Your building is equipped with an access control system monitored by Kastle Systems. The main entrance doors, located on F Street, are locked from 6:00 PM to 7:00 AM, Monday through Friday and 24 hours on weekends and holidays. Your employees may gain access to the building during security hours with their Kastle cards.

Kastle Cards:

 Kastle cards are issued to you prior to your move-in. Please contact your Property Manager for additional cards. It is very important that you keep track of those cards that are authorized for new employees and revoke any cards that are lost. Authorization and/or revocation of cards is performed by your Property Manager.

You may request a card listing for your firm by contacting Kastle Systems at 703.528.8800. Should you have any questions or concerns regarding Kastle and security cards please contact your Property Manager.

All visitors to Carroll Square must sign in and out with the Security Officer at the front desk. If you are expecting a large group of visitors, please provide a list with complete names ahead of their arrival to the Security Officer on duty. This will help facilitate the sign in process for your guests.
