Why did my RERA index suddenly jump?

The Smart Rental Index added a building-quality dimension in 2025 — towers are now graded by age, classification and amenities. Premium and newer buildings saw their indexed average rise sharply; older or lower-grade buildings often stayed flat. The Decree 43/2013 brackets did not change, but the comparison number did.

Can I dispute the index value itself?

You can file a complaint with the Dubai Land Department asking them to review the classification of your building if you believe it is wrong. This is separate from disputing the rent increase, and slower. For the rent dispute itself, file at the RDC against the increase as illegal under Decree 43/2013.

My landlord cited the new index for a 20% hike — is it legal?

Only if your current rent is more than 40% below the new index value AND you received 90 days written notice before renewal. The cap is the same 0%/5%/10%/15%/20% bracket structure. A higher index number does not unlock a higher percentage.

My RERA Index Doubled Overnight: Disputing a Smart Rental Index Jump in Dubai

In early 2025 the Dubai Land Department rolled out the Smart Rental Index, an upgrade that grades towers by age, classification and amenities. The result: tenants in premium buildings saw their indexed market average jump 50–80% overnight, and landlords pounced — citing the new number as justification for the biggest legal increase the rule allows.

What Did and Did Not Change

What changed: the comparison number (your building\'s indexed market average).
What did NOT change: Decree 43/2013\'s bracket structure — the maximum any landlord can apply is still 20%, the 90-day notice rule still applies, and the 0%/5%/10%/15%/20% bands are the same.

This is the key insight. A higher index does not unlock a higher percentage. It only changes which band you fall into.

Step 1 — Re-Run the Numbers Now

Use our RERA rent calculator with your current annual rent. The output will show:

The current Smart Rental Index value for your area + property type + bedrooms
The percentage your rent sits below it
The legal maximum increase for your case (which may still be 0% if you are close to the new index)

If you are in Dubai Marina, JVC, Business Bay, or Downtown Dubai — use the dedicated area pages, they are pre-filled with the new index figures.

Step 2 — Verify the 90-Day Notice

Even if the new index allows the increase your landlord wants, the increase is void without 90 days written notice before your renewal date. Many landlords sent informal WhatsApp messages instead of formal notice — that does not count. If the formal notice is missing, your contract renews at the existing rent regardless of the index.

Step 3 — If the Increase Is Illegal, Respond Formally

Generate a Decree 43/2013 response letter (AED 99) citing your calculator result and the 90-day rule. Send it via email and notarized hard copy if possible. Many landlords back down at this stage.

Step 4 — Dispute the Index Itself (Parallel Track)

If you believe your building has been mis-classified (an older tower wrongly graded as premium, an unrenovated unit treated like a renovated one), file a separate complaint with the Dubai Land Department asking for re-classification. This is slower than the RDC track but can permanently lower the indexed value for future renewals.

Step 5 — File at the RDC if the Landlord Refuses

See our RDC filing guide. Filing fee is 3.5% of annual rent (min AED 500, max AED 20,000). Bring your calculator result, your formal response letter, and the landlord\'s notice.

What Not to Do

Do not pay the increase under protest expecting to recover it later — it complicates the legal case.
Do not let the lease lapse without serving a written response — silence can be interpreted as acceptance.
Do not sign a renewal addendum that contains the disputed amount, even temporarily.
