How much notice must a landlord give before raising rent in Dubai?

In Dubai, a landlord who wants to change any term of the tenancy, including increasing the rent, must notify the tenant well in advance of the contract expiry. Under the governing tenancy law (Law No. 26 of 2007 as amended by Law No. 33 of 2008), the landlord and tenant must agree any change to the rent at least 90 days before the existing contract ends, unless both sides agree otherwise. This means a landlord cannot spring a rent increase on you at the last minute or mid-term, and a renewal at the old rate stands if no valid, timely notice was served. Separately, even with proper notice, the amount of any increase remains capped by the RERA rental index sliding scale in Dubai Decree No. 43 of 2013, so notice alone does not entitle the landlord to any figure they want. If notice was late or the increase exceeds the calculator's limit, you can challenge it at the Rental Dispute Center under Dubai Land Department. Keep dated copies of all communications. You can compare verified UAE tenancy lawyers on LEXAI to assess whether the notice was valid.
