DBE Certification

BSD utilizes an on-line application process to receive and review new applications for DBE certification and No Change Affidavits (NCA).

OSD is required to review applications within 90 days. DBE firms whose initial applications were processed by BSD are required to submit every year on the anniversary date of their certification a NCA, the firm’s balance sheet and income statement and a completed and signed copy of their firm’s federal tax return. The NCA affirms that there have been no changes in the firm’s circumstances affecting its ability to meet size, disadvantaged status, ownership, or control.

To start and complete an on-line DBE certification application and provide a No Change Affidavit (for firms already certified as DBE) you must Start by clicking the button below to apply for DBE Certification, submit a No Change Affidavit or Interstate application.
