Difference Between Kat İrtifakı & Kat Mülkiyeti in Turkey: Occupancy Permit (İskan) Problems for Foreign Buyers

Difference Between Kat İrtifakı & Kat Mülkiyeti in Turkey: Occupancy Permit (İskan) Problems for Foreign Buyers

When purchasing residential or commercial real estate in Turkey, foreign investors and Russian nationals frequently encounter two distinct categories of property title deeds: "Kat İrtifakı" (Construction Servitude) and "Kat Mülkiyeti" (Condominium Ownership). Many international buyers mistakenly assume that possessing a title deed designating an apartment and block number guarantees full legal completion. However, purchasing a property that lacks an official Building Occupancy Permit (İskan / Yapı Kullanma İzin Belgesi) leaves the property relegated to construction servitude, triggering exorbitant construction utility bills, municipal demolition orders, and severe asset devaluation.

Statutory Framework: Condominium Law No. 634 and Zoning Law Art. 30

Under the Turkish Condominium Law (KMK) No. 634 and Zoning Law No. 3194, property ownership regimes and occupancy permits are strictly distinguished:

• Kat İrtifakı (Construction Servitude - KMK Arts. 1/2, 10–14): A provisional servitude right established on land shares corresponding to independent units of a building that is under construction or planned for development. Legally, a property under Kat İrtifakı indicates that construction is either ongoing or has not yet received official municipal certification of completion.
• Kat Mülkiyeti (Full Condominium Ownership - KMK Arts. 1/1, 10–14): The definitive, independent freehold ownership right established over completed individual units (flats, shops, offices) of a building that has been fully inspected and certified by municipal authorities with an official Occupancy Permit (İskan).
• Building Occupancy Permit (İskan / Yapı Kullanma İzni - Zoning Law Art. 30): The official municipal certificate verifying that the building strictly complies with approved architectural blueprints, seismic regulations, fire safety standards, and shelter requirements. Obtaining an İskan is the statutory prerequisite for converting Kat İrtifakı into Kat Mülkiyeti.

Major Risks and Pitfalls of Purchasing Unlicensed (İskansız) Real Estate

In buildings where developers fail or refuse to secure an İskan, foreign property owners encounter severe operational and legal burdens:

1. Inflated Construction-Rate Electricity and Water Bills: In the absence of an İskan, individual residential utility subscriptions cannot be activated. Utilities are supplied through temporary construction-rate meters (şantiye tarifesi), subjecting owners to utility bills 2 to 3 times higher than residential tariffs, alongside frequent service disruptions.
2. Unauthorized Construction and Municipal Demolition Orders (Zoning Law Arts. 32 & 42): If the developer erected unauthorized penthouse floors, enclosed common balconies, converted underground bomb shelters into commercial units, or violated setback boundaries, the municipality refuses the İskan and issues administrative fines and demolition decrees.
3. Developer Social Security (SGK) and Municipal Tax Debts: Municipalities do not grant occupancy permits until the developer presents an official "SGK Clearance Certificate" confirming full payment of worker insurance premiums and municipal fees, leaving unpaid debts on the building residents.
4. Severe Capital Devaluation and Mortgage Ineligibility: Commercial banks strictly reject mortgage applications on properties lacking Kat Mülkiyeti and İskan, making future resale to international and local buyers exceptionally difficult.
5. Complications with Residence Permit and Citizenship Verifications: Turkish immigration authorities enforce enhanced compliance scrutinies on properties lacking occupancy certificates.

How Our Legal Representation Process Works

Gönen Law Firm implements a rigorous 4-step framework to resolve occupancy permit defects and secure condominium titles for foreign clients:

1. Municipal Zoning Archive and Title Registry Due Diligence: Auditing approved municipal blueprints, construction licenses, engineering inspection reports, and developer SGK clearance records to diagnose specific zoning violations and cost parameters.
2. Formal Notary Default Notice to Developer: Serving formal statutory notices on the developer under contract terms and TBK Article 112/470, demanding immediate acquisition of the İskan and conversion to Kat Mülkiyeti.
3. Litigation for Judicial Authorization & Damages in Consumer/Civil Courts: Securing court authorization (nama ifaya izin) allowing apartment owners to complete municipal İskan procedures on the developer's behalf and at their expense, while suing the developer for excess utility bills and property devaluation damages.
4. Administrative Condominium Registration (Kat Mülkiyetine Geçiş): Finalizing administrative filings with the Land Registry Directorate under KMK Articles 12 and 14 to convert provisional servitude titles directly into definitive condominium title deeds (Kat Mülkiyeti).

Critical Risks and Irreversible Mistakes

• Statute of Limitations on Developer Defects: Delaying legal action allows statutory limitation periods under the Turkish Code of Obligations to lapse, extinguishing damage recovery rights.
• Developer Insolvency or Dissolution: If legal actions and asset injunctions are not instituted before the construction entity is liquidated, owners are left with massive collective financial liabilities.
• Strict 60-Day Appeal Windows on Demolition Decrees: Administrative court appeals against municipal demolition decrees and zoning fines must be filed within 60 days of formal notification.
