If you rent in Dubai, or own a property that you lease out, the RERA Rental Index is the most important number in your financial life. It is the government benchmark that determines whether a rent increase is legal, how much a landlord can charge, and how much protection a tenant has when renewal time comes around.
And yet, most people either don't know it exists or don't know how to use it properly. This guide changes that.
What Is the RERA Rental Index?
The RERA Rental Index (now officially called the Dubai Smart Rental Index) is a database maintained by Dubai Land Department (DLD) that shows the registered average rent for every property type in every community across Dubai.
It was originally introduced under RERA (Real Estate Regulatory Agency) to protect both landlords and tenants from arbitrary rent movements. Since its 2023 upgrade to the "Smart Rental Index", it has become more granular, accounting for building age, quality, and condition rather than just community-level averages.
In practical terms: before a landlord can increase your rent, they must check the Smart Rental Index. If the gap between what you are paying and the index figure is within a certain threshold, no increase is permitted at all.
Taraf Holding Tip: If you're buying an investment property in Dubai, understanding the rental index isn't optional, it directly shapes your rental income projections. See our guide on how to calculate ROI and rental yield in Dubai for the full investor picture.
How the Smart Rental Index Works: The Percentage Bands
The law governing rent increases in Dubai is Law No. 43 of 2013, administered by RERA. The Smart Rental Index determines the permitted increase based on how much below the index your current rent sits:
Importantly, even if your rent qualifies for an increase, the landlord must give you 90 days' written notice before the renewal date. Failing to do so means they lose the right to increase rent for that contract year.
We covered the notice period rules and tenant rights in more detail in our article on whether a landlord can increase rent in Dubai after one year.
The 2023 Upgrade: From Rental Index to Smart Rental Index
Prior to 2023, the RERA Rental Index assessed rent by community only. A studio in a 30-year-old building was compared to the same area as a studio in a brand-new tower, which was clearly unfair to both sides.
The Smart Rental Index changed this by factoring in:
- Building age and condition (assessed by inspectors)
- Building classification (A, B, C, D rating)
- Specific unit type and floor level
- Services and facilities available in the building
The result is a more accurate benchmark. A landlord with a well-maintained, high-rated building can justify higher rents than the community average; tenants in older, lower-rated buildings gain stronger protection against unjustified increases.
How to Use the RERA Rental Calculator (Step-by-Step)
DLD provides a free online tool to check whether a proposed rent increase is legal. Here is how to use it:
- Go to the DLD Smart Rental Index tool at: dubailand.gov.ae → Services → Rental Index
- Select the property type: apartment, villa, or commercial
- Enter the community / area name (e.g. Jumeirah Village Circle, Dubai Marina, Business Bay)
- Enter the number of bedrooms
- The calculator returns the registered index range for that property type in that community
- Compare your current rent to the index figure, the gap tells you which percentage band applies
Pro Tip: The Smart Rental Index now also allows you to look up a building by its exact name or Ejari number, not just by community. This gives you a more precise benchmark than the old area-level averages.
What the Index Means for Landlords
For property owners, the Smart Rental Index is both a ceiling and a floor. It sets the maximum increase you can apply, but it also confirms the market rate, which helps you price a vacant unit competitively without leaving money on the table.
Key practical points for landlords:
- Check the index before issuing any renewal notice, if you increase rent without legal basis, a tenant can file a RERA dispute and the increase will be reversed
- Building classification matters. Investing in maintenance and upgrades can move your property into a higher classification band, unlocking higher permissible rents
- If your unit has been well below market for several years, you may be eligible for a larger increase, but only if the gap from the index supports it

What the Index Means for Tenants
If your landlord issues a rent increase notice, here's exactly what to do:
- Check the Smart Rental Index yourself at dubailand.gov.ae, it's public and free
- Calculate the gap: (Index Average − Your Current Rent) ÷ Index Average × 100
- Look up which percentage band that gap falls into (see table above)
- If the proposed increase exceeds the permitted band, you have the right to reject it
- If the landlord insists, file a dispute with the Rental Disputes Centre (RDC), part of Dubai Courts
The filing fee at the RDC is typically 3.5% of the annual rent (minimum AED 500, maximum AED 20,000). Most disputes are resolved within a few weeks.
What the Index Means for Property Investors
If you're buying property in Dubai with the intention of renting it out, the Smart Rental Index should be part of your due diligence before purchase. Here's why it matters for investment decisions:
- If the current tenant in a unit you're buying is paying well below the index, you have a clear roadmap for increasing rent at renewal, within legal limits
- If rents in a community are already at the top of the index range, your upside is more limited, factor this into yield calculations
- Index data acts as a sanity check against developer projections, if a developer promises 10% rental yield but the index shows rents that don't support it, that's a red flag
