The George Mason School of Law is located in Hazel Hall on the Arlington, Virginia campus.  Hazel Hall was named after John T. Hazel, Jr., who was a prominent attorney, real estate developer, and one of the founders of the law school.  The 150,000 square-foot facility, which opened in 1999, spans four floors and includes classrooms, courtrooms, a library, and administrative and faculty offices.  In January 2011, a new adjoining 256,000 square-foot classroom building, Founders Hall, opened. Founders is primarily home to the School of Policy, Government, and International Affairs and a number of auxiliary university services.

Hazel Hall has six large tiered classrooms, seven seminar rooms, and two courtrooms. All of the classrooms and the two courtrooms are outfitted with the latest technology. Four classrooms and both courtrooms also have built-in digital recording and streaming capabilities. Hazel Hall has wired network connections in many of the classrooms and a building-wide wireless network. For a more detailed look at each classroom and the accompanying technology, see Classroom Descriptions and Equipment.

The law library spans four floors of Hazel Hall and has 270 carrels and table seats, nearly all of them wired with electrical and network connections so that students can plug in their laptops to access online resources.  In addition, the library has fourteen small conference rooms that may be checked out for group or individual study. The library operates two computer labs that provide both Windows PCs and iMacs and offer students a variety of software. The library also provides wireless access in all areas.

Hazel Hall has a large atrium (the Robert A. Levy Atrium) on the entrance floor that doubles as an events space and a lounge area for law students.

The law school uses space in Founders Hall for events and meetings. There is an auditorium that seats 300 and two large multipurpose rooms. Law students use common spaces throughout the building for casual study. Founders Hall houses the Arlington Campus Library and a large computer lab, which are both open to law students. The campus bookstore and an Einstein Bagels are also located in Founders on the ground floor adjacent to the law school's atrium.

There are two covered parking garages on the Arlington campus that are operated by Standard Parking. The campus is also situated within easy walking distance of two Metro stations, Virginia Square-GMU and Clarendon.

The Admissions Office provides an online self-guided tour of Hazel Hall. Prospective students can also sign-up for a formal tour and a class visit.
