Impact of the New 2026 RERA Calculator Update
A comprehensive breakdown of how the latest structural adjustments to the RERA rent index will physically impact tenant contract renewals across major Dubai communities.
The Direct Answer
If your current rent mathematically sits within 10% of the 2026 RERA benchmark for your specific building tier, your landlord cannot legally raise it by a single dirham during renewal.
The Real Estate Regulatory Agency (RERA) rental index is Dubai’s formalized mathematical engine for dictating permissible rent increases during standard lease renewals. In the highly-anticipated 2026 framework update, the Dubai Land Department (DLD) synchronized the calculator directly with real-time, verified Ejari transactional data to actively curb extreme speculative rent spikes and protect residential tenants from arbitrary hyper-inflation.
1. AI-Driven Building Ratings
Historically, the RERA index struggled to differentiate between building qualities in the same area. For 2026, RERA formally integrated a 1 to 5 Star Rating System directly into the calculator's algorithm.
- 1–2 Stars: Older buildings with basic amenities are capped to lower neighborhood averages. Landlords cannot use area macro-averages to justify spikes.
- 4–5 Stars: Premium towers with elite facilities command higher index baselines, reflecting their true market premium.
2. Percentage Cap Matrix
Rent increases are governed by Decree No. 43 of 2013, which enforces caps based on how far your current rent sits below the market average for your specific building tier.
| Market Difference | Max Legal Increase |
|---|---|
| 0% to 10% below average | 0% (Prohibited) |
| 11% to 20% below average | 5% Cap |
| 21% to 30% below average | 10% Cap |
| 31% to 40% below average | 15% Cap |
| >40% below average | 20% Max Cap |
3. The 90-Day Dispute Trigger
Landlords must formally notify tenants of any rent increase at least 90 days before the contract expires via email, registered post or notary public.
4. Evictions & Tenant Protections
Landlords sometimes issue eviction notices claiming they intend to sell or reclaim the property for personal use. This requires a formal, notarized 12-month notice.
The One-Year Rental Ban
If a landlord evicts for personal use but re-lists the property at a higher rent, the tenant can sue at the RDC. Punitive compensation often equals one entire year’s rent.
5. Property Upgrades
The only legitimate way to bypass RERA limits is via comprehensive renovations. If the DLD concurs that the asset class has shifted (e.g., from 2-star to 4-star luxury), they will issue a new valuation certificate allowing unrestricted premium yields.
6. Checking Your Own Index Rate: Step by Step
Before any renewal negotiation, pull your official number; it takes two minutes and removes all guesswork:
- Open the official RERA rental index via the Dubai REST app or the Dubai Land Department website (dubailand.gov.ae).
- Enter your community, property type and bedroom count: the index returns the average market rent band for comparable units.
- Compare your current rent to that band. If you are less than 10% below the average, the permitted increase is zero; the slab caps above apply as your rent falls further below market.
- Keep the output. A screenshot of the index result dated near your renewal is your primary evidence in any Rental Dispute Centre (RDC) filing.
7. A Worked Renewal Example
Sara pays AED 80,000 for a 1-bedroom whose RERA index average is AED 100,000; she is 20% below market. The slab table permits a maximum 5% increase, so her landlord may raise the rent to at most AED 84,000, and only if he served notice at least 90 days before expiry. A demanded increase to AED 95,000 would be unenforceable at the RDC regardless of market conditions.

8. Outside Dubai: Other Emirates, Other Rules
The RERA index and its slab caps apply to Dubai tenancies only. Each emirate regulates renewals under its own framework. For example, Sharjah law protects tenants from any increase during the first three years of a tenancy, while Abu Dhabi abolished its fixed percentage cap and relies on contract terms and its own dispute committee. Always verify the rules of the specific emirate on your tenancy contract before negotiating.
