In Maryland, a licensed fire sprinkler contractor is required to install, repair, modify or lay out fire sprinkler systems in residential and commercial buildings. Read the Maryland fire inspection rules.
Every licensed sprinkler contractor must have at least one Designated Qualified Individual who meets the criteria for its license class. How companies are licensed in Maryland.
Fire alarm systems are tested every year and looked over every 6 months under NFPA 72, and who may test them depends on the state. Fire alarm inspection rules by state.
Look up a company by name or license number, then confirm it on the state's list.
Company names, license types, numbers and phones as the state publishes them. Out-of-state companies show their home town. A listing above means we also matched the company on Google.
