How Rent Is Regulated in Dubai: RERA Rental Index and Rent Increase Rules

The Dubai RERA rental index helps landlords and tenants assess whether a rent increase is permitted when an existing tenancy contract is renewed. Dubai's rental regulations establish maximum increase percentages based on how far the current rent falls below the applicable rental benchmark. The Dubai Land Department's Smart Rental Index and official Rental Index Calculator help users assess the property-specific rental value and potential increase.

Quick Answer

Dubai rent increases are governed by rental legislation, including Decree No. 43 of 2013, and administered through the Dubai Land Department (DLD). Under the decree's percentage bands, the maximum increase ranges from 0% to 20%, depending on the difference between the existing rent and the average rental value of comparable properties. Landlords and tenants should check the official rental calculator, review the tenancy agreement and confirm the applicable notice requirements before agreeing to a renewal.

How does the Dubai rental index work?

The Dubai rental index helps establish the rental benchmark used to assess whether a rent increase is permitted at renewal. In January 2025, the Dubai Land Department introduced the Smart Residential Rent Index, which uses building classifications and property-related criteria to improve rental assessments.

According to the Dubai Land Department's Smart Rental Index guidance, building classifications consider factors such as construction quality, architectural design, energy efficiency, provided services and strategic location. Rental assessments also consider location, technical classification, services and market conditions.

This means two apartments in the same neighbourhood may receive different rental assessments even when their layouts are similar. Building quality, available facilities and other relevant characteristics can affect the comparison.

Advertised rents for nearby apartments may provide useful market context, but they do not independently establish the permitted increase for an existing tenancy. The official index is the more appropriate starting point when checking a proposed renewal.

The official Dubai Land Department Rental Index Calculator allows users to enter the required tenancy and property information to assess rental values and potential increases.

For tenants, the calculator provides a practical way to check a landlord's proposal. For landlords, it helps establish a more informed basis for renewal discussions rather than relying solely on advertisements or informal estimates.

The index should be considered alongside the applicable legislation, the tenancy agreement and the renewal circumstances. The calculator supports the assessment, while the applicable law establishes the legal framework.

How much can rent increase in Dubai?

Under Article 1 of Dubai Decree No. 43 of 2013, the maximum permitted rent increase at renewal ranges from 0% to 20%, depending on how far the existing rent falls below the average rental value of similar properties.

The decree establishes the following percentage bands.

Existing rent below average rental value	Maximum permitted increase
Up to 10% below	0%
11% to 20% below	5%
21% to 30% below	10%
31% to 40% below	15%
More than 40% below	20%

Source: Dubai Decree No. 43 of 2013, Article 1.

These are maximum increases, not automatic annual adjustments. A landlord cannot assume that a 10% or 20% increase is justified simply because advertised rents in the area have risen.

The Smart Rental Index adds building-specific assessment to the process. Therefore, landlords and tenants should check the current official result for the property rather than rely exclusively on a general market comparison.

A practical rent increase example

Suppose an apartment has an annual rent of AED 60,000 and an applicable comparable rental value of AED 80,000.

The existing rent is 25% below the assumed benchmark.

Calculation:

(AED 80,000 − AED 60,000) ÷ AED 80,000 × 100 = 25%

Under the percentage bands in Decree No. 43 of 2013, a difference of 25% falls within the 21% to 30% band, allowing a maximum increase of 10%.

Item	Amount
Current annual rent	AED 60,000
Assumed comparable rental value	AED 80,000
Maximum increase under this example	10% A quick check while you read Is whoever is advising you actually on your side? Take the free ADVICEdge check
Increase in annual rent	AED 6,000
Annual rent after the increase	AED 66,000

This is an illustration of the decree's calculation framework, not a live assessment of a specific apartment. The AED 80,000 benchmark is an assumption. The actual permitted increase should be checked through the official service using the correct property and tenancy information.

How to use the RERA rent calculator in Dubai

The most reliable starting point is the official Dubai Land Department calculator. It allows landlords and tenants to assess rental values using the information requested for their property category.

Follow these steps before agreeing to a renewal.

1. Open the official Rental Index Calculator.
2. Select the appropriate property category, such as residential.
3. Enter the tenancy contract expiry date and select the property type.
4. Provide the requested property identification and location details.
5. Enter the current annual rent and any additional information required.
6. Review the result and save a copy for your records.

The required fields differ between property categories. Depending on the selection, the calculator may request an Ejari contract number, a municipality number, the area, bedroom count or other property details. Follow the fields displayed for your property rather than assuming every category requires the same information.

The Dubai Land Department also lists digital channels, including the Dubai REST app, for accessing rental index services.

What if the calculator result differs from the landlord's demand?

Check the property details, current annual rent and contract expiry date first. An incorrect property selection or inaccurate tenancy information can affect the assessment.

If the difference remains, ask the landlord or property manager to explain the proposed increase in writing. Keep the official calculator result, existing tenancy contract, Ejari details and renewal communications together.

If the parties cannot resolve the disagreement, they can seek guidance from the Dubai Land Department or the Rental Disputes Center about the appropriate next step.

What notice must a landlord give before increasing rent?

Under Article 14 of Dubai Law No. 26 of 2007, as amended by Law No. 33 of 2008, a party seeking to amend tenancy terms must generally notify the other party at least 90 days before the contract expires, unless the parties have agreed otherwise.

The notice requirement and the permitted rent increase are separate matters. A proposed increase may fall within the relevant percentage band, but the parties must also check whether the applicable notice requirements have been met.

For example, if a tenancy contract expires on 31 December 2026, 90 days before expiry is approximately 2 October 2026. This is an illustrative calculation. The exact deadline should be checked against the contract and applicable legal requirements.

Tenants and landlords can reduce misunderstandings by following four steps:

1. Review the contract expiry date and renewal provisions.
2. Keep a written record of the proposed change and when notice was received.
3. Check the official rental assessment separately from the notice deadline.
4. Respond in writing if the proposed rent or notice timing is disputed.

The applicable provisions are available in the official text of Law No. 33 of 2008.

Before renewing, it is also useful to understand the wider Dubai tenancy contract and tenant rights framework, including the importance of written agreements, renewal terms and tenancy documentation.

How rent regulation affects Dubai property investors

Rental regulation affects an investor's income forecast because the rent written into an existing tenancy contract may not be immediately adjustable to match advertised market rates.

Imagine an investor considering an occupied apartment with an annual rent of AED 70,000. Similar properties are advertised for AED 90,000. The investor should not assume that the existing tenancy can immediately be increased to AED 90,000. The applicable rental assessment, contract expiry date, permitted increase and notice requirements must be reviewed first.

This distinction matters when assessing a property's expected return.

Start with the existing contractual rent. For an occupied property, use the current lease as the starting point for your cash flow forecast rather than assuming the latest advertised market rent will be immediately achievable.

Account for timing. A potential increase may only be relevant at renewal and must comply with the applicable requirements. Do not automatically include an assumed increase from the beginning of an ownership period.

Calculate net rental income. Service charges, maintenance, property management fees, vacancy periods and financing expenses can reduce the amount retained by the owner. Gross rental yield alone does not show the full investment picture.

Review the tenancy before purchasing. Examine the contract, Ejari details, payment schedule, expiry date and any notices already served. These records help establish what rental income can reasonably be expected.

The Dubai net rental yield calculator can help you assess potential income after selected operating costs. For broader property investment decisions, Dubai real estate advisory services can help you evaluate rental assumptions, operating expenses and investment risks as part of your due diligence.

When should you seek professional advice?

Seek professional guidance if the official calculator produces an unexpected result, a proposed increase appears inconsistent with the applicable rules, the notice deadline has passed or the disagreement may develop into a formal rental dispute.

Before seeking help, prepare your signed tenancy contract, Ejari certificate, current annual rent, proposed renewal amount, contract expiry date, written notices and official calculator result.

A property adviser can help review rental assumptions and organise the relevant information. For advice on legal rights or representation in a dispute, consult a qualified UAE lawyer or the appropriate Dubai authority. Special jurisdictions and unusual lease arrangements may require additional review.

The objective is to establish the facts before making a decision. Neither a landlord's estimate nor a tenant's interpretation should replace the applicable law and official rental assessment.

Conclusion

The Dubai RERA rental index gives landlords, tenants and property investors a practical starting point for understanding rent regulation. Check the applicable rental benchmark, confirm the permitted increase, review the notice requirements and retain the supporting documents.

Before agreeing to a renewal or forecasting rental income, use the official calculator and review the circumstances of the specific tenancy. A careful assessment can help reduce avoidable disagreements and support more realistic property decisions.

Frequently asked questions

1. Does the rental index apply to furnished and unfurnished properties?

The assessment depends on the property category and the information accepted by the Dubai Land Department's service. Select the correct property type and verify the result through the official calculator instead of assuming every unit is assessed identically.

2. Can a landlord increase rent every year?

A rent increase is not automatic at every renewal. The permitted amount depends on the applicable regulations and rental assessment, and any proposed change must also meet the relevant notice requirements.

3. What happens if the landlord and tenant cannot agree on the renewal rent?

Both parties should compare the proposed amount with the official rental assessment and review the tenancy agreement and notices. If the disagreement remains unresolved, they can seek guidance from the Dubai Land Department or the Rental Disputes Center.

4. Should an investor rely on advertised rents when buying an occupied property?

Advertised rents can provide market context, but they do not establish the rent that can immediately be charged under an existing tenancy. Investors should examine the current lease, renewal date, applicable rental assessment and operating costs before projecting income.

5. Where can I check my property's rental assessment?

Use the official Dubai Land Department Rental Index Calculator and enter the property and tenancy details requested for the relevant category. Save the result and compare it with the proposed renewal amount before making a decision.
