Structures built on more than one parcel, with shared common areas and infrastructure planned together, are called a multi-parcel development. Articles 66–74 of the Condominium Law establish a management framework specific to these structures. In 2026, a significant change was made to this framework.

2026 change: not 4/5, but 2/3

With Law No. 7579, the phrase “four-fifths” in Article 70 of the Condominium Law was changed to “two-thirds.” Accordingly:

  • A single management plan covering all buildings and premises within a large-scale complex is drawn up, and this plan binds all unit owners.
  • To amend the management plan, the votes of two-thirds of the total number of independent units represented by the members of the general assembly of representatives of the collective structure are required.
  • Management-plan provisions on temporary management may be amended by the votes of two-thirds of the unit owners in the multi-parcel development area.

In addition, a paragraph added to the article provides that provisions of management plans that contradict this article do not apply. So if your management plan still says four-fifths, that provision no longer applies.

Why does it matter?

The four-fifths threshold was, in practice, almost impossible to reach in large multi-building complexes. Management plans that had not been updated for years and no longer met residents' needs stayed in force because of it. The two-thirds threshold makes updating a management plan realistic.

For large-scale complexes that have long postponed updating their management plan, 2026 is a good year to put the matter back on the agenda.

The three-tier board in a large-scale complex

Large-scale complex management does not run on a single board:

  • Block owners' assembly: Decides on the block's own affairs.
  • Block representatives committee: Represents the blocks on the same parcel.
  • Multi-building representatives committee: Decides on matters affecting the entire complex.

Unless the management plan provides otherwise, the block unit owners' assembly appoints a manager and an auditor for the block. Failing to clearly define which expense belongs to which tier is the most common accounting problem in large-scale complexes.

Meeting timing is different

While the ordinary meeting in classic condominium ownership is held within the first month of each calendar year, in multi-parcel developments assemblies meet at least once every two years at the times shown in the management plans; if no such time is specified, within the first month of the second calendar year.

Building accounting in layers

A "single pot" approach is not sustainable in a large-scale complex. Block expenses, island expenses and expenses belonging to the complex as a whole must be tracked separately, and each tier must be able to produce its own income and expense statement. Otherwise, disputes over one block's money paying for another block's expenses are inevitable.

Çözüm Hanem meets this need with a four-tier structure: Branch → Compound → Building → Unit. Each tier has its own cash account, its own budget and its own reporting. For details, see our solution for property-management companies.
