Maintenance or testing when conducted by someone other than an owner must be conducted by what?

• A. A registered firm
• B. An uncertified contractor
• C. A licensed electrician
• D. A licensed plumber

Answer: (A)

The requirement is that maintenance or testing done by someone other than the owner must be carried out by a registered firm. This ensures that the work is performed under an organized, accountable entity that can provide proper oversight, qualified personnel, and documented records for safety and compliance. A registered firm is equipped to sign off on official reports, calibrations, and certifications and to maintain traceable documentation, which individual tradespeople or uncertified contractors cannot guarantee. While a licensed electrician or licensed plumber has individual credentials, the rule here focuses on the organization performing the work being registered, not just the person’s trade license.
