# Earthquakes, insurance and the building code: the honest seismic picture for a home in Crete > Crete moves. Two magnitude-6 earthquakes in one autumn in 2021, a building code that changed in 1959, 1985, 1995 and 2000, houses built under each of them, and an insurance market that most Greeks ignore. What the year on the permit means, what cover costs, and the ENFIA discount that makes insuring a home cheaper than not. - Canonical URL: https://honestcrete.com/buying/earthquakes-insurance-building-code-crete/ - Author: Fotis (Honest Crete, Heraklion) - Section: Buying property in Crete · Stage: Risks - Rules verified: August 2026 · Updated: 2026-08-22 · Published: 2026-08-22 - How to cite: "Honest Crete — Earthquakes, insurance and the building code: the honest seismic picture for a home in Crete (rules verified August 2026), https://honestcrete.com/buying/earthquakes-insurance-building-code-crete/" - Disclosure: Honest Crete does not sell or list property and nobody here is an estate agent.

Both were felt across the island, Heraklion included. Nothing about either was unusual for this island; what was unusual was that they happened in a year when foreigners were buying here in numbers, and most of them had not thought about it. This is the article about the thing nobody puts in a listing. I am not an engineer; the codes and the numbers below are the public record, verified in August 2026, and the judgments are the ones engineers here actually make. **The seismic picture in one minute.** Crete sits on the most active plate boundary in Europe and will have strong earthquakes again. Greek buildings were designed to four successive codes — 1959, 1985, 1995 and 2000, now aligned with the European standard — and the year on the permit tells you which. A post-2000 concrete house is designed for it; a pre-1985 one was designed for less; a stone house was designed for nothing and has survived anyway, with a history in its cracks. Insurance against earthquake, fire and flood costs a few hundred euros a year on an ordinary house and earns a 20% discount on the annual property tax for homes up to €500,000 in taxable value. Insure the rebuild value, and have an engineer read the walls first. ## Where the island sits South of Crete the African plate is sliding under the Aegean, and the island is the crumpled edge of that collision. The great earthquake of 365 AD lifted the west of the island by several metres — you can see the old shoreline as a pale band on the cliffs near Chania — and 1810 and 1856 were catastrophic for Heraklion. The 2021 events were not the big ones; the Arkalochori shock was a shallow local fault letting go, the Lasithi one an offshore rupture, and the island's faults are reckoned capable of magnitude seven. None of this is a reason not to live here; a third of a million people do, and have for five thousand years. It is a reason to know what your house was built to do. ## The four codes, and what the year means Greece first required seismic design in 1959, after the Ionian earthquakes of 1953. The code was substantially strengthened in 1985, after the Thessaloniki and Corinth earthquakes, and again in 1995 after Athens' suburbs shook; the current framework, EAK 2000, followed, with its hazard map revised in 2003 and the whole thing since harmonised with Eurocode 8. Crete sits in the middle and upper design zones of that map, with design accelerations in the range the code sets for the most exposed parts of the country. For a buyer the practical reading is by date. A reinforced-concrete house permitted after 2000 was designed for ground motion of the order that the Arkalochori shock delivered to Heraklion, and the houses of that generation around the epicentre mostly came through with cracked plaster. A house from the 1960s to the early 1980s was designed to a far lighter standard and is the category engineers look at hardest: a concrete frame with the ground floor open for parking or a shop, a "soft storey", is the classic weakness. Anything earlier — the stone and lime-mortar houses of the villages — was built to no code at all, by masons who knew the ground and built thick, low and heavy. Many have stood through two centuries of shaking; all carry it in their walls; some have been quietly strengthened with concrete ties and some have not. The year on the permit, and what the walls say, is a job for the [engineer's check](https://honestcrete.com/buying/building-survey-engineer-check-crete/) before the deposit, and the cracks that worry an engineer are not the ones that worry a buyer. ## What the earthquake does to a purchase Three things. It makes the permit year a structural fact rather than a date. It makes the [illegal extension](https://honestcrete.com/buying/illegal-constructions-afthaireta-crete/) — the extra floor the permit never saw, the closed-in pilotis — a structural question as well as a legal one, because unplanned mass on a frame is what the codes exist to prevent. And it makes the insurance question, which most Greeks answer by not asking, the one thing on this page you can fix with a phone call. ## Insurance, and why it is now cheaper than not insuring Greek homeowners have historically not insured. Most houses on the island carry no cover beyond the mortgage bank's requirement, and after 2021 the state paid for the repairs in the villages because nobody else was going to. That has begun to change from the tax side: since 2024 a home insured against earthquake, fire and flood has earned a discount on ENFIA, the annual property tax, and from 2025 the discount is 20% for properties with a taxable value up to €500,000, provided the policy covers the full value of the building and ran for at least three months of the previous year. It is claimed by declaring the policy through the tax authority's property platform, and the insurers have learned to issue the certificate the platform wants. The arithmetic on an ordinary Cretan house is simple. A policy covering earthquake, fire and flood for the rebuild value runs to a few hundred euros a year — more for a large villa, more for older construction, more on the coast — and the ENFIA discount returns a meaningful part of that. Insure the rebuild value, not the purchase price: the land is not going anywhere, and the house is what the policy has to put back. The [article on running costs](https://honestcrete.com/buying/running-costs-of-a-home-in-crete/) puts the premium and the tax side by side. ## Living with it Bolt the water heater. Know where the gas valve is. Keep the cistern full. Do not put the bed under the thing on the wall. Listen to the locals, who have a relaxed and entirely correct attitude: the ground moves, the good houses hold, and a magnitude five on a Tuesday afternoon is a conversation, not an event. The Arkalochori shock was different in kind — shallow, close, violent — and the lesson of it was the one above: the houses that were designed for it behaved as designed, and the ones that were not did not. ## The honest downside You are buying on a plate boundary and no amount of paperwork changes the geology. The codes protect the buildings built under them and say nothing about the ones built before, which is most of the charming stock. The insurance market is thin, the small print on earthquake cover matters — excesses, the definition of an event, the rebuild value you declared — and a claim after a regional disaster is slow. And the house on the hill with the view is usually on the hill because the ground there is rock, which is good, and the house on the flat near the river is on the flat because the ground is soft, which is not. Ask the engineer about the ground as well as the walls. *Disclosure:* Disclosure: Honest Crete does not sell or list property. Enquiries sent from this section go to a licensed estate agent, not to us; the full statement is below. Nothing in this article names a developer, a property or a professional, and it never will. **The verdict.** **Worth it if** an engineer has read the permit year and the walls, and you insure the rebuild value from the day of the deed — with the tax discount it is the cheapest peace of mind on the island. **Skip it if** the plan is to own a pre-1985 concrete building with a closed-in ground floor and no cover; that is the one combination the island has already tested. ## Quick answers **Is Crete at risk of earthquakes?** Yes, seriously and permanently. The island sits on the Hellenic arc where the African plate dives under Europe; it has produced the largest earthquakes in Greek history and in 2021 had two of magnitude 6 in one autumn, one of which killed a man and damaged thousands of houses around Arkalochori. Any home here should be assumed to have felt strong shaking and to be going to feel it again. **Are houses in Crete built to withstand earthquakes?** The ones built under the modern codes are designed to. Greece introduced seismic design in 1959, strengthened it materially in 1985 and 1995, and adopted the current framework in 2000, harmonised with the European code since. A reinforced-concrete house from 2005 and a stone house from 1905 sit on the same fault and behave very differently on it. The year on the permit is a structural fact. **How much does earthquake insurance cost in Greece?** Less than people assume. A standard home policy covering earthquake, fire and flood for an ordinary house in Crete runs to a few hundred euros a year, rising with the rebuild value, the construction type and the age. Since 2024 the state has subsidised it in effect: an insured home gets a discount on its annual property tax. **What is the ENFIA discount for insured homes?** A 20% reduction in the annual property tax for a home insured against earthquake, fire and flood for its full building value, for at least three months of the previous year, where the property's taxable value is up to €500,000; the discount was doubled from 10% in 2025. It is claimed by declaring the policy through the tax authority's property platform. On many homes it pays a large part of the premium. **Should I avoid old buildings because of earthquakes?** No, but you should know what you are buying. Old stone houses have survived two centuries of shaking, which is both a recommendation and a warning: their walls carry the history in cracks an engineer can read. Many have been strengthened; some have not. The pre-purchase engineer's check is where you find out, and the rebuild-value insurance is how you sleep. **What about tsunamis?** A real but rare risk on Crete's coasts, recorded in history and, in a very minor way, in 2021. It is one more reason the shoreline lines keep buildings back from the water, and one reason a house on the hill above the beach is not only cheaper than one on it.
