The NIH has implemented security measures to help ensure the safety of our patients, employees, guests and facilities. All visitors must enter through the NIH Gateway Center at Metro, the West Drive Patient entrance (patient/patient visitor only) or the Commercial Vehicle Inspection Facility (during off-hours).  You will be asked to submit to a vehicle or personal inspection.

Visitors over 15 years of age must provide a form of government-issued ID such as a driver's license or passport. Visitors under 16 years of age must be accompanied by an adult.

Vehicle Inspections – All vehicles and their contents will be inspected upon entering the campus. Additionally, all vehicles entering certain parking areas will be inspected, regardless of any prior inspection. Drivers will be required to present their driver’s license and may be asked to open the trunk and hood. If you are physically unable to perform this function, please inform the inspector and they will assist you.

Vehicle inspection may consist of any combination of the following: Detection Dogs Teams (K-9), Electronic Detection Devices and Manual Inspection.

After inspection, you will be issued a vehicle inspection pass. It must be displayed on your vehicle’s dashboard while you are on campus. The inspection pass is not a "parking permit." It only grants your vehicle access to enter the campus. You can only park in designated parking areas. (See campus map above)​

Personal Inspections – All visitors should be prepared to submit to a personal inspection prior to entering the campus. These inspections may be conducted with a handheld monitoring device, a metal detector and by visible inspection. Additionally, your personal belongings m​ay be inspected and passed through an x-ray machine.

Firearms, explosives, archery equipment, dangerous weapons, knives with blades over 2 1/2 inches, alcoholic beverages and open containers of alcohol are examples of prohibited items on the NIH campus.

Visitor passes must be prominently displayed at all times while on the NIH campus.​
