Hiring security in Union City: common questions
- Do security guards in Union City need a California licence?
- Yes. Guards working in Union City must hold a California guard registration, and the companies employing them must hold a Private Patrol Operator licence from the Bureau of Security and Investigative Services. Ask for both numbers before you sign anything.
- How do I check a Union City security company before hiring?
- Confirm the Private Patrol Operator number with BSIS, ask for a current certificate of insurance, and request references for sites of a similar size to yours.
- Which areas around Union City do these companies cover?
- Coverage is stored per city. Most providers listed here also cover other Alameda County cities, and each card states whether the company is based in Union City or travels in to serve it.
- What does Security Explorer publish about Union City companies?
- We publish only listings that have passed manual review. We show a licence as checked only when we hold a dated record of that check, and featured placement is a paid position rather than a recommendation.
