Drawings must be prepared by a licensed architect or engineer for obtaining a permit when the floor area is 4000 square feet or more. This requirement is rooted in safety and structural integrity concerns. Larger structures often present more complex design challenges, necessitating professional expertise to ensure that they meet building codes and safety standards. Licensed architects or engineers are trained and qualified to address these complexities, which may include considerations such as load-bearing constraints, compliance with local zoning laws, and adherence to safety regulations.

Structures with smaller floor areas typically do not require the same level of detailed design oversight, as they can often be handled by individuals who may not have formal architectural or engineering credentials. Thus, the threshold of 4000 square feet serves as a guideline for ensuring that only structures that necessitate professional input are subject to this requirement. Understanding this aspect is crucial for contractors to navigate the permitting process effectively and ensure compliance with state regulations.
