The Restaurant Due Diligence Checklist for Buyers (2026)

Due diligence is the homework that protects your money. Once you have a signed letter of intent (LOI) on a restaurant, you typically get a window — often 30 to 60 days — to verify that everything the seller claimed is true before the sale becomes binding. Skip it, and you can inherit hidden debt, a non-transferable lease, or equipment that dies a month after closing. This is the checklist serious buyers (and their brokers) work through, item by item.

1. The Financials — Prove the Money

This is the heart of due diligence. You're verifying that the income the seller advertised is real and repeatable.

3 years of tax returns — and confirm they match what you were told.
3 years of profit-and-loss statements — cross-check them against the tax returns and the POS reports. They should tell the same story.
POS sales reports — pull the raw data; this is the hardest number to fake.
Bank statements — deposits should line up with reported sales.
The add-backs — every "add-back" the seller used to inflate SDE (their salary, personal expenses, one-time costs) should be documented. If they can't prove it, don't pay for it.
Sales trend — is revenue flat, growing, or quietly declining? A downward trend the seller didn't mention is a red flag.

2. The Lease — Often the Real Deal-Maker or Breaker

You can buy a perfect restaurant and still have no business if the lease falls apart. Verify:

Remaining term + renewal options — a great restaurant with two years left and no renewal is a risk at any price.
Assignability — can the lease transfer to you, and will the landlord approve it? Get this confirmed in writing early.
Rent and escalations — base rent, CAM, taxes, insurance (often "triple-net"/NNN), and how much rent rises each year.
Personal guarantee — will the landlord require one from you?
Permitted use and any landlord restrictions — hours, signage, exclusivity.

3. Licenses, Permits & Legal

Business license and health permit — current and in good standing, with the last inspection report.
Liquor license — confirm it's transferable (in many states this is a slow, separate approval) and that there are no violations.
Certificate of occupancy and any required fire-marshal sign-offs.
Liens and debts — run a UCC/lien search so you don't inherit money owed against the equipment or business.
Pending lawsuits or violations — ask directly and verify.

4. The Physical Asset — Equipment & Space

Equipment list — get it in writing, and confirm what actually conveys with the sale (leased equipment may not).
Test the big-ticket items — walk-in cooler/freezer, hood and fire-suppression system, HVAC, grease trap. These are five-figure repairs if they fail.
Service records and warranties for major equipment.
Condition of the build-out — plumbing, electrical capacity, any deferred maintenance you'll be paying for.

5. Operations & People

Staff — who stays, who's key, and what they're paid. Will the chef or GM remain through a transition?
Vendor contracts — supplier terms, any exclusivity, and whether they transfer.
Recipes, systems, and SOPs — are they documented, or do they live only in the owner's head?
Online presence — reviews, social accounts, and reservation/delivery platform access. Confirm these convey.
Reason for selling — pressure-test it. "Retiring" is common and fine; a vague answer hiding a lease problem or a new competitor across the street is not.

The Deal-Killers to Catch Early

Front-load these — they can end a deal before you spend weeks on the rest:

A non-transferable lease or a landlord who won't assign.
Books that don't reconcile — tax returns, P&Ls, and POS that don't match.
A liquor license that can't transfer (or comes with violations).
Undisclosed liens or debt attached to the business or equipment.
A failing hood, walk-in, or fire-suppression system the seller "forgot" to mention.

How to Run It Smoothly

Put every request in one organized list and give the seller a deadline. Use your accountant for the financials and an attorney for the lease and purchase agreement — their fees are tiny compared to the cost of a bad deal. And keep the relationship professional: due diligence isn't an attack, it's standard practice, and a good seller will have most of this ready.
