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, Van Metre Hall (formerly Founders) opened. Van Metre is primarily home to the Schar School of Policy and Government 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 230 carrels and table seats, many of them wired with electrical connections or USB ports for charging smart devices. In addition, the library has two classrooms and fourteen small conference rooms that may be checked out by law students for group or individual study. The library operates a computer lab that provides both Windows PCs and iMacs and offers 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 Van Metre 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. Van Metre Hall houses the Arlington Campus Library and a large computer lab, which are both open to law students. The campus bookstore run by Barnes and Noble and Au Bon Pain are also located in Van Metre Hall 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.

Prospective students can sign-up for a formal tour and a class visit.
