Dubai Rent Increase 2026 — How the RERA Cap Actually Works
What Dubai landlords can legally ask for at renewal: Decree 43 of 2013, the 5-tier cap (0/5/10/15/20%), the 90-day notice rule under Law 26 of 2007 as amended by Law 33 of 2008, and the 2025 Smart Rental Index.
Dubai rent increases at renewal are governed by a clear, published set of rules. Most tenants who push back on excessive increases win — not by negotiating, but by citing the rule. The rules below apply to every Dubai residential tenancy and are binding regardless of what your lease says.
The legal framework
Two pieces of legislation set the framework. Decree No. 43 of 2013, signed by HH Sheikh Mohammed bin Rashid Al Maktoum on 18 December 2013, sets the five-tier cap structure below. Full text on the Dubai Land Department portal. Law No. 26 of 2007 (the Dubai tenancy law), as amended by Law No. 33 of 2008, governs the 90-day notice rule, the bases for eviction, and the regulation of sublets.
The 5-tier cap
Article 1 of Decree 43/2013 sets the cap as follows. The maximum annual increase depends entirely on how far the current rent sits below the published market average for an equivalent unit:
Max annual increase by gap to market
- Within 10% of market0%
- 11–20% below5%
- 21–30% below10%
- 31–40% below15%
- More than 40% below20%
Source: Decree No. 43 of 2013, Article 1. The cap is a ceiling — landlords may demand less. If current rent meets or exceeds market average, the cap is 0%.
The cap is a ceiling, not a floor. If the current rent is at or above the market average, the cap is 0% — no increase is permitted that year.
The Smart Rental Index (2025 update)
On 15 January 2025, the Dubai Land Department launched the Smart Rental Index, replacing the older annual rental index with a real-time, AI-driven system integrated with Ejari. It updates continuously as new Ejari-registered contracts are signed. Look up the market average for your unit on the DLD Rental Index e-service, the Dubai REST app, or the Ejari portal.
The 90-day notice rule
Under Article 14 of Law 26/2007 (as amended by Law 33/2008), any change in lease terms — including a rent increase — must be given to the tenant in writing at least 90 days before the existing contract expires. If the landlord misses the 90-day window, the lease automatically renews on the existing terms — same rent — for a similar period or one year, whichever is less. Gulf News has documented this consequence with reference to the statute.
Timeline
Day −100 to −90
Landlord must serve written notice of any rent change. WhatsApp + email + registered mail all count as written notice.
Day −89 or later
Notice is too late. No increase applies that renewal cycle — lease rolls over at the current rate.
Day 0 (contract expiry)
If notice was timely AND within the cap, the new rent takes effect. If either condition failed, the previous rent continues.

Worked example
Example: a JLT studio tenant currently paying AED 80,000 per year. The Smart Rental Index returns a market average of AED 112,000 for equivalent studios in the same cluster band.
Max annual increase by gap to market
- Within 10% of market0%
- 11–20% below5%
- 21–30% below10%
- 31–40% below15%
- More than 40% below20%
Example case: 28.6% below market → falls in the third tier (21–30%) → 10% max increase → maximum legal new rent AED 88,000.
- Gap: (112,000 − 80,000) ÷ 112,000 = 28.6% below market
- Cap tier: 21–30% below market → up to 10% increase permitted
- Maximum legal new rent: AED 80,000 × 1.10 = AED 88,000
If the landlord in this scenario demands AED 110,000 (a 37.5% jump), that's above the statutory ceiling of AED 88,000. The tenant responding in writing with the Smart Index screenshot and the calculation usually resolves it. If the landlord refuses, the next step is the Rental Dispute Centre.
The Rental Dispute Centre
The Rental Dispute Centre (RDC) is the specialised tribunal under the Dubai Land Department for tenancy disputes. Its main office is at DLD headquarters in Deira. Filing a case costs 3.5% of the annual rent, capped between AED 500 and AED 20,000. The RDC typically refunds 50% of the basic court fee if parties reach an amicable settlement; a full refund-on-winning is not how the fee schedule works.
Sublet — not a grey zone
Article 24 of Law 26/2007 requires the landlord's prior written consent for any sublease. An unauthorised sublet is grounds for eviction under Article 25(1)(b). If you signed your lease with a master tenant rather than the building owner, confirm the master tenant has the owner's written sublet consent before paying anything.
Four moves before your next renewal
- Around 100 days before contract expiry, check the Smart Rental Index for your specific area, building, and bedroom count. Screenshot it.
- Calculate the gap between your current rent and the indexed average. Identify your cap tier and the legal maximum new rent.
- If the landlord's renewal notice arrives under 90 days before expiry, no increase applies that year — the lease renews at the current rate.
- If the proposed increase exceeds the cap, reply in writing with the index screenshot and the calculation. If the landlord refuses to honour the rule, file at the Rental Dispute Centre before the current lease expires.
