A California C-28 Lock and Security Equipment contractor license lets you install, maintain, and repair locks, doors, and access-control systems for hire. It requires passing CSLB’s C-28 trade exam and the Law & Business exam, plus at least four years of qualifying lock-and-security experience.
What does a C-28 license cover?
A lock and security equipment contractor evaluates, sets up, installs, maintains, and repairs doors and door assemblies, gates, locks and locking devices, and panic and fire-rated exit devices, including master key systems, security doors, and card-activated and electronic access control systems — excluding fire alarm systems. (Source: California Code of Regulations, Title 16, Section 832.28.)
How do I get a C-28 license?
You’ll need at least four years of qualifying lock-and-security experience within the last 10 years, a completed CSLB application, and passing scores on both the C-28 trade exam and the Law & Business exam. See our step-by-step application guide and current fee and bond breakdown.
