In one line. Dubai caps rent increases by how far your current rent sits below the RERA rental index, from no increase within 10% of the market rate up to a maximum of 20%, and the index was refreshed with more accurate benchmarks in 2026 (RERA, 2026).
Best for. Tenants facing a renewal and landlords setting one, who want to know the legal ceiling.
What you will learn.
- How the rent-increase slabs work
- What the 2026 index changed
- How to check your own cap
- What to do about notice periods
Bottom line. Your rent increase is not a landlord's choice, it is set by how far your rent is below the index. Check the benchmark, do the math, and you know your ceiling.
How the Slabs Work
The tiers. If your rent is within 10% of the index rate, no increase is allowed. From there the cap rises: 5% if you are 11-20% below, 10% if 21-30% below, 15% if 31-40% below, and 20% if more than 40% below (Dubai rental law).
| How far rent is below index | Max increase |
|---|---|
| Within 10% | 0% |
| 11-20% below | 5% |
| 21-30% below | 10% |
| 31-40% below | 15% |
| More than 40% below | 20% |
What the 2026 Index Changed
More accurate benchmarks. The enhanced index reflects actual transactions more closely, which narrows the gap between the benchmark and reality and cuts disputes over increases (RERA, 2026).
Fewer arguments. When the index mirrors the market, both sides can see the permitted increase, so renewals get simpler and disagreements drop.
How to Check Your Cap
- Find the index rate. Check the RERA rental index or the Dubai REST app for a comparable unit in your building or area.
- Compare to your rent. Work out how far below the index your current rent sits.
- Apply the slab. Match the gap to the cap table to get the maximum legal increase.
- Mind the notice. A landlord must give 90 days written notice before renewal to change terms.
The Bottom Line
For tenants. If your rent is near the index, you are protected from a large jump. If it is well below, expect a capped increase, not an open-ended one.
The honest caveat. Index values and rules update, and specific cases vary. Check the current RERA index for your unit and confirm the rule before you negotiate or renew.
"In Dubai, the rent increase is set by the index, not by the landlord's wish. Check the benchmark, apply the slab, and you already know the ceiling."

How much can a landlord raise rent in Dubai?

What changed in the 2026 rental index?
RERA refreshed the index with benchmarks that track real market data more closely, which narrows disputes over increases (RERA, 2026).
How do I find my index rate?
Check the RERA rental index or the Dubai REST app for a comparable unit in your building or area, then compare it to your current rent.
How much notice must a landlord give?
A landlord must give 90 days written notice before the renewal date to change rent or terms.
