House Inspection Greece: What the US Model Does Not Cover and What You Need Instead

An American buyer purchases an apartment in Athens. The legal process is clean: title confirmed, tax numbers obtained, notarial deed signed. Six months later, the municipality issues a notice. The rooftop terrace enclosure added by a previous owner in 2009 was never permitted. Regularisation cost: €34,000 minimum, before fines. The Technical Diagnostic File said nothing. The lawyer found nothing. No one commissioned an independent inspection before contracts were signed.

In the United States and Canada, a pre-purchase home inspection is a standard part of any real estate transaction. Licensed home inspectors operate in a regulated market, follow defined protocols and deliver written reports that buyers use to negotiate price adjustments, attach repair conditions or withdraw from the purchase. The process is routine enough that most North American buyers proceed without much deliberation about how it works.

In Greece, none of that infrastructure exists. There is no regulated home inspection profession operating to a common professional standard. Greek law requires the seller to provide a Technical Diagnostic File before completion. That document covers energy performance certification, electrical compliance and environmental checks. It does not assess the structural condition of the building. It does not compare the physical structure against the approved building permits. It is not a home inspection in any sense that a North American buyer would recognize.

What American and Canadian buyers call a "house inspection" in Greece is, in practice, an independent technical inspection commissioned by the buyer, outside the legal transaction requirements, from an advisor operating exclusively on the buyer's side. Understanding what that inspection should cover, when to commission it and how to evaluate the independence of whoever carries it out is the practical knowledge this guide provides.

Why the US Home Inspection Model Does Not Transfer to Greece

Three structural differences between the US and Greek property markets determine why direct transfer does not work.

The first is permit complexity. In the United States, properties are generally sold with permits in order and building code compliance documented. Violations, if they exist, are typically disclosed or discoverable through the local authority. In Greece, unauthorised constructions (structures built or modified without the relevant permit) are endemic in the residential property stock. A 2011 government amnesty programme produced over 800,000 declarations of unauthorised construction. Under Law 4495/2017, many of these violations have been temporarily suspended but not resolved. They transfer to the new owner on purchase. A US-style visual inspection, conducted without reviewing the permit drawings held at the urban planning authority, will not identify them.

The second is building era and seismic context. Most of the Greek residential stock that attracts foreign buyers, including villas on the islands, apartments in central Athens and rural stone buildings in the Peloponnese, was constructed before modern seismic design standards became mandatory practice in Greece. Athens sits in seismic zone 2 and 3 under the national hazard classification. Crete is classified in zone 4, the most demanding. Structural assessment of pre-1985 buildings in this seismic context requires technical reading of the construction method against the site's hazard exposure, not just a visual inspection of surface conditions.

The third is the absence of a uniform disclosure standard. Greek sellers are not required to disclose structural defects, unauthorised modifications or deferred maintenance. The legal framework places the burden of technical investigation on the buyer. An estate agent in Greece will provide the information they are required by law to provide. Structural soundness, permit compliance and ten-year capital expenditure are not among those requirements.

What a House Inspection in Greece Should Cover

A professional independent inspection of a Greek residential property covers four areas that the seller-mandated documentation does not address.

Structural condition. The building frame, foundations, roof structure and load-bearing walls assessed against the building era, construction method and seismic exposure at the specific location. Pre-1985 properties require examination for seismic retrofit status. Stone buildings in the Peloponnese and Epirus require different structural assessment than reinforced concrete apartment construction in central Athens. The inspection must be calibrated to the specific asset.

Permit compliance. An independent technical advisor compares the physical structure against the approved building permit drawings held at the relevant urban planning authority. This comparison, structure against permit, is the mechanism by which unauthorised constructions are identified. Rooftop additions, enclosed verandas, basement conversions and extensions built without permits are the most common violations found in inspections across Athens, Crete, the Ionian Islands and the Peloponnese. Each represents a liability that transfers to the buyer on completion. The guide to illegal constructions in Greece covers what these violations mean in practice and what regularisation costs under Law 5261/2025 look like.

Building systems. Electrical installation, plumbing, heating and cooling systems. Pre-1975 apartment buildings in central Athens frequently carry original or informally modified electrical installations across multiple ownership transfers. Electrical rewiring of a 90-square-metre Athens apartment typically costs between 8,000 and 15,000 euros depending on scope and access. Hot water systems, plumbing age and heating infrastructure all carry material replacement cost that should be quantified before price negotiations are concluded.

Deferred maintenance and ten-year capital expenditure. Waterproofing membranes on flat-roofed Greek residential buildings have a typical service life of 15 to 25 years. Roof replacement in Athens ranges from 60 to 150 euros per square metre. Island properties carry specific exposure to salt air corrosion on metalwork, window frames and external fixtures. The property condition assessment covers the ten-year capital expenditure framework in detail, including cost ranges by system and building era.

BEFORE YOU COMMIT TO A PROPERTY IN GREECE

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

We perform preliminary remote acquisition reviews for American and Canadian buyers evaluating properties across Greece and the Mediterranean.

This early-stage review identifies: structural risk indicators based on building era and seismic zone, permit documentation gaps, estimated capital expenditure by category, utility compliance issues, and whether a full on-site inspection is justified before any commitment is made.

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

House Inspection vs Property Survey vs Technical Due Diligence: Which One Do You Need?

Three terms are in common use among foreign buyers in Greece, and they do not map to three separate services. They map to different terminological habits by nationality and to different levels of scope.

House inspection and home inspection are the terms most used by American and Canadian buyers. They describe a pre-purchase technical assessment of physical condition. The scope typically covers structural condition, building systems and visible defects. In Greece, a proper house inspection must also include the permit compliance review that US home inspection practice does not address.

Property survey is the term most commonly used by British buyers. In content, it covers the same territory as an independent property inspection. The property survey guide for foreign buyers covers the UK-specific context and what British buyers should expect instead of a RICS-standard survey.

Technical due diligence is a more extensive mandate appropriate for acquisitions above 500,000 euros, institutional purchases, hospitality assets and multi-unit developments. It includes all physical assessment elements plus MEP system review, a formal capital expenditure projection, detailed permit mapping, contractor execution risk assessment and a report structure suitable for financing discussions or investment committee review.

For most private buyers purchasing a villa or apartment in Greece at values between 150,000 and 800,000 euros, an independent property inspection covering structural condition, permit compliance, building systems and deferred capital expenditure is the appropriate instrument.

What Does a House Inspection Cost in Greece?

An independent technical inspection of a standard residential property in Greece starts from 5,000 euros. The fee covers travel to site, a full inspection day, permit document retrieval and review, and a written English report. Total cost varies with property size, location and the complexity of the permit documentation.

Inspections priced below 2,000 euros should be examined carefully. A fee at that level cannot accommodate a complete permit compliance review, a structural assessment calibrated to the building era and seismic context, and a professional written report. What it typically provides is a visual walk-through and brief verbal summary, useful for identifying surface defects but not for the permit violations and structural issues that represent the highest-cost risks in the Greek market.

Island properties carry additional logistics costs. Mykonos, Rhodes, Crete, Corfu and Kefalonia each involve travel costs, ferry or flight scheduling and, in some cases, local permit document retrieval from island-specific planning authorities. The cost of the inspection on Santorini or Mykonos will be higher than the equivalent assessment in central Athens. That additional cost is not discretionary in markets where agent-recommended inspectors operate with undisclosed referral relationships to the selling agent.

How to Find an Independent Home Inspector in Greece

Three checks before engaging anyone to inspect a property in Greece.

First, confirm in writing that the inspector has no referral arrangement with the selling agent. The most common inspection arrangement in the Greek residential market involves an inspector recommended by the agent introducing the buyer to the property. This arrangement contains a structural conflict of interest. An inspector with a referral relationship has a commercial reason to complete the transaction, not to identify problems that would complicate it.

Second, require that the inspector confirm their familiarity with the permit compliance framework under Greek Law 4495/2017. The permit compliance review is the component of a Greek property inspection that differs most significantly from US home inspection practice. An inspector who cannot read Greek planning documents and compare them against the physical structure cannot identify unauthorised constructions. That is the gap most likely to result in a six-figure cost appearing after purchase.

Third, require a written report in English delivered before the preliminary contract is signed. The full guide to choosing a property inspector in Athens covers the specific questions to ask before commissioning anyone for an acquisition in Attica, including what to put in writing before the inspection begins.

When to Commission a House Inspection in Greece

Before the preliminary contract is signed. Not after.

This sequence matters because of what the preliminary contract establishes in the Greek legal framework. Once signed, the preliminary contract locks both parties into a defined set of obligations. A buyer who withdraws after the preliminary is typically liable to forfeit the deposit, usually 10% of the agreed purchase price. A seller who withdraws is liable to return double the deposit.

Structural findings, permit violations and deferred capital expenditure identified before the preliminary can be used to renegotiate the purchase price, attach repair conditions to the agreement or withdraw without financial penalty. The same findings identified after the preliminary contract have none of those practical applications. The inspection cost is identical in both cases. The leverage to act on what it finds is not.

Buyers in Greece are sometimes advised by estate agents to commission inspections after the preliminary contract, framed as the standard sequence of events. That framing reflects the agent's interest in completing the transaction, not the buyer's interest in protecting their position. The guide to buying property in Greece as an American covers where the technical inspection step fits within the full transaction timeline, including the FATCA and FBAR obligations that apply to US buyers.

Frequently Asked Questions

Q: Is a home inspection required when buying property in Greece?
A: No. Greek law requires the seller to provide a Technical Diagnostic File covering energy performance, electrical compliance and environmental checks. An independent structural and permit inspection is not legally required. It is the only mechanism available to the buyer for identifying structural defects, unauthorised constructions and deferred maintenance costs before purchase. The seller is not required to disclose these. Without an independent inspection, the buyer assumes them.

Q: What does a house inspection in Greece cover?
A: An independent house inspection in Greece covers structural condition, permit compliance (comparing the physical structure against approved building permit drawings held at the urban planning authority), building systems including electrical, plumbing and HVAC, roof and waterproofing condition, and a ten-year capital expenditure projection. The permit compliance review is the element that differs most from US home inspection practice and the one that carries the highest financial risk if omitted.

Q: How much does a home inspection cost in Greece?
A: An independent technical inspection of a residential property in Greece starts from 5,000 euros. This covers travel to site, a full inspection day, permit document review and a written English report. Island locations carry additional logistics costs. Inspections priced below 2,000 euros generally do not include a complete permit compliance review and should be examined carefully before commissioning.

Q: When should I get a house inspection in Greece?
A: Before the preliminary contract is signed. Findings at this stage can be used to renegotiate the purchase price, attach repair conditions or withdraw without financial penalty. A house inspection commissioned after the preliminary contract loses all practical leverage to act on what it finds. The inspection cost is the same either way.

Q: What is the difference between a house inspection and technical due diligence in Greece?
A: A house inspection, also called a property inspection, covers physical condition, permit compliance, building systems and capital expenditure exposure. It is appropriate for most private residential acquisitions. Technical due diligence is a more extensive mandate for acquisitions above approximately 500,000 euros, hospitality assets, multi-unit developments and institutional purchases. It extends the inspection scope with formal CapEx modelling, MEP systems review and a report structure suitable for financing or investment committee review.
