Requires the installation of automatic sprinkler systems and emergency fire escapes in certain multi-family dwellings

This bill requires owners of multi-family buildings taller than two stories to install automatic sprinkler systems on every floor where people live and emergency fire escapes on every floor except the ground level. It applies to all such buildings regardless of age or historic status, removing common exemptions. Key provisions mandate sprinklers on all residential floors and emergency exits (including exterior stairways or ladders) on upper floors. The law takes effect immediately upon passage, directly affecting building owners in multi-family housing.
