Tenant Makes Unauthorized Renovations in Turkey: Can the Foreign Landlord Demand Restoration? – 2026 Updated Guide

Can a foreign landlord demand restoration after unauthorized renovations in Turkey? Learn about written consent, repair costs, eviction and compensation remedies.

A foreign landlord may discover that a tenant has removed walls, changed flooring, installed fixtures, altered plumbing, replaced windows or made other renovations without permission.

The key question is whether the tenant had written consent and whether the alteration can remain without damaging the property or violating building rules. In many cases, a landlord may demand restoration, repair costs or compensation. However, restoration is not automatic in every dispute.

The result depends on the lease, the nature of the renovation, the condition of the property before the tenancy, any consent given by the landlord and the evidence available.

What Counts as an Unauthorized Renovation?

A renovation may be unauthorized when the tenant changes the property without the landlord’s required consent or exceeds the scope of permission that was granted.

Examples may include:

• Removing or constructing walls;
• Enclosing a balcony;
• Changing the layout;
• Removing doors or windows;
• Replacing flooring;
• Altering electrical systems;
• Changing plumbing;
• Installing built-in furniture;
• Replacing kitchen or bathroom fixtures;
• Installing air-conditioning equipment;
• Drilling into structural elements;
• Changing exterior surfaces;
• Adding signs or commercial equipment;
• Making changes to common areas.

Minor decoration may be treated differently from structural work. Painting a wall, hanging shelves or replacing removable furniture may not have the same legal consequences as removing a wall, changing plumbing or altering the building’s exterior.

The lease and the technical nature of the work should be reviewed before the landlord demands restoration.

Can the Foreign Landlord Demand Restoration?

Potentially, yes.

A landlord may demand that the tenant return the apartment to its previous condition when the tenant made unauthorized changes, caused damage or exceeded the landlord’s written consent.

The landlord may seek:

• Physical restoration;
• Removal of unauthorized fixtures;
• Repair of damaged walls, floors or systems;
• Replacement of removed items;
• Payment of restoration costs;
• Compensation for loss of use;
• Compensation for damage to the property;
• Eviction or lease termination where the breach is serious.

However, the tenant may argue that the landlord approved the work, accepted the renovation, knew about it and remained silent or benefited from the improvement.

The landlord should therefore avoid making assumptions and should preserve evidence of the original condition and the unauthorized work.

The Importance of Written Consent

Written consent is one of the most important issues in a renovation dispute.

The landlord should determine whether consent was given through:

• A signed lease clause;
• A separate written agreement;
• Email;
• Messaging applications;
• A property manager;
• A building management decision;
• An architect or contractor;
• A previous inspection report.

Consent may be limited. For example, a landlord may have approved painting but not the removal of a wall. Permission to install furniture may not authorize changes to plumbing or electrical systems.

If the landlord expressly approved the work, a restoration demand may be limited by the wording of that approval. The agreement may state whether the tenant must remove the improvement at the end of the lease or whether it will remain.

Renovations Made During the Lease

If the tenant is still occupying the apartment, the landlord should not enter by force or begin demolition personally.

The landlord may send a written notice requesting:

• An explanation of the work;
• Copies of permits or technical documents;
• Immediate cessation of unauthorized construction;
• Restoration of the property;
• Access for a lawful inspection;
• Repair of urgent damage;
• Confirmation that no further changes will be made.

If the renovation creates a safety risk or serious structural concern, an urgent technical inspection and interim court protection may be appropriate.

A serious and continuing breach may also support termination or eviction proceedings. Whether termination is available depends on the lease, the severity of the alteration, the possibility of correction and the applicable procedure.

Renovations Discovered After the Tenant Leaves

Restoration claims commonly arise after the tenant returns the keys or is removed from the property.

The landlord should inspect the apartment immediately and preserve:

• Move-in photographs;
• The original inventory;
• Handover records;
• Before-and-after videos;
• Repair estimates;
• Expert reports;
• Contractor invoices;
• Communications with the tenant;
• Evidence of removed fixtures;
• Evidence of unauthorized construction.

The landlord should not carry out major repairs before documenting the condition unless immediate work is necessary to prevent further damage.

If urgent repairs are required, the landlord should photograph the damage, preserve removed materials where practical and keep all invoices.

Structural Alterations and Building Safety

Structural changes require special attention.

Removing a wall, changing load-bearing elements, altering plumbing, modifying electrical systems or affecting the exterior may create risks for neighboring apartments and the building as a whole.

The landlord may need to consider:

• An urgent technical inspection;
• An expert report;
• Building management records;
• Insurance notification;
• A request to stop further work;
• Interim court protection;
• Restoration by qualified contractors;
• Separate administrative or safety procedures.

The landlord should not personally demolish a potentially unsafe structure. Work should be performed by qualified professionals after the legal and technical position is assessed.

How Can the Landlord Prove the Original Condition?

The strongest restoration claim compares the apartment’s condition before and after the tenancy.

Useful evidence may include:

• A signed condition report;
• An inventory;
• Move-in photographs;
• Earlier valuation reports;
• Purchase records;
• Prior repair invoices;
• Building management documents;
• Witness statements;
• Messages discussing the apartment;
• Previous inspection reports;
• Insurance photographs.

If no formal handover report exists, the landlord may still rely on witnesses, photographs, videos, contractor records, property advertisements and other evidence.

The absence of an initial report does not automatically defeat the landlord’s claim, but it may make the dispute more difficult.

Repair Costs and Compensation

The landlord may claim reasonable restoration and repair costs caused by the unauthorized renovation.

The claim may include:

• Contractor fees;
• Material costs;
• Expert expenses;
• Removal of unauthorized fixtures;
• Replacement of damaged items;
• Cleaning costs;
• Repair of water or electrical damage;
• Restoration of walls and flooring;
• Loss of rental income;
• Compensation for loss of use.

The landlord should distinguish restoration from improvement. The tenant should generally not be charged for an unnecessary upgrade that leaves the property in a better condition than before.

Repair estimates should be detailed and supported by invoices where the work has already been completed. The landlord should avoid inflated estimates and duplicate claims.

Can the Security Deposit Be Used?

The security deposit may be relevant to restoration costs and other proven tenant obligations.

The landlord should prepare a written accounting identifying:

• The original deposit;
• Restoration expenses;
• Repair costs;
• Unpaid rent;
• Utility expenses;
• Cleaning costs;
• Amount returned to the tenant;
• Remaining balance.

The landlord should not automatically retain the entire deposit. Deductions should be connected to documented losses and should comply with the lease and applicable rules.

If restoration costs exceed the deposit, the landlord may pursue the remaining amount through negotiation, mediation, court proceedings or enforcement.

Can the Lease Be Terminated for Unauthorized Renovation?

A serious unauthorized renovation may constitute a lease breach and may support termination or eviction.

The landlord should assess:

• Whether the lease prohibits alterations;
• Whether written consent was required;
• Whether the work is structural;
• Whether the tenant caused a safety risk;
• Whether the renovation can be reversed;
• Whether the landlord gave a warning;
• Whether the tenant continues the work;
• Whether the property suffered damage;
• Whether the tenant has breached other obligations.

Termination is not always automatic. The landlord may need to send a notice, allow correction where required, attend mediation and file the appropriate court claim.

The landlord should not change the locks, remove the tenant’s belongings or demolish the renovation without following the lawful procedure.

Mediation and Court Proceedings

Many lease-related disputes involve a pre-litigation mediation stage before a court claim can proceed. The exact requirement depends on the claim and the type of tenancy.

Mediation may resolve:

• Restoration obligations;
• Payment of repair costs;
• Removal of fixtures;
• Return of keys;
• Lease termination;
• Eviction;
• Compensation for lost rental income;
• Release or accounting of the security deposit.

If mediation fails, the landlord may file a civil claim. The court may appoint or consider technical experts to assess the original condition, the nature of the renovation and the reasonable cost of restoration.

Interim Injunctions and Urgent Protection

An interim injunction may be considered if the tenant is continuing unauthorized work or the property faces immediate harm.

Urgent protection may be relevant where:

• Structural elements are being removed;
• Plumbing or electrical systems are being altered;
• Water damage is spreading;
• The tenant is damaging common areas;
• The renovation threatens neighboring units;
• Evidence is being destroyed;
• The tenant is transferring the property to another occupant.

An interim measure is temporary and does not finally decide the restoration claim. The applicant generally needs to show a credible legal claim, urgency and a serious risk of harm. Security may be required.

Foreign Landlord Living Abroad

A foreign landlord may often pursue a restoration and compensation claim without traveling to Turkey.

A lawyer acting under a properly prepared power of attorney may be able to:

• Review the lease;
• Inspect title and property records;
• Arrange an expert inspection;
• Send a written notice;
• Attend mediation;
• Request interim protection;
• File a restoration or compensation claim;
• Coordinate contractors;
• Pursue eviction;
• Follow enforcement after judgment.

The power of attorney may require authentication, legalization or an apostille, together with a reliable translation.

The landlord should provide the lawyer with all photographs, lease documents, inspection reports, contractor records and communications concerning the renovation.

Legal Remedies and Appeal Process

If the court rejects the restoration or compensation claim, the landlord may have appeal or review options depending on the type of decision and procedural stage.

An appeal may concern:

• Incorrect interpretation of the lease;
• Failure to consider written consent;
• Inadequate expert analysis;
• Incorrect assessment of the property’s original condition;
• Unsupported repair-cost calculations;
• Failure to distinguish improvement from restoration;
• Procedural errors.

If an interim protection application is rejected, the written decision should be reviewed immediately because procedural periods may begin from formal service.

After a final judgment, court-supervised enforcement may be required to collect restoration costs or obtain compliance.

2026 Practical Checklist

A foreign landlord should:

• Review the lease and all consent documents;
• Determine whether the work was decorative or structural;
• Preserve before-and-after evidence;
• Obtain a technical inspection where necessary;
• Document the property before repairs;
• Send a written notice;
• Avoid private demolition or forced entry;
• Complete mediation where required;
• Claim reasonable restoration costs;
• Account for the security deposit;
• Consider termination if the breach is serious;
• Request urgent protection where necessary;
• Use court-supervised enforcement after judgment.

Lawyer Fırat Fesih Kaya recommends separating three issues clearly: whether the renovation was authorized, what restoration is technically required and what financial loss was actually caused.
