The standard due diligence process for buying property in Greece involves a lawyer. The lawyer will search the title at the Cadastral or Land Registry, verify ownership, identify any mortgages or encumbrances, check for outstanding ENFIA tax liabilities, and review the permit history to establish the property's legal status. This is essential work. It will not tell you anything meaningful about the condition of the building.
The distinction matters because the two most common categories of costly discovery after acquisition in Greece are not legal — they are physical: undisclosed structural problems in the building itself, and the gap between what the permit authorized and what was actually built. The first requires a structural assessment; the second requires a technical cross-check of the physical building against the permit drawings. Neither is part of a lawyer's instruction.
What a Structural Assessment Covers
A structural assessment of a Greek residential property by a qualified civil engineer covers the visible and accessible elements of the building's structure: the primary frame (columns and beams in reinforced concrete construction, or load-bearing walls in older masonry), the floor and roof structure, the foundations to the extent they can be inferred from the building's behaviour and any available documentation, and the condition of the building envelope where it has structural implications.
The engineer will look for evidence of differential settlement — uneven subsidence that can indicate foundation problems or variable ground conditions. Cracking is assessed for its cause and significance: thermal and shrinkage cracking is common and generally benign; structural cracking — particularly diagonal cracking in masonry walls, horizontal cracking at beam-column junctions, or cracking patterns consistent with foundation movement — indicates something more serious. Evidence of previous seismic damage, inadequate repair, or structural alterations carried out without design is recorded and evaluated.
On older properties, the assessment also considers the likely design standard under which the building was originally constructed. A reinforced concrete frame building from the 1960s was built under different code requirements — and typically with different construction practices — than a building from 2005. The engineer's evaluation of the existing structure is informed by this context.
Where the assessment identifies concerns that cannot be fully evaluated from a visual inspection — where the structural condition of key elements is uncertain, or where the building shows signs of significant distress — additional investigation may be recommended: opening up of specific elements, materials testing, or geotechnical investigation of the site.
The Permit Check: What Was Authorized Versus What Was Built
Greece has a substantial inventory of properties that were extended, modified, or altered after their original construction — sometimes with permits, sometimes without. The presence of a building permit in the title file does not mean that what was built corresponds to what the permit authorized.
The technical cross-check involves comparing the physical building — its floor plan, floor levels, footprint, and usable area — against the permit drawings. Where discrepancies exist, the nature and scale of the unauthorized construction matters: minor deviations may be regularizable under current amnesty provisions; significant unauthorized additions, basement rooms, or structural alterations without engineering approval create more serious problems.
Foreign buyers of older properties — island houses, rural dwellings, urban apartments in buildings constructed before 1980 — are the buyers most likely to encounter this type of discrepancy. The seller may be unaware that a problem exists; the issue may have been inherited along with the property through several generations. This does not change the legal and financial implications for the buyer who acquires without checking.
When to Commission a Structural Assessment
The appropriate moment for a structural assessment is before exchange of contracts — during the due diligence period, alongside or immediately following the legal title search. The findings should inform the negotiation: where significant remedial works are required, their cost should be reflected in the purchase price. Where structural problems are severe enough to raise questions about the viability of the intended use, the assessment provides the information needed to make that judgement before commitment rather than after.
A structural assessment is not a standard part of Greek property transactions. Unlike in the UK, where a survey is a normal expectation, Greek buyers and sellers do not routinely commission structural reports. Foreign buyers who adopt the same approach — assuming that the absence of a survey is normal practice and therefore acceptable — are taking a risk that their local counterparts often absorb without full awareness.
The cost of a structural assessment by a qualified civil engineer is modest relative to the acquisition price of any property where the condition is uncertain. On older island properties, rural houses, and anything substantially pre-dating the 1985 regularization period, it should be treated as a standard element of due diligence, not an optional extra.
The Professional Who Should Conduct It
A structural assessment in Greece should be conducted by a licensed civil or structural engineer — not an architect, not a surveyor in the generalist sense, and not a contractor offering a pre-purchase inspection as part of a renovation sales pitch. The engineer should carry professional indemnity insurance, should produce a written report, and should be appointed by the buyer rather than recommended by the seller or the seller's agent.
The report should cover the structural condition of the building, any identified deficiencies, an assessment of their cause and likely progression, a preliminary estimate of the cost of remediation where applicable, and a recommendation as to whether further investigation is required before a final view can be reached.
