Greece offers genuine commercial opportunity for international investors in real estate and construction - but the legal framework is layered, the administrative process is demanding, and the risks of proceeding without specialist guidance are material. Greek property law combines the Civil Code (Αστικός Κώδικας), the New Building Regulation (Νέος Οικοδομικός Κανονισμός, Law 4067/2012), and a dense body of planning legislation that has been amended repeatedly over the past decade. Understanding how these instruments interact is the starting point for any serious transaction or development project. This article covers the full cycle: acquisition due diligence, title verification, zoning and building permits, construction contracts, dispute resolution, and the practical risks that international clients most commonly underestimate.
Greek property law operates on a registration-based system. Until the national Cadastre (Κτηματολόγιο) is fully operational across all municipalities, title records in many areas are still held at local Land Registries (Υποθηκοφυλακεία). The distinction matters enormously in practice. The Cadastre provides a definitive, state-guaranteed record of ownership and encumbrances. The older Land Registry system is declaratory rather than constitutive, meaning registration does not by itself create or extinguish rights - it merely records them. A title that appears clean at the Land Registry may still be subject to adverse claims.
Due diligence for a Greek property acquisition must therefore cover at least three distinct layers. First, a title search going back a minimum of twenty years, tracing the chain of ownership through all registered instruments. Second, a check for encumbrances: mortgages (υποθήκες), pre-notations of mortgage (προσημειώσεις υποθήκης), seizures (κατασχέσεις), and pending litigation. Third, a verification of the property's status in the Cadastre, including whether the parcel has been formally registered and whether any disputes over boundaries or ownership have been flagged.
A common mistake made by international buyers is to rely solely on the notary's confirmation that the deed is formally valid. Greek notaries (συμβολαιογράφοι) are responsible for the formal legality of the instrument, not for the substantive accuracy of the title history. Engaging an independent lawyer to conduct the full due diligence search is not optional - it is the primary protection against acquiring a property with hidden encumbrances or disputed boundaries.
Practical scenario one: a foreign investor acquires a coastal plot for hotel development. The notarial deed is executed without a full cadastral search. Post-closing, it emerges that a neighbouring landowner has registered a boundary dispute in the Cadastre. The investor cannot obtain a building permit until the dispute is resolved, which may take two to four years through the administrative courts.
The Forest Registry (Δασολόγιο) adds a further layer of complexity. Greek law under Article 24 of the Constitution and Law 998/1979 on the Protection of Forests provides that forest land cannot be built upon and cannot be converted to other uses except in narrowly defined circumstances. A plot that appears on a topographic survey as agricultural or residential may be reclassified as forest land during the Cadastre process. This reclassification can render an already-purchased plot entirely unbuildable.

Greek land use is governed by a multi-tier system. At the national level, the General Framework for Spatial Planning and Sustainable Development (Γενικό Πλαίσιο Χωροταξικού Σχεδιασμού) sets overarching principles. Regional Spatial Plans (Περιφερειακά Πλαίσια) translate these into regional priorities. At the local level, Local Urban Plans (Τοπικά Πολεοδομικά Σχέδια, introduced by Law 4759/2020) and the older General Urban Plans (Γενικά Πολεοδομικά Σχέδια) define permitted uses, building coefficients, and setback requirements for individual parcels.
The New Building Regulation (Law 4067/2012) is the primary instrument governing what can be built and how. It establishes the building coefficient (συντελεστής δόμησης), which determines the maximum buildable floor area relative to the plot area, and the coverage ratio (ποσοστό κάλυψης), which limits the footprint of the building. These parameters vary significantly by zone and by the specific urban plan applicable to the area.
Outside urban planning zones - a situation that applies to a large proportion of Greek territory, including many coastal and island areas - construction is governed by the rules for out-of-plan areas (εκτός σχεδίου). Under Presidential Decree 6/17.10.1978 and subsequent amendments, out-of-plan construction is permitted only on plots above a minimum area threshold (generally 4,000 square metres for residential use) and subject to strict setback and building coefficient rules. Many investors underestimate how restrictive these rules are, particularly for plots that appear large but fall just below the threshold or are subject to additional restrictions due to proximity to the coastline, archaeological sites, or Natura 2000 protected areas.
The coastal zone presents particular challenges. Law 2971/2001 on Coastlines and Shores defines the public shoreline (αιγιαλός) and the adjacent beach zone (παραλία), both of which are state property and cannot be privately owned or built upon. The exact boundary of the public shoreline is determined by a formal delimitation process conducted by the relevant authority, and in many areas this process has not been completed. Purchasing a plot that appears to extend to the sea without first obtaining a formal shoreline delimitation opinion is a significant risk.
Practical scenario two: a developer acquires a 3,500 square metre plot in an out-of-plan area on a Greek island, intending to build a boutique hotel. After acquisition, the developer discovers that the plot falls below the 4,000 square metre threshold for out-of-plan construction and that a portion of the plot is within the beach zone. The project cannot proceed without either acquiring additional adjacent land or obtaining a special exemption, which requires a separate administrative procedure with uncertain outcome.
The zoning framework is also subject to frequent legislative change. Law 4759/2020 introduced a new generation of local urban plans intended to replace the older system, but implementation is uneven across municipalities. In areas where the new plans have not yet been adopted, the older plans remain in force, sometimes alongside transitional provisions that create genuine ambiguity about permitted uses. Checking the current applicable plan - and its status in the approval process - is an essential step before any acquisition or development decision.
Obtaining a building permit (οικοδομική άδεια) in Greece is a multi-stage administrative process governed primarily by Law 4067/2012 and the implementing regulations issued under it. The process involves the submission of a complete set of architectural, structural, mechanical, and electrical drawings, together with supporting documents, to the competent Urban Planning Authority (Υπηρεσία Δόμησης, ΥΔΟΜ) of the relevant municipality.
Since the introduction of the electronic permit system (e-Άδειες), applications are submitted through a centralised online platform. This has reduced some of the procedural delays associated with the older paper-based system, but it has also introduced new technical requirements for the format and content of submitted documents. A common mistake is to submit drawings that do not comply with the technical specifications of the platform, which results in rejection and requires resubmission from the beginning.
The permit process involves several distinct approvals depending on the nature and location of the project. For properties near archaeological sites, the Central Archaeological Council (Κεντρικό Αρχαιολογικό Συμβούλιο) or the relevant Ephorate of Antiquities (Εφορεία Αρχαιοτήτων) must approve the project. For coastal developments, the approval of the Ministry of Environment and Energy may be required. For large-scale projects, an Environmental Impact Assessment (Μελέτη Περιβαλλοντικών Επιπτώσεων) is mandatory under Law 4014/2011.
Procedural timelines vary. A straightforward residential permit in an urban area may be issued within sixty to ninety days of a complete application. Complex commercial or mixed-use projects requiring multiple agency approvals can take twelve to twenty-four months or longer. Delays are common and are often attributable to incomplete documentation, requests for supplementary information from the reviewing authority, or the need to obtain approvals from multiple agencies in sequence.
The cost of obtaining a building permit includes state fees calculated as a percentage of the estimated construction cost, as well as the professional fees of the supervising engineer (επιβλέπων μηχανικός) who is legally responsible for overseeing compliance with the approved plans. Professional fees for complex projects typically start from the low thousands of euros and scale with project size and complexity. State fees are calculated according to a formula set by ministerial decision and vary by project type and location.
A non-obvious risk is the distinction between a building permit and a certificate of completion (βεβαίωση περαίωσης εργασιών). The permit authorises construction to begin; the certificate confirms that construction has been completed in accordance with the approved plans. Without the certificate, the building cannot be connected to utilities, cannot be registered in the Cadastre as a completed structure, and cannot be legally sold or leased. Many construction projects in Greece have been completed without obtaining the certificate, creating a category of legally irregular buildings (αυθαίρετα) that require regularisation under successive amnesty laws.
Greece has a substantial stock of buildings that were constructed without permits or in deviation from approved plans. Successive legislative amnesties - most recently Law 4495/2017 and its amendments - have provided mechanisms for regularising these structures by paying a fine and obtaining a certificate of regularisation (βεβαίωση εξόφλησης). The regularisation does not grant full legal status equivalent to a properly permitted building; it suspends the demolition order and allows the property to be transacted, but the underlying irregularity remains on record.
For international buyers, the practical implication is significant. Acquiring a property with unresolved unauthorised construction exposes the buyer to the risk that the regularisation certificate lapses (regularisations under Law 4495/2017 are subject to periodic renewal requirements), that the fine has not been fully paid, or that the irregularity is more extensive than disclosed. A thorough pre-acquisition review must include a check of the building's permit history and any regularisation filings.
Practical scenario three: a foreign company acquires a commercial building in Athens for use as office space. The vendor represents that the building is fully regularised. Post-closing, the buyer discovers that the regularisation covers only part of the unauthorised construction and that a significant portion of the usable floor area has no legal basis. The building cannot be used for the intended purpose without further regularisation, which requires payment of additional fines and may not be possible if the relevant amnesty window has closed.
Law 4495/2017 also introduced stricter rules for the transfer of properties with unauthorised construction. A notary is required to attach a declaration by a licensed engineer confirming the property's status before executing a deed of transfer. However, the engineer's declaration covers only what is visible and documented at the time of inspection - it does not guarantee that all irregularities have been identified. Independent verification remains essential.
The regularisation framework interacts with the Cadastre process in a way that creates additional risk. When a property is registered in the Cadastre, the registration reflects the legal status of the building as documented. An irregularity that was not regularised before the Cadastre registration may be recorded as a legal defect that affects the property's marketability and mortgageability.

Construction in Greece is governed by the general provisions of the Civil Code on contracts for work (σύμβαση έργου, Articles 681-702 of the Civil Code) and by specific provisions applicable to public works contracts under Law 4412/2016. For private construction, the parties have significant contractual freedom, but certain default rules apply unless expressly excluded.
Under Article 688 of the Civil Code, the contractor is liable for defects in the work for a period of five years from delivery for immovable property. This warranty period is mandatory and cannot be reduced by contract. The employer must notify the contractor of any defect within a reasonable time after discovery, and the contractor has the right to remedy the defect before the employer can claim damages or rescission.
The role of the supervising engineer (επιβλέπων μηχανικός) is a distinctive feature of Greek construction law. The engineer is appointed by the owner and is legally responsible for supervising the execution of the works in accordance with the approved plans and the building permit. The engineer signs the permit application and the completion certificate. If the works deviate from the approved plans, the engineer bears professional and potentially criminal liability. For international clients, this creates a practical question about the allocation of responsibility between the contractor, the engineer, and the owner when defects or deviations arise.
Construction contracts in Greece frequently lack the level of detail that international clients expect. A common mistake is to proceed with a brief letter of agreement or a standard-form contract that does not address payment milestones, delay penalties, variation procedures, or dispute resolution mechanisms. When disputes arise - as they frequently do in construction projects - the absence of clear contractual provisions forces the parties into litigation under the general provisions of the Civil Code, which is slower and less predictable than a well-drafted arbitration clause.
The Greek courts have jurisdiction over construction disputes by default. The Court of First Instance (Πρωτοδικείο) has jurisdiction for claims above a threshold value, and the Magistrates' Court (Ειρηνοδικείο) for smaller claims. Litigation timelines in Greek courts are long - first-instance proceedings in commercial disputes typically take two to four years, and appeals extend the timeline further. For international parties, including an arbitration clause in the construction contract - referring disputes to an established arbitration institution - is a practical alternative that provides a more predictable timeline and enforceability under the New York Convention.

Real estate and construction disputes in Greece arise in several distinct contexts: title disputes, boundary disputes, permit challenges, construction defect claims, lease disputes, and expropriation compensation proceedings. Each has its own procedural framework and competent court or authority.
Title and boundary disputes are heard by the civil courts. Where the dispute involves a Cadastre registration, the party challenging the registration must file a claim before the competent civil court within the statutory period. Under Law 2664/1998 on the National Cadastre, initial registrations in the Cadastre are subject to a challenge period, after which the registration becomes final and binding. Missing this challenge period - which varies depending on the stage of the Cadastre process in the relevant area - can result in the permanent loss of a claim to ownership.
Administrative challenges to building permits and planning decisions are heard by the Administrative Courts (Διοικητικά Δικαστήρια). A third party who believes that a permit has been issued unlawfully - for example, because the approved building exceeds the permitted building coefficient - can file an annulment action before the Administrative Court of First Instance. The Council of State (Συμβούλιο της Επικρατείας) hears appeals in planning cases of broader significance. Administrative litigation timelines are similarly long, and interim measures (αναστολή εκτέλεσης) suspending the effect of an administrative act are available but require a separate application and are not routinely granted.
Expropriation (απαλλοτρίωση) of private property for public purposes is governed by Law 2882/2001. The owner is entitled to compensation at market value, determined by a court if the parties cannot agree. A non-obvious risk for foreign investors is that expropriation can be declared over property that is subject to a development project, and the compensation process can take several years, during which the owner cannot develop or sell the property freely.
For disputes involving foreign parties or cross-border transactions, international arbitration is increasingly used. Greece is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, and foreign arbitral awards are enforceable in Greece through the standard exequatur procedure before the Court of First Instance. The procedural requirements for exequatur are set out in Articles 903-905 of the Code of Civil Procedure (Κώδικας Πολιτικής Δικονομίας), and the process typically takes three to six months if uncontested.
The risk of inaction in real estate disputes is particularly acute. Limitation periods under the Civil Code for property-related claims are generally twenty years, but specific claims - such as challenges to Cadastre registrations or administrative permit decisions - have much shorter deadlines, sometimes as short as sixty days from notification. Failing to act within these windows can permanently extinguish a valid claim.
Loss caused by an incorrect litigation strategy in Greek real estate disputes can be substantial. Pursuing a civil claim when the correct route is an administrative challenge, or vice versa, results not only in wasted legal costs but in the expiry of the correct deadline while the wrong proceedings are pending. Early specialist advice on the correct procedural route is not a luxury - it is the primary risk management tool.
What are the main legal risks for a foreign company acquiring commercial property in Greece?
The primary risks fall into three categories. First, title defects arising from the dual Land Registry and Cadastre system, including unresolved boundary disputes and encumbrances not visible from a superficial search. Second, planning and zoning irregularities, including unauthorised construction that has not been properly regularised and restrictions arising from forest, coastal, or archaeological designations. Third, permit and completion certificate issues that prevent the property from being legally used or transferred. Each of these risks requires a specific due diligence workstream conducted by a lawyer with knowledge of the local administrative records, not just the notarial documents.
How long does it take to obtain a building permit in Greece, and what are the main cost drivers?
For a straightforward residential project in an urban area with a complete application, the permit can be issued within sixty to ninety days. Commercial or mixed-use projects requiring environmental assessment, archaeological clearance, or coastal authority approval typically take twelve to twenty-four months. The main cost drivers are the professional fees of the architect and engineers preparing the application, the state fees calculated on the estimated construction cost, and the cost of any specialist studies required. For large projects, professional fees alone can start from the low tens of thousands of euros. Delays caused by incomplete documentation or requests for supplementary information are the most common source of cost overrun in the permit phase.
When is arbitration preferable to Greek court litigation for construction disputes?
Arbitration is preferable when the parties are from different jurisdictions and need an enforceable award across borders, when the dispute involves technical complexity that benefits from a specialist arbitrator, or when the parties require a faster and more confidential process than Greek court litigation provides. Greek court proceedings in commercial disputes at first instance typically take two to four years, and appeals extend this further. An arbitration clause in the construction contract, referring disputes to an established institution with a defined set of rules, provides a more predictable timeline - typically twelve to eighteen months for a full hearing - and an award enforceable under the New York Convention in over 170 countries. The main trade-off is cost: arbitration fees, particularly for institutional arbitration, are higher than Greek court filing fees, making arbitration more economically viable for disputes above a certain value threshold.
Real estate and construction in Greece present genuine opportunities for international investors and developers, but the legal framework demands careful navigation. Title verification, zoning analysis, permit management, and contract structuring each require specialist attention. The cost of errors - whether a missed Cadastre deadline, an undetected forest designation, or a poorly drafted construction contract - consistently exceeds the cost of proper legal preparation. A structured approach, beginning with thorough due diligence and continuing through each stage of the transaction or development cycle, is the most reliable way to protect the investment.
