Did your landlord just demand a 25% rent increase? They might be breaking the law. Dubai has strict regulations governing rent increases through the RERA Smart Rental Index – and understanding these rules could save you thousands of dirhams or help you challenge an unfair increase.
This comprehensive guide explains how the RERA rental index works, your rights as a tenant, landlord rights, and exactly how to challenge an illegal rent increase. Whether you are renting or considering the rent vs buy decision, understanding these laws is essential.
What Is the RERA Rental Index?
Official name: Rent Increase Calculator / Smart Rental Index Purpose: Regulates fair rent increases in Dubai Administered by: Real Estate Regulatory Agency (RERA) Legal basis: Decree No. 43 of 2013
How It Works
- Compares your current rent to average market rent for similar properties
- Caps annual increase based on this difference
- Prevents excessive rent hikes
- Protects tenants from exploitation
Who must follow it: All landlords in Dubai (enforceable by law) When it applies: At annual renewal time
What changed with the Smart Rental Index
The Smart Rental Index that took effect in January 2025 changed how the benchmark average is worked out, not the caps. The percentage bands below are still Decree 43 of 2013 and are unchanged. What is new is that the index now benchmarks by building — factoring in a building’s classification and quality rather than treating every unit in an area as equivalent — so two flats of the same size in the same community can sit against different averages.
The practical consequence: the cap is the same as it always was, but the average your rent is compared to may have moved, in either direction, since you last checked. Look your specific unit up on the DLD Dubai REST app or the Smart Rental Index before assuming last year’s benchmark still applies.
RERA Rent Increase Caps Explained
| Current Rent vs Market Rate | Maximum Allowed Increase |
|---|---|
| Up to 10% below market | No increase allowed (0%) |
| 11-20% below market | Up to 5% increase |
| 21-30% below market | Up to 10% increase |
| 31-40% below market | Up to 15% increase |
| Over 40% below market | Up to 20% increase |
Real Examples
Each row is the calculation the Rent Increase Calculator performs, on the same Decree 43/2013 bands.
| Your current rent | Market average for a comparable unit | Gap below the average | Band | Maximum increase | Most you can be charged |
|---|---|---|---|---|---|
| AED 60,000 | AED 65,000 | 7.7% | 10% or less below | 0% | AED 60,000 — no increase |
| AED 60,000 | AED 72,000 | 16.7% | 11%–20% below | 5% | AED 63,000 |
| AED 60,000 | AED 85,000 | 29.4% | 21%–30% below | 10% | AED 66,000 |
| AED 60,000 | AED 110,000 | 45.5% | More than 40% below | 20% | AED 72,000 |
Note how far below the average you have to be before the headline 20% is even available: on AED 60,000 rent, the market average has to exceed AED 100,000. A landlord quoting 20% on a AED 85,000 average is not applying the law — they are applying the wrong base.
Tenant Rights Under Dubai Rental Laws
Security Deposit Protection
- Standard deposit: 5% of annual rent for an unfurnished unit, 10% for a furnished one. The furnished rate is double, and it is the single most common surprise in a Dubai tenancy — on a AED 120,000 furnished lease the deposit is AED 12,000, not AED 6,000
- Return timeline: Within 14 days of move-out (less legitimate damages)
- New builds: Often held in escrow, not by landlord directly
The deposit is a market-standard practice rather than a capped statutory rate, so it is negotiable at signing — but budget for the furnished figure if the unit comes furnished, because that is what will be asked for.
Notice Periods
- Tenant leaving: 90 days notice before lease end
- Landlord not renewing: 90 days notice before lease end
- Landlord selling: 12 months notice required
- Landlord renovating/demolishing: 12 months notice required
Rent Payment Rules
- Typically 1-4 post-dated cheques annually
- Cannot require full year upfront (maximum 4 cheques is standard)
Maintenance Responsibilities
- Landlord: Major repairs (AC, plumbing, structural, appliances that came with unit)
- Tenant: Minor maintenance, consumables (light bulbs, filters)
- Damage: Beyond normal wear and tear is tenant responsibility
How to Challenge an Unfair Rent Increase
Step 1: Check RERA Calculator
- Get official market rate for your property
- Calculate allowed increase based on the table above
- Screenshot or print the result as evidence
Step 2: Negotiate with Landlord
- Show RERA calculator results
- Explain legal caps clearly
- Many landlords are unaware or willing to adjust
- Get any agreement in writing
Step 3: File Complaint If Needed
- Where: Rental Dispute Center (RDC) at Dubai Courts
- How: File online or in person
- Cost: 3.5% of the annual rent, subject to a minimum of AED 500 and a cap of AED 20,000. AED 500 is the floor, not the fee — on AED 100,000 annual rent the case-filing fee is about AED 3,500, and you only reach the AED 20,000 cap above roughly AED 571,000 rent
- Timeline: 2-4 weeks for hearing
- Documents needed: Lease contract, RERA printout, landlord communications
Run the arithmetic before you file. On a AED 100,000 lease, contesting a 5% increase is AED 5,000 at stake against a AED 3,500 filing fee — worth it only if the case is clear-cut. On a AED 300,000 lease the same 5% is AED 15,000 against a AED 10,500 fee. The fee scales with the rent, so it does not automatically get more worthwhile as the stakes rise.
Success rates: High if clearly violating RERA caps. RDC typically rules in favor of legal increase limits.
EJARI Registration: What Tenants Must Know
What is EJARI: Official registration of tenancy contracts with Dubai Land Department
- Purpose: Protects both tenant and landlord rights
- Who registers: Usually landlord or agent
- Cost: AED 215 + 5% admin fee = ~AED 225
Why EJARI Matters for Tenants
- Required for DEWA connection
- Needed for visa applications/renewals
- Proof of residence for bank accounts, schools
- Enforceable in disputes – unregistered contracts are harder to enforce
Key Takeaways
- Rent increases are capped: 0-20% maximum depending on how far below market you are
- Check RERA calculator: Official tool determines your allowed increase
- 90 days notice required: For any rent increase or non-renewal
- 12 months for eviction: If landlord wants to sell or renovate
- Deposits are 5% unfurnished, 10% furnished: And must be returned within 14 days
- Filing a dispute is not AED 500: The RDC fee is 3.5% of annual rent (min AED 500, capped AED 20,000)
- EJARI is essential: Insist on registration for your protection
- You can challenge: Rental Dispute Center handles violations
Conclusion: Know Your Rights
Dubai rental laws offer strong tenant protections – but only if you know and exercise your rights. Check the RERA calculator before accepting any increase, and do not hesitate to challenge illegal demands through proper channels.

Frequently Asked Questions
Can my landlord increase rent by more than 20%?
No. The maximum allowed increase under Dubai law is 20%, and only if your current rent is more than 40% below market rate. Most tenants qualify for much lower increases or none at all. Check the RERA calculator to confirm your specific situation.
What if my landlord wants to sell the property?
They must give you 12 months written notice through notary public. You cannot be evicted mid-lease for this reason. The new owner inherits your lease terms until it expires.
Can I negotiate rent even if the increase is legal?
Absolutely. The RERA caps are maximums, not requirements. You can always negotiate for a lower increase, especially if you are a reliable long-term tenant. Landlords often prefer keeping good tenants over maximizing short-term rent.
What happens if I do not have EJARI registration?
You may face difficulties connecting DEWA, renewing your visa, or enforcing your rights in disputes. Always insist on EJARI registration within 30 days of signing your lease.
