How Is the Management Plan Amended and What Majority Is Needed?

A management plan is the "constitution" of an apartment or complex; it sets the basic framework from manager elections to dues sharing, from common area use to living rules. Over time, these rules may need to be amended. However, a management plan amendment is not made by an ordinary decision but by a high majority. The 2026 legal amendment brought an important novelty on this point. In this article we explain the current rules.

Why is a management plan not easy to amend?

The management plan is a contract registered in the land registry and binds all owners (including those who buy a unit later). Allowing basic rules to be amended easily by a minority or a simple majority would undermine stability. For this reason, the law requires a qualified majority to amend the management plan. The aim is to preserve the plan's reliability and durability.

Rule for apartments: 4/5 majority

For amendments in apartments consisting of a single structure, under Article 28 of the KMK, the votes of four-fifths (4/5) of all unit owners are required. The important point is that this ratio is not "of those attending the meeting" but of all owners. In a 20-unit apartment, therefore, the affirmative vote of at least 16 owners is required.

New rule in complexes: 2/3 majority (2026 amendment)

For complex properties, things changed in 2026. With Law No. 7579, published in the Official Gazette on 22 May 2026, the majority for amending the management plan in Article 70 of the KMK was reduced from four-fifths (4/5) to two-thirds (2/3). This change also applies to management plan provisions concerning transitional management.

The rationale of the amendment was practical: in large complexes with hundreds of independent units, reaching a 4/5 majority was almost impossible and amendments to management plans became effectively unusable. A new paragraph added to the law also provides that any provisions of management plans contrary to this ratio are no longer applied. Old plan clauses drafted by developers to make amendments harder are thus overridden.

The amendment process step by step

• Preparing the agenda: The article to be amended and the new wording are clearly determined.
• Call to meeting: The assembly of unit owners is called to a meeting in accordance with the procedure.
• Voting: 4/5 majority in apartments, 2/3 in complexes; the ratio is calculated over all owners.
• Recording in the decision book: The amendment is written into the book as a decision of the assembly of unit owners and signed.
• Registration in the land registry: The management plan amendment is registered in the land registry so that it becomes binding on everyone.

What if the majority cannot be reached?

If the required majority is not reached, the management plan cannot be amended and the existing plan remains in force. Amendments contrary to mandatory provisions of the law or infringing an owner's right of ownership are invalid even if the majority is reached; in that case, an action for annulment of the management plan may be filed. In some exceptional cases (for example, a partition action resolved by establishing condominium ownership), the court may intervene in the management plan.

Summary: A management plan is amended in apartments by 4/5 of all owners (KMK Art. 28) and in complexes by 2/3, following the reduction brought by Law No. 7579 (Official Gazette 22 May 2026). The ratio is calculated over all owners and the amendment must be registered in the land registry.

Frequently Asked Questions

How many votes do I need to amend the management plan in my complex?
With the 2026 amendment, two-thirds (2/3) of all owners is sufficient to amend the management plan in complexes. The old 4/5 rule was repealed.

Does 2/3 also apply in apartments?
No. The reduction to 2/3 is for complex properties. In single-structure apartments, a management plan amendment still requires a 4/5 majority (KMK Art. 28).

Is the old 4/5 clause in my management plan still valid for my complex?
No. Under the new law, provisions of management plans contrary to this ratio are no longer applied; the 2/3 rule now applies in complexes.
