Looking at the changes in social real estate, and school buildings in particular, the consequences of decentralisation (2015) are still visible. These days, it is no longer the municipality but the school board which is responsible for maintaining the interior and exterior of the building(s). This decentralisation wave has suddenly added an additional cost item to schools' available budgets. It would be very tempting not to invest annually in the maintenance of these buildings; however, putting this expenditure off increases the risks for users and results in higher costs. Therefore, in order to avoid large-scale repairs, maintain the value of the building and keep costs under control, it would be wise to draw up a multi-year maintenance plan.
