Which of the following is NOT a requirement under workmanship standards for licensed contractors?

The focus on workmanship standards for licensed contractors emphasizes the necessity to uphold certain criteria that ensure the quality and safety of construction work. Among these criteria, the requirement to perform all work in a professional and workmanlike manner is critical, as it directly impacts the reliability and safety of the completed project. Adhering to all applicable building codes within adopted jurisdictions ensures compliance with legal standards and promotes safety in construction, while completing work that meets the standards of similar licensed contractors aligns with the industry norms for quality and workmanship.

In contrast, the notion of hiring an inspector for jobs in cities that have not adopted building codes does not align with the fundamental principles of workmanship standards. Many construction projects are subject to regulations regardless of local code adoption, and the emphasis is typically on the contractor's obligation to ensure quality and safety through their own practices, rather than on the requirement to hire an inspector where building codes may not exist. Thus, this choice stands out as not being a requisite under standard workmanship criteria.
