Dubai Rent Increase Rules: RERA Rent Index Explained (2026)

When your tenancy renewal letter lands and the new figure looks high, one question matters most: is this increase even legal? In Dubai, a landlord cannot raise rent freely. The amount is capped by the RERA rent index, a tool published by the Dubai Land Department. This guide explains how the rent index works, what triggers an allowable increase, and the notice your landlord must give you first.

Direct answer. No, your Dubai landlord cannot raise the rent by any amount they like. The legal cap is set by the RERA rent index under Decree No. (43) of 2013. That decree links permitted increases to how far your current rent sits below the average market rent for similar units in your area. Three things decide your outcome:

• The percentage gap between your rent and the area average in the index.
• A valid notice from your landlord at least 90 days before renewal.
• Whether your tenancy contract is registered in Ejari and reflected in the system.

What is the RERA rent index?

The RERA rent index is the official benchmark Dubai uses to decide whether a rent increase is allowed. RERA (the Real Estate Regulatory Agency) is the regulatory arm of the Dubai Land Department. The index compares your current rent against the average rent for similar properties in the same area, building type, and size. If your rent is already close to the market average, no increase is permitted. The bigger the gap below the average, the larger the increase a landlord may apply.

The index is also called the rental index or the rent calculator. You will see all three names used. They point to the same official tool maintained by the Dubai Land Department, and it is the only benchmark a Dubai rental dispute centre will accept as authority.

How the rent index slabs are triggered

The rent index works on slabs, not a flat percentage. Your allowable increase depends entirely on how far below the market average your current rent falls.

Decree No. (43) of 2013 sets out the principle: the closer your rent is to the area average, the smaller the increase a landlord may impose. When your rent sits within a defined band of the average, no increase is allowed at all. As the gap widens into lower bands, a stepped percentage increase becomes permissible, rising to a higher ceiling for the deepest discounts.

The exact percentage bands and their thresholds are set by RERA and the Dubai Land Department, and they can be revised. Rather than rely on a figure that may have changed, confirm the current slab percentages directly through the official rent calculator or with a licensed UAE lawyer. The principle is stable; the numbers are the authority's to set.

The key takeaways are simpler than the bands suggest:

• If your rent already matches the area average, expect no lawful increase.
• The further below the average your rent sits, the higher the permitted step.
• The calculator, not your landlord's opinion, decides the lawful figure.

How to check your rent index with the Dubai REST app

The Dubai REST app is the fastest way to confirm what increase, if any, is lawful for your unit. REST stands for Real Estate Self Transaction, and it is the Dubai Land Department's official mobile service.

Follow these steps before you accept or contest a renewal:

1. Download and register. Install the Dubai REST app and create an account with your Emirates ID and contract details. Allow a short verification period.
2. Open the rental increase calculator. Inside the app, find the rental increase calculator service maintained by RERA.
3. Enter your unit details. Input your area, property type, size, and current annual rent exactly as they appear on your Ejari contract.
4. Read the result. The calculator returns the maximum lawful increase for your unit, expressed as a percentage of your current rent.
5. Save the output. Keep a screenshot. It is your evidence if the landlord demands more than the calculator allows.

The same calculator is available on the Dubai Land Department website. The app and the website draw on the same official index, so the result should match.

When and how your landlord must give notice

A lawful rent increase is not just about the percentage. Timing and notice matter as much as the figure. Your landlord must tell you about any change to the tenancy terms, including a rent increase, well before the contract renews.

Under Dubai's tenancy law, the landlord must serve notice of any proposed change to the rental terms at least 90 days before the contract expiry date, unless you both agree otherwise in writing. If your landlord raises the rent at renewal without giving you that advance notice, the increase can be challenged. The notice should be in writing and clearly state the new figure.

The exact notice period and the form it must take are set by RERA and the Dubai Land Department. Confirm the current requirement with the authority or a licensed UAE lawyer before you act. What does not change is the principle: a surprise increase with no advance written notice is not automatically enforceable.

Common mistakes tenants make with the rent index

Most tenants who overpay do so because they skip a basic check. These are the errors that cost renters money each year.

• Assuming the landlord's number is correct. Landlords sometimes ask for more than the index allows. The calculator is the authority, not the renewal letter.
• Ignoring the 90-day window. If you only react on the expiry date, you may lose the chance to dispute the notice timing.
• Not registering Ejari. An unregistered tenancy weakens your position if you need to file a dispute. Keep your Ejari current.
• Paying under pressure. Agreeing to an unlawful increase to avoid friction sets the new figure as your baseline for the next renewal.
• Confusing area averages. The index compares like with like. A larger or newer building nearby is not your benchmark.

Cost and timeline if you need to dispute an increase

If your landlord insists on an increase the index does not support, the next step is the Rental Disputes Centre, the dedicated tribunal for Dubai tenancy disputes. You file a case, pay the filing fee, and present your evidence, including your REST app calculation and Ejari contract.

Filing fees at the Rental Disputes Centre are typically calculated as a percentage of the annual rent, subject to a cap. The exact rate is set by the Dubai Land Department and can change. Confirm the current fee schedule with the centre or a licensed UAE lawyer before filing. Timelines vary with the complexity of the case and the centre's caseload. A straightforward rent-cap dispute usually moves faster than a contested eviction matter. For the wider picture of how these cases run, see our guide to the Dubai tenancy dispute process at the Rental Disputes Centre.

If you are weighing whether to handle the dispute yourself or get help, you can browse verified real estate and tenancy lawyers in Dubai and message them directly, with no signup required. A lawyer can confirm whether the increase is lawful and represent you if the matter reaches the centre.

When to involve a tenancy lawyer

You can run a simple rent index check yourself in the REST app. Get advice when the situation is no longer simple. That includes a landlord who refuses to follow the calculator, a renewal tied to an eviction threat, or a dispute over whether your unit is correctly classified in the index. A landlord pushing eviction alongside a rent demand is a particular warning sign, because the rules on a 12-month eviction notice in Dubai are separate and strict. If the matter is heading toward a formal filing, our guide to working with a UAE rental dispute lawyer walks through what to expect.

Frequently asked questions

How much can a landlord legally increase rent in Dubai?

Only as much as the RERA rent index allows. Under Decree No. (43) of 2013, the permitted increase depends on how far below the area's average rent your current rent sits. If your rent is close to the average, no increase is allowed. The exact slab percentages are set by RERA and the Dubai Land Department and can change, so confirm the current figure in the official rent calculator before agreeing to any increase.

What is the RERA rent index and where do I find it?

The RERA rent index is the Dubai Land Department's official benchmark for lawful rent increases. It compares your rent against the average for similar units in your area. You can check it through the rental increase calculator in the Dubai REST app or on the Dubai Land Department website. The result tells you the maximum lawful increase for your specific unit.

How does the Dubai REST app calculate my rent increase?

The Dubai REST app uses the official RERA rent index. You enter your area, property type, size, and current annual rent, exactly as shown on your Ejari contract. The calculator returns the maximum lawful percentage increase for your unit. Save a screenshot of the result, because it is your evidence if your landlord demands more than the index permits.

How much notice must my landlord give before raising rent?

Your landlord must give notice of any change to the tenancy terms, including a rent increase, well before the contract renews. The requirement under Dubai tenancy law is at least 90 days before expiry unless you agree otherwise in writing. The exact notice period is set by RERA and the Dubai Land Department, so confirm the current rule with the authority or a licensed UAE lawyer. A surprise increase with no advance written notice can be challenged.

What if my landlord raises rent above the index limit?

You are not obliged to pay an increase the rent index does not support. First, run the calculation in the Dubai REST app and save the result. Then raise it with your landlord in writing. If they refuse to follow the index, you can file a case at the Rental Disputes Centre, presenting your calculation and Ejari contract. A verified tenancy lawyer can confirm your position and represent you if needed.

Does the rent index apply to all of Dubai?

The RERA rent index covers residential and commercial tenancies registered with the Dubai Land Department across Dubai, including free zone communities that fall under DLD oversight. The benchmark adjusts for area, building type, and size, so a downtown apartment and a suburban villa are measured against different averages. Always check your specific unit in the official calculator rather than relying on a neighbour's figure.
