In a commercial lease, the parties can plan from the signing of the lease how the rent will evolve during its duration.
The lease may include, in particular:
When the rent is indexed , the lease should specify the index used, the date on which the adjustment is calculated, the reference period and the applicable calculation method.
The lease may also stipulate a minimum or maximum increase , or specify that the rent cannot decrease even if the index used falls.
It is important to distinguish between an increase in base rent and a change in additional charges. Taxes, operating expenses, and other charges can increase or decrease based on the building's actual expenses, independently of the planned increase in base rent.
The mechanisms for rent increases should therefore be clearly defined in the lease so that the landlord and the tenant can determine the applicable rent during each of the lease periods and better predict the evolution of the cost of renting.
