Dubai Rent Increase Rules: RERA Rental Index Explained
Few emails make Dubai tenants more nervous than one that starts, "Regarding your upcoming renewal." The good news is that a landlord can't simply pick a new number. Rent increases in Dubai are tied to the RERA rental index, a government benchmark that determines whether rent can rise and by how much.
This guide explains how the RERA rental index works today, the exact increase bands, how to check your own rent with the official calculator, and what to do if a proposed increase doesn't add up. It's written for tenants and landlords alike, because both sides benefit from knowing the rules before the renewal conversation starts.
What Is the RERA Rental Index?
The RERA rental index is the official reference for average rents in Dubai, published by the Dubai Land Department (DLD) through its Real Estate Regulatory Agency (RERA). When you hear people mention the DLD rental index, they mean the same tool.
Its job is simple. It tells you the average market rent for a property like yours, and the law then uses the gap between that average and your current rent to set the maximum increase allowed at renewal.
The rules behind it come from three pieces of legislation:
Law No. 26 of 2007, which regulates landlord and tenant relationships in Dubai
Law No. 33 of 2008, which amended it, including the notice rules
Decree No. 43 of 2013, which sets the rent increase bands
The Smart Rental Index: What Changed in 2025
In January 2025, the DLD replaced the old area-based index with the Smart Rental Index. The older version compared your rent with averages for a broad area, which meant a new tower and a 20-year-old building on the same street could be judged against the same figure.
The smart version is more precise. It looks at:
The classification of the building, based on its quality, services and condition
Actual rental contracts registered in that building
Average rents across the surrounding area
The DLD has said the index updates more frequently than before, so the figure you see in March may differ from the one you saw last year. What didn't change are the increase bands and the notice rules. The law is the same. The benchmark is sharper.
Rent Increase Bands Under Decree No. 43
This is the part most people are looking for. The maximum increase depends on how far your current rent sits below the index average for similar properties.
Your rent compared with the index average
Maximum increase allowed
Up to 10% below
No increase
11% to 20% below
5%
21% to 30% below
10%
31% to 40% below
15%
More than 40% below
20%
If your rent is at or above the average, the landlord can't increase it at renewal.
A worked example
Say you pay AED 80,000 a year and the index shows an average of AED 100,000 for similar units in your building. Your rent is 20% below the average, which falls in the 5% band. The maximum new rent is AED 84,000.
Now take a tenant paying AED 60,000 for a similar unit. That's 40% below the average, so the cap is 15%, taking the rent to a maximum of AED 69,000. Even the largest increase leaves them below market, which is how the bands are meant to work. They let rents catch up gradually rather than in a single jump.
How to Use the RERA Index Rent Calculator
You don't have to guess. The official RERA index rent calculator is free and available on the DLD website and in the Dubai REST app.
Open the Rental Index service on the DLD website or in Dubai REST.
Enter your property details, including the area, building, property type and number of bedrooms.
Enter your current annual rent and your contract end date.
Review the result, which shows the average rent and the maximum permitted increase.
Download the result as a PDF if you may need it in a dispute.
Run the check close to your renewal date, since the index now updates regularly. If you're new to the app, our Dubai REST app guide walks through its main features.
The 90-Day Notice Rule
Even when the index allows an increase, the landlord must give written notice at least 90 days before the tenancy contract expires. The DLD confirmed in 2025 that this requirement still applies under the Smart Rental Index.
If notice arrives late, the landlord generally can't enforce the increase for that renewal. Keep the email or letter, and note the date you received it.
How Often Can Rent Be Increased in Dubai?
Rent can only change at renewal, not partway through a contract. With most Dubai tenancies running for a year, that means a maximum of one increase a year, and only if the index allows it.
The renewed contract must also be registered through Ejari, Dubai's official tenancy registration system. A rent figure that isn't on the registered contract won't hold up if there's a dispute.
What Tenants Can Do if an Increase Seems Unfair
Start with the facts, then talk.
Check the calculator. Download your result and compare it with what the landlord has proposed.
Check the notice date. Was it at least 90 days before expiry?
Speak to the landlord or agent. Many disagreements end here once both sides see the official figure.
File a case if needed. If you can't agree, you can file with the Rental Dispute Settlement Centre (RDSC), which handles tenancy disputes in Dubai. Fees apply, usually a percentage of the annual rent within set limits.
Keep paying rent while the case is open. Stopping payment can weaken your position, even if the increase turns out to be wrong.
What the RERA Rental Index Means for Landlords
For landlords, the index sets the ceiling at renewal, not the price for a new tenant. When a unit is vacant, you can set the rent at market level for the next contract. That's why some owners see a gap between what existing tenants pay and what new tenants in the same building pay.
A few habits help:
Price right from the start. A fair rent on day one keeps you closer to the index average later.
Check the index before sending notice. Ask only for what the law allows.
Weigh the cost of turnover. Replacing a reliable tenant often means vacancy, agency fees and repairs. A smaller increase can work out better than an empty month.
If you're buying to rent, it pays to think about long-term rental demand as much as the purchase price. Our analysis of Dubai rental yields in 2026 shows which areas are performing best.
Thinking About Buying Instead of Renting?
Every renewal is also a reminder that rent goes up while a mortgage payment often stays steadier. For many long-term residents, owning starts to make more sense than renewing year after year.

Common Questions About the RERA Rental Index
Is the RERA rental index the same as the DLD rental index?
Yes. RERA is the regulatory arm of the Dubai Land Department, so both names refer to the same official index.
What is the maximum rent increase in Dubai?
20%, and only when your current rent is more than 40% below the index average for similar properties.
Can my landlord increase rent without 90 days' notice?
No. Written notice must be given at least 90 days before the contract expires, even if the index allows an increase.
Where can I find the RERA index rent calculator?
On the Dubai Land Department website and in the Dubai REST app, under the Rental Index service.
Know the Rules Before Your Renewal
The RERA rental index takes much of the guesswork out of renewals. Check the calculator, confirm the notice date and keep everything in writing, and most rent conversations stay straightforward. For landlords, it means pricing fairly and planning ahead. For tenants, it means knowing exactly where you stand.
