Missouri Commercial Lease Review Checklist

Reviewing a Missouri commercial lease step-by-step

The steps below walk through the provisions that most often drive commercial lease disputes in Missouri. Treat each as a prompt to read the actual lease language rather than relying on what either side said the deal would be.

Step 1: Confirm the basics

Verify the exact parties (including which entity signs and whether it matches the business that will operate there), the precise premises and any shared or common areas, the term length, and any renewal or extension options. Confirm how an option is exercised — the deadline and the required form of notice — because a missed window can cost you the right to stay.

Step 2: Understand the full rent picture

Look past the base rent to the total occupancy cost. Check for scheduled escalations and any pass-through charges such as common-area maintenance (CAM), and in a triple-net (NNN) lease the taxes, insurance, and maintenance you may owe on top of rent. Ask how those charges are calculated, capped, audited, and reconciled, since they can move significantly year to year.

Step 3: Check the permitted use and restrictions

Read the permitted-use clause to confirm it actually covers how you intend to operate, including likely future changes. Look for any exclusive-use protection you were promised, and for operating restrictions — hours, signage, build-out, or continuous-operation requirements — that could limit how you run the business or expose you to default.

Step 4: Pin down maintenance and repair duties

Identify who is responsible to maintain, repair, and pay for each major building system — typically the roof, HVAC, structural elements, parking, and utilities. Commercial leases often shift more of this burden onto the tenant than residential tenants would expect, so confirm in writing who fixes what and who pays, and watch for open-ended obligations to replace aging systems.

Step 5: Review assignment and subletting rights

Check whether you can assign the lease or sublet the space, and on what conditions. Many leases require landlord consent and may say that consent will not be unreasonably withheld — or may leave it to the landlord's sole discretion. These terms matter if you later sell the business, relocate, or need to exit early, so understand them before you are locked in.

Step 6: Scrutinize default, remedies, and any guaranty

Review what counts as a default, what notice and cure period you get, and the landlord's remedies — which may include acceleration of remaining rent, late fees, and attorney's fees. Pay close attention to any personal guaranty you would sign, since a guaranty is a separate promise that can reach you individually and may survive the business closing. Note whether it is unconditional or a more limited "good-guy" form.

Step 7: Confirm SNDA, estoppel, insurance, and indemnity

Look for a subordination, non-disturbance, and attornment (SNDA) provision that protects your tenancy if the landlord's lender forecloses, and understand any estoppel certificates you must sign. Then confirm the required insurance coverage and limits, any waiver-of-subrogation language, and the indemnity obligations — including whether you are agreeing to indemnify the landlord broadly.

Red flags to watch for

• Broad default definitions paired with short or no cure periods.
• An unconditional personal guaranty, or a guaranty broader than you expected.
• Uncapped CAM, tax, or insurance pass-throughs with no audit right.
• A self-help or lockout clause letting the landlord seize the space without a court process.
• Holdover rent set at a steep premium for "any portion of a month."
• Renewal or option deadlines that are easy to miss.
• One-sided assignment, relocation, or termination rights favoring the landlord.

When to talk to a lawyer

Because Missouri generally enforces a commercial lease as written, a review before signing is usually the cheapest moment to get advice. Consider talking with a qualified Missouri attorney if you are being asked to sign a personal guaranty, if the rent or pass-through structure is hard to model, if the maintenance or indemnity burden seems heavy, or if you are unsure what a default or remedy clause really means. A short review now can prevent a far costlier dispute later.
