RERA Rent Increase Calculator 2026: How to Check If Your Landlord's Increase Is Legal
REC Community Manager
TL;DR — What You Need to Know
- Dubai landlords can only increase rent according to the RERA Smart Rental Index — not by any amount they choose.
- The maximum increase depends on how far your current rent sits below the average market rent for comparable properties.
- If your rent is within 10% of market average, your landlord cannot raise it at all.
- You must receive 90 days' written notice before any increase takes effect.
- If the proposed increase exceeds the legal cap, you can dispute it at the Rental Disputes Centre (RDC).
Every year, thousands of tenants in Dubai receive rent increase notices from their landlords. Some are reasonable. Others feel arbitrary — a sudden 15% or 20% jump that catches you off guard just as your lease renewal approaches.
Here is the good news: Dubai has one of the most transparent rent regulation systems in the region. Decree No. 43 of 2013, issued by His Highness Sheikh Mohammed bin Rashid Al Maktoum, established a clear framework that ties allowable rent increases to market data — not landlord discretion.
This guide walks you through exactly how the system works, how to use the official RERA calculator to verify your landlord's proposed increase, and what steps to take if the increase is not legal. Whether you are a first-time renter or a long-term resident, understanding these rules can save you thousands of dirhams every year.
How the RERA Rent Increase System Works
The foundation of Dubai's rent regulation is Decree No. 43 of 2013, which replaced the earlier Decree No. 2 of 2011. This decree established a percentage-based cap system that determines how much a landlord can increase your rent upon renewal.
The core principle is straightforward: rent increases are tied to how your current rent compares to the average market rent for similar properties in your area. The Dubai Land Department (DLD) maintains the Smart Rental Index, which calculates this average based on actual transaction data from Ejari registrations across the emirate.
The system works on a sliding scale. If your current rent is close to what the market considers fair, the landlord has limited or zero ability to increase. If your rent is significantly below market rate — perhaps because you signed your contract years ago when prices were lower — the landlord can increase by a higher percentage, but still within defined caps.
This means two tenants in the same building could face different allowable increases depending on what they currently pay. A tenant paying AED 60,000 for a one-bedroom in Dubai Marina where the market average is AED 85,000 would face a different cap than a neighbour paying AED 78,000 for an identical unit.
Importantly, the decree applies to all residential and commercial tenancies governed by RERA. It applies at the point of lease renewal — not during the middle of an active lease. A landlord cannot increase your rent mid-contract unless your contract explicitly allows for it (which is extremely rare and generally unenforceable).
The RERA Rental Index Percentage Bands
The percentage bands are the heart of the system. They determine the maximum allowable increase based on the gap between your current rent and the market average.
| Your Rent vs. Market Average | Maximum Allowed Increase |
|---|---|
| Within 10% of market average (at or above) | 0% — No increase allowed |
| 11% to 20% below market average | 5% |
| 21% to 30% below market average | 10% |
| 31% to 40% below market average | 15% |
| More than 40% below market average | 20% |
Key point: these are maximum caps. A landlord can always increase by less than the allowed percentage — or not increase at all. But they can never legally exceed the band that applies to your situation.
Also note that the percentage applies to your current annual rent, not to the market average. So if you pay AED 70,000 and the maximum allowed increase is 10%, the new rent cannot exceed AED 77,000 — regardless of what the market average says the unit should rent for.
Step-by-Step: How to Use the Smart Rental Index
Dubai offers multiple ways to check the rental index. Here is how to use each one.
Option 1: DLD Website (Official RERA Rental Index Calculator)
- Visit the Dubai Land Department website at dubailand.gov.ae.
- Navigate to the "Rental Increase Calculator" tool under the Services section.
- Select the property type (apartment, villa, studio, office, etc.).
- Choose the area where your property is located (e.g., Dubai Marina, JLT, Business Bay).
- Select the sub-community or building name if available.
- Enter the number of bedrooms.
- Enter your current annual rent in AED.
- Click "Calculate" to see the result.
The tool will display the average market rent for your property type in that area and tell you the maximum permissible increase percentage. It will also show the maximum new rent amount in AED.
Option 2: Dubai REST App
The Dubai REST mobile app (available on iOS and Android) is the DLD's official app that includes the rental index calculator along with other property services. The process is identical to the website — select your property details, enter your rent, and the app returns the maximum allowed increase.
The app has the advantage of being accessible anywhere and stores your previous searches, which is useful if you are comparing multiple properties or tracking changes over time. For a full walkthrough of the app, see our Smart Rental Index step-by-step guide.
Option 3: Cross-Reference with Market Data
While the DLD calculator is the official and legally binding tool, you can also cross-reference its results with current listings on platforms like Dubizzle (now Bayut/Dubizzle) and Property Finder. Search for properties matching your unit's specifications in your building or community to see what the current asking rents are. This gives you additional context — though remember that asking prices are often higher than actual transaction prices recorded in the rental index.
What Information You Need
Before you use the calculator, gather the following:
- Your Ejari registration number — this confirms your current lease details. If you are not sure about your Ejari status, read our Ejari registration guide.
- Your current annual rent — the total amount stated in your tenancy contract (not the per-cheque amount).
- Property type — apartment, villa, studio, townhouse, etc.
- Number of bedrooms.
- Building name or community — be specific, as rental averages vary significantly between buildings in the same area.
- Area/sub-area — e.g., "JLT Cluster D" rather than just "JLT".
Having your actual tenancy contract on hand is also useful, as it will show your exact lease start date, renewal terms, and any clauses about rent review.
When Can Your Landlord Increase Rent?
Dubai rental law imposes strict timing requirements on rent increases. Understanding these rules is critical because an increase that violates the timing rules is void — even if the percentage itself is within RERA limits.
The 90-Day Notice Rule
Under Article 14 of Law No. 26 of 2007 (as amended by Law No. 33 of 2008), a landlord must provide the tenant with at least 90 days' written notice before the lease expiry date if they intend to increase the rent. If they fail to give notice within this timeframe, the lease renews at the same rent for another year.
This notice must be delivered in writing — a verbal conversation or WhatsApp message does not constitute legal notice. The standard practice is a notarized letter sent via registered mail or hand-delivered with a signed acknowledgment. Some landlords use notary public services or court notifiers for formal delivery.
Minimum 12-Month Gap
There must be at least 12 months between rent increases. This means if your landlord increased your rent at the last renewal, they cannot increase it again at the next renewal unless a full year has passed. This effectively limits increases to once per annual renewal cycle.
Mid-Contract Increases
A landlord cannot increase rent during an active lease term. If your contract runs from January 2026 to December 2026, the rent is fixed for that entire period. Any clause in a contract that allows mid-term increases is generally considered unenforceable by the Rental Disputes Centre.

What to Do If Your Landlord's Increase Exceeds RERA Limits
If you have checked the RERA calculator and your landlord's proposed increase exceeds the legally allowed maximum, here is what to do — step by step.
Step 1: Verify Your Calculation
Double-check your inputs in the RERA calculator. Make sure you are using the correct area, building, property type, and number of bedrooms. Small errors in these fields can change the result. Take a screenshot of the calculator result showing the maximum allowed increase.
Step 2: Communicate with Your Landlord
Many landlords are not aware of the exact RERA limits or may have relied on their property management company's recommendation. Send a polite but clear message — in writing — sharing the RERA calculator result and asking them to revise the increase to the legal maximum.
Our guide on how to negotiate rent in Dubai includes specific scripts and strategies you can use in this conversation.
Step 3: File a Complaint with RERA
If the landlord does not agree to adjust the increase, you can file a complaint with RERA's Rental Dispute Settlement Committee. This is a free initial step that attempts to mediate between landlord and tenant.
Step 4: File a Case at the Rental Disputes Centre (RDC)
If mediation fails, you can formally file a case at the Rental Disputes Centre, which operates under the Dubai Land Department. Here is what you need:
- Copy of your tenancy contract
- Copy of your Ejari registration
- The landlord's rent increase notice
- Screenshot of the RERA calculator showing the legal maximum
- Any correspondence with the landlord about the increase
- Payment of the filing fee (3.5% of the annual rent, minimum AED 500, maximum AED 20,000)
The RDC typically resolves cases within 15 to 30 working days. Their decisions are binding and enforceable. In the vast majority of cases where the increase clearly exceeds RERA limits, the ruling favours the tenant.

Common Mistakes Tenants Make
Understanding the rules is one thing. Applying them correctly is another. Here are the most frequent errors tenants make when dealing with rent increases.
1. Not Checking the RERA Index at All
Many tenants simply accept whatever increase the landlord proposes without checking whether it is legal. The RERA calculator takes less than two minutes to use. Always check before responding to a rent increase notice.
2. Confusing Asking Rent with Market Average
Tenants sometimes check listings on Dubizzle and see higher prices, then assume their landlord's increase is justified. The RERA index is based on actual transaction data (Ejari registrations), not asking prices. Listings are often 10–20% higher than what tenants actually pay.
3. Not Responding Within the Timeframe
If you receive a rent increase notice and do not respond, the landlord may assume you have accepted it. Always respond in writing — even if you agree to the increase — to maintain a clear record.
4. Assuming the Increase Percentage Is Based on Market Rent
The percentage cap applies to your current rent, not the market average. If the calculator says a 10% increase is allowed and you pay AED 80,000, the maximum new rent is AED 88,000 — not 10% of the market average.
5. Ignoring the 90-Day Notice Requirement
If your landlord sends the increase notice less than 90 days before your lease expires, the notice is legally invalid. You have the right to renew at the same rent. Many tenants do not know this rule and accept late notices.
6. Agreeing to an Illegal Increase to Avoid Moving Costs
Some tenants accept an above-limit increase because moving is expensive and disruptive. While understandable, this sets a higher base rent that future increases will be calculated from — costing you more in the long run. If the increase is illegal, challenge it. You may also want to understand the early termination rules in case you are considering other options.
Landlord's Perspective: How to Propose a Legal Increase
If you are a landlord, following the legal process protects you from disputes and potential RDC cases. Here is how to handle a rent increase correctly.
Check the Rental Index First
Before sending any notice, check the RERA calculator yourself. Enter your property details and the tenant's current rent to see what increase — if any — you are entitled to. This prevents uncomfortable situations where you propose an increase the tenant can easily disprove.
Send a Proper Notice
Your notice must meet three criteria:
- Written — typed or printed, not verbal.
- Delivered at least 90 days before lease expiry — count calendar days carefully.
- Delivered via a verifiable method — registered mail, notary public, or hand delivery with signed acknowledgment. Email is acceptable if your tenancy contract specifically recognises email as a valid communication channel.
Be Transparent About the Calculation
Include a reference to the RERA calculator result in your notice. This demonstrates good faith and reduces the likelihood of a dispute. Tenants are more likely to accept an increase they can verify is within legal limits.
Consider Market Conditions
Just because the RERA calculator allows a 10% increase does not mean you should apply the full amount. Good tenants who pay on time and maintain the property have value. A smaller increase that retains a reliable tenant is often more profitable than the maximum increase that drives them to negotiate aggressively or vacate.
Real Examples: Calculating Your Maximum Allowed Increase
Let us walk through three realistic scenarios to show how the RERA bands work in practice.
Scenario 1: One-Bedroom in JLT — No Increase Allowed
| Detail | Amount |
|---|---|
| Current annual rent | AED 72,000 |
| RERA market average for similar unit | AED 75,000 |
| Difference | AED 3,000 (4% below market) |
| RERA band | Within 10% of market average |
| Maximum allowed increase | 0% — AED 72,000 (no increase) |
Result: Ahmed's landlord sent a notice requesting a 5% increase to AED 75,600. This is illegal. Ahmed's rent is only 4% below the market average, which falls within the 0% band. He should reply with the RERA calculator result and politely decline the increase.
Scenario 2: Two-Bedroom in Business Bay — 10% Increase Allowed
| Detail | Amount |
|---|---|
| Current annual rent | AED 85,000 |
| RERA market average for similar unit | AED 115,000 |
| Difference | AED 30,000 (26% below market) |
| RERA band | 21–30% below market average |
| Maximum allowed increase | 10% — up to AED 93,500 |
Result: Sara's landlord proposed an increase to AED 100,000 (a 17.6% increase). This exceeds the allowed 10% cap. Sara can accept a maximum increase to AED 93,500 and should send the RERA calculator screenshot to her landlord. If the landlord insists on AED 100,000, Sara can file with the RDC — and she will win.
Scenario 3: Three-Bedroom Villa in Arabian Ranches — 20% Increase Allowed
| Detail | Amount |
|---|---|
| Current annual rent | AED 120,000 |
| RERA market average for similar unit | AED 210,000 |
| Difference | AED 90,000 (43% below market) |
| RERA band | More than 40% below market average |
| Maximum allowed increase | 20% — up to AED 144,000 |
Result: The Khans signed their villa lease three years ago at AED 120,000 when the market was softer. The market has since risen sharply, and their rent is now 43% below average. The landlord is legally entitled to the maximum 20% increase, bringing the rent to AED 144,000. While this is a significant jump, it is within legal limits. Even after the increase, the Khans will still be paying well below the market rate — and next year, the landlord could apply another increase depending on where the new rent sits relative to the updated market average.
These scenarios illustrate a critical point: the RERA system protects tenants from sudden jumps to full market rate. Even when a tenant's rent is dramatically below market, the increase is capped at 20% per year — giving tenants time to adjust or plan a move if needed.
Frequently Asked Questions
Does the RERA rental index apply to all properties in Dubai?
The RERA rental index applies to all residential and commercial properties in areas regulated by RERA (Real Estate Regulatory Agency) within the Dubai Land Department. This covers the vast majority of rental properties in Dubai, including apartments, villas, offices, and retail spaces. Properties in free zones with their own rental regulations may have different rules — always check with the relevant free zone authority.
Can my landlord increase rent by more than 20%?
No. Under Decree No. 43 of 2013, the absolute maximum rent increase is 20%, and that only applies when your current rent is more than 40% below the market average. There is no legal mechanism for a landlord to increase rent beyond 20% in a single renewal period. If your landlord is demanding more, they are violating the law.
What happens if I do not have an Ejari registration?
Without an Ejari registration, your tenancy contract is not officially recognised by the DLD. This weakens your legal position in any dispute. If your contract is not registered, prioritise getting it registered immediately. Some landlords avoid Ejari to keep rents off the official index — this is itself a violation. You can register your Ejari yourself through the DLD website or Dubai REST app.
Can my landlord refuse to renew the lease instead of increasing rent?
A landlord can refuse to renew your lease, but only under specific conditions outlined in Dubai rental law — such as wanting to sell the property, use it personally, or demolish/renovate it. They must provide 12 months' notice via notary public. A landlord cannot refuse renewal solely because you refused an illegal rent increase. If they try this, file a complaint with the RDC immediately.
Is the RERA calculator result legally binding?
Yes. The RERA rental index calculator is the official tool used by the Rental Disputes Centre to determine whether a rent increase is within legal limits. If you file a dispute, the RDC will use the same index to make its ruling. This is why taking a screenshot of your calculator result is valuable evidence.
How often is the RERA rental index updated?
The Smart Rental Index is updated regularly based on actual Ejari transaction data. The DLD does not publish a fixed update schedule, but the index generally reflects rental transactions from recent months. This means the market average can change between the time you check it and the time your lease actually renews — always check close to your renewal date for the most accurate result.
Can I negotiate a lower increase even if the RERA calculator allows a higher one?
Absolutely. The RERA percentage bands set the maximum allowed increase — not a mandatory one. Many landlords are willing to negotiate a lower increase to retain good tenants. Factors like your payment history, property condition, vacancy rates in the building, and market trends all give you leverage. See our guide on negotiating rent in Dubai for specific tactics.
What is the filing fee for an RDC dispute?
The Rental Disputes Centre charges a filing fee of 3.5% of the annual rent, with a minimum of AED 500 and a maximum of AED 20,000. This fee is paid upfront when you file your case. If you win, you can request that the losing party bear the filing costs — though the RDC has discretion on this. Given that challenging an illegal rent increase often saves tenants thousands of dirhams, the filing fee is usually a worthwhile investment.
