Before You Accept a Dubai Rent Increase, Check the Smart Rental Index and the 90-Day Rule

Updated 10 September 2026: the core message of this article survives: before accepting a proposed rent increase in Dubai, check the official Dubai Land Department Rental Index / Smart Rental Index and check whether the required notice was given.

But the old version also described a supposed “2026 update” with new sub-community splits, furnished/unfurnished bands and special studio categories. Robius can find no current DLD source supporting those claims. They have been removed.

What the Smart Rental Index Actually Is

Dubai Land Department launched the Smart Rental Index 2025 on 2 January 2025. DLD says the system uses artificial-intelligence technologies together with an advanced building-classification system to support fairer rental valuations.

The building-classification methodology considers factors such as technical and structural characteristics, quality of finishes and maintenance, strategic location, services, facilities, cleanliness and parking management.

That is the official improvement over relying only on broad area averages. The old Robius article went further and said buildings were rated on a one-to-five-star scale and that 2026 introduced multiple new category bands. Robius could not verify those details from current DLD sources, so they are no longer presented as fact.

The Legal Increase Framework Is Still Decree No. 43 of 2013

The percentage framework comes from Dubai Decree No. 43 of 2013 on determining rent increases for real property.

At renewal, the maximum increase depends on the difference between the current contractual rent and the average rental value of comparable property under the official rent index.

These are maximum permitted increases. They do not require a landlord to raise rent by the full percentage.

Use the Current DLD Result, Not a Screenshot From an Old Article

DLD’s Rental Index service is available through the Department website, Dubai REST, the Ejari system and DubaiNow.

The current service asks for information including the tenancy-contract expiry date, property type, area, number of rooms and current annual rent. The Smart Rental Index dashboard also supports searches using current property information and, where applicable, the Ejari number.

Because the index and building classifications can be updated, the result generated for the actual property and tenancy is more useful than a generic market article.

The 90-Day Notice Rule Is a Separate Check

DLD’s current rental FAQ says that if either party wants to amend contract conditions or reconsider the rental value, they must notify the other party at least 90 days before the contract expires, unless both sides agree otherwise.

That means a tenant checking a proposed increase should ask two different questions:

• What increase, if any, does the current DLD index permit?
• Was the proposed change notified in line with the applicable contract and 90-day rule, or did both parties agree to something different?

The old article stated categorically that any late notice automatically makes an increase illegal in every case. That is too absolute because the parties can agree otherwise and tenancy disputes can turn on the contract and facts. The DLD wording is the safer rule to use.

The Index Applies at Renewal

Decree No. 43 sets its rent-increase percentages for renewing real-property lease contracts. It is not a mechanism for continuously repricing the rent whenever the market changes during the existing agreed lease term.

If a landlord proposes a change during the contract period, check the lease itself and obtain tenancy-law advice where necessary rather than applying the renewal calculator out of context.

The Current Residential Index Does Not Cover Everything

DLD’s current Smart Rental Index FAQ says the index covers residential areas across Dubai, including privately developed areas and free zones, excluding the Dubai International Financial Centre.

DLD’s Smart Rental Index material also says commercial and industrial indices are separate areas of development rather than part of the current residential index.

The old article’s broad statement that commercial property simply follows “its own framework” was directionally safer than applying the residential calculator, but readers should use the current DLD service appropriate to their property type rather than assuming the residential index applies.

DIFC Is an Important Exception

The old article treated the Smart Rental Index as a citywide residential answer without flagging the current DLD FAQ’s DIFC exclusion.

If the property is in DIFC, do not rely on the ordinary DLD Smart Rental Index article as though it automatically decides the permitted increase. Check the DIFC-specific legal and tenancy framework.

The “2026 Update” Section Was Not Verified

The previous Robius version claimed that a 2026 update:

• split large communities into new sub-community and cluster categories;
• introduced separate furnished and unfurnished bands;
• added new studio categories;
• caused index values in popular buildings to move within weeks.

Robius found no DLD announcement supporting that package of changes. The current official material still describes the Smart Rental Index launched in 2025 and its continuous-development approach. Those old claims have been removed rather than recycled.

If the Proposed Increase Does Not Match the Official Result

Keep the current index result, the tenancy contract, renewal notice and written communication with the landlord or property manager.

If the parties cannot resolve the disagreement, Dubai’s Rental Disputes Center is the specialised body for rental disputes. The applicable filing route, fees and legal merits depend on the case, so check the current official RDC / DLD process before filing.

Robius should not tell a tenant to simply refuse payment or ignore a landlord notice based only on an online article. The index is a powerful official reference, but tenancy enforcement is still a legal process.

A Better Two-Minute Check

• Open the current DLD Rental Index / Smart Rental Index.
• Use the actual property and tenancy information requested by DLD.
• Record the permitted increase shown for the relevant renewal.
• Check when the landlord’s proposed change was communicated.
• Compare that against the 90-day rule and any different agreement in the contract.
• If there is still a dispute, preserve the evidence and use the official dispute channel or qualified legal advice.

The Bottom Line

The useful part of the old article was correct: a landlord’s requested number is not automatically the legally permitted number.

The official index and Decree 43 provide the actual framework, and the permitted increase can be zero even in a rising market.

But the best protection is precision, not dramatic wording: check the current index, check the 90-day notice position, check whether the residential DLD framework applies to your property, and do not rely on invented “2026 updates.”
