Accredited verifiers with specific experience on large, multifamily NGBS projects.

Find a Multifamily Verifier

NGBS Green Accredited Verifiers are trained to inspect for any certification type. Some verifiers have significant experience with multifamily projects. Builders and developers may find it more cost effective to retain an experienced multifamily verifier outside their local area, than a nearby verifier with less specialized experience. Home Innovation encourages builders, developers, and architects to seek verification proposals from several verifiers to ensure you find the individual best suited to your specific project.

Please contact Home Innovation Labs if we can provide any assistance in locating an accredited verifier.
