January 2026 Rent Increase Rate Announced: The January 2026 rent increase rate has officially been clarified following the release of Turkey’s December 2025 inflation data.

According to the Turkish Statistical Institute (TÜİK), the legal maximum rent increase rate for residential and commercial leases renewed in January 2026 has been set at 34.88 percent, based on the 12-month average Consumer Price Index (CPI).

This rate applies to millions of tenants and landlords across Türkiye and represents the upper legal limit for rent increases.

How Is the January 2026 Rent Increase Calculated?

Under Article 344 of the Turkish Code of Obligations, rent increases are determined according to the 12-month average CPI rate announced by TÜİK. Landlords are not allowed to exceed this rate when renewing lease contracts.

While landlords may apply a lower increase, any demand above the CPI-based rate is considered illegal and may lead to legal disputes.

January 2026 Rent Increase Calculation Examples

Based on the 34.88% legal cap, rent increases are calculated as follows:

• Current rent: 10,000 TRY
  Increase: 3,488 TRY
  New rent: 13,488 TRY
• Current rent: 15,000 TRY
  Increase: 5,232 TRY
  New rent: 20,232 TRY
• Current rent: 25,000 TRY
  Increase: 8,720 TRY
  New rent: 33,720 TRY

Can Landlords Increase Rent Above 34.88%?

❌ No.
The 34.88% CPI-based rate is the legal ceiling for January 2026. Tenants have the right to reject any increase exceeding this limit and may seek legal protection if necessary.

Residential vs Commercial Rent Increases

• Residential rents:
  Subject strictly to the 12-month average CPI rate.
• Commercial rents:
  If no alternative rate is specified in the lease agreement, the CPI rate applies. However, commercial contracts may include special clauses.
