he maximum legal rent increase rate that can be applied during the renewal of residential lease agreements is determined based on the 12-month average Consumer Price Index (CPI) announced by the Turkish Statistical Institute (TURKSTAT). For March 2026, the 12-month average CPI announced by TURKSTAT is 33.39%. This rate represents the legal maximum increase that may be applied to residential lease agreements renewed during March.
How Is the Rent Increase Rate Calculated?
Following the regulations introduced in 2022, rent increases for residential properties are determined solely according to the 12-month average CPI. Commercial lease agreements may be subject to different legal regulations and contractual provisions. For residential leases, landlords cannot legally apply an increase exceeding the announced 12-month average CPI. However, both parties may mutually agree on a lower increase rate.
Applicable Rent Increase Rate for March 2026: 33.39%
The 33.39% 12-month average CPI announced by TURKSTAT is the legal maximum rent increase rate for residential lease agreements renewed in March 2026. This rate is established by the government to protect the rights of both tenants and landlords.
Calculation Example
Current monthly rent: TRY 10,000
Rent increase rate: 33.39%
New monthly rent: TRY 10,000 × 1.3339 = TRY 13,339
In this example, the highest legal monthly rent that may be charged after renewal is TRY 13,339.
Important Legal Considerations
- Residential rents may only be increased by up to the 12-month average CPI announced by TURKSTAT.
- Commercial leases may be subject to different contractual terms and legal regulations.
- This rate applies to lease renewals; newly signed lease agreements are generally determined according to current market conditions.
- All rent increases should be properly documented, and payments should be made through official banking channels with proof of payment.
