NIH Parking Permits (Apply & Renew)

 CAPS Logo 

Using our web-based application, commonly called Commuting and Parking Services (CAPS), eligible NIH employees can apply, renew, and modify information at any time.
CAPS is supported in Microsoft Edge, Chrome, and Apple Safari. If you receive an error message when trying to log in, the security settings on your browser may be too high. Please try lowering them temporarily until you are complete with your actions. If you don't have an NIH ID, please email the NIH Parking Office with your parking request at  

Applying for a Parking Hanger (Join Parking)

To obtain a permanent parking permit for the NIH Bethesda Campus, all vehicles must be registered 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
  • Email parking permit request to Include NIH ID number, local home address, and a copy of a valid vehicle registration with the employee's name on the registration. Additionally, contractors or tenants must be authorized for parking in the NED system by an Administrative Officer.

*If unable to apply for a permit online, please email or call 301-496-5050.


It is the responsibility of the permit holder to adhere to all applicable policies, regulations, and laws while using the NIH Parking Permit. The ETSO attempts to inform the NIH staff of parking policy changes using global email.  In specific cases, the use of website alerts, fliers, signs, and news articles may be utilized. ETSO is not involved with or responsible for any parking citations or law enforcement actions taken on the NIH Campus.  Those enforcement matters should be addressed to the NIH Division of Police. The use of NIH parking permits is the sole responsibility of the user to ensure they are up-to-date and compliant with all parking policies and regulations.

  • Any person who knowingly makes a false representation on this application may be subject to a criminal prosecution potentially resulting in a fine or imprisonment, or both, pursuant to 18 U.S.C. 1001 and to disciplinary actions, including the revocation of parking privileges, pursuant to 5 U.S.C. Chapter 75 and 5 C.F.R. Part 752.
  • The parking permit (hanger) is the property of NIH and must be returned to the NIH Division of Amenities and Transportation Services (DATS) upon separation from the Government or when the holder is no longer eligible for the permit.
  • The permit cannot be transferred.
  • The permit must be properly displayed while parked on the NIH Campus – Bethesda, Maryland, and is valid through the last day of the month and year displayed.
