What is the Smart Rental Index, and how do I use it?

The Smart Rental Index is the official online tool that helps you check if a rent increase is legal. It replaced the older RERA rent calculator in 2025. The tool compares your rent with the average market rate for your area and building type, and shows if your landlord can increase it, and by how much.

Can a landlord raise rent without notice in Dubai?

No, rent cannot be increased without written notice. Under RERA rules, landlords must inform tenants of any rent changes at least 90 days before the lease renewal date. If they miss this deadline, the rent stays the same for the next term.

Do the RERA rent rules apply in all Emirates?

No, RERA rules apply specifically to Dubai. Other Emirates, like Abu Dhabi and Sharjah, have their own rent regulations and authorities. However, most follow a similar structure to keep rent adjustments fair and transparent.

How often can a landlord increase rent in Dubai?

A landlord in Dubai can increase rent only once every 12 months, and only at contract renewal. The increase must fit the Smart Rental Index brackets under Decree No. 43 of 2013, and written notice is required at least 90 days before the lease ends.

What is the maximum rent increase allowed in Dubai?

The highest legal rent increase in Dubai is 20%, and it applies only when the current rent sits more than 40% below the market benchmark. Rent within 10% of the benchmark cannot be raised at all.

Can a landlord evict a tenant just to raise the rent?

No. A landlord cannot evict a tenant only to charge a higher rent. Eviction needs valid grounds, such as sale or personal use, plus 12 months' written notice served through a notary public or registered mail.

Can rent be increased in the middle of a contract?

No. Rent stays fixed for the full term of the tenancy. A change can take effect only at renewal, and only with 90 days' written notice before the current lease ends.

Which Dubai areas see the biggest rent increases?

The steepest legal increases hit tenants whose rent has fallen far below the current market rate, most common in high-demand communities where rents have climbed fast, such as Dubai Marina, Business Bay, and Jumeirah Village Circle.

How much does it cost to file a rent dispute in Dubai?

Filing a case at the Rent Disputes Settlement Centre (RDSC) costs about 3.5% of the annual rent, with a minimum of AED 500 and a cap of AED 20,000. The centre often orders the losing side to cover the fee.

What should tenants check before signing a new lease in Dubai?

Before signing, a tenant should confirm the rent fits the Smart Rental Index benchmark, the contract is registered on Ejari, and the renewal and exit clauses are clear. A comparison with recent rents in the same community, whether Dubai Hills Estate, Arjan, or Dubai Creek Harbour, flags an overpriced unit early.

How Rent Increases Are Calculated Under RERA Index

A lease renewal notice lands, and the new rent comes in higher than last year. The first question on any tenant's mind is whether that increase is even allowed. Dubai has firm rules on this, and since January 2025 the Smart Rental Index sets the fair rent for every home and limits how much a landlord can add at renewal. Once the rules are clear, checking a rent figure takes only a few minutes. The guide below walks through how the index calculates rent, the increase limits by percentage, how to run the check, the rights that protect tenants, and what to do when a landlord asks for more than the law allows.

What is the smart rental index?

Anyone working out how to rent a property in Dubai meets the Smart Rental Index sooner or later, since it sets what counts as a fair price. Dubai Land Department (DLD) launched the current version in January 2025, and it replaced the old RERA rent calculator. It runs on AI and reads live data from Ejari-registered contracts, so the benchmark tracks real properties for rent in Dubai rather than guesswork.

The 2025 upgrade added building classification. Every building now carries a rating from 1 to 5, scored on construction quality, finishes, maintenance, location, and amenities. A higher-rated building supports a higher benchmark rent than a lower-rated one on the same street.

A tenant's rent gets measured against that benchmark. The gap between the two decides whether a rent increase is allowed and how large it can be. The index is not only a tenant tool. A landlord who plans to rent your property out uses the same benchmark to set a legal asking price.

How are rent increases calculated?

The allowed rent increase depends on how far the current rent sits below the market benchmark for the area and building type. DLD sets the limits under Decree No. 43 of 2013, using Ejari contract data. The building classification now feeds into that benchmark, so two flats in the same area can carry different fair-rent figures.

Rent less than 10% below the benchmark: No increase allowed.
Rent 11% to 20% below: Up to 5% increase.
Rent 21% to 30% below: Up to 10% increase.
Rent 31% to 40% below: Up to 15% increase.
Rent more than 40% below: Up to 20% increase. The new rent still cannot pass the area average.

The law behind these rules

Decree No. 43 of 2013 sets every one of these limits and holds landlords to one standard across Dubai. The Smart Rental Index applies the same brackets when it checks a proposed increase against official data.

Example

Take a two-bedroom apartment in Al Nahda, Dubai, where similar units average AED 60,000 a year. At a current rent of AED 45,000, the figure are about 25% below the market average. That falls in the 21% to 30% band, so the landlord can raise the rent by up to 10%. The renewal rent could reach AED 49,500, and it cannot exceed the AED 60,000 area average.

Tools to check your rent increase

Any proposed increase can be checked against the Smart Rental Index before a tenant signs.

Step 1

Open the Smart Rental Index. Go to the Dubai Land Department website or open the Dubai REST app. The tool is free and works for anyone, tenant or landlord. No agent or paid account is needed to run a basic check.

Step 2

Enter the details. Select the area, property type, number of bedrooms, and lease renewal date. Enter the current annual rent exactly as it reads on the Ejari contract. Accurate details matter here, since a wrong figure changes the whole result.

Step 3

Review the benchmark. The tool shows the current benchmark rent for similar units in that area and building classification. It then measures the current rent against that figure and shows how far below or above the market it sits. That gap sets the legal increase.

Step 4

Check the legal increase. The result shows whether the landlord can raise the rent and by how much, based on the Decree No. 43 of 2013 brackets. Save a copy or a screenshot of the output. It works as proof if the two sides disagree.

One of the simplest tips for tenants looking for a new rental is to run this index check before signing, not after. It takes the guesswork out of a first-year rent and flags an overpriced unit early.

Tenant rights under the law

Decree No. 43 of 2013 sets out these protections.

The maximum any landlord can add is 20%, and only when the rent sits more than 40% below market.
No increase when close to market. Rent within 10% of the benchmark stays flat at renewal.
Any increase above the legal bracket can be challenged. The Smart Rental Index proves the correct figure.
A landlord must give written notice at least 90 days before renewal to change the rent. Miss the deadline, and the rent holds for the next term.
The Smart Rental Index compares a current rent against the market rate for the property type and building.
A complaint can be filed with the Rent Disputes Settlement Centre (RDSC) if an increase breaks the decree. Its decision is binding.

One more point worth knowing. Sub-leasing in Dubai needs the landlord's written consent, so the unit cannot be rented on to someone else without it.

What to do if the landlord raises rent illegally?

An increase above the legal bracket is not the final word. These four steps show how to challenge it and where to file if the landlord refuses to back down.

Step 1

Confirm the increase is illegal. Run the numbers through the Smart Rental Index to check the demand against the legal bracket. If the figure the landlord wants sits above what the index allows, the increase is not valid. Save the result before going further.

Step 2

Put it to the landlord in writing. Send the index result to the landlord by email or a documented message. A clear figure often settles it without a fight. Written proof also protects the tenant if the case moves ahead.

Step 3

File with the Rent Disputes Settlement Centre. If the landlord holds firm, file a complaint with the Rent Disputes Settlement Centre (RDSC). It can be filed online through the DLD website or in person at the RDSC office. There is a filing fee, so factor that in.

Step 4

Bring the Ejari certificate, tenancy contract, payment receipts, and any written exchange with the landlord. The RDSC reviews the case against these records and issues a binding decision that the landlord and tenant must follow.
