Property Inspection in Athens:
What Foreign Buyers Need to Know Before Signing
Why Athens Presents Specific Risks
Athens is not a uniform market. A neoclassical in Kolonaki, a 1970s polykatoikia in Exarcheia and a new-build in Glyfada carry fundamentally different risk profiles, and require different inspection approaches. What they share: none of them come with a clean technical history unless you commission one.
Athens and Attica combine high transaction volume with significant permit complexity. The city's rapid post-war expansion produced large volumes of construction with inconsistent permit documentation.
Unauthorized enclosures, converted spaces and undocumented square meters are common across all price brackets - from central apartments to suburban villas.
Five building eras and what they mean for your inspection
Athens has five identifiable building eras, each with distinct structural characteristics. Pre-1940 neoclassical and vernacular buildings are typically load-bearing masonry — attractive to buyers, and often carrying decades of incremental modification that never appeared in the permit file.
The 1960s and 1970s polykatoikia — the reinforced concrete apartment blocks that define central Athens — were built under codes that predate Greece's 1985 seismic regulation update. Pre-1985 concrete carries structural assumptions no longer considered adequate for the seismic load Athens sits on. Structural retrofitting on these buildings, when required, starts at €15,000 and can reach €80,000 before scope is defined.
Structural condition of concrete-frame buildings, many constructed between 1960 and 1990 under pre-modern seismic standards. Building permit compliance cross-referenced against physical structure.
Identification of unauthorized constructions, extensions and enclosed spaces. MEP systems including electrical panels, plumbing and heating infrastructure. Remediation cost assessment delivered as part of the written report.
Rooftop additions and permit exposure
One of the most consistent findings in Athens property inspections is unauthorised rooftop additions. Building terraces, machine rooms, storage structures and informal living space were added across the city's apartment stock throughout the 1980s and 1990s. These additions transfer to the buyer with the title — and with the liability.
Under Greek law, unauthorised constructions do not disappear at the point of sale. Regularisation fines of €200–2,000 per square metre become the buyer's obligation. The deadline under Law 5261/2025 closes 31 March 2028 — after that date, there is no resolution pathway for unresolved exposures.
Enclosed balconies and terraces added without permits are among the most frequent findings. Basement conversions, additional mezzanine levels and extended footprints beyond approved plans are also common.
In coastal Attica - Glyfada, Vouliagmeni, Varkiza - corrosion exposure compounds structural risk in older buildings.
Archaeological discovery risk
Athens sits on millennia of inhabited ground. Renovation and basement excavation work can trigger an archaeological stop order from the Central Archaeological Council. This is not a common outcome on every property, but on sites in central Athens and the historic core it is a quantifiable risk. A thorough inspection scope includes a desktop review of archaeological sensitivity data for the specific plot.

What the inspection covers
An independent property inspection in Athens covers structural condition including slab, column and beam inspection where accessible; permit file review cross-checked against the physical structure; MEP systems assessment (electrical, plumbing, heating) and remaining service life; rooftop and common area inspection in apartment blocks; and visual seismic vulnerability indicators on pre-1985 buildings.
The inspection report is written in English and includes a cost summary of identified exposures. Where relevant, a 10-year capital expenditure projection is included as part of the scope.
