Private investigation in Baltimore covers surveillance, background and due-diligence research, and fraud or misconduct inquiries handled by a state-licensed investigator.
In Baltimore, demand for private investigation is driven by Maryland's largest security market and talent pool and a major East Coast port and its warehouse belt. The sectors that most rely on this service include port and logistics, healthcare and research, sports and events, with specific needs in areas such as the Port of Baltimore and its industrial belt, the Inner Harbor and downtown, the Johns Hopkins and hospital campuses. The city's main security concerns — cargo and container-yard theft and healthcare workplace violence — make working with a licensed, professional provider a priority investment for businesses and homeowners.

Before you hire
A buyer's guide to hiring a private investigator in the US: what PIs can and cannot legally do, state-by-state licensing, real hourly rates and retainers, how to vet a firm, and when to hire through a lawyer instead.
Read the private investigation buyer's guidePrivate security in Maryland is licensed at the state level by the Maryland State Police, Licensing Division. A legitimate company operating in Baltimore holds a a Security Guard Agency License, which means it has cleared Maryland State Police'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 Maryland, operating without a license is misdemeanor (Md. Code, Bus. Occ. & Prof. §§ 19-601, 19-607). Providing security guards for hire without a Security Guard Agency License (Bus. Occ. & Prof. § 19-601) is a misdemeanor under § 19-607, punishable by a fine of up to $1,000 and/or up to 1 year imprisonment; the Secretary may additionally levy administrative fines up to $5,000 per violation (capped at $10,000 per 2-year license term) for violations of §§ 19-313 and 19-408.

We use the city's own reported incident data instead, mapped to 269 Baltimore neighborhood — which is the more useful view anyway, since risk inside a city varies far more than it does between cities.
