The Dubai Smart Rental Index is the Land Department's official reference for what a home should rent for, and it is the figure that decides whether a renewal increase is lawful at all. People search for it under several names: the RERA rental index, the Dubai rental index, the rent increase calculator. They are the same tool. This guide explains what the index measures, how the increase bands in Decree No. (43) of 2013 work, what to prepare before you open the calculator, how to run it on the right unit, what the result does and does not do, how to read listings and comparables next to it, what tenants and landlords should each document, and what happens when the two sides still disagree.
What does the Dubai Smart Rental Index measure?
It estimates the rental value of a home from registered tenancy information rather than from advertised asking prices. Decree No. (43) of 2013 refers to it as the Rent Index of the Emirate of Dubai, approved by the Real Estate Regulatory Agency (RERA), which is why many people still call it the RERA rental index. Dubai Land Department (DLD) describes the current version as an AI-assisted system covering residential areas, special development zones and free zones, and it works at a finer level than a broad area label.
The step that changed most at the launch of the new index on 2 January 2025 is building classification. The DLD gives each building a rating, and that rating, together with the registered rents in the building and its area, feeds the value the index returns. Two towers on the same street can sit in different classes, so an older, poorly maintained building does not inherit the rents of a newer one next door. At launch, the DLD said the rating applied to the whole building, that an owner who upgrades the building can have it reappraised, and that the rating was visible to the building owner rather than to tenants. Those details reflect what was published in January 2025 and can change; run the official service on the DLD channels or the Dubai REST app rather than relying on a forwarded screenshot.
How do the rent increase bands work?
The permitted increase is set by law, not by negotiation. Decree No. (43) of 2013 Determining Rent Increase for Real Property in the Emirate of Dubai (issued 18 December 2013) ties the maximum increase at renewal to how far the current rent sits below the average rental value of similar units as shown by the index.
| Current rent compared with the index value | Maximum increase at renewal (Decree 43/2013, Article 1) |
|---|---|
| Up to 10% below | No increase |
| 11% to 20% below | Up to 5% of the rent |
| 21% to 30% below | Up to 10% |
| 31% to 40% below | Up to 15% |
| More than 40% below | Up to 20% |
Read the table as a ceiling, not an entitlement. A landlord may propose less, and a tenant may negotiate on terms other than rent, such as the number of cheques or a longer fixed period. Article 2 of the decree applies it to landlords in Dubai whether private or public, including special development zones and free zones such as the DIFC. The text is on the Dubai legislation portal; verify the slabs there and on the DLD service before you rely on them.
What should you prepare before opening the rent increase calculator?
Have the tenancy in front of you, not your memory of it. The calculator asks for details that must match the registered contract, and most wrong results come from a wrong input rather than a wrong index.
- The current tenancy contract and the Ejari certificate.
- The present annual rent as written in the contract, not the amount of one cheque.
- The contract start and expiry dates for the renewal period under discussion.
- The property type, the area, the building or project name and the unit details as registered.
- The number of bedrooms, counted as the contract counts them.
- Any renewal clause or agreed notice provision in the contract.
- Written correspondence already exchanged about the renewal.
Use the DLD website or the Dubai REST app, not a third-party calculator that does not explain its data source. If the building name, unit type or registered rent in the records does not match your documents, fix the record first and run the calculation afterwards.
How do you run the index on the right unit?
Treat the query as a description of the actual tenancy and check each field against the contract.
- Match the exact building and project name as they appear on the tenancy contract, not as they appear in a listing, and do not pick a dearer neighbouring community because it looks comparable in an advertisement.
- Match the unit type and the number of bedrooms, and check that a study or maid's room has not been counted as a bedroom.
- Use the contract dates that apply to the renewal period, not today's date.
- Confirm the tenancy is registered and current, because an unregistered or lapsed record undermines every later step.
- Save the dated result with a screenshot or reference number. The records behind the index update over time, so a result from months ago is not evidence of today's figure; run it again close to the renewal date.
- Where you can, agree with the other party to run the calculation on the same inputs. Most arguments about the index are arguments about inputs.
What does the result mean, and what does it not do?
The result tells you whether an increase is permitted at renewal and, if so, the ceiling for it. That is all it does. It does not amend the contract, collect the rent, renew the Ejari registration or settle a dispute on its own. It does not prove that one apartment should rent for the same as every other unit in the building either: condition, layout, furnishing and view still shape the negotiation, but they cannot be used to step outside the ceiling.
Nor does the index override the tenancy contract. The contract still sets the term, the payment schedule, the maintenance split and the conditions for early exit, and Ejari registration still evidences that the tenancy exists in the form both sides claim. Our guide to Ejari in Dubai: How to Register, Renew and Cancel a Tenancy Contract covers the registration side.
Why is a listing price not enough evidence?
An asking rent is an advertisement. It shows what a landlord hoped for, sometimes for months, not what a tenant agreed to pay. Portals also carry duplicate units, stale advertisements, holiday-home rates, promotional rents and properties with very different specifications, so a single screenshot proves little in a renewal conversation.
A sound review uses three layers. The official index result comes first. The registered contract and the notice history come second. A small set of truly comparable units, used for negotiation context only, comes third. When a comparable has three unknown fields, it is an anecdote with a number attached, not evidence.
How do you compare rents properly?
Separate three numbers before comparing anything. The asking rent is the advertisement. The contracted rent is real, because it sits in a signed tenancy registered through Ejari, but it still bundles concessions and payment terms that differ from one deal to the next. The effective rent is the contracted rent adjusted for explicit concessions and expressed on one annual basis, and it is the only number that belongs in a decision.
To normalise a comparable, take the gross rent for the committed term, subtract rent-free periods and any landlord contribution such as fit-out or agency fees, divide by the term in months and annualise. Record the number of cheques beside every comparable, because in Dubai annual rent is commonly paid in one to four instalments and a single cheque usually buys a discount; that is a financing difference, not a market difference. Keep furnished and unfurnished evidence in separate groups, and note who pays cooling, because a lease where the landlord absorbs the district-cooling charges is a different deal from one where the tenant pays them (see Chiller-Free Meaning in Dubai: District Cooling vs Chiller-Free and What Buyers Should Check).
Then adjust for property differences honestly: bedrooms, usable area, floor, view, parking, condition, building age and the date of the lease. State the direction of each adjustment and carry a range rather than a single figure. A comparable that needs many large adjustments tells you more about your assumptions than about the market, so drop it. Start inside the same building, then the same cluster, then the same micro-market; the further you travel, the less the result means.
What is the 90-day notice rule?
Under Article 14 of Law No. (26) of 2007, as amended by Law No. (33) of 2008, a party that wants to change the rent or any other term at renewal must notify the other party at least 90 days before the contract expires, unless the parties have agreed otherwise. A result from the index does not rescue a notice served after that window. Eligibility for an increase and a valid notice are two separate questions, and both must be answered yes before the increase applies.
Keep the notice, the way it was sent and the date it was received. Verbal messages and scattered chats make the timeline hard to prove later. The detailed rules, including what happens when neither side gives notice, are in Dubai Tenancy Renewal: How the 90-Day Notice Rule Works in 2026.
What should a tenant do when the result looks wrong?
Separate three different problems, because they have different remedies. The first is a data problem: the index has the wrong building, the wrong unit type or a classification that does not match the property. The second is a notice problem: the landlord wants a new rent but did not give written notice at least 90 days before expiry. The third is a genuine disagreement about value.
Only the third is a negotiation. For the first, use the official correction route and keep the reference number. For the second, reply in writing, state the date the notice was received, and keep the contract, the Ejari record and the correspondence in one file. Ask for the proposed figure in writing, run the official calculator on the same unit data, compare the result with the contract, and do not stop paying rent or take legal steps on the strength of informal advice. Start the conversation early enough that the contract does not expire without a plan.
What should a landlord document before serving notice?
A landlord who wants an increase to hold up should be able to produce four things without hunting: the registered tenancy contract, the dated index result for the correct unit, proof that written notice was served at least 90 days before expiry, and a record of what was delivered to the tenant over the term, including maintenance.
The notice itself should state the current rent, the proposed rent and the date the new rent is meant to take effect. Relying on what similar units are advertised for is the most common mistake: an asking price is a hope, a registered contract is evidence. If the classification or the property record looks wrong, correct it through the official route before the renewal conversation, not after the tenant refuses. When the two sides agree, record the new rent and term in the renewed contract and the new Ejari registration. Landlords screening a new tenant rather than renewing will find the checks in Tenant Screening for Dubai Landlords: Documents, Affordability, References and Data Privacy.
Does the index affect eviction notices?
No. The eviction routes sit in a different article of the law and run on their own clock. Under Article 25(2) of Law No. (26) of 2007 as amended by Law No. (33) of 2008, a landlord may seek eviction at the end of the contract only for the reasons the article lists: demolition and reconstruction, restoration or comprehensive maintenance that cannot be carried out while the tenant is in occupation, the owner's own use or that of a first-degree relative, or sale of the property. In each case the landlord must notify the tenant of the reason at least 12 months before the eviction date, through a notary public or by registered mail. A rent discussion does not shorten or lengthen that period. The valid reasons and the common mistakes are set out in Dubai Eviction Notice in 2026: Valid Reasons and the 12-Month Rule.
What happens if the two sides still disagree?
First compare inputs. Many disagreements dissolve once both parties run the calculator on the same building, unit type, dates and current rent. Then put the index result, the current rent, the proposed rent and the notice dates on one page and ask whether the gap is worth a case.
A rent disagreement that cannot be settled goes to the Rental Disputes Centre (RDC). The RDC's published fee for rental cases is 3.5% of the annual rent, with a minimum of AED 500 and a maximum of AED 20,000, plus small fixed charges listed on rdc.gov.ae, so the cost of a dispute is proportionate to the tenancy and can be estimated before anyone files. The filing steps and documents are in How to File a Rental Dispute in Dubai Through the RDC (rdc.gov.ae) in 2026. A calculator result does not allow either side to ignore the contract, the payment procedure or the eviction rules while the case is pending.
How does this affect someone buying a tenanted unit?
A buyer of a tenanted apartment inherits the lease and its renewal position, not a blank slate. Before committing, run the index on that unit, read the registered contract, check the renewal date and check whether notice has already been served and by whom. If the current rent sits close to the index value, model the holding period on roughly the rent you see, because the permitted increase may be zero.
Use effective rent, not asking rent, as the income line, and keep it apart from your cost calculation. Vacancy allowance, leasing commission, management, service charges, maintenance and any financing belong in a second worksheet; normalise the gross rent first, then apply costs. Ask for the payment record too: a tenancy at an attractive rent is only attractive if the rent has actually been paid. The handover and rights questions are in Buying a Tenanted Property in Dubai in 2026: Rights, Rent and Handover.
When does this apply?
The index and the increase bands apply to residential tenancy renewals in Dubai under the emirate's rental legislation, including special development zones and free zones under Article 2 of Decree 43/2013. They apply at renewal, not mid-term, and not to a vacant unit offered to a new tenant, where the rent is simply agreed. At the January 2025 launch the DLD said the new index did not yet cover non-residential property. The bands do not apply to licensed short-term holiday-home letting, which sits under a different regime, and they do not apply in other emirates, which set their own rules.
Bottom line
Treat the Smart Rental Index as evidence, not as a verdict. Prepare the contract and Ejari certificate, run the calculator on the correct building, unit type and contract dates, save the dated result, and read it next to the 90-day notice timeline rather than instead of it. Use listings for context and effective rent for decisions. Landlords who document the index result and serve notice properly rarely end up in a dispute. Tenants who reply in writing, fix data errors through the official route and keep one organised file rarely lose one. Rules and figures here reflect the decree, the law and the RDC fee schedule as published and checked in October 2026; verify on the official channels before you act.
Asking, contracted or effective rent: which number do you compare with the index?
Three different numbers get called "the rent". An asking rent is an advertisement and proves only what a landlord hoped for. A contracted rent is real because it sits in a signed tenancy registered through Ejari, but it still bundles concessions and payment terms. The effective rent is what remains after you strip those out, and it is the only basis on which comparables, or your own renewal position, can be compared honestly.
· Convert every comparable to one annual basis. A 12-month lease at 120 with one rent-free month is 110 a year; a 24-month lease at 110 with two rent-free months across the term is about 101 a year.
· Record the payment frequency: one cheque, two, four or twelve changes the value of the same headline figure to the landlord.
· Note what is included: furniture, district cooling, chiller charges, parking and the service-charge allocation all move the number.
· Adjust for property differences honestly (floor, view, condition, layout) and use several comparables, not one.
· Keep market rent and an investor's cash flow apart: the Smart Rental Index tells you the permitted increase band for a registered contract, not what a unit will let for tomorrow.
Landlord and tenant checklists before a renewal conversation
Landlord, before requesting an increase: run the official DLD / Dubai REST calculator on the exact registered unit and the current contracted rent, keep a dated screenshot or reference number, check that the 90-day written notice can still be served in time, and prepare the comparables that support the figure. A calculator result does not amend the contract, collect rent or renew Ejari by itself; record the agreed rent in the renewed contract and the new Ejari registration.
Tenant, before responding: match the proposal to the contract and the Ejari certificate (unit, rent, dates), re-run the calculator yourself from the registered rent rather than the requested one, check when and how the notice was served, and remember that a tenant may also ask for a lower rent at renewal where the index supports it. If the two sides still disagree after the evidence is exchanged, the Rental Disputes Centre decides; a calculator screenshot is evidence, not an order.
Frequently asked questions
Is the Smart Rental Index the same as asking prices in listings?
No. Listings show what landlords hope to achieve; the index draws on registered information and building classification. A tower full of ambitious advertisements can still sit below the index, and a quiet building with strong registered contracts can sit above it. Use the official result for the renewal conversation and treat listings as background.
Can a landlord raise the rent by more than the band allows?
Not unilaterally at renewal. Decree 43/2013 sets the ceiling according to how far the current rent sits below the index value. A tenant who receives a demand above that ceiling should respond in writing and keep the dated index result. Where the parties cannot agree, the Rental Disputes Centre decides.
Can a tenant ask for a lower rent at renewal?
Yes. The 90-day notice in Article 14 works for either party, so a tenant may propose a reduction or a change of terms on the same timeline. If the two sides do not agree, the contract, the index and the Rental Disputes Centre become the references; the decree caps increases, it does not fix the rent at the current level.
Does the index cover free zones?
The DLD states that the system covers residential areas, special development zones and free zones, and Decree 43/2013 applies to landlords in those zones. Even so, run the query on your exact building rather than assuming coverage, and if the property cannot be identified in the service, treat that as a data issue to resolve through the official support route before the renewal date.
What if my building is classified incorrectly?
Raise it through the official correction or support channel with the property details and any supporting documents, and keep the reference number. Do not treat a result you believe rests on wrong data as final, and do not ignore it either. Fix the record first, then have the renewal conversation on the corrected figure.
Should Ejari be updated after the renewal, and what should the file contain?
Yes. The renewed registration should reflect the agreed term, rent and conditions. Keep the registered contract, the dated index result for the correct unit, proof of the notice and how it was served, payment records and all written correspondence, with photographs if condition is part of the discussion. One organised folder answers most questions in a negotiation and almost all of them in a dispute.
