The buildings in the Johnson Space Center house facilities of the National Aeronautics and Space Administration's human spaceflight activities. The center consists of a complex of 100 buildings constructed on 1,620 acres (656 ha)[1] located in southeast Houston, Texas.

A typical building at Johnson Space Center is numbered and not named. A partial listing of building numbers and what is contained in them follows:

Building Description Opened
1 Headquarters of JSC, including the offices of senior management and the JSC director 1963[2]
2 Public Affairs Office, Media briefing room, video production, and audio processing facilities (The JSC Visitors Center was a tenant until the opening of Space Center Houston[3] in October 1992). 1963[2]
3 Main cafeteria and JSC Exchange Store 1963[2]
4-N Mission Operations support offices including Flight Director's Office 1963[2]
4-S Mission Operations support offices and Flight Crew Operations Division (including Astronaut Office)
5 Space Mission Simulation Facility (including the recently retired Shuttle Mission Simulators, or SMS, the ISS Mission Simulator, and the Orion Mission Simulator) 1966[4]
7 Crew and Thermal Systems Division, including the vacuum chambers and space suit testing facilities, including the Environmental Test Article (ETA) Shuttle airlock vacuum chamber and the Space Station Airlock Test Article (SSATA) vacuum chamber. 1963[2]
8 Photographic Laboratory and Multimedia Operations Facility 1963[2]
9 Space Vehicle Mockup Facility (SVMF), including full-scale International Space Station module mockups and MPCV Orion developmental mockups. The Space Shuttle training mockups have been donated to outside organizations at the conclusion of the Space Shuttle Program, and have been removed. 1966/1967[4]
10 Engineering fabrication facility and machine shop 1963[2]
11 Satellite cafeteria and JSC Exchange Store 1966[4]
12 Office of Education, Human Resources Office, Language Lab, and Financial Management Division 1963[2]
13 Structures and Mechanics Laboratory 1963[2]
14 Electromagnetic compliance studies building 1966[4]
15 Human and Environmental Factors offices 1966?
16 and 16A Shuttle Avionics Integration Laboratory (SAIL), where software and hardware changes are tested to insure they function well with the whole vehicle in a simulated flight environment. Also houses the Shuttle Engineering Simulator (SES). 1963[2]
17 Space Food Systems Laboratory.[5] Offices for Space Exploration.
18 Morpheus Command Center
20 Safety and Mission Assurance, Office of Procurement
21 Human Health and Performance Laboratory 2017[6]
26 Columbia Center 2010
29 Crew Exploration Vehicle (CEV) Avionics Integration Laboratory; (CAIL) will be used to perform integrated avionics and flight software requirements verification. Originally served as the Weightless Environment Training Facility before the larger Neutral Buoyancy Laboratory was constructed to the north of the Johnson Space Center. The round portion of the building used to house a centrifuge which was used for astronaut training during the Gemini and Apollo eras. 1966[4]
30-A Mission Operations Directorate functional offices (Flight Design - FIDO, Ground Control - GC, etc.) The A in the building designation stands for Admin. 1965
30-M Christopher C. Kraft Jr. Mission Control Center - the historic Mission Control Center. This building is home to FCR1 (formerly MOCR-1) which is the flight control room for International Space Station, FCR2 (MOCR2) which is known as the Historic Apollo Control Room, as well as multiple controller consoles and the training flight control room (Red FCR). The M in the building designation stands for Main building. 1965
30-S Mission Control Center Space Station White FCR (formally the Space Shuttle control room, now ISS ), Blue FCR (interim Orion Control Room), as well as flight consoles and data facilities. The S in the building designation stands for Space Station as the entire building, especially the White Flight Control Room, was originally built-out for use by Space Station Freedom. During the build-out decisions were made to share resources between the Space Shuttle, station, and the White FCR, was changed to Shuttle during this process. 1993?[7]
31 Astromaterials Research and Exploration Science 1966[4]
31-N Lunar Sample Laboratory Facility
32 Space Environment Simulation Laboratory; two very large thermal-vacuum chambers for testing flight hardware, designated as a National Historic Landmark 1966[4]
33 Space Environment Simulation Test Facility with several small thermal-vacuum chambers for testing flight hardware 1966[4]
35 Guidance and Navigation Simulation Facility (Hosted a fixed base crew station of the Shuttle Mission Simulator, and offices)
37 Life Sciences Laboratory; formerly the Lunar Receiving Laboratory
41 Plant Operations Administration; formerly the Hypo/Hyperbaric Training Facility and Physiological Training Facility. Demolished on December 18, 2013. 1970[8]
44 Communications and Tracking Division;[9] formerly the Communications and Tracking Development Laboratory, Electronics Systems Test Laboratory and Audio Development Laboratory 1966
45 Project Engineering; also housed the Mission Evaluation Room 1966
45-N Occupational Clinic; formerly the Technical Library 1966[4]
48 Mission Control Power Plant
49 Vibration and Acoustic Test Facility[10]
110 Security headquarters just outside the NASA gates by the employee entrance. Security issues badges for employees, contractors, and visitors.
111 Industry Assistance Office
222 Atmospheric Reentry Materials and Structures Evaluation Facility; demolished in 2017. 1966
225 Administrative Support Facility Annex; formerly the Space Science Interim Facility; demolished on August 14, 2014. 1968[11]
226 Administrative Support Facility Annex; first building constructed at JSC.[12] Demolished on November 14, 2014. 1963
259 Astronaut Selection and Isolation Quarters 1967
260 Water Immersion Facility
263 Health Physics Laboratory
268A Planetary Analog Test Site, also known as the "Rock Yard". Simulates features of the lunar and Martian surface terrain, used for testing vehicle and spacesuit design[13]
