Greece is preparing a Unified Property Hub (Ενιαίος Κόμβος Ακινήτων) that will bring tax, cadastre, planning and municipal records for each property into one system, Greek media reported on 29 September 2026. The project budget is about €3.7 million.
The hub is not live yet. But the problem it is meant to solve is one every buyer meets today: the same property described differently by different authorities.
What changed
The contracting authority is the Ministry of Digital Governance, the budget is €3,720,000 and proposals are due by 30 November 2026. The hub will draw on:
- the tax authority’s property registry (MIDA), for tax data, leases and use;
- the Hellenic Cadastre (Κτηματολόγιο), for legal and geometric data and plot boundaries;
- planning services, for building permits, building terms and the Building Identity Certificate;
- the Ministry of Environment and Energy, for forest maps and energy performance certificates;
- the electricity network operator DEDDIE and local authorities, for supply data and the square metres used for municipal charges.
Earlier delays came from links between systems with different designs, including discrepancies in square metres and ownership details between cadastre and tax records, according to the reports. The Hellenic Data Protection Authority reviewed the plan in Opinion No. 10 of 24 August 2026 and, according to the reports, asked for clearer rules on data categories and retention periods. A draft law will govern the hub; no launch date has been published.
Separately, the Cadastre opened a digital procedure on 18 September for correcting boundaries, area and location. Cadastre president Thanos Lipas said that owners work through a licensed surveyor, with initial decisions due within 10 days and appeals within 30 days.
What to do
- Collect every record of the property’s size. Ask for the title deed, the cadastre extract, the seller’s property tax return (E9), the building permit and plans, and a recent electricity bill showing the square metres charged.
- Compare the figures line by line. Area, floor, use and ownership share should match across all documents.
- Check the cadastre code (KAEK). Confirm it matches the deed and the property you are viewing.
- Ask an engineer to compare the property with its permit. Planning records, including the Building Identity Certificate, are among the sources the hub will link.
- Check the energy performance certificate and the forest map. Both sources will feed the hub.
- If anything differs, ask the seller to correct it before the final contract. The new cadastre procedure for geometric errors runs online through a surveyor.
- If the property is let, check that the lease is declared to the tax authority. Leases are among the data the hub will link.
What to check before you sign
- One area figure appears across the deed, cadastre, E9, permit and utility bills, or the differences are explained in writing.
- Any correction request filed with the Cadastre has been decided, not only submitted.
- The use recorded on the permit matches how the property is used.
- The contract states who pays for corrections that appear after signing.
- The lease, if any, is registered and matches the rent you have been told.
Buyers should confirm how this applies to them with a Greek lawyer or accountant.
