Legal Limits on Rent Increases in Koşuyolu (Istanbul)
Rent increases are one of the most sensitive topics between landlords and tenants in Türkiye.
If not managed correctly, they can lead to:
❌ Tenant loss
❌ Legal disputes
❌ Income instability
Especially in high-demand areas like Koşuyolu, understanding the legal framework is essential for sustainable and secure rental income.
⚖️ 1. What Determines Rent Increase Rates in Türkiye?
In residential leases, rent increases are regulated by:
👉 Turkish Code of Obligations (Law No. 6098)
The key rule:
✔ Annual rent increase cannot exceed the 12-month average CPI (Consumer Price Index - TÜFE)
📌 This rate is officially announced every month.
📊 2. How Is the CPI Limit Applied?
Even if the lease agreement states a higher rate:
✔ The legal CPI limit still applies
Example:
✔ CPI: 50%
✔ Contract: 70%
📌 The valid increase is:
👉 50% (legal cap)
⏳ 3. The 5-Year Rule (Critical Detail)
After:
👉 5 years of tenancy
The landlord has the right to:
✔ Request a rent adjustment based on market value
✔ File a rent determination lawsuit
📌 At this stage:
👉 Market conditions override previous increase limits
📉 4. Temporary Legal Caps (Important Note)
At certain periods, the government may introduce:
✔ Temporary rent increase caps (e.g., 25% limit)
