Rent Increase: Statutory Caps vs. Market Reality in Iran

Rent increases in Iran are governed by the Landlord and Tenant Relations Act (1997), which came into effect on 25 August 1997, and the more recent Law on Organizing the Land, Housing and Rent Market (2024). While the government attempts to stabilize the market through mandatory caps to manage persistent high inflation, the market reality often diverges significantly from these statutory limits.

1. The Statutory Rent Cap (2026-2027)

Under Article 7 of the Law on Organizing the Land, Housing and Rent Market (2024), the Iranian Supreme Council of Housing has the authority to set mandatory ceilings for rent increases upon contract renewal. For the 2026-2027 cycle, the following caps apply:

• Tehran: 25% maximum increase.
• Other Major Cities: 20% maximum increase.
• Smaller Towns: 15% maximum increase.

Contractually, these caps apply when a tenant wishes to extend an existing lease for the same property. If the landlord and tenant cannot agree on a figure within this cap, the Dispute Resolution Council (Shoray-e Hal-e Ekhtelaf) is the competent tribunal and generally enforces these limits.

2. Market Reality vs. Legal Ceiling

Despite the official caps, real-world increases in Tehran often range between 45% and 60% due to inflation. Landlords often bypass these caps via:

• Currency Indexing: Demanding a portion of the payment in foreign currency or gold (legally risky but common).
• Refusal to Renew: Claims that the landlord's family needs the unit (a legal ground for non-renewal under the 1997 Act).
• Rahn Conversion: Manipulating the Rahn (deposit) to Rent conversion ratio.

3. The Tracking Code (Kod-e Rahgiri) and Increases

Registering the rent increase in the National Real Estate Transactions System is mandatory. Any increase beyond the legal cap that is not registered and assigned a unique Tracking Code is not legally enforceable. If a tenant pays an illegal excess, they may theoretically sue for a refund of up to ten times the excess amount under recent housing market transparency laws.

4. Rahn-to-Rent Conversion (Tabdil)

The customary conversion rate (Tabdil) is fundamental to calculating increases. In 2026, the market rate is approximately 3% per month (or 36,000 Tomans of rent for every 1 million Tomans of Rahn), though this fluctuates with bank interest and inflation.
