Buying property in Santorini: the one Cyclades island where a non-EU buyer needs consent before the deed

A Santorini purchase has a step that a purchase on the next island along does not, and it comes before the notary rather than after.

The short answer: Thira (Santorini) is named in Greece's border-area list, so a buyer whose nationality or seat is outside the EU and EFTA cannot acquire any real or contractual right over property there until a committee lifts the prohibition — and Thira is the only island of the Cyclades on that list. Buyers on Paros, Naxos, Milos or Mykonos are not caught by this rule at all. The committee that decides sits at the Decentralised Administration of the Aegean, takes applications on Tuesdays and Thursdays between 12:00 and 15:00, sets no fee, and works to no stated deadline. A purchase through a company does not escape the rule, and on Santorini this requirement sits on top of the €800,000 investor-permit threshold rather than instead of it.

Every rule below is cited to the instrument it comes from, with the date we read it. Where our conclusion is a reading of two instruments together rather than something either states, this page says so.

Santorini is on Greece's border-area list, and it is the only Cyclades island on it

The list is article 24(1) of Law 1892/1990, in the wording given to it by article 43(1) of Law 4278/2014. It designates, as border areas: the prefectures of the Dodecanese, Evros, Thesprotia, Kastoria, Kilkis, Lesbos, Xanthi, Preveza, Rodopi, Samos, Florina and Chios; the islands of Thira and Skyros; the former eparchies of Nevrokopi, Pogoni, Konitsa, Almopia, Edessa and Sintiki; and the former communities of Othonoi, Mathraki and Ereikoussa.

Read that list for the Cyclades and the result is unusual. The Cyclades prefecture is not designated. Thira is designated as a single island, named alongside Skyros, which is not in the Cyclades at all. So within one of the most-bought island groups in Greece, the rule applies to one island and not to its neighbours.

That is a statutory reading, and it is confirmed administratively below, which is why this page states it as a fact rather than as an inference. Article 24(2) allows a presidential decree to add or remove areas, so the list is a current state rather than a fixture — it should be re-read before a signature, not taken from an article.

The statute is at Law 1892/1990, articles 24 to 28, read article by article on 7 November 2026.

The committee's own Santorini application form names the Cyclades prefecture as the island of Thira alone

This is the part that turns a reading of a list into something a buyer can rely on.

The Decentralised Administration of the Aegean publishes the application forms for lifting the prohibition, and they are split by island group. As reissued in May 2026, there are four:

• *Αίτηση Φυσικών Προσώπων* — natural persons — «Νομός Δωδεκανήσου, Νομός Κυκλάδων (Νήσος Θήρα)»
• *Αίτηση Νομικών Προσώπων* — legal persons — same two prefectures, same parenthesis
• the same pair for «Νομός Λέσβου, Νομός Σάμου, Νομός Χίου», the North Aegean prefectures

The administration's own notice to applicants is headed the same way: the committee of article 26 for Ν. ΔΩΔΕΚΑΝΗΣΟΥ, Ν. ΚΥΚΛΑΔΩΝ (ΝΗΣΟΣ ΘΗΡΑ). In other words the regulator, when it had to write down which places its South Aegean committee covers, wrote the whole Dodecanese prefecture and, for the Cyclades, the island of Thira in brackets.

A Santorini buyer therefore files the South Aegean form. A buyer on Paros has no form to file, because there is no prohibition to lift. We read these pages on 9 November 2026; the page's own modification date is 12 May 2026, which is what establishes that the committee is operating rather than merely legislated. The committee's description of its own work is at the Decentralised Administration of the Aegean.

Who the Santorini rule binds: nationality or seat outside the EU and EFTA

The prohibition is article 25(1) of Law 1892/1990, as replaced by article 114(2) of Law 3978/2011. It forbids every act between living persons that creates a real or contractual right over immovable property in a border area in favour of natural or legal persons whose nationality or seat is outside the European Union and EFTA.

So on Santorini:

• A buyer who is a citizen of an EU or EFTA state is outside the prohibition and needs nothing from the committee.
• A buyer from a third country — the United States, the United Kingdom, Russia, China, Israel, Turkey, the Gulf states — is inside it, and needs the consent before the transaction, not after.
• Residence does not substitute for nationality. The provision speaks of nationality and seat, and holding a Greek residence permit is not named as an exemption anywhere in articles 25 to 27.

Buying Santorini property through a company does not take the purchase outside the rule

The same paragraph reaches the wrapper as well as the asset. Article 25(1) prohibits the transfer of shares or partnership interests, and the change of partners, in a company of any legal form that owns property in a border area, where the result is to put the right in the hands of a person caught by the prohibition.

That closes the structure a buyer is most often offered on Santorini: a Greek company already holding the villa, with the shares sold instead of the land. The rule follows the property, not the paperwork around it.

What a Santorini application contains, and the two things it does not have

The documents are fixed by joint ministerial decision Φ.114/497810 of 21 March 2024, published at ΦΕΚ 1893/Β of 26 March 2024. For a natural person it asks for: the application with the notarised signatures of both parties and a statement of the intended use; a curriculum vitae; a criminal record extract no older than six months; a certified copy of the passport; proof of lawful stay in the EU or EEA; a birth certificate; and a site diagram on a 1:50,000 extract. Foreign documents must be apostilled and officially translated, and beneficial owners are checked under Law 4557/2018. Article 7(2) places every cost on the applicant.

The two absences matter more than the list. The decision sets no fee — and so this site publishes no figure for one — and no deadline for the decision. The document list is at ΦΕΚ 1893/Β of 26 March 2024.

Add to that the practical window: the South Aegean secretariat receives applications, and answers questions about the progress of a case in person or by telephone, exclusively on Tuesdays and Thursdays from 12:00 to 15:00. A file that is short one document waits for the next Tuesday.

The Defence Ministry holds a veto over a Santorini consent

Under article 26 of Law 1892/1990, as replaced by article 114(3) of Law 3978/2011 with its point (a) replaced by article 43(2) of Law 4278/2014, the application goes before a committee constituted for a five-year term at each Decentralised Administration. The prohibition is lifted by a majority of the total number of members and only if the representative of the Ministry of National Defence votes in favour.

That is a veto, not a vote to be outnumbered. Article 27 allows prohibitions to be lifted in bulk by category of transaction with the Defence Minister's approval, and re-imposed at any time; whether any blanket lifting currently covers ordinary residential purchases on Thira is not established, and this page does not assume one.

On Santorini the €800,000 golden visa threshold and the border-area consent both apply

Santorini sits in the top band of the investor permit. Since 1 September 2024 the thresholds are €800,000 across Attica, the Thessaloniki regional unit, Mykonos, Thira and islands with populations above 3,100; €400,000 elsewhere; and €250,000 only by the narrow conversion and restoration exceptions.

So a third-country buyer on Santorini meets the highest price threshold in the scheme and the consent requirement. Mykonos, by contrast, is in the €800,000 band but not in the border-area list — the two maps are drawn by different statutes for different reasons, and they do not coincide.

This is our reading, not a rule either statute states. We found no exemption for investor-permit purchases in articles 25 to 27 of Law 1892/1990, and none in article 100 of Law 5038/2023. A third-country buyer is exactly the person article 25 binds. But the conclusion is a negative finding — we did not find an exemption — and negative findings are the ones a provision we have not read overturns most easily. What the permit itself asks for, zone by zone, is in the Greek residence guide.

What a Santorini purchase contract has to survive: a consent with no clock

Two timetables meet here, and neither is set by the other.

The consent has no statutory deadline. A Greek exclusive brokerage agreement, meanwhile, is capped at eight months by article 200(4) of Law 4072/2012, extendable by four months on written notice, and the default term of an ordinary brokerage contract is twelve months. A reservation or preliminary agreement typically fixes a completion date in weeks.

Our reading, not a rule: a Santorini purchase that depends on this consent should not carry a fixed completion date, a forfeitable deposit tied to one, or a penalty that starts running while the file sits with the committee. The legal obstacle is not the price or the survey; it is that nobody — not the seller, not the agent, not the committee — can tell you when the answer comes. How Greek agency contracts work, including what the broker must put in writing, is in the Greek estate agents guide.

What we could not establish about the 2026 tightening

Greek press reported through 2026 that the border-area regime was being tightened, with specific attention to schemes in the Dodecanese, a parliamentary exchange in June and statements by the defence minister about a new framework.

We could not find an enacted instrument amending articles 24 to 28. On 9 November 2026 we also searched the Decentralised Administration of the Aegean's own announcements for anything on border areas and found only civil-service transfer notices — nothing on a change to the regime it administers. So the claim is recorded as unverified on our sources page rather than dated, and the instruction on this page is to check for an amendment before signing, not to rely on a date.

What is established is that the regime is live: its document list was re-set in March 2024, its application forms were reissued in May 2026, and the committee is receiving applications now.
