UAE Rent Increase Laws: Navigating RERA and Caps

The United Arab Emirates—specifically its leading real estate markets of Dubai and Abu Dhabi—implements strict rent control mechanisms to protect tenants from arbitrary and unsustainable rent hikes while balancing landlords' investment returns.

Dubai: The RERA Rental Index

In Dubai, landlords cannot increase rent simply because they want to. Rent increases are strictly governed by Decree No. 43 of 2013, enforced by the Real Estate Regulatory Agency (RERA).

The allowable increase is determined by comparing the tenant's current rent to the average market rent for a similar property in that specific community (as determined by the official RERA Rental Index calculator).

The Increase Tiers

When calculating a rent increase upon renewal, the following rules apply:

1. 0% Increase: If current rent is up to 10% below the market average.
2. 5% Increase: If current rent is 11% to 20% below the market average.
3. 10% Increase: If current rent is 21% to 30% below the market average.
4. 15% Increase: If current rent is 31% to 40% below the market average.
5. 20% Maximum Cap: If current rent is more than 40% below the market average, the maximum allowable increase is capped at 20%.

90-Day Notice Rule

Even if the RERA index allows for a rent increase:

• The landlord MUST notify the tenant in writing (usually via email or registered letter, not WhatsApp) at least 90 days before the expiration of the current tenancy contract.
• If the landlord fails to give exactly 90 days' notice, or gives late notice, the law stipulates that no rent increase is permitted for the upcoming renewal term. The tenant has the right to renew at the previous year's absolute rate.

Abu Dhabi: The 5% Cap

Abu Dhabi maintains a simpler, stricter cap to combat inflation.

• Annual rent increases in Abu Dhabi are typically capped at a maximum of 5% upon lease renewal.
• Similar to Dubai, Abu Dhabi landlords must provide tenants with at least two months' (60 days) written notice prior to the contract renewal date if they intend to enforce the 5% increase.

If a landlord attempts to increase the rent beyond the 5% cap without a mutual, separate agreement, the tenant can escalate the matter to the Abu Dhabi Rent Dispute Settlement Committee.

Dealing with Tenant Refusals

If a landlord validly issues a rent increase notice within the 90-day (Dubai) or 60-day (Abu Dhabi) window, and the RERA index (or 5% cap) supports the increase, the tenant must either:

1. Accept the increase and sign the renewal.
2. Decline the increase, notify the landlord 90/60 days prior to the end date that they do not wish to renew, and vacate by the expiry of the current contract.

If a tenant refuses to accept a legal increase and refuses to vacate, the landlord can utilize the RDSC to force compliance.
