Understanding Rent Increases under Turkish Law
Under Article 344 of the Turkish Code of Obligations (TCO), rent increases in residential and commercial leases are capped by the 12-month average Consumer Price Index (CPI/TÜFE) published by TurkStat.
Legal Standards & Provisions
- Statutory CPI Ceiling: Even if a higher rate is written in the lease agreement, the statutory ceiling is capped by law.
- Expiration of 25% Cap: The temporary 25% residential rent cap expired on July 1, 2024. All leases follow CPI indexation.
- 5-Year Rule (TCO 344/3): After 5 years, either party can file a Rent Determination Lawsuit to align rent with market rates.
Frequently Asked Questions
Can a landlord demand an increase above the CPI average?
No. Under TCO Art. 344, unilateral increases exceeding the statutory CPI ceiling are invalid. Excess amounts paid can be legally recovered.
What is the difference between rent determination and rent adaptation lawsuits?
Rent determination (Art. 344/3) applies after 5 years to match market value. Rent adaptation (Art. 138) applies in extraordinary unforeseen economic circumstances.
