About this exam
The ICC Residential Mechanical Inspector (M2) Certification Exam is for people seeking to demonstrate knowledge needed to inspect residential mechanical work against applicable codes. It is relevant to aspiring and practicing building inspectors, code officials, and professionals in residential HVAC and construction. The exam focuses on applying code requirements in inspection situations, including mechanical-code scope, plans and equipment identification, appliance installation and clearances, and residential heating equipment. It is a certification exam, not a general HVAC technician licensing test, so candidates should prepare for code-based inspection decisions.
Candidates should expect a computer-based, multiple-choice exam, but the current ICC exam bulletin is the authority for the question count, time limit, permitted references, and code edition. Preparation involves more than memorizing requirements: practice locating applicable provisions and applying them to plans, equipment, clearances, and field conditions. Review the current exam content outline alongside the referenced code books, since editions and exam details can change. A useful study plan combines focused topic review, timed questions, and careful analysis of why each answer is supported by the code.

- Use the current ICC M2 exam outline to organize review of residential mechanical scope, inspection requirements, system plans, equipment identification, appliance installation, clearances, and heating equipment.
- Practice locating code provisions in the references allowed for your exam, then answer timed, scenario-based questions; review explanations for both correct and incorrect choices.
- Confirm the applicable code edition, exam format, and permitted references in the current ICC candidate bulletin, and use those official materials to guide your final review.
