Dubai's rental market continues to evolve rapidly. New residential districts are maturing, thousands of expatriates arrive each month, and rents in many communities have adjusted significantly over the past three years.
In this environment, one mechanism quietly shapes every renewal negotiation: the RERA Rental Index.
In 2025, Dubai's Real Estate Regulatory Agency (RERA), under the Dubai Land Department (DLD), introduced a major upgrade - the Smart Rental Index.
The RERA Rental Index determines whether a landlord can legally increase rent - and by how much - at the time of contract renewal.
Through the DLD website and the Dubai REST app, both tenants and landlords can view:
These calculations are not suggestions - they form the basis of Dubai's rent regulation. If the calculator shows no increase is permitted, the landlord cannot legally raise the rent.
Dubai applies a tiered system to limit rent increases on renewals. The percentage cap depends on how far the current rent is below the RERA-referenced market average:
| Difference from market average | Maximum legal increase |
|---|---|
| 0-10% below average | 0% |
| 11-20% below average | 5% |
| 21-30% below average | 10% |
| 31-40% below average | 15% |
| 40%+ below average | 20% |
If your rent is already aligned with the market, the law prohibits any increase at renewal.
The 2025 upgrade brings several major improvements:
Rental values are now generated using real-time data, including Ejari registrations, market contracts, and building-level characteristics. This results in more accurate benchmarking.
Building-Level Classification
The old index treated every building in a district equally. The Smart Index considers:
This reduces distortions where older towers were compared unfairly with new, premium developments.
More Frequent Updates
The index is now calibrated more often instead of once annually, helping rent caps reflect the market more closely.
Unified Transparency
Both parties see the exact same data. This eliminates guesswork and reduces disputes during renewal negotiations.
Tenants can easily verify their rights by using the Rental Index tool.
Steps:
If the calculator shows 0% allowed, the landlord cannot raise the rent, even if market conditions seem favourable.
Stricter Protection for Rents Already Near Market Value
Because the updated index reflects recent data more accurately, many tenants now fall within the 0-10% band - meaning no legal increase.
Fairer Outcomes in Older Buildings
Older buildings in premium areas no longer inherit the high averages of new developments. This prevents disproportionate increases in aging or poorly maintained towers.
Stronger Dispute Resolution
If a landlord requests an increase above the permissible cap, tenants can rely on:
Although the index governs renewals, it now influences new leases as well.
Soft Pricing Ceiling
New tenants frequently check index values before signing. If a price is far above the benchmark, they can negotiate or choose a more reasonably indexed building.
More Informed Area Comparisons
Renters can compare index values across districts - for example, JVC vs. Dubai Hills vs. Dubai Marina - to anticipate long-term affordability.
Increased Demand in Emerging Communities
As prime districts stabilise at higher levels, relocating tenants often choose emerging areas such as Arjan or Dubai South, attracted by better value and predictable future increases.
The Smart Rental Index is beneficial for investors as well.
Predictable Cash Flow
Rent caps and clearer benchmarks simplify long-term income planning and ROI modelling.
Stronger Tenant Retention
Reasonably priced units renew faster, maintain high occupancy, and reduce turnover costs.
Sustainable Rental Yields
Dubai remains one of the strongest rental markets globally, with yields typically between 5-8%. The updated index supports stable, long-term performance.
More tenants and landlords are agreeing to 2-3-year leases.

For landlords:
Sustainable Rental YieldsPrime Districts (Downtown, Marina, Palm, JBR)
Index values reflect years of strong demand. Renewals are typically stable, with limited upward movement.
Mid-Market Areas (JVC, Business Bay, Al Barsha)
Moderate increases may apply, depending on how current rents compare to the updated averages.
Emerging Communities (Arjan, Dubai South, Meydan)
Still competitively priced, with gradual annual adjustments expected as infrastructure develops. Overall, analysts expect stabilisation rather than sharp increases in 2025.
"My landlord can increase the rent whenever they want."
Incorrect. Increases are allowed only at renewal, based strictly on index rules.
"The index automatically lowers high rents."
It limits increases - it does not reduce existing rents.
"Only apartments are covered."
The index covers apartments, villas, and townhouses.
"The calculator is advisory, not mandatory."
In practice, it is the main reference used in tenancy disputes.

Can my landlord increase rent mid-contract?
No. Increases apply only at renewal and must comply with the index.
How often is the Smart Rental Index updated?
More frequently than before, using ongoing data inputs rather than annual revisions.
Does the index apply to commercial units?
There are separate frameworks for commercial properties; this article focuses on residential.
What if my landlord ignores the allowed cap?
You may reject the increase and, if necessary, file a case with the Rental Dispute Settlement Center.
Are public notices required before renewal changes?
Yes. Landlords must provide 90 days' written notice unless the contract specifies otherwise.
The RERA Smart Rental Index 2025 is reshaping Dubai's rental market by reinforcing structure, data-based benchmarking, and clear legal boundaries. For tenants, it provides protection from excessive increases. For landlords and investors, it creates predictability and supports long-term rental performance.
