What is the purpose of requiring professional review of residential construction plans?

Requiring professional review of residential construction plans primarily serves the purpose of ensuring that the plans comply with all relevant building codes and regulations prior to the start of construction. This process is critical because building codes are established to promote safety, health, and welfare for occupants as well as for the general public. By having a qualified professional review the plans, issues related to structural integrity, fire safety, sanitation, and energy efficiency can be addressed early on, minimizing the risk of costly modifications or dangerous conditions arising during or after construction.

While saving time and reducing costs can be beneficial outcomes of a thorough professional review, this is not the principal purpose of the requirement. The goal is more focused on compliance and safety rather than just efficiency or cost-effectiveness. Providing aesthetic advice is also not a primary reason for a professional plan review; aesthetics are often subjective and may vary based on the preferences of the homeowner or designer. Lastly, limiting the number of contractors involved in a project is not related to the review of the plans but rather pertains to project management and organization.
