Abu Dhabi Rental Law: How It Differs From Dubai's Tenancy Rules

Abu Dhabi runs its own tenancy framework, separate from Dubai's, and assuming Dubai's rental rules apply just because you're in the same country is a genuine mistake worth avoiding, since the two emirates differ meaningfully on rent increases, registration systems, and notice periods. Abu Dhabi's tenancy relationship is governed by Law No. 20 of 2006 and its amendments, with disputes handled by the Rental Disputes Settlement Committee under the Abu Dhabi Judicial Department, rather than Dubai's Rental Disputes Centre.\n\nThe most consequential difference is how rent increases are capped. Dubai uses an index-based system tied to the RERA Rental Index, where the permitted increase depends on how far your current rent sits below the calculated average market rent for comparable properties, a tiered percentage structure. Abu Dhabi, under Executive Council Resolution No. 14 of 2016, uses a much simpler flat 5% annual cap that applies uniformly to every existing tenant, regardless of how far below market rate their current rent sits. This is a real, structural difference: an Abu Dhabi tenant paying significantly under market rate is still protected by the same 5% ceiling as everyone else, unlike Dubai's system where a bigger gap to market rate can permit a meaningfully larger percentage increase.\n\nRegistration also runs through a different system entirely: Abu Dhabi tenancy contracts are registered through Tawtheeq, administered by relevant municipal authorities, rather than Dubai's Ejari system administered through RERA/DLD. The notice period for a landlord proposing any change to rent or contract terms is also shorter in Abu Dhabi, 60 days before contract expiry, compared to Dubai's 90-day requirement, so if you're used to Dubai's rental calendar, Abu Dhabi's shorter notice window changes when you should expect to hear from your landlord about any planned increase.\n\nOne further protection worth knowing: Abu Dhabi law doesn't recognise a landlord's simple desire to charge a higher rent as valid grounds for ending a registered tenancy, and a 2026 ADREC directive reinforced this further by requiring that a re-let property be offered at the same rent as its most recent registered Tawtheeq contract, regardless of whether the incoming tenant is new, specifically closing a loophole where a landlord might otherwise evict a tenant and immediately re-let at a higher, unrestricted market rate. Given these genuine structural differences, don't assume anything you know about Dubai's tenancy law, the 90-day notice rule, the RERA rent calculator, or Ejari-specific processes, transfers directly to an Abu Dhabi rental; check the Abu Dhabi-specific rule for each situation instead.
