CPV code 70220000 designates Non-residential property renting or leasing services in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
70220000 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 70200000 (Renting or leasing services of own property).
