Buying a Restaurant: Due Diligence Checklist: The 2026 Complete Checklist

When acquiring a restaurant, your buying a restaurant due diligence checklist needs to cover unique risks that don’t appear in most other small-business deals.

The operations portion of your buying a restaurant due diligence checklist includes recipes, vendor relationships, kitchen equipment condition, and labor structure.

Restaurant acquisitions have specific diligence requirements that don’t apply to most other small businesses. Tight margins (typical 5-15% restaurant operating margins), heavy regulatory oversight (ABC liquor, health department, signage), labor-intensive operations (60-70% of revenue often in food + labor combined), and lease terms that can include percentage rent, exclusive use, or radius restrictions all require careful evaluation.

A complete buying a restaurant due diligence checklist covers 7 categories specific to food-service businesses, each requiring buyer scrutiny.

This checklist covers all 7 categories of restaurant-specific due diligence with items every buyer (and seller preparing for sale) should review. It’s derived from National Restaurant Association best practices, IFA (International Franchise Association) standards for franchise-restaurant deals, and 2026 M&A practitioner consensus.

CT Acquisitions runs sell-side M&A processes for founder-owned U.S. businesses including restaurant operators ($1M-$25M EBITDA). We help sellers prepare for the unique diligence demands of restaurant buyers and connect them to active restaurant-platform PE (MFG, NRD Capital, Roark Capital, etc.).

Frequently Asked Questions: Restaurant due diligence

What is restaurant due diligence?

The process of investigating a restaurant target before acquisition. Covers 7 categories specific to food-service: Financial, Operations, Real Estate & Lease, Licenses & Permits, Food Safety & Health, Employment & Labor, Customer & Marketing.

What is “prime cost” in a restaurant?

Prime cost = food cost + labor cost as % of revenue. Target: under 65%. Above 65% signals operational problems, recipe issues, or pricing problems.

What makes restaurant deals risky?

Tight operating margins (5-15%), heavy regulatory oversight (ABC, health department, signage), labor-intensive operations, percentage rent that can compress margins, ABC liquor license transferability complications, post-COVID staffing challenges.

How long does ABC liquor license transfer take?

Varies by state. California: 30-90 days typical. Most states 30-60 days. Plan accordingly in deal timeline.

What is percentage rent?

Lease clause requiring tenant to pay additional rent equal to a percentage of sales above a threshold. Common in mall and retail restaurant locations. Can materially compress margins as sales grow.

Asset purchase or stock purchase for restaurants?

Asset purchase is typical: buyer takes equipment, leasehold improvements, inventory, goodwill, brand. Leaves behind entity-level liabilities. Lease assignment + ABC license + health permits all require separate transfers.

What does the POS data tell me?

Sales validation (matches deposits?), day-part trends, average check, customer counts, repeat customer frequency. Critical for validating seller-provided revenue figures.

What employment issues are unique to restaurants?

Tipped employee FLSA compliance (regular rate, overtime), state-specific tip credit rules (CA prohibits tip credit), I-9 compliance (high-turnover workforce), wage and hour litigation risk, meal/rest break enforcement.
