How to Obtain a Building Permit — Conditions, Documents, and Process

A building permit (yapı ruhsatı) is the official authorisation document that must be obtained from the competent authority before construction of a building may begin. Pursuant to Article 21 of Law No. 3194 on Zoning (İmar Kanunu), a building permit is mandatory for all buildings within the scope of this Law. Severe sanctions are applied to buildings constructed without a permit or in violation of the permit. In this article we examine in detail the building permit process, the required documents, and the consequences of a permit-less building.

What Is a Building Permit and Why Is It Mandatory?

A building permit (yapı ruhsatı) is an authorisation document issued by the competent authority to ensure that a building is constructed in conformity with zoning legislation, the zoning plan, and relevant regulations. Pursuant to Article 21 of Law No. 3194 on Zoning (İmar Kanunu), no building may be constructed without a permit, and no substantial changes or alterations may be made to existing buildings.

The fundamental reasons why a building permit is mandatory are: ensuring the safety of life and property, ensuring that buildings are constructed in accordance with the Earthquake Regulation, maintaining urban order, planning infrastructure services, and protecting public health. Since a large part of Turkey lies in an earthquake zone, permit supervision is critically important for building safety.

Buildings constructed without a building permit are characterised as unauthorised/unlawful buildings (kaçak yapı) and, pursuant to Article 32 of Law No. 3194 on Zoning (İmar Kanunu), a building stop record (yapı tatil tutanağı) is drawn up and construction is halted. In addition, an administrative fine is applied pursuant to Article 42, and a demolition order may be issued for the building. These sanctions clearly demonstrate the importance of the building permit.

What Conditions Must Be Met to Obtain a Building Permit?

To obtain a building permit, the property must fall within the scope of the zoning plan; a zoning status certificate (imar durumu belgesi) must have been obtained; the architectural and structural projects must have been approved; a building supervision (yapı denetim) agreement must have been signed; and the necessary fees must have been paid.

The zoning status certificate (imar durumu belgesi) is the first step in the building permit process. This is an official document that shows the designated use of the property in the zoning plan and the conditions of development (floor area ratio — emsal, building coverage ratio — TAKS, total floor area ratio — KAKS, building height, setback distances, etc.). The zoning status certificate is obtained from the municipal department of zoning (belediye imar müdürlüğü) by applying with the block and parcel details of the property.

In addition, for a building permit application a building supervision agreement must have been entered into with a building supervision firm. Pursuant to Law No. 4708 on Building Supervision (Yapı Denetimi Hakkında Kanun), building supervision firms are responsible for supervising the implementation of the project and the quality of the building. A building permit is not issued without a building supervision agreement.

What Documents Are Required for a Building Permit Application?

For a building permit application, the following are required: title deed or land allocation certificate, zoning status certificate, architectural project, structural project, mechanical installation project, electrical project, ground survey report, building supervision agreement, and technical responsibility undertakings (fenni mesuliyet taahhütnameleri).

Details of the required documents are as follows: The title deed proves the ownership of the property. In the case of a jointly owned parcel, the consent of all co-owners is required. The zoning status certificate determines the development conditions of the property. The architectural project consists of drawings showing the internal and external layout, floor plans, elevations, and sections of the building. The structural project contains the calculations and details of the load-bearing system of the building.

The ground survey report (zemin etüdü raporu) is a report that reveals the characteristics of the ground on which the building will be constructed and is the basis for determining the foundation system. The mechanical installation project contains drawings of the heating, cooling, ventilation, and sanitary installation systems. The electrical project shows the electrical installation layout of the building. All projects must be prepared by engineers and architects registered with the relevant professional chambers.

How Does the Building Permit Process Work Step by Step?

The building permit process consists of the following stages: obtaining the zoning status certificate, preparing projects, signing the building supervision agreement, applying to the municipality, project review and approval, and issuing the permit. Pursuant to Article 22 of Law No. 3194 on Zoning (İmar Kanunu), the municipality is obliged to conclude the application within 30 days.

Step 1 — Obtaining the Zoning Status Certificate: An application is made to the municipal department of zoning to learn the zoning plan status of the property and the conditions of development. The zoning status certificate contains the parameters (floor area ratio, height, setback distances, etc.) that will be used as the basis for preparing the projects.

Step 2 — Preparing Projects: In conformity with the zoning status certificate, the architectural, structural, mechanical, and electrical projects are prepared by the relevant professionals. The projects must comply with the Planned Areas Zoning Regulation (Planlı Alanlar İmar Yönetmeliği) and the Earthquake Regulation (Deprem Yönetmeliği).

Step 3 — Building Supervision Agreement: Pursuant to Law No. 4708, an agreement is signed between the building owner and the building supervision firm. The building supervision firm reviews the projects and issues a conformity certificate.

Step 4 — Applying to the Municipality: An application is made to the municipal department of zoning with all projects, documents, and the building supervision conformity certificate. The necessary fees are also paid at the time of application.

Step 5 — Review and Approval: The municipality reviews the projects for compliance with zoning legislation. If deficiencies or discrepancies are found, the applicant is notified and asked to make corrections.

Step 6 — Issuing the Permit: If the projects are found to be adequate, the building permit is issued and construction may begin. The date of the permit is the basis for calculating the period for commencing construction. Pursuant to Article 29 of the Zoning Law, construction must be commenced within 2 years and the building must be completed within 5 years of the building permit being issued.

How Are Architectural Project Approval and Structural Project Supervision Carried Out?

Architectural project approval is the process by which the municipal department of zoning supervises the conformity of the project with the zoning plan, zoning regulation, and applicable legislation. Approval of the architectural project is one of the most critical stages of the building permit process; the project must comply with the conditions of development set out in the zoning status certificate.

Structural project supervision is the verification of whether the load-bearing system of the building complies with the Earthquake Regulation and applicable standards. Structural projects prepared in accordance with the provisions of the Turkish Building Earthquake Code (Türkiye Bina Deprem Yönetmeliği — TBDY-2018) are reviewed and approved by the building supervision firm. The structural project performs calculations for reinforced concrete, steel, or masonry construction systems, determines the foundation system, and evaluates the seismic performance of the building.

Common problems encountered during the project approval process include disputes concerning areas not included in the floor area ratio calculation, incorrect application of setback distances, exceeding the building height, and inadequate planning of car parking areas. Identifying these issues during the design stage shortens the permit process.

What Are the Sanctions for Building Without a Permit?

The sanctions for building without a permit are: drawing up a building stop record, halting construction, imposing an administrative fine, and ordering demolition of the building. Articles 32 and 42 of Law No. 3194 on Zoning (İmar Kanunu) regulate these sanctions in detail.

Pursuant to Article 32 of the Zoning Law, when a building without a permit or in violation of the permit is identified, the municipality or the governorate draws up a building stop record and immediately halts construction. The building owner is given 30 days to obtain a permit or remedy the discrepancy. If the necessary correction is not made within this period, an order to demolish the building is issued.

Pursuant to Article 42 of the Zoning Law, an administrative fine is applied to those who build without a permit or in violation of the permit. The fine is calculated based on the type, size, and nature of the violation. Fine amounts are increased annually at the revaluation rate. As of 2026, fines for buildings without a permit start at [TO BE VERIFIED] TL and may reach significant amounts depending on the size of the building.

What Is an Occupancy Permit (İskan) and How Is It Obtained?

An occupancy permit (yapı kullanma izni — iskan belgesi) is an official document certifying that a completed building has been finished in conformity with zoning legislation, its permit and projects, and authorising the building to be opened for use. Pursuant to Article 30 of Law No. 3194 on Zoning (İmar Kanunu), upon completion of the building in full, or for parts that may be used in part, it is mandatory to obtain an occupancy permit.

Documents required for an occupancy permit application: the building permit, the building supervision firm's completion certificate, a social security clearance certificate (SGK ilişiksiz belgesi), an energy performance certificate (enerji kimlik belgesi), a shelter report (sığınak raporu) if required, an elevator registration certificate (asansör tescil belgesi) if required, a fire department report (itfaiye raporu) if required, and façade photographs. The municipality inspects the building on site following the application and checks its compliance with the permit and projects.

As a rule, it is prohibited to use a building or to connect electricity, water, or natural gas without an occupancy permit. However, in practice many buildings without occupancy permits are in use. This situation carries serious legal and financial risks for the building owner. Where buildings without occupancy permits are sold, the land registry offices may carry out the transfer, but it is important that the buyer is aware of this situation.

What Are the Common Problems Encountered in the Building Permit Process and Their Solutions?

The most common problems encountered in the building permit process are: incompatibility of the property with the zoning plan, project deficiencies, the problem of consent in jointly owned parcels, the municipality failing to comply with time limits, and disputes with the building supervision firm. Obtaining legal support is of great importance in resolving these problems.

In the case of incompatibility of the property with the zoning plan, the designated use of the property in the zoning plan should be checked. It is not possible to prepare a residential project on a property allocated to a non-residential use (such as green space, road, or public service area). In this case, a plan amendment may be requested or a legal action for payment of expropriation compensation may be filed.

If the municipality fails to comply with the 30-day period prescribed by Article 22 of the Zoning Law, an administrative application may be made. Pursuant to Article 10 of Law No. 2577 on Administrative Procedure (İYUK), if the administration does not respond to an application within 60 days, the request is deemed to have been implicitly rejected and an action may be filed before the administrative court. A complaint may also be submitted to the mayor's office, through the governorate, or via the Presidential Communication Centre (CİMER).
