How the cap works
The law never asks what the landlord wants — it asks how far your current rent sits below the average for similar units. Within 10% of the average the answer is simply no increase; the ceiling then steps 5%, 10%, 15% and never passes 20%. The average itself comes from the DLD Rental Index, built from registered Ejari contracts and, since 2025, rated building by building. The same bands govern every sector the DLD calculator has a tab for — residential, commercial, industrial, industrial land and staff accommodation — and this tool serves them all, since both figures are yours to supply.
