In Dubai, a landlord cannot raise your rent by any amount they like. The permitted increase at renewal is capped by a sliding scale set out in Decree No. 43 of 2013, and the size of any legal increase depends entirely on how far your current rent sits below the market average for a comparable home, as measured by the RERA Rental Index (now the Smart Rental Index). If your rent is already close to the index average, the lawful increase in 2026 is zero.
- Permitted rent increases are tied to a five-step scale in Decree No. 43 of 2013 — ranging from 0% up to a maximum of 20%, never more.
- The increase is only allowed when your current rent is below the RERA/Smart Rental Index average for a similar property; the further below, the larger the cap.
- A landlord must give at least 90 days’ written notice before renewal to change any term, including rent (Law No. 33 of 2008).
- Check the permitted figure yourself for free on the Dubai Land Department website or the Dubai REST app before you accept or contest an increase.
- If a proposed rise exceeds the lawful cap, you can file a case with the Rental Dispute Settlement Centre.
How Dubai’s rent cap actually works
Dubai does not use a single flat percentage cap. Instead, the law compares your rent to the average rent for similar units in your area and lets the landlord close part — but not all — of that gap at renewal. This is the principle behind Decree No. 43 of 2013, which amended the earlier Decree No. 2 of 2011. The logic is deliberate: tenants paying well below market can face a larger (but still capped) correction, while tenants already paying at or near market are protected from any increase at all.
The comparison benchmark is the RERA Rental Index, maintained by the Real Estate Regulatory Agency under the Dubai Land Department (DLD). In January 2025 the DLD launched an upgraded version known as the Smart Rental Index, which the department says draws on Ejari-registered contracts, transactions and building data, and from 2026 layers in a building classification system (reported as A–D quality tiers) that can affect the benchmark for your specific building. Because the index is the reference point for the whole calculation, registering your tenancy contract with Ejari is what makes the system work in your favour.
The 2026 rent-increase bands
The table below sets out the statutory scale from Decree No. 43 of 2013. Read it as: “how far is my current rent below the index average for a comparable home?” — then find the maximum increase a landlord may apply.
| How far current rent is below the RERA/Smart Rental Index average | Maximum permitted increase |
|---|---|
| Up to 10% below the average | 0% — no increase allowed |
| 11% to 20% below the average | Up to 5% |
| 21% to 30% below the average | Up to 10% |
| 31% to 40% below the average | Up to 15% |
| More than 40% below the average | Up to 20% |
Source: Decree No. 43 of 2013. These percentages are fixed in the decree and are the ceilings — a landlord may propose less, but never more.
Two points trip people up. First, the percentage is applied to your current rent, not to the index value — so a 5% cap on a rent of AED 100,000 means a maximum rise of AED 5,000. Second, the bands are brackets, not a formula you negotiate: if your rent is 15% below the average, the landlord’s ceiling is 5%, full stop.
A worked example
Suppose you pay AED 90,000 for a one-bedroom apartment, and the Smart Rental Index average for a comparable one-bedroom in your community is AED 110,000. Your rent is roughly 18% below the average, which falls in the 11–20% band. The maximum lawful increase is therefore 5% of AED 90,000, or AED 4,500 — bringing renewal rent to no more than AED 94,500. If the landlord demands AED 105,000, that is not permitted for this renewal, regardless of what comparable listings advertise.
How to check your permitted increase in 2026
You do not need a broker or a lawyer to find your number. The DLD provides a free calculator, and checking it before any conversation with your landlord puts you on solid ground.
- Open the calculator. Use the rental index / RERA rental increase calculator on the Dubai Land Department website (dubailand.gov.ae) or inside the Dubai REST mobile app.
- Enter your property details. Area/community, property type, number of bedrooms, and your current annual rent.
- Read the result. The tool shows the index average for comparable units and the maximum permitted percentage increase for your contract.
- Compare to the landlord’s proposal. If the proposed figure is at or below the cap, it is lawful. If it exceeds the cap, you can decline it in writing.
One caveat worth knowing: some landlords and valuers now request a rental valuation certificate at renewal. Industry commentary in 2026 notes that, until RERA officially confirms a valuation certificate supersedes the index, the RERA/Smart Rental Index remains the reference point for the permitted-increase calculation. When in doubt, the DLD calculator result is the figure to rely on.
Notice periods and your renewal rights
Even when an increase is within the lawful band, a landlord cannot spring it on you. Under Law No. 33 of 2008 (amending Law No. 26 of 2007), the landlord must give at least 90 days’ written notice before the contract’s renewal date to change any term of the tenancy, including the rent. Miss that window, and the contract generally renews on the same terms. The notice requirement protects tenants from last-minute demands and gives both sides time to check the index and negotiate.
Tenants also have broad protection against eviction during a valid contract. Where a landlord wants to recover the property for sale or personal use, the law sets out specific grounds and a separate 12-month notice served through a notary or registered mail — a different process from a rent increase, and one worth understanding before you assume a renewal is at risk. If you are new to the system, our tenant guide to renting in Dubai and Ejari walks through registration and your core rights.
What landlords should know
The same rules protect landlords who play by them. If your tenant’s rent has fallen well below the index, the bands let you correct it in stages at each renewal — provided you serve the 90-day notice and stay within the permitted percentage. Trying to impose more than the cap usually ends the same way: the tenant checks the DLD calculator, refuses, and the increase is struck down if it reaches the dispute centre. Pricing new tenancies at the index average from the start avoids the problem entirely and keeps good tenants in place. Our landlord’s guide to Ejari and yields covers registration, pricing and returns in more depth, and if income is the goal, see how to earn passive rental income from Dubai property.
When there’s a dispute: the Rental Dispute Settlement Centre
If a landlord insists on an increase above the lawful cap, or there is any other disagreement over the tenancy, either party can file a case with the Rental Dispute Settlement Centre (RDSC), the judicial arm of the DLD that handles rental disputes. Filing requires the Ejari-registered contract, Emirates ID and supporting documents. The RDSC’s filing fee is widely reported as 3.5% of the annual rent, subject to a minimum of AED 500 and a maximum of AED 20,000 — confirm the current figure with the centre when you file. A valid, registered Ejari contract and the DLD calculator result are usually the two strongest pieces of evidence a tenant can bring.
Rent cap vs. buying: the 2026 trade-off
Rent caps give tenants real predictability, but they also mean rising markets eventually push renewal costs up within the bands year after year. Many long-term residents reach a point where the capped rent they pay approaches a mortgage payment on a comparable home. Whether that tips you toward ownership depends on how long you plan to stay, your deposit, and financing costs — we compare the maths in buying vs. renting in Dubai in 2026.

Frequently asked questions
Can my landlord increase my rent in Dubai in 2026?
Only if your current rent is below the RERA/Smart Rental Index average for a comparable property, and only up to the percentage ceiling set by Decree No. 43 of 2013. If your rent is within 10% of the index average, no increase is permitted this renewal.
What is the maximum rent increase allowed in Dubai?
The absolute maximum is 20%, and it applies only when your current rent is more than 40% below the index average. Smaller gaps allow 15%, 10%, 5% or 0%, per the Decree No. 43 of 2013 scale.
How do I check the RERA rental index for my apartment?
Use the free rental increase calculator on the Dubai Land Department website (dubailand.gov.ae) or the Dubai REST app. Enter your area, property type, bedrooms and current rent to see the index average and your permitted increase.
How much notice must a landlord give before raising rent?
At least 90 days before the renewal date, in writing, under Law No. 33 of 2008. Without valid notice, the contract generally renews on its existing terms.
What can I do if my landlord raises the rent above the legal cap?
Decline the increase in writing, cite your DLD calculator result, and if it is not resolved, file a case with the Rental Dispute Settlement Centre using your Ejari-registered contract as evidence.
Is the Smart Rental Index different from the RERA Rental Index?
The Smart Rental Index, launched by the DLD in January 2025, is the upgraded version of the RERA Rental Index. It uses the same decree-based increase bands but adds richer data, including a building classification system reported from 2026.
