A permit runner is an individual who is responsible for physically delivering and picking up building permit applications and related documents from the local building department. They may also be responsible for obtaining any required signatures or approvals from other agencies or professionals. A permit expediter, on the other hand, is a professional who specializes in helping property owners navigate the process of obtaining building permits. They may be hired by property owners or contractors to handle the paperwork and communicate with the building department on their behalf. In addition to delivering and picking up documents, permit expediters may also provide guidance and assistance with completing the necessary paperwork and complying with local codes and regulations. Overall, the main difference between a permit runner and a permit expediter is the scope of their services. Permit runners are primarily responsible for physically delivering and picking up documents, while permit expediters provide a wider range of services to help property owners and contractors obtain building permits.
