How many inches above both adjacent roofs must a fire wall terminate?

A fire wall must terminate at a height of at least 30 inches above both adjacent roofs to maintain adequate fire resistance and limit the potential for fire spread. This height is significant as it helps to create a physical barrier that prevents flames and heat from transitioning from one structure to another, ensuring safety in the event of a fire. Proper termination of a fire wall is crucial in protecting adjacent buildings, especially in commercial settings where structure proximity might increase the risk of fire spreading. Additionally, the 30-inch height requirement aligns with safety codes and standards, which have evolved to minimize hazards associated with fire risks in urban environments. In this context, terminating at precisely this height helps in complying with best practices and building regulations designed to enhance fire safety.
