Picture a couple from Surrey who find a stone house in the Corfu hills, olive terraces below, sea view to Albania. At home they would not buy a two-bedroom terrace without a building survey before exchange. In Greece, nobody suggests one, the process rolls politely toward the notary, and the silence reads as reassurance. It is not. The Ionian Islands are the most seismically active corner of Greece and the wettest, and the local transaction chain will let a British buyer complete on a house nobody has assessed, in earthquake country, without a word of warning.

This is the specific gap our Ionian Islands property inspection page exists to close: an independent, buyer-side property inspection of the kind British buyers already understand, carried out by an advisor who only ever works for the buyer. What follows is what that inspection is looking for in this particular archipelago.

Earthquake Country, Two Different Histories

The southern Ionian, Kefalonia, Zakynthos, Lefkada and Ithaca, sits in Greece’s highest seismic hazard zone. The 1953 Ionian earthquake destroyed most of the building stock on Kefalonia and Zakynthos, which means much of what stands there today is post-1953 reconstruction of very uneven quality, tested again as recently as the 2014 Kefalonia earthquakes. Corfu is less exposed than the central Ionian islands and retains far more of its Venetian fabric, but less exposed does not mean low risk. Two dates matter everywhere in the archipelago: whether the building predates the modern seismic code era that began taking shape in 1985, and whether anything structural has been altered since. A charming 1960s villa with a later floor added on top is a different asset from the one in the photographs, and only a structural assessment against the permit file reveals which one is for sale.

The Wettest Corner of a Dry Country

British buyers arrive braced for damp at home and assume the Mediterranean absolves them. The Ionian is the exception: Corfu is the wettest of the Greek islands, with well over a meter of rain a year, concentrated in autumn and winter when owners are absent. Stone walls wick moisture from the ground, closed-up houses cannot dry out, flat roofs and terraces pond, and by spring the mold has been painted over for the viewing season. Damp in the Ionian behaves like damp in Devon, and it should be inspected with exactly the same suspicion, along with the drainage around the house, because hillside plots shed winter water through whatever stands in the way.

BEFORE YOU COMMIT TO A PROPERTY IN THE IONIAN ISLANDS

Send the listing, floor plans, permit documents or agent material before signing anything.

We perform remote asset reviews for British and international buyers evaluating properties on Corfu, Kefalonia, Zakynthos, Lefkada and the smaller Ionian islands.

This early-stage review identifies: pre-1985 structures needing seismic assessment, indicators of moisture and drainage exposure, inconsistencies between the permit file and the marketed property, and unpermitted additions likely to need regularization before transfer.

The review is independent, English-language and delivered directly to the buyer.

Old Stone, Long Inheritances, Short Paperwork

The rural Ionian property that British buyers love, the stone farmhouse in the olives, tends to carry the archipelago’s other classic risk: a multi-generational ownership history. Houses extended informally across decades, boundaries that exist in family memory rather than in the cadaster, and outbuildings that appear on no drawing. Under Greece’s regularization rules, originally Law 4495/2017 and since June 2026 codified in the Spatial Planning and Urban Planning Code (Law 5306/2026), unpermitted works must be regularized before transfer. For eligible Category 1 to 4 violations completed by 28 July 2011, the filing deadline runs to 31 March 2028 under Law 5270/2026, and whatever remains unsettled becomes the buyer’s problem. On Corfu, heritage protections in and around the old town add a further layer: what may be altered, and at what cost, is a question to answer before purchase, not after. None of this rules a property out. Inheritance chains resolve, boundaries get surveyed and violations get regularized every week in the Ionian, but each carries a cost and a timeline, and both belong in the negotiation rather than in the first winter of ownership.

The Conveyancing Gap Nobody Mentions

In England and Wales, the survey happens because the buyer commissions one before exchange; it was never the seller’s or the solicitor’s job. Greece is the same, minus the habit. The notary certifies the contract, the lawyer checks the title, the seller’s engineer certifies permit compliance from documents, and the building itself is nobody’s brief, a structure we unpack in our guide to building surveys and their cost in Greece. Nothing prevents making an offer subject to a satisfactory survey with a named independent firm. The habit that protects a buyer in Guildford protects the same buyer in Gaios.

What an Ionian Inspection Prioritizes

The scope follows the geography. Structural assessment against seismic exposure, with particular attention to pre-1985 construction and later alterations. Moisture, drainage and roof condition, inspected as seriously as they would be in the UK. The permit file measured against the physical building, with regularization status confirmed rather than assumed. And the installations, because island water and power systems age faster than their mainland cousins. The findings land before the preliminary contract, where they are still a price adjustment rather than a dispute, the difference explained in our guide to the risks of buying property in Greece.

Buying in Corfu, Kefalonia or Zakynthos?

Before contracts are signed, we review: structural condition against Ionian seismic exposure, moisture and drainage behavior, the permit file against the built reality, and regularization exposure under the current planning code.

For British and international buyers acquiring property in the Ionian Islands, we provide independent property inspections, building surveys and remote asset reviews, delivered in English directly to the buyer, typically within 7 working days.

Frequently Asked Questions

Are the Ionian Islands in an earthquake zone?

Yes. Kefalonia, Zakynthos, Lefkada and Ithaca sit in Greece’s highest seismic hazard zone, and the 1953 Ionian earthquake destroyed most of the older stock on Kefalonia and Zakynthos. Corfu is less exposed and retains far more pre-war building fabric. The construction date and any later structural alterations decide how a specific building should be assessed.

Do I need a survey when buying property in Corfu?

Greek law does not require one, and nobody in the standard transaction will suggest one, but that is a gap rather than a signal. A buyer can make an offer subject to a satisfactory building survey by a named independent firm, exactly as at home.

How much does a building survey cost in the Ionian Islands?

A property inspection from an independent technical advisor starts from 5,000 euros, scoped to the size, type and location of the property. Set against remediation of a single serious structural or moisture defect, or an unresolved regularization case inherited at transfer, it is the smaller figure in every scenario in which it matters.

Is damp really a problem in Greek island properties?

In the Ionian, yes. Corfu is the wettest of the Greek islands, and its rain is concentrated in the months when holiday homes stand closed. Stone walls wick ground moisture, terraces and flat roofs pond, and cosmetic redecoration before the viewing season hides the evidence. Moisture should be inspected as seriously as it would be in the UK.
