Inspectors are required to recertify every two years. Recertification must be completed before the expiration date of your certification. Once your certification expires, you are no longer able to perform inspections. If you do not successfully complete a recertification course within six months following the expiration of your certification, you must successfully complete the full certification course to be reinstated.
