Short definition

French rent index for tertiary leases.

Full definition

Office leases in France typically index annually to the ILAT. Caps are negotiable. Replaced ICC (Indice du Coût de la Construction) for tertiary leases in 2014.

Why this matters for Class A leasing

ILAT (Indice des Loyers des Activités Tertiaires) is part of the lease economics vocabulary that institutional Class A occupiers, landlords, and advisers use across EU markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the EU definition alongside the global standard so cross-border occupiers can translate quickly.
