Residential and commercial leases in Türkiye that renew in October 2026 can see rents rise by no more than 31.49%, following the release of September inflation data by the Turkish Statistical Institute (TurkStat) on Oct. 5.
The ceiling is derived from the 12-month average change in the consumer price index (CPI). It was slightly lower than the 31.79% limit that applied to contracts renewed in September.
TurkStat data showed that consumer prices rose 1.84% month-on-month in September, while annual inflation eased to 29.73%.
How the rule works
Under Article 344 of the Turkish Code of Obligations, rent increases agreed for renewal periods of residential and workplace leases cannot exceed the 12-month average change in CPI. A temporary 25% ceiling on residential rent increases, introduced during the period of very high inflation, is no longer in force, so the same CPI-based limit now applies to both homes and businesses.
For example, a tenant paying 30,000 liras per month whose contract renews in October could face an increase of up to 9,447 liras, bringing the new rent to 39,447 liras. Landlords and tenants may agree on a smaller increase; the limit is a maximum, not an automatic rate.
The cap applies to rent increases at renewal of an existing lease. Rents for new contracts are set freely between the parties, which is why market rents for new tenancies can rise faster. The central bank's New Tenant Rent Index, which tracks rents on newly signed contracts, showed annual growth of 26.4% nationwide in August, with new-tenant rents up 34.5% in Istanbul, 28.3% in Ankara and 25.5% in Izmir over the same period. In other words, tenants who move into a new home in the largest cities have generally faced steeper increases than those renewing an existing contract.
The rate for leases renewing in November will be determined once TurkStat publishes October inflation figures.
