Your landlord can raise your rent in Dubai only if your current rent sits meaningfully below the market average, and even then the increase is capped: the ceiling is 20%, and if your rent is already within 10% of the Real Estate Regulatory Agency (RERA) index, no increase is allowed at all (Decree No. 43 of 2013, as of July 2026).

How much can your landlord actually raise the rent?

The answer is a fixed formula, not a negotiation. Under Decree 43 of 2013, the permitted increase depends entirely on how far your current rent sits below the average market rent for comparable units, measured by the RERA rental index. The further below the market you are paying, the larger the increase the law allows, up to a firm ceiling of 20%.

Here are the official bands, as of July 2026:

Two things in that table decide most disputes. First, if you are already paying close to the market rate, the law protects you completely: within 10% of the index average, the permitted increase is zero. Second, there is no band above 20%, whatever the gap. A landlord who finds the market has moved far above your rent still cannot raise it by more than a fifth in a single renewal.

How the RERA index sets your ceiling, and what changed in 2025

Everything hinges on one comparison: your current rent versus the RERA rental index average for units like yours. The index is built from actual Ejari-registered tenancy contracts and DLD transaction records, grouped by community, property type, bedroom count and built-up area (Ejari is the DLD system that officially registers your tenancy). It is a benchmark of what comparable homes actually rent for, not an asking-price list.

Since January 2025 that benchmark has run on the Dubai Smart Rental Index, and it remains the active system through 2026 with no major announced change as of July 2026 (Dubai Land Department). The Smart Rental Index added a building classification, a 1-to-5 star rating that weighs a building's structural condition, quality of finishes and maintenance, location, and the services and amenities on offer. A well-maintained, well-located building sits closer to the top of its market benchmark; a tired one sits lower. That rating shifts where your unit lands in the index, but it never removes the legal ceiling: the 20% cap in Decree 43 still applies on top of whatever the index shows.

A worked example makes the math concrete. Suppose your current annual rent is AED 80,000 and the index average for your unit type and community is AED 110,000. Your rent is about 27% below the average, which puts you in the 21% to 30% band, so the maximum lawful increase is 10%. Your rent could rise to at most AED 88,000 at renewal.

Now change one input. If you pay AED 95,000 and the index average is AED 100,000, your rent is only about 5% below the market. That is inside the 10% band, so the permitted increase is 0%. For context, a citywide 1-bedroom apartment rented for roughly AED 63,600 to AED 103,200 per year on March 2026 Bayut and Property Finder data, with a typical 1-bed near AED 70,000, so these are realistic figures, not abstractions.

How to check your exact legal increase

You do not have to take anyone's word for the number. RERA publishes a free Rental Increase Calculator that applies the index and the Decree 43 bands to your specific unit and returns both the permitted percentage and the AED figure. It is the same tool a dispute would rely on, so checking it first is the strongest move you can make before a renewal conversation.

1. 1

   Open the official calculator

   Use the RERA Rental Increase Calculator on the Dubai REST mobile app or the DLD website (dubailand.gov.ae). Both draw on the same Smart Rental Index data, so they return the same result.

2. 2

   Enter your contract and property details

   You will need your contract end date, property type (apartment, villa or hotel apartment), community, number of bedrooms, and built-up area. These are the fields the index uses to find comparable units.

3. 3

   Read the result against your current rent

   The tool returns the maximum lawful increase as a percentage and an AED amount, based on where your current rent sits below the index average. If it shows 0%, no increase is permitted at renewal.

4. 4

   Keep a copy

   Save or screenshot the result with its date. If a proposed increase exceeds what the calculator shows, that record is your starting point for a challenge.

The 90-day notice rule: the strongest protection tenants have

A lawful increase is only half the requirement. To change your rent, or any other term, at renewal, your landlord must notify you in writing at least 90 days before your contract expires, unless you both agree otherwise (Law No. 33 of 2008, as of July 2026). Miss that window and the change generally cannot be imposed for that renewal; the tenancy continues on the existing terms.

What counts as notice is specific. The law recognises a written notification delivered by a notary public, registered mail, hand delivery, or another legally approved technological method. A casual WhatsApp message or a verbal heads-up does not meet the standard. This is why the 90-day rule is, in practice, the single most useful thing a tenant can know: a large increase served late, or served informally, is a weak claim.

One more boundary matters. An increase applies only at renewal, never mid-lease. A landlord cannot raise the rent partway through a fixed term because the market moved; Decree 43 ties any change to the renewal of the contract.

What "new rules" mean in 2026

Searches for new rent rules usually trace back to the Smart Rental Index rollout, not a change to the cap itself. The sliding scale in Decree 43 is unchanged, and the 90-day notice rule is unchanged. What changed in January 2025 is how the index classifies your building: the 1-to-5 star system means two apartments of the same size in the same community can now sit at different points on the benchmark depending on the building's condition and amenities.

For a tenant, the practical effect is that the index figure behind your calculator result reflects your building's quality more precisely than the older flat-average approach did. It does not create a new way to raise rent beyond the 20% ceiling, and it does not shorten the notice period. When someone tells you the rules have changed, the accurate version is narrower: the benchmark got more granular, the limits did not move (Dubai Land Department, as of July 2026).

If you disagree: the Rental Disputes Centre

If a proposed increase breaks the cap or ignores the notice rule and the conversation stalls, the matter goes to the Rental Disputes Centre (RDC), the DLD body that settles tenancy disputes. The first step is not the courtroom, though: it is verifying the number against the official index, because a proposal that exceeds the calculator's result is on weak ground from the start.

1. 1

   Verify against the index first

   Run your unit through the RERA calculator. If the proposed increase is above the permitted band, or your rent is inside the 10% no-increase zone, you have the benchmark you need to push back.

2. 2

   Gather your records

   Keep your Ejari-registered contract, the landlord's written notice, and proof of your rent payments. These documents are what a case is built on.

3. 3

   File with the Rental Disputes Centre if needed

   If it cannot be resolved directly, file with the RDC. As of July 2026 the filing fee is 3.5% of the annual rent, with a minimum of AED 500 and a maximum of AED 20,000; verify the current fee before you file. Most matters are handled at the conciliation stage.

Will rent in Dubai increase in 2026?+

Whether your own rent can rise depends on your unit, not the market as a whole. Under Decree 43 of 2013 an increase is only permitted if your current rent is more than 10% below the RERA index average for comparable homes, and it is capped between 5% and 20% depending on the gap. If you are already paying close to the market rate, no increase is allowed at renewal.

Can my landlord increase my rent after 1 year?+

Only at renewal, and only within the Decree 43 bands. A one-year lease can be renewed with an increase if your rent sits far enough below the index and your landlord gave written notice at least 90 days before the contract expired. If your rent is within 10% of the index average, the permitted increase is 0%.

How much notice does my landlord have to give for a rent increase?+

At least 90 days before the contract expiry date, in writing, under Law 33 of 2008. Valid methods include a notary public, registered mail, or hand delivery; a WhatsApp message or verbal notice does not qualify. Without proper notice, an increase generally cannot be applied at that renewal.

What happens if I disagree with a rent increase in Dubai?+

Check the proposed figure against the RERA Rental Increase Calculator first. If it exceeds the legal band or the notice rule was not followed, you can raise it with your landlord and, if unresolved, file with the Rental Disputes Centre. Keep your Ejari contract, the written notice, and payment records to support the case.

How is the RERA rent increase calculated?+

It compares your current annual rent to the RERA index average for similar units in your community, now assessed through the Dubai Smart Rental Index. The percentage gap decides your band under Decree 43, from 0% up to a 20% ceiling. The official calculator on the Dubai REST app returns the exact figure for your unit.
