This $500 million project started construction in 2003, under the South Coast name. Based on advance booking, Coast Casinos announced expansion plans to add additional hotel rooms, with a second tower, for a total of 1,350 rooms. The foundation was also poured for a possible third tower during the initial construction phase.
The casino received approval to open from the Nevada Gaming Commission on November 17, 2005. At opening on December 22, 2005, the South Coast was the first megaresort located south of McCarran International Airport and the Las Vegas Strip. The hotel contained 662 rooms and 800,000 sq ft (74,000 m2) of space that was not finished and was available to be converted into restaurant or casino space.
In mid July 2006, it was announced that Michael Gaughan would sell all of his Boyd stock to Boyd gaming in exchange for full ownership of the South Coast. The Nevada Gaming Commission approved the sale on October 19, 2006. After the deal closed, the South Coast was renamed South Point on October 24.
On August 24, 2007 the South Point announced an 830 room expansion with construction of the third hotel tower, turning the hotel towers into a "T"-shaped facility as seen from above. The $95 million expansion, planned for completion in July 2008, would add 10,000 sq ft (930 m2) of convention space and 5 food and beverage locations. The third tower opened on July 21, 2008 with the hotel now offering a total of 2,163 rooms and 160,000 sq ft (15,000 m2) of meeting and convention space; the largest of any hotel in Las Vegas that is not on the Strip.
