Rolling WWS-maximum in Westland: cumulative effects over multiple years

In Westland, with its greenhouses and agricultural rental housing, the WWS-maximum does not apply only per year, but rolls over cumulatively across multiple years. Landlords in places such as Naaldwijk, Monster or Kwintsheul may not skip the maximum in one year to double rent later in Poeldijk or 's-Gravenzande, as laid down in Article 7:901 BW. The total rent increase over years may never exceed the compound maximum. Example: an increase of 2% in 2023 and 3.4% in 2024 amounts to approximately 5.5% cumulative. Does a new increase exceed this in your Westland property? Challenge it with the Huurcommissie! The RVO calculates this using the rent index formula, taking into account local inflation in the greenhouse horticulture region. For private sector rental properties in Westland, use the Huurcommissie tool; for housing associations such as Pré Wonen, the DAB-limit applies. In Westland, tenants often see 'catch-up' increases due to seasonal pressure on the housing market – these are invalid without judicial approval. Demand transparency in your landlord's rent administration. In case of exceedance, you can claim retroactive rent reduction and damages. Keep a detailed rent history, compare annually with Westland averages via the CBS and prevent creeping price inflation. This protects long-term tenants in the municipality of Westland against excesses.
