As a reminder due to legislation enacted in 2020, architecture firms are no longer required to obtain a certificate of authorization. Instead, architecture is practiced through business organization with a licensed architect as the qualifying agent. The qualifier’s license number will now be displayed on letterhead and advertisements where the certificate of authorization, or AA number, once was. The qualifier’s number does not need to be displayed on business cards. However, the qualifier’s number will also appear in the title block on architectural drawings in place of the firm license number.
