CEFCU Stadium was the home of the San Jose Earthquakes (originally San Jose Clash) of Major League Soccer from the league's inception in 1996 through the 2005 season. Other tenants have included the original San Jose Earthquakes of the North American Soccer League from 1974 to 1984, the San Jose CyberRays of the Women's United Soccer Association from 2001 to 2003, and the San Francisco Dragons of Major League Lacrosse in 2008. Soccer Bowl '75 was also held at Spartan Stadium.
During the winter and spring of 2009, the stadium's natural turf was removed and replaced with FieldTurf, a new generation of artificial turf with a crumb rubber and sand infill. This improvement has resulted in significant savings to the university in water use, fertilizer and seed. This project was completed in time for the May 2009 commencement ceremony.
The stadium also received significant upgrades to the scoreboard and sound system in 2011. This included installation of a high-definition video board (commonly called a JumboTron) by Daktronics at the south end of the stadium.
Originally built 84 years ago in 1933 as a 4,000-seat facility, CEFCU Stadium has been renovated and expanded over the years to its present seating capacity of 30,456. The most recent additions came in the late 1980s when the capacity of the stadium was expanded from 18,000 to approximately 33,000 by adding boxes and an upper deck on the west side. In the early 2000s, renovations were carried out for the San Jose Earthquakes in order to make the field wide enough for a FIFA regulation size field. As a result of these renovations, parts of the stands closest to the playing field were removed, thus lowering available seating for all sports to the stadium's present capacity of 30,456. The maximum capacity for MLS games is 26,525.
In August 2016, Citizens Equity First Credit Union purchased naming rights to Spartan Stadium for $8.7 million. The deal between CEFCU and San José State University will last for 15 years. SJSU is the only university in the California State University system to sell the naming rights to its football stadium. At the time, SJSU was one of three member universities in the Mountain West Conference to strike such a deal, with one other MW member playing in a municipally owned stadium that was also named through such a deal. Two more MW schools have since made similar naming rights deals for their football stadiums. The $8.7 million raised by the agreement will primarily be used for athletic scholarships, athletics operations, and athletics facilities.
