The rating system program was launched in 2015 and covers all new and old buildings in the emirate.
The new rating mechanism is scheduled to be launched next year after approval by the higher authorities.
Under the new index, four-star buildings are classified as "free," meaning there will be no restrictions on rent increases for these buildings, as they are classified in the ultra-luxury segment.
The other categories of buildings will be allowed to raise rents according to policies approved by the authorities.
The new building index will be based on each building's star rating, its quality and the amenities it offers to tenants, industry sources said.
The new rental index will be based on the star rating of each building.
Dubai authorities have already completed the rating of all residential buildings.
The index will initially cover only residential buildings, with villas to be considered at a later stage.
In the year ending September 2022, average rents in Dubai recorded the highest growth rate ever.
According to real estate consultancy CBRE, average rents in Dubai increased by 26.6%.
During this period, average rents for apartments and villas increased by 26.7% and 25.5% respectively.
However, rents in high-end areas such as The Palm Jumeirah grew at a faster rate due to strong demand and the influx of high net worth individuals to the emirate.
