Ever found yourself scratching your head, wondering how your Dubai landlord decides whether they can raise your rent when it’s time to renew? It all boils down to something called the RERA Rental Index. Think of it as the Dubai Land Department’s official yardstick for what counts as the average rent for your home.
And just so you know, the rules about how much your rent can go up come from Decree 43 of 2013, not from what you see on property websites or what agents might tell you.
In this guide, I’ll walk you through what the rera rental index actually is, how you can check it for yourself (yep, it’s easier than you think), what those legal brackets really mean, how to figure out if your rent might go up, and what’s changed with the new Smart Rental Index.
No need to slog through a giant renting-in-Dubai manual. I’ll keep things simple and to the point here.

What Is the RERA Rental Index?
So, what’s the deal with the RERA Rental Index? It’s basically Dubai’s official rent guide, put together by the Real Estate Regulatory Agency (RERA) under the Dubai Land Department. Decree 43 is the rulebook that decides what counts as the average rent for homes like yours.
If your landlord wants to increase your rent when it’s time to renew, they must use this rera rental index as their reference. No shortcuts allowed. Here’s the short version: the rera rental index is Dubai’s go-to guide for what a typical place like yours should actually rent for.
Your current rent gets compared to that average, and how far below it you are decides how much your landlord can legally add when it’s time to renew. It’s not a price tag for new leases, it’s more like the official measuring stick for renewals.
Since 2 January 2025, the DLD has been using the Smart Rental Index 2025. This new system looks at things like the building’s structure, how well it’s maintained, where it’s located, and even services like cleaning and parking.
The Decree 43 percentage bands haven’t changed, but the benchmark they use is now more tailored to each building.
Where Do You Check the Official Rental Index?
You can check the latest RERA Rental Index yourself, no need to rely on anyone else. Just go to the Dubai Land Department website, open the Dubai REST app, use the Ejari section on the DLD site, or try DubaiNow. The best part? You get your answer instantly.
What the official service asks for (published procedure):
- Tenancy contract expiry/end date
- Property type (e.g. residential)
- Area/region (and, where the form supports it, building-level identifiers)
- Number of rooms/bedrooms
- Your current annual rent (not the landlord’s proposed new rent)
Some forms also let you enter a DEWA premises number or your Ejari contract number to pull up your property details. Whatever number the tool gives you, keep it hand. It’s your proof for negotiations or if you ever need to take things to the Rental Dispute Centre.
Stick with the official DLD or Dubai REST results instead of third-party calculators, they can be out of date or might not match your building correctly.
Take a screenshot or save a PDF of your result (with the date you checked). If you need to register your tenancy, check out Ejari Registration for that side of things.
What Is the Decree 43 Rent-Increase Brackets?
Under Decree No. (43) of 2013, when a real-property lease is renewed, the maximum increase depends on how far the current rent sits below the average rental value of similar units on the rera rental index.
| Up to 10% below | 0% (no increase) |
| 11%–20% below | 5% of current rent |
| 21%–30% below | 10% of current rent |
| 31%–40% below | 15% of current rent |
| More than 40% below | 20% of current rent (cap) |
Remember, these percentages are just the maximum allowed—they’re not automatic. You and your landlord can always agree on a smaller increase, or even none at all. Decree 43 covers landlords all across Dubai, including special development zones and free zones like DIFC.
Note on official wording: English translations of the Decree use “up to ten per cent (10%) less” for the zero band, then jump to “eleven per cent (11%) to twenty per cent (20%).”
Use whatever band the live calculator gives you, instead of arguing the details yourself. If there’s ever a conflict between versions, the Arabic text is what counts.
Does Decree 43 Apply to New Contracts or Only Renewals?
Decree 43’s rules on rent increases only apply when you renew your lease. If you’re signing a brand-new contract as a new tenant, there’s no legal cap on the starting rent.
When you’re renting a place for the first time, you and the landlord can usually negotiate the starting rent however you want, as long as you stick to the contract and the law.
The RERA rental index is still super handy—it helps you see whether the asking rent is fair compared to the average, so you can decide whether to accept, negotiate, or keep looking.
Once you’re settled in and it’s time to renew, that’s when Decree 43 and the 90-day notice rules kick in for any rent changes.

How Do You Calculate a Proposed Rent Increase?
Here’s how to work it out: subtract your current annual rent from the rera rental index average, turn that gap into a percentage of the average, match it to the right Decree 43 band, and then apply that percentage to your current rent. Or, just let the official calculator do the math for you.
Worked example (illustrative numbers only — always run your own unit on DLD / Dubai REST):
· Current annual rent: AED 80,000
· Index average for similar unit: AED 100,000
· Gap below average: AED 20,000 → 20% below average
· Decree band: 11%–20% below → maximum increase 5%
· Maximum new annual rent: AED 80,000 × 1.05 = AED 84,000
If the same AED 80,000 sat only 8% below an AED 87,000 average, the band would be “up to 10% below” → 0% increase.
Before you say yes to your landlord’s new number, here’s a quick checklist:
Run the official RERA Rental Index for your expiry date, property type, area/building, bedrooms, and current annual rent.
Confirm the notice was given on time (see next section).
Check that the proposed percentage does not exceed the calculator / Decree band.
Make sure the new rent and cheque schedule are sorted on your renewed Unified Tenancy Contract before you re-register Ejari. For more on that, check out /dubai-rental-cheques/.
What Notice Must a Landlord Give for a Rent Increase?
Unless the lease says otherwise, the party who wants to amend terms at renewal, including rent, must notify the other in writing at least 90 days before the contract expires. That rule comes from Law No. (26) of 2007 as amended by Law No. (33) of 2008 (Articles 13 and 14).
“Notice” under the amended law means a written notification sent through a Notary Public, by registered mail, by hand, or by any other technological means approved by law.
If your landlord suddenly sends a WhatsApp asking for a 20% increase without proper notice or index support, that’s not legally binding.
If neither side gives proper notice in time, your renewal usually rolls over on the same terms for the same period or one year, whichever is shorter (as long as you follow the law’s renewal rules). For more on your rights, maintenance, eviction, or deposits, check out /dubai-tenant-rights/.
What Changed with the Smart Rental Index (2025–2026)?
DLD rolled out the Smart RERA Rental Index 2025 on 2 January 2025. It uses artificial intelligence and a building classification system, so two buildings in the same area can have different benchmark rents if factors like quality, finishes, location, or services differ.
What hasn’t changed: the Decree 43 percentage ladder (0 / 5 / 10 / 15 / 20%). For many tenants, the “average” rent may now be higher or lower than before, since it’s no longer based only on the area. That can move your unit into a different increase band.
DLD’s launch materials also note plans to expand coverage toward commercial and industrial indexes over time; as of this draft’s verification, treat commercial/industrial coverage as evolving and confirm on the live DLD service for your property type.
Here’s the practical takeaway for 2026 renewals: always check the live official tool close to your notice window. Don’t rely on last year’s screenshot or a broker’s spreadsheet—they might be out of date.
What If You Dispute a Rent Increase (RDC Angle)?
If the landlord and tenant cannot agree on a fair renewal rent after proper process, Dubai’s tenancy framework lets you take the dispute to the Rental Disputes Settlement Centre (RDC) under DLD, and Law 33 points the tribunal to criteria that include RERA’s rent-increase rules and similar-property rental values.
Before filing anything:
Hang on to the official rera rental index result and your landlord’s written notice (make sure you have proof of when it was delivered).
Double-check that your Ejari is up to date for your current contract—unregistered leases are much harder to fight for.
Compare your landlord’s proposed rent with the Decree band. If they’re asking for more than the cap, let them know in writing and attach the calculator result.
Try making a documented counteroffer (this often works—see /negotiate-dubai-rent/ for tips).
RDC procedure, fees, and timelines change; treat this section as orientation and confirm current filing steps on RDC / DLD channels before you pay or submit.
RERA Rental Index Checklist (Renewal Season)
Mark your contract end date and count back 90 days to know when you should give the amendment notice.
Open Dubai REST or the DLD Rental Index service and run your unit through it.
Enter your current annual rent—not the new number your landlord is suggesting.
Take a screenshot of the average and the permitted increase.
Check your landlord’s proposed rent against the Decree 0 / 5 / 10 / 15 / 20% bands.
Reply in writing if the notice is late, the band is off, or you want to ask for a smaller increase.
Once you’ve agreed, update the Unified Tenancy Contract, cheque plan, and renew your Ejari.
Next Steps
The rental index is just the math behind renewals in Dubai’s bigger renting system. If you want the full picture, start with /renting-in-dubai/. And if your landlord’s number seems a bit off, check out /negotiate-dubai-rent/ for negotiation tips.
For notice, eviction, and disputes, keep /dubai-tenant-rights/ handy. Renew your registration through Ejari Registration, sort out payments with /dubai-rental-cheques/, and if you’re still looking for your first lease, check out Best Time to Rent in Dubai to see if timing can help.
Uncertain / confirm-before-you-rely: Exact building classification grades or star labels (DLD describes criteria; public star-band detail varies by secondary sources; trust the live calculator output for your building); whether a specific commercial/industrial unit is fully covered by the residential Smart rera rental Index expansion (confirm property type on the live DLD form).
Any mid-cycle UI or data refresh on Dubai REST after this draft’s 26 September 2026 verification. Decree 43’s English wording of the 10% / 11% boundary should be resolved via the official calculator and, if contested, Arabic text / RDC.
