Tech Tuesday: Grandfathering and Partial Sprinkler Systems


Virtual Classroom, Adobe Connect, Virtual  
Tuesday, June 20, 2023 12:30 PM - 1:30 PM   iCalendar Eastern Standard Time

Existing buildings and existing fire sprinkler systems can have a “grandfather” status. Grandfathering is a practice in codes and standards to allow nonconforming buildings and systems to remain in service. Renovations, changes of occupancy, new processes, extending systems, and more can trigger new construction requirements in existing buildings…or not.  Often when new fire sprinkler systems are triggered for existing buildings, codes and standards permit partial systems to protect the new portion and not the entire building. Partial fire sprinkler systems, limited-area systems, engineered life safety systems, Dorothy-Mae and more are just a few terms used by codes and standards that mitigate the full application of NFPA 13.
