What is this right?
Landlords cannot raise your rent by any amount they choose. The UAE has rules that limit rent increases:
- Dubai RERA Index: Rent increases in Dubai are governed by the Real Estate Regulatory Agency (RERA) rental index. If your rent is already at market rate, the landlord generally cannot increase it.
- Percentage caps: In Dubai, increases are capped on a sliding scale — for example, if your rent is 11-20% below market value, the maximum increase is 5%. If 21-30% below, the cap is 10%, and so on up to 20%.
- 90-day notice: The landlord must give you at least 90 days' written notice before any rent increase takes effect.
- Abu Dhabi (5% cap is in force): Abu Dhabi reinstated its 5% annual rent cap by Executive Council Resolution No. 14 of 2016 and it remains in force as of 2026. Landlords must give 2 months' notice before contract expiry to vary the rent. Tawtheeq registration is mandatory; fee is 4% of annual rent capped at AED 10,000.
- Dubai Smart Rental Index (1 January 2025): the RERA rental index was replaced by the DLD Smart Rental Index — an AI-driven valuation factoring building quality, amenities, and location. The percentage tiers under Decree 43/2013 are unchanged; only the underlying market benchmark methodology changed. Always recheck your range via the DLD Smart Rental Index calculator at dubailand.gov.ae.
- No mid-lease increases: Rent cannot be increased during the lease term — only at renewal.
When does it apply?
- You are a tenant in Dubai or Abu Dhabi with a registered lease.
- Your lease is up for renewal and the landlord wants to increase the rent.
- Other emirates may have different rules — check with the local municipality.
What to Do If Your UAE Landlord Proposes an Illegal Rent Increase
- Check the RERA rental calculator (available online on the Dubai Land Department website) to see if the proposed increase is legal.
- If the increase exceeds the allowed percentage, reject it in writing and cite the RERA index.
- If you cannot agree, file a case with the Rental Dispute Settlement Centre (RDSC) before the lease expires.
What should you NOT do?
- Do not accept a verbal rent increase — it must be in writing with 90 days' notice.
- Do not agree to an increase above the RERA cap — even if the landlord pressures you.
- Do not leave the property just because the landlord demands more — you have the right to stay at the legal rate.
About Housing Rights in Oman
UAE housing law is set per emirate, not federally. Your lease must be registered — Ejari in Dubai, Tawtheeq in Abu Dhabi — or no dispute body will touch it. Dubai rent increases follow the RERA Rent Index with 90 days' written notice; eviction needs valid grounds and 12 months' notice. Security deposits are typically 5% (unfurnished) or 10% (furnished) of annual rent. Disputes go to the Rental Disputes Settlement Centre (RDSC) in Dubai or the Abu Dhabi Judicial Department (ADJD) in Abu Dhabi.
