Commercial Tenant Leaves Expensive Improvements Behind in Turkey: Who Owns Them After Lease Termination? (2026 Updated Guide)

What happens when a commercial tenant leaves expensive improvements, fixtures or renovations behind after terminating a lease in Turkey? Learn the rights of landlords and tenants regarding removal, compensation, restoration and ownership.

Commercial tenants in Turkey frequently spend substantial amounts renovating offices, restaurants, hotels, retail stores, warehouses and industrial premises. Problems can arise when the lease ends and the tenant leaves behind expensive improvements such as HVAC systems, electrical installations, partitions, flooring, lighting systems, kitchen equipment or customized infrastructure. The key question is whether those improvements belong to the landlord automatically, whether the tenant can remove them, whether compensation can be claimed and whether the landlord can instead demand restoration of the property. Under Turkish law, there is no single answer applicable to every improvement. The lease agreement, landlord’s consent, nature of the alteration, whether the item can be removed without damaging the property and the circumstances of termination can all materially affect the outcome.

Why Are Commercial Tenant Improvements Frequently Disputed?

Commercial properties are rarely delivered in exactly the condition required for a tenant’s business. Tenants may invest substantial amounts before opening their operations. A restaurant may install an industrial kitchen and ventilation system, while a foreign company leasing an office may construct meeting rooms, electrical infrastructure, security systems and specialized data facilities.

When the relationship ends, both parties may claim economic rights over those investments.

Start With the Commercial Lease Agreement

The lease agreement should be reviewed before analyzing individual improvements. Commercial leases frequently contain specific provisions governing alterations, additions, fixtures, restoration and compensation.

The contract may state that improvements remain with the property without compensation, require removal at the tenant’s expense or give the landlord discretion to request restoration.

Was the Landlord’s Written Consent Obtained?

Under the Turkish Code of Obligations, alterations and renovations made by a tenant are particularly connected with the landlord’s written consent.

Whether consent existed and precisely what it covered can therefore become one of the central questions in a later dispute.

Verbal Permission Can Create Evidentiary Problems

A tenant may claim that the landlord knew about and approved a major renovation, while the landlord argues that no legally sufficient consent was provided.

Emails, messages, renovation plans, correspondence with property management and signed protocols should therefore be preserved.

What Happens When Alterations Were Made With the Landlord’s Consent?

Where alterations or renovations were carried out with the landlord’s written consent, the restoration issue must be examined together with the applicable statutory rules and any written agreement between the parties.

The parties may also have specifically agreed on what happens to improvements at termination.

Can the Tenant Demand the Cost of Improvements?

Not automatically.

A tenant who spends a substantial amount renovating commercial premises should not assume that the landlord must reimburse the investment when the lease ends.

The existence of a compensation right depends heavily on the contractual arrangement and legal circumstances surrounding the improvement.

Increased Property Value Is Not Automatically the Same as Tenant Compensation

An improvement may significantly increase the market value of a property. That economic benefit does not by itself establish that the landlord owes the tenant the original construction cost.

The legal basis of the compensation claim must be analyzed separately.

Improvements and Movable Equipment Must Be Distinguished

Not everything installed inside leased premises becomes part of the property.

Freestanding machinery, furniture, computers, removable shelving, restaurant equipment and similar movable items may remain the tenant’s property.

Whether an item has become sufficiently integrated with the property can therefore be crucial.

Can the Tenant Remove Its Equipment?

Potentially, particularly where an item remains a movable asset belonging to the tenant and can be removed lawfully without unacceptable damage to the premises.

The lease should nevertheless be reviewed before removal because it may contain provisions concerning fixtures and improvements.

Removal Without Damage Is Important

A modular shelving system presents a very different issue from plumbing installed inside walls.

The more permanently an item has been integrated into the building, the more complicated the ownership and removal analysis can become.

Structural Improvements Require Special Attention

Structural modifications, permanent walls, staircases, extensive electrical systems and permanently integrated installations should be evaluated individually.

The parties should avoid treating every renovation item as belonging to one legal category.

HVAC Systems Can Become a Major Dispute

Commercial tenants sometimes install expensive heating, ventilation and air-conditioning systems.

Whether the tenant can remove the system may depend on its physical integration with the building, the lease terms, landlord consent and the damage that removal would cause.

Restaurant Improvements Are Particularly Complicated

Restaurant leases can involve ventilation shafts, grease traps, kitchens, gas infrastructure, electrical systems, refrigeration installations and decorative construction.

A detailed inventory should be created before surrendering the premises.

Factory and Warehouse Installations

Industrial tenants may install production machinery, cranes, racking, electrical infrastructure, compressed-air systems or specialized flooring.

The legal status of production equipment should be distinguished from improvements permanently incorporated into the building.

Office Fit-Outs Can Also Be Valuable

Foreign corporate tenants may invest heavily in glass partitions, raised floors, network infrastructure, access-control systems, generators and customized electrical installations.

The lease should determine as clearly as possible which elements can be removed at termination.

Can the Landlord Demand Restoration?

Potentially.

The landlord may claim that the property must be returned in the condition required under the lease and applicable law, taking account of contractual provisions, permitted alterations and ordinary deterioration resulting from proper use.

Whether restoration can be demanded for an authorized improvement requires careful examination of the written consent and contractual arrangements.

Ordinary Wear and Tear Is Different

Normal deterioration caused by proper contractual use should be distinguished from physical damage or unauthorized structural alterations.

A landlord should not automatically characterize every sign of commercial occupation as compensable damage.

Unauthorized Alterations Create Greater Risk

A tenant that substantially alters commercial premises without the required consent may face claims concerning restoration and damages.

This can be particularly serious where the alterations affect structural safety, common areas, building systems or legally regulated uses.

What If the Landlord Knew About the Renovation for Years?

Long-term knowledge may become factually relevant, particularly if the landlord actively participated in the project or benefited from the alteration.

However, factual knowledge should not automatically be treated as equivalent to every legal requirement concerning consent.

The complete correspondence should be reviewed.

Fit-Out Agreements Are Extremely Important

For high-value commercial leases, a separate fit-out protocol can prevent future disputes.

It can specify which works are permitted, who pays for them, which installations remain with the property, which can be removed and whether restoration or compensation applies.

What If the Lease Says All Improvements Become the Landlord’s Property?

Such clauses can have major consequences and should be analyzed according to their wording and applicable mandatory legal rules.

A tenant investing heavily in a property should review this issue before signing the lease rather than after termination.

What If the Lease Says No Compensation Is Payable?

Commercial leases frequently contain provisions addressing reimbursement for improvements.

The legal effect of the clause should be evaluated together with the circumstances of the particular lease and the nature of the expenditure.

Can the Tenant Remove Improvements Before Leaving?

The tenant should first classify the item and review the contract.

Removing permanently integrated improvements without legal analysis can result in significant property-damage claims.

Do Not Remove Installations Secretly

A tenant preparing to vacate should document the premises and, where a dispute is likely, communicate its position concerning valuable installations before dismantling them.

Removing disputed property immediately before surrender can complicate the evidentiary position.

Prepare an Improvement Inventory

The tenant should list significant investments and identify:

• the installation date;
• purchase and construction cost;
• landlord approval;
• invoices and payment records;
• contractor;
• photographs;
• whether the item is removable;
• estimated current value;
• and the contractual provision governing it.

This can significantly improve the quality of a later legal claim or defense.

Preserve Invoices and Construction Contracts

A tenant seeking compensation must first be able to establish what was actually spent.

Invoices, bank transfers, contractor agreements, architectural plans and completion records should be preserved.

Original Cost and Current Value May Be Different

A renovation costing a substantial amount several years ago may have depreciated significantly by termination.

Likewise, some improvements may increase the property’s current value even though their accounting value is low.

These concepts should not be confused.

Expert Examination May Be Necessary

Construction and valuation experts may be required to determine whether an installation can be removed, whether removal would damage the building, current value, restoration cost and the extent to which an improvement benefits the property.

Document the Property Before Handover

Both landlord and tenant should photograph and video the premises before keys are delivered.

High-value installations should be documented individually.

Prepare a Detailed Handover Protocol

A vague document stating only that “the premises have been returned” can create unnecessary litigation.

The protocol should record the condition of the premises, keys, meters, equipment, improvements, alleged damage and any reservations maintained by either party.

Be Careful With Waiver Language

A tenant should not sign a handover document stating that it has no further claims if it intends to pursue substantial compensation for improvements.

Likewise, the landlord should preserve unresolved restoration or damage claims where appropriate.

Security Deposits Can Become Part of the Dispute

Landlords sometimes attempt to deduct restoration expenses from the tenant’s security.

The legal basis and amount of any deduction should be documented rather than asserted generally.

What If the Landlord Keeps Valuable Tenant Equipment?

If movable equipment belonging to the tenant remains in the premises, ownership and possession issues should be addressed promptly.

The landlord should not automatically assume that every object left inside the property became landlord property upon termination.

What If the Tenant Abandons the Premises?

Abandonment can make the situation more complicated, particularly where valuable equipment remains.

The landlord should document the condition of the premises and obtain legal advice before disposing of valuable property.

Foreign Tenants Should Review Headquarters Records

Foreign companies sometimes close Turkish offices while invoices and fit-out agreements remain with an overseas parent company.

Relevant corporate records should be collected before employees, managers or local subsidiaries cease operations.

Sale of the Property Can Complicate the Issue

If ownership changes during the lease, records concerning improvements and landlord consent should be preserved.

The tenant should not assume that the new owner has detailed knowledge of arrangements made with the former owner.

Early Termination Requires Separate Analysis

Where a lease ends prematurely because of landlord or tenant breach, improvement losses may interact with broader contractual damage claims.

The reason for termination can therefore materially affect litigation strategy.

Improvements Made Shortly Before Termination

Large investments made immediately before an unexpected termination can create substantial financial disputes.

The tenant should preserve evidence explaining why the investment was made and what remaining economic life it was expected to have.

Unjust Enrichment Claims May Be Considered

Depending on the circumstances, a party may attempt to rely on unjust-enrichment principles where one side retains an economic benefit without an adequate legal basis.

However, such claims should not be assumed automatically where a lease agreement already regulates the relevant issue.

Contractual Claims Should Be Examined First

The lease and any fit-out agreement normally provide the starting point.

Only after understanding the contractual allocation of risk should additional legal bases be evaluated.

Limitation Periods Should Not Be Ignored

A tenant considering a compensation claim should not leave the matter unresolved indefinitely.

The applicable limitation analysis depends on the legal characterization of the claim and should be determined promptly.

Negotiated Settlement Can Be Commercially Efficient

Commercial improvement disputes can require expensive valuation and construction expertise.

Where ownership and value are genuinely disputed, parties may negotiate a settlement based on current value, removal cost and restoration expense rather than litigating every individual installation.

How Can Foreign Corporate Tenants Reduce the Risk?

Before signing a Turkish commercial lease, foreign companies should negotiate a detailed improvement clause covering landlord approval, ownership, removal, compensation and restoration.

High-value fit-outs should be governed by a separate written protocol.

How Can Commercial Landlords Reduce the Risk?

Landlords should require written approval before substantial modifications and specify what must happen at lease termination.

Inspection and handover procedures should also be agreed in advance.

2026 Practical Strategy for Existing Disputes

Where termination is approaching, neither party should wait until the final handover day. Review the lease, identify valuable improvements, obtain written evidence of consent, classify movable and permanently integrated items, assess restoration obligations and prepare a detailed photographic record.

Where the amounts are substantial, technical valuation before dismantling or surrender can preserve evidence that may otherwise disappear.

Frequently Asked Questions

Do all improvements automatically belong to the landlord after termination?

No. The legal position depends on the nature of the item, contractual provisions, landlord consent and whether it has become integrated with the property.

Can a commercial tenant remove improvements?

Potentially. Removable tenant-owned items may present a stronger case for removal, but the lease and physical consequences of removal must be considered.

Can the tenant demand reimbursement for renovation expenses?

Not automatically. The contractual and statutory basis for compensation must be established.

Can the landlord demand that the premises be restored?

Potentially, depending on the lease, nature of the alterations and circumstances under which they were made.

What if the landlord gave written permission for the renovation?

Written consent is highly important. Its exact wording should be reviewed to determine the parties’ rights concerning restoration and improvements after termination.

What if the tenant installed expensive machinery?

Machinery that remains movable should be distinguished from permanent improvements incorporated into the property.

Can the landlord keep equipment left behind?

Not automatically merely because the lease ended. Ownership and abandonment issues should be analyzed before valuable property is disposed of.

Should an expert inspect the property?

For expensive or technically complex improvements, an expert inspection can be extremely useful before removal or handover.

What documents should the tenant preserve?

The lease, fit-out agreement, landlord approvals, invoices, bank records, construction contracts, architectural plans, photographs and handover records should be preserved.

What is the most important step before returning the premises?

Prepare a detailed inventory of every valuable improvement and movable asset, determine the contractual and legal position for each one, and document the premises before anything is removed or the keys are surrendered.
