For log grading under ICC 400, the requirement of an accredited agency is essential because it ensures that the grading process is carried out by a recognized and qualified organization capable of adhering to specific standards and regulations. Accredited agencies demonstrate competence in evaluating and grading logs according to the established criteria, which contributes to the overall safety, quality, and reliability of wood products used in construction. This accreditation also allows for consistency in the grading process, which is vital for maintaining compliance with industry standards and building codes.

Other roles—such as a certified individual, a professional inspector, or a local authority—may play other functions in the broader context of home inspection and construction compliance, but they do not specifically provide the level of accreditation necessary for log grading as defined under ICC 400. This establishes the clear distinction in responsibilities and qualifications related to wood grading functions.
