Identify the primary regulation governing building codes in Florida.

The primary regulation governing building codes in Florida is the Florida Building Code. This comprehensive code sets forth the standards and requirements for construction and renovation projects across the state. It covers various aspects, such as structural integrity, safety, installation of systems, and accessibility, ensuring that all buildings meet specific quality and safety criteria. The Florida Building Code is regularly updated to reflect advancements in construction practices, technology, and materials, which helps maintain safety and resilience against natural disasters, particularly hurricanes.

Other options listed, while relevant to certain aspects of construction or business regulation, do not specifically serve as the main governing document for building codes in Florida. Therefore, focusing on the Florida Building Code is essential for anyone involved in construction to ensure compliance and safety in all building projects.
