On April 4, 2006, Jackson County voters approved a tax increase to finance municipal bonds to pay for $850 million in renovations to Arrowhead and nearby Kauffman Stadium.
Before the bond election, the NFL awarded the 49th Super Bowl in 2015 to Kansas City provided it would have a climate-controlled stadium.
With the passing of the stadium bill, the Chiefs signed a new lease which ensures that the team will remain at Arrowhead until at least 2031.

However, a second bond issue to build the rolling roof shared with Kauffman Stadium that was part of the original 1967 stadium plan was defeated by voters, and Kansas City chose to withdraw its request to host Super Bowl XLIX in 2015; the game was played at the University of Phoenix Stadium (now State Farm Stadium) in Glendale, Arizona.

On August 15, 2007, the Chiefs announced final plans for the renovated Arrowhead Stadium, which would cost $375 million.
The cost to the city was reduced by $50 million thanks to an additional payment by the Hunt family, which originally had intended to donate $75 million.
The renovated stadium features the Chiefs Hall of Honor, a tribute to Lamar Hunt, and "horizon level" seating in which luxury suite owners sit outdoors.

Reconstruction for the stadiums started on October 3, 2007.
Refurbishment of nearby Kauffman Stadium, home to the Kansas City Royals baseball team, commenced at that time, and both completely-refurbished stadiums were ready for play by the 2010 season.
