RERA Rent Increase Rules: How Much Can a Dubai Landlord Raise Rent?

Dubai landlords must check the RERA Rental Index: if current rent is within 10% of the index average, no increase is allowed. Gaps of 11-40% permit increases up to 20%. Landlords must give 90 days' written notice before the renewal date.

Why RERA Caps Rent Increases

Dubai's rental market is regulated to prevent sudden, unaffordable jumps in rent between renewals. RERA (the Real Estate Regulatory Agency, part of Dubai Land Department) publishes a Rental Index that compares your unit's current rent to the average rent for similar properties in the same area.

This index is the legal reference point for any increase. A landlord cannot simply decide on a number; the allowed percentage is tied directly to how far below market your existing rent sits. This applies to residential and commercial tenancies registered under Dubai's rental law framework.

How the Rental Index Calculator Works

The RERA Rental Index Calculator is a free tool on the Dubai Land Department website. You enter the area, property type, size, and current annual rent, and it returns the average market rent for comparable units nearby.

The calculator then determines your allowed increase band based on the percentage gap. If your rent is within 10% of the index average, you cannot raise it at all this cycle. If it's 11-20% below index, you can increase by up to 5%. A 21-30% gap allows up to 10%, a 31-40% gap allows up to 15%, and anything above 40% below index allows up to 20%. These bands apply per renewal, not cumulatively in one jump.

The 90-Day Notice Requirement

Even if the index supports an increase, you must notify the tenant in writing at least 90 days before the current contract expires. This is a hard requirement under Dubai's tenancy law, and missing the window generally means the increase cannot take effect for that renewal cycle.

Notice should be sent by a method you can prove later, such as registered mail, email with read receipt, or through the tenant portal some property managers use. Verbal agreement to a new rent is not enough if a dispute later goes to the Rental Dispute Settlement Centre (RDSC).

What If the Tenant Disputes the Increase

If a tenant believes the increase exceeds what the index allows, or that proper notice wasn't given, they can file a case with the RDSC before the renewal date. The Centre will check the index calculation and notice timing, and rulings are generally binding unless appealed.

To avoid disputes, run the calculator yourself before sending notice and keep a copy of the output alongside your notice letter. Landlords who can show the index screenshot, the notice date, and the tenant's acknowledgment tend to resolve questions faster and with less friction.

Documenting Increases Across Multiple Units

If you manage more than one unit, tracking which tenancy is up for renewal, what the last agreed rent was, and when the 90-day window opens becomes harder to do from memory or scattered emails. Missing a single notice date on one unit can cost you a full renewal cycle's increase.

This is where a simple per-unit rent schedule helps. RentLedger keeps each tenancy's renewal date, last rent amount, and notice deadline in one place, so you can see at a glance which units need a notice sent in the next 90 days rather than checking each contract individually.

Recording the New Rent for Owner Statements

Once a new rent is agreed and the tenancy contract or Ejari is updated, that new figure should flow through to your own income records immediately, not just to the tenant's paperwork. Inconsistent records between what's agreed and what's collected are a common source of confusion at year-end.

RentLedger's year-end owner statement pulls from the rent schedule you maintain, so an updated rent amount is reflected automatically in the PDF and CSV export. This keeps your records for personal review consistent with what's stated in the renewed Ejari contract, without needing to reconcile two separate systems.

Common Mistakes to Avoid

The most frequent error is sending the increase notice late, after the 90-day window has closed, which usually forces the landlord to wait until the next renewal to apply any increase. Set a reminder well ahead of each contract's expiry rather than relying on memory.

Another mistake is guessing at the allowed percentage instead of running the actual RERA calculator, which can result in an increase that's later reduced or rejected. Always keep a dated copy of the calculator result as supporting evidence, and if a tenant disputes the figure formally, confirm your specific position with a qualified legal advisor rather than relying on general guidance.
