In Delft, with its mix of historic social housing and private sector apartments around the city centre and the TU campus, alongside the income-dependent rent increase, the regular increase based on inflation (CPI) plus 1% also applies for housing associations such as Woonbron and Vestia that are active in the city. For 2024, this maximum in the private sector has been set at 5.4%, as determined in the Regeling Huurprijzingering. Landlords in Delft may not simply combine both forms; the income-dependent increase applies exclusively to household incomes above the threshold of €47,699 for housing associations.
The inflation adjustment must be announced before 1 May via a written notice, fitting the stringent Delft rental market where students and young professionals often face rapid price increases. Tenants in neighbourhoods such as Poptahof or around the Nieuwe Delft can challenge both types of increases with the Huurcommissie, which handles many cases locally due to the high occupancy rate. Document all correspondence carefully, especially for applications for rent allowance via the municipality of Delft, which provides extra support to low incomes.
The Autoriteit Wonen provides national supervision, but locally the municipality of Delft monitors excesses via its Wonen-team. These dual systems balance the income of landlords in a city with rising real estate prices with the protection of tenants, who in Delft are often young professionals and families. Check your rental agreement annually and consult local advice centres such as the Juridisch Loket in Delft for personal situations.
