What is the significance of obtaining a certificate of occupancy?

Obtaining a certificate of occupancy is crucial because it serves as official confirmation that a building complies with all relevant building codes and regulations, making it safe for occupancy. This document is typically issued by a local government agency after inspections have taken place, ensuring that the construction meets structural integrity, safety standards, and zoning laws. Without this certificate, a building cannot be legally occupied, which protects public health and safety by ensuring that only compliant buildings are used for their intended purposes.

The other options address aspects related to construction and property use but do not correctly represent the primary role of a certificate of occupancy. Option A discusses environmental standards, which, while important, are not the primary purpose of the certificate. Option C refers to warranties, which are typically separate legal documents concerning the quality of work performed. Option D inaccurately limits the necessity of a certificate of occupancy to only commercial buildings, as residential properties also require this certification to ensure they are safe for habitation.
