Kyrgyzstan-based investors and developers entering Türkiye's construction and residential development market often focus their due diligence on title, zoning, and tax exposure, while giving less attention to a clause that determines who pays when something goes wrong after handover: the construction warranty and defects liability regime. For anyone commissioning a build, buying off-plan, or acquiring a completed structure, understanding how Turkish law allocates responsibility for structural and material defects is essential before capital is committed.
How Turkish Law Frames Contractor Liability
Türkiye's Code of Obligations (Türk Borçlar Kanunu) governs construction contracts under the eser sözleşmesi (work contract) framework. The contractor is obligated to deliver a structure free of defects that would reduce its value, its fitness for intended use, or that deviate from agreed specifications. Where defects are found, the employer has several statutory remedies: demanding free repair, requesting a price reduction, or in serious cases, termination of the contract. These rights exist independent of what the contract says, though most professionally drafted agreements will restate and refine them.
Separately, and more consequential for structural risk, is the statutory liability period tied to the building's structural integrity. Under Turkish construction regulation, contractors and, in many cases, site supervisors and structural engineers, carry extended liability for load-bearing system defects, often running considerably longer than the general defects period applicable to finishes and installations. This distinction matters: a leaking roof and a compromised structural frame are treated very differently under the law, both in terms of the liability window and the severity of remedy available.
Practical implication : Contracts should separate structural defects from cosmetic or mechanical defects, with liability periods, escrow retentions, and remedy procedures defined for each category rather than treated as a single undifferentiated warranty clause.
Escrow, Retention, and Performance Bonds
Foreign investors accustomed to home-market practices should not assume Turkish contractors default to holding retention amounts or posting performance bonds. These protections exist in the market but must generally be negotiated and documented explicitly. A retention of five to ten percent of contract value, held until the defects liability period expires or a final inspection is passed, is a reasonable and commonly used structure. For larger developments, a bank letter of guarantee in place of cash retention is standard practice and preserves the contractor's working capital while still protecting the employer.
Building Inspection Firms and the Yapı Denetim System
Türkiye's mandatory building inspection system, administered through licensed yapı denetim firms, adds a layer of third-party verification during construction that does not exist in all comparable markets. These firms are legally distinct from the contractor and carry their own liability exposure for approving non-compliant work. For an investor, this means defect claims are not limited to the contractor alone. Where an inspection firm signed off on work that later proves defective, a separate line of liability may apply. This is worth understanding at the outset, since it affects who should be named in any dispute and how insurance or bond claims are structured.
Documentation Investors Should Insist On
Handover protocol : A signed, itemized handover report (teslim tutanağı) documenting the condition of the structure at delivery is the single most useful document in any later defects dispute. Its absence significantly weakens an investor's negotiating position.
As-built records : Final approved drawings, material certificates, and the yapı denetim firm's inspection reports should be requested and retained, not merely referenced as available on file.
Insurance confirmation : Where the project falls under mandatory earthquake insurance or all-risk construction insurance, investors should confirm the policy is active and that coverage extends through the defects liability period, not just through construction completion.
Dispute Resolution Considerations
Construction disputes in Türkiye can proceed through general courts or, where the contract provides for it, arbitration. For cross-border investors, including an arbitration clause with a clearly specified seat and governing rules is generally preferable to relying on default court jurisdiction, both for procedural predictability and for enforceability of any resulting award.
For Kyrgyz investors structuring a build-to-hold or build-to-sell project in Türkiye, the defects liability framework is not a boilerplate afterthought. It should be negotiated with the same attention given to price and schedule, since it determines who absorbs the cost when the structure itself, not just the paperwork, fails to perform as promised.
