The Occupancy Certificate (İskan) in Turkey: Why You Shouldn't Buy a New Flat Without It

In short

The occupancy certificate (Yapı Kullanma İzin Belgesi) is issued by the municipality once construction is complete and it has confirmed the building matches its permit. Without it, utility accounts stay temporary at the construction tariff, the title deed cannot convert from kat irtifakı to kat mülkiyeti, and selling and borrowing become harder. When buying a ready flat, ask for a copy; when buying off-plan, write a deadline for its issue into the contract.

Imagine buying a new flat with a stunning view, then discovering your electricity bill is higher than your neighbours', the bank refuses to value it for a loan, and a potential buyer walked away after asking about the “iskan”. That is what happens when a flat is bought without an occupancy certificate. In this guide we explain what it is, why it matters to you, and how to protect yourself.

What is the occupancy certificate?

Its official name is “Yapı Kullanma İzin Belgesi”, meaning building use permit. The municipality issues it once construction is complete, after confirming the building was built according to the permit and approved plans, and that requirements such as parking, emergency exits and earthquake insurance have been met. In short: it certifies that the building is legally fit for habitation.

Why does it matter to you as a buyer?

1. Water, electricity and gas

Without the iskan, utility accounts usually run on the temporary “construction” tariff, which is sometimes higher, and you may later be asked to re-subscribe. With the iskan, the accounts are transferred permanently into your name.

2. Converting the tapu to kat mülkiyeti

The title deed in a building without an iskan remains “kat irtifakı” (construction servitude). The issue of the iskan is what allows it to be converted to “kat mülkiyeti” (condominium ownership), the full title deed that is easier to sell. We explain the difference in the guide to kat irtifakı and kat mülkiyeti.

3. Resale and loans

Turkish buyers and banks ask about the iskan before anything else. A flat without one is harder to sell, often at a lower price, and most banks will not accept it as collateral for a loan.

4. Violations

An iskan delayed for years can be a sign of a building violation: an extra floor, a change to the plans, or a problem with the land. These can mean fines or alterations at the owners' expense.

Buying off-plan: how to protect yourself

Projects under construction naturally don't have an iskan yet. Protect yourself with three things:

  1. The building permit: make sure the project is permitted, and that the number of floors and units in the permit matches what is being marketed.
  2. A deadline in the contract: write an expected date for the iskan into the sales contract, and what happens if it is late.
  3. The developer's track record: did their previous projects obtain an iskan within a reasonable time? See the guide to choosing a reliable developer and the off-plan buying guide.

Buying in an older building

Among older buildings you will sometimes find blocks that have had no iskan for decades. This does not necessarily mean they are dangerous, but it does mean you need a deeper check of their legal and structural status, and that resale later will be to a narrower pool of buyers.

How to check, step by step

  1. Ask the seller or developer for a copy of the occupancy certificate.
  2. Look at the title deed type: kat mülkiyeti usually indicates the iskan has been issued.
  3. Ask the municipality about the building file using the ada (block) and parsel (plot) numbers.
  4. Compare the number of floors on the certificate with what you see on the ground.

These steps are part of the 12 checks before buying that we apply to every property.

Summary

The occupancy certificate is not a formality. It is what makes your flat a property with full rights: permanent utility accounts, a full title deed, and the ability to sell and finance. Ask for it on ready properties, and make it a dated condition on off-plan ones.

We state the iskan status of every property we list. You can browse available flats or contact us to ask about a specific property.

    A trustworthy real estate company in Turkey holds a brokerage licence and a chamber of commerce registration, has a real office you can visit, publishes the real price and puts its commission in writing before it starts, hands you the title deed in your name at the land registry, and never asks you to pay the price of the property into its own account. Ask any agency these ten questions before you sign.

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

    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.

  • Mortgages, seizures and annotations on the tapu record: how to read a property’s record before buying

    The tapu (title deed) record, Tapu Kaydı, shows the owner and everything that encumbers the property: a bank mortgage (İpotek), a seizure in favour of a creditor (Haciz), a court injunction (Tedbir), annotations such as a lease, a promise of sale or family home status, declarations such as a risky building decision, and easement and usufruct rights. A bank mortgage can be released on the day of sale by arrangement with the bank, while a seizure or injunction must be lifted before the transfer. Ask for a fresh record before any payment and again just before the appointment.
