Firehouse Subs was founded in 1994 by brothers Robin and Chris Sorensen in Jacksonville, Florida. The brothers were former firefighters with a family history in the fire service, which inspired the brand's firehouse theme. The first restaurant opened in an old fire station in Jacksonville, and the decor featured firefighting equipment, memorabilia, and a firehouse aesthetic.
The Sorensen brothers built the chain around a simple concept: hot submarine sandwiches made with steamed meats and cheeses, served on toasted rolls. The menu featured items named after firefighting terms, such as the "Hook and Ladder" and the "Engineer." The brand differentiated itself from competitors like Subway and Jersey Mike's by offering hot, steamed sandwiches rather than cold cuts.
Firehouse Subs grew through franchising, expanding from its Florida base into other southeastern states and eventually nationwide. By 2010, the chain had reached approximately 400 locations. The company was named one of America's fastest-growing franchises by Entrepreneur magazine and gained recognition for its strong unit economics and franchisee satisfaction.
In 2005, the Sorensen brothers established the Firehouse Subs Public Safety Foundation, a non-profit organization that provides funding for lifesaving equipment, training, and educational opportunities for first responders. The foundation has distributed over $20 million in grants to fire departments, police departments, and EMS organizations across the United States. The foundation is funded through customer round-up donations, a portion of franchise fees, and direct corporate contributions.
By 2021, when RBI acquired the chain, Firehouse Subs had grown to approximately 1,200 locations. The acquisition provided capital and operational expertise to accelerate growth. Under RBI ownership, Firehouse Subs has expanded its restaurant count to 1,496 as of December 2025, with 1,449 locations in the US and Canada and 47 international locations across 9 countries.
In 2025, Firehouse Subs achieved its strongest net growth in more than a decade, adding 43 restaurants year-over-year in the United States. The chain's average unit volume reached $960,000, with franchisee profitability per unit exceeding $100,000 for the first time. Four-wall EBITDA grew close to 30% since the RBI acquisition. The brand projects 105 new franchised outlets in 2026.

As part of RBI, Firehouse Subs is subject to the parent company's sustainability commitments. RBI has published ESG goals including reducing greenhouse gas emissions, improving packaging sustainability, and sourcing ingredients responsibly. However, Firehouse Subs' specific sustainability initiatives are less prominent compared to the foundation's public safety mission.
The chain sources its meats, produce, and baked goods through approved suppliers. RBI's supply chain management includes food safety standards, quality assurance protocols, and supplier audits. Firehouse Subs does not publicly report detailed sustainability metrics specific to the brand.
Firehouse Subs has received recognition for its franchise model and food quality.

Firehouse Subs has faced relatively few controversies compared to other quick-service restaurant chains. The brand has not been involved in major food safety scandals or labor disputes that have affected some competitors.
Like all QSR chains, Firehouse Subs has faced criticism over the nutritional content of its menu items. Some sandwiches contain high sodium levels and calorie counts, which has been noted by health advocates and nutrition organizations. The chain has responded by offering lower-calorie options and providing nutritional information on its menu and website.
The acquisition by RBI in 2021 raised some concerns among franchisees about potential cost-cutting measures and changes to operating procedures. 3G Capital, RBI's controlling shareholder, is known for aggressive cost management at its portfolio companies. However, Firehouse Subs franchisees have generally reported improved unit economics and support under RBI ownership.
