How the Market Gap Method Works — RERA Decree 43/2013
Dubai's rent increase system is not based on inflation, costs, or a landlord's wish — it is based purely on the gap between your current contract rent and the RERA Smart Rental Index average for comparable properties in your building or area. The bigger the gap, the higher the increase your landlord can legally apply.
0–10% Below Market
0%
No increase permitted. Your rent is already close to market — the law protects you from further increase.
11–20% Below Market
Max 5%
Landlord may increase by up to 5% of your current annual rent.
21–30% Below Market
Max 10%
Landlord may increase by up to 10% of your current annual rent.
31–40% Below Market
Max 15%
Landlord may increase by up to 15% of your current annual rent.
More Than 40% Below Market
Max 20%
Landlord may increase by up to 20%. Only applies to significantly underpriced contracts.
2026 Update — Smart Rental Index: From 2025 onward, the RERA index moved to an AI-powered Smart Rental Index that rates individual buildings on a 1–5 star scale based on age, condition, amenities, and location micro-data. This means the "market average" for your specific building may differ from the area-wide average. Always verify using the official DLD Smart Rental Index at dubairest.ae or the Dubai REST app for your exact building. This calculator uses area-level averages as a reference baseline.

Market Gap Method — FAQ 2026
What is the market gap method for Dubai rent increases? +
The market gap method is the legal basis for calculating rent increases in Dubai under RERA Decree No. 43 of 2013. Instead of allowing landlords to set any increase they want, Dubai law restricts the maximum increase based on a single calculation: how far your current contract rent sits below the RERA Smart Rental Index average for comparable properties in your building or area. The gap is expressed as a percentage — the larger the gap, the higher the permitted increase, up to a hard maximum of 20%. If your rent is within 10% of the market average, no increase is permitted at all. This makes Dubai's system fundamentally different from a flat-cap model like Abu Dhabi's 5% — in Dubai, a tenant paying well below market is more exposed to large increases than a tenant already paying close to market. [web:81][web:83][web:84]
What is the RERA Smart Rental Index and how is it different from the old RERA Calculator? +
The Dubai Land Department introduced the Smart Rental Index in early 2025 as an upgrade to the previous RERA Rental Index calculator. The key difference is that the new index rates individual buildings on a 1–5 star scale using artificial intelligence, incorporating building age, condition, amenities, and maintenance quality alongside transaction data. Previously, the index gave a single average for an entire area. Now, a 5-star building in JVC may have a higher index value than a 1-star building in the same area — meaning landlords in well-maintained buildings may be able to apply higher increases, while tenants in older buildings have lower market benchmarks and thus less exposure to increases. The index is updated regularly with real transaction data via the Ejari registration system. [web:83][web:85][web:86]
My landlord says my rent is 45% below market — how do I verify this? +
Always verify using the official RERA Smart Rental Index — not your landlord's claim. Open the Dubai REST app or visit dubairest.ae, go to the "Rental Index" section, and search for your building by name. The official index result will show the certified market range for your property type and size. Compare this to your current contract rent — the percentage below the index midpoint determines your Decree 43 cap. If your landlord's claimed market figure is significantly higher than the official index result, the official figure governs — not the landlord's figure. A landlord who quotes inflated market comparables to push into a higher cap tier is misrepresenting the legal position. [web:83][web:85][web:88]
My rent is 35% below the market average — my landlord wants 15% but I want to negotiate down. Is this possible? +
Yes — the Decree 43 caps are maximum limits, not automatic entitlements. A landlord who is entitled to increase by 15% under the gap method is not legally required to apply the full 15% — they can apply any amount from 0% to the maximum. This gives tenants room to negotiate. Common negotiation approaches include: offering to renew for a longer term (2 years instead of 1) in exchange for a lower increase; citing the landlord's low maintenance track record or building condition (which affects the Smart Index star rating); or offering to handle certain maintenance costs in exchange for a lower increase. Most Dubai landlords are open to negotiation — the Decree 43 cap is your ceiling, not the inevitable outcome. [web:81][web:84][web:89]
Rents in my area have gone up a lot this year — does my landlord get a bigger increase cap next year? +
Potentially yes — if market rents in your area have risen significantly, and your contract rent remains fixed, the gap between your rent and the new market average widens. This could move you from, say, the 0% band into the 5% or 10% band at your next renewal. This is one of the most important dynamics in the Dubai rental market in 2025–2026, with affordable areas like DSO and Discovery Gardens seeing rent surges of 20–30% — meaning long-term tenants in these areas who previously faced no increase may now face 5–10% increases. This underscores why verifying your exact cap via the official RERA Smart Rental Index before each renewal is essential. [web:81][web:82][web:79]
