Rent harmonisation, also referred to as tenancy change, is a scheme which allows the rent of a dwelling to be increased by more than the maximum rent increase applicable for that year once there is a new tenant. This is unrelated to the annual rent adjustments as of 1 July and may be applied at any time. The rent after harmonisation may not exceed the maximum permitted rent based on the valuation system (point system) of the Ministry of the Interior and Kingdom Relations. The calculated tenancy change may consist of two components:
1. the change of rent during the change of tenant;
2. the annual rent adjustment as of 1 July (where applicable).
Dwelling renovations are another reason for rent increase. However, the new rent may not exceed the maximum permitted rent. Rent increases as a result of renovations are not included in the calculation of rent developments.
