Which person is MOST responsible for ensuring that the construction drawings are code-compliant?

The NCIDQ IDPX exam tests the designer’s understanding of professional responsibilities, particularly regarding code compliance in construction drawings. Code compliance ensures that the design adheres to building codes, accessibility standards, and life safety regulations.

Option A (Developer):The developer typically oversees the project’s financial and logistical aspects, but they are not responsible for creating or ensuring the code compliance of construction drawings. This role focuses on project management, not design.

Option B (Building owner):The building owner may be ultimately responsible for ensuring the building meets codes as part of their legal obligations, but they rely on the design team to produce compliant drawings. The owner does not create or directly verify the drawings.

Option C (Interior designer):This is the correct choice. The interior designer, as the professional preparing the construction drawings (or overseeing their preparation), is most responsible for ensuring that the drawings comply with applicable codes, such as the International Building Code (IBC), ADA standards, and local regulations. This responsibility is part of the designer’s role in producing a safe and compliant design.

Option D (Building inspector):The building inspector reviews the drawings and construction for code compliance during permitting and inspections, but they do not create the drawings or ensure their compliance during the design phase. Their role is to verify, not to design.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on professional responsibilities and code compliance.

“The interior designer is responsible for ensuring that construction drawings comply with all applicable building codes, accessibility standards, and regulations as part of their professional duty.” (NCIDQ IDPX Study Guide, Codes and Standards Section)

The NCIDQ IDPX Study Guide clearly states that the interior designer, as the creator of the construction drawings, is most responsible for ensuring code compliance during the design phase. This includes verifying that the drawings meet all relevant codes before submission for permitting, making Option C the correct answer.
