Rent Reduction After Completion of Renovation Works in Delft

After completion of a complex-wide renovation under the 70% scheme in Delft, tenants are entitled to rent reduction if the works result in devaluation or defects, as often seen in older TU neighbourhoods or historical complexes around the Markt. Article 7:243 BW provides that judicial review of the quality improvement may result in adjustment of the rent price. In Delft, where the municipality imposes strict requirements on renovations in monumental buildings, you can demand reduction up to 40% of the investment costs for insufficient EPC improvements or failing energy savings. The Huurcommissie calculates this based on the 'housing valuation table', taking into account local factors such as the high humidity along the Schie. Practical examples from Delft show that for leaks after renovation in Populair dwellings or inferior insulation in Agnietenbuurt complexes, successful claims lead to 10-25% reductions. Tenants must submit measurements from certified inspectors and proceed with the Huurcommissie in The Hague within a reasonable term. Landlords risk fines via the Municipality of Delft for non-compliance. Combine this with the Wet goed verhuurderschap and local consultation rounds for extra pressure on housing associations such as Vestia. (218 words)
