The maximum rent increase rate in Türkiye for November 2025 has been announced as 37.15%.
The Domestic Producer Price Index (D-PPI) and the Consumer Price Index (CPI) inflation rates are announced during the first week of each month.
Once these figures are published, the rate at which rents can be increased also becomes clear.
According to the statistical data released on November 3, 2025, the CPI table determining the upper limit for rent renewals in October 2025 has been published.
According to the announcement by the Turkish Statistical Institute (TurkStat), the monthly Consumer Price Index (CPI) in Türkiye increased by 37.15% in October 2025 (it was 38.36% in September 2025).
The CPI rate for October is used as the basis for rent increases in November.
The comparative CPI increase table, which takes 2003 as the base year, is as follows:
-
Compared to the previous month: 2.55% (September 2025: 3.23%)
-
Compared to the same month of the previous year (October 2024): 32.87% (September 2025: 33.29%)
-
Compared to December of the previous year (December 2024): 28.63% (September 2025: 25.43%)
-
Based on twelve-month averages: 37.15% (September 2025: 38.36%)
The rate at which residential and commercial rents can be increased in Türkiye is calculated based on the twelve-month average change in the CPI.
Accordingly, in November 2025, the maximum allowable rent increase in Türkiye is 37.15%.
What Is the Legal Basis for the Rent Increase Rate?
According to Article 343 of the Turkish Code of Obligations,
“Except for the determination of the rental price, no changes can be made to the detriment of the tenant in rental agreements.”
Article 344, titled Determination of the Rent, further states:
“The agreement between the parties regarding the rent to be applied in renewed rental periods shall be valid on the condition that it does not exceed the rate of change in the consumer price index based on the twelve-month averages of the previous rental year. This rule also applies to lease agreements with a duration longer than one year.”
(With the amendment made by Law No. 7161, dated January 17, 2019, the expression “producer price index” in the first and second paragraphs was replaced with “twelve-month average change in the consumer price index.”)
If no agreement has been made between the parties,
the rent shall be determined by the court, considering the condition of the leased property, provided that it does not exceed the twelve-month average change in the consumer price index of the previous rental year.
Under this legal framework, the upper limit for rent increases is determined according to the twelve-month average CPI of the previous year.
Can Rent Be Increased Above the Legal Limit?
Following the amendment to Article 344 of the Turkish Code of Obligations on January 17, 2019,
the maximum rent increase limit has been defined as the twelve-month average of the Consumer Price Index (CPI).
According to the Inflation and Price Data Table published by TurkStat,
the maximum rate that can be used for rent increases in November 2025 in Türkiye is 37.15%.
A property owner cannot unilaterally impose a rent increase higher than this rate.
However, if both the landlord and tenant mutually agree, they may determine a rent increase above or below the legal limit.
