Concord is the largest city in Contra Costa County and a commercial hub of the East Bay, with retail centers, office parks, healthcare campuses, and the redevelopment of the former Concord Naval Weapons Station. Shopping centers, commercial buildings, and BART-adjacent activity drive retail loss prevention, commercial coverage, and mobile patrol demand across the suburban core.
The providers below are ranked on merit, but the final check is yours. Work through these four steps before you sign anything in Concord:
Private security in California is licensed at the state level by the California Bureau of Security and Investigative Services (BSIS), Department of Consumer Affairs. A legitimate company operating in Concord holds a Private Patrol Operator (PPO) license, which means it has cleared California BSIS's ownership, background-check and insurance requirements. Ask for that license number in writing and verify it yourself — a certificate on the wall tells you nothing about current standing, since a license can be suspended or revoked.
Hiring an unlicensed company is a risk you carry. In California, operating without a license is misdemeanor (Cal. Business & Professions Code §7582.3). Operating as an unlicensed private patrol operator (or knowingly engaging a non-exempt unlicensed one) is a misdemeanor punishable by a $5,000 fine, up to one year in county jail, or both; falsely holding oneself out as licensed (badge, ID/business card, letterhead, or advertising) is a separate misdemeanor with a fine up to $10,000, and a conviction bars BSIS licensure for one year (five years on a second offense).
Concord scores 58/100 on our Crime Index (grade D), which makes it safer than 24% of the 759 US cities we track. The index is built from FBI Crime Data Explorer reports for a population of 123,703.
