How the Smart Rental Index Sets the Benchmark
The Smart Rental Index publishes an average rent for every area, building type, and unit configuration in Dubai. It is updated on a rolling basis using actual contract registrations recorded with RERA, which means the figure reflects what tenants are paying in your specific area, not a national average.
You can check the Index for your unit through the DLD or Dubai REST app at any time, and the figure that appears there is what RERA will use if either you or your landlord raises a dispute. Knowing the number before renewal is by far the most useful thing either side can do.
The Five Tiers of Permitted Rent Increase
The framework is simple once you know it. If your current rent is within ten percent of the Index average, no increase is permitted at renewal. If it is eleven to twenty percent below, a five percent increase is allowed. The tiers continue at twenty-one to thirty percent below (ten percent allowed), thirty-one to forty (fifteen percent), and more than forty percent below (twenty percent maximum). This is set in law, not negotiated — and it applies only at renewal, never mid-contract.
Your Rights at Renewal and What to Do
A landlord must give written notice at least 90 days before renewal — anything less is not enforceable.
If your landlord intends to change the rent, they must serve written notice at least ninety days before the contract expires. Verbal warnings, WhatsApp messages, or last-minute notices do not meet the legal threshold. Check the Index for your unit, compare it to your current rent, work out which tier applies, and respond in writing. If your landlord proposes an increase above the permitted tier, you can refuse and cite the Index. Disputes that cannot be settled directly are adjudicated at the Rental Dispute Center, and the Index is the legal benchmark used in those proceedings.
"Cases at the Rental Dispute Center settle in a single hearing when both sides bring the actual Index figure to the table — and drag across months when neither does."

Frequently Asked Questions
How is "market average" calculated?
RERA uses a Smart Rental Index that combines transaction data, recent contract registrations, and area-specific benchmarks. The index is publicly accessible via the DLD/Dubai REST app.
Can my landlord increase my rent in the middle of my contract?
No. Rent changes are only valid at renewal and only with at least 90 days written notice before contract expiry.
What if my landlord wants to raise rent above the permitted tier?
You can refuse and reference the Smart Rental Index. If the landlord escalates, the case goes to RDC. The Index is the legal benchmark.
Does the Index apply to short-term rentals?
No. Short-term holiday rentals fall under a separate DET framework, not RERA tenancy rules.
How accurate is the Index for new buildings?
New buildings sometimes show wider variation because the comparable set is thinner. Disputes in these cases often require formal RDC review.
Can a landlord evict me to bypass the increase rule?
Only for specific legal reasons (sale, personal use, major renovation), with 12 months notice. Eviction to raise rent without a qualifying reason is not permitted.
Conclusion
The framework is straightforward when both sides read it before they need to. The single most useful thing anyone affected by this rule can do is keep a dated copy of the underlying text and refer to it directly — not to paraphrased coverage of it.
