For how many inspection visits must a special inspector complete written inspection reports?

The correct answer is that a special inspector must complete written inspection reports for each inspection visit. This practice ensures thorough documentation of the inspection process, allowing for a comprehensive record that can be referenced later. Each inspection carries unique observations and findings, and documenting these helps maintain compliance with safety regulations and standards.

By requiring a report for each visit, it ensures that any issues can be tracked over time, providing clarity on the status of construction activities and adherence to building codes. Furthermore, continuous documentation facilitates communication between the inspector, the contractor, and any relevant authorities, which is vital for resolving issues that may arise during the construction process.

The other options do not align with standard practices for inspections. Completing reports only for the first inspection, nonconforming inspections, or final inspections would create gaps in documentation, potentially leading to misunderstandings or oversights regarding the state of the work and safety compliance throughout the entire construction project.
