Quick answer: Greece Golden Visa property at the €400,000 or €800,000 tier must measure at least 120m² of main usable area on a single title deed (Law 5100/2024). Balconies, terraces, parking and storage do not count. Only the €250,000 heritage restoration route skips the size rule. A licensed engineer certifies the area before you apply, not the broker brochure. See how the rule works in practice on Crete €400K property and the step-by-step Golden Visa due diligence checklist.

What Law 5100/2024 Actually Says
Greece restructured its Golden Visa programme with Law 5100/2024, raising investment thresholds and introducing a minimum property size that did not exist before. The full Greece Golden Visa property guide for 2026 covers the complete framework, but the 120m² rule is the most misunderstood element of the reform. Screen candidates against the Golden Visa eligible projects directory before you pay a reservation deposit.
- Terraces and balconies, regardless of how large they are
- Parking spaces, whether open or enclosed in a garage
- Storage rooms and utility areas attached to the unit
- Basement areas not recorded as habitable space in the building permit
- Communal stairs, landings, or shared facilities
A property listed as “135m² total” in a developer brochure may contain only 108m² of main usable area once these exclusions are applied. Buyers who rely on marketing figures without checking the Electronic Building Identity risk purchasing a property that fails the Golden Visa test at the application stage, after the purchase has already completed.
How the Tiers Work With the Size Rule
| Tier | Minimum Investment | Minimum Main Usable Area | Applicable Zones |
|---|---|---|---|
| Standard residential | €400,000 | 120m² on one deed | Most of Greece |
| High-demand residential | €800,000 | 120m² on one deed | Athens, Thessaloniki, Mykonos, Santorini |
| Heritage restoration | €250,000 | No minimum size | Designated protected buildings only |
| Commercial-to-residential | €400,000 | 120m² after conversion | All zones |
The detailed breakdown of Golden Visa investment tiers and zone maps identifies which municipalities fall inside the €800K zone. For most island and mainland locations outside those four high-demand areas, the €400K tier applies, along with the 120m² requirement.

The Single Title Deed Condition
Purchasing two adjacent apartments, each 70m², and registering them as separate properties does not satisfy the law, even if a wall is physically removed to combine them. Greek property law looks at the legal property record, not the built configuration. Two deeds equal two properties, regardless of how they are used.
Buyers who want to aggregate smaller units must complete a legal property merger (συνένωση) before finalising the purchase. This process involves:
- Architectural drawings confirming the structural viability of the merger
- Approval from the relevant urban planning authority
- Issuance of a new unified building permit and building identity
- Registration of the merged property as a single title at the Land Registry
A merger adds roughly three to four months to a transaction timeline and carries its own professional fees and registration costs. The full breakdown of buying costs in Greece helps investors budget accurately before committing to a multi-unit acquisition strategy.
Who Certifies the Area and How
Greek property transactions require a licensed civil engineer or architect to certify the main usable area. The certification takes the form of the Electronic Building Identity (Ηλεκτρονική Ταυτότητα Κτιρίου), a national registry record that lists every legally recognised area of a property by room category.
The Ministry of Migration reviews the Electronic Building Identity, not the estate agent brochure, when assessing a Golden Visa application. The figure in the Identity is the figure that counts.
| Document | Prepared By | Role in Application |
|---|---|---|
| Electronic Building Identity | Licensed engineer | Records legal area by room type |
| Topographic survey | Licensed civil engineer | Confirms plot boundaries and built footprint |
| Building conformity certificate | Licensed architect or engineer | Confirms building matches permit |
| Notarial purchase contract | Notary | Records legal ownership and property description |
Where a property’s building permit predates the electronic identity system, an engineer must prepare a new conformity certificate. Older buildings in Athens, Thessaloniki, and on the islands frequently have discrepancies between the original permit and the actual built space. These must be regularised before the property qualifies as a Golden Visa investment. Regularisation timelines range from two months for minor issues to over a year for significant unauthorised construction.
Properties That Clear the 120m² Bar Most Easily
The size requirement effectively removes the small-format studio and one-bedroom apartment market from Golden Visa consideration. These properties dominated early-era transactions when no size rule existed. Properties most likely to meet the threshold include:
- Two-bedroom and three-bedroom apartments in Athens, Thessaloniki, and coastal cities
- Sea-view villas and detached houses on the islands and Peloponnese
- Maisonette apartments in Athens’ northern and southern suburbs
- New-build developments specifically structured for the Golden Visa market
- Large commercial spaces being converted to residential use in city centres
Buying property in Greece as a foreign national confirms that non-EU buyers face no ownership restrictions beyond the standard investment threshold. Freehold title is available to any investor, and there are no limitations on the type of property that can be purchased beyond what the Golden Visa law specifies.
Where the rule is easy and where it is hard follows directly from price per square metre. In Kalamata at €1,600 to €2,100 per square metre, the €400,000 threshold buys 190 to 250 square metres and the rule is a formality. In Heraklion at €1,800 to €2,200 it buys 182 to 222. In Apokoronas villages at €1,900 to €2,400 it buys 167 to 210. The rule bites at the top of the market: Mykonos Town at €6,500 to €8,500 per square metre gives only 94 to 123 square metres at the €800,000 threshold, and ultra-prime seafront above €8,500 usually falls below 120 altogether. Kolonaki at roughly €7,270 gives about 110. The general pattern is that the €400,000 tier almost never fails on size and the €800,000 tier frequently does, which inverts the intuition that a larger budget buys a larger property.
The Heritage Restoration Exception in Detail
The only residential Golden Visa route exempt from the 120m² rule is the heritage restoration tier at €250,000. This applies to properties listed in Greece’s official register of protected buildings (διατηρητέα κτίρια) that require comprehensive restoration.
The trade-offs are significant compared to a standard residential purchase:
- The building must carry an official protected status, older buildings without that designation do not qualify
- The full €250,000 must represent restoration expenditure, not property acquisition cost
- A restoration plan must receive approval from the Central Archaeological Council before work begins
- The restored property cannot be used commercially for five years after completion
For investors whose primary goal is Golden Visa residency rather than heritage preservation, the operational complexity of this route generally makes the €400,000 residential purchase more practical, despite the higher investment level and the 120m² requirement.
What the Size Rule Means for Rental Returns
Properties at 120m² and above in the same neighbourhoods typically achieve slightly lower gross yield on a per-square-metre basis, but higher absolute rental income. Short-term rental platforms have partially offset this dynamic: a three-bedroom apartment of 130m² in Glyfada, Kifissia, or Neo Psychiko can reach nightly rates that support annual gross yields in a competitive range when occupancy runs above 70 percent. Actual performance depends on location, management quality, platform fees, and seasonal demand, no specific return figure is guaranteed by the investment itself.
The broader Greece property investment framework covers the tax treatment of rental income for non-resident investors, including the flat-rate tax regime available under certain conditions.
Crete, the Islands, and the 120m² Rule
Outside the four high-demand zones the area rule stops being the binding constraint. Crete, Rhodes, Corfu and most Aegean islands sit in the €400,000 tier, and at regional pricing of roughly €1,800 to €2,400 per square metre that budget buys 165 to 220 square metres. The 120 m² minimum applies identically, but it is met with 45 to 100 square metres of margin rather than being the thing that decides the purchase. Crete, Rhodes, Corfu, and most Aegean islands fall outside the four high-demand zones. The €400,000 investment threshold and 120m² requirement apply across these locations.
Island property markets have strong existing demand for larger villas and sea-view apartments, many of which already exceed 120m² of main usable area. The threshold is easier to meet in these markets than in compact urban centres where apartments trend smaller.
Crete Golden Visa property at the €400,000 level typically offers more built area per euro than Athens central, which makes the size requirement a practical non-issue for buyers targeting the island. A well-specified two-bedroom villa in eastern Crete will usually reach 130 to 160m² of main usable area. Before you wire a deposit, walk the file through the Golden Visa due diligence checklist.
Santorini and Mykonos sit inside the high-demand zone, so the €800,000 threshold applies there, still with the 120m² minimum.
Pre-Purchase Checklist: The Six Checks That Matter
| Check | How to Verify | Risk if Skipped |
|---|---|---|
| Main usable area is at least 120m² | Electronic Building Identity from seller | Property fails Golden Visa test post-purchase |
| Area exists on a single title deed | Land Registry extract | Application rejected if area split across deeds |
| No regularisation works pending | Building conformity certificate | Delays of six to eighteen months to regularise |
| Certified area matches marketing description | Independent engineer survey | Shortfall discovered only at application stage |
| Purchase price meets tier threshold | Notarial contract value | Application invalid if below required minimum |
| No encumbrances or prior Golden Visa restrictions | Land Registry search | Ownership dispute or title defect after purchase |
Engaging an independent lawyer and a licensed engineer before signing a preliminary contract (προσύμφωνο) is standard practice in Greek property transactions. Professional fees and surveys represent a small fraction of the acquisition cost and can prevent the total loss of the investment if a fundamental problem emerges with the property record.
Reconciling the 120m² Rule on a Split-Level Maisonette
Split-level and maisonette layouts are where the rule bites hardest, because the marketing figure and the certified figure diverge most. The Electronic Building Identity and the engineer’s survey break the property into countable and non-countable space, and mezzanines, non-habitable attics, basements without residential permit classification and enclosed-but-unpermitted verandas all fall on the wrong side. The breakdown below shows how a property presented as comfortably over 120 m² can certify under it. Upon closer inspection of the engineering survey and the Electronic Building Identity (Ηλεκτρονική Ταυτότητα Κτιρίου), the actual breakdown of the spaces was as follows:
| Space | Marketed area | Counts toward the 120 m² rule? |
|---|---|---|
| Main living areas across both levels | 112 m² | Yes: κύρια χρήση on the permit |
| Basement playroom, enclosed and regularised | 18 m² | No: auxiliary space (βοηθητικός χώρος) |
| Balconies and terraces | 22 m² | No, never countable, whatever the view |
| Covered parking space | 12 m² | No: ancillary, not habitable |
| Marketed total | 164 m² | n/a |
| Certified main usable area | 112 m² | Fails at 8 m² short |
Under the strict guidelines of Circular 1/2026 and Law 5100/2024, the Ministry of Migration only counts the main habitable usable area (κύρια χρήση) recorded on the building permit and the Electronic Building Identity.
- The 22m² of balconies and the 12m² parking space are immediately excluded.
- The 18m² basement playroom, despite being enclosed and regularised, is legally classified as auxiliary space (βοηθητικός χώρος) rather than main living space.
Consequently, the qualifying area for this property is only 112m². Despite the purchase price exceeding the €800,000 threshold, this property fails the 120m² rule and cannot qualify for the Golden Visa. To resolve this, the buyer had to legally merge an adjacent 15m² ground-floor studio on a single title deed, raising the main usable area to 127m² before final deed registration.
Strict Verification Protocol for the 120m² Minimum
- Request the Electronic Building Identity (Ηλεκτρονική Ταυτότητα Κτιρίου): This is the ultimate source of truth. Your independent civil engineer must verify that the area listed under “Main Use” (Κύρια Χρήση) is at least 120.00m². Do not rely on the land registry (Ktimatologio) or tax registry (E9) declarations, as these can contain historical rounding errors or include auxiliary spaces.
- Title Deed Consolidation Check: The 120m² must exist on a single property title deed. If you are buying an apartment that is 110m² and a separate storage room of 15m² on the same floor, they do not qualify unless they are legally merged into a single horizontal property (οριζόντια ιδιοκτησία) with a single registration number at the Land Registry.
- Conformity Certificate (Πιστοποιητικό Συμβατότητας): Ensure the engineer issues a formal certificate confirming that the physical layout matches the approved architectural plans and that there are no regularisation issues (τακτοποίηση αυθαιρέτων) pending. Any unregularised planning violations will block the Golden Visa application.
Co-Ownership and Multiple Applicants under the 120m² Rule
Co-ownership does not divide the area test. The 120 m² of main usable area is measured on the property, not per owner, so two spouses buying one qualifying apartment together satisfy the rule once, on one deed. What co-ownership does change is the investment threshold: each applicant seeking an independent permit must meet the full €400,000 or €800,000 figure in their own right, so an €800,000 Attica apartment split between two unrelated buyers gives neither of them a qualifying investment. Spouses and dependent children are handled instead as one family application on a single investment. Structure this with your lawyer before the preliminary agreement, because the deed wording is what the Ministry reads.
Buyer scenarios
The 120 m² rule disqualifies more properties than the price threshold does, and it does so late, after an offer is made and an engineer is instructed. The three cases below are the ones that recur: the apartment that certifies just short, the two adjoining titles that cannot be added together, and the terrace-heavy Riviera flat whose marketed area is mostly outdoors. The area rule decides more purchases than the price threshold does. Three situations come up repeatedly.
The buyer who found the perfect apartment at 118 m². There is no rounding and no discretion. If the engineer certifies main usable area below 120 m², the property fails regardless of price, condition or location. The only routes are a different property, or the €250,000 heritage restoration and conversion route, which is exempt from the area rule entirely.
The buyer offered two adjoining apartments. Two title deeds do not combine, however physically adjacent the units are. A legal merger into a single property with one deed is possible, but it must be completed and registered before the Golden Visa application, not promised as a post-completion step. Budget engineer, notary and registry time for the merger and confirm the merged unit still holds a residential permit classification.
The buyer relying on a marketing floor plan. Listings routinely quote gross built area including open balconies, parking and storage. A “145 m²” apartment can certify at 112 m². Commission the engineer certificate before the reservation deposit rather than after, because that document, not the brochure, is what the Ministry of Migration reads.
Frequently Asked Questions
Under Law 5100/2024, any residential property purchased for the €400,000 or €800,000 Golden Visa tiers must have a minimum main usable area of 120 square metres. Terraces, balconies, parking spaces, and storage rooms are excluded from the measurement.
No. The 120m² minimum applies only to the €400,000 and €800,000 residential tiers under Law 5100/2024. The €250,000 heritage restoration route is exempt from the size requirement and is the only residential Golden Visa option without a minimum property size.
No. The law requires a single property on one title deed with at least 120m² of main usable area. Two separate deeds do not qualify, even if the units are physically combined. A legal property merger must be completed and registered before the purchase completes.
Only the enclosed main living area counts, bedrooms, living rooms, kitchens, bathrooms, and internal hallways within the building envelope. Terraces, balconies, parking spaces, storage rooms, and communal areas are explicitly excluded by Law 5100/2024.
Only through the €250,000 heritage restoration tier, which carries no minimum size. Every other residential property route under Law 5100/2024 requires the 120m² minimum on a single title deed.
Law 5100/2024 passed the Greek Parliament and entered into force in 2024. Properties purchased before the law under the previous framework are grandfathered and are not subject to the new size requirement.
A licensed Greek civil engineer or architect prepares the Electronic Building Identity and a conformity certificate confirming the main usable area. The Ministry of Migration reviews this document, not the estate agent brochure, when assessing the application.
Yes. A commercial space converted to residential use for Golden Visa purposes must reach 120m² of main usable area after conversion. The rule applies to the completed residential footprint as recorded in the new building identity.
