Reserve Building Area Designation in Urban Transformation: Impacts on the Right to Property and Actions for Annulment

In the urban transformation processes gaining rapid momentum across Turkey, one of the legal steps that causes the greatest concern for property owners is the formal designation of their real estate as a "Reserve Building Area" (Rezerv Yapı Alanı). This statutory authority, granted to the Directorate of Urban Transformation within the scope of Law No. 6306 on the Transformation of Areas Under Disaster Risk, renders it mandatory to establish a delicate balance between the constitutional right to property and the overarching public interest.

Specifically, the expansion of the definition of reserve areas following recent legislative amendments has sparked wide repercussions among civil society and real estate owners. As Malgır Law Firm, in this comprehensive article, we deconstruct in full legal detail the precise nature of reserve building areas, whether existing settled residential zones can be designated as reserve areas, their structural impacts on the right to property, and the statutory timeframes and requirements for filing an action for annulment against this administrative act under the framework of contemporary legislative provisions.

What is a Reserve Building Area? (Under the Framework of Law No. 6306)

Pursuant to Article 2 of Law No. 6306, a Reserve Building Area denotes specific geographic areas designated ex-officio or upon the request of TOKİ (Housing Development Administration) or the competent local Administration (Municipalities) by the Ministry of Environment, Urbanization, and Climate Change (or by the Directorate of Urban Transformation via delegated authority) to be utilized in urban planning applications executed under this Law.

Historically, these areas were defined strictly as "new residential zones"—generally consisting of vacant public lands located outside the city peripherals—whither citizens evacuated from risky buildings would be relocated. However, through a strategic legislative amendment, the phrase "to be utilized as a new residential zone" was explicitly struck from the statutory text.

Can Inhabited and Settled Residential Zones Be Designated as Reserve Areas?

Following the removal of the "new residential zone" restriction from the text of the statute, the answer to the most frequently raised question has become legally clear: Yes, "inhabited sectors" (meskun mahaller) containing active buildings, fully established neighborhoods, and settled residential orders can now legally be designated as reserve building areas.

The core objective of this legislative amendment is to clear the path for the administration to develop large-scale, project-based urban transformations within city centers. However, this structural shift introduces the severe risk that the real estate of property owners—who may currently reside in perfectly sound, earthquake-resistant buildings or wish to execute their own independent structural renovations—can be transferred directly under the unilateral control and disposal of the administration.

Impacts of a Reserve Building Area Designation on the Right to Property

The designation of an area as a Reserve Building Area within the scope of Law No. 6306 and its matching Implementing Regulation triggers exceptionally heavy administrative, legal, and material consequences for property owners. These structural outcomes are detailed below:

• Restriction of Disposal Powers: Upon the formal designation of a zone as a reserve building area, mandatory blocking annotations are recorded into the declarations column of the land register. Following these annotations, the property owners' powers of structural or commercial disposal over their real estate can be heavily restricted or entirely halted.

• The Administration's Project Development Monopoly: All operational procedures within the reserve area—including parcellation, the merger of plots (tevhit), subdivision (ifraz), allocations to public spaces, and new project design pipelines—transfer exclusively under the unilateral control of the Directorate or TOKİ.

• The Conversion of Real Property into Cash Equivalents (Expropriation or Forced Sale): To preserve overarching project integrity, the administration may seek a mutual agreement with the property owners. In the event that an agreement cannot be reached, urgent expropriation (acele kamulaştırma) procedures can instantly be executed, or the land shares can be sold via public auction based on fair market values, thereby permanently terminating the owner's title and right to property.

• Compulsory Evacuation and Demolition: Completely regardless of whether the specific buildings within the zone are structurally risky or sound, if the holistic transformation project demands it, the evacuation and physical demolition of the structures can be executed substantively ex-officio by the administration through administrative enforcement.

Actions for Annulment Against Reserve Area Designations and Statutory Timeframes

A reserve building area designation constitutes a direct "regulatory administrative act" (düzenleyici idari işlem) under administrative law principles. Property owners whose personal or material interests are violated can file an Action for Annulment (İptal Davası) before the competent Administrative Courts or the Council of State (Danıştay), asserting that the designation violates the law, the constitutional right to property, or basic empirical, scientific, and technical requirements.

Pursuant to the Administrative Judgment Procedure Law (İYUK) and Law No. 6306, the golden procedural rules that must be monitored with absolute precision throughout the annulment litigation are as follows:

• The Peremptory Window to Sue: The action for annulment must strictly be initiated before the Administrative Court within the statutory timeframe commencing from the date the administrative designation is officially published in the Official Gazette or personally served upon the individual co-owners (whichever occurs first). While the general statutory window to file an administrative lawsuit under the İYUK is 60 days, the rapid, specialized, and highly restrictive prescriptive periods executed under Law No. 6306 render the meticulous tracking of deadlines an absolute matter of legal survival.

• The Mandate of Empirical Scientific and Technical Vetting: Pursuant to the deeply settled jurisprudence of the Council of State, the materialization of an abstract administrative decree is entirely insufficient to legally sustain a reserve building area designation. The administration is under a strict legal burden to conclusively prove—via comprehensive, empirical, and scientific technical reports—the exact geological status of the area, its specific disaster risk potential, and the objective reasons why the zone cannot safely be preserved in its contemporary form. The absence, deficiency, or technical error of these scientific reports stands as one of the most powerful grounds for judicial annulment.

Requirements for Securing a Stay of Execution in Annulment Litigation

Because a reserve area designation equips the administration with the power to rapidly execute compulsory evacuations and physical demolitions, it is an absolute tactical necessity to formally request a Stay of Execution (Yürütmenin Durdurulması) immediately within the initiated action for annulment.

Pursuant to Article 27 of the İYUK, a judicial stay of execution can solely be granted if the following two statutory prerequisites materialize concurrently:

Prerequisite 1: Manifest UnlawfulnessPrerequisite 2: Irreparable HarmThe presence of a blatant, manifest violation of law in the adoption of the reserve area designation—such as an absolute lack of empirical technical reports, a clear absence of public interest, or a total usurpation of administrative power.The execution of the administrative act (the physical demolition of structures or the forced transfer of land titles) will cause the property owner to completely and irreversibly lose their real property, both physically and legally.

As a matter of procedural practice, the administrative courts routinely evaluate the concurrent existence of these two prerequisites based on the technical findings of an on-site judicial discovery (keşif) and an independent expert witness panel review, rendering the stay of execution order in accordance with that technical outcome.

Conclusion

Administrative decrees establishing reserve building areas under Law No. 6306 represent one of the heaviest and most invasive state interventions executed against the private right to property. Following the recent legislative amendments, the reality that even fully established, historically stable residential orders right in the city centers can be dragged into this regime renders it mandatory for property owners to defend their statutory rights in a significantly faster, aggressive, and highly professional manner.

Deficiently drafted petitions, missed prescriptive periods, or incomplete technical legal arguments can lead to the absolute and permanent forfeiture of real estate assets preserved across generations.
