Renovations made by a unit owner in their apartment often do not concern only themselves. Interference with the load-bearing system (cutting columns/beams), facade changes, removal of common walls, or additions made to common areas; directly affect both the safety of the building and the rights of other owners. Unauthorized renovations in independent sections and common areas are subject to strict rules under Condominium Law No. 634 (KMK). In this article, we discuss the limits of unauthorized renovations and the legal remedies available against them.

Can a Unit Owner Make Any Desired Changes in Their Apartment?

Article 19 of the Condominium Law (KMK) regulates the meticulous obligation of unit owners to protect the main structure and its integrity. Accordingly, no unit owner may interfere with the load-bearing system of the main structure (columns, beams, foundations, main walls) or undertake construction, repair, installation, or alteration in common areas without the consent of all unit owners. Even works carried out within their own independent section cannot be of a nature that would harm the main structure. For the legal text, you can refer to the mevzuat.gov.tr page of Condominium Law No. 634.

Examples of Unauthorized Renovations

Cutting, drilling, or weakening load-bearing columns/beams,

Changes to the exterior facade contrary to the management plan (door, window, air conditioner, combi boiler chimney),

Removal or enclosure of common walls or common areas,

Unauthorized additions/enclosed areas to the attic floor or common area,

Unauthorized changes to common water/electricity/heating installations.

Interference with the load-bearing system, in particular, leads to extremely severe consequences, as it poses a vital risk in terms of earthquake safety.

What Can Be Done Against Unauthorized Renovation?

The courses of action that can be taken in case of unauthorized renovation are as follows. First, a written warning is issued through the building manager, requesting the renovation to be stopped. If not remedied, a lawsuit for restoration to the previous state and cessation of interference can be filed in the civil court of peace; in urgent cases, the cessation of the renovation can be requested with a precautionary injunction. In cases that threaten life safety, such as interference with the load-bearing system, the relevant municipality/administration should also be consulted. If damage has occurred due to the renovation, compensation can be demanded.
