RERA Rental Index Dubai: How Rent Increase Caps Work (2026)

Dubai's rent regulation is widely misunderstood by landlords and tenants alike, and misunderstanding it is expensive for both. Here is exactly how it works.

The principle

Dubai does not cap rents at a fixed percentage. It caps increases based on how far below the market average the current rent sits.

The market average is determined by the RERA rental index, maintained by Dubai Land Department and accessible free through the Dubai REST app and the DLD website.

The framework comes from Decree No. 43 of 2013.

The tiers

Read the first row carefully. If your rent is within 10% of the market average, no increase is permitted at all. This is the row that produces most disputes, because landlords assume some increase is always available.

The 90-day rule

Any change to rent or terms requires 90 days' written notice before the tenancy expires.

Miss the deadline and the contract renews on identical terms for another year.

This single administrative failure costs Dubai landlords more money than any other. A landlord entitled to a 15% increase who serves notice 75 days before expiry gets nothing, for a full year.

Practical protection: diarise a reminder 120 days before every tenancy expiry. That is the entire fix.

Note also that the notice must be genuinely served. For rent changes, written notice is required; for eviction under Article 25(2), service must be via notary public or registered post (Article 36).

How to check your permitted increase

1. 1Open the Dubai REST app or the DLD website.
2. 2Find the Rental Index / Rent Increase Calculator.
3. 3Enter the area, property type, number of bedrooms and current annual rent.
4. 4The tool returns the market average and the maximum permitted increase.

Both parties should do this before any renewal conversation. It converts a negotiation into an arithmetic question, which is faster and less contentious for everyone.

What this means for landlords

You cannot reprice to market in one step. A unit let at 45% below market can be raised 20% this year — which may still leave it well below market, requiring several successive years to close the gap.

Buying a tenanted unit at a below-market rent is buying a constrained income stream. This is one of the most common valuation errors in the Dubai secondary market. The unit is worth less than an equivalent vacant unit, and the gap is not one year of forgone rent — it is several.

Vacancy resets the position. A newly vacant unit can be let at market rent. This is why the 12-month notice for owner occupation, and the associated two-year restriction on re-letting after eviction for personal use, exist — to prevent landlords from cycling tenants purely to reset rents.

The index is your evidence. Proposing an increase above the permitted tier invites a dispute you will lose at the Rental Dispute Settlement Centre, plus the fee and the delay.

What this means for tenants

Check the index before accepting any increase. Landlords sometimes propose increases above the permitted tier, occasionally in error.

Check the notice date. An increase notified fewer than 90 days before expiry is not effective, and the contract renews on existing terms.

Insist on Ejari registration. Without it, enforcing your position is substantially harder, and you need it for DEWA, family visa sponsorship and school enrolment.

A below-market rent is a real asset. If you are paying 30% below market, the maximum increase is 10% — so your rent remains well below market next year too. Tenants frequently underestimate the value of staying put in a rising market.

The 2026 context

Dubai's rental growth decelerated sharply during 2026. Annual rental growth ran at roughly 6.2% as at December 2025, falling to approximately 1.5% by April 2026 — apartments +2.1%, villas −1.5%.

Two implications:

For landlords: as market rents flatten, the gap between existing rents and market narrows, which reduces permitted increases mechanically. A landlord who was entitled to 15% in 2023 may be entitled to 0% in 2026 without anything changing except the market average.

For tenants: a flattening market improves your negotiating position at renewal, and villa rents actually fell over the year to April 2026.

Meanwhile Abu Dhabi rental growth remained strong at roughly 12.0% annually in April 2026 — apartments +12.9%, villas +7.7% — a very different picture across the emirate border.

Disputes

Handled by the Rental Dispute Settlement Centre (RDSC), part of DLD.

Process: file a claim with supporting documents; pay a fee (typically 3.5% of annual rent, subject to minimum and maximum limits); attend mediation; if unresolved, receive a judgment.

Timeline: often 30–60 days for a first-instance decision.

What determines outcomes: documentation and correct procedure, far more often than the underlying merits. Landlords lose cases they should win because notice was improperly served or Ejari was not registered. Tenants lose cases because they have no record of the condition at move-in.

Both sides should keep: the Ejari-registered contract, all written notices with dates and proof of service, rent payment records, a dated move-in condition report with photographs, and all correspondence.

The three rules that matter

For landlords: register Ejari, diarise the 90-day notice at 120 days, and check the index before proposing an increase.

For tenants: register Ejari, check the index on receiving any increase notice, and check the notice date.

For buyers: a tenanted unit at a below-market rent has a legally constrained income stream for several years. Price it accordingly.
