In Delft, the landlord is legally required to pay interest on the deposit from the first day of the tenancy. Article 7:204 of the Dutch Civil Code (BW) stipulates the statutory interest rate, currently around 2-6% depending on the year and the consumer interest rate. This interest accrues until the full repayment of the deposit. As a tenant in Delft, request an annual interest statement to avoid the statute of limitations after five years. In case of refusal: send a formal demand letter and keep all correspondence carefully documented.
Many landlords in Delft, particularly for student housing near TU Delft and the city center, deposit the security amount in a blocked account with foundations such as Woonborg or the Tenants' Interest Association Delft (Huurdersbelangenvereniging Delft). Verify this immediately at the start of the tenancy via the rental agreement or the local Delft Tenants' Team (Huurteam Delft). In Delft's rental market, with high demand for rooms and apartments, this is essential.
In case of negligence, you can turn to the Rent Tribunal in The Hague (available for Delft) or the subdistrict court at the District Court of The Hague, Delft location. Local tips: consult the Legal Counter Delft (Juridisch Loket Delft) for free advice or the municipality of Delft's website for tenant rights. This way, you maximize your rights in this student city.
