5537 and 6737.1 of California Business and Professions Code
The designer is responsible for the overall building design. The designer specifies the building features that determine compliance with the Energy Standards and other applicable building codes. The designer is required to ‘sign the certificate of compliance (CF1R) to certify that the building complies with the Energy Standards.
The designer may personally prepare the documents, or may delegate preparation of the energy analysis and certificate of compliance documents to an energy documentation author or energy consultant. If preparation of the compliance documentation is delegated, the designer must remain in charge of the building design specifications, energy calculations, and all building feature information represented on the certificate of compliance. The designer's signature on the certificate of compliance affirms his or her responsibility for the information submitted.
The designer may be an architect, engineer or other California-licensed professional; however, a licensed design professional may not always be required for low-rise residential buildings. The California Business and Professions Code allows unlicensed designers to prepare design documentation for wood-framed single-family residential building if the dwellings are no more than two stories high, not counting a possible basement. Two-story, wood-framed multifamily buildings may also be designed by unlicensed designers if the building has four or fewer dwelling units. For homes that do not require a licensed design professional, the builder may sign the CF1R in the “Responsible Building Designer’s” signature block.
When the designer is a licensed professional, the signature block on the certificate must include the designer’s license number. When registration is required, the certificate of compliance must be submitted to an approved HERS Provider data registry. All submittals to the registry must be made electronically.
The person who designs the building may delegate the energy analysis and preparation of the certificate documentation to a building energy consultant or documentation author. A completed Certificate of Compliance must be submitted to the enforcement agency during the building permit phase. The certificate demonstrates to the enforcement agency plan checker that the building design complies with the Energy Standards. The information submitted on the certificate must be consistent with the building design features in the plans and specifications for the building submitted to the enforcement agency.
The documentation author is not subject to the same limitations and restrictions of the Business and Professions Code as is the building designer because the documentation author is not responsible for specification of the building design features. The documentation author may provide the building designer with recommendations for building energy features. If building designer approves the recommendations, the features must be incorporated into the design plans and specification documents submitted to the enforcement agency at plan check. The documentation author’s signature on the certificate of compliance certifies that the documentation is accurate and complete, but does not indicate documentation author responsibility for the specification of the features that define the building design. The documentation author provides completed certificate of compliance documents to the building designer who must sign the certificate before submitting to the enforcement agency at plan check.
If registration of the certificate of compliance is required, it must be submitted to the registry and signed electronically by both the designer and documentation author before submitting to the enforcement agency. When document registration is required, only registered certificates of compliance that display the registration number assigned to the certificate by an approved HERS registry are acceptable for submittal to the enforcement agency at plan check.
A list of recommended documentation authors is at the California Association of Building Energy Consultants’ (CABEC) website at: http://ww.cabec.org
Chapter 9 of the Business and Professions Code specifies that for that chapter, the term “contractor” is synonymous with the term “builder.” This 'manual uses “builder” to refer to the general contractor responsible for construction. For production homes, the builder may also be the developer with responsibility for arranging financing, acquiring the land, subdividing the property, securing the necessary land planning approvals, and attending to the other necessary tasks that are required before actual construction. Many production builders are involved in marketing and sales of homes after they are constructed.
During the construction ‘process, the builder or general contractor usually hires specialty subcontractors to provide specific services, such as installing insulation, designing and installing HVAC systems, installing windows and skylights, installing water heating systems, and other services. For homes that do not require a licensed design professional, the builder may sign the CF1R in the “Responsible Building Designer's” signature block.
The builder or general contractor must ensure that certificate(s) of installation (CF2R) are submitted to the enforcement agency by the person(s) responsible for the construction/installation of regulated features, materials, components, or manufactured devices. The builder or general contractor may sign the certificate of installation on behalf of the specialty subcontractors they hire, but the preparation and signature responsibility resides with the specialty subcontractor who provided the installation services. The certificate of installation identifies the installed features, materials, components, or manufactured devices detailed in the plans and specifications, and the certificate(s) of compliance approved by the local enforcement agency. If the installation requires field verification and diagnostic testing by a HERS Rater, the certificate of installation must report the results of the installer's testing of the regulated installations to measure performance. The certificate and the CF2R shall be submitted to an approved HERS registry. A copy of the registered certificate of installation is required to be posted at the building site for review by the enforcement agency in conjunction with requests for final inspection.
When the Energy Standards require registration of the compliance documents, the builder or general contractor must ensure the transmittal/submittal of the required information to an approved HERS registry. The builder or general contractor must arrange for the services of a certified HERS Rater if the certificate of compliance indicates that third-party field verification and diagnostic testing by a rater is required. The builder or general contractor must ensure that a copy of the certificate that was approved by the designer/owner and submitted to the enforcement agency during the permitting phase is transmitted to the registry. The certificate should be made available to the rater who will perform any required field verification and diagnostic testing.
When installation work is complete, the builder or general contractor must ensure that the persons responsible for the installation have transmitted/submitted the required certificate of installation information to the registry. The builder must ensure that the HERS Rater receives a copy of the completed certificate of installation or provide access to the registry that has been registered and signed by the builder or subcontractors responsible for the installation. When registration of the certificate of installation is required, the completed and signed copies that are posted at the building site for review by the enforcement agency, in conjunction with requests for final inspection, are required to be registered copies.
At final inspection, the builder or general contractor is required to leave in the building all applicable completed, signed, dated, and registered (when applicable) compliance documents for the building owner at occupancy. Such information must, at a minimum, include information indicated on the following forms: certificate of compliance (CF1R); certificate(s) of installation (CF2R); and for buildings for which compliance requires HERS field verification, certificate(s) of verification (CF3R). These forms must be in paper or electronic format and must conform to the applicable requirements of §10-103(a).
Specialty subcontractors provide the builder with services from specific building construction trades for installation of features such as wall and ceiling insulation, windows, HVAC systems and/or duct systems, water heating systems, and plumbing systems, and these subcontractors may perform other trade-specific specialty services during building construction. The builder is responsible for all aspects of building construction and has the authority to complete and ‘sign/certify all sections of the required certificate(s) of installation (CF2R) forms. The licensed specialty subcontractor, however, should be expected to complete and sign/certify all applicable certificate(s) of installation that document the completion of the work they have performed. The subcontractor's responsibility for documentation should include providing a registered (when applicable) and signed copy of all applicable CF2Rs to the builder, and posting a registered (when applicable) and signed copy of all applicable CF2Rs at the building site for review by the enforcement agency. The subcontractorS should make the registered and signed copies of the applicable installation forms available to the HERS Rater if third-party field verification is required for compliance, as specified on the CF1R.
When the Energy Standards require document registration, all copies of the certificate(s) of installation submitted to the builder, the enforcement agency, and the HERS Rater are required to be registered copies prepared by following the procedures in Reference Residential Appendix RA2, Reference Joint Appendix JA7, and Section 2.3 of this 'manual.
The enforcement agency is the local agency with responsibility and authority to issue building permits and verify compliance with applicable codes and standards. The agency performs several key roles in the compliance and enforcement ‘process.
2.4.5.1 Plan Check:
The enforcement agency performs plan check review of the certificate(s) of compliance documentation and of the plans and specifications that define the building design submitted to the enforcement agency at the building permit phase. During plan check, the agency compares certificate of compliance documentation to the plans and specifications for the building design to confirm that the building features are specified consistently in all the submitted documents. If the specification for design features on the certificate of compliance does not conform to the specifications on the designer's submitted plans and specifications for the building, the designer must revise the submitted documents to make the design specification consistent in all documents.
If the certificate of compliance indicates the building complies, and they are consistent with the features on the plans and specifications for the building design, then the plan check process can confirm that the design complies with the building energy code. If the enforcement agency determines that the building design complies with the Energy Standards, in 'addition to all the other building codes, it may issue a building permit. When the Energy Standards require document registration, the certificate of compliance documentation submitted for a plan check must be a registered document from an approved registry The one exception is the CF1R-ALT-02-E for HVAC changeouts. If approved by the enforcement agency, permit applicants may use unregistered CF1R-ALT-03-E or CF1R-ALT-04-E documents (dependent upon climate zone) to apply for permits and present the registered CF1R-ALT-02-E to the inspector at the time of the final permit.
2.4.5.2 Construction Inspection:
During building construction, the enforcement agency should make several visits to the construction site to verify that the building is being constructed in accordance with the approved plans and specifications, and energy compliance documentation. At each site visit, the agency should review any applicable certificate(s) of installation that have been posted or made available with the building permit(s). The enforcement agency should confirm that the energy efficiency features installed in the house are consistent with the requirements given in the plans and specifications for the building approved during plan check; that the installed features are described accurately on the certificate(s) of installation; and that all applicable sections of the certificate(s) of installation have been signed by the responsible licensed person(s). The enforcement agency shall not approve a dwelling unit until it has received all applicable certificate(s). When the Energy Standards require registration of the energy compliance documents, the certificate(s) of installation documents must be registered with an approved registry.
2.4.5.3 Corroboration of Field Verification and Diagnostic Testing Procedures:
As described in Reference Residential Appendix Section RA2.4.4, at its discretion, the enforcement agency may require that field verification and diagnostic testing performed by the builder or subcontractors or the certified HERS Rater must be scheduled to be performed at a time when the enforcement agency's field inspector can observe the verification or test procedures to corroborate the results reported/documented on the certificate(s) of installation (CF2R) and/or the certificate(s) of verification (CF3R).
2.4.5.4 Sampling Within Enforcement Agency Jurisdictions:
When sampling is used for HERS verification compliance for newly constructed buildings, all dwellings in a designated sample group must be located within the same enforcement agency jurisdiction and subdivision or multifamily housing development, as specified in Reference Residential Appendix Section RA2.6.3.1
When sampling is used for HERS verification compliance for alterations, the dwellings in a designated sample group are not required to be located within the same enforcement agency jurisdiction. The building owner may choose for the field verification and diagnostic testing to be completed as part of a designated sample group composed of dwelling units for which the same installing company has completed the work that requires field verification and diagnostic testing for compliance, as specified in Reference Residential Appendix Section RA2.8. However, to enable the enforcement agency to schedule testing to accomplish the corroboration described in the previous section, it may choose to require that a separate dwelling unit from the sample group that is located within the respective jurisdiction be tested.
2.4.5.5 Final Approval:
The enforcement agency may approve the dwelling at the final inspection phase if the agency field inspector determines that the dwelling conforms to the requirements of the plans and specifications of the building and certificate of compliance documents approved by the enforcement agency at plan check, and meets all other applicable codes and standards requirements. For dwelling units that have used an energy efficiency compliance feature that requires certificate of installation documentation, the enforcement agency shall not approve the dwelling unit until the agency has received a certificate meeting the §10-103(a) requirements that has been completed, signed, and registered (when applicable) by the builder or subcontractor.
For dwelling units requiring third party HERS field verification and diagnostic testing for compliance, the enforcement agency shall not approve the dwelling unit until the agency has received a registered copy of the certificate of verification that meets the requirements of §10-103(a) and has been signed and dated by the HERS Rater. The builder must ensure that all such required energy compliance documentation has been completed properly and posted at the job site or submitted to the enforcement agency in conjunction with any of the agency's required inspections. However, the agency, in accordance with §10-103(d), as a prerequisite to approval of the building, must examine all required copies of certificate(s) of installation (CF2R) documentation and certificate(s) of verification (CF3R) documentation posted at the site or made available with the building permits for the required inspections. This confirms that they have been properly prepared and are consistent with the plans and specifications and the certificate of compliance documentation approved by the enforcement agency for the building at plan check.
When an alteration has been performed by a participating Third Party Quality Control Program (TPQCP) contractor (see Section 2.4.8 of this 'manual), the enforcement agency may conditionally approve the building based on the certificate of installation (CF2R) if the TPQCP data checking has indicated that the installation complies. However, if subsequent HERS compliance verification procedures determine that resampling, full testing, or corrective action is necessary for such conditionally approved dwellings in the group, the corrective work must be completed. Additional information is in Reference Residential Appendix RA2.4.3, RA2.7, and RA2.8.
2.4.5.6 Corroboration of Information Provided for the Owner/Occupant:
At final inspection, the enforcement agency shall require the builder to leave in the building (for the building owner at occupancy) energy compliance, operating, maintenance, and ventilation information documentation as specified by §10-103(b).
Compliance documents for the building shall, at a minimum, include information indicated on forms: certificate of compliance (CF1R), certificate(s) of installation (CF2R), and, for buildings for which compliance requires HERS field verification, certificate(s) of verification (CF3R). These forms shall be copies of the documentation submitted to or approved by the enforcement agency, and the copies must conform to the applicable requirements of §10-103(a).
Operating information shall include instructions on how to operate or maintain the buildings energy features, materials, ‘components, and mechanical devices correctly and efficiently. Such information shall be in a folder or 'manual that provides all information in §10-103(b). This operating information shall be in paper or electronic format. For dwelling units, buildings or tenant spaces that are not individually owned and operated, or are centrally operated, such information shall be provided to the person(s) responsible for operating the feature, material, ‘component, or mechanical device installed in the building. This information shall be in paper or electronic format.
Maintenance information shall be provided for all features, materials, components, and manufactured devices that require routine maintenance for efficient operation. Required routine maintenance actions shall be clearly stated and incorporated on a readily accessible label. The label may be limited to identifying, by title and/or publication number, the operation and maintenance 'manual for that particular model and type of feature, material, component, or manufactured device. For dwelling units, buildings or tenant spaces that are not individually owned and operated, or are centrally operated, such information shall be provided to the person(s) responsible for maintaining the feature, material, component, or mechanical device installed in the building. This information shall be in paper or electronic format.
Ventilation information shall include a description of the quantities of outdoor air that the ventilation system(s) are designed to provide to the conditioned space of the building, and instructions for proper operation and maintenance of the system. For buildings or tenant spaces that are not individually owned and operated, or are centrally operated, such information shall be provided to the person(s) responsible for operating and maintaining the feature, material, component, or mechanical ventilation device installed in the building. This information shall be in paper or electronic format.

Question
We are an enforcement agency with jurisdiction over the replacement of the outdoor compressor/condenser unit of an HVAC unit (an alteration), and the HVAC contractor who pulled the permit for replacing the unit has requested that we approve the final inspection and close out the permit based only on the certificate of installation (CF2R) for this job. This job requires HERS verification, and I thought it was necessary to receive the HERS Rater's completed and signed certificate of verification (CF3R) before the job could comply as a condition to final approval of the installation. Is there an allowance for compliance based only on the CF2R?
Answer
Yes. The enforcement agency may provide a "conditional" final approval of the installation based upon the CF2R for alterations jobs only, and only if the installing contractor is an approved Third Party Quality Control Program (TPQCP) installing contractor. The conditional final approval is allowed if TPQCP data checking has scrutinized the diagnostic test data submitted by the approved contractor's diagnostic test for the installation, and such data checking indicates the installation complies as shown on the CF2R.
The permittee is still required to complete all HERS verification procedures and comply with all HERS verification criteria. A CF3R is still required to be submitted to the enforcement agency, builder, and homeowner for the documentation procedure to be complete. If HERS verification of the approved TPQCP contractor's installation work determines that resampling, full testing, or corrective action is necessary to bring the installation into compliance, such work must be completed before issuing the CF3R. Sampling procedures for HERS verification for installation work performed by an approved TPQCP contractor allows for testing of one sample from a designated group of up to 30 dwellings/installations for which the work was performed by the same approved TPQCP installing contactor. Refer to Reference Residential Appendix Sections RA2.4.3, RA2.7 and RA2.8 (and Chapter 9 of this 'manual) for additional information.
A HERS Provider is an organization that the Energy Commission has approved to administer a HERS program. The provider certifies and trains raters and maintain quality control over the activities performed by HERS Raters who provide third-party field verification and diagnostic testing on installed energy efficiency features in dwellings when required for compliance with the Energy Standards. Visit the Energy Commission website for the list of approved HERS Providers.
The HERS Provider must maintain a database (data registry) that incorporates a website-based user interface that accommodates the needs of the authorized users of the data registry who administer HERS compliance, document registration, and Energy Standards enforcement. The data registry must receive and record information that can adequately identify and track measures that require HERS verification in a specific dwelling, and must have the capability to determine compliance based on the information input from the results of applicable testing or verification procedures reported as input to the data registry for the dwelling. When the requirements for compliance are met, the registry must make available a unique registered certificate for use in complying with document submittal requirements to enforcement agencies, builders, building owners, HERS Raters, and other interested parties. The registry must simplify electronic submittal of the registered certificates to an Energy Commission document repository for retention of the certificates for use in regulations enforcement.
The HERS Provider must make available via phone or Internet communications interface a way for building officials, builders, raters, and other authorized users of the registry to verify the information displayed on copies of the submitted compliance documentation. Refer to Reference Residential Appendices Section RA2.4.2 and Reference Joint Appendix JA7 for additional information.
The HERS Rater is trained and certified by an Energy Commission-approved HERS Provider to perform the field verification and diagnostic testing that may be required to demonstrate and document compliance with the Energy Standards. Raters receive special training in diagnostic techniques and building science as part of the certification administered by the HERS Providers. Therefore, HERS Raters are considered special inspectors by enforcement agencies and shall demonstrate competence, to the satisfaction of the agency, to conduct the required visual inspections and diagnostic testing of the regulated energy efficiency features installed in the dwelling.
HERS Raters should recognize that some enforcement agencies charge a fee for special inspectors in their jurisdictions. Because they are special inspectors for the enforcement agency, a rater may be disciplined (for example, prohibit a HERS Rater from conducting field verifications/testing in a local jurisdiction) if the agency determines that a rater does not comply with the Energy Standards. Raters may also be required to attain business licenses in some jurisdictions.
If the documentation author who produced the certificate of compliance documentation for the dwelling is not an employee of the builder or subcontractor, the documentation author for the dwelling may also perform the responsibilities of a HERS Rater, provided the documentation author has met the requirements and has been certified, and is associated with an Energy Commission-approved HERS Providers.
If requested to do so by the builder or subcontractor, the rater may help the builder or subcontractor transmit/submit the certificate(s) of installation (CF2R) information to the provider for registration. However, the HERS Rater may not certify the information on a certificate of installation. The builder or subcontractor responsible for the installation must provide the certification/signature to confirm the information submitted to the registry, even if the rater transmitted the data. Refer to Reference Residential Appendix Section RA2.5 and Reference Joint Appendix JA7 for more information.
The HERS Rater conducts the field verification and diagnostic testing of the installed special features when required by the certificate of compliance. The rater must transmit the results of the field verification and diagnostic testing to the HERS registry. The rater must provide to the registry all information required to complete the certificate(s) of verification form and must submit a certification/signature to the registry. The data registry will make available registered copies of the certificate(s) of verification to the rater, the builder, the enforcement agency, and other authorized users of the registry. Printed copies, electronic or scanned copies, and photocopies of the completed, signed, and registered certificate(s) of verification (CF3R) are allowed for document submittals, subject to verification that the information contained on the copy conforms to the registered document information on file in the HERS registry for the dwelling. A completed, signed, and registered copy of the CF3R must be posted at the building site or made available to the inspector for review by the enforcement agency in conjunction with requests for final inspection for each dwelling unit.
Go to to Reference Residential Appendix Section RA2.4.2 for more information
Example 2-6
Question
Can a certified HERS Rater who does the field verification and completes and signs the CF3R for a dwelling also perform the testing required of the builder or installer to certify compliance with the Title 24, Part 6 installation requirements on the CF2R?
Answer
Yes. This approach is allowed when the HERS Rater is doing field verification for every dwelling (100 percent testing), but it is not allowed when the rater performs verification using a designated sample group of dwellings. When 100 percent testing is used for HERS verification, the builder or the installer may use the information from the rater's verification or diagnostic test results when completing the CF2R. When doing so, builders or installers signing the certification statement on the CF2R are assuming responsibility for the information in the form, and are certifying that the installation conforms to all applicable codes and regulations. The rater may not ‘sign the form and cannot be assigned the responsibilities of the builder or installer, as stated on the CF2R form and in regulations.
If the HERS Rater determines that the compliance requirements are not met, the HERS Rater will submit the data of the failed verification/testing into a HERS registry for retention. The builder or installer must make the needed corrections. Once corrections have been made and the rater determines that all compliance requirements are met, the builder or installer may certify the work by completing and signing the applicable section of the CF2R. The HERS Rater can complete the CF3R documentation for the dwelling.
Example 2-7
Question
I heard that there are conflict-of-interest requirements that HERS Raters must abide by when doing field verification and diagnostic testing. What are these requirements?
Answer
Raters are expected to be objective, independent, third parties as field verifiers and diagnostic testers. They are special inspectors for local enforcement agencies. By law, raters must be independent entities from the builder or subcontractor installer of the energy efficiency features being tested and verified. They can have no financial interest in the installation of the improvements. Raters cannot be employees of the builder or subcontractor whose work they are verifying. Also, they cannot have a financial interest in the builder’s or contractor’s business, or advocate or recommend the use of any product or service that they are verifying.
The Energy Commission expects HERS Raters to enter into a contract with the builder (not with subcontractors) to provide independent, third-party diagnostic testing and field verification. The procedures adopted by the Energy Commission call for direct reporting of results to the builder, the HERS Provider, and the building official. Although not recommended by the Energy Commission, a three-party contract among builder, rater and subcontractor is possible, provided that the contract delineates the independent responsibilities of the rater and the responsibilities of a subcontractor to take corrective action in response to deficiencies found by a rater. Such contracts may also establish the role for a subcontractor to serve as administrator for the contract, including scheduling the rater, invoicing, and payment, provided the contract ensures that money paid by the builder to rater can be traced through audit. It is critical that such contractors preserve the rater's independence in carrying out the responsibilities specified in Energy Commission-adopted HERS field verification and diagnostic testing procedures. Even though such contracts do not violate the requirements of the Energy Commission, the closer that the working relationship is between the rater and the subcontractor whose work is being inspected, the greater the potential for compromising the rater’s independence.
Compliance cannot be shown using sampling if a "three-party contract" is used. One hundred percent of homes must be tested by a HERS Rater when a three-party contract is used. Raters must use their own diagnostic equipment (and not the installing contractor's equipment) when verifying work performed when a three-party contract is used.
(See Blueprint #66, pp. 1-2, and Blueprint #67, p. 7.)
HERS Providers must provide ongoing monitoring of the propriety and accuracy of raters in the performance of their duties and to respond to complaints about the rater’s performance. Where there may be real or perceived compromising of the rater’s independence, the provider is responsible for increasing scrutiny of the rater, and take action to ensure objective, accurate reporting of diagnostic testing and field verification results, in compliance with Energy Commission adopted procedures.
Enforcement agencies have authority to require raters to demonstrate their competence to the satisfaction of the building official. When the rater’s independence is in question, building officials can prohibit a particular rater from being used in their jurisdiction, or disallow practices that the building official believes will compromise the rater's independence. Building officials may require the use of a three-party contract. For additional information please contact the Energy Commission Hotline.
The Energy Commission may approve Third-party Quality Control Programs (TPQCP) that serve some of the functions of HERS Raters for field verification but do not have the authority to ‘sign compliance documentation as a rater. The programs do the following:
A. Train installers, participating program installing contractors, installing technicians, and specialty third-party quality control program subcontractors about compliance requirements for measures for which diagnostic testing and field verification is required.
B. Collect data from participating installers for each installation completed for compliance credit.
C. Perform data checking analysis of information from diagnostic testing performed on participating TPQCP contractor installation work to evaluate the validity and accuracy of the data and to independently determine whether compliance has been achieved.
D. Provide direction to the installer to retest and correct problems when data checking determines that compliance has not been achieved.
E. Require resubmission of data when retesting and correction is directed.
F. Maintain a database of all data submitted by the participating TPQCP contractor in a format that is acceptable and made available to the Energy Commission upon request.
The HERS Provider must arrange for an independent rater to conduct independent field verifications of the installation work performed by the participating TPQCP contractor and third party quality control program. If group sampling is used for HERS verification compliance for jobs completed by a participating TPQCP contractor, the sample from the group that is tested for compliance by the rater may be selected from a group composed of up to 30 dwellings for which the same participating contractor has performed the installation. For alterations, the installation work performed by TPQCP contractors may be approved at the enforcement agency's discretion, based upon a properly completed certificate of installation (CF2R) as described in Section 2.4.5, on the condition that if subsequent HERS compliance verification procedures determine that resampling, full testing or corrective action is necessary for such conditionally approved dwellings in the group, the corrective work must be completed. If the standards require registration of the certificate of installation, the certificate must be a registered copy from a data registry.
Refer to Reference Residential Appendix RA2.4.3, RA2.7, and RA2.8 for additional information.
Building owner means the owner of the dwelling unit. For production homes, the owner is the person or family that the builder sells the house to. In custom homes and remodels, the owner may be the builder or developer, a general contractor, architect, or engineer.
As part of the compliance ‘process, the owner must receive compliance, operating, maintenance, and ventilation information documents at the time of occupancy. The enforcement agency must require the builder to leave this information in the building for the building owner at occupancy as specified in §10-103(b).
Example 2-8
Question
What is my responsibility with respect to the CF2R (certificate of installation) as: (a) an enforcement agency inspector; and (b) as a builder?
Answer
(a)The enforcement agency’s field inspector verifies that the required CF2R form(s) are filled out completely and in conformance with the requirements of §10-103(d) during applicable site inspections, which includes verifying the CF2R is registered when required by the standards, and confirming that the person responsible for the installation has signed the certificate. Inspectors must verify that the installed features conform to the plans and specifications and the certificate of compliance approved by the enforcement agency.
The CF2R is required to be posted at the job site or kept with the building permit, and must be made available for all applicable inspections. The inspector should verify certificate(s) of installation during the applicable site inspections (for example, verifying the certificates of installation for quality insulation installation, QII, at the framing and insulation inspections). Do not wait until the final inspection to check all CF2R documentation.
(b)The general contractor or his/her agent (for example, the installing contractor) must complete and sign the CF2R form for the work performed. A homeowner acting as the general contractor for a project is authorized to sign the CF2R. The installing contractor should provide the certification since the CF2R certification statement is an installer’s assurance to the owner that the work has been completed properly and complies with applicable codes and regulations. The CF2R certification statement and signature indicates that the equipment or feature: 1) was installed properly and it confirms that the information provided on the form properly identifies the installed building component or equipment; 2) is equivalent or more efficient than required by the approved plans (as indicated on the CF1R); and 3) meets all relevant certification or performance requirements.
Refer to §10-103(a)3 for more information about certificate of installation requirements.
