Third-party NGBS Green Verifiers accredited by Home Innovation Research Labs.

Find a Verifier for NGBS Project Certification

Use the drop-down menu below to get a list of accredited NGBS Green Verifiers who work in your state. Home Innovation Research Labs accredits individuals as NGBS Green Verifiers, not companies; and each verifier is accredited to specific versions of the NGBS. Be sure you are working with the specific verifier listed and that s/he is also accredited to the NGBS version you are using. Home Innovation is not able to certify projects inspected by non-accredited individuals. If your state is not listed, there are currently no local verifiers — contact Home Innovation Labs for more information, and/or to suggest a potential verifier candidate in your area.

Need a verifier with large multifamily project experience? All accredited NGBS Green Verifiers have been trained to complete multifamily verifications to the National Green Building Standard, but some have developed an expertise in verifying large multifamily projects. These individuals are listed separately on this website to ease your search in finding those with this kind of expertise.

What is an NGBS Green Master Verifier? A “MASTER” icon next to a listing indicates an individual has achieved exclusive, top-tier accreditation based on his/her significant green building knowledge and applied experience verifying NGBS Green compliance. We also have a list of all NGBS Green Master Verifiers.
