Cost to Start a Denny's Franchise in 2026

Per the current FDD, total estimated initial investment for a traditional Denny's diner runs $1,618,375–$3,056,875, excluding land. Building construction and site improvements are the largest cost drivers:

• Franchise fee: $30,000
• Building and improvements: $950,000–$1,500,000
• Site improvements: $50,000–$500,000
• Equipment, fixtures and furnishings: $350,000–$450,000
• Signage: $80,000–$120,000
• Architectural design: $30,000–$60,000
• Technology platform (POS, kitchen display, back-office systems): $25,000–$40,000
• Opening inventory and supplies: $20,000–$30,000
• New restaurant opening training team: $0–$36,000 (scales down for multi-unit developers — roughly $36K for 1–2 restaurants, $26K for 3–4, $5K for 5+)
• Security deposits: $10,000–$15,000
• Insurance: $15,000–$20,000
• Permits, surveys and inspections: $5,000–$100,000
• Additional funds — working capital (3 months): $50,000–$150,000

Denny's requires prospective franchisees to demonstrate net worth of $1,000,000 or more and liquid capital of $500,000 or more. These are among the higher qualification bars in full-service dining, reflecting both the size of the investment and the brand's preference for financially durable, experienced multi-unit operators over first-time single-unit buyers.

Denny's fits a standard SBA 7(a)/504 deal size, but 2025–2026 system conditions — roughly 150 closures, a franchisee Chapter 11 filing, and a new private-equity ownership group — mean lenders underwrite more conservatively than they would on a growth-mode franchise system. Key factors:

• Trailing unit-level P&L over systemwide averages: Given the 2025 closure wave, lenders weight the specific site's (or, for an acquisition, the specific unit's) trailing 12–24 month sales and traffic trend far more heavily than brand-level average unit volume.
• DSCR 1.25×+ on conservative projections: SBA's floor is 1.15×; on a legacy full-service diner system with recent closures, lenders typically want 1.25× or better, modeled against flat-to-declining traffic assumptions rather than historical peak-year revenue.
• New-build vs. existing-unit acquisition: Acquiring an established, profitable Denny's with a documented operating history is generally easier to finance in the current environment than ground-up new development in an unproven trade area.
• Equity injection 10–20%: SBA minimum is 10% of project cost ($162K–$306K here); given system headwinds, some lenders push toward the higher end of that range or require additional liquidity reserves beyond the standard 3-month working capital line.
• Franchisor stability post-acquisition: The January 2026 change of ownership (TriArtisan Capital Advisors, Treville Capital Group, and Yadav Enterprises) is new enough that lenders will look for confirmation the FDD, franchise agreement terms, and franchisor support obligations are unchanged before closing.
