Greek Property Check

TRANSPARENCY

Data sources and methodology

Greek Property Check is a pre-check, not due diligence. This page lists every public dataset our Core and Extended reports use today: who publishes it, what it can show for the parcel you confirm, and where it stops. Each report also names the sources behind every finding.

How a report is produced

  1. 01You find the property on the map and confirm one cadastral parcel. Its boundary, KAEK and mapped area come from our downloaded copy of the Hellenic Cadastre, dated 2 September 2026. If the parcel is not in that copy but appears in a Cadastre public exhibition (ανάρτηση), the exhibition outline is used and labelled as such. Seeing the parcel is free.
  2. 02After payment, the parcel is compared with every public dataset in your plan: four in Core, plus environmental and location context in Extended. Distances to OpenStreetMap features are measured from a reference point inside the parcel.
  3. 03Each check ends in one plain result: overlap with a mapped zone, contact with the boundary only, nearby, no match in the tested data, or source unavailable. Fixed rules produce these facts from the data, and each one keeps its source, evidence and limitations.
  4. 04Findings describe what public geospatial data suggests. They never call a property legal, safe, buildable, compliant or approved. Each finding comes with the question to ask your lawyer, civil engineer or accountant.

The datasets we use

Hellenic Cadastre parcels (operating cadastre)

Core, Extended
Publisher
Hellenic Cadastre
What it shows
The parcel you confirm: its KAEK, boundary and mapped area. Every other check in the report is run against this parcel.
Coverage
Areas where the operating cadastre is in force, published as 13 regional files. Not every property in Greece is in the operating cadastre yet.
Data version
Downloaded snapshot dated 2 September 2026
Limits
A downloaded copy, not a live query and not an official cadastral extract. It does not verify title, ownership, encumbrances, legal boundaries or building permits. Corrections made in the Cadastre after the snapshot date are not reflected. Data source: Ν.Π.Δ.Δ. ΕΛΛΗΝΙΚΟ ΚΤΗΜΑΤΟΛΟΓΙΟ.

Hellenic Cadastre public exhibition parcels (ανάρτηση)

Core, Extended
Publisher
Hellenic Cadastre
What it shows
The outline and reference of a parcel that the Cadastre has published for public review but that is not yet in the operating cadastre. The report labels it as an exhibition parcel.
Coverage
Used only when the parcel you confirm is not in the operating-cadastre snapshot but appears in an area under public exhibition.
Data version
Queried live when you confirm the parcel
Limits
An exhibition outline may still change before it enters the operating cadastre. It does not verify ownership, title or legal boundaries.

Flood hazard and flood risk maps

Core, Extended
Publisher
Ministry of Environment and Energy (YPEN)
What it shows
Whether the parcel overlaps a mapped flood hazard area or flood risk zone, or only touches its edge.
Coverage
National-scale mapping of the areas YPEN has mapped. Four layers: flood hazard and flood risk, each in a high- and a medium-probability scenario.
Data version
Copy downloaded 3 June 2026
Limits
No match does not mean the parcel cannot flood. The maps do not capture local drainage, basements, recent works or insurance terms. Ask a civil engineer to assess the specific building and plot.

Natura 2000 protected sites

Core, Extended
Publisher
Ministry of Environment and Energy (YPEN)
What it shows
Whether the parcel overlaps a mapped Natura 2000 site, or whether one is nearby.
Coverage
Natura 2000 sites in Greece (SCI and SPA designations), as published by YPEN.
Data version
Copy downloaded 3 June 2026
Limits
Mapped designations only. They do not show permit status, buffer rules, pending designations or every environmental restriction. Ask your lawyer or civil engineer what a designation means for your plans.
Official source
geoportal.ypen.gr/geonetwork/srv/eng/catalog.search#/metadata/c140c8d2-3820-4847-bfdc-1d6668d66325

Forest maps (δασικοί χάρτες)

Core, Extended
Publisher
Hellenic Cadastre
What it shows
Whether the parcel overlaps a forest-map polygon, and which classification codes it carries. Forest maps cover all land, so an overlap alone is not a forest signal: only forest-law codes raise a high-priority finding.
Coverage
Regional forest-map files for the 13 regions of Greece, as published on data.gov.gr.
Data version
Regional files dated 6 April 2026, downloaded 19–20 May 2026
Limits
The legal status of a forest map (posted, certified, under objection) is not encoded in the polygons, and a classification can be contested through official procedures. Ask your lawyer or civil engineer to check the official forest-map status.

Coverage
Active fault lines catalogued in the NOAFAULTs database for Greece.
Data version

What the report does not check

  • Title, ownership and encumbrances. These need a lawyer and a notary.
  • Building permits and legalisation. A civil engineer needs to review e-Adeies and the building file.
  • Buildability and zoning. These need confirmation from an engineer and the planning authority.
  • Short-term rental (STR / Airbnb) registration and rules. Ask an accountant and a lawyer to check AADE registration, municipal and building-rule requirements.
  • Market value, rent or yield. The report is not a price estimate or an appraisal.
  • Wildfire history. Ask an insurer or the seller about any known fire history.
  • The official seismic zone (ΕΑΚ). Extended shows only the distance to mapped active faults.
  • Archaeological and cultural-heritage restrictions.
  • Utility connections such as water, electricity and sewerage.
  • Terrain, slope and erosion.
  • Insurance pricing or eligibility.

Public geospatial data suggests where to look; it does not settle anything. When no signal was found in the tested layers, this does not prove absence of risk: a dataset can be incomplete, out of date, or mapped in less detail than a single parcel needs. If a source was unavailable when your report ran, the report says so instead of treating it as a clear result. Ask your lawyer or civil engineer to verify every point that matters to your decision.
