This section on alterations describes the differences that apply to alterations. Otherwise the procedures and requirements detailed in previous sections of NA1 shall also apply to alterations. For alterations, building owners or their agents may carry out the actions that are assigned to builders in previous sections of Appendix NA1.
Applicable procedures for registration of compliance documents described in Appendix NA1 shall also apply to alterations.
When compliance for an alteration requires diagnostic testing and field verification, the testing and field verification shall be completed for the permitted system or dwelling unit alone. Alterations to existing space conditioning systems are not permitted to be part of a designated sample group.
The building permit applicant shall submit or make arrangements for submittal of the required Certificate of Compliance information to the ECC-Provider and complete the applicable Certificate of Compliance documentation in accordance with the requirements in Standards Section 10-103(a)1 and 10-103(a)2.
When the enforcement agency does not require building design plans to be submitted with the application for a building permit for an alteration, any applicable registered Certificate of Compliance documentation specified in 10-103(a)1 is not required to be approved by the enforcement agency prior to issuance of a building permit, but shall be approved by the enforcement agency prior to final inspection of the dwelling unit, and shall be made available to the enforcement agency for all applicable inspections as specified in Standards Section 10-103(a)2A.
ECC-Raters or other authorized users of the Data Registry may provide documentation author support to facilitate the submittal of any required Certificate of Compliance information to the enforcement agency on behalf of the building owner or agent of the building owner, when such facilitation has been authorized by the building owner or agent of the building owner. The building owner or agent of the building owner who is eligible under Division 3 of the Business and Professions Code to take responsibility for the design specification for the alteration shall sign the Certificate of Compliance, to certify the information provided on the Certificate is true and correct, to certify conformance with Part 6, and shall submit the Certificate of Compliance to the enforcement agency for approval.
The building permit applicant or building owner or agent shall make available to the ECC-Rater a copy of the registered Certificate of Compliance approved by the enforcement agency.
The installer or field technician shall perform diagnostic testing and the procedures specified in Reference nonresidential Appendix NA1.4 and NA2.
When the installation is complete, the person responsible for the installation shall complete and sign the Certificate of Installation, and post a copy at the building site for review by the enforcement agency in conjunction with requests for final inspection. Alternatively, contingent upon approval of a Nonresidential Data registry, the enforcement agency may elect to view the certificates on an approved Data Registry. The owner or subcontractor shall also provide a completed signed copy of the Certificate of Installation to the ECC-Rater.
The field technician responsible for performing the acceptance test on the system shall complete the Certificate of Acceptance. The Certificate of Acceptance shall be signed by the system designer or installing contractor who is responsible for the system performance. A copy of the completed signed Certificate shall be posted at the building site for review by the enforcement agency in conjunction with requests for final inspection. Alternatively, contingent upon approval of a Nonresidential Data registry, the enforcement agency may elect to view the certificates on an approved Data Registry. The owner or subcontractor shall also provide a completed signed copy of the Certificate of Installation to the ECC-Rater.
The ECC-Rater shall verify that the Certificate of Compliance, Certificate of Installation, and Certificate of Acceptance have been completed for each unit having features requiring verification, and that the field technician’s diagnostic test results and all other Certificate of Acceptance information shows compliance consistent with the Certificate of Compliance for the system.
The enforcement agency shall not approve the alteration until the enforcement agency has received a completed Certificate of Installation as specified in NA1.4, Certificate of Acceptance as specified in Section NA1.5, and a copy of the registered Certificate of Verification as specified in NA1.6.
Third Party Quality Control Programs, as specified in NA1.7, shall not use group sampling for alterations. When a Third Party Quality Control Program is used, the enforcement agency may approve compliance based on the Certificate of Installation prior to completion of the Certificate of Verification, where data checking has indicated that the unit complies, on the condition that a Certificate of Verification will be submitted.
