Indoor AirPlus Certification Review

The EPA has developed a process, called Certification Review, to address cases where a homeowner has concerns about the Indoor AirPlus certification of their recently purchased home they are not able to resolve with the builder. The purpose of a Certification Review is limited to determining whether a home should maintain its Indoor AirPlus certification.

Homeowners should understand that making this determination is the limit of EPA’s purview in addressing concerns about home certifications.

What is a Home Certification Organization (HCO)?

IAP HCOs are responsible for decisions related to the granting and withdrawal of IAP certifications and provide for the credentialing, oversight, and quality assurance of IAP verifiers. The name of the HCO that conducted oversight of your home’s IAP certification is found in the “Verification Oversight By:” field on the IAP label affixed to the home and on the IAP certificate.

Certification Review Process

Indoor AirPlus (IAP) homeowners may submit an official request for Certification Review directly to the Home Certification Organization (HCO) that originally certified the home.

The HCO will review the request for eligibility and assign an appropriate individual to complete the review according to the HCO’s policies and EPA requirements. The assigned reviewer will complete the review and prepare a Certification Review Report within 60 days of assignment. A copy of the report will be shared with the HCO, which will in turn share the report with the homeowner and EPA. 

  • The homeowner may arrange for destructive testing to inspect items that would otherwise not be visible. For example, if it were suspected that water supply pipes installed in an exterior wall were not insulated, observation holes could be cut or drilled in the interior gypsum board.
    • The homeowner bears complete responsibility for arranging all demolition and repair for destructive testing that they elect to undertake
    • Before undertaking destructive testing, it is recommended that homeowners consult with a qualified expert who can use non-invasive methods like infrared imaging to prioritize areas of concern.
    • Demolition work, such as creating observation holes, must occur in the presence of the assigned reviewer performing the Certification Review
    • Areas that are exposed outside the presence of the assigned reviewer shall be ignored for the purpose of the Certification Review.
  • If the assigned reviewer determines that the home fails the Certification Review, the IAP certification of the home shall be withdrawn and the IAP label will be removed
  • If the assigned reviewer determines that the home passes the Certification Review, the IAP certification of the home shall be maintained. A homeowner will have an opportunity to appeal this determination, at their discretion (please refer to the HCO’s policies for details on the appeals process)

Eligibility

  1. The home must have been Indoor AirPlus Version 2 (or later) certified or sold as such.
  2. The homeowner must have attempted to resolve the complaint with the builder or verification organization.
  3. The home must have been built, purchased, and/or certified within the last two years and be owned by the original owner. For homes older than two years or not owned by the original owner, the Certification Review will be unable to determine whether discrepancies are due to homeowner modifications of the home or natural aging of construction materials.
  4. There must have been no significant structural changes to the home since it was built. If such modifications have been made, the Certification Review will not be able to determine whether those modifications caused any discrepancies with the Indoor AirPlus program requirements.
  5. There must be evidence that the home is not in compliance with one or more applicable Indoor AirPlus program requirements. Homeowners are encouraged to be as specific as possible in identifying the program requirement that they believe was not met and providing evidence, including photos if possible. 

REMINDER: EPA’s role in certification review is limited to determining whether the IAP certification is maintained or withdrawn. The Agency has no authority to pursue (this should not be considered a comprehensive list of such actions):  

  • Sending EPA personnel to inspect a home in question.

  • Acting as an intermediary between parties regarding disputes.

  • Taking legal action to compel a builder to make modifications to a home.

  • Pursuing financial compensation on behalf of the homebuyer.

  • Pursuing criminal enforcement or other penalties against the builder beyond revocation of partnership.

  • Providing legal guidance to homeowners regarding litigation they are taking or may pursue against the builder.
