The maximum rent increase rate that can be applied during lease renewal periods in Turkey is determined based on the 12-month average of the Consumer Price Index (CPI) announced by the Turkish Statistical Institute (TURKSTAT). For the August 2026 period, the 12-month average CPI announced by TURKSTAT stands at 31.90%. This rate will serve as the legal cap for both residential and workplace lease agreements.
Legal Cap on Residential Rent Increase: 31.90%
According to the regulation enacted in 2022, the rent increase rate for residential properties is linked solely to the 12-month average of the CPI. For August 2026, this rate stands at 32.04%. Unless otherwise agreed between the tenant and the landlord, the maximum rent increase allowed for the new period is capped at this rate.
Calculation Example (Residential)
- Current rent amount: 10,000 TRY
- Rent increase rate: 31.90%
- Yeni kira bedeli: 10.000 TL x 1,3190 = 13.190 TL
Current Situation in Commercial Rents
For commercial rents, the 12-month average CPI is generally taken into account as well. However, if a different rate has been specified between the parties in commercial contracts, that rate may also apply. Legal regulations and contract clauses should be carefully reviewed, and a written agreement should be established between the parties.
Calculation Example (Commercial)
- Current rent amount: 20,000 TRY
- Rent increase rate: 31.90%
- New rent amount: 20,000 TL x 1.3190 = 26,380 TL
Things to Conside
- The 31.90% rate is the legal cap on residential rent increases; rent cannot be raised above this rate
- In commercial rents, parties enjoy greater freedom of contract, but the CPI rate is generally accepted as the benchmark.
- The increase rate applies only to current contract renewals; market prices apply to new lease agreements.
- All increases must be documented in writing and officially, and payments should be made with a transaction receipt.
