Collecting Evidence for WWS Exceedance in Rotterdam: Checklist for Tenants

In Rotterdam, where rental prices in neighbourhoods such as Kralingen, Delfshaven and the Old North often exceed the WWS limit, watertight evidence is essential to successfully challenge a rent increase. Use this Rotterdam-specific checklist: 1) Download the official WWS maximum from RVO.nl for your rental year and compare it with Rotterdam real estate developments. 2) Note the original and new rent from your lease agreement, termination letters and any adjustments via the Rotterdam Huurpunt. 3) Calculate the exceedance percentage: (new - old rent) / old rent x 100 – pay attention to the stricter controls in the city. 4) Keep bank statements of rent and service charge payments, crucial for Rotterdam housing associations such as Woonbron or Vestia. 5) Collect all correspondence with the landlord, including emails about maintenance in the port city. Article 7:900 of the Dutch Civil Code (BW) stipulates that increases must be announced in writing and in a timely manner (at least 2 months); if this is missing, the increase is null and void. Add local housing data, such as the Rotterdam address, WOZ value via the municipal website and sector confirmation via the Land Registry. Use the Rent Tribunal simulator and check Rotterdam rent teams for advice. In case of dispute: submit within two months to the Rent Tribunal for the unregulated sector. With this evidence, you can force cancellation, repayment and avoid fines. Stay proactive, document everything and enlist local Rotterdam tenants' associations for extra support.
