2024 International Mechanical Code (IMC)

About the Book

2024 International Mechanical Code (IMC) is a comprehensive technical reference developed by the International Code Council (ICC) to establish minimum safety requirements for mechanical systems in buildings. It provides essential regulations and technical guidance for the design, installation, inspection, and maintenance of mechanical equipment and systems in residential, commercial, and other building environments.

The book covers a wide range of mechanical applications, including heating, ventilation, air-conditioning (HVAC), exhaust systems, ductwork, combustion air, boilers, refrigeration systems, chimneys, vents, and related mechanical equipment. Its provisions combine prescriptive and performance-based requirements, allowing professionals to apply established safety principles while accommodating new materials, technologies, and construction methods.

The 2024 edition introduces important updates addressing modern mechanical system requirements. These include revised provisions for A2L and B2L refrigerants, commercial dryer exhaust, outpatient healthcare facility ventilation, grease duct testing, steam baths, carbon dioxide refrigeration systems, and safer roof access through improved roof hatch landing requirements.

Designed for mechanical engineers, HVAC contractors, architects, builders, construction professionals, inspectors, and code enforcement officials, this publication serves as a practical resource for understanding mechanical code requirements and supporting safe, compliant building projects.

Whether used for professional reference, construction planning, technical education, inspections, or regulatory compliance, 2024 International Mechanical Code provides valuable guidance for professionals working with modern building mechanical systems.
