Dubai's Real Estate Regulatory Agency (RERA) Rent Calculator is the legally binding benchmark that governs whether a landlord may increase rent on a residential or commercial tenancy, and by how much, in any given renewal cycle.
Key takeaway
The RERA Rent Calculator is anchored in Dubai Law No. 26 of 2007 as amended by Law No. 33 of 2008 and implemented through Decree No. 43 of 2013, which sets a tiered increase scale based on the gap between current rent and market value. Landlords who issue increases outside these tiers, or without the requisite 90-day notice, are exposed to disputes before the Rental Dispute Settlement Centre. Tenants have corresponding rights to challenge unlawful increases and claim over-payments. Both parties should obtain a fresh Calculator output before each renewal cycle, as the benchmark market figures are updated periodically by RERA.
Statutory Foundation: The Dubai Tenancy Laws
Dubai Law No. 26 of 2007 Regulating the Relationship between Landlords and Tenants in the Emirate of Dubai established the foundational regime for residential and commercial tenancies in Dubai, excluding areas governed by free-zone or federal housing rules. The law was amended by Law No. 33 of 2008, which introduced stricter controls on rent increases and conferred wider powers on RERA to regulate rental valuations. These laws apply to all privately owned property in Dubai's onshore jurisdiction and are distinct from the federal civil code provisions that apply residually where no special Dubai law exists.
Decree No. 43 of 2013, issued by His Highness the Ruler of Dubai, specifies the precise percentage caps on rent increases by reference to the gap between a tenant's current rent and the average market rent for comparable properties as determined by the RERA Rent Index. The decree creates five bands: where current rent is more than 40% below market, the landlord may increase by up to 20%; between 31–40% below market, by up to 15%; between 21–30% below market, by up to 10%; between 11–20% below market, by up to 5%; and within 10% of or above market, no increase is permitted. These caps are mandatory and cannot be contractually overridden.
How the RERA Rent Calculator Functions
The RERA Rent Calculator is a publicly accessible online tool maintained by the Dubai Land Department (DLD) through the Dubai REST platform. It accepts inputs including the property type (residential, commercial, or retail), the emirate zone, the precise location or district, the number of bedrooms, and the annual rent currently paid. The Calculator then returns the average, minimum, and maximum rental values for comparable units based on RERA's periodically updated Rent Index, derived from registered lease data submitted to Ejari.
The output of the Calculator is not merely indicative — it is the legal reference point for determining whether a proposed increase falls within the permitted bands under Decree No. 43 of 2013. Courts and the Rental Dispute Settlement Centre treat Calculator outputs as the starting reference when adjudicating disputes about unlawful increases. Practitioners routinely advise clients to generate and preserve a dated PDF screenshot of the Calculator output at the time of each renewal cycle as documentary evidence.
Because the Rent Index is updated by RERA, values can shift between a landlord's notice date and a hearing date. The legally relevant figure is generally the one prevailing at the date the notice was issued. Disputes sometimes turn on which Rent Index version applies, making contemporaneous records critical. Both landlords and tenants should retain their Calculator outputs alongside the Ejari-registered lease agreement.
Notice Requirements and Procedural Obligations
Article 14 of Law No. 26 of 2007, as amended, requires that a landlord wishing to modify any tenancy conditions — including rent — must serve written notice on the tenant at least 90 days before the tenancy's expiry date, unless the lease provides for a longer period. Notice served with fewer than 90 days' lead time is treated as ineffective, meaning the tenancy renews on its existing terms. Landlords often overlook this requirement and then attempt to apply the increase mid-term, which is unlawful.
The notice must specify the proposed new rent and must be delivered by a method that creates evidence of receipt: notarised letter, registered post, or the DLD-approved electronic notification channels. A WhatsApp message or informal email, while admissible as supporting evidence, is generally insufficient on its own to establish the 90-day timeline for regulatory purposes. Tenants who receive a valid notice but believe the proposed figure exceeds the permitted Calculator band should lodge a dispute with the Rental Dispute Settlement Centre before the lease expires.
Ejari Registration and Its Legal Significance
Ejari — the DLD's tenancy contract registration system — is mandatory for all residential leases in Dubai under the applicable DLD administrative instructions. An Ejari-registered contract is a prerequisite for many ancillary processes: DEWA utility connections, visa renewals linked to the property, and the filing of a valid rental dispute before the Rental Dispute Settlement Centre. A lease not registered on Ejari can still be enforced as a contract between the parties, but the absence of registration weakens a party's procedural standing in regulatory proceedings.
For the RERA Rent Calculator to produce accurate results, the property details entered must correspond with the Ejari record. Discrepancies between the physical property and its registered classification — for example, a studio described as a one-bedroom — can distort the Calculator output and generate disputed results. Practitioners advise verifying the property's Ejari classification before relying on any Calculator benchmark in a negotiation or dispute.
Commercial and Retail Tenancies: Specific Considerations
Commercial tenancies in Dubai's onshore jurisdiction are governed by the same Law No. 26 of 2007 framework as residential leases, including the 90-day notice requirement and the Decree No. 43 of 2013 increase bands. However, the RERA Rent Calculator for commercial premises uses different benchmarking categories — office, retail, warehouse, and industrial — and the market data sets for these categories can produce materially different results than residential comparables. Parties to commercial leases should not assume that a residential Calculator output has any relevance to a commercial property dispute.
Retail tenancies in major malls are typically structured as turnover-linked or hybrid leases and may fall partly outside the standard RERA rent-cap regime where the parties have contractually embedded legitimate variable rent mechanics. Nevertheless, the base fixed rent component remains subject to the statutory cap. Legal advice is essential before structuring any hybrid commercial lease intended to sidestep the cap framework, as RERA and the Rental Dispute Settlement Centre have consistently applied the statutory bands to fixed-rent components regardless of lease labelling.
Rental Dispute Settlement Centre: Jurisdiction and Process
The Rental Dispute Settlement Centre (RDSC), established under Dubai Decree No. 26 of 2013, is the exclusive first-instance forum for tenancy disputes in Dubai's onshore areas. Its jurisdiction covers rent increase disputes, eviction claims, maintenance obligations, security deposit recovery, and lease interpretation. The RDSC operates as a specialist judicial body and its judgments are enforceable through DLD's execution mechanisms. The Centre is procedurally distinct from the Dubai Courts, although its decisions are subject to appeal through a dedicated appellate committee and ultimately to the Court of Cassation.
A claimant files a dispute application online through the RDSC portal, attaches the Ejari certificate, lease agreement, and the RERA Calculator output showing the alleged over-charge, and pays a filing fee calculated as a percentage of the disputed rent amount. The Centre's mediators attempt settlement at a first session; if unsuccessful, the matter proceeds to adjudication. The RDSC commonly issues interim orders freezing an eviction pending resolution of a rent dispute, providing tenants with meaningful interim protection.
Practitioners note that the RDSC's timelines have improved significantly and most residential disputes are resolved within 30 to 60 days at first instance. However, commercial disputes involving larger sums and complex lease structures can extend considerably longer, particularly where valuation experts are appointed. Parties should preserve all communications, notices, rent receipts, and Calculator outputs from the outset, as the Centre places substantial weight on contemporaneous documentary evidence.
Eviction Grounds and the Interaction with Rent Disputes
A landlord seeking to evict a tenant at the end of a lease term must rely on one of the grounds specified in Article 25 of Law No. 26 of 2007 as amended. These grounds include demolition or reconstruction requiring a building permit, owner-occupation for personal or first-degree family use, or sale of the property where vacant possession is required. A landlord cannot use the failure to agree on an increased rent — beyond the Calculator-permitted bands — as a ground for eviction; only genuine statutory grounds suffice.
Where a landlord attempts to leverage an unlawful rent demand by threatening eviction, tenants have recourse to the RDSC and may seek both a declaration that the increase is void and an order for costs. Conversely, tenants who simply refuse to pay an increase that is within the Calculator-permitted bands risk accumulating arrears that do constitute a valid eviction ground. The practical advice for tenants in borderline cases is to pay the undisputed portion of the rent while filing an RDSC application for determination of the correct figure.
Federal and Abu Dhabi Distinctions
Outside Dubai, tenancy regulation varies materially. Abu Dhabi's tenancy framework is governed by Abu Dhabi Law No. 20 of 2006 concerning tenancy relations, and rent increase caps in Abu Dhabi are administered through the Abu Dhabi Department of Municipalities and Transport rather than RERA. Abu Dhabi does not use the same Calculator tool; instead, it maintains its own rental index and permissible increase percentages, which have been subject to periodic adjustment by executive regulation. Practitioners operating across both emirates must apply the correct emirate-specific framework.
At the federal level, the UAE Civil Transactions Law (Federal Law No. 5 of 1985 and its amendments) provides the residual contractual framework for lease agreements but defers to emirate-level special legislation on rent regulation. DIFC and ADGM — the common-law financial free zones — have their own lease regulations and dispute resolution mechanisms, administered respectively by the DIFC Courts and ADGM Courts, and the RERA Calculator and RDSC have no jurisdiction within those zones.
Practical Compliance Checklist for Landlords and Tenants
Landlords should run the RERA Rent Calculator no later than 120 days before lease expiry to allow sufficient time to draft, translate if necessary, and serve a compliant 90-day notice. The notice should cite the Calculator output and the applicable Decree No. 43 of 2013 band as justification for the proposed increase, creating a transparent paper trail that reduces the prospect of an RDSC challenge. Retaining a copy of the Calculator output at the date of notice is essential because index values are not archived publicly by the DLD.
Tenants who believe a proposed increase is unlawful should not simply refuse to renew without formal action. The correct course is to file an RDSC application before the lease expiry, continue paying the existing rent into an escrow or formally documented account, and attend the Centre's mediation session with supporting evidence. A tenant who vacates without disputing an unlawful notice may lose the right to recover any over-paid rent and will have forfeited the lease.
Practical checklist
- Generate and save a dated RERA Rent Calculator PDF output at least 120 days before each lease renewal cycle.
- Serve any rent increase or material tenancy modification notice in writing with at least 90 days' lead time, using a documented delivery method.
- Confirm the property's Ejari registration classification matches the physical unit before relying on a Calculator benchmark in a dispute.
- File any RDSC dispute application before the lease expiry date to preserve interim protection and avoid de facto acquiescence to unlawful terms.
