Housing Valuation System and Rent Determination in Delft

The Housing Valuation System (WWS) determines the maximum rent price for dwellings in the regulated sector in Delft, via a points system based on floor area, facilities, and the WOZ value. In Delft, where the rental market is under pressure due to the proximity of TU Delft and many students, this applies strictly: rent prices above the liberalisation threshold (€900 in 2024) fall into the free sector. Landlords in neighbourhoods such as the city centre or Poptahof may not add points arbitrarily; always check your rent via huurcheck.toeslagen.nl. For rent increases, the price must remain within the WWS, which is particularly relevant in Delft due to the high demand for affordable housing. The Rent Tribunal can carry out a revaluation upon objection, taking into account local factors such as the condition of monumental buildings in Delft. Recent national changes also apply here: extra points for sustainable insulation in energy-efficient rental dwellings, but deductions for defects such as moisture problems in older TU neighbourhoods. Tenants in Delft can challenge the appropriateness of their rent, especially in the transitional sector where the WWS still applies. This system protects Delft tenants against excesses and ensures transparency in the tense local market.
