Licensing and Plan Review
What this domain tests
This domain tests the business and administrative side: who may contract and install sprinkler work in Maryland, what a submittal must contain, and how review and inspection proceed.
Core rules
- Fire sprinkler contractors must hold a valid license issued by the Office of the State Fire Marshal, carry required insurance, and designate a qualifying individual.
- Only a licensed contractor may pull permits and perform the work; unlicensed contracting is a violation and can void inspections.
- Submittals typically include hydraulic calculations, shop drawings, a water supply test, manufacturer cut sheets, and a code analysis identifying the applicable edition and standard.
- Many AHJs require plans sealed by a Maryland-licensed professional engineer or prepared by a qualified designer; confirm the requirement with the AHJ before submitting.
- Review produces approved plans; installation then requires rough-in and final inspections, with hydrostatic and acceptance test records.
Worked example
A contractor submits a 13R package for a four-story apartment building. The reviewer checks the license number and insurance certificate, verifies the code edition and that 13R is permitted for the height and occupancy, reviews the hydraulic calculation for the correct density and remote area, and confirms a current water supply test. Missing items generate a comment letter; the permit is not issued until they are resolved.
Traps
Submitting an NFPA 13R design where the code requires NFPA 13; using an expired license or missing insurance; relying on an old water flow test; omitting the code analysis page; scheduling inspection before test records are available.
