Can I add a new business activity to my existing license?

Yes, you can add an activity to your trade license in Dubai. This is processed as a license amendment.

Mainland: You must apply to the DET. If the new activity is in a different category (e.g., adding "Contracting" to a "Trading" license), you may need to rent additional space or change your legal structure.
Free Zone: You can add activities (often up to 6 or 7 per license) by paying an amendment fee plus the cost of the new activity.
