When must construction not proceed regarding insurance coverage?

Construction must not proceed unless the chief building official has been notified about the required insurance because this notification is essential for compliance with local regulations and safety standards. The mandatory insurance coverage protects both the contractor and the party hiring the contractor from potential risks associated with construction activities, such as property damage or accidents. Without this notification and associated proof of coverage, the construction project may not meet the necessary legal requirements, leading to possible fines, work stoppages, or liability issues. Ensuring that the chief building official is aware of the insurance status is vital to maintaining lawful and secure construction practices.
