Firehouse Subs Headquarters Address, Corporate Office Location, and Contact Details

About

Firehouse Restaurant Group, Inc. — doing business as Firehouse Subs — is an American fast-casual submarine sandwich chain headquartered at 4600 Touchton Road E., Building 100, Suite 300, Jacksonville, Florida 32246 — in the Deerwood North office park on Jacksonville’s southside — which became Firehouse Subs’ corporate home on April 1, 2025, following its relocation from its previous headquarters at 12735 Gran Bay Parkway, Suite 150, Jacksonville, FL 32258 (Flagler Center, about 10 miles south). Firehouse Subs was founded in 1994 in Jacksonville, Florida by Chris and Robin Sorensen — two brothers and former firefighters — and has grown from a single Jacksonville restaurant into a 1,000+ location fast-casual chain across the United States and internationally. In December 2021, Firehouse Subs was acquired by Restaurant Brands International Inc. (NYSE: QSR) — the parent company of Burger King, Tim Hortons, and Popeyes — for $1 billion, with RBI committing to keep the brand headquartered in Jacksonville.

The new Deerwood North headquarters features an open-concept office designed to fuel collaboration, with a second phase of renovations — including an innovation kitchen and a new mural studio — underway in 2025. Firehouse Subs’ mission extends beyond sandwiches through the Firehouse Subs Public Safety Foundation® — the brand’s nonprofit that has donated tens of millions of dollars in life-saving equipment to first responders, public safety agencies, and disaster relief organizations across North America. Firehouse Subs has been named the #1 brand in the restaurant industry that “Supports Local Community Activities” for four consecutive years per Technomic Insight consumer data.

About the 2025 Deerwood North relocation and Firehouse Subs’ Jacksonville legacy: Firehouse Subs’ April 2025 relocation from the Flagler Center office park on Jacksonville’s far southside to the Deerwood North complex at 4600 Touchton Road E. — about 10 miles north and east, in the heart of Jacksonville’s Southside commercial corridor — represents the brand’s most significant real estate upgrade since its 2021 acquisition by Restaurant Brands International. The new Deerwood North headquarters — featuring an open-concept layout, innovation kitchen, and mural studio — reflects RBI’s ongoing investment in the Firehouse Subs brand infrastructure, consistent with its commitment to maintain the Jacksonville headquarters made at the time of the $1 billion acquisition. Firehouse Subs’ 31-year Jacksonville heritage — tracing a trajectory from a single Mandarin sandwich shop in 1994, through the Flagler Center era, to the Deerwood North campus today — makes it one of the most significant Jacksonville-born consumer brand success stories in Florida history.
