prior conviction for a serious or violent felony. Without that, holding someone past their release time is illegal.

What if my local sheriff's department is not following SB 54?

It happens. Legal tools like mandamus petitions can force them to stop. An experienced attorney can look at your county's actions and evaluate your options.

Does being in a sanctuary state mean I am completely safe from ICE?

No. Sanctuary protections limit local police cooperation, but they don't erase federal authority. Knowing this distinction helps you make safer decisions.
