Urban Transformation Contractor Agreement in Turkey: What Should Property Owners Check? (2026 Updated Guide)

Before signing an urban transformation contractor agreement in Turkey, property owners should check the replacement unit, construction area, additional payments, completion date, rent, guarantees, title transfers, contractor default and termination provisions.

Why Is the Contractor Agreement So Important in Urban Transformation?

The contractor agreement is one of the most important documents a property owner will sign during an urban transformation project in Turkey. A risky-building determination may start the administrative transformation process, but the contractor agreement can determine the owner’s financial and property position for several years.

A poorly drafted agreement can create disputes concerning the size of the replacement apartment, floor allocation, additional construction payments, temporary rent, completion deadlines, technical specifications, parking areas, common areas, title transfers and contractor default.

The consequences can be particularly serious for foreign property owners who live abroad and cannot regularly monitor construction.

The current official framework also makes contractual review increasingly important because, where unanimity cannot be achieved, decisions concerning the new development can be made by the required simple majority calculated according to ownership shares. Owners who do not join the majority-approved arrangement may subsequently face the statutory dissenting-share procedure.

For this reason, Lawyer Fırat Fesih Kaya recommends treating the contractor agreement as a major real estate transaction rather than a standard document that should be signed simply because other owners have already accepted it.

Check the Contractor Before Checking the Contract

Property owners frequently focus exclusively on the wording of the agreement while ignoring the company expected to perform it.

Both matters are important.

Before signing, owners should investigate who will actually undertake construction, whether the contractor has the necessary authorization and qualifications for the contemplated project, and whether the company has the organizational and financial capacity to complete a development of that size.

Official guidance itself points property owners toward contractor authorization information and the relevant contractor information systems when evaluating contractors.

Owners should also consider the contractor’s completed projects, ongoing projects, delays, corporate structure and ability to finance construction.

An excellent contract cannot completely eliminate the commercial risk of choosing an incapable contractor.

Identify the Exact Property the Owner Will Receive

One of the most important provisions should identify the replacement independent unit with sufficient precision.

A clause stating merely that the owner will receive “one apartment in the new building” can create substantial uncertainty.

The agreement and its annexes should address, where applicable, the future unit’s floor, position, orientation, approximate net and gross area, room configuration, balcony, terrace, storage area and parking rights.

Where commercial premises are involved, frontage, entrance, visibility, ceiling height and permitted use can materially affect value.

If the final independent-unit number cannot yet be determined, the contractual allocation method should still be sufficiently clear to minimize future disputes.

Net Area and Gross Area Must Not Be Confused

Area disputes are among the most predictable problems in redevelopment projects.

A contractor may advertise or discuss a particular square-meter figure without making sufficiently clear whether it refers to net usable area, gross independent-unit area or another calculation.

The agreement should use clearly defined measurements.

If the owner currently has a large apartment but will receive a smaller replacement unit because of the new project’s architectural or planning constraints, that difference should be understood before signature.

Foreign owners should be especially cautious about relying on informal translations or sales-style brochures rather than the legally operative agreement and approved project documents.

Check the Floor, Orientation and Location of the Replacement Unit

Two apartments with similar areas may have very different market values.

A higher floor, open view, street frontage, garden position or particular orientation may materially affect value.

The agreement should therefore make the replacement unit identifiable rather than leaving allocation entirely to the contractor at a later date.

If the contractor needs flexibility because the architectural project has not yet been finalized, the agreement should define objective allocation principles and reasonable limits on changes.

A foreign owner should not discover after demolition that the former street-facing apartment has been replaced with a materially different unit merely because the original agreement was vague.

Check the Future Ownership Share

The future ownership structure deserves separate attention.

Owners often focus on the physical apartment and ignore the ownership share associated with it.

However, ownership shares can affect future legal and economic rights.

The agreement should therefore be reviewed together with the intended post-construction ownership structure and project documentation.

Where the redevelopment substantially changes the number, size or nature of independent units, owners should understand how the new ownership arrangement will be established.

Check Every Additional Payment Obligation

The agreement should clearly explain whether the property owner must make an additional payment to the contractor.

If payment is required, the amount should preferably be fixed or objectively calculable.

The payment schedule should also be linked to clearly identifiable dates or construction milestones.

Owners should be cautious about broad clauses allowing the contractor to request undefined additional amounts because of “increased costs,” “economic conditions,” “unexpected expenses” or similarly open-ended concepts.

Construction costs can change significantly during a long project. The contract should therefore allocate that risk clearly rather than leaving it entirely unresolved.

What Happens If Construction Costs Increase?

This should be addressed before signing.

If the agreed contractor consideration is intended to be fixed, the contract should make the allocation of cost-increase risk sufficiently clear.

If price adjustment is contemplated, the calculation mechanism should be objective and understandable.

The owner should know whether increases in labor, materials, financing costs, taxes or other project expenses can generate additional payment obligations.

A clause giving the contractor effectively unlimited authority to determine future additional costs can expose owners to serious financial uncertainty.

Check the Construction Start Date

The agreement should not focus only on the final delivery date.

It should also establish when the contractor must begin performing the project.

A project can be delayed long before physical construction starts because of architectural work, permits, financing, demolition arrangements or contractor inactivity.

The agreement should therefore address the relevant conditions preceding construction and the period within which the contractor must complete those stages.

Owners should avoid agreements that allow the contractor to keep the project inactive indefinitely without meaningful consequences.

Check the Completion and Delivery Deadline

A clear completion deadline is essential.

The agreement should explain when the construction period begins and what event constitutes completion.

These questions can create major disputes.

Does the period begin when the contract is signed?

When the building is vacated?

When demolition occurs?

When the construction permit is issued?

When the site is formally delivered?

These are materially different dates.

The contract should identify the triggering event rather than merely stating that the project will be completed “within 24 months” or another period without explaining when the clock starts.

Define What “Delivery” Actually Means

Physical completion and legally usable delivery are not always the same thing.

The agreement should address what documentation and legal status must exist when the replacement unit is delivered.

Depending on the project, issues concerning the construction permit, completion of the building, occupancy authorization and establishment of the final ownership structure may be significant.

Official guidance recognizes that completion of the redevelopment ultimately involves steps such as establishment of condominium easement or condominium ownership and obtaining the relevant occupancy documentation.

A contractor should not be able to characterize an unfinished or legally unusable property as fully delivered merely by handing the owner a key.

Check the Delay Penalty

A delivery date without an effective consequence for delay may provide inadequate protection.

The agreement should state what happens if the contractor misses the contractual completion date.

Depending on the negotiated structure, this may involve continued rent payments, contractual compensation, a penalty provision or other remedies.

The drafting should be clear enough to reduce later disagreement about when the delay began and what amount becomes payable.

A foreign owner who lives abroad should also establish how delay will be documented and how payments will be monitored.

Check Temporary Rent Payments

Demolition may leave an owner without use of the property for a substantial period.

The contractor agreement should therefore clearly address any contractual temporary-rent obligation.

The amount, payment date, commencement date and duration should be specified.

The contract should also explain whether rent continues automatically if construction is delayed beyond the expected completion date.

This contractual payment should be distinguished from any separate public assistance that may be available under applicable urban transformation programs.

Owners should avoid vague promises such as “reasonable rent will be paid during construction.”

What Happens If the Contractor Stops Paying Rent?

The agreement should address default.

If temporary rent is an important part of the owner’s financial planning, repeated non-payment should have clearly defined consequences.

The owner should understand whether unpaid amounts become immediately claimable, whether contractual penalties apply and whether serious or repeated non-payment can contribute to termination rights.

A contractor who cannot meet relatively modest interim obligations may also present a warning sign regarding the financial health of the overall project.

Check the Technical Specifications

The architectural promise is only one part of the project.

The agreement should be accompanied, where appropriate, by sufficiently detailed technical specifications.

These may address structural and finishing standards, doors, windows, flooring, heating, cooling, insulation, elevators, façade systems, electrical installations, plumbing, kitchen and bathroom materials, landscaping and common areas.

Brand references should be handled carefully.

If the contractor is permitted to substitute materials, the contract should establish an equivalent-quality standard rather than allowing unrestricted downgrading.

Marketing Images Are Not Enough

Computer-generated images can help owners visualize the project, but they should not replace contractual specifications.

An attractive rendering does not necessarily establish legally enforceable dimensions, materials or amenities.

If a swimming pool, gym, parking structure, garden, storage room or other feature materially influenced the owners’ decision, determine whether it appears in the binding project documents and contractual obligations.

Property owners should distinguish between promotional material and enforceable commitments.

Check Parking and Storage Rights

Parking and storage frequently become contentious after redevelopment.

The agreement should identify whether the replacement unit includes a designated parking space, shared parking right or no individual parking entitlement.

The same applies to storage areas.

A promise that these matters will be “decided later” can create disputes once the new building contains fewer desirable spaces than owners expected.

Where these features materially affect value, they should be addressed before signature.

Check Common Areas

The redevelopment agreement should be reviewed together with the intended common-area structure.

Owners may need clarity concerning gardens, terraces, rooftops, parking areas, technical rooms and other common spaces.

Particular caution is required if the contractor intends to create new independent units or commercially exploit areas that owners previously regarded as common areas.

The economic structure of the redevelopment should be understood before owners approve it.

How Is the Contractor Being Paid?

In many redevelopment projects, the contractor’s consideration may involve money, new independent units, ownership interests or a combination of these.

Owners should understand the project’s economic model.

If the contractor will receive newly created apartments or commercial units, identify which units they are.

If ownership rights will be transferred during construction, understand when and under what conditions.

The contractor’s compensation structure directly affects the security available to property owners if construction fails.

Be Extremely Careful With Upfront Title Transfers

One of the most important contractual risks is transferring valuable ownership rights before the contractor has completed sufficient performance.

If substantial title interests are transferred early and the contractor later becomes insolvent or abandons construction, owners may face complex litigation and recovery problems.

A safer contractual structure may involve staged transfers linked to objectively verifiable construction milestones and appropriate security, depending on the project.

The exact mechanism should be designed according to the transaction.

Owners should understand that a promise to “start construction immediately” is not equivalent to legal protection for property already transferred.

Check the Contractor Security

Security should be analyzed before the agreement is signed.

The current regulatory framework includes security requirements in relevant redevelopment applications, and official reporting confirms that contractor security requirements have been an active part of recent regulatory adjustments.

However, statutory or administrative security requirements should not automatically be assumed to eliminate every private contractual risk.

Owners should determine what security exists, who can benefit from it, under what circumstances it can be enforced and whether additional contractual protection is appropriate.

The security package should be considered together with the project’s size and the value of the rights owners are transferring.

What If the Contractor Becomes Insolvent?

The contract should anticipate this possibility.

A financially healthy contractor at the beginning of the project may encounter difficulties later.

The agreement should therefore address serious default, prolonged suspension of construction, insolvency-related events and abandonment of the site.

Owners should understand when they can terminate, what happens to unfinished construction, what happens to transferred ownership interests and what documentation the contractor must return or provide.

Waiting until insolvency occurs to consider these questions is considerably more dangerous.

Check the Termination Provisions

A redevelopment agreement should define material breach and termination consequences.

Owners should know whether they can terminate if construction never starts, stops for a prolonged period or materially falls behind schedule.

The contract should also address contractor breaches involving unpaid rent, failure to obtain required approvals, unauthorized project changes or failure to provide agreed security.

Termination provisions should be realistic.

A theoretical termination right that can only be exercised after years of inactivity may provide little practical protection.

What Happens After Termination?

This question is just as important as the right to terminate.

If the agreement ends, who controls the construction site?

What happens to project documents?

What happens to permits?

Can another contractor continue the project?

What happens to ownership interests previously transferred?

What claims remain between the parties?

A contract that says only “the owners may terminate” without addressing the consequences may leave major issues unresolved.

Check Whether Previous Contractor Agreements Exist

Property owners should determine whether the property is already subject to another construction or redevelopment agreement.

This can become particularly important where an earlier contractor failed and owners are now negotiating with a replacement contractor.

Existing contractual annotations, title records and previous agreements should be reviewed before a new arrangement is executed.

In some transformation contexts, official procedures also address previously executed construction agreements and the consequences of their termination.

A new contractor should not be appointed without understanding the legal status of the old agreement.

Check Planning and Construction Assumptions

A contractor may make optimistic statements about the number of floors, total construction area or number of new units.

Owners should not rely solely on verbal assurances.

The economic feasibility of the agreement may depend heavily on what can legally be constructed.

If the contractor’s promised consideration assumes development rights that do not actually exist, the entire project can become financially unstable.

Planning status, architectural feasibility and permit assumptions should therefore be examined before owners agree to a distribution model.

What If the Final Permit Allows Less Construction Than Expected?

The contract should allocate this risk.

Suppose the parties expect a particular development size but the legally approved project ultimately allows less.

Who bears the reduction?

Are owners’ replacement units reduced proportionally?

Does the contractor receive fewer units?

Can additional money be requested?

Can either party terminate?

These questions should be answered in the contract rather than left for negotiation after the old building has already been demolished.

Check Contractor Authority to Change the Project

Some flexibility is inevitable during architectural and permit procedures.

Unlimited flexibility is not.

The contract should distinguish between minor technical modifications and material changes affecting an owner’s property.

A contractor should not be given unrestricted authority to materially reduce the apartment, change its floor, alter its orientation or remove important amenities without an agreed mechanism.

Foreign owners should pay particular attention to clauses allowing changes without further approval.

Check Force Majeure Clauses

Force majeure provisions can significantly affect completion deadlines.

The agreement should define what events qualify and how they affect performance.

Owners should be cautious about clauses that characterize ordinary commercial difficulties, routine cost increases or foreseeable contractor financing problems as automatic force majeure events.

The clause should also explain notification obligations and the extent of any time extension.

Otherwise, a broadly drafted provision may become a mechanism for indefinite delay.

Check Assignment and Subcontracting Rights

The owner should know whether the contractor can transfer the agreement, project or major obligations to another company.

A project approved because of one contractor’s financial strength and reputation may present very different risks if transferred to another entity.

The contract should therefore address assignment and significant subcontracting appropriately.

If consent is required for a transfer, the conditions should be clear.

Check Who Bears Taxes, Fees and Project Expenses

The contract should allocate project-related expenses clearly.

Ambiguity regarding permits, technical services, demolition, construction-related charges, project preparation and other expenses can generate later demands for money from owners.

The allocation should be reviewed against the applicable legal framework rather than relying solely on general wording that “all costs belong to the contractor.”

Check Insurance Obligations

Construction creates risks to workers, neighboring properties, existing structures and third parties.

The agreement should be reviewed for appropriate insurance obligations during demolition and construction.

Owners should understand which risks are insured, who must maintain coverage and what happens if the contractor allows the required policy to lapse.

Insurance is not a substitute for contractual responsibility, but it can form an important part of the project’s risk-management structure.

Check Defect Liability After Delivery

The owner’s legal problems do not necessarily end when the keys are handed over.

Construction defects may appear after occupation.

Water intrusion, façade defects, insulation failures, mechanical problems, common-area defects and workmanship issues can emerge later.

The agreement should therefore be examined for procedures concerning defect notification, repair obligations and post-delivery responsibilities.

The owner should also preserve delivery and inspection records.

Consider an Independent Technical Inspection

Legal review and technical review serve different purposes.

A lawyer can analyze contractual risk, but technical professionals may be needed to assess architectural plans, specifications, structural matters, progress percentages and construction quality.

For significant projects, owners should consider whether independent technical monitoring is appropriate.

This can be especially useful where contractual payments or title transfers depend on construction milestones.

The milestone should be objectively verifiable rather than determined solely by the contractor.

Foreign Owners Should Check Representation Powers

A foreign owner living abroad may participate through an appropriately authorized representative, but the power of attorney should be examined carefully.

Authority to attend an owner meeting does not necessarily need to include unrestricted authority to sell property, transfer title or accept unlimited additional payment obligations.

Likewise, authority to negotiate a contractor agreement should be distinguished from authority to sign it.

Foreign owners should understand precisely which rights they are granting before executing a power of attorney.

Do Not Sign a Contract You Cannot Understand

Foreign owners should obtain a reliable understanding of the legally operative agreement before signing.

A short verbal explanation from the contractor or another owner is insufficient for a transaction involving valuable property.

The owner should understand the replacement unit, financial obligations, project schedule, security, default provisions and title-transfer structure.

If translations are used, they should assist the owner in understanding the binding document rather than replacing legal review of the operative contractual text.

What If the Majority Has Already Approved the Contractor Agreement?

The owner should act quickly but should still review the agreement carefully.

Under the current framework, where unanimity cannot be achieved, the relevant new-development decision may be taken by the required simple majority calculated according to ownership shares.

The majority-approved decision and the agreement conditions, or information identifying where the offer can be examined, must then be communicated to owners who did not join the decision. Current official guidance provides for notification through a notary or a fifteen-day local administrative announcement, with additional electronic communication where applicable.

This means a dissenting owner cannot safely ignore the agreement merely because it contains unfavorable provisions.

The contractual risks and the statutory consequences of remaining outside the majority must be evaluated together.

What Happens If the Owner Refuses to Sign?

Refusal does not automatically stop the redevelopment.

Where the required majority has approved the new development and the statutory procedure is properly followed, a non-participating owner’s land share can ultimately become subject to statutory sale.

The owner should therefore avoid two opposite mistakes.

The first is signing an unsafe agreement simply because the majority demands it.

The second is refusing the agreement without understanding the statutory consequences.

The appropriate strategy is to review both the contractor agreement and the legality of the majority process before deciding how to proceed.

Check the Majority Before Accepting Pressure to Sign

Owners should verify whether the claimed majority actually exists.

Current official guidance confirms that the relevant majority is calculated according to registered ownership shares rather than simply the number of apartments or individuals supporting the project.

The title records should therefore be compared with the meeting documentation.

This can be particularly important where there are co-owners, inherited properties, recent transfers or unusual ownership-share structures.

A contractor’s statement that “almost everyone has signed” does not itself establish the statutory majority.

2026 Practical Legal Strategy

Before signing an urban transformation contractor agreement, the owner should first investigate the contractor and confirm that the proposed project is realistically capable of being completed. Official guidance provides mechanisms for checking relevant contractor authorization information, but regulatory eligibility should not replace broader commercial due diligence.

The replacement independent unit should then be defined as precisely as possible. Area, floor, orientation, parking, storage and other value-sensitive characteristics should not be left unnecessarily uncertain.

Every additional payment obligation should be identifiable. The contract should allocate construction-cost increases rather than leaving owners exposed to undefined future demands.

The construction period should have a clear starting point and completion event. Delivery should not be defined so loosely that an unfinished or legally unusable property can be treated as completed.

Temporary rent and delay consequences should be addressed expressly.

The technical specifications should be detailed enough to make construction quality objectively assessable.

The contractor’s compensation and any title-transfer mechanism should be understood before ownership rights are transferred. Early or uncontrolled transfers deserve particular caution.

Contractor security should be examined together with contractual protections. Recent official materials confirm that contractor security remains part of the regulatory architecture for relevant transformation applications.

The agreement should anticipate insolvency, prolonged delay, abandonment, termination and the consequences of termination.

Planning and permit assumptions should be independently checked where they are fundamental to the project’s economic structure.

Foreign owners should ensure that powers of attorney do not unintentionally authorize broader property transactions than necessary.

Finally, where a majority-approved agreement already exists, the owner must evaluate contractual objections together with the statutory dissenting-owner procedure. Under the current framework, a valid simple-majority decision followed by the prescribed notification can ultimately lead to sale proceedings against the share of an owner who remains outside the agreement.

The central principle is straightforward: the safest urban transformation agreement is not merely the agreement offering the largest replacement apartment or highest temporary rent. Property owners should evaluate whether the project can actually be completed, whether their replacement property is clearly protected, whether payments and deadlines are predictable, whether adequate security exists, and what happens if the contractor fails.

Frequently Asked Questions

1. What is the most important clause in an urban transformation contractor agreement?

There is no single clause that protects the owner. The replacement unit, additional payments, construction period, temporary rent, contractor security, title-transfer structure, default provisions and termination consequences should be reviewed together.

2. Should the exact replacement apartment be written into the agreement?

The replacement property should be identifiable as clearly as the project’s stage allows. Area, floor, orientation and other characteristics affecting value should not be left unnecessarily uncertain.

3. Can the contractor request additional money later?

This depends on the agreement and applicable legal circumstances. Owners should avoid vague clauses that allow undefined additional costs to be imposed unilaterally.

4. Should owners transfer title to the contractor before construction is completed?

Any title-transfer mechanism requires careful review. Early transfers can increase owner exposure if the contractor later defaults or becomes insolvent. Staged transfers and appropriate security may provide better protection depending on the project.

5. What happens if the contractor finishes the building late?

The contract should define the completion date and consequences of delay, including any continuing rent, compensation or contractual penalty arrangement.

6. What happens if the contractor becomes insolvent?

The consequences depend heavily on the contract, the construction stage, ownership transfers already completed and available security. Insolvency risk should therefore be addressed before signing.

7. Can the contractor change my replacement apartment?

The agreement should define what changes are permitted. Material changes to area, floor, orientation or other value-sensitive characteristics should not be left entirely to unilateral contractor discretion.

8. Can the majority approve a contractor even if I disagree?

Potentially, yes. Where unanimity cannot be achieved, the current framework permits relevant new-development decisions through the required simple majority calculated according to ownership shares.

9. Can my ownership share be sold if I refuse the majority-approved agreement?

Potentially, yes. If the required majority exists and the prescribed notification and dissenting-owner procedures are completed, the share of an owner who does not join the arrangement can ultimately become subject to statutory sale.

10. Should a foreign owner have the agreement reviewed before signing through a power of attorney?

Yes. The owner should understand the agreement before authorizing another person to sign it. Authority to attend meetings, negotiate, sign contracts and transfer property rights should be considered separately.

Legal Review of Urban Transformation Contractor Agreements

An urban transformation contractor agreement can determine the future value and security of a property owner’s investment. Once the existing building has been vacated and demolished, correcting a poorly drafted agreement can become substantially more difficult.

Property owners should therefore review the contractor, project feasibility, replacement-unit allocation, additional payment obligations, construction deadline, temporary rent, technical specifications, guarantees, title-transfer mechanism, default provisions and termination consequences before committing their property to the project.

For foreign owners, the need for careful contractual protection can be even greater because construction may continue for years while the owner remains abroad.
