The original stadium consisted of the lower half of the current facility's grandstand seats. In 1940, field-level lights were added, and Georgia played its first night game against
Kentucky to a 7–7 tie. The stadium's first major expansion took place in 1949, with the addition of 6,000 seats on the south side, bringing total capacity to 36,000. During the 1960s, many universities in the
South were significantly expanding their stadiums, and Georgia was no different. Soon after the arrival of head coach
Vince Dooley in 1964, UGA began updating Sanford Stadium, removing the field-level lighting (which obstructed views from the stands) and adding 7,621 bleacher seats in the end zones, which brought total capacity to 43,621. Architects
Heery and Heery of Atlanta were then hired to plan a major expansion. This expansion planning was very tricky, since by that time the stadium was encroached by academic buildings. The plans went forward, however, and the grandstand seats were double-decked in 1967 without the need to demolish or alter any of the surrounding buildings. In addition to the new upper decks, this first major addition included a new pressbox and club seating. In total, 19,640 seats were added to the stadium (bringing total capacity to 59,000), at a cost of $3 million. The new addition was christened with a victory over
Mississippi State in 1967. In 1981, the east endzone was enclosed at a cost of $11.5 million, turning the stadium into a "horseshoe" and eliminating the free view enjoyed by the "Track People". This addition added 19,000 seats, bringing total stadium capacity to 82,122. The first game in the newly expanded stadium was on September 5, 1981, against
Tennessee, with Georgia delivering a 44–0 drubbing. Lights were re-installed in the stadium in 1981. This time, the lights were not located at field level, but built above the upper level, thus not obscuring views of the field. The first game under the "new lights" was a 13–7 victory against
Clemson on September 6, 1982. In 1991, a portion of the west endzone was enclosed, creating a "partial bowl" around the lower level of Sanford Stadium. The west stands could not be completely enclosed due to the proximity of Gillis Bridge (usually called "Sanford Bridge"), a major campus transportation artery, to the stadium. This expansion cost $3.7 million and added 4,205 new seats, bringing total capacity to 85,434. 30 luxury suites were added above the south stands in 1994, and were expanded to 50 suites in 2000. These expansions cost a total of $18 million, and raised total capacity to 86,520. In 2003, another upper deck was added to the north side of the stadium. It added 5,500 new seats at a cost of $25 million, bringing total stadium capacity to 92,058. Most of these "upper-upper deck" seats are reserved for the fans of the visiting team. In 2005, installation of a new video display above the west end zone was completed. Ribbon boards were also added along the sides of the stadium. These additions, constructed and maintained by
Daktronics, established Sanford Stadium as one of the most visually media intensive venues in the
SEC. The stadium reached its capacity of 92,746 in 2004, when 27 SkySuites were added to the north side of the stadium at a cost of $8 million. The video board installed from 2005 underwent a $1.4 million overhaul before the 2011 season. The screen size expanded from 25×46 feet to the full scoreboard size of the 52×76 feet. The new video board has full high definition (HD) capability. On February 14, 2017, the UGA Athletic Board approved a $63 million expansion to renovate the west side of the stadium. The approved design relocated the locker room from the east side to the west side and added a new plaza and recruiting pavilion. Construction began following the 2017 season and was officially opened with a ribbon-cutting ceremony on August 31, 2018, a day before Georgia's first home game of the 2018 season. In 2019, the floodlighting system was upgraded to a state-of-the-art
LED system, which cost around $950,000. In 2022 Georgia announced renovations to be completed by the 2024 season. The renovation included the expansion of the 100-level south sideline concourse; the creation of the 50 Yard Line Club; expansion of gate 9; more restrooms; and a new press box with premium seating offerings. The renovation added 287 seats to have a total of 93,033. ==Notable Sanford Stadium games==
