Please try lowering them temporarily until you are complete with your actions. If you don't have an NIH ID, please visit the NIH Parking Office to obtain a permit in person. 

Applying for a Parking Hanger (Join Parking)

In order to obtain a permanent parking permit on the NIH Main Campus, all vehicles must be register through the Employee Transportation Services Office (ETSO).  ETSO issues parking permits in the form of a rear-view mirror hanger to eligible employees. You may request a permit in one of two ways:
  • Applying online through CAPS.
    (To login you must be registered with NIH 2 factor authentication. If you are experiencing problems logging in using your NIH ID card or other error messages, please contact NIH IT Service Desk or (301)496-4357);
  • Obtain permit in-person at the ETSO/Parking Office.  NIH ID card is not required at time of enrollment. However, employees information must be in the NED system and employee must present a copy of valid vehicle registration in order to receive a parking permit.  Additionally, contractor or tenant, must be approved for parking in the NED system by your Administrative Officer.

NIH Parking Hangers are renewed on a yearly and bi-yearly basis, depending on the permit type.  Red and General permit types are renewed every two years, whereas all other types are renewed yearly.  Regardless of permit type, the expiration month and year of your permit will be displayed on the front and back of the hanger.
