Dubai’s rental market continues to evolve, but by 2026 it has entered a more regulated and structured phase.
One of the key mechanisms governing lease renewals remains the Dubai Rental Index, administered by Dubai Land Department (DLD) and RERA.
Following the launch of the Smart Rental Index in January 2025, the system became more property-specific by incorporating building classification and additional characteristics that affect rental value.

The Rental Index allows landlords and tenants to determine:
The official calculator is available through the Dubai Land Department Rental Index, including through the DLD website, Ejari system, Dubai REST and DubaiNow.
For residential properties, users can provide information such as:
DLD also allows searches using property- and Ejari-related information in the current version of the service.
For renewal disputes, DLD states that the Rental Index is used to determine the permitted rent increase.
At the same time, DLD clarifies that the index is indicative rather than mandatory when agreeing a completely new lease. It becomes particularly relevant where landlord and tenant disagree over the increase applicable at renewal.

The legal framework for maximum rent increases is established by Decree No. 43 of 2013 Determining Rent Increase for Real Property in the Emirate of Dubai.
The permitted increase depends on how far the existing rent is below the average rental value of comparable property.
| Current rent compared with average rental value | Maximum increase |
|---|---|
| Up to 10% below average | 0% |
| 11–20% below average | 5% |
| 21–30% below average | 10% |
| 31–40% below average | 15% |
| More than 40% below average | 20% |
Article 3 of the Decree states that the average rental value of comparable units is determined according to the Rent Index of the Emirate of Dubai approved by RERA.
Therefore, if the relevant index indicates that the existing rent is no more than 10% below the applicable average, no increase is permitted under the Decree.
Dubai Land Department launched the Smart Rental Index 2025 on 2 January 2025.
The new approach introduced a more detailed building-classification system instead of relying only on broad area-level comparisons.
According to DLD, buildings are evaluated using criteria including:
DLD states that artificial intelligence and building classification are used to support more accurate and transparent rental valuations.
Official source: DLD — Smart Rental Index Announcement.
Dubai Land Department has confirmed that rental-value adjustments under the Smart Rental Index take into account multiple factors, including:
This means that rental assessment is no longer based solely on the name of the wider community.

One of the most significant changes introduced with the Smart Residential Rent Index is the greater role of the individual building.
DLD's official Smart Rental Index guidance explains that classification considers criteria including:
The classification can also be reviewed. DLD states that owners or landlords can submit a request to update a building’s classification.
As a result, two residential buildings in the same neighbourhood do not necessarily need to have identical rental benchmarks if their characteristics differ materially.

The original version of this article described the Smart Index as using “real-time” data and being recalibrated continuously.
A more precise description based on DLD’s official material is that the system is designed to respond more flexibly to market conditions and that the standards and criteria used by the index are continuously updated to keep pace with market changes.
DLD does not state that every property's rental value is recalculated in real time after every new transaction.
Therefore, tenants and landlords should always use the current result generated by the official DLD Rental Index service when preparing for a renewal.
The process is straightforward:
The service is also available through:
DLD describes the service as allowing customers to calculate both the rental increase and average rental value in the real estate market.
The Rental Index is only one part of the rent-increase process.
A landlord who wants to change the rent at renewal must also comply with the applicable notice requirement.
Article 14 of Law No. 33 of 2008 states that, unless the parties agree otherwise, a party wishing to amend the terms of the tenancy contract must notify the other party at least 90 days before the contract expires.
Dubai Land Department also specifically confirms that where a landlord wants to increase the rent, the tenant must be notified at least 90 days before expiry.
DLD's Smart Rental Index guidance further explains that:
Official sources:
A landlord cannot simply choose an arbitrary percentage because rents elsewhere in Dubai have increased.
The permitted increase at renewal must correspond with the applicable Rental Index rules.
The Smart Residential Rent Index considers building characteristics rather than relying solely on broad community averages.
This can create more differentiated rental valuations within the same district.
If landlord and tenant disagree about a proposed increase, they can refer to:
DLD confirms that the Rental Index becomes relevant where contracting parties are in conflict over the permitted increase at renewal.
The legal rent-increase caps primarily address renewals of existing tenancy contracts.
Article 1 of Decree No. 43 of 2013 expressly sets the percentage limits when renewing Real Property Lease Contracts.
For a new tenancy, DLD states that the Rental Index is indicative and is not mandatory in the same way as when resolving a renewal dispute.
This distinction is important.
A prospective tenant can still use the index to understand rental levels in a community, but the statutory 0–20% renewal framework should not automatically be interpreted as a price cap for every newly advertised property.
The Rental Index can also help landlords plan rental income more realistically.
Before proposing a rent increase:
For investors, it is important not to base expected future rental income solely on asking prices for vacant properties.
A tenanted investment may be subject to the existing tenancy contract, Rental Index and statutory increase limits.
Dubai tenancy law allows landlords and tenants to agree contractual terms, including the duration of the tenancy, subject to applicable law.
DLD currently states that an Ejari contract can be registered for a period ranging from less than one year up to a maximum of ten years.

For a multi-year lease, the parties should clearly agree:
The Smart Residential Rent Index launched in 2025 was specifically introduced for residential buildings.
At launch, DLD stated that commercial and industrial indices were under development.
However, DLD's current Rental Index service in 2026 now displays separate categories including:
Therefore, it is no longer accurate to state simply that “the Rental Index does not apply to commercial property”.
The important distinction is that the Smart Residential Rent Index and its building-classification methodology were introduced for the residential segment, while DLD now provides additional rental-index categories through the broader Rental Index service.
Current service: Dubai Land Department — Rental Index.
Incorrect.
A change in rent is normally addressed in connection with renewal, subject to the applicable Rental Index and notice requirements.
Incorrect.
Twenty percent is the maximum tier, applicable where the current rent is more than 40% below the applicable average rental value.
Not necessarily.
For regulated renewal increases, the relevant reference is the DLD/RERA Rental Index rather than asking prices on property portals.
Incorrect.
DLD specifically introduced building-level classification and considers property characteristics, services and other factors.
No.
The rent-increase framework determines whether and by how much rent may be increased at renewal. A reduction is a separate matter between the parties or, where a dispute exists, may be considered by the competent authority.
No.
DLD states that the index is indicative for a new lease and is particularly relevant when parties disagree over an increase at renewal.
Can rent be increased during the tenancy contract?
The rent and other contract terms cannot simply be changed unilaterally during the agreed contractual period.
Changes are generally addressed for renewal in accordance with the tenancy agreement and Dubai rental legislation.
How much can a landlord increase the rent?
The maximum increase depends on the difference between the existing rent and the applicable average rental value:
Does a landlord need to give notice?
Yes.
Unless the tenancy agreement provides otherwise, Article 14 of Law No. 33 of 2008 requires notification at least 90 days before expiry when a party wishes to amend the contract terms.
How does the Smart Rental Index calculate values?
DLD states that the system uses building classification and factors including rental-contract values in the building, average rental values in the area and the building classification.
Building assessment includes characteristics such as quality, maintenance, location and services.
Is the index updated in real time?
DLD states that the index and its standards are designed to adapt to changing market conditions and that the criteria are continuously updated.
It does not describe every rental valuation as being recalculated instantaneously after each individual transaction.
For this reason, users should check the current DLD calculator rather than rely on an older result.
Is the Rental Index mandatory for a new lease?
DLD says no. It is indicative for a new lease.
It becomes particularly relevant where the parties disagree regarding the permitted rent increase when renewing an existing tenancy.
What if the landlord proposes an increase above the permitted amount?
The tenant can refer to:
If the dispute cannot be resolved, the matter can be taken to the Rental Disputes Center.
The Smart Rental Index has made Dubai's residential rent-setting framework more property-specific by combining the existing statutory rent-increase system with a building-classification methodology.
For tenants, the key protections remain straightforward:
For landlords, the same system provides a formal basis for adjusting rents where an existing tenancy is materially below the applicable market benchmark.
The most important point is that market asking prices alone do not determine the lawful increase for an existing tenancy. The DLD/RERA Rental Index and Dubai rental legislation remain the primary references.
