Must exterior walls extend to the height required by the requirements of parapet walls?

The statement is true because exterior walls are required to extend to the height mandated by the specific building codes regarding parapet walls. Parapets serve crucial functions, including preventing water intrusion, providing a safety barrier, and contributing to the overall architectural design of a building. Building codes will stipulate the required height of parapets based on various factors such as building occupancy, location, and surrounding structures. Ensuring that exterior walls extend to meet these requirements is essential for compliance with safety regulations, structural integrity, and effective weatherproofing. Proper construction that adheres to these heights helps to prevent issues like leakage, structural failure, or safety hazards that could arise from inadequate parapet design.
