What is the CPI limit for rent increases in Leiden?
The CPI limit restricts rent increases for residential tenants in Leiden and throughout the Netherlands. The CPI measures inflation and is published by the Statistics Netherlands (CBS). Landlords may not increase the rent by more than the CPI increase from the previous year plus 1 percentage point.
This limit applies to regular residential rentals, but not to:
- Private sector dwellings without housing benefit
- Commercial spaces
- Temporary contracts shorter than 1 year
- Fixed rents set by housing associations
In Leiden, with high rental prices, the temporary measure since 2023 protects tenants: maximum 3.5% increase including CPI, to prevent excesses during the housing crisis.
Legal basis of the CPI limit
Laid down in the Act on Rent Increases for Residential Tenancies (WHW) and Act on Maximum Rent Increase (WMHH). Key articles:
- Art. 7:139 DCC: General conditions for rent increases.
- Art. 7:140 DCC: Maximum CPI + 1%; temporarily adjusted since 2023.
- Decree on Maximum Rent Increase (BMHH): Annual percentage.
CBS publishes CPI in January. Example: CPI increase 2023 of 5% means 6% increase in 2024, but limited to 3.5% by temporary rule. In Leiden, disputes are handled by the District Court The Hague, Location Leiden.
Tip for Leiden: Contract clauses exceeding the limit are invalid.
