What it means
Longer leases expose both parties to changes in costs and market rents, and a rent review sets a time and method for adjusting the payment rather than leaving every change to a fresh negotiation. Read the term, renewal provision and review clause together.
A fixed review might state an exact annual step, an index-linked review refers to a published measure and a stated base period, and an open-market review uses comparable premises and agreed assumptions, often with an expert process if the parties disagree. None of these labels settles whether local law limits the increase, so calculate the cash effect before signing: a 5% step on an annual rent of AED 240,000 is AED 12,000 more each year, before any other charges.
Dubai requires particular care because Decree No. 43 of 2013 sets maximum increases on renewal of real property leases by bands comparing current rent with the average rent of similar units.
Do not tell a commercial tenant that its contract alone decides the permitted renewal increase. The Dubai Land Department's Smart Rental Index, launched in 2025, focuses on residential buildings according to guidance checked 27 September 2026, and its own guidance says commercial and industrial smart indices are under development.
That limited coverage is a question about the available benchmark, not proof that commercial leases are exempt from statutory controls. For a real property, check the current applicable official index or valuation route, governing law, locality, free-zone regime and renewal date with a qualified adviser.
Review procedure matters as much as the headline percentage, since the lease and governing law can prescribe notice periods, evidence and steps to challenge a figure. A tenant should not stop paying or accept a demand solely on the strength of an online calculator, and should preserve the signed lease and written communications while obtaining advice.
Include service charges, maintenance, insurance and fit-out where relevant, because they are not necessarily rent under a particular cap. Outside Dubai, rules vary, so the same lease wording can produce a different result under another legal regime.
This glossary's arithmetic is a planning example, not a ruling on an actual lease.
In practice
Real-world examples.
Example
An office tenant checks the signed review clause, renewal date and Dubai rules before responding to a proposed increase. It keeps the lease, the landlord's letter and its own calculation together, so an adviser can review the full file quickly.
Example
A warehouse lease links a mid-term review to an index with a stated base month and cap. The operator models the best and worst outcomes in its budget, so a capped increase does not come as a surprise to finance.
Example
A shop landlord collects comparable lease evidence rather than treating an advertised rent as a completed transaction. The evidence shows that recent signed rents sit below the asking figures, so the landlord proposes a smaller increase and keeps the tenant.
Formula
Calculation
Fixed-step rent = current annual rent x (1 + stated increase rate), subject to applicable law and contract.
Worked example. A fictional lease says AED 240,000 rises 5% at an eligible review. The arithmetic gives AED 240,000 x 1.05 = AED 252,000, an additional AED 12,000 for the year or AED 1,000 more each month. That figure is not a legal finding; the review trigger, agreed terms and any statutory limit must also be checked.
Index-linked variant: reviewed rent = current rent x (index at review / index at base). If the base index is 100 and the review index is 104, rent becomes AED 240,000 x 104 / 100 = AED 249,600. If the lease caps the increase at 3%, the cap is AED 240,000 x 1.03 = AED 247,200, so the lower figure applies under that clause.Case study
Seen in the real world.
This illustrative and entirely fictional example follows Cedarworks Studios, an invented Dubai design firm with an office lease. Before renewal, the landlord proposes raising annual rent from AED 240,000 to AED 275,000, citing nearby asking prices. Cedarworks initially reads only its lease clause and assumes there is no commercial rent-increase limit. Its adviser checks the actual tenancy record, renewal date, current Dubai law and the available route for determining average rent of similar premises. The team distinguishes the residential-focused Smart Rental Index from the broader question of whether Decree Number 43 of 2013 caps an office renewal increase.
It also gathers actual comparable lease evidence, not just listings. The parties exchange figures and agree a documented renewal after confirming the applicable process. The proposed rise of AED 35,000 would have been about 14.6% of the current rent (AED 35,000 / AED 240,000). This fictional outcome does not assert that AED 275,000 was lawful or unlawful: the relevant official benchmark and case facts would decide that.
Watch out
Common mistakes.
- Claiming that Dubai's commercial lease renewals depend only on contract wording.
- Treating the residential focus of the Smart Rental Index as an exemption for commercial property.
- Using an asking price or bare percentage without checking the lease and applicable law.
Questions
People also ask.
Does a rent review always raise the rent?
No. The agreed method and applicable law can produce a different result. Some clauses set floors or fixed steps, while market and index terms need their own calculation.
Does Dubai's rent-increase decree apply only to homes?
Its text addresses real property lease renewals generally, and commercial lease guidance says landlord-tenant laws generally apply to office and retail too. Check the actual premises, law and official benchmark.
Is the Smart Rental Index the same as the statutory cap?
No. The current Smart Rental Index focuses on residential buildings; the legal scope of a rent-increase decree is a separate question. Verify the current method for the specific property.
