Federal agents have used worker disguises in documented operations, while California officials warn about fake ICE officers. Here’s how residents can verify who is at the door.
A person in a hard hat and high-visibility vest may look like a utility worker. But recent federal enforcement operations have raised a difficult question for California residents: How do you know who is actually standing outside your door?
The question became particularly relevant after a June 20, 2026, operation in South Los Angeles in which people dressed as municipal electrical workers reportedly approached a home and asked a resident to move a vehicle. After he did, armed agents emerged from unmarked vehicles and arrested him.
The U.S. Department of Homeland Security said the operation was conducted by U.S. Marshals, not Immigration and Customs Enforcement (ICE). DHS also said ICE officers do not disguise themselves as utility workers and that ICE personnel identify themselves when conducting operations. The person arrested was later transferred to ICE custody.
That distinction matters. Federal law-enforcement agencies are not interchangeable, and labeling every federal operation as an ICE operation can create confusion about who is actually acting and under what authority.
But the underlying concern is broader: legitimate utility workers, federal officers using deceptive tactics and people impersonating law enforcement can potentially look very different to a resident standing behind a closed door.
Three very different possibilities
California residents may encounter at least three different situations.
A legitimate utility worker. A city or utility employee may genuinely need access to equipment, a meter or infrastructure.
A federal law-enforcement operation. The South Los Angeles case provides a documented example in which U.S. Marshals were reported to have used the appearance of municipal utility workers as part of an operation. Separately, ICE has been documented using a construction-worker disguise in an undercover operation outside California. EL PAÍS’s reporting on federal agents using disguises
An impersonator or scammer. California Attorney General Rob Bonta has warned residents about people pretending to be ICE officers and using immigration fears to scam or intimidate people.
The three situations can have very different legal consequences. That is why appearance alone is not a reliable way to establish someone’s identity.
What should you do if someone claiming to be a utility worker comes to your door?
You do not have to open the door simply because someone is wearing a uniform, vest or hard hat.
Instead:
Keep the door closed. Speak through the closed door or another secure barrier.
Ask who they work for. Request the person’s name, agency or company and employee identification.
Verify independently. If the person claims to represent a utility, call the utility using a telephone number you obtain independently—not a number supplied by the person outside.
Don’t rely on appearance alone. A company vehicle, uniform or identification badge can provide information, but residents should still verify unexpected visits when something does not seem right.
LADWP’s customer guidance on immigration enforcement and utility-worker verification specifically tells customers that LADWP team members and contractors carry photo identification, and advises customers to ask for identification and call LADWP to verify an employee’s identity if they are unsure.
If someone claims to be a law-enforcement officer, the situation is different. Residents should avoid physically confronting or attempting to detain the person. If there is an immediate threat to safety, call 911.
What about California’s identification laws?
California lawmakers have attempted to make federal enforcement operations more transparent.
The state’s No Vigilantes Act included a requirement that non-uniformed federal law-enforcement officers display visible identification while conducting operations in California.
But that requirement is not currently enforceable against federal officers.
In April 2026, the U.S. Court of Appeals for the Ninth Circuit blocked California from enforcing the identification requirement against federal officers, concluding that the state likely could not directly regulate the federal government’s operations in that way.
That legal fight is part of the broader California immigration-enforcement landscape. Parriva has also written about how California courts are addressing other disputes involving federal immigration arrests in our recent report, “A California Judge Just Ruled on Warrantless ICE Arrests. What Does it Mean for Deportations?”
That means residents should not assume that California law currently guarantees that every federal officer operating in the state will display the identification California lawmakers sought to require.
What if the person is actually an immigration officer?
Immigration officers have identification and arrest requirements under federal regulations. Federal regulations generally require an immigration officer making an arrest to identify themselves as an immigration officer and state that the person is under arrest and the reason for the arrest as soon as practical and safe.
But that does not mean every encounter with a federal officer can be reduced to a simple rule about whether an officer is wearing a badge or uniform.
Home-entry questions are also more complicated than a simple “show me a warrant” rule. The type of warrant, the circumstances of the encounter and the agency involved can matter.
For that reason, residents who are concerned about an immigration-enforcement encounter should seek advice from a qualified legal-aid organization rather than relying on a generalized social-media rule.
The California Attorney General’s Office also maintains a system for reporting potentially unlawful conduct by federal law-enforcement agents, including alleged unlawful searches, arrests or detentions.
Parriva has also explained the broader role of ICE in California and across the country in “Born From 9/11, ICE Now Spends Its Time on Something Else Almost Entirely”.
The other danger: fake officers
There is another reason residents should be careful about assuming that everyone claiming to be federal law enforcement is actually an officer.
In March 2025, Attorney General Bonta warned Californians about reports of people impersonating ICE officers and other immigration-related scams.
A person exploiting fear of immigration enforcement may attempt to obtain money, personal information or access to a home or business.
That makes independent verification important, but it also means residents should not assume that every suspicious-looking person is a federal agent.
For residents, the practical lesson is simple: don’t determine someone’s identity solely by what they are wearing.
If an unexpected person arrives claiming to be a utility worker, keep the door closed, request identification and verify the visit independently. If the person claims to be law enforcement or immigration authorities, avoid confrontation and seek qualified legal advice about your rights.
In a climate where legitimate workers, federal officers and impersonators can all become part of the same public conversation, knowing who is actually at the door may be the most important first question.
