Final answer:
The direct enforcement of local building codes is the responsibility of municipal or county government agencies through the work of building inspectors who ensure construction projects comply with safety and quality standards.
Step-by-step explanation:
The responsibility for the direct enforcement of local building codes typically falls on municipal or county government agencies. These agencies employ building inspectors who review plans, issue permits, and conduct inspections at various stages of construction to ensure compliance with the local building codes.
These codes are in place to ensure that structures are safe and meet a set standard of quality. If a building is found to not comply with the code, the inspectors have the authority to issue violation notices and may halt construction until the issues are resolved.
