An office building is categorized as which type of construction?

An office building is categorized as commercial construction because it serves the purpose of conducting business activities and accommodating various services. Commercial construction encompasses structures designed for income-generating activities, which includes office buildings, retail spaces, and other facilities used for trade and commerce. These buildings are typically designed with specific functionality in mind, fitting the needs of different businesses and organizations.

The term "commercial" reflects not just the physical structure but also the nature of its use, which focuses on economic activity and services rendered to the public or other businesses. This classification allows for more specific regulatory and zoning considerations that influence aspects like building codes, safety standards, and accessibility requirements, which are vital in commercial properties to ensure they are suitable for the public and employees alike.

In contrast, residential construction pertains to buildings designed for dwelling purposes, industrial construction relates to manufacturing and production facilities, and public construction usually refers to projects funded and owned by government entities, aiming to serve the community. Thus, an office building distinctly aligns with commercial construction due to its intent and functionality.
