sorry Azzi, let me disagree with you. As per Qatari law, one of the requirements to register a business is to provide the authorities with the physical location of this business. This location must be approved by the Municipality, and given document called "Municipality License". Goverment is quite strict with Office location approvals. From my own experience, authorities rejected business registration due to inappropriate location.

Besides, to run unregistered business is a violation. As you are probably aware, last year Qatar implemented Business Tax. Unregistered business means unpaid tax. I don't think Qatar government would like this matter.
newdxbguy, you can go to Doha Municipality and file your complaint.
