The Netherlands has an extensive rent regulation system with different rules for social housing, mid-range housing, and the free sector. The Affordable Rent Act (Wet betaalbare huur), fully implemented in 2026, ensures that properties up to 186 WWS points are rent-controlled.
The Housing Valuation System (WWS)
The WWS is a point-based system that determines segments based on surface area, energy label, and WOZ value. As of 2026, if a property has 186 points or fewer, it must adhere to the maximum rent set by the government.
Housing Segments (2026)
Rules by Segment
Social Housing
- Maximum rent determined by WWS point total.
- Annual increase maximum 4.1% (effective July 1, 2026).
- Additional income-dependent increases may apply for high-earning households in social units.
Mid-Range Housing (Middenhuur)
- Covers properties between 144 and 186 points.
- Maximum increase of 6.1% (Wage Growth + 1%).
- Landlords must provide the WWS point calculation with new contracts.
Free Sector (Private Sector)
- No maximum starting rent.
- Annual increase limited to 4.4% (CPI inflation + 1%) as of January 1, 2026.
- Landlord must provide the WWS point calculation so the tenant can verify the property is truly "liberalized" (187+ points).
Rent Increase Procedure
Annual Increase
- Written proposal: Must be sent at least 2 months before the effective date (typically by May 1 for a July 1 increase).
- Statement of percentage: Must specify the percentage and the new total rent.
- Right to object: Tenants can object if the increase exceeds the legal cap or the WWS maximum.
If the Tenant Objects
Tenants in social and mid-market segments can engage the Rent Tribunal (Huurcommissie) for independent adjudication. In the free sector, disputes generally go to the subdistrict court.
