A sea-view villa in Greece is priced on its distance to the water. The same distance can decide whether part of it may legally exist. The strip of land along the Greek coast is public by law, private building there is not permitted, and work that stands inside it generally cannot be regularized for a fine the way an enclosed balcony or an unpermitted pool house further inland often can. For a foreign buyer, the coastal line is therefore not a planning footnote. It belongs in the technical due diligence before the price is agreed.

This guide explains the two coastal zones, how the line is fixed and what to request before signing. The legal position of a specific plot is for your Greek lawyer and a licensed surveying engineer to confirm.

What Are Shoreline and Coastal Zone Building Restrictions in Greece?

Greek law separates two coastal zones. The aigialos, usually translated as foreshore, is the land washed by the sea at its largest but usual wave run-up: the reach of ordinary winter storms, not exceptional ones. The paralia, or beach zone, is a further strip of land behind the foreshore, up to 50 meters wide measured from the foreshore line, kept for access between land and sea and for protection of the coast. Where the coastline has moved seaward, a third zone may be recorded, the old foreshore (palaios aigialos).

The foreshore and the beach zone are common-use land belonging to the Greek State. The core statute is Law 2971/2001, substantially revised by Law 5092/2024, which reorganized beach concessions, delineation and enforcement. Treat these law numbers as reference points rather than a summary of current law, and confirm the position with your legal advisor before relying on them.

How the Aigialos and Paralia Lines Are Defined and Approved

The foreshore line is not drawn by the seller’s engineer or read off a listing. It is set by a regional committee that assesses geomorphology, wave exposure, vegetation and slope on site, and its decision is published in the Government Gazette (FEK). Under the 2024 framework, approved lines are recorded on orthophoto bases at the Hellenic Cadastre, and there is a window for objections before a line becomes final.

The practical problem is that many stretches of coast have no approved line, only an old one, or a line approved after the house was built. The foreshore exists in law as a natural feature whether or not anyone has mapped it, so a missing line is not a clean result. It means the plot’s position against the public zone is unconfirmed, and a later delineation can place a terrace, a pool or the corner of a building on the public side.

Building Near the Sea in Greece: What Is and Is Not Allowed

Private construction is not permitted on the foreshore or in the beach zone. Works on the foreshore itself, such as a jetty, a slipway or a sea wall, need a separate state approval for the use of the foreshore. A building permit for the house does not cover them, and a jetty sold with a villa without that paperwork is a liability passing from seller to buyer.

Behind the public zones, the required distance depends on where the plot sits: inside an approved town plan, within a coastal settlement, or outside any plan. In coastal settlements, the planning code places a building at least 15 meters from the approved foreshore line and in every case behind the beach zone line, unless a presidential decree fixes a different building line along an established waterfront. Outside plans, tourist buildings, heights and fencing near the shore carry their own rules, islands often add local decrees, and fences or walls that block public access to the sea are a recurring enforcement target. None of these figures should be applied to a plot without a licensed engineer confirming which rules govern it.

Foreshore and Beach Zone Structures That Cannot Be Regularized

Most unpermitted building work in Greece can be brought into the regularization framework for a fine. That framework, introduced by Law 4495/2017 and now carried into the 2026 Spatial Planning and Urban Planning Code (Law 5306/2026), is covered in our article on the illegal construction regularization deadline. Construction on the foreshore and the old foreshore is excluded, and so is construction in the beach zone, subject to narrow exceptions, for example where rights predate the delineation of the old foreshore. The same provisions restrict the transfer of property carrying excluded unauthorized work. Whether an exception applies is a legal question for your lawyer, not something to assume from the age of the building.

The recurring patterns: a pool deck or terrace extended toward the water beyond the line, a pergola or sun deck on what turns out to be beach zone, retaining walls and stairs cut down to the sand, a mooring platform with no approval, a gate closing a path to the shore. A house built under a valid permit decades ago whose corner falls inside a line approved later. None of them shows up in a listing.

BEFORE YOU COMMIT TO A PROPERTY ON THE GREEK COAST

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

We perform remote asset reviews for buyers and investors evaluating seafront and coastal properties in Greece.

This early-stage review identifies: whether a foreshore line has been approved and referenced in the documents, structures facing the sea that are missing from the approved drawings, pools, terraces, steps and jetties that need survey confirmation, gaps between the permit file and the marketed property, and which specialist inputs the plot will need.

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

What to Request Before Buying Coastal Property in Greece

Four sets of evidence close most of the question. First, the approved foreshore and beach zone line for that stretch of coast with its FEK reference, or written confirmation that none has been approved. Second, a recent topographic survey by a licensed Greek surveying engineer that plots the building, pool, terraces and boundaries against that line. Third, the full permit file with approved drawings, so every structure on site can be matched to what was authorized, the process set out in our guide to building permit due diligence in Greece. Fourth, the Hellenic Cadastre record and diagram, compared with the survey, because a plot registered in private ownership does not by itself settle where the public zone begins.

The work divides cleanly. The lawyer handles title, the cadastre entry and the legal effect of any line. The surveying engineer establishes where the line falls on the ground. The independent technical advisor compares what is built with the drawings and the survey, flags every structure on the seaward side, and assesses its condition. Our comparison of legal vs technical due diligence explains how the two workstreams fit together.

Mykonos Coastal Restrictions and the Islands

Islands concentrate the issue: steep coastlines, small plots and a high price for every meter of waterfront. On Mykonos, the Environment Ministry has used satellite imagery and on-site inspections to identify unauthorized construction, and demolition orders have followed, including at beachfront businesses. For a private buyer the question is not whether enforcement happens. It is whether the villa’s terraces, pool and steps sit where the approved line allows. Our Mykonos villa due diligence report shows how shoreline proximity is handled inside a full review, and a Mykonos property inspection covers the site and permit comparison for a single villa.

Effect on Price, Financing and Resale

A structure inside the foreshore or beach zone usually cannot be resolved with a fine, so it cannot be priced like an ordinary regularization. Its value to the buyer is the cost of removing it plus the loss of whatever feature justified the premium, and it can complicate the transfer itself. A lender’s valuer and the next buyer’s lawyer will ask the same questions, and an unresolved line can hold up a mortgage or a resale. Found before the deposit, it becomes leverage: a price adjustment, removal by the seller before completion, or a contract condition. Found after, it belongs to the new owner.

Buying Coastal Property in Greece?

Before contracts are signed, we review: the approved foreshore line and survey against the structures on site, the permit file and approved drawings, pools, terraces, retaining walls and jetties on the seaward side, visible condition of the building and envelope, and the documentation gaps your lawyer needs to close.

For private buyers and investors acquiring seafront property in Greece, we provide independent property inspections and technical due diligence, coordinated with your lawyer and surveying engineer. Every report is in English and delivered directly to the buyer.

Frequently Asked Questions

What is the aigialos in Greek property law?

The aigialos, or foreshore, is the strip of land washed by the sea at its largest but usual wave run-up. Behind it lies the paralia, or beach zone, which can extend up to 50 meters from the foreshore line. Both are common-use land belonging to the Greek State, and private construction in them is not permitted. The core statute is Law 2971/2001 as amended by Law 5092/2024; confirm the position for a specific plot with your legal advisor.

How close to the sea can you build in Greece?

There is no single national distance. The minimum depends on whether the plot is inside a town plan, in a coastal settlement or outside any plan, and on local island decrees. In coastal settlements, for example, the planning code places buildings at least 15 meters from the approved foreshore line and always behind the beach zone line, unless a presidential decree sets a different building line. A licensed Greek engineer should confirm the building line that applies to the specific plot.

Can a pool or terrace built on the foreshore be legalized in Greece?

As a rule, no. Unauthorized construction on the foreshore, the old foreshore and in the beach zone is excluded from the regularization framework that covers most other illegal building work, subject to narrow exceptions. The same provisions restrict the transfer of property carrying such work, and the structure may have to be removed. Whether an exception applies is a question for your Greek lawyer.

How do I check where the foreshore line is on a property in Greece?

Ask whether a foreshore and beach zone line has been approved for that stretch of coast and obtain the Government Gazette (FEK) reference. Then commission a topographic survey by a licensed Greek surveying engineer that plots the building, pool, terraces and boundaries against that line, and compare it with the permit drawings and the Hellenic Cadastre record. If no line has been approved, treat the plot’s position as unconfirmed rather than clear.

Do coastal building restrictions in Mykonos differ from the rest of Greece?

The national foreshore and beach zone rules apply on Mykonos as everywhere else, with island-specific planning rules layered on top. The island has also been a focus of Environment Ministry inspections of unauthorized construction, so seafront terraces, pools and access steps attract scrutiny. Have the plot surveyed against the approved line and the structures compared with the permit drawings before signing. A property inspection starts from 5,000 euros.
