RERA Rental Index Dubai: What the Rent Cap Means for Airbnb vs. Long-Term Owners
How Dubai's rent-increase index works, and what it actually means if you're deciding between a long-term tenant and short-term rental income.
What Is the RERA Rental Index, and Why Does It Cap Long-Term Rent
If you own a rental property in Dubai and lease it long-term, the amount you can raise the rent at renewal isn't up to you. It's set by the Real Estate Regulatory Agency's (RERA) rental index, a Dubai Land Department benchmark that tracks average rents by area, building, and unit type. When a long-term tenancy comes up for renewal, the index tells you whether your current rent is already at market level, and if it isn't, exactly how much you're allowed to raise it. It's a legal cap that landlords can't negotiate around, enforced under Decree No. 43 of 2013, applying to every standard residential tenancy contract registered through Ejari in Dubai. Landlords who increase rent beyond what the index permits can have the excess struck down at the Rental Disputes Settlement Centre if a tenant contests it.
The index exists because Dubai's rental market moves fast, and a landlord locked into a below-market rent could otherwise try to catch up in one large jump at renewal, which is exactly the kind of shock the cap is designed to prevent. It works by comparing your current annual rent to the RERA-published average for comparable units nearby, then applying one of five fixed increase bands depending on the size of that gap.
The Rent Increase Bands: How Much a Landlord Can Legally Raise Rent
The bands themselves haven't changed since 2013, and every landlord renewing a long-term lease in Dubai works within them:
| Current Rent vs. Market Average | Maximum Legal Increase |
|---|---|
| Up to 10% below average | 0% (no increase allowed) |
| 11% to 20% below average | Up to 5% |
| 21% to 30% below average | Up to 10% |
| 31% to 40% below average | Up to 15% |
| More than 40% below average | Up to 20% (maximum) |
Source: Decree No. 43 of 2013 (Dubai Land Department), unchanged bands, cross-confirmed 13 Aug 2026.
Two things follow from this. First, if your rent already sits at or above the market average for your building and unit type, you can't raise it at all at the next renewal, regardless of how long the tenant has been in place. Second, even in the best case for a landlord, a rent more than 40% below market, the increase is capped at 20% for that single renewal cycle: a landlord can't jump straight to market rate in one step, it happens gradually, cycle by cycle, as the tenant renews. Landlords must also give 90 days' written notice before the contract's end date to propose any increase, or the existing rent carries over automatically for another term.
The Smart Rental Index: What Changed in 2025 (and What Didn't)
On 2 January 2025, the Dubai Land Department launched the Smart Rental Index, an upgrade to how the RERA benchmark itself is calculated. Instead of relying on the older, periodically-updated average, the new system pulls in live Ejari contract data and classifies buildings on more granular factors: location, condition, finish quality, maintenance standard, and available facilities. In practice, that means the market-average figure your rent gets compared against is now more current and more specific to your actual building, not just your area.
What the Smart Rental Index didn't change is the increase bands themselves. The same 0%, 5%, 10%, 15%, 20% tiers from Decree No. 43 of 2013 still apply, only the input data got more precise. If you're checking your own numbers, use the official calculator on the Dubai REST app or the Dubai Land Department website, since a more accurate building classification can shift which band you actually fall into compared to older estimates.
Why This Cap Doesn't Apply to Short-Term Rental Income
Here's the distinction that matters if you're weighing a long-term tenant against listing the same unit on Airbnb: the RERA rental index governs tenancy contracts registered through Ejari. A short-term or holiday-home rental booked through Airbnb, Booking.com, or a management company is a licensed short-term letting activity under Dubai's Department of Economy and Tourism (DET), not a tenancy in that legal sense, so nightly or weekly rates aren't subject to any RERA increase cap.
That means an owner running a short-term rental can raise or lower pricing constantly, week to week, based on demand: higher rates during Dubai Shopping Festival or New Year's Eve, adjusted rates around a slower August, and everything in between. A long-term landlord capped at a maximum 20% increase, once, at a single annual renewal, has no equivalent flexibility. Long-term letting isn't automatically the worse choice here, just a differently-paced one: the two paths run on fundamentally different pricing mechanics, worth understanding before deciding which one fits a given property.
The Real Decision: Capped Long-Term Renewal vs. Uncapped Airbnb Yield
This is exactly the comparison our Dubai Property ROI Calculator is built to run: input a property's numbers and see the short-term rental income estimate against a long-term rental estimate, side by side. The RERA index explains one half of why that gap exists. A long-term rent is anchored to whatever the index allowed at the last renewal, which itself is anchored to an area average from months (now, closer to real-time under the Smart Rental Index) earlier. Short-term rental income responds to actual demand as it happens.
That said, the RERA index is also useful information, not just a constraint to work around: if the index shows a unit's long-term rent is already close to or above the area average, a long-term tenant may be capturing most of the achievable long-term value already, and the real comparison becomes long-term rent (however it's capped) against short-term yield, not how much more could be charged long-term. Dubai's long-term rental market has also been softening, with Dubai's long-term asking rents cooling roughly 6.7% year-on-year as new residents increasingly rent short-term first while they house-hunt, another reason the short-term side of that comparison is worth running the actual numbers on rather than assuming.
When a Long-Term Tenant Under RERA Still Makes Sense
None of this makes short-term rental automatically the better choice. A long-term tenant means one contract, one deposit, no turnover costs, no cleaning between guests, and no seasonal demand risk. If a property sits in a location with thin tourist or corporate-stay demand, or an owner wants predictable income without active management, a RERA-capped long-term rent, even capped, can still be the more practical choice. The rent increase limit is a ceiling on how fast income can grow, not a ceiling on whether long-term letting is worthwhile at all.
What Changes If You Switch a Long-Term Rental to Airbnb
Switching an Ejari-registered long-term tenancy over to short-term rental means the RERA rental index stops applying once the conversion happens: DTCM holiday home permit rules take over instead, and pricing is no longer capped. If you've already gone the other way, moving from Airbnb back to a long-term let, we've covered exactly what changes in that direction in our guide to converting a Dubai Airbnb back to long-term rental (the Ejari-registration and notice-period considerations largely mirror what's described there, just in reverse).
How Royale Stays Handles the Short-Term Side
If the numbers point toward short-term rental, Royale Stays runs it from 15%: furnishing, photography, dynamic pricing, guest communications, check-in, and maintenance coordination, so pricing can actually respond to demand instead of sitting capped at a RERA-set ceiling. As a Dubai Airbnb management company, we handle the DTCM permit process, the guest-facing side, and the day-to-day so an owner isn't running two jobs.
