What Is the Coastal Edge Line in Turkey? What You Can Build on Seaside Land
🇹🇷 This article describes regulations and processes specific to Turkey — requirements differ in other countries.
A plot with a view on the Black Sea coast looks appealing, but its distance from the shore directly determines what can legally be built on it. We explain the boundaries set by Turkey's Coastal Law and what they mean in practice.
A plot with a view along the Black Sea coast looks attractive as an investment — but the plot's distance from the shore sets legal limits, defined by law, on what can be built on it. Investing in coastal land without knowing this boundary can lead to serious disappointment.
The difference between the shoreline and the coastal edge line
The shoreline is the actual physical point of contact between the sea and the land at any given moment — it can shift slightly with waves and seasons. The coastal edge line is a more permanent boundary: on low, flat coasts, it marks the landward natural boundary of areas shaped by water movement — beaches, rocky areas, reed beds; on the steep, high coastlines (cliffs) common around Trabzon, it follows the upper edge of the slope or cliff face instead.
What does the Coastal Law say?
In the area between the shoreline and the coastal edge line, only structures intended for public use of the coast — as listed in the Coastal Law, such as piers, harbors, and landing points — are permitted, and even these only where shown on an approved zoning plan. Privately owned structures such as houses and villas cannot be built in this zone.
The coastal strip and the 50-meter setback
The law defines a band of at least 100 meters measured from the coastal edge line as the "coastal strip." Within this strip, structures may come no closer than 50 meters to the coastal edge line; and even within that 50-meter zone, only pedestrian paths and recreational facilities are permitted, and only where a zoning plan exists.
What this means in practice for cliffside (falez) plots
Because the coastal edge line on Trabzon's steep, cliff-lined (falez) sections generally runs along the top of the slope, a plot being "sea-view" is not the same thing as it being "behind the coastal edge line and open to construction." In our Falez Villa project, we established this boundary from the very start and positioned the building mass accordingly.
Our process at MEEZ Mimarlık
When evaluating a plot near the coast, we check the approved coastal edge line map from the relevant municipality or provincial environment directorate to clarify the plot's real building potential — a step that needs to be taken before the decision to buy, not after.
Frequently Asked Questions
Are the coastal edge line and the shoreline the same thing?
No. The shoreline is the sea and land's point of contact at any given moment; the coastal edge line is the landward natural boundary of areas — such as beaches and rocky ground — shaped by water movement, and on narrow, high coastlines like cliffs, it's defined by the upper edge of the slope.
Can housing be built on a plot near the coastal edge line?
Only structures for public coastal use, such as piers or harbors, can be built between the shoreline and the coastal edge line; private structures like housing require a location behind the coastal edge line that complies with the coastal-strip rules.
How do I find out where my plot stands relative to the coastal edge line?
This information appears on the zoning status document or on the relevant municipality's or provincial environment directorate's approved coastal edge line map; it should always be confirmed against that map before buying land.
