Article 879 sets the default when your contract is silent, but most Dubai tenancy contracts override it for small items by drawing an explicit line — usually the AED 500–1,000 band — below which the tenant pays and above which the landlord does. Read your own contract’s maintenance clause before assuming the AED 500–1,000 convention applies, because a landlord who wrote a different figure into the lease is not bound by the Dubai norm.
Documentation is what turns a maintenance dispute into something the Rental Dispute Centre can act on: a written request with a date, sent to the landlord, is evidence that they were asked and failed to respond, while a verbal complaint leaves nothing to file. If a landlord refuses a genuine major repair under Article 879, filing at RDC for an order to repair is generally faster than withholding rent, which can itself become grounds for a dispute against you.
