Closing the connection of a duplex or attic floor and opening a separate entrance is not a “right”; it is often a zoning violation and a risk of demolition/penalty. We discuss this risk and the ways to legalize the situation in urban transformation in detail.
A very common scenario: A duplex or attic floor, over the years, has been effectively converted into a second apartment by closing off the connection from the lower floor and opening a separate entrance. While the owner sees this as a “right,” legally, the opposite risk is involved. This article addresses the risk of demolition and fines for an attic floor divided contrary to the project, and how this situation can be legalized in urban transformation.
Why is the Division Process Contrary to Zoning and the Condominium Law (KMK)?
The Planned Areas Zoning Regulation prohibits the creation of independent sections in attics; only spaces connected to the independent section on the top floor can be built there PAIY art.40/7. The regulation also explicitly states that the volume between the roof covering and the top floor ceiling slab cannot be divided by adding extra floor slabs PAIY art.40/8. Furthermore, under the Condominium Law (KMK), condominium owners are obliged to preserve the architectural state of the main property KMK art.19. Therefore, closing the internal connection of a duplex and opening a separate entrance constitutes a violation of the approved project.
Sanctions Faced
| Basis | Sanction |
|---|---|
| Zoning Law Art. 32 | Upon determination of the violation, issuance of a construction suspension report and restoration to the previous state by giving a deadline; if not remedied, demolition by the administration |
| Zoning Law Art. 42 | Administrative fine due to violation of zoning regulations |
| Law on Condominium Ownership Art. 19 | Other co-owners being able to file a lawsuit for restoration to the previous state (in compliance with the project) |
These sanctions become relevant when the violation is detected by the municipality, and often arise during the urban transformation/licensing process.
What Happens in Urban Transformation? The Expectation of “Automatic Two Flats” is Incorrect
Actual subdivision does not automatically grant the right to two flats in a new project. On the contrary, a violation of the project can become an obstacle during the licensing and occupancy permit process of the new building. In urban transformation, distribution is not based on the actual situation, but on the land share and the number of independent sections in the title deed. Even if two flats are actually being used, if there is only one independent section in the title deed, that single independent section is taken as the basis for the transformation.
How to Acquire Legal Status?
It is not impossible to bring the de facto situation into legal compliance in the new building; however, this does not happen automatically:
Apply to the municipality and integrate it into the project: It should be clarified with the municipality whether these floors can be processed in accordance with the new architectural project; if possible, the project amendment and occupancy permit should be completed.
Consent of all owners: The new project showing this location as two separate independent sections generally requires the consent of all owners and compliance with zoning regulations.
Land share and allocation scheme: If an additional independent section is acquired, the payment of a goodwill/value difference to other owners comes into question. If the building cannot be legalized, the court may consider registration based on the land share instead of a direct independent section deed.
The scope and current validity of mechanisms such as the building registration certificate (zoning amnesty) should be evaluated separately and carefully; this document alone may not create an independent section or land share. Therefore, the current status should be confirmed for each case.
Pre-Conversion Checklist
Compare the approved project with the actual situation. Does the project include a separate entrance/division, or does it constitute a violation?
Inquire with the municipality about the zoning status and any violation records, if any. Is there a risk of a construction stop order or penalty?
Investigate the possibility of legalization. Is a solution possible through project amendment, consent, and occupancy permit?
Contractually secure the share and goodwill. Additional apartment acquisition should be established with a fair balance of cost/goodwill.
Obtain legal and technical support before signing. In cases involving discrepancies, a single wrong step can lead to both penalties and loss of rights.
Frequently Asked Questions
Is it legal to close off the duplex connection and create a separate entrance?
No, as a rule, it is contrary to the project. The Regulation on Zoned Areas prohibits the creation of independent sections in attics (Article 40/7) and states that this volume cannot be divided by an additional floor slab (Article 40/8). Apartment owners are also obliged to preserve the architectural integrity (Condominium Law Article 19).
What penalties will I face for a division contrary to the project?
Pursuant to Article 32 of the Zoning Law, a construction holiday report can be issued and restoration to the original state may be requested; if not rectified, demolition by the administration becomes an agenda item; an administrative fine may be imposed pursuant to Article 42. Additionally, other apartment owners may file a lawsuit for restoration to the original state under Article 19 of the Condominium Law.
I am currently using two apartments; will I automatically get two apartments in urban transformation?
No. Actual division does not automatically grant the right to two apartments in a new project; on the contrary, it can create an obstacle during the licensing/occupancy permit process. The distribution is made not according to the actual situation, but according to the land share in the title deed and the number of independent sections. How can I legalize this situation?
It is necessary to apply to the municipality to clarify whether the floors can be incorporated into the new project, complete the project amendment and occupancy permit if possible, obtain the consent of all owners, and pay the premium/value difference if required. If the building cannot be legalized, the court may evaluate the registration based on the land share.
Does the building registration certificate (zoning amnesty) solve this problem?
The scope and current validity of the building registration certificate should be carefully evaluated; this document alone may not create an independent section or land share. The current status must be confirmed in each file.
