Do you think the amount of rent you pay is too high? There is a website for this in the Netherlands, huurcommissie.nl, where you can read what the maximum amount of rent is that is allowed. You can also call the Dutch government on telephone 1400 or +31 77 465 67 67. You can only contact this if there is a rental contract.
Do you think your home is unsafe? Do you live in a room or in a house with many people? Do you have a conflict with your landlord? In the Netherlands, ask the Juridisch Loket what you can do. You can also make an appointment by calling 0900 80 20.
Sometimes you can also contact Stichting Normering Flexwonen. This is possible if your home has a special quality mark, the SNF quality mark. Call the telephone number +31 (0) 13 594 41 09.
