Your Dubai landlord cannot raise your rent just because the market is hot. Increases are capped by the RERA rental index, a government database of average rents by area and unit type, and the cap works on a slab system. If your current rent is close to the market average, the legal increase is zero.
Two rules decide every renewal argument. First, the increase must fit the slab your rent falls into. Second, the landlord must give you 90 days written notice before the renewal date. Miss either condition and the increase is not enforceable.
Here is how to check your own numbers before renewal season.
The slab system in plain numbers
The permitted increase depends on how far your current rent sits below the index average for a similar unit in your area:
- Rent within 10% of the index average: no increase allowed
- Rent 11 to 20% below average: maximum increase of 5%
- Rent 21 to 30% below average: maximum 10%
- Rent 31 to 40% below average: maximum 15%
- Rent more than 40% below average: maximum 20%
Note what this means in practice: even a tenant paying half the market rate cannot face more than a 20% rise in one year. Landlords who quote "market rent" as justification for a 35% jump are bluffing.
How to check your unit
- Open the Dubai REST app or the Dubai Land Department website and find the rental index calculator.
- Enter your area, property type and number of bedrooms, plus your current annual rent.
- The calculator returns the maximum permitted increase for your unit, if any.
The result is tied to your Ejari-registered rent, which is one more reason the registered figure must match what you actually pay. If your contract was never registered, sort that first with our Ejari registration guide.
Screenshot the calculator result with the date visible. It is your evidence if the conversation turns into a dispute.
The 90-day notice rule
Any change to the contract at renewal, including a rent increase, requires written notice at least 90 days before expiry, unless your contract says otherwise. Email or registered post both count if you can prove receipt.
- Notice on day 89 or later: the increase fails, and the lease renews on the old terms.
- Notice given verbally: does not count. Ask for it in writing and keep the trail.
- A compliant notice with a non-compliant amount: you owe only the slab-permitted increase, not the demanded one.
The same 90-day rule protects landlords too, so if you plan to negotiate or leave, start the conversation early. If cash flow at renewal is the real problem, see whether paying rent monthly is an option in your building.
When the landlord will not back down
Stay calm and follow the sequence:
- Reply in writing with the calculator result and state the increase you accept (which may be zero).
- Keep paying on time. Withholding rent weakens your position.
- File at the Rental Dispute Centre (RDC) if no agreement is reached. Filing fees are a percentage of the annual rent, typically around 3.5% with minimum and maximum limits, so confirm the current schedule on the Dubai Land Department site. Many cases settle once a case number exists.
- Watch for retaliation moves. A landlord cannot evict you for refusing an illegal increase. Eviction has its own strict notice rules, covered in our tenant and landlord rights guide.
Also check the renewal invoice itself. Agents sometimes add "renewal fees" that have no legal basis, and we cover when renewal charges are illegal separately.
If yearly increases keep coming and your rent is approaching a mortgage payment, run the numbers on buying property in Dubai as an expat before signing another lease.
Key takeaway
A Dubai rent increase is only valid if it fits the RERA slab system and arrives in writing at least 90 days before renewal. Run your unit through the Dubai REST calculator before agreeing to anything. If both conditions are not met, you can lawfully renew at your current rent.
FAQ
Can my landlord raise the rent mid-contract?
No. Rent is fixed for the contract term. Increases can only take effect at renewal, and only with 90 days notice and within the slab limits.
What if the calculator says 0% but the landlord insists?
The index result is the legal ceiling. Reply in writing with the calculator output, keep paying your current rent, and file at the Rental Dispute Centre if the landlord refuses to renew on lawful terms.
Does the cap apply to new tenants?
No. The slab system protects sitting tenants at renewal. A landlord can ask any price for a vacant unit, which is why long-term tenants often pay below the index average.
Can the landlord evict me instead of renewing at the capped rent?
Not easily. Eviction at renewal requires 12 months notarised notice and a lawful ground, such as sale or personal use. Refusing a capped renewal is not a lawful ground.
