What is required of a person who prepares designs related to a building?

The correct answer focuses on the requirement that individuals involved in preparing designs related to a building must adhere to the qualifications established in the building code. Building codes are comprehensive sets of regulations that ensure safety, structural integrity, accessibility, and compliance with various legal standards. These codes are developed to protect public health and safety, and they specify the minimum design and construction requirements for buildings.

Individuals who prepare designs must demonstrate competency and be familiar with these codes to ensure their designs meet all necessary legal and safety standards. This necessity for knowledge and compliance with the building code is what establishes an individual's qualifications in this context. While other qualifications, such as formal education or licensing, may be beneficial or required in certain circumstances, the foundational aspect remains the adherence to the qualifications laid out in the building code.
