What is the main purpose of the International Building Code?

The main purpose of the International Building Code is to establish minimum safety, health, and welfare requirements for buildings and structures. This code serves as a comprehensive set of regulations that local governments can adopt to ensure that structures are safe for occupancy and use, protecting both the occupants and the community at large. It covers various aspects such as structural stability, fire safety, sanitation, accessibility, and energy efficiency. These guidelines are critical for the construction industry as they help ensure uniformity in building practices, which ultimately aims to protect public health and safety.

While other options might play important roles in certain contexts—such as promoting sustainable practices or standardizing materials—these are not the primary focus of the International Building Code. This code is fundamentally concerned with establishing a baseline of safety and functionality in building design and construction.
