Commercial lease: 7 risk clauses to identify before signing

A commercial lease commits your business for a minimum of 9 years. Variable rent, despecialization clause, joint guarantee: the traps to detect before signing.

Introduction

A commercial lease is one of the most significant commitments a business can make. The minimum legal term of 9 years, rent obligations and joint liability clauses can turn an ideal location into a financial trap.

The subblink team identified the 7 key points to examine before signing.

1. Rent indexation clause (ILC / ILAT)

Commercial lease rent is revised annually according to a legal index. A vague wording or an inappropriate index can lead to unpredictable increases.

Check: does the index applied match your activity? Is the reference period precisely defined?

2. Despecialization clause

The lease ties you to the activity precisely described in the contract. Adding any complementary activity requires the landlord's agreement and may trigger a rent review.

Check: is the authorized activity broad enough to cover your foreseeable developments?

3. Joint guarantee clause

If a partner acts as joint guarantor, they remain liable for rent even after assignment of the lease. This clause is often underestimated during business transfers.

Check: is joint liability limited in time and capped in amount?

4. Non-recoverable charges passed to the tenant

Some landlords include charges normally their responsibility (facade renovation, roof, structural compliance) in charges re-invoiced to the tenant.

Check: is the list of recoverable charges compliant with Articles L.145-40-2 and L.145-40-3 of the Code de commerce (Loi Pinel, 18 June 2014)?

5. Key money clause

Poorly qualified key money can mask an artificially low rent that will explode at the first revision.

Check: is it a "rent supplement" or "compensation"? The distinction is fiscally and legally decisive.

6. Triennial termination clause

Unless otherwise stipulated, the tenant can terminate every 3 years with 6 months' notice. Some leases exclude this right for the first 3 years.

Check: is your triennial termination right maintained or contractually limited?

7. Works and reinstatement clause

Upon exit, you may be required to restore the premises to their original condition. If significant works were carried out, the reinstatement cost can be considerable.

Check: must works be kept or removed? Is a precise entry inventory attached to the contract?
