Masonry chimneys must be constructed in compliance with which code?

The correct answer is the International Building Code because it serves as a comprehensive set of standards that govern the construction and safety of buildings, including the specifications for masonry chimneys. This code provides detailed requirements related to materials, design, structural integrity, and fire safety, ensuring that masonry chimneys can withstand various stresses and function properly within the overall building framework.

Using the International Building Code ensures that the construction of masonry chimneys aligns with best practices as recognized across many jurisdictions, which helps prevent safety hazards that could result from improper construction techniques or materials. This code also integrates considerations for ventilation and clearance to combustible materials, further promoting safety in building design.

While the other codes play significant roles in construction and fire safety, the International Building Code specifically addresses the structural and design requirements necessary for masonry chimneys.
