What is the maximum width that a chimney may be constructed before a saddle or cricket is required?

The maximum width that a chimney may be constructed before a saddle or cricket is required is 30 inches. This requirement is established to ensure proper water drainage and to prevent water pooling around the chimney. When a chimney exceeds this width, a saddle or cricket must be installed to direct water away from the chimney, reducing the risk of leaks, water damage, and deterioration of the roofing materials around the chimney.

This regulation is important in maintaining the structural integrity and longevity of both the chimney and the roof. Therefore, understanding the specifications regarding chimney width is crucial for general building contractors to comply with building codes and ensure effective water management.
