Residential Building Inspector B1General Administration, Legal, and EnforcementMedium
An inspector is reviewing a set of construction documents for a new single-family residence. The plans specify a proprietary wall system that is not explicitly detailed in the 2021 IRC. The plans include an evaluation report from a recognized evaluation service (e.g., ICC-ES) for this wall system. What is the significance of such an evaluation report in the permit review process?
- AIt replaces the need for any on-site inspections of the wall system.
- BIt serves as evidence that the material or system complies with the intent of the code.
- CIt automatically approves the use of the proprietary system without further review.
- DIt is only required if the building official specifically requests it.
Show answer & explanationAnswer & explanation
Correct answer: B. It serves as evidence that the material or system complies with the intent of the code.
Evaluation reports (such as those from ICC-ES) provide a basis for the building official to approve materials or systems not explicitly addressed in the code. They offer independent evidence that the proprietary product meets the performance requirements and intent of the code, but the final approval still rests with the building official.
Why the other options are wrong
- A. Evaluation reports do not eliminate the need for on-site inspections to verify proper installation according to the report and approved plans.
- C. Evaluation reports provide evidence but do not automatically grant approval; the building official must still make the final determination.
- D. While official requests can be made, a proactive submission of such reports by the applicant is standard practice for proprietary systems.
Evaluation Reports (ICC-ES)
Documents issued by independent evaluation services that assess proprietary building materials, products, and systems for compliance with building code requirements.
- Provide evidence for alternative materials/methods approval.
- Used by building officials to make informed decisions.
- Do not replace the official's final approval or site inspections.
Memory trick: An ES Report Gives Code Intent, for Products Not Explicitly Sent.
