Landlord Raising Your Rent in Dubai: Is It Legal, and How to Dispute It — 2026

A message from your landlord with a new rent figure is scary before you've even had a chance to check whether the number is legal at all. Here's the good news: a rent increase in Dubai isn't "whatever you agree to" — it's a specific formula with a hard cap that you can check yourself in an official calculator in a couple of minutes. Below: how the RERA rent increase scale actually works, what changed with the new Smart Rental Index, whether landlords are required to give 90 days' notice, and exactly what to do, step by step, if they're asking for more than the law allows — from pushing back in writing to filing with the Rental Dispute Centre (RDC).

One thing upfront: everything below applies to Dubai, for contracts registered in Ejari. Abu Dhabi, Sharjah, and the other emirates run their own rules and their own rent indices — don't assume Dubai's scale applies there.

How the RERA scale works: 0/5/10/15/20%

The whole system is based on comparing your current rent to the average market rate for comparable units in the same area. The further your rent sits below that average, the more the landlord is legally allowed to raise it at renewal.

The scale under Decree No. 43 of 2013:

An important detail people frequently get wrong: if your rent is already at or above the market rate, the landlord isn't allowed to raise it at all — the scale only ever works "upward," compensating for rent that's below market, not letting a landlord raise the price just because "rents went up everywhere." An increase can only happen at renewal — the law doesn't allow changing the amount mid-contract.

The Dubai REST calculator: checking your own number

Checking takes a few minutes and doesn't require a lawyer at this stage. The steps:

1. Open the RERA rental index calculator — either on the Dubai Land Department website (dubailand.gov.ae) or in the Dubai REST app.
2. Enter the property type (apartment/villa/office), the area (community/building), and the size.
3. Enter your current annual rent under the existing contract.
4. The system compares that figure to the market average (or, where the Smart Rental Index applies, to the rate adjusted for that specific building's star rating) and tells you whether — and where — your case falls on the increase scale.
5. Save a screenshot or PDF of the result — it's your first piece of leverage in writing to the landlord, and potential evidence at RDC.

If the calculator shows 0%, or a lower figure than the landlord is asking for, that's grounds for a written objection — not a reason to just pay up quietly.

Smart Rental Index 2026: what changed

Since January 2025, the Dubai Land Department has been shifting from the old annual index to the Smart Rental Index — a system that assigns every residential building in Dubai a star rating from 1 to 5 based on 60+ factors: building age and condition, finish quality, available amenities, management quality, and location. According to several industry sources, the system runs on data analysis (some descriptions mention AI-based classification), and unlike the old index's annual updates, it's designed to be refreshed on an ongoing basis.

The practical effect: instead of one average rate "for the area," the benchmark increasingly ties to the specific building and its star rating — meaning neighboring buildings in the same area can end up with different allowed increase caps. Sources differ on exactly how fully the new system has replaced the old index across all areas and property types as of mid-2026 — the safest way to know the current status for a specific address is to check the Dubai REST calculator directly at the time you need it, and if the tool's result and the landlord's demand don't match, get that checked by a lawyer.

The 90-day notice: a mandatory step

Even if the percentage itself falls within the RERA scale, the increase is invalid if the notice doesn't meet the required form and timing. Law No. 26 of 2007, as amended by Law No. 33 of 2008 (Article 14), requires:

• the notice must be in writing — a phone call, a conversation, or a WhatsApp message has no legal weight;
• it must be given at least 90 days before the current tenancy contract's expiry date;
• in practice, the reliable way to serve it is through a notary public or another officially recognized delivery channel, so the fact and date of notice are documented.

If the 90-day period isn't met, sources describe the increase as invalid, and the contract renews on the previous rent terms until the next renewal cycle. This is one of the most common grounds for successfully disputing an inflated rent increase — a landlord can be right about the percentage and still be wrong about the notice timing.

What to do if the landlord is asking for more than allowed

If the number in the increase notice is higher than what the RERA calculator shows:

1. Check the calculation in Dubai REST — save the result with the date you checked it.
2. Check the notice date — compare it against the contract's expiry date in Ejari; if the gap is less than 90 days, that's grounds for an objection on its own, regardless of the percentage.
3. Respond to the landlord in writing — by message, letter, or through your agency — attaching a screenshot of the calculator and stating the legal percentage instead of the one requested. Many disputes get resolved at this stage without going to court.
4. If the landlord pushes back — restate your position in writing again and offer to renew at the figure confirmed by the calculator; keep every message.
5. If you can't reach an agreement — file a complaint with the Rental Dispute Centre (RDC). It's the specialized body under the Dubai Land Department that handles, among other things, disputes over rent increases above the RERA cap — for the full step-by-step on filing, documents, and fees, see the separate guide on the Rental Dispute Centre.

One more thing worth knowing: if, alongside the rent increase, the landlord is hinting — or outright telling you — to move out if you don't accept the new price, that's a different scenario with its own notice rules, covered in the guide on eviction from a rented apartment in Dubai. And if the dispute isn't really about the rent itself but about a withheld deposit tied to the renewal, that's a separate issue — see the guide on the rental deposit in Dubai.

Common tenant mistakes

• Taking the landlord's word for it ("this is legal, trust me"). The percentage needs to be checked in the calculator yourself — a verbal assurance carries no evidentiary weight.
• Ignoring a missed 90-day notice just because the percentage itself "seems reasonable." A notice-timing violation is grounds for a dispute on its own, even if the percentage technically fits the scale.
• Paying the new amount by post-dated cheques before the dispute is resolved — in practice this is often treated as tacit acceptance of the new price.
• Confusing a rent increase with general market inflation — the law ties the cap to how far your specific rent sits below the average (or, under the Smart Rental Index, below the rate for your specific building), not to "the market went up."

When to bring in a lawyer

Checking the percentage in the calculator and writing the first letter is something most tenants can do themselves. It's worth involving a lawyer if: the landlord doesn't respond to written objections and keeps ignoring the number confirmed by the calculator; the rent dispute is tangled up with a threat of eviction or a withheld deposit and you need to run several tracks at once; the Smart Rental Index calculation for your specific building raises questions you want an official reading on; or the amount in dispute is significant and you want to prepare for a possible RDC appeal in advance.
