In Leiden, housing corporations such as DUWO and De Sleutels must keep social rental housing in good condition, suited to the historical and student-rich character of the city. Minor repairs (up to € 250) are the tenant's responsibility, but corporations are responsible for major maintenance such as roofs, pipes, painting, and facades – crucial in older Leiden buildings. Always report defects in writing via your corporation's online reporting system or the Loket Wonen Leiden; the statutory response time is a maximum of 14 days.
In case of non-compliance in Leiden, you can enforce rent reduction via the Huurcommissie, up to 100% in case of uninhabitability. The Good Landlordship Act obliges corporations to carry out planned maintenance, with extra attention to Leiden neighbourhoods such as Merenwijk or Professorenwijk where moisture problems often occur. Collect evidence with photos, your own inspections, and reports from the municipality of Leiden. This fits with the national allocation policy, as defects make a property unsuitable for Leiden students or families. Contact the Juridisch Loket Leiden for free advice.
