What is Contractor Default in Urban Transformation?

In urban transformation projects, contractor default refers to the failure of a contractor to fulfill their obligations under the urban transformation contract or land-sharing construction contract within the stipulated time and in the proper manner. The most common instances of default include: failure to commence construction, delaying the licensing process, halting construction at a specific stage, abandoning construction, exceeding the delivery deadline, failure to pay rental assistance, manufacturing contrary to technical specifications, or failure to obtain the occupancy permit.

In urban transformation projects, contractor default has far more serious consequences than a simple breach of contract. This is because, in many cases, the risky building has been demolished, the owners' former independent units have disappeared, the property has become vacant land, and the owners' expectation of new housing or business premises is entirely dependent on the contractor's performance. If the contractor stops work at this stage, the owner faces not only a contractual delay but also loss of housing, income, rental burden, transfer of land share, title risk, and economic value loss.

In the Turkish Code of Obligations, a contract for work is a type of contract where the contractor undertakes to create a work, and the client undertakes to pay a price in return. In construction contracts in exchange for land shares, this price is often not money, but the transfer of land shares or independent units. Therefore, the contractor's default is evaluated both in terms of the provisions of the contract for work and the complex contract structure involving the transfer of immovable property. Article 470 of the Turkish Code of Obligations sets forth the basic definition of a contract for work.

In urban transformation contracts under Law No. 6306, contractor default is assessed under a special regime. This is because the implementing regulation of Law No. 6306 foresees special procedures regarding transformation processes in risky buildings, risky areas, and reserve building areas. The purpose of the implementing regulation is to determine the procedures and principles for the identification and demolition of risky buildings, transformation applications, and related processes.

Under what circumstances does contractor default occur?

In urban transformation projects, contractor default can manifest in various ways. Not every instance of default produces the same legal result; therefore, it is crucial to accurately determine which specific obligation the contractor has breached in each case.

The first instance of default is when the contractor fails to commence construction work after the contract is signed. This is especially problematic when a risky building has been demolished and the land is vacant, but the contractor fails to obtain permits, prepare a project, establish a construction site, or actually begin construction. This causes significant hardship for the property owners. Their former independent units have been demolished, but there is no real progress on the new construction.

The second type of default occurs when a contractor starts construction but abandons the project halfway through. Construction may stop at the foundation level, the rough construction phase, or at a specific floor level. In this case, the property owners' losses become even more complex. This is because there is not only an unfinished structure but also issues such as the cost of the work done by the contractor, transferred property deeds, sales to third parties, and the possibility of continuing with a new contractor.

The third type of default is exceeding the delivery deadline. The contract may specify a delivery period of 24, 30, or 36 months. If the contractor fails to deliver the units within this period, default occurs. However, the starting date of this delivery period is crucial. Does it begin from the contract date, the building permit date, the site handover date, or the demolition date? If this is unclear in the contract, determining default becomes difficult.

The fourth type of default is when the contractor fails to pay monetary obligations such as rent assistance, relocation costs, or late payment penalties. Rent assistance is one of the most important temporary safeguards for property owners in urban transformation projects. If the contractor cuts off or underpays rent assistance, the property owner may face serious economic hardship.

The fifth type of default is when the contractor fails to perform the work in accordance with the project, permit, or technical specifications. In some cases, this is considered defective performance; however, if the discrepancy is serious and subject to a time limit, it may fall under the provisions of default law.

Contractor's Default under Law No. 6306

In urban transformation projects, Law No. 6306 holds particular importance regarding contractor default. This is because contracts under this law include specific conditions allowing property owners to terminate the contract due to reasons attributable to the contractor.

In practice, two main situations stand out within the framework of Article 6/14 of Law No. 6306. Firstly, if, after reaching an agreement with all owners or after a decision by a simple majority of shareholders in proportion to their shares, the construction of the new building does not commence within one year due to reasons attributable to the contractor. Secondly, if the construction work is halted at a certain level and construction activity does not continue for a specific period to the extent necessary for the completion of the project. In this specific termination mechanism, the simple majority and the application process to the administration are crucial.

This special regulation aims to overcome the actual impasses in urban transformation projects. Because even if a risky building has been demolished and the owners' former independent units have been removed, the contractor may not have started the work or may have abandoned it. In this case, forcing the owners to resort only to traditional legal action could cause the project to drag on for years.

However, the administrative termination or contract termination process under Law No. 6306 is not automatic. It must be carefully examined whether the contractor's default truly originates from the contractor, whether the property owners have fulfilled their obligations, who is responsible for the permit and administrative obstacles, what the construction level is, and what terms the contract contains.

Can a decision to terminate a contract be made by a simple majority?

In urban transformation projects, the majority of property owners is crucial for terminating the contract in case of contractor default. In the current urban transformation system, a simple majority based on the proportion of property owners' shares is used in many transactions. In the practices of the Urban Transformation Presidency and related administrations, the simple majority is assessed based on land share or ownership ratio, rather than the number of property owners. The guidelines also state that sales and decision-making processes are conducted through the ARAAD Information System, linked to current land registry records.

When deciding to terminate a contract due to the contractor's default, the question "What is the total land share of these owners?" should be asked before asking "How many owners want this?". An apartment building might have 20 owners; 11 owners might want the contract terminated. However, if the total land share of these 11 owners does not exceed 50%, a simple majority may not be achieved. Conversely, if a smaller number of owners represent more than half of the total land share, a sufficient majority for decision-making may be reached.

The Ministry's provincial directorate announcement also states that the Implementing Regulation of Law No. 6306 was amended in the Official Gazette dated February 4, 2026, and numbered 33158. Therefore, in current files, especially regarding meeting, notification, majority, sale, and termination processes, the current legislation in effect at the time of the transaction must be checked.

A decision to terminate the contract by a simple majority does not give property owners unlimited freedom of action. The basis for the termination decision must be concrete; the contractor's default must be proven with documents. It must be demonstrated with technical and legal evidence that construction has not started, that construction has stopped, that there is a lack of personnel and equipment, that permit procedures have not progressed due to reasons attributable to the contractor, or that the delivery deadline has been exceeded.

How is a contractor's default proven?

If a contractor is alleged to be in default, this allegation must be supported by strong evidence. In urban transformation projects, contractor default cannot be proven simply by saying "the contractor is not doing the work." Property owners must prepare supporting documents and substantiate the default.

The first piece of evidence is the contract itself. The contract should be examined to include the start date of work, the licensing period, the delivery date, rent assistance, delay penalties, security deposits, and termination clauses. If the delivery period in the contract starts from the licensing date, the licensing date should be included; if it starts from the demolition date, the demolition date should be included; and if it starts from the handover date, the handover document should be included.

The second type of evidence is notarized notices. In most cases, it is important to issue a clear and unambiguous notice to the contractor, specifying which obligation has not been fulfilled and providing a reasonable timeframe. The notice serves as strong evidence in establishing default for future lawsuits or administrative applications.

The third piece of evidence is the technical inspection report. This report should detail the stage of construction, whether any activity is taking place on the site, the status of the team and equipment, completed and incomplete work, and include photographs and video recordings. If necessary, the court should be asked to provide further evidence.

The fourth piece of evidence is municipal and administrative correspondence. Has a permit application been submitted? Are there any missing documents? Why has the permit not been obtained? What stage is the project in? Is the building inspection process progressing? Are there any deficiencies in the municipal procedures caused by the contractor? These documents are crucial in determining who is attributable to the default.

The fifth piece of evidence is rental assistance and payment records. If the contractor promised to pay rental assistance but failed to do so, bank records, payment schedules, and warnings should be included in the file.

The contractor has not started construction

One of the most severe forms of default in urban transformation projects is when the contractor does not start construction at all. Especially if the building has been demolished, the owners' individual units have been removed, and the land is lying empty, the contractor's inaction directly affects the economic and social lives of the property owners.

If construction does not commence, the commencement condition in the contract should be examined first. If the contract states that "work will commence within 30 days from the date of the permit," the permit date must be determined. If it states "from the date of demolition and site handover," the demolition report and site handover document become important. If the time period is indefinite, the conditions of reasonable time, warning, and default are evaluated within the scope of the general provisions of the Turkish Code of Obligations.

In the context of the special termination procedure under Law No. 6306, the failure to commence construction of the new building within one year is a crucial threshold. However, the start of this one-year period can be assessed based on the specific date of the transaction, such as an agreement with the owners or a simple majority decision. Therefore, the calculation of the time period should be carefully considered before requesting termination.

The contractor may explain the delay in starting construction by citing issues with the municipality, permits, property disputes, or economic conditions. Whether these defenses are genuinely justified should be examined. If the permit delay stems from deficiencies in the contractor's project, the default may be attributed to the contractor. However, the assessment may differ if the permit delay is due to incomplete power of attorney from property owners, title deed issues, or a court decision.

The contractor abandoned the construction project halfway through

A contractor starting construction and then halting the work is a very common problem in urban transformation projects. In this case, the losses for the property owners are more complex because there may be an unfinished structure, completed works, transferred land shares, sales to third parties, and the possibility of continuing with a new contractor.

If construction is left unfinished, the first thing to do is to have the construction progress technically assessed. Has the foundation been laid? What is the level of the rough construction? Have the common areas been completed? What is the condition of the mechanical and electrical installations? Is the building permit valid? Is the building inspection process ongoing? These issues should be determined by a technical report.

Secondly, the reason for the halt in work should be investigated. Did the contractor abandon the project due to insufficient funding? Was there a stop order issued by the municipality? Were there problems with the building inspection firm? Is a project change awaited? Did the failure of the property owners to transfer their title deeds halt the work? The party responsible for the default will be determined based on this investigation.

Thirdly, the contractor should be served with a warning and instructed to cease operations. The warning should clearly state the obligations under the contract, the duration of the delay, the work not completed, and its consequences. If administrative termination under Law No. 6306 is to be pursued, the application file should be prepared with this evidence.

Delivery Delay and Late Payment Penalty

In urban transformation projects, the most common default by contractors is delivery delay. Property owners may have had their old buildings demolished and are awaiting delivery of their new units, but the contractor may have exceeded the delivery deadline. In this case, the provisions regarding delay penalties, rent assistance, and compensation in the contract become crucial.

The first issue in delivery delays is the start date of the delivery period. If the period is not clearly stated in the contract, the contractor may claim that the delivery period has not yet begun. Therefore, the date from which the delivery period will begin should be clearly defined when the contract is prepared. In the present dispute, the interpretation of the contract, the actual conduct of the parties, the permit date, the handover of the site, and the notices are examined together.

The second issue is what delivery means. Will the contractor be considered to have fulfilled their obligation simply upon handing over the keys, or is an occupancy permit also required? For the owners, true delivery means the independent unit is delivered in accordance with the contract, project, permit, and technical specifications, in a condition that allows for actual use.

If a late payment penalty is explicitly stipulated in the contract, the landlord can claim this amount. If there is no late payment penalty in the contract, the landlord can claim compensation under general provisions for lost rent, moving expenses, additional rent costs, financial losses, and other damages by providing proof. However, the presence of a clear and calculable penalty clause in the contract is more advantageous for the landlord.

Does non-payment of rent assistance count as default?

Yes. If the contractor has undertaken to pay rental assistance to property owners in the urban transformation contract, failure to fulfill this obligation may constitute default. Rental assistance is vital for meeting the housing needs of property owners after the demolition of a risky building.

Regarding rental assistance, the contract should clearly specify the payment start date, monthly amount, payment date, payment period, increase rate, and penalties for delay. If the contract states that "rental assistance will be paid during the construction period" but the period has been extended, it may be disputed whether the rental assistance will continue until the delivery date.

If the contractor has stopped paying rent assistance, the landlord should first send a written notice, demand the outstanding payments, and keep bank records. Legal action or enforcement proceedings may be initiated to recover the rent assistance. The failure to pay rent assistance along with a delivery delay constitutes a more serious breach of contract by the contractor.

Property Owners' Rights in Case of Contractor's Default

In the event of the contractor's default, the rights of the property owners vary depending on the content of the contract, the type of default, the construction level, and the scope of Law No. 6306. In general, the following rights may arise for the property owners:

The owner can, first and foremost, demand that the contractor fulfill their obligation. They can request that the construction begin, that any unfinished work be resumed, that incomplete work be finished, that the project be delivered, or that the rental assistance be paid.

The owner may demand a penalty or fine for delay. If the contract stipulates a monthly fee for delivery delays, that fee may be demanded. If there is no penalty clause, proof of actual damages is required.

The landlord may claim compensation for lost rent, overpayments of rent, financing costs, relocation expenses, and other damages. For these claims to be accepted, the damage, fault, default, and causal link must be substantiated.

The owner may pursue termination of the contract. If special conditions arise within the scope of urban transformation, an administrative application may be made under Law No. 6306. Otherwise, lawsuits for contract termination, cancellation and registration of title deeds, compensation, and liquidation can be filed in general courts.

Malik can demand the return of the land shares previously transferred to the contractor. However, the process becomes more complicated if the title deeds have been transferred to third parties. Therefore, it is crucial that the title deed transfer is stipulated in the contract as phased and conditional.

Termination of Contract and Administrative Appeal Procedure

In projects covered by Law No. 6306, a special termination procedure may be considered in case of contractor default. While this procedure seems more practical than a classic contract lawsuit, its conditions must be carefully evaluated.

For termination, an agreement must first be reached with all owners, or a decision must be made by a simple majority of owners in proportion to their shares. Furthermore, construction must not have commenced within one year due to reasons attributable to the contractor, or construction must have been halted at a certain level and activity not continued at a level necessary to complete the project. The fulfillment of these conditions must be proven with concrete evidence.

When submitting an administrative application, the following documents must be attached to the file: contract, title deeds, owner's decisions, majority land share calculations, warnings, technical inspection reports, municipal letters, photographs, rental assistance records, and all documents demonstrating the contractor's default.

The administration may reject the termination request if the application is incomplete. Furthermore, the contractor may argue that the delay is not their fault, that the property owners have not fulfilled their obligations, or that they were unable to continue the work due to administrative obstacles. Therefore, the contractor's potential defenses should be considered before submitting a termination application.

The Problem of Title Deed Return and Land Share Transfer

One of the biggest problems in case of contractor default is the fate of the land shares or independent units previously transferred to the contractor. If the title deeds were transferred to the contractor prematurely and the contractor has not completed the work, the owners may need to demand the return of the title deeds.

At this point, the provisions of the contract regarding the transfer of title are decisive. If the title transfer is tied to the construction level and the contractor has not reached the required level, the owners' claim for restitution becomes stronger. However, if the contractor has sold the shares to third parties, much more complex issues arise, such as the good-faith third party, the land registry, the annotation of the contract, and the nature of the transfer.

Therefore, when preparing urban transformation contracts, the transfer of title deeds must be done in stages. The transfer of land shares should not be made until the contractor reaches a certain construction level. Otherwise, in case of default, the owners may have to terminate the contract, return the title deed, and file lawsuits against third parties.

Why is gathering evidence important in contractor default cases?

In urban transformation projects, if a contractor is alleged to have defaulted, gathering evidence is often critical. Especially in cases such as unfinished construction, workmanship contrary to technical specifications, delivery delays, or cessation of operations, obtaining evidence through the courts strengthens the property owners' position.

In determining the evidence, the expert can identify the construction level, completed works, unfinished works, technical discrepancies, the status of activities on the construction site, the amount of work required to complete the project, and any defects. This report will then serve as primary evidence in subsequent lawsuits concerning termination, compensation, delay penalties, or the return of title deeds.

Issuing a direct termination notice without establishing evidence is risky in some cases. The contractor may argue that the construction progresses further than the owners claim, or that the delay is not due to their fault. A technical assessment will substantiate this argument.

Common Mistakes Made in Contractor Defaults

The most common mistake property owners make is remaining silent for a long time when the contractor defaults. Even when construction doesn't progress for months, rent assistance isn't paid, or the delivery deadline is exceeded, property owners failing to send notices and gather evidence makes the legal process more difficult later on.

The second mistake is relying solely on verbal discussions without a written warning. Telephone calls, meetings, and verbal warnings with the contractor are weak as proof. The process should be documented with a notarized warning or written notification.

The third mistake is to terminate the contract without determining the construction level. Since termination has severe consequences, acting without a technical assessment is risky.

The fourth mistake is failing to document all items of damage. Rent payments, moving expenses, bank loan expenses, business losses, additional accommodation expenses, and other losses must be proven with documentation.

The fifth mistake is delaying the establishment of a strategy to return the title deed if the title deed transfer has already taken place. Legal measures should be considered before the contractor transfers their shares to third parties.

Provisions to be Included in the Contract to Prevent Contractor Default

It is possible to seek legal recourse after the contractor's default is discovered; however, the strongest protection is established during the contract's drafting. Therefore, the following provisions must be included in the urban transformation contract:

The start date of the delivery period must be clearly stated. It should be explicitly noted whether the period begins from the permit date, the site handover date, or the demolition date.

Late payment penalties must be concrete and calculable. A monthly fee should be determined for each owner or each independent unit.

Rent assistance should be arranged separately. The payment amount, duration, start date, and whether it will continue in case of delay should be specified.

The transfer of title should be done in stages. The contractor should earn rights proportional to the work completed.

Security must be obtained. A bank guarantee letter, performance guarantee, or other strong collateral should be added to the contract.

The technical specifications must be detailed. They are the most important basis for disputes regarding defective workmanship.

The termination procedure must be clear. It should include provisions regarding notice, deadlines, default, foreclosure, return of title deeds, and liquidation.

The contractor's authority to sell to third parties should be restricted. Allowing the contractor to freely sell shares before the project is completed increases the risk for the owners.

Conclusion

In urban transformation projects, contractor default is one of the most serious legal and economic problems property owners may face. If the contractor fails to start construction, leaves the work unfinished, exceeds the deadline, fails to pay rental assistance, or does not comply with the technical specifications, the property owners' right to housing, property rights, and economic interests are directly harmed.

In this situation, property owners should not remain passive. First, the contract should be reviewed, delivery and commencement dates should be determined, a written warning should be sent to the contractor, the construction level should be technically assessed, rental assistance and damage items should be documented, a simple majority calculation should be made, and if necessary, administrative termination or general litigation procedures under Law No. 6306 should be evaluated.

In projects covered by Law No. 6306, if construction work is not started within one year due to reasons attributable to the contractor, or if construction activities are halted at a certain level, special termination mechanisms may come into play. However, in this process, the majority of owners, the calculation of land shares, the source of default, technical findings, and the administrative application file are of great importance.

In conclusion, contractor default in urban transformation is not simply a matter of "the contractor was late." It is a comprehensive legal crisis affecting contract termination, title deed return, compensation, delay penalties, rental assistance, selection of a new contractor, transfer of land shares, and administrative appeal processes. The most effective strategy is to include strong guarantees and clear sanctions during contract preparation; and when default occurs, to act quickly, with proper documentation, and in accordance with the law.
