Dubai rent increases in 2026: run the official calculator before renewal

What happened

A fresh explainer has renewed attention on how Dubai rent increases are calculated in 2026. This is not a new cap: Decree No. 43 of 2013 remains the legal basis for the percentage bands at lease renewal. Dubai Land Department's live Rental Index service asks for the contract expiry date, property type, area, number of rooms and current annual rent, then returns the applicable result.

The decree sets the maximum renewal increase as follows:

• 0% when the current rent is up to 10% below the average rental value of similar units.
• 5% when it is 11%–20% below the average.
• 10% when it is 21%–30% below the average.
• 15% when it is 31%–40% below the average.
• 20% when it is more than 40% below the average.

Gulf News independently confirms the same bands and the need to use the official Smart Rental Index.

Who is affected

The rules matter to tenants and landlords at renewal. The decree applies to private and public landlords across Dubai, including special development zones and free zones such as the Dubai International Financial Centre. DLD says the index is indicative for a new lease but is the reference when the parties disagree about the permitted increase at renewal.

Why it matters

The percentage is a cap on the existing contractual rent; it is not permission to replace that rent with a portal asking price or immediately move it to the index average. DLD's current guidance says a landlord can increase rent according to the Rental Index and must normally notify the tenant at least 90 days before contract expiry, unless the parties agree otherwise.

What remains uncertain

The exact result depends on the live official index and the details entered for the property. A building's classification can be updated, and a disagreement may require review by the Rental Disputes Centre. This brief is general information, not an individual legal opinion. The official English translation of the decree also states that the Arabic original prevails for legal interpretation.

What to verify

Before renewal, run the property through the official DLD service using the current contract details and save a dated copy of the result. Check when and how the proposed change was notified, compare the amount with the calculator output and verify the current Ejari record. If the parties still disagree, use DLD or Rental Disputes Centre guidance and obtain qualified advice for the specific contract.

Home Pulse takeaway

Treat the official calculator result and notice timing as the decision inputs. An advertisement, broker estimate or nearby asking rent does not by itself establish the lawful renewal increase.
