Alarm Registration 

Baltimore City requires an alarm system contractor, monitor, and user to register with the Police Commissioner each year. There is no fee for users to register an alarm.  However, contractors and monitors must register and pay the appropriate fee. 

Contractors and Monitors 

A contractor is any person who installs, maintains, alters, inspects, administers, sells or services alarm systems.   

A monitor is any person who is in the business of monitoring alarm systems for the purpose of reporting an alarm system’s activation to the Police Department.  

Contractors and monitors must register and pay the appropriate fee ($50 per year) for each alarm system.
