What is a Project Reference Number or a "Billing Identification" Number?

The "Project Reference Number" (Billing Number) is a set of numbers and/or letters that is (created by the Responsible Party or the Building Management Company) similar to a purchase order number. This is not YOUR JOB NUMBER.

The "Project Reference Number" (Billing Number) is our authorization to bill the Responsible Party and provides them with a reference number on our invoices that can be used to tie the review and inspection charges for the permit to the corresponding project. Typically, the same "Project Reference Number" will be used for the building permit and all related trade permits for the same project.

Please note: If we do not have a Project Reference Number, we cannot set up or issue a permit.

Complete Project Submittals may be made to Permitting Services - 2nd floor - 1900 SW 4th Avenue. (Tuesday - Friday: 8:00 a.m. – 3:00 p.m.)
