Which statement about additions, alterations or repairs to a mechanical system is true?

• A. Minor additions, alterations or repairs do not require permits or inspections.
• B. The entire system must conform to the current mechanical code.
• C. The addition, alteration or repair must conform to the requirements of a new system.
• D. Additions, alterations or repairs are exempt from current code requirements.

Answer: (C)

When you add to, alter, or repair a mechanical system, the work must meet the current code requirements for a new installation for the portions being changed. This ensures the updated parts integrate safely with the rest of the system and comply with today’s safety, efficiency, and performance standards. Permits and inspections are generally required to verify this compliance, so the idea that minor work is exempt or that the entire system must be brought up to current code without regard to the altered portion isn’t correct. The requirement applies to the changed sections to ensure new work aligns with current, proven standards.
