International Mechanical Code 2024 | IMC 2024

The 2024 International Mechanical Code (IMC) is an essential professional reference for the design, installation, alteration, maintenance, and inspection of mechanical systems in buildings. Published by the International Code Council, it establishes minimum requirements using both prescriptive and performance-based provisions.

The code covers major areas of mechanical construction, including ventilation, exhaust systems, duct systems, combustion air, chimneys and vents, appliances, fireplaces, boilers, water heaters, pressure vessels, refrigeration, hydronic piping, fuel-oil piping, and solar thermal systems. It also includes referenced standards and appendices addressing topics such as chimney connector pass-throughs, permit fees, appeals, and clean-air delivery.

This edition introduces a cleaner single-column design, updated fonts, clearer table formatting, grouped figures, and QR codes that help readers identify code changes. Important technical revisions include updated refrigerant provisions, changes involving A2L and B2L refrigerants, new requirements for carbon-dioxide refrigeration systems, revised healthcare ventilation provisions, commercial dryer exhaust updates, steam-bath requirements, and additional roof-access safety provisions.

The 2024 IMC is valuable for HVAC contractors, mechanical engineers, architects, building inspectors, plans examiners, code officials, facility managers, construction professionals, instructors, and students. It can support system design, permit preparation, plan review, installation work, inspection, training, and examination study where the 2024 edition is specified.

Its organized format makes it easier to locate requirements during office, classroom, or jobsite reference. However, code adoption and local amendments vary, so customers should confirm the edition required by their jurisdiction, employer, project, or examination authority.
