Urban Transformation Construction Disputes in Turkey: Legal Guide for Foreign Owners (2026 Updated Guide)

A 2026 legal guide for foreign property owners facing urban transformation construction disputes in Turkey, including contractor delays, unfinished projects, defective apartments, smaller replacement units, allocation changes, additional payments, title risks and compensation claims.

Urban transformation can completely restructure a foreign owner’s property rights. An existing apartment or commercial unit may be demolished and replaced through a construction agreement under which the owner expects to receive a new independent unit after completion.

The process creates significant legal and financial exposure because the owner may surrender possession long before receiving the replacement property. During this period, disputes can arise over construction delays, apartment allocation, loss of square meters, construction quality, additional payments, technical specifications, title transfers, contractor insolvency and project abandonment.

For foreign owners living outside the country, these risks can be greater because important project developments may occur while the owner is abroad.

The most important principle is that a construction dispute should not be evaluated only by looking at the unfinished or defective building. The reconstruction agreement, its annexes, approved plans, allocation schedules, title records, owner decisions, subsequent amendments and actual construction must be examined together.

Lawyer Fırat Fesih Kaya assists foreign property owners and investors with construction and contractor disputes arising from urban transformation projects.

The Reconstruction Agreement Is the Foundation of the Dispute

Most construction disputes begin with one question:

What exactly did the contractor promise to deliver?

A well-drafted reconstruction agreement should identify the replacement apartment or commercial unit and define the contractor’s obligations in sufficient detail.

Important provisions may concern the floor, position, orientation, net and gross area, room configuration, ownership share, parking, storage, technical specifications, construction period, delivery date, temporary rent, delay penalties, additional payments, title transfers and contractor security.

The contract should be read together with all incorporated annexes.

A brief main agreement may contain little detail while the architectural plans and technical specifications contain the obligations that later become central to the dispute.

Apartment Allocation Disputes

One of the most sensitive disputes concerns which apartment the owner will receive.

A foreign owner may originally be allocated a high-floor front-facing apartment but later discover that the contractor intends to deliver a lower-floor rear-facing unit.

The contractor may argue that both apartments have approximately the same area.

That does not necessarily make them economically or contractually equivalent.

Floor, orientation, view, sunlight, privacy, layout and location within the building can materially affect value.

The first step is therefore to establish the original allocation through the contract, allocation schedule and architectural annexes.

Can the Contractor Change the Allocated Apartment?

Not automatically.

The contractor’s authority depends on the agreement and circumstances.

Some contracts permit technical project modifications, but a clause permitting necessary architectural adjustments should not automatically be interpreted as unlimited authority to redistribute valuable apartments among owners.

A minor technical modification is very different from moving an owner to an objectively less valuable property.

If the contractor claims that the owner accepted the change, the relevant amendment or consent document should be obtained and examined.

Loss of Square Meters

Another frequent dispute arises when the replacement apartment is smaller than expected.

The owner may believe that the former property was 140 square meters but receive a new apartment that appears substantially smaller.

The comparison must be made carefully.

The old property’s area, the contractual replacement area, the approved project’s area and the actual completed area should be identified separately.

Net area should not be compared directly with an old gross-area figure.

A professional technical measurement may therefore be necessary before calculating the shortage.

What If the Contract Guarantees a Specific Area?

A clear contractual provision can significantly strengthen the owner’s position.

For example, an agreement guaranteeing a minimum net area creates a different legal situation from an agreement merely referring to an approximate gross measurement.

Owners should check whether the area appears in the main contract, allocation schedule, architectural plan or another annex.

If the completed apartment does not correspond with the contractual specification, the discrepancy should be documented before unconditional acceptance.

Construction Defects After Delivery

The replacement apartment may be delivered on time but contain significant construction defects.

Common problems include water leakage, inadequate waterproofing, dampness, mold, defective insulation, cracked surfaces, plumbing problems, electrical defects, poorly installed windows, defective flooring and heating-system failures.

Common areas may also contain serious defects involving roofs, facades, garages, elevators and drainage systems.

The owner should distinguish between defective work and incomplete work.

This distinction can affect the legal remedy.

Owners Should Inspect the Property Promptly

Inspection after delivery is particularly important in construction disputes.

Visible defects should be documented as soon as possible.

Owners should prepare photographs, video and a detailed defect list.

For significant problems, an independent technical report can establish the nature, cause and required repair.

Hidden defects require particular attention because some construction failures become apparent only after rainfall, seasonal temperature changes or extended use.

When a later defect appears, the owner should act promptly rather than waiting until the damage becomes substantially worse.

Technical Specifications Can Determine Contractor Liability

A newly built apartment is not necessarily compliant simply because it can be occupied.

The contractor may have promised specific construction materials, insulation systems, windows, flooring, kitchen installations or other technical characteristics.

The completed building should be compared with those specifications.

If materially inferior products were substituted, the owner should preserve evidence identifying both the promised and installed materials.

A technical expert can be particularly important where the contractor argues that the substitute product is equivalent.

Late Delivery of the Replacement Apartment

Delay is another major source of disputes.

The contractor may promise delivery within a specified number of months but miss the deadline repeatedly.

The first question is when the contractual period began.

It may run from demolition, site delivery, issuance of the construction permit or another event.

Owners should therefore avoid calculating delay until both the contractual duration and triggering event have been established.

Can Owners Claim Compensation for Delay?

Potentially, depending on the contract and circumstances.

Delay can cause substantial economic loss.

An owner may continue paying for alternative accommodation.

An investor may lose rental income.

A commercial property owner may remain in temporary premises.

The contract may also contain a specific monthly delay penalty or require the contractor to continue paying temporary rent until actual delivery.

Each category of loss should be calculated separately and supported by evidence.

Contractual Rent Can Become Extremely Important

Many urban transformation agreements require the contractor to make temporary rental payments while construction continues.

The wording should be reviewed carefully.

A provision requiring payments for 18 months differs substantially from a provision requiring payment until actual delivery.

Where the contractor stops making payments after the originally expected construction period, the owner’s contractual rights should be examined rather than assuming the rent obligation automatically ended.

Bank records should be preserved to establish the payment history.

Contractor Delay Can Become Contractor Abandonment

Not every delayed project should be treated as abandoned.

However, prolonged inactivity can indicate a more serious problem.

Current Law No. 6306 contains a special mechanism for qualifying cases where, for contractor-attributable reasons, construction has not started within one year or construction has stopped and has not continued for at least six months with the workforce and equipment necessary to complete the project. Owners representing the required simple majority by shares may seek the statutory termination process. If the competent authority confirms the statutory circumstances, the contractor is given 30 days to start or resume qualifying work; failure can result in the construction agreements being deemed terminated.

This mechanism should be distinguished from ordinary contractual remedies for delay.

Terminating the Contractor Requires a Completion Strategy

Termination alone does not complete the building.

The old property may already have been demolished and the new structure may be partially constructed.

Before attempting to replace the contractor, owners should investigate the remaining construction cost, completion percentage, permits, contractor rights, transferred land shares, third-party sales, mortgages, security and availability of a replacement contractor.

A successful legal termination without a realistic financing and completion plan can still leave owners with an unfinished project.

Contractor Bankruptcy Creates Additional Risks

A delayed contractor may eventually experience severe financial distress or formal insolvency.

Owners should investigate warning signs early.

These can include substantial reduction in construction activity, unpaid subcontractors, repeated requests for additional money, pressure for early title transfers or attempts to sell contractor units rapidly.

Current title records should be checked.

Property rights, contractual claims and monetary claims may need to be treated separately if formal insolvency occurs.

Additional Payment Disputes

Another common conflict arises when the contractor demands additional money after construction begins.

The contractor may argue that material prices, labor costs or financing expenses increased unexpectedly.

Owners should not assume that every cost increase automatically creates an obligation to pay more.

The reconstruction agreement should be reviewed.

Does it contain a fixed-price structure?

Does it permit adjustments?

Under what circumstances?

How are additional costs calculated?

Has the owner already made payments beyond the original agreement?

The contractual basis should be identified before additional funds are transferred.

Owners Should Be Careful With “Construction Cannot Continue Unless You Pay” Demands

This statement creates significant pressure, particularly after the old building has already been demolished.

Nevertheless, the owner should investigate the contractor’s financial position and the legal basis for the requested contribution.

If additional financing is genuinely necessary and owners decide to contribute, payment should ideally be connected to documented construction requirements and measurable progress.

Sending substantial additional money without a completion structure may increase the owner’s loss without solving the project.

Title Transfers Can Create Serious Construction Disputes

Urban transformation contracts frequently involve the transfer of land shares or future units to the contractor as consideration for construction.

The timing of those transfers can be critical.

If the contractor receives its full economic consideration at the beginning while most construction remains unfinished, owners may lose important practical leverage.

For this reason, staged transfers connected to independently verifiable construction progress can provide stronger protection.

Owners should understand exactly what property rights are being transferred and when.

Mortgages and Third-Party Rights Must Be Monitored

A contractor experiencing financial difficulty may attempt to use its project rights to obtain financing.

Owners should monitor whether mortgages, attachments or other encumbrances appear.

A dispute that initially concerns only late construction can become substantially more complicated after third-party property rights arise.

Foreign owners should therefore obtain updated title information during serious contractor disputes rather than relying exclusively on the title position that existed when the agreement was signed.

Contractor Sales Should Also Be Monitored

The current urban transformation framework expressly regulates operations concerning contractor security and sales of independent units allocated to contractors according to construction progress. The Urban Transformation Directorate identifies these matters among its implementation responsibilities.

This makes project monitoring particularly important when a contractor experiencing financial pressure begins disposing of units.

Owners should determine what has actually been sold or transferred rather than relying on informal statements.

Owner Decisions and the Simple-Majority Rule

Construction disputes frequently involve disagreement among owners themselves.

Under the current official framework, once the risky-building determination has become final, the owners can meet regarding the new redevelopment application without waiting for physical demolition. Where unanimity cannot be achieved, decisions concerning the new application may be made by owners representing a simple majority according to registered ownership shares.

Foreign owners should therefore not assume that absence from a meeting prevents the redevelopment process from continuing.

At the same time, a collective majority decision should not automatically be treated as resolving every separate contractual dispute between an individual owner and contractor.

Owners Who Disagree With the Majority Face a Separate Procedure

Where the required majority approves the redevelopment arrangement, the applicable decision and agreement conditions must be communicated to owners who did not join.

Current official guidance describes notification through the prescribed methods and a 15-day period in the relevant procedure. If the dissenting owner does not join under the statutory conditions, the share-sale mechanism may follow.

This statutory mechanism should not be confused with later disputes concerning whether the contractor actually delivered the apartment promised under an executed agreement.

The 2026 Meeting Documentation Should Be Preserved

The implementing framework was further formalized in February 2026.

The Urban Transformation Directorate confirms that the amendment published on February 4, 2026 introduced documents including the Meeting Notification Form, the corresponding notification record, the Meeting Information Note and the Resale Notification Form.

These records can become important evidence where parties later disagree about what proposal was presented, what decision was made and whether a foreign owner received the relevant procedural information.

Project Changes Can Create Contractual Disputes

The architectural project may change after the reconstruction agreement is signed.

This can affect apartment dimensions, floor allocation, orientation, parking or common areas.

Administrative approval of a revised project does not by itself answer every contractual question between the owner and contractor.

The agreement should determine what modifications the contractor was authorized to make and whether owner consent was required for material changes.

The original project, revised project and final construction should therefore be compared.

Unauthorized Apartment Substitution

An owner may discover near completion that the contractor intends to provide a different apartment from the one originally allocated.

This should be investigated immediately.

The owner should obtain the original allocation schedule, revised schedule, approved plans and current title records.

If the promised apartment has already been allocated or transferred to another person, the legal position may become substantially more complicated.

Delay in investigating can allow additional third-party rights to arise.

Smaller or Less Valuable Replacement Property

Square meters are not the only measure of equivalence.

A replacement apartment may have almost the same area but significantly lower market value because it is on a lower floor, has inferior orientation or lacks the promised view.

Similarly, a commercial unit may lose valuable frontage despite retaining approximately the same floor area.

A professional valuation should therefore examine the complete economic difference rather than simply multiplying missing square meters by an average price.

Defective Common Areas Can Affect Every Owner

A technically satisfactory apartment can still lose value if the building’s common areas are defective.

Roof leakage, facade failure, garage flooding, elevator problems or incomplete landscaping can affect multiple owners.

Owners should identify whether the defect arises from an individual apartment or a common building system.

Where a project-wide defect exists, coordinated technical evidence may be more effective than repeated individual repairs.

Evidence Should Be Preserved Before Repairs or Changes

Construction evidence can disappear quickly.

A contractor may open walls, replace waterproofing, repaint surfaces or change installations.

Owners should therefore document serious defects before corrective work begins.

Photographs, video, technical reports, measurements and repair quotations can become important.

Where emergency repair is necessary to prevent further damage, evidence should be preserved as thoroughly as circumstances allow.

Be Careful With Handover Documents

After years of waiting, owners may be eager to obtain their keys.

The contractor may present a document confirming that the apartment was delivered fully, correctly and without defects.

Such documents should not be signed automatically.

The owner should first check the apartment, contractual allocation, dimensions, technical specifications and visible defects.

A broad release may also affect accumulated delay, rent or compensation claims.

Foreign Owners Should Review Powers of Attorney Carefully

Foreign owners frequently manage redevelopment through a representative.

The power of attorney should match the actual task.

Authority to obtain documents is different from authority to sign a reconstruction agreement.

Authority to attend an owner meeting is different from authority to transfer land shares.

Authority to collect keys is different from authority to waive compensation or accept defective construction.

Broad authority can create serious consequences if a representative signs an amendment, extension or settlement without the owner fully understanding its effect.

A Foreign Owner Living Abroad Should Maintain a Complete Digital Project File

The file should include the title records, reconstruction agreement, all annexes, technical specifications, original and revised architectural plans, allocation schedules, owner-meeting records, amendments and powers of attorney.

Construction-progress photographs should be dated.

Payment records should be retained.

Temporary-rent payments should be documented.

Any contractor request for additional money should be preserved.

Technical and valuation reports should also be stored together.

This allows a dispute to be assessed without reconstructing several years of project history after problems become serious.

Do Not Wait Until the Building Is Finished to Seek Legal Review

Early intervention can be significantly more effective.

An apartment-allocation problem may be easier to address before the disputed unit is transferred.

A title problem may be easier to manage before third-party rights arise.

A contractor-delay problem may be easier to restructure before formal insolvency.

A construction defect may be easier to prove before repairs destroy the evidence.

Foreign owners should therefore seek review when the risk becomes identifiable rather than waiting for final delivery.

2026 Practical Legal Strategy

The first priority is identify the exact contractual entitlement. Determine what apartment, area, quality, delivery date and associated rights the contractor promised.

The second priority is obtain the complete project documentation, including annexes, technical specifications, allocation schedules and approved plans.

The third priority is compare the contract with actual construction. Determine whether the problem concerns delay, defective work, incomplete work, unauthorized modification or several issues simultaneously.

The fourth priority is check current title records where the contractor has received land shares, sold units or experienced financial difficulty.

The fifth priority is preserve technical evidence early. Serious defects and construction progress should be independently documented.

The sixth priority is calculate financial loss carefully, separating contractual penalties, unpaid temporary rent, repair costs, value reduction and other provable losses.

The seventh priority is review every proposed amendment before signing. Extensions, revised allocation schedules and additional-payment agreements can materially change existing rights.

The eighth priority is investigate contractor security and project-completion protections before financial distress becomes irreversible.

The ninth priority is distinguish collective owner decisions from individual contractor-performance disputes. The statutory majority mechanism does not automatically answer every private contractual claim.

The tenth priority is develop a completion strategy before pursuing termination. Removing the contractor without determining how the project will be financed and finished can leave owners with a legally terminated agreement but an unfinished building.

The central principle is straightforward: urban transformation construction disputes should be managed before the owner’s contractual, technical and property-right position becomes more complicated. Foreign owners should monitor the project actively, preserve evidence, control title and payment risks and respond promptly when contractor performance begins to diverge from the agreement.

Frequently Asked Questions

1. What are the most common urban transformation construction disputes?

Common disputes involve contractor delays, unfinished construction, defective apartments, smaller replacement units, unauthorized apartment changes, additional payment demands, unpaid temporary rent, inferior materials, title transfers and contractor financial distress.

2. Can a foreign owner challenge a contractor during an urban transformation project?

Yes. Foreign ownership does not remove the owner’s contractual or property rights. The available remedy depends on the agreement, project stage and nature of the contractor’s breach.

3. Can owners claim compensation if construction is delayed?

Potentially. Contractual penalties, unpaid temporary rent and provable financial losses may become relevant depending on the agreement and circumstances.

4. What if the replacement apartment is smaller than promised?

The contractual area, approved project and actual professional measurement should be compared. Net and gross measurements should not be confused.

5. What if the contractor delivers a defective apartment?

The defect should be documented promptly. Depending on the circumstances, repair, reduction, damages or other available remedies may need to be considered.

6. Can the contractor demand additional money because construction costs increased?

Not automatically. The reconstruction agreement should be reviewed to determine whether additional payments are contractually permitted and under what conditions.

7. What if the contractor stops construction completely?

Law No. 6306 contains a special termination mechanism for qualifying contractor-attributable non-start or prolonged stoppage situations. Where the statutory requirements are established, the competent authority can give the contractor a final 30-day period before the relevant agreements are deemed terminated.

8. Can owners replace the contractor?

Potentially, but termination and replacement should be planned carefully. Remaining construction costs, permits, title transfers, security, third-party rights and the new contractor’s financing must be considered.

9. Can a foreign owner manage a construction dispute from abroad?

Yes. Proper representation can allow documents to be obtained, title records checked, meetings monitored and legal action taken. The power of attorney should be drafted according to the specific authority required.

10. What documents are most important?

The reconstruction agreement, technical specifications, allocation schedules, approved and revised plans, title records, meeting documents, amendments, payment records, contractor correspondence, construction-progress evidence, handover records and independent technical or valuation reports can all be important.

Legal Assistance for Urban Transformation Construction Disputes

Urban transformation construction disputes can involve much more than a delayed building.

The dispute may affect the owner’s replacement apartment, land share, title rights, temporary accommodation, additional payments, construction quality and ultimately the value of the owner’s entire investment.

Foreign owners should therefore avoid treating contractor problems as purely technical matters.

The contractual, property, financial and construction aspects should be analyzed together.
