Dubai rent cap and rent increase rules: the 2026 guide to the RERA index, permitted increases and notice periods

Dubai landlords cannot simply choose any rent increase they want at renewal. In 2026, an increase needs to be supported by the Dubai Land Department rental index and the tenant normally needs to receive notice at least 90 days before the tenancy contract expires if the landlord wants to change the rent or another contract term.

The maximum increase can range from 0% to 20% depending on how far the existing rent sits below the average rental value determined by the official index. The index was upgraded through the Smart Rental Index, which uses building-level classification and market data to produce a more specific rental benchmark.

For landlords, the key is to check the official result before issuing a renewal proposal. For tenants, the key is to check both the permitted percentage and whether the required notice was given on time.
 

What is the Dubai rent cap?

Dubai's rent cap is the framework that limits the percentage by which rent can increase when an existing tenancy is renewed. It is designed to connect permitted increases with the gap between the tenant's current rent and the rental value of comparable property rather than allowing an unrestricted increase.

The underlying percentages are set out in Decree No. 43 of 2013, while Dubai Land Department provides the official Rental Index service used to calculate the relevant rental benchmark and potential increase.
 

How much can a landlord increase rent in Dubai in 2026?

The permitted increase depends on how far the current rent is below the average rental value of comparable property. If the current rent is up to 10% below the average, there is no permitted increase under the decree. If it is 11% to 20% below, the maximum increase is 5%. If it is 21% to 30% below, the maximum is 10%. If it is 31% to 40% below, the maximum is 15%. If it is more than 40% below, the maximum is 20%.

The percentage applies to the existing rent, not directly to the market average. For example, if a tenant currently pays AED 100,000 and the official result permits a 10% increase, the maximum renewal rent under that calculation would be AED 110,000.

A market listing showing a similar property at AED 140,000 does not by itself allow the landlord to raise the tenant's rent to that figure. Check the official DLD result for the tenancy.
 

What is the Smart Rental Index?

Dubai Land Department launched the Smart Rental Index in 2025 to make rental valuation more property-specific. DLD explains that the index uses an advanced building classification system that considers technical and structural characteristics, finishes, maintenance, location, services and facilities, supported by artificial intelligence and current market data.

That is an important shift from thinking about rent as one broad figure for an entire neighbourhood. Two buildings in the same area can offer very different quality, maintenance and facilities, so the index is designed to reflect those differences more accurately.
 

How do you check the permitted rent increase?

Use the official Dubai Land Department Rental Index through the DLD website or supported government apps. The DLD service asks for details including the tenancy expiry date, property type, area, number of rooms and current annual rent before displaying the relevant result.

Check the result close enough to renewal to make it useful, while still leaving time to meet the notice requirement. Landlords should keep a record of the result used when communicating a proposed increase. Tenants should run the same check if the proposed amount appears higher than expected.
 

How much notice must a landlord give for a rent increase?

Under Law No. 33 of 2008, where either party wants to amend the tenancy terms at renewal, they must notify the other party at least 90 days before the lease expires unless the contract provides otherwise. A rent increase is a change to the tenancy terms, so the 90-day timing is critical.

Dubai Land Department has also confirmed how the notice rule works with the Smart Rental Index: if the landlord did not provide the required notice at least 90 days before expiry, an increase supported by the index is not applied for that renewal.

This means an eligible increase and valid notice are separate requirements. A landlord can have an index result that supports an increase but still lose the ability to apply it at that renewal if notice is late.
 

Can a landlord increase rent every year in Dubai?

A landlord can review the rent at renewal, but an increase is not automatic every year. The official index must support an increase and the required notice must be given. If the current rent sits within the no-increase band, the landlord cannot simply add a percentage because another year has passed.

Likewise, the maximum is determined by the applicable band. If the result permits 5%, the landlord cannot impose 10% simply because market asking rents have risen faster. The permitted cap is the maximum under the regulated calculation.

Landlords should therefore treat each renewal as a fresh check rather than assuming last year's percentage carries forward.
 

Is a rent increase notice the same as an eviction notice?

No. The 90-day notice for amending renewal terms is different from the notice required when a landlord seeks eviction on certain grounds after the tenancy expires.

Dubai's tenancy law provides specific post-expiry eviction grounds, including where the owner intends to sell the property or needs it for their own use subject to the legal conditions. For those grounds, the law requires at least 12 months' notice and specifies how that notice must be served.

Do not treat a 90-day rent increase email as a substitute for a legally compliant eviction notice, or vice versa. They deal with different actions and different notice periods.
 

What should landlords do before proposing an increase?

Start with the tenancy expiry date. Work backwards by more than 90 days so there is time to check the official index, consider the condition of the property, review the tenant's history and decide whether you actually want to change the rent.

Then run the DLD calculation and make the proposed renewal clear in writing. If the index does not support an increase, plan the renewal on that basis rather than using asking rents from new listings as a replacement calculation.

A good landlord strategy is not simply to push rent to the maximum every year. Consider the value of a reliable tenant, potential vacancy, reletting costs, maintenance and the wider return from the property. Our Landlord's Guide covers the broader practical responsibilities of renting out a Dubai property.
 

What should tenants do when they receive a rent increase?

Check three things: the expiry date, the date the increase was communicated and the official DLD Rental Index result. If the proposed amount matches the permitted percentage and the notice was given correctly, you can assess whether you want to renew or move.

If the proposed amount appears higher than the official cap, respond with the relevant result and ask the landlord or agent to review it. If the notice arrived late, raise that point clearly. Keep the discussion factual and written.
