There is no single UAE-wide rental index governing every emirate. Abu Dhabi, Dubai and Sharjah operate different systems with different legal effects. In September 2026, Abu Dhabi has a temporary 0% renewal increase, Dubai uses its Smart Rental Index to calculate permitted renewal increases, while Sharjah combines rental indicators with a statutory three-year rent rule.

Oplus International Realty compares the three systems so tenants and landlords use the correct tool.

Which UAE Rental Index Should You Use?

Emirate	Official Tool	Authority	Main Purpose	Current Renewal Rule
Abu Dhabi	Residential Rental Index / Market Data	ADREC	Indicative area rental benchmarks	Temporary 0% increase
Dubai	Rental Index / Smart Rental Index	Dubai Land Department	Calculate market rent and permitted renewal increase	0%–20% according to index and law
Sharjah	Rental Indicators / Rental Map	Sharjah City Municipality	Fair-rent and area-rent reference	Generally no increase for first 3 years

The key point is that these are not interchangeable calculators.

A tenant renewing in Abu Dhabi should not use Dubai’s percentage bands.

A Dubai tenant should not apply Sharjah’s three-year rule.

And a Sharjah landlord should not treat an advertised portal rent as the Municipality’s fair-rent determination.

Is There a Federal UAE Rental Index?

No official federal rental-index calculator covering all seven emirates was identified during this September 2026 review.

Rental regulation remains substantially emirate-specific.

The earlier version of this guide said authorities were moving toward a “nationwide unified rental database”.

That statement has been removed because no current official source verified it.

For tenants, the practical rule is:

Start with the authority for the emirate where the property is located.

Abu Dhabi Rental Index: Market Benchmark, Not Exact Legal Rent

Abu Dhabi Real Estate Centre launched the emirate’s first residential Rental Index in August 2024.

ADREC describes the index as providing:

• indicative rental values;
• quarterly rental pricing;
• residential market transparency;
• area-based information across Abu Dhabi.

The current interactive map allows users to explore rental data by location and property type.

But ADREC includes an important disclaimer:

The Rental Index is a general guide based on aggregate data and should not be used as a legal reference for establishing the exact rental value of an individual residential unit.

That distinction has become particularly important in 2026.

Abu Dhabi Has a Temporary 0% Rent-Increase Measure

On 3 June 2026, Abu Dhabi temporarily reduced the annual rental increase percentage from 5% to:

0%

ADREC states that residential, commercial and industrial tenancy renewals across the emirate are to be processed with no increase for the duration of the measure, which remains described as temporary and effective until further notice.

As of this review on 15 September 2026, ADREC’s current news centre continued to display the 0% measure without a later announcement ending it.

That creates two different Abu Dhabi questions

Question 1: What is the current market rent in my area?

Use the ADREC Rental Index and market data.

Question 2: How much can my existing rent increase at renewal right now?

Under the current temporary measure:

0%.

The market benchmark and the legal renewal position are not the same thing.

Abu Dhabi Rents Can Rise While Renewals Stay Frozen

This is one of the clearest examples of why rental-index data must be interpreted correctly.

ADREC’s H1 2026 market report recorded:

233,000 active residential lease contracts

with a combined value of:

AED 9.3 billion.

ADREC also reported that new-lease prices increased year-on-year by:

• 17% for apartments;
• 9% for villas;
• 21% for apartments in investment zones;
• 16% for villas in investment zones.

Yet existing-contract renewal increases are temporarily set to:

0%.

Both facts can be true at the same time.

A new tenant entering the market and an existing tenant renewing a registered contract are not necessarily subject to the same pricing dynamic.

What Rent Is Used During Abu Dhabi’s Temporary Measure?

ADREC states that renewals and new agreements during the measure reference the rental rate from the property’s last registered:

Tawtheeq contract.

For a tenant dealing with an unusual situation — for example a major contract restructuring or dispute — the registered contract and current ADREC guidance should be checked rather than relying only on an index screenshot.

How to Use the Abu Dhabi Rental Index

Use ADREC’s interactive rental map as a market benchmark.

A practical sequence is:

1. open the ADREC Rental Index / interactive map;
2. choose the relevant Abu Dhabi location;
3. select the applicable residential property category;
4. review the indicative area rental values;
5. compare the benchmark with the property’s registered rent;
6. separately check the current rent-increase regulation.

Do not use the area average to declare that one specific apartment must legally rent at exactly that number.

Two units in the same neighbourhood can differ because of:

• building;
• age;
• condition;
• view;
• floor;
• layout;
• services.

Dubai Rental Index: The Renewal Calculator

Dubai works differently.

Dubai Land Department’s current Rental Index service specifically allows users to calculate:

• average market rent;
• permitted rental increase.

The current service asks for information including:

• contract end date;
• property type;
• area or property identifier;
• number of rooms where applicable;
• current annual rent.

The calculation is available immediately through DLD digital channels including the DLD website and Dubai REST.

What Makes Dubai’s Smart Rental Index Different?

Dubai Land Department launched the Smart Rental Index in 2025.

The system moved beyond an area-only comparison and incorporates factors including:

• building rental contracts;
• average area rents;
• building classification;
• property location;
• technical characteristics;
• services;
• building quality and maintenance.

This matters because two buildings in the same neighbourhood may no longer be treated as though they were identical products.

Dubai Rent-Increase Bands

Dubai’s current rental-increase framework applies maximum permitted increases according to how far the existing rent sits below the applicable average rental value.

Existing Rent Compared With Market Average	Maximum Increase
Up to 10% below average	0%
11%–20% below	5%
21%–30% below	10%
31%–40% below	15%
More than 40% below	20%

These bands are set out in Dubai’s rent-increase decree and are applied through the current rental-index framework.

Example

Suppose:

Current annual rent:

AED 80,000

Applicable average market rent:

AED 100,000

The current rent is:

20% below the market benchmark.

That falls in the 11%–20% band.

The maximum increase would therefore be:

5% of AED80,000 = AED4,000

giving a maximum renewal rent of:

AED84,000

subject to the applicable notice and tenancy conditions.

Dubai’s 90-Day Notice Rule Still Matters

Being eligible for an increase under the index does not automatically mean the landlord can simply change the rent at renewal.

Dubai Land Department’s current FAQ states that when either party wants to reconsider rental terms or rental value, the other party should generally be notified at least:

90 days before contract expiry

unless the parties agree otherwise.

DLD has also clarified that where the Smart Rental Index supports an increase but the landlord did not provide the required advance notice, the increase does not apply in the normal renewal process described by DLD.

For the full tenancy-law framework, use the Dubai RERA tenancy law guide.

Does the Dubai Index Apply to New Leases?

DLD’s current FAQ draws an important distinction.

For a new lease, the rental index is described as indicative rather than mandatory.

For a dispute about the permitted rate of increase on a renewal, the rental-index framework becomes materially more important.

That means:

Asking rent for a vacant apartment and permitted increase on an existing tenant’s renewal are different questions.

This is a recurring source of confusion.

Does the Dubai Rental Index Cover Free Zones?

DLD’s Smart Rental Index announcement describes broad residential coverage including special-development and free-zone areas.

However, DLD’s current FAQ specifically states that its residential index covers Dubai residential areas, including free zones and privately developed areas, excluding DIFC.

Therefore a DIFC tenancy should not simply be run through the ordinary DLD framework without checking the rules applicable inside DIFC.

Sharjah Rental Index: Use the Municipality’s Rental Indicators

Sharjah City Municipality currently lists a:

Rental Indicators Inquiry Service

within its Rent Regulation Department services.

Sharjah also operates an interactive Rental Map.

The Municipality describes that map as a tool enabling landlords, tenants and investors to search using factors including:

• geographical location;
• average rental value;
• other property specifications.

But just as in Abu Dhabi, market-rent information is only part of the answer.

Sharjah has its own statutory timing rules for increases.

Sharjah’s Three-Year Rent Rule

Law No. 5 of 2024 concerning Property Leasing in Sharjah establishes the core rule:

A landlord generally cannot increase the agreed rent before:

3 years

from the start of the rental relationship, unless the parties agree otherwise.

If the tenant accepts an increase before the three-year period expires, the landlord generally cannot impose another increase until:

2 years

have passed from that accepted increase.

After the relevant protected period, an increase is based on the property’s:

fair rent / rent of equivalent property

under the applicable regulatory framework.

For examples and the municipality workflow, use the detailed Sharjah Rental Index 2026 guide.

Sharjah Example

Suppose a residential tenancy begins on:

1 October 2025

at:

AED 50,000 per year.

In the ordinary scenario, the landlord cannot simply increase the rent at the October 2026 renewal because market rents elsewhere have risen.

The statutory three-year protection is the first question.

Now suppose the tenant voluntarily accepts an early rent increase in 2026.

The law then creates a separate two-year restriction before another increase can generally occur.

That is fundamentally different from Dubai’s percentage-band model.

UAE Rental Index Comparison: Same Rent, Three Different Outcomes

Consider three tenants each currently paying:

AED 80,000 per year.

Assume market evidence suggests a comparable property might command AED100,000.

Abu Dhabi

Current temporary renewal measure:

0% increase

despite wider market movement.

Dubai

AED80,000 is 20% below AED100,000.

Under Dubai’s index bands, the maximum increase can fall into the:

5% band

subject to the required notice and exact DLD index result.

Sharjah

The first question is not the percentage difference.

It is:

How long has the rental relationship existed, and has any earlier increase been agreed?

If the statutory protected period is still running, the market comparison alone does not permit an ordinary increase.

This is why there is no meaningful single “UAE rent-increase calculator”.

Rental Index vs Asking Rent

A property portal shows:

what landlords are asking today.

An official rental index or registered-contract dataset can answer a different question.

That difference matters.

For example:

• portal listing = advertised expectation;
• registered contract = rent actually recorded;
• rental index = authority benchmark/calculation;
• rent law = what can legally happen to an existing tenancy.

Do not substitute one for another.

Rental Index vs Registered Rent

The most relevant evidence for a renewal is often not simply the average asking rent in the neighbourhood.

In Abu Dhabi, the current temporary rule expressly references the property’s last registered Tawtheeq rent.

In Dubai, the Rental Index calculation uses the contract and property information and sits within the Ejari tenancy framework.

In Sharjah, Municipality rental-regulation services include tenancy-contract and rental-indicator functions.

Registered tenancy records matter.

Which Tool Should a Tenant Use Before Renewal?

Abu Dhabi tenant

Check:

1. registered Tawtheeq rent;
2. current ADREC rent-increase measure;
3. ADREC Rental Index for market context.

Dubai tenant

Check:

1. Ejari contract expiry;
2. notice date;
3. DLD Rental Index result;
4. permitted increase band.

Sharjah tenant

Check:

1. start date of rental relationship;
2. whether an earlier increase was accepted;
3. statutory three-year/two-year timing;
4. Municipality Rental Indicators for fair-rent context.

That is the practical emirate-by-emirate workflow.

Which Tool Should a Landlord Use?

The same official tools apply, but the question is different.

A landlord should distinguish:

What rent could a vacant property achieve?

from:

What increase can be applied to the current tenant?

These are not necessarily the same number.

A rising market does not automatically allow an equivalent percentage increase on every existing tenancy.

Which Tool Should an Investor Use?

Rental indices can help an investor estimate market depth and rental benchmarks.

They should not be used alone to calculate expected investment yield.

For an investment property, combine the relevant official rental evidence with:

• exact purchase price;
• unit size;
• building;
• service charges;
• vacancy assumptions;
• property management;
• maintenance;
• financing.

An area’s average rent is not automatically the achievable rent for one specific apartment.

Abu Dhabi Market Data Is Now Much Deeper Than One Index

ADREC’s current market-data platform includes metrics covering:

• residential leased units;
• rental values;
• apartment rental-price indices;
• villa rental-price indices;
• historical average annual rents;
• rental pricing by area and product.

That makes Abu Dhabi’s market-data environment useful not only to tenants but also to investors comparing areas.

But the legal renewal rule must still be checked separately.

Do Rental Indices Guarantee “Fair Rent”?

No.

“Fair” can mean different things:

Market fair value

What comparable units are renting for.

Statutory permitted renewal

What the law permits the landlord to charge the existing tenant.

Contractual rent

What the parties have actually agreed and registered.

These can produce three different numbers.

The official index is evidence.

It is not always the entire legal answer.

Can a Landlord Ignore the Index Because Similar Listings Cost More?

Not safely.

In Dubai, renewal increases are tied to the official rental-index framework.

In Sharjah, statutory timing restrictions apply.

In Abu Dhabi, the current temporary 0% measure overrides the normal annual increase during its operation.

A listing screenshot does not replace the applicable regulation.

Can a Tenant Demand the Lowest Rent Shown in the Index?

Not necessarily.

Rental indices often provide:

• averages;
• ranges;
• indicative values;
• calculation inputs.

They do not necessarily create an automatic right to replace an agreed contract with the lowest displayed number.

For example, ADREC explicitly states that its Rental Index should not be used as the legal reference for fixing the exact value of an individual residential unit.

Renewal vs Moving to a New Property

A tenant considering a large apparent market gap should calculate both options.

Renewing may involve:

• regulated increase;
• no moving cost;
• no new deposit;
• no moving company;
• no utility relocation;
• known building.

Moving may involve:

• new market asking rent;
• deposit;
• agency fee where applicable;
• moving cost;
• different commute;
• different property quality.

A cheaper advertised unit can be more expensive after total relocation costs.

Frequently Asked Questions

Use the Correct Emirate Before Using the Number

The most important rule is simple:

Abu Dhabi ≠ Dubai ≠ Sharjah.

For Abu Dhabi, start with ADREC’s market framework and Oplus Abu Dhabi area guides.

For Dubai rental-law questions, use the Dubai RERA tenancy guide and the updated Dubai Land Department guide.

For Sharjah renewals, use the dedicated Sharjah Rental Index 2026 guide.

If you are comparing areas before signing a new tenancy rather than checking an existing renewal, contact Oplus International Realty with your budget, property type, workplace and preferred emirate.
