and Why Your Lawyer Can't Do It
You've found the apartment in Athens. The views are stunning, the agent is responsive, and the price falls within the Golden Visa threshold. Your lawyer has run the title check and confirms clean ownership. Everything looks good.
But here's the question nobody is asking: what about the building itself?
In Greece, the property transaction process has a well-known blind spot. Lawyers handle the legal side ownership history, liens, encumbrances, cadastral records. What they don't do is walk into the building, compare the physical structure against the approved plans, and tell you whether the enclosed balcony was ever permitted. That's not a criticism of lawyers; it's simply outside their scope. It requires a registered civil engineer.
Most foreign investors in Greece hire a lawyer and assume the due diligence is complete. In markets like the UK, the Netherlands, or the US, a building survey or home inspection is a standard part of the buying process. In Greece, it isn't. There is no standardized survey framework equivalent to the RICS system, and no legal requirement for the buyer to commission a technical inspection before signing.
This means you can complete a legally valid property purchase in Greece without anyone ever checking whether the building is structurally sound, whether the actual floor plan matches the approved drawings, or whether the basement that's been converted into a bedroom was ever permitted.
For a Golden Visa investment of €250,000 to €800,000, that's a significant blind spot.
A property audit is a comprehensive technical assessment performed by a qualified, independent engineer — not someone recommended by the seller or the agent. The word "independent" is the critical distinction: the engineer works for you, reports to you, and has no financial interest in the transaction going through.
The audit typically covers three areas:
For a Golden Visa investment of €250,000 to €800,000, that's a significant blind spot.
The engineer inspects the foundation, load-bearing walls, slabs, columns, and reinforcement condition. In a country that sits on one of Europe's most active seismic zones, this is not optional. Buildings constructed before 1985 were built under older seismic codes, and many have never been evaluated against current standards. The engineer assesses whether the building meets the requirements of the current Greek Seismic Code (EAK 2000) and the Eurocode 8 provisions, or whether it would require retrofitting.
This is where most surprises appear. The engineer compares the physical building against the official approved drawings held at the local planning authority (Πολεοδομία). Common findings include enclosed balconies that were never declared, basement or attic conversions without permits, additional rooms or mezzanines that don't appear on the plans, and changed building use (commercial to residential or vice versa) that was never formally approved. Under Law 4495/2017, unauthorized constructions, known as αυθαίρετα (afthaireta), must be regularized before a property can be legally transferred. The engineer identifies these violations and estimates the regularization cost, which can range from €1,000 to over €40,000 depending on severity.
Beyond structure and permits, the audit evaluates the mechanical, electrical, and plumbing (MEP) systems, the building envelope (walls, roof, windows), moisture and insulation performance, and the property's Energy Performance Certificate (EPC). The engineer provides renovation cost estimates where needed, giving you a realistic picture of what the property will actually cost , not just the asking price.
The answer is straightforward: it's not in their interest. The seller wants to close the deal. The agent earns a commission on the sale. Neither party benefits from a report that might reveal problems.
This is not unique to Greece, it's how real estate works everywhere. But in Greece, the combination of widespread unauthorized construction (some estimates suggest that a significant share of the building stock has some form of permit irregularity), an older building stock with seismic concerns, and the absence of a mandatory inspection framework makes the gap particularly consequential for foreign investors who aren't familiar with the local landscape.
In Greece, a property audit should be performed by a Diploma Civil Engineer (Πολιτικός Μηχανικός) registered with the Technical Chamber of Greece (TEE). This is the professional who has the legal standing to evaluate structural adequacy, verify building permits, and sign off on regularization submissions. An architect can assess design and planning compliance, but structural assessment requires a civil engineer's qualification.
The strongest combination — and one that is relatively rare — is a professional who holds both qualifications: civil engineer and architect. This means a single practitioner can evaluate structural safety, legal compliance, design quality, and renovation feasibility in one integrated report, rather than requiring two separate professionals.
At Greece Property Audit, the deliverable is a comprehensive English-language PDF report structured around a clear "Traffic Light" executive summary — Green (proceed with confidence), Yellow (proceed with conditions), or Red (significant issues identified). The report includes photographic documentation, annotated plan comparisons, defect analysis, cost estimates, and specific recommendations. It's designed to give you the information you need to make your investment decision — or to renegotiate the purchase price.
The process is simple: submit your property details through the audit request form, receive a flat-fee quote within 24 hours, and get your complete report within 72 hours of the site inspection. No hidden costs. No percentage-based commissions. No surprises.
