Modern homes contain a range of mechanical systems designed to add convenience to everyday life. A variety of building codes are in place to ensure these systems are safe and functional.

These codes don’t operate on an honor system, though. Code officials, like plans examiners and site inspectors, are responsible for assessing structures and enforcing compliance with applicable codes. Mechanical inspectors and plan reviewers assess mechanical systems.

Before you can perform these tasks in an official capacity, however, you must obtain a license from the Ohio Department of Commerce. What can you do with a mechanical code inspector or plans examiner license, and how do you qualify for licensure?

What Do Mechanical Code Officials Do?

There are two types of code officials — inspectors and plans examiners. Inspectors conduct on-site assessments of mechanical systems for established structures or new construction projects.

They may inspect HVAC and plumbing systems and components, as well as vents, ducts, boilers, and more. Inspectors look for potential hazards, create reports, and enforce code compliance. They may also issue permits.

Plans examiners perform a similar function but review plans before and during construction. They assess layouts, designs, and planned components to verify that they comply with applicable codes. These professionals must interpret plans and determine whether they comply before the plans are approved.

The goal of both professions is to ensure safe and functional mechanical systems that comply with the Ohio Mechanical Code.

Requirements to Obtain a License

You must have some industry experience to qualify for a mechanical code inspector or plans examiner license in Ohio.

Inspectors must complete five years of experience as an HVAC technician, including refrigeration, fuel gas, and heating piping systems that are subject to inspection. Alternatively, you may complete five years of experience as a full-time residential building inspector, residential building official, or residential mechanical inspector.

A plans examiner must complete five years of experience as a full-time mechanical inspector in a certified building department or five years as a full-time residential building inspector, residential building official, or residential mechanical inspector.

Once these requirements are completed, you must also pass the National Certification Program for Construction Code Inspectors (NCPCCI) testing for your trade.

NCPCCI Testing Requirements

Mechanical inspectors must pass the 4B Mechanical Inspector General Exam, consisting of 50 questions on topics like:

• Air distribution systems and piping systems
• Appliances and equipment
• Venting systems, combustion air, and fuel systems

The reference text for this test is the International Fuel Gas Code. Mechanical plans examiners must pass the 4C Mechanical Inspector Plan Review Exam. This test features 50 questions covering the same topics as the 4B exam, based on the International Fuel Gas Code and International Mechanical Code.

You will have two hours to complete each of these open-book exams, and you must answer at least 70% of the questions correctly to pass.
