Residential Building Inspector Practice Exam

Prefabricated walls must be installed in accordance with what?

1. Manufacturer's specifications

2. Local building codes

3. Building inspection regulations

4. Approved plans

The correct answer is: Approved plans

Prefabricated walls must be installed in accordance with the approved plans because these plans are specifically designed to ensure that the construction meets all required safety, structural, and aesthetic standards. Approved plans typically incorporate information about the dimensions, materials, and assembly specifications necessary for the prefabricated components. Following the approved plans ensures that the installation is consistent with what was reviewed and sanctioned by relevant authorities before construction began. This is crucial because deviations from the approved plans could lead to structural integrity issues or violations of building codes, potentially compromising the safety and compliance of the entire structure. While manufacturer specifications, local building codes, and building inspection regulations are all important for overall compliance and safety during construction, the primary directive for how prefabricated walls should be installed comes directly from the plans that have been formally approved by the local authority having jurisdiction. This ensures alignment with both the intended design and regulatory requirements.
