Houston's NRG Stadium opened in 2002. There are only six NFL stadiums more than 30 years old, and some of those will be replaced soon.

NRG Stadium, the Texans’ home since their inception, was completed in 2002 and cost $352 million. The stadium and surrounding NRG Park need $2 billion worth of repairs, according to a facility condition assessment released in December.

The Harris County-Houston Sports Authority still owes $1B in principal debt on bond money used to build NRG Stadium, Daikin Park and the Toyota Center. The Texans are also paid more in tax rebates than they pay in rent to play at NRG Stadium, so local government could be reluctant to offer more incentives.
