Rolling WWS Maximum in Rijswijk: Cumulative Effects Over Multiple Years

In Rijswijk, a growing municipality in the Haaglanden region, the WWS maximum does not apply in isolation per year, but rolls over cumulatively across multiple periods. Landlords in neighbourhoods such as Innen and Remmerden may not skip the maximum in one year to double the increase later, for example in Plaspoelpolder, in accordance with Article 7:901 of the Dutch Civil Code (BW). The total increase over years may never exceed the compound maximum. Take 2023 with 2% and 2024 with 3.4%: the cumulation amounts to approximately 5.5%. Does a new increase exceed this in your Rijswijk rental property? Challenge it with the Rent Tribunal (Huurcommissie)! RVO calculates this via the rent index formula, while the Huurcommissie tool is essential for the unregulated sector. For housing associations such as Vidomes or Woonbron in Rijswijk, the DAB limit additionally applies. Local tenants often report 'catch-up' increases; these are invalid without judicial approval, especially given the tight market around Delft and The Hague. Demand transparency in your landlord's rent administration. In case of exceedance in Rijswijk, you can demand retroactive reduction plus compensation for damages. Keep a detailed rent history and compare annually with the national indices. This way, you protect yourself against creeping price inflation and maintain affordable housing as a long-term tenant in this popular municipality.
