What Is QII Verification?
Quality Insulation Installation (QII) verification checks the installation of insulation and the building’s air barrier as part of California Title 24 energy compliance. Insulation performance depends on installation quality as well as the specified material. Gaps, compression and incomplete air sealing can reduce that performance.
An ECC rater provides independent field verification of applicable requirements. You may also see the term HERS rater on project documents or hear it from your contractor. Permit Boost reviews the project documentation to identify the required verification scope and reporting.
When Is QII Verification Required?
QII requirements depend on the approved Title 24 energy documentation, project scope and applicable code requirements. Not every ADU, remodel or construction project requires QII. Send us your approved energy documents, including the CF1R where applicable, so we can review the listed field-verification requirements with your project team.
Arrange inspections early. Air sealing may need to be inspected before insulation is installed, and insulation must remain accessible for the required checks before drywall or other finishes cover it. Contact us with your construction schedule to coordinate the applicable stages. If work is already covered, let us know before booking so we can discuss what remains accessible and the next steps.
Our QII Verification Services
We coordinate the applicable visual inspections and field checks for the approved project, then prepare the required rater documentation through the CHEERS registry.
- Review of QII requirements shown in the project’s energy compliance documents.
- Visual verification of applicable air-barrier and air-sealing details.
- Insulation installation checks, including coverage, fit and alignment with the air barrier where required.
- Clear communication of items needing correction and coordination of follow-up verification.
- Applicable CHEERS documentation and reporting after verification requirements are satisfied.
QII inspection is distinct from HVAC duct leakage testing, airflow verification and refrigerant charge verification. If your project needs those services too, we can review the full scope when you request a quote.
Who We Work With
We work with general contractors coordinating construction, ADU builders planning inspection stages, HVAC contractors referring projects with envelope requirements, and homeowners navigating their approved plans. We also coordinate with Title 24 energy consultants when the project team needs clarification of documented verification requirements.
