Short definition

The contractual start date of the lease term.

Full definition

Distinct from the rent commencement date. The lease may commence on signing while rent does not start until construction completion. On heavy fit-outs, structure rent commencement to the later of (a) lease execution + agreed window, or (b) substantial completion.

Why this matters for Class A leasing

Lease commencement date is part of the lease structure vocabulary that institutional Class A occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so cross-border occupiers can translate quickly.
