Security clearance and military zones: what a foreign buyer needs to know

In short
Foreigners cannot own property inside restricted military zones and security zones, and the law also sets a cap on foreign ownership in each administrative district and a maximum per person. In provinces where these zones have been officially mapped, a property’s status is known immediately; elsewhere, the tapu (land registry) directorate makes an enquiry to the relevant military authority, which can add time to the transaction. Find out the property’s status early, and do not pay large sums before you are sure.

It may surprise you that buying an ordinary flat involves a question about “military zones”. The reason is that Turkish law protects certain areas from foreign ownership, and the tapu (land registry) directorate is responsible for checking this before every sale to a foreigner.
What does the law say?
Article 35 of the Land Registry Law governs foreign ownership, including:
- Restricted military zones and security zones: foreigners cannot own property in them.
- Strategic zones: ownership may be allowed with special approval.
- District cap: the total owned by foreigners may not exceed 10% of the private land area in the administrative district.
- Per-person cap: a single foreigner may not own more than 30 hectares across all of Turkey.
The general details are in the guide to foreign ownership.
How is it checked?
- In mapped provinces: the official mapping of military and security zones has been completed in dozens of provinces, so the property’s status is known immediately and no separate enquiry is needed.
- Elsewhere: the tapu directorate sends an enquiry to the relevant military authority and waits for the reply before completing the sale.
How much time does this add?
It varies by province and the property’s location. For flats in cities it is usually not an obstacle, but it can take longer for land and for sites near military or border installations.
How to plan
- Ask early: before paying a deposit, ask about the property’s status and the province.
- Tie the deposit to the outcome: state in the deposit contract that the money will be refunded if the sale is refused for a legal reason relating to foreigners.
- Do not book the tapu appointment until the status is clear in provinces that require an enquiry.
- Take care with land: the risks are higher and the enquiry takes longer. See the Arnavutköy land guide.
What about Trabzon and Istanbul?
Most flats in residential neighbourhoods face no problem, but the status is checked for each property individually, especially land and properties near military installations, ports or airports.
Summary
The military enquiry is not an obstacle in most deals, but in some locations it can cause an unexpected delay or a refusal. Find out the property’s status before you pay, and keep your appointment flexible where an enquiry is required.

View, orientation and sun: why a sea-view flat in Trabzon may get less sunlight
In Trabzon the sea lies to the north, so a flat that looks straight onto it faces north and gets less sun, and north-facing walls are more prone to damp. The best options are often a corner flat or one with two façades: a sea view to the north and sun from the south or west. A view raises value and demand, but check that it will not be blocked by new construction, and check the light and warmth in winter.

Video viewings: how to see a flat as if you were there, from your own country
A live video viewing saves many trips if you lead it yourself: ask for one continuous, uncut tour; start from the street and the entrance, then every room, window and balcony; turn on the taps and open the cupboards; ask to see the view in every direction, the north-facing walls and the corners for damp, and the way to the nearest amenities. Record the tour and ask for the documents afterwards. For a property you will spend a large sum on, treat the video as a filter before a visit or a second tour at a different time.

Urban transformation in Istanbul: what it means for buyers and owners of older flats
Kentsel dönüşüm (urban transformation) in Turkey is governed by Law 6306 on rebuilding buildings at earthquake risk. A licensed body’s report classifies a building as risky, and this is recorded at the tapu (land registry). Since November 2023, rebuilding decisions need an absolute majority of the owners’ shares instead of two thirds, and a February 2026 regulation changed the procedures, such as selling objecting owners’ shares. Owners may get rent assistance under conditions. Buying in an old building means buying a share of the land and a future project: read the legal position carefully.
