Street Parking

There is limited free parking on the West side of the building on 4th Street.  Two-hour metered parking is available in front of the building along E Street and along 3rd Street at a rate of 25 cents per 8 minutes (approximately $2 per hour).  The two-hour limit is strictly enforced regardless of whether or not time remains on the meter. 

Private Parking Lots Close to HQ

The following private parking lots are close to Headquarters.  All are operated by Colonial Parking.  Fees shown are subject to change.  In some cases, you may apply for a monthly parking permit at the Colonial Parking Web site.

  • Open-air lot at 500 E Street ($12 per day).  Open 7 a.m. – 7 p.m., this lot at the corner of 4th and E Streets is usually full by 8:15 a.m. 
  • Underground lot at 425 3rd Street ($16 per day).  Open 5 a.m. – 7 p.m., this lot is usually full by 8:00 a.m.
  • Underground lot at 400 Virginia ($16 per day).  Open 6 a.m. – 9 p.m., this lot is usually full by 9:30 a.m. 
  • Partially covered lot at 6th Street at Maryland Avenue ($8 per day).  This lot, beneath a freeway, is usually full by 9 a.m.  It is a short walk to HQ but many find the route tricky to navigate for the first time.  Due to its structure and lack of visibility, this lot is generally considered unsafe after dark. This is the only parking lot close to Headquarters open on Saturday and Sunday.

Entry Procedures

Plan to arrive at least 15 minutes prior to your meeting to allow adequate time to complete mandatory security procedures.  Special instructions apply to Foreign Nationals.
All visitors must enter through the visitor’s entrance which is located on the West side of the NASA HQ building.  You will obtain a visitor’s badge, then complete a security inspection of your bags and walk through a magnotometer.

Obtain a Visitor’s Badge

Report to the Visitor Control Center to obtain a visitor's badge. 
You will be required to provide the following:

  • Picture ID (valid driver’s license recommended)
  • Your contact’s phone number
  • Citizenship status
  • Purpose of your visit
  • Your agency or company name, if applicable

A Security Officer will call the person you are visiting to verify your appointment.

Security Inspection

Once you have your visitor’s badge, proceed to the x-ray equipment and place any bags (purses, backpacks, briefcases, etc.) on the conveyor belt.  Remove any electronic devices or metal items such as cell phones, pagers, keys, etc. from your person, and place them on the table to your right.  A Security Officer may request that you identify an object or run it back through the x-ray machine for clarification.  When prompted, walk through the metal detector. Reclaim all of your possessions.
Official photographers assigned to NASA Headquarters and professional photographers and news media with credentials or on an approved visit request are not required to run their camera and film bags through the X‑ray machine providing that a visual inspection is made.  If the individual declines a visual inspection, he/she will not be granted access to the facility.
What items may be inspected?

  • Packages
  • Briefcases
  • Purses
  • Other containers
  • Vehicles

Foreign National Access

While NASA encourages visits by foreign nationals or representatives of countries allied with or friendly to the United States, all types of foreign visit requests are screened to determine whether they conform with agency and national policies, including U.S. national security, missile technology and foreign policies, and U.S. export control regulations.

All Foreign Nationals visiting NASA Headquarters require prior approval from the Headquarters International Visit Coordinator. All Foreign Nationals requiring computer access and those from Designated Countries require approval at the agency level.

All Foreign National visitors must be entered into the NASA Foreign National Management System (FNMS). The NASA Foreign National Management Systems (NFNMS) is an agency-wide secure database that facilitates the coordination, review, decision process, and tracking of all foreign national access to NASA facilities.

Entry Process for Foreign Nationals

  • Your point of contact should have already obtained all necessary approvals prior to your scheduled visit, and shared this with the Visitor Center in the West Lobby.
  • You will be asked to display a valid picture ID and sign-in.
  • Then you will receive a visitor badge.
  • As with all visitors, you will be asked to walk through the magnetometer and your hand carried items will be X-rayed.
  • Your sponsor will meet you at the Visitor Control Center and escort you throughout your visit to NASA HQ.  Your visit to the HQ building must fall within these time periods: Monday - Friday, 7 a.m. to  7 p.m.

IT Needs of Your Visitor(s)
As a visitor’s point of contact or sponsor, it is important to establish any special IT needs your visitor may have in advance of their visit.  For example, you may need to:

  • Request Guest Network credentials for visitors who are not NASA-badged
  • Request IT Security scan of NASA-badged visitor laptop(s) if NASA private network access is required.
  • Request meeting or office space, telephone, and other IT access as necessary, using the system(s) of record.

It is vital that you understand the difference between the Private HQ Wireless Network (for HQ users) and the Guest Wireless Network.  The Guest Network does not provide access to HQ internal resources such as Intranet applications and file shares. While HQ users may use the Guest Network (for example, if they have brought their own device to work), use of the Wireless Network intended for HQ users is restricted to HQ users using NASA-issued equipment.  Under no circumstances should you share your own login credentials with your visitor(s), nor login to your computer and then allow others access to it.

It is quick and easy for you as an HQ user to obtain credentials on behalf of your visitor(s).  Simply visit the Guest Network Credentials Web page (NASA only).  Your visitors may also obtain credentials directly from the following locations:

IT POCs and event sponsors may request any number of 1-day or 2-week passes in advance of an event by contacting the Enterprise Service Desk (ESD) at 358-4357.  If you require a single username and password to distribute to a group of visitors, please allow extra time for approvals and processing.

Refer to the Guest Network Web page for detailed information, including Login Instructions and Frequently Asked Questions.
