What is the RERA Rental Index, and is it mandatory?

The RERA Rental Index was created under Law No. 1 of 2009. For new lease contracts it is indicative (not mandatory). For contract renewals and rent disputes it is mandatory as the reference for determining the permitted rent increase.

You can access it in two ways:

5. Via the free Rent Increase Calculator at dubailand.gov.ae → e-Services
6. By generating a Rental Index Report directly on the Dubai REST app — where you can search by area name, Ejari contract number, or DEWA premise number and get an instant calculation.

Prosper automatically runs your Rental Index check at renewal time and pre-fills your renewal contract with the RERA-compliant figure — so there's nothing to calculate manually.
