Rent Price Indexation for Commercial Spaces in Delft

Rent price indexation for commercial spaces in Delft falls under Article 7:917 of the Dutch Civil Code (BW) and is based on the CPI (consumer price index). Landlords in the vibrant Delft city centre, with its mix of historic buildings and modern offices around the Technopolis, may index annually via written notice three months before the contract anniversary. The standard formula is: new rent price = old price × (new CPI / old CPI). Tenants of shops along the Oude Delft or offices at TU Delft can file an objection with the Rent Committee if the increase exceeds market conformity. For renovations in monumental commercial spaces or adjustments due to lively local market developments, such as the growth of tech startups, the ROZ model method is used. Disputes over calculations result in binding decisions. Crucial in Delft: indexation may not cause excessive increases; judges review for reasonableness, taking into account the specific real estate pressure around the Market and station. Companies with multi-year contracts in this student city plan budgets anticipating CPI fluctuations. Exceptions apply to small-scale retail along the canals. This system ensures inflation correction while protecting the interests of Delft entrepreneurs, especially amid rising operational costs due to tourism and university activities. (218 words)
