RERA Rental Index 2026: How to Calculate

Dubai's rental increase regime is not a free-for-all. In 2026, the legal framework still runs through Decree No. 43 of 2013, while the benchmark itself is now shaped by the Smart Rental Index 2025 launched by Dubai Land Department. The operational question is simple: how far below the official comparable rent is your current annual rent? The answer determines whether the maximum legal increase is 0%, 5%, 10%, 15%, or 20%. A second rule matters just as much: unless the parties agreed otherwise, any proposed rent change must be notified at least 90 days before contract expiry.

Featured answer

Under Decree No. 43 of 2013, there is no rent increase if the current rent is up to 10% below the average comparable rent. The maximum increase is 5% if the current rent is 11% - 20% below the benchmark, 10% if 21% - 30% below, 15% if 31% - 40% below, and 20% if more than 40% below. In practice, users now check this through DLD's Rental Index / Smart Rental Index service.

What the RERA Rental Index actually does

The index does two jobs. First, it gives the average rent of similar units in the relevant market segment. Second, it acts as the benchmark for Decree No. 43 of 2013, which caps how much rent can increase on renewal. DLD's current service states that the tool calculates both the rental increase and the average rent in the market by using the contract expiry date, property type, area, rooms, and current annual rent.

Why 2026 is not the same as old rent-index years

On 2 January 2025, Dubai Land Department launched the Smart Rental Index 2025. DLD said the new model uses an advanced building classification system and weighs technical and structural characteristics, quality of finishes and maintenance, location, and service and facility quality including cleanliness, maintenance, and parking management. The practical meaning for landlords and tenants is that the benchmark is no longer just a broad area average in the old sense. Building quality and condition matter more than before.

Decree 43 table: the only increase bands that matter

This table comes directly from the official tenancy guide's reproduction of Decree No. 43 of 2013.

Step-by-step: how to calculate the legal increase

  1. 1

    Check the contract expiry date

    The official DLD tool asks for the contract end date because the inquiry is renewal-focused.

  2. 2

    Open the official DLD Rental Index tool

    Use the DLD website or Dubai REST App rather than a third-party calculator.

  3. 3

    Enter property type, area, room count, and current annual rent

    The benchmark only works if the unit profile is matched correctly.

  4. 4

    Read the average market rent returned by the tool

    This is the benchmark for your comparable-rent calculation.

  5. 5

    Measure how far below the benchmark your current rent is

    Use the Decree 43 table to identify whether the maximum increase is 0%, 5%, 10%, 15%, or 20%.

  6. 6

    Check the 90-day notice rule separately

    Even if the index allows an increase, Article 14 in the tenancy law framework still requires timely notice unless the parties agreed otherwise.

Worked example

The official DLD tenancy guide gives a worked example: if the average rent in the official index is AED 80,000 and the current contract rent is AED 60,000, the rent is 25% below the benchmark. That places it in the 21% - 30% band, allowing a 10% increase. The new rent becomes AED 66,000.

Fees

  • DLD's public Rental Index service is an information/calculation tool. The public service page does not state a user fee for checking the index.
  • The real financial issue is not the lookup cost but the rent increase that may or may not be allowed.

Common mistakes

  • Using asking rents from listing portals instead of the official DLD benchmark.
  • Ignoring the 90-day notice rule and focusing only on the calculator result.
  • Choosing the wrong property type or room count in the official tool.
  • Assuming the Smart Rental Index means landlords can bypass Decree 43. It does not.
  • Treating area-level hearsay as stronger than the official result returned by DLD or Dubai REST.

Need help reading the result?

If the official DLD result and the landlord's position do not line up, a property lawyer or rental-disputes specialist can review the contract timing, the notice trail, and the comparable-rent logic before a dispute escalates. This page is informational only and is not legal advice.

Frequently Asked Questions

No. The increase is still capped by Decree No. 43 of 2013, using the official comparable-rent benchmark.

DLD said the new index classifies buildings using a more detailed, technology-driven model that accounts for building quality, maintenance, location, and services.

Yes. Article 14 in the tenancy-law framework says a party seeking to amend contract terms, including rent, must generally notify the other party at least 90 days before expiry unless otherwise agreed.

The official DLD/RERA benchmark is the starting point. If the parties still disagree, the issue can escalate to the rental-disputes process, where the official benchmark and the facts of the contract matter.
