Just applying an inflation adjustment isn't the whole story though. There's more people and more stuff than 20 years ago. New construction requires higher standards through code enforcement than 20 years ago. Infrastructure costs have ballooned way faster than inflation over 20 years, and repair/replace costs more to remove the broken stuff on top of just construction.
