Not every rent increase in Leiden falls under the point calculation system. Exceptions apply for large-scale maintenance, improvements such as insulation or a new bathroom, provided they are invoiced and approved by the municipality. Landlords may then pass on an 'improvement increase' of up to 80% of the costs, in addition to the regular indexation. In Leiden, with its historic buildings in neighbourhoods such as de Mare and Professorenwijk, we often see renovations for energy saving.
In case of mutation (new tenant) or interim agreements in the tenancy agreement, deviation is possible. Room rental in student houses around Leiden University and temporary contracts fall outside. For luxury apartments in the city centre with gross rent above €1,000, no limit sometimes applies. The Good Landlordship Act limits excesses, especially relevant with the strict enforcement by the Leiden Rent Team.
Tenants must give written consent for additional increases. In case of dispute, the district court judge rules in the Palace of Justice on Lange Voort. Example: installing solar panels on roofs in the City Centre justifies 5% extra. In 2024, the government caps increases at 5.3% for private sector homes under €1,100, while Leiden housing associations such as Haag Wonen and Welgelegen strictly monitor. Always check your tenancy agreement for clauses and consult the Juridisch Loket in Breestraat for free advice. Local help via the Rent Consultation Hour at the Town Hall prevents nasty surprises.
