Dubai RERA Rental Index Explained: How Rent Increases Work (2026)

The RERA rental index is Dubai's official rent benchmark, run by the Real Estate Regulatory Agency under the Dubai Land Department. It compares your current rent to the average market rent for similar units in your area. That comparison decides whether your landlord can raise your rent at renewal, and by how much.

Direct answer. A landlord cannot raise your rent freely. The maximum legal increase is set by the RERA rental index calculator, applied under Dubai Decree No. (43) of 2013 on the relationship between landlords and tenants. The three things to know:

• The index compares your rent to the average for your area and unit type.
• If your rent is already close to the market average, no increase is allowed.
• The exact percentage brackets are set by RERA and can change, so always check the live calculator before any renewal.

What is the RERA rental index?

The RERA rental index is a database of average rents across Dubai, sorted by location, building, and unit type. The Real Estate Regulatory Agency (RERA) maintains it under the Dubai Land Department (DLD). It exists to stop arbitrary rent hikes and to give both tenants and landlords a neutral reference point.

When you enter your details into the RERA rental index calculator, it tells you two things. First, the average market rent for units like yours. Second, the maximum percentage your landlord may legally increase your rent at renewal. That output is the legal ceiling, not a suggestion.

The index is updated periodically as market data changes. Two identical flats in different communities can have very different permitted increases, because the index works on local averages, not a single citywide rate.

Think of the index as a fairness check rather than a price list. It does not tell your landlord what to charge a new tenant. It only governs how much an existing rent can move at renewal. For that reason, the number that matters is always the one tied to your specific area, building, and unit type. A figure that applies to a neighbouring community, or to a different size of unit, has no bearing on your own renewal.

Why the index matters under Dubai law

The index matters because it converts a vague idea of a fair rent into an enforceable legal limit. The controlling rule is Dubai Decree No. (43) of 2013, which sets out when and by how much rent may rise at renewal. It builds on Dubai Law No. (26) of 2007 on landlord-tenant relations, as amended by Dubai Law No. (33) of 2008.

Decree No. (43) of 2013 ties the permitted increase to how far your current rent sits below the average market rent shown in the RERA index. The further below the average you are, the larger the increase your landlord may apply. If your rent already matches or exceeds the market average, the rule does not permit any increase at all.

This is why the index, not the landlord's preference, is the deciding factor. A landlord who demands more than the index permits is acting outside the law, and you can challenge it. The percentage bands themselves are set by RERA and can change over time. So confirm the current figures with the Dubai Land Department or a licensed UAE lawyer before you accept or reject a renewal offer.

If your dispute escalates, the body that hears it is the Rental Disputes Settlement Centre (RDSC), the tribunal attached to the Dubai Land Department. We cover that route in our guide to Dubai tenancy disputes and the RERA process.

How to check your RERA rental index

Checking your index takes a few minutes and is the single most useful step before any renewal conversation. Here is the practical sequence.

1. Open the official tool. Use the RERA rental index calculator on the Dubai Land Department website at dubailand.gov.ae, or the Dubai REST app, which RERA operates.
2. Enter your unit details. You provide the area, property type, number of bedrooms, and your current annual rent.
3. Read the two outputs. The calculator shows the average market rent for your unit type and the maximum legal increase percentage for your renewal.
4. Save a copy. Take a screenshot or print the result with the date. This is your evidence if the landlord asks for more than the index allows.
5. Compare to the landlord's offer. If the proposed increase is at or below the calculator's ceiling, it is lawful. If it is above, it is not.

The Dubai REST app and the DLD website are the only sources you should trust for this number. Third-party rent estimators are not the legal index and carry no weight in a dispute.

Notice rules: the 90-day requirement

The index sets the amount, but timing has its own rule. Under Dubai Decree No. (43) of 2013, a landlord who wants to change any term of the lease at renewal, including the rent, must notify the tenant in writing. That notice has to reach you at least 90 days before the lease ends, unless both sides agree otherwise.

This matters in two ways:

• A rent increase that arrives later than the 90-day window is generally not enforceable for that renewal, even if the amount itself sits inside the index.
• The same 90-day notice principle protects you. If you receive nothing, your existing rent and terms usually roll over automatically.

If you are facing a renewal notice or a possible eviction alongside a rent demand, read our explainer on the Dubai 12-month eviction notice and template. It walks through the details so you can tell a lawful notice from an invalid one.

Common mistakes tenants and landlords make

Most rental-index problems come from a handful of avoidable errors. Watch for these.

• Trusting a verbal figure. Only the live RERA calculator output, dated and saved, counts. A WhatsApp number does not.
• Using a stale screenshot. The index updates over time. Re-run the calculator at each renewal rather than relying on last year's result.
• Confusing market rent with permitted increase. The average market rent is a reference; the permitted increase is the legal ceiling. They are different numbers.
• Missing the 90-day notice window. Tenants who do not track the deadline can be pressured into accepting an increase that was served too late to be valid.
• Skipping [Ejari](/dictionary/ejari). A registered Ejari tenancy contract is the foundation for any index claim or dispute. Without it, you have a much weaker position.
• Assuming the index is negotiable. It is a legal limit, not an opening bid. A landlord cannot lawfully exceed it, whatever the lease says.

When to involve a lawyer

Most renewals settle once both sides see the calculator output. You should consider professional help when the situation moves beyond a clear number.

Talk to a lawyer if your landlord insists on an increase above the index, serves a defective notice, threatens eviction to force a higher rent, or refuses to renew without legal grounds. A real-estate lawyer can file at the Rental Disputes Settlement Centre on your behalf, prepare your Ejari and index evidence, and respond to an unlawful demand in writing.

Costs and timeline expectations

Checking the RERA rental index itself is free on the DLD website and the Dubai REST app. Filing a case at the Rental Disputes Settlement Centre carries a government fee, which is calculated as a percentage of the annual rent and is set by the Dubai Land Department. Because that fee schedule is fixed by the authority and can change, confirm the current figure with the DLD or a licensed UAE lawyer before filing.

Timelines vary. A straightforward index disagreement can resolve in a single exchange of letters. A contested case at the RDSC typically moves faster than ordinary civil litigation, but the exact duration depends on the centre's caseload and the complexity of your matter.

It helps to keep your expectations realistic and your paperwork ready. Most tenants never reach the filing stage at all, because a dated calculator result tends to settle the question on its own. The clearer your evidence, the shorter the road. Where a case does proceed, an organised file of your tenancy contract, your saved index output, and the landlord's written demand will move things along more smoothly than a dispute argued from memory.

Frequently asked questions

The questions below cover what tenants and landlords most often ask about the Dubai rental index.

Your next step

Run your unit through the official RERA rental index calculator on the Dubai REST app or dubailand.gov.ae before any renewal talk. Save the dated result. If your landlord asks for more than the index permits, or serves a late or defective notice, you have grounds to push back.

For tailored help, you can ask the free LEXAI AI assistant a first question at any time, or browse real-estate lawyers and reach out directly.
