The landlord is responsible for major maintenance (roof, foundation) and installations, based on art. 7:206 BW. Tenants maintain minor defects (paint, locks). For point-based rent increase, the property must be in good condition; defects justify reduction.
Report defects in writing; landlord has two months to repair. Otherwise, rent reduction or self-repair with reimbursement. Minor repair fund: tenant pays up to €100 per year. In case of neglect, the court may impose rent reduction. Example: leakage due to poor roof gives 20% discount. Rent teams inspect. Document everything for disputes. (198 words)
