Greek forest maps: what they mean for a property

Greek forest maps show which land is protected by forest law. If a plot is coded as forest, building is generally not allowed and a sale needs extra paperwork. Many buyers only find out at the notary. You can check the official maps yourself before you get that far.

In short

  • Forest maps mark land that is forest, woodland or grassland protected by forest law. They settle the land's character, not who owns it.
  • A map is first posted for objections, then ratified. A ratified map can only be changed through a formal reform.
  • Building homes on forest-coded land is generally not allowed.
  • Since May 2026, selling land shown as forest-type on a ratified map is void without a Forest Directorate certificate.
  • Anyone can view the maps on the Hellenic Cadastre's viewers, but only the official certificate settles a specific plot.

What forest maps are

Forest maps (δασικοί χάρτες) outline land that is forest, woodland or grassland protected by forest law, and separate it from all other land. They are governed by Law 3889/2010, amended many times since, and the definition of forest comes from Law 998/1979. The Forest Directorates prepare them under the Ministry of Environment, and the Hellenic Cadastre publishes them.

A forest map records the character of the land, not its owner. It can still matter for ownership: the Cadastre sometimes lists the State as owner of forest-coded land, and owners then have to correct that entry.

Posted, objected, ratified

  • Posting (ανάρτηση): the draft map is published and owners can file objections (αντιρρήσεις) online.
  • Objection committees (ΕΠΕΑ): three-member committees, with a lawyer, an engineer and a forester, decide the objections.
  • Ratification (κύρωση): land with no pending objection is ratified, in part or in full. After that, the map can only be changed through a reform (αναμόρφωση), for example after a court decision or an obvious error.

By the Ministry's last published figure (December 2022), maps had been posted for 95% of the country and ratified for 90%. More than 200,000 objections were still waiting for a decision in early 2026, so a plot's status can still change.

What the map codes mean

The codes compare aerial photos from 1945 with recent photos and field checks. On the ratified-map legend:

  • Outside forest law: ΑΑ (other use in both the old and recent photos) and ΠΑ (a final characterisation act says non-forest).
  • Covered by forest law: ΔΔ (forest in both), ΔΑ (cleared forest), ΑΔ (farmland that later became forest), ΠΔ and ΠΧ (a final act says forest or grassland), ΧΧ and ΧΑ (grassland variants) and ΑΝ (declared for reforestation).

One plot can carry several codes. A plot that is partly forest can only be built on if the non-forest part alone meets the minimum plot rules.

Building and selling forest-coded land

The Greek Constitution protects forests, and building homes on forest land is generally not allowed. The interventions that forest law does allow are limited to listed purposes and need a formal approval (έγκριση επέμβασης).

Selling is possible, with the right paperwork. Under Law 5299/2026, in force since 5 May 2026, a sale of land that a ratified map shows as forest-type is void without a certificate from the Forest Directorate confirming its character. Where an objection or reform was accepted, the deed attaches that decision instead. For land outside forest law, an engineer's sworn declaration is enough. The Cadastre must refuse deeds that do not comply.

Some relief exists: farmland that became forest (ΑΔ) can be farmed again under conditions, and the non-forest part of a mixed plot can be sold on its own. A 2025 law also lets owners correct Cadastre entries that wrongly list the State as owner, without going to court, if they hold qualifying documents.

How to check a plot yourself

The Hellenic Cadastre publishes two public viewers: one for ratified maps and one for maps still under posting. Search the area, turn on the forest layer and compare it with the parcel outline. Take note of every code that touches the plot.

Treat what you see as a signal, not an answer. The viewer may not show a pending objection, a recent fire or a reforestation declaration. The official answer for a sale is the Forest Directorate certificate or the engineer's declaration.

What a public-data pre-check shows

Every Core and Extended report overlays the confirmed parcel on the published forest maps and reports which forest-map codes it touches and whether they fall under forest law or outside it. It then lists the questions to ask your lawyer or engineer about that result.

What it cannot tell you

It cannot tell you about pending objections, reforms, fires not yet on the map, or who owns the land, and it is not the Forest Directorate certificate needed for a sale.

Questions for your lawyer or engineer

  1. 01Is the parcel on a ratified map or only a posted one, and which code applies to each part of it?
  2. 02Is there a characterisation act or an objection committee decision for this land?
  3. 03Can you obtain the Forest Directorate certificate, or issue the engineer's declaration, needed for the sale?
  4. 04Does the Cadastre list the State as owner of any part, and can that be corrected?
  5. 05Does the non-forest part alone meet the minimum plot rules for building?
  6. 06Is any part declared for reforestation, including after a fire?
