CSLB Contractor's Law & Business Practice Exam

Who may not approve a set of plans in the State of California?

1. Architect

2. Interior designer

3. Engineer

4. Owner-builder

The correct answer is: Interior designer

In California, the approval of a set of plans typically requires specific qualifications and credentials that are usually held by licensed professionals in architecture, engineering, or similar fields. The role of an interior designer, while essential in the design and aesthetics of a space, does not generally encompass the authority to approve plans for construction or major renovations that involve structural or safety aspects. Architects and engineers are regulated by state licensing boards and must adhere to rigorous standards. They have the training to ensure that plans meet legal, safety, and functionality standards. Owner-builders may construct their own homes and can manage projects without a licensed contractor, but they might still need to have the plans approved by relevant authorities for compliance with building codes and regulations. In essence, while interior designers contribute significantly to design projects, they lack the legal standing required to approve plans, which is why this choice is accurate in distinguishing who may not approve a set of plans in California.
