Building and Floor Security

OSD is located in a state government building on a secure floor.

We recommend that all visitors carry some form of government issued identification, like a state identification card, driver’s license, or passport.

To enter the McCormack building, visitors must pass through a metal detector and have their belongings pass through an x-ray machine. Visitors are subject to secondary searches using hand-held metal detectors.

To enter OSD’s offices, visitors must sign in at the OSD Reception Area in Room 1017. The receptionist will alert the OSD staff member expecting you.

OSD strongly recommends scheduling appointments with specific staff since visitors cannot be allowed onto the floor without an escort.
