RERA Rental Index Explained: How Dubai Rent Increases Work
Every year, tens of thousands of Dubai tenants receive renewal notices with rent increases. Many accept whatever the landlord demands, not knowing that Dubai has a strict system governing how much rent can legally go up. The RERA Rental Index is your most powerful tool as a tenant, and most people do not know how to use it.
What Is the RERA Rental Index?
The RERA Rental Index is a database maintained by the Dubai Land Department's Real Estate Regulatory Agency that tracks average rental prices across every community in Dubai. It is updated regularly based on actual transaction data from Ejari registrations, giving it a comprehensive picture of what tenants are actually paying.
The index serves two purposes: it provides a benchmark for fair market rent, and it determines the maximum allowable rent increase when your lease comes up for renewal. Landlords cannot legally exceed the increase permitted by the index, regardless of what they claim about market conditions or property improvements.
The Tiered Increase System
The RERA index does not apply a flat percentage cap. Instead, it uses a tiered system based on the gap between your current rent and the average market rent for comparable properties in your area. The system was established by Decree No. 43 of 2013 and works as follows:
Your rent is at or above market rate
Maximum increase: 0% — The landlord cannot raise your rent at all
Your rent is 11-20% below market rate
Maximum increase: 5%
Your rent is 21-30% below market rate
Maximum increase: 10%
Your rent is 31-40% below market rate
Maximum increase: 15%
Your rent is more than 40% below market rate
Maximum increase: 20%
Note that if your rent is up to 10% below market rate, the landlord still cannot increase it. The first tier of increase only kicks in when the gap exceeds 10%.
How to Use the RERA Rent Calculator
The RERA Rent Calculator is available on the Dubai Land Department website and through the Dubai REST mobile app. To use it, you need to enter your property details: the community or area name, the building name, the property type (apartment, villa, studio), the number of bedrooms, and your current annual rent.
The calculator will return the average market rent for comparable properties and tell you the maximum allowable increase. Take a screenshot of this result and save it — it is your evidence if the landlord demands more.
Run the calculator before your lease renewal, not after. If you know the RERA-allowed increase before your landlord sends the renewal notice, you can proactively negotiate from a position of knowledge.
When the Calculator Says Zero: Your Strongest Position
In many areas of Dubai, especially those where rents have increased significantly in recent years, the RERA calculator will show that your current rent is already at or above market rate. In this case, your landlord legally cannot increase your rent at all.
If your landlord still sends a renewal notice with an increase, respond in writing (email is fine) with the RERA calculator result attached. State that under Decree No. 43 of 2013, the increase is not permitted and you intend to renew at the current rate. Most landlords will back down when confronted with the RERA data. If they do not, file at the RDSC.
The 90-Day Notice Requirement
Under Dubai tenancy law, a landlord must provide at least 90 days' notice before the lease expiry date for any change in terms, including rent increases. If your landlord notifies you of an increase with less than 90 days' notice, the increase may not be enforceable for the current renewal period.
The notice must be in writing. A verbal conversation or WhatsApp message may not meet the legal standard, although the RDSC has become more flexible about electronic communication. To be safe, request formal written notice via email or registered mail and respond in the same format.
Common Landlord Tactics and How to Respond
"Market rents have gone up 30%": The RERA calculator uses actual Ejari data, not listings on property portals. Asking prices on Dubizzle are not market rates. Only the RERA index matters.
"I need the unit for personal use": A landlord can request non-renewal for personal use, but must give 12 months notice via notary. They cannot use this as leverage to force an illegal rent increase.
"Accept the increase or leave": You have the legal right to renew at the RERA-allowed rate. If the landlord refuses, file with the RDSC. The court will enforce the RERA index.
How to Challenge an Illegal Rent Increase
If your landlord insists on an increase above the RERA-allowed amount, you have the right to file a case at the Rental Dispute Settlement Centre. The process involves: registering a complaint online or at the RDSC office, paying the filing fee (3.5% of the disputed annual rent, minimum AED 500, maximum AED 20,000), attending a hearing where both parties present their case, and receiving a judgment that is legally binding.
The RDSC consistently rules in favour of tenants when landlords exceed RERA limits. The process typically takes 2-4 weeks for straightforward cases. During the dispute, you can continue occupying the property at your current rent rate — the landlord cannot evict you while the case is pending.
Protecting Yourself at Renewal
Run the RERA calculator 120 days before your lease expiry — know your rights before the landlord contacts you
Screenshot and save the calculator result — this is your primary evidence
Respond to any increase demand in writing, citing the RERA decree number and your calculator result
