BurgerFi is building-out at Jacksonville International Airport.
The city issued a permit March 23 for Auld & White Constructors LLC to renovate 1,451 square feet of space for BurgerFi at a cost of $800,000.
BurgerFi will occupy the former Brooks Brothers store in the post-security area.
The Jacksonville Aviation Authority said previously that it would be completed by late summer.
Brooks Brothers closed and does not plan to reopen.
BurgerFi is one of three restaurant groups opening new locations at the airport.
Jacksonville-based restaurants Firehouse Subs, Southern Grounds & Co. and Burrito Gallery also are opening new locations in 2023.
Post-security, Firehouse Subs is moving to a larger space in Concourse C as it loses its existing post-security space during construction of Concourse B.
Burrito Gallery will open in Concourse A.
Southern Grounds recently opened in Concourse A and also will expand pre-security.
Southern Grounds will open a restaurant in the pre-security space previously occupied by Starbucks, Made in JAX and parts of the airport gallery.
At 2,400 square feet of space, it will be double the size of the Southern Grounds on Concourse A and offer diner seating, an all-day menu, a full-service bar and its blueberry bakery.
