In Delft, where rent prices in areas such as the city centre and TU campus often rise due to student pressure, your landlord may announce an unjustified income-dependent rent increase. Immediately start with a written objection within six weeks of receiving the letter. State concrete facts, such as incorrect income data from the Tax Authorities, exceedance of the maximum increase limit, or incorrect sector classification for your property.
The landlord in Delft must respond within six weeks. No satisfactory response? Then file a complaint with the Huurcommissie via huurcommissie.nl (cost €25). The commission checks your income above €47,699 (2024 threshold), the property sector, and the current index. In the event of a positive ruling, the landlord reverses the increase, refunds any excess rent paid plus statutory interest, and often covers your costs.
For urgent cases in Delft, you can involve the district court at the Rechtbank Den Haag – ideal in cases of threatened eviction. Gather evidence: rental agreement, income statement from the Tax Authorities, WOZ decision, and all correspondence. The Huurcommissie handles thousands of cases annually; in regions like Delft, the success rate for tenants is around 70% with proper substantiation.
Prevent payment by protesting immediately; retrospective settlement can be done via the commission, but it is cumbersome. Local Delft tenants often consult Huurteam Delft for free advice and model letters, or the Woonbond. Also check delft.nl for municipal rent assistance in special circumstances such as starter homes near the Technopolis.
