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 Code 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 Code.
The designer may personally prepare the documents or 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 single-family residential buildings. The California Business and Professions Code allows unlicensed designers to prepare design documentation for wood-framed single-family residential buildings if the dwellings are no more than two stories high, not counting a possible basement. For homes that do not require a licensed design professional, the builder may sign the CF1R in the “Responsible Building Designer” 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 data registry. All submittals to the registry must be made electronically.
a. §10-103(a)1C
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 CF1R must be submitted to the enforcement agency during the building permit phase. The certificate demonstrates to the enforcement agency plan examiner that the building design complies with the Energy Code. The information submitted on the CF1R 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 it to the enforcement agency at plan check.
If registration of the CF1R 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), CABEC Homepage (https://cabec.org/).
Chapter 9 of the Business and Professions Code specifies the term “contractor” is synonymous with the term “builder.” This manual uses “builder” to refer to the general contractor responsible for construction. For additions and alterations to existing homes, the contractor can act as the builder or general contractor (typically for smaller projects). For production homes, the builder may also be the developer responsible 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 construction, 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 others. 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 CF2Rs 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 CF2R on behalf of the specialty subcontractors they hire, but the preparation and signature responsibility reside with the specialty subcontractor who provided the installation services. The CF2R identifies the installed features, materials, components, or manufactured devices detailed in the plans and specifications, and the CF1R approved by the enforcement agency. If the installation requires HERS verification, the CF2R must report the results of the installer's testing of the regulated installations to measure performance. The CF1R and the CF2R shall be submitted to an approved HERS registry. A copy of the registered CF2R is required to be posted at the building site for review by the enforcement agency in conjunction with requests for intermediate and final inspections.
When the Energy Code requires 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 CF1R indicates that HERS verification is required. The builder or general contractor must ensure that a copy of the CF1R that was approved by the designer/owner and submitted to the enforcement agency during the permitting phase is transmitted to the HERS registry. The CF1R should be made available to the HERS Rater, who will perform any required HERS testing.
When installation is complete, the builder or general contractor must ensure that the persons responsible for the installation have transmitted/submitted the required CF2R information to the registry. The builder must ensure that the HERS Rater receives a copy of the completed CF2R or provide access to the HERS registry that has been registered and signed by the builder or subcontractors responsible for the installation. When registration of the CF2R 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 (CF1R, CF2R, and CF3R if applicable) for the building owner at occupancy. 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, fenestration, HVAC and air distribution, or water heating and plumbing. 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 CF2Rs. The licensed specialty subcontractor, however, should be expected to complete and sign/certify all applicable CF2Rs 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 CF2R at the building site for review by the enforcement agency. The subcontractors should make the registered and signed copies of the applicable CF2Rs available to the HERS Rater if HERS verification is required for compliance, as specified on the CF1R or any CF2R.
When the Energy Code requires document registration, all copies of the CF2Rs 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 authority having jurisdiction (AHJ) to issue building permits and verify compliance with applicable codes and standards (including the Energy Code). The agency performs several key roles in compliance and enforcement.
The enforcement agency performs plan check review of the CF1R and the plans and specifications that define the building design submitted to the enforcement agency at the building permit phase. During the plan check, the agency compares CF1R 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 CF1R 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 CF1R indicates the building complies, and it is consistent with the features on the plans and specifications for the building design, then the plan check can confirm that the design complies with the Energy Code. If the enforcement agency determines that the building design complies with the Energy Code, in addition to all the other applicable codes and standards, it may issue a building permit. When the Energy Code requires document registration, the CF1R submitted for a plan check must be a registered document from an approved HERS 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.
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, specifications, and CF1R. At each site visit, the agency should review any applicable CF2Rs 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 CF1R for the building approved during plan check, that the installed features are described accurately on the CF2R, and that all applicable sections of the CF2R have been signed by the responsible licensed person(s). The enforcement agency should not approve a dwelling unit until it has received the applicable certificate(s). When the Energy Code requires registration of the energy compliance documents, the CF2R must be registered with an approved HERS registry.
As described in Reference Residential Appendix Section RA2.4.4, at its discretion, the enforcement agency may require that HERS verification by the builder or subcontractors or the HERS Rater be scheduled so that the enforcement agency's field inspector can observe the HERS verification procedures to corroborate the results reported on the CF2R and CF3R.
When sampling is used for HERS testing for newly constructed buildings, all dwellings in a designated sample group must be located within the same enforcement agency jurisdiction and subdivision as specified in Reference Residential Appendix Section RA2.6.3.1
When sampling is used for HERS testing for alterations, the dwellings in a designated sample group are not required to be located within the same enforcement agency jurisdiction. They are required to have the same installing contractor and must be assigned to the same rater. The building owner may choose for the HERS verification 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 HERS testing, 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.
The enforcement agency may approve the dwelling at the final inspection phase if all field inspections have determined all of the following:
•The dwelling conforms to the requirements of the plans and specifications as approved by the enforcement agency.
•The dwelling conforms with the CF1R approved by the enforcement agency.
•The dwelling conforms with all other applicable codes and standards requirements.
•The enforcement agency is in receipt of all CF2R required by the Energy Code and as identified by the CF1R for the dwelling unit.
•The CF1R and CF2R are signed and registered (when applicable) by the builder or subcontractor.
•For dwelling units requiring HERS testing, the enforcement agency has received a copy of the CF3R as registered with a HERS register
•The CF3R 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 the required inspections. However, the enforcement agency, in accordance with §10-103(d), as a prerequisite to approval of the building, must examine all required copies of the CF1R, CF2R, and CF3R posted at the site or made available with the building permits for the required inspections. This examination confirms that these compliance documents have been properly prepared and are consistent with the plans and specifications approved by the enforcement agency.
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 CF2Rs if the TPQCP data checking has indicated that the installation complies. However, if subsequent HERS testing determines that resampling, full testing, or corrective action is necessary for such conditionally approved dwellings in the group, the corrective work must be completed and tested. Additional information is in Reference Residential Appendix RA2.4.3, RA2.7, and RA2.8.
At final inspection, the enforcement agency shall require the builder to leave in the building (for the building owner at occupancy) Energy Code compliance documents, operating and maintenance manuals, and ventilation information, as specified by §10-103(b).
Compliance documents for the building shall include all valid certificates of compliance (CF1R), certificate of installation (CF2R), and certificate of verification (CF3R). These documents must conform to the applicable requirements of §10-103(a).
Operating information shall include instructions on how to operate or maintain the energy features, materials, components, and mechanical devices of the building correctly and efficiently. Such information shall be in a folder or otherwise bound to provide 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 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 testing of one sample from a designated group of up to 30 dwellings 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 CEC has approved to administer a HERS program. The provider certifies, trains, and oversees HERS Raters. HERS Raters provide HERS verification on installed energy efficiency features in dwellings when required for compliance with the Energy Code. Visit the CEC website for the list of approved HERS providers at http://www.energy.ca.gov/HERS/
The HERS provider must also maintain a HERS 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. The HERS registry must receive, and record information required by HERS testing in a specific dwelling. The HERS registry must have the capability to verify that the recorded information complies with the XML schema developed by the CEC. When the input data are verified, the HERS registry must make available a unique registered certificate available to authorized users. These registered certificates (CF1R, CF2R, and CF3R) are used in complying with document submittal requirements to local enforcement agencies, builders, building owners, HERS Raters, and other interested parties. The HERS registry helps simplify electronic submittal of the registered certificates to an CEC 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 authorized users of the registry to verify the information displayed on copies of registered documents. 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 a CEC-approved HERS provider to perform the HERS verification that may be required to demonstrate and document compliance with the Energy Code. HERS Raters receive special training in diagnostic techniques and building science as part of the certification administered by the HERS providers. The HERS Raters operate independently from the HERS providers and are to act as independent, third-party agents to the project contractor installing the energy efficiency requirements for the construction project. HERS Raters shall be considered “special inspectors” by enforcement agencies, which is not to be confused with the same term used by local enforcement agencies regarding inspectors with specific ICC training and certification. HERS Raters are not special inspectors for the local enforcement agencies; they are special inspectors for the project proponents, including the installing contractor. HERS Raters may be required to attain business licenses in some jurisdictions.
The CEC has determined that a HERS Rater may act as a document author for the CF2R for a residential project with no violation of the provisions of “Conflict of Interest” (Title 20, Section 1673[j]). If requested to do so by the builder or subcontractor, the HERS Rater may aid the builder or subcontractor register the CF2R with a HERS registry. However, the HERS Rater may not certify the information on a CF1R as the responsible person (that is, sign the CF1R as if they were the builder or subcontractor).
The builder or subcontractor responsible for the installation must provide the certification by electronic signature to confirm the information submitted to the registry. Refer to Reference Residential Appendix Section RA2.5 and Reference Joint Appendix JA7 for more information. The HERS Rater may not certify the information on a CF2R as the responsible person, unless the rater and installer have signed a written agreement that the Rater is an authorized representative that may sign on behalf of the installer. The installing contractor remains the responsible person. Qualifications for delegation of signature authority are detailed in §10-103(a)3A.
The HERS Rater conducts the HERS verification of the installed energy efficiency features when required by the CF1R or CF2R. The HERS Rater must transmit the results of the HERS verification to the HERS registry. The HERS Rater must provide to the registry all information required to complete the CF3R and must certify those data as accurate and complete to the registry. The registry will make available registered copies of the CF3R to authorized users. Printed copies, electronic or scanned copies, and photocopies of the completed, signed, and registered 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 registry for the dwelling. A copy of the registered 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 Reference Residential Appendix Section RA2.4.2 for more information.
Example 2-6
Question
Can a certified HERS Rater who performs and registers the HERS testing for a dwelling also perform the HERS verification 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 HERS verification for every dwelling (100 percent testing), but it is not allowed when the HERS 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 HERS Rater’s HERS 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 HERS Rater may sign using the installer’s delegated signature authority but cannot be assigned the responsibilities of the builder or installer, as stated on the CF2R and as prescribed by the Energy Code. Refer to §10-103(a)3A for authorized representation.
If the HERS Rater determines that the compliance requirements are not met (in other words, the HERS verification results in a failure), the HERS Rater will submit the data of the failed HERS testing into a HERS registry for retention. The builder or installer must make the needed corrections. Once corrections have been made and the HERS 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 HERS verification. What are these requirements?
Answer
Raters are expected to be objective, independent third parties as field verifiers and diagnostic testers. By law, raters must be independent 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 CEC expects HERS Raters to enter into a contract with the builder (not with subcontractors) to provide independent, third-party HERS verification. The procedures adopted by the CEC call for direct reporting of results to the HERS registry where the project has been established by the builder. Although not recommended by the CEC, a three-party contract among builder, rater, and subcontractor is possible, provided that the contract delineates the independent responsibilities of the HERS Rater and the responsibilities of a subcontractor to take corrective action in response to deficiencies found by a HERS Rater. Such contracts may also establish the role for a subcontractor to serve as administrator for the contract, including scheduling the HERS Rater, invoicing, and payment, provided the contract ensures that money paid by the builder to the HERS Rater can be traced through an audit. It is critical that such contractors preserve the HERS Rater's independence in carrying out the responsibilities specified in CEC-adopted HERS testing procedures. Even though such contracts do not violate the conflict of interest requirements, the closer that the working relationship is between the HERS Rater and the subcontractor whose work is being inspected, the greater the potential for compromising the HERS 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. HERS 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.
HERS providers must provide ongoing monitoring of the propriety and accuracy of HERS Raters in the performance of their duties and to respond to complaints about the HERS Rater’s performance. Where there may be real or perceived compromise of the HERS Rater’s independence, the HERS provider is responsible for increasing scrutiny of the HERS Rater and acts to ensure objective, accurate reporting of HERS testing results in compliance with the Energy Code.
Enforcement agencies have authority to require HERS Raters to demonstrate their competence to the satisfaction of the building official. When the HERS Rater’s independence is in question, building officials can prohibit a particular HERS Rater from being used in their jurisdiction or disallow practices that the building official believes will compromise the HERS Rater's independence. Building officials may require the use of a three-party contract. For additional information please contact the CEC Hotline.
A Third Party Quality Control Program (TPQCP) is a service that verifies the work of participating installers by gathering extensive diagnostic data and flagging potentially noncompliant installations.
The CEC may approve TPQCPs that serve some of the functions of HERS Raters HERS verification but do not have the authority to sign compliance documentation as a HERS Rater. A TPQCP:
A. Trains installers, contractors, technicians, and specialty subcontractors about compliance requirements for features that require field verification and diagnostic testing.
B. Collects more data than would be required to demonstrate compliance with the Energy Code from participating installers for each installation.
C. Performs validation and analysis of information from diagnostic HERS verification performed on a participating contractor’s installation work to evaluate the validity and accuracy of the data and independently determine whether compliance has been achieved.
D. Provides direction to the installer to retest and correct problems when data checking indicates that compliance has not been achieved.
E. Requires submission of data when retesting and correction are directed.
F. Maintains a database of all data submitted by the participating TPQCP contractor in a format that is acceptable and made available to the CEC upon request.
The HERS provider must arrange for an independent HERS Rater to conduct independent HERS verification of the installation performed by the participating TPQCP contractor. If a group sampling is used for HERS verification 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 performed by TPQCP contractors may be approved at the enforcement agency's discretion and on the condition that, if subsequent HERS verification determines that resampling, full testing, or corrective action is necessary for such conditionally approved dwellings in the group, the corrective work must be completed.
Refer to Reference Residential Appendix RA2.4.3, RA2.7, and RA2.8 for additional information.
“Building owner” refers to the owner of the dwelling unit. For production homes, the owner is the builder or the person(s) that buys the new home. In custom homes and remodels, the owner may be the homeowner, builder, 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). This requirement applies to newly constructed homes, additions, and alteration to an existing home. The exact compliance, operational, maintenance, and ventilation documents are based on the scope of the construction project.
Example 2-8
What is my responsibility with respect to the CF2R (certificate of installation) as the enforcement agency inspector?
Answer 1
The field inspector for the enforcement agency has two general responsibilities, according to the Energy Code (§10-103[d]2:
The CF2Rs and CF3Rs (if applicable) are all consistent with the CF1Rs, plans, specifications, and change orders as approved by the enforcement agency. These include all installed features, materials, components, or manufactured devices regulated by the Appliance Efficiency Regulations or the Energy Code as indicated on the CF1Rs.
All required CF2Rs and CF3Rs are completed, signed, and posted or made available with the permit issued for the construction project.
The CF2Rs and CF3Rs (if applicable) are all consistent with the CF1Rs, plans, specifications, and change orders as approved by the enforcement agency. This includes all installed features, materials, components, or manufactured devices regulated by the Appliance Efficiency Regulations or the Energy Code as indicated on the CF1Rs.
All required CF2Rs and CF3Rs are completed, signed, and posted or made available with the permit issued for the construction project.
While the compliance documents (CF1R, CF2R, and CF3R) are required to be submitted to the enforcement agency, the agency is not required to use the compliance documents in any way.
The CEC recommends that the inspector verify CF2R during the applicable site inspections. For example, verify the CF2R for quality insulation installation during the framing, air sealing, and insulation inspections. Do not wait until the final inspection to check all CF2R documentation.
Question 2
What is my responsibility with respect to the CF2R (certificate of installation) as a builder?
Answer 2
The general contractor is responsible for completing and signing 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 CF2R since the 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 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.
