A local news report has examined why numerous structures in Las Vegas without fire sprinklers are still considered code-compliant. The investigation by KLAS 8 News Now centers on the distinction between new construction, covered by a 2019 ordinance mandating sprinklers in single-family homes, and older buildings constructed before such rules were in effect.

While the 2019 ordinance has resulted in approximately 18,000 new homes being equipped with fire sprinklers, a significant stock of older buildings legally operate without them. These structures are typically 'grandfathered' in, meaning they comply with the code that was in place at the time of their construction. Unless they undergo major renovations that trigger modern code requirements, they are not mandated to be retrofitted with sprinkler systems.

This situation underscores a common challenge in fire protection: evolving safety standards and their application to existing buildings. For fire protection engineers, contractors, and authorities having jurisdiction (AHJs) in the Las Vegas area, the report is a reminder of the importance of understanding the specific history and nuances of local codes.

Professionals must be able to distinguish between requirements for new projects and the regulations governing existing structures to ensure accurate assessments, installations, and maintenance plans. A thorough knowledge of which codes apply based on a building's age and occupancy is critical for ensuring safety and compliance.
