Rent Adjustment After Improvements in Delft: Rules and Objections

In Delft, with its many historic rental properties and student flats, landlords often make improvements such as new kitchens or bathrooms. This may lead to a rent increase, but strict rules apply. Learn how the Rent Assessment Committee (Huurcommissie) and local authorities operate, and how to lodge an objection against unreasonable increases under the Dutch Civil Code (Burgerlijk Wetboek).

What Constitutes Improvements in the Delft Context?

Improvements are structural modifications that enhance the value of your property in Delft, such as energy-efficient windows or a modern central heating system, distinct from regular maintenance (Article 7:243 of the Dutch Civil Code). In social housing, which is common among housing corporations like DUWO in Delft, the Rent Assessment Committee must always approve such improvements. Consider renovations in neighborhoods like Buitenhof or Poptahof, where insulation is often a priority due to the older buildings.

Procedure for Rent Increase in Delft

Your landlord must inform you of the planned rent increase at least two months in advance. Within six weeks, you can lodge an objection with the Rent Assessment Committee in The Hague (serving Delft) or the subdistrict court (kantonrechter) at the District Court of The Hague, Delft branch. For liberalized rental properties in central Delft, a reasonableness test applies under Article 7:253 of the Dutch Civil Code. Local housing corporations such as Vestia often participate in pilot projects involving energy-saving measures, which may influence the procedure.

Tenant Rights in Delft

If you refuse to agree to the increase, the court will assess the fairness of the increase, taking into account Delft’s high property market pressure. Improvement costs, such as a new elevator in a student complex or insulation of historic buildings, may not be fully passed on to the tenant. Examples from recent Delft cases include moderate increases for double glazing or solar panels. Document everything—receipts, correspondence—and consult the Legal Counter (Juridisch Loket) in Delft for free advice. This will help you build a strong case.
