How Much Can My Landlord Increase the Rent? Dubai RERA Rules (2026)

Rent increases in Dubai are not a free-for-all. There is a legal formula, tied to an official index, that sets the maximum a landlord can raise your rent, and it is the same rule whether you are the tenant paying it or the landlord proposing it. Here is exactly how it works in 2026, and how to check your own number in a few minutes.

The rule: increases are capped by how far below market you are

Under Decree No. 43 of 2013, the permitted rent increase depends entirely on how your current rent compares to the average market rent for similar properties, as measured by the RERA rental index. The further below the market you already are, the more a landlord may raise it, in five fixed bands:

• 0% increase if your current rent is less than 11% below the market average (i.e. within 10% of it).
• 5% if your rent is 11% to 20% below market.
• 10% if it is 21% to 30% below market.
• 15% if it is 31% to 40% below market.
• 20% if it is more than 40% below market.

That 20% is the hard ceiling: no residential rent increase in Dubai can legally exceed 20% in a year, no matter how far below market the rent sits.

The notice rule that protects you

A landlord cannot spring an increase on you at renewal. To change the rent (or any other term), they must give you 90 days' written notice before your tenancy contract expires. If they do not serve that notice in time, the contract renews on the same terms. This is the single most useful thing a tenant can know: no valid 90-day notice, no increase this cycle.

How to check your own cap

The increase is only as reliable as the market rent it is measured against, and that comes from the official RERA rental index (now the Smart Rental Index, which factors in building quality and location). You can:

1. Open the Dubai REST app or the Dubai Land Department website and use the rental index calculator.
2. Enter your area, property type, and number of bedrooms to get the average market rent.
3. Compare it to what you currently pay to see which band, if any, applies.

The calculator will tell you the maximum legal increase for your exact property.

The reality check: what people actually pay

The index gives an average, but rents in the same building vary by floor, view, condition, and how recently the contract was signed. To sanity-check whether a proposed rent is really in line with the building, it helps to see what units there are actually registered at on Ejari, not just the index average. That is one of the things Chat DLD can pull for you: message it on WhatsApp and get registered Dubai Land Department sale prices and Ejari rents for any building or community in seconds. Ask your first question at Chat DLD, or explore any area's registered record across Dubai Diligence. If you are weighing a property as an investment, those real rents are also how you work out a true rental yield.

If a landlord asks for more than the rules allow

You do not have to simply accept it. If a landlord demands an increase above what the RERA index permits, you can raise it with the Dubai Land Department, and the Rental Dispute Settlement Centre will review the case and enforce the legal cap. Come with the RERA index result and your current contract, and the numbers speak for themselves.

This is general information, not legal advice. Rental laws and the RERA index are set by the Dubai Land Department and can change, so confirm the current rule for your specific tenancy before acting.
