Marwan bin Ghalita, CEO of Dubai's Real Estate Regulatory Agency (Rera) has said the regulator has asked master developers to provide reasons as to why projects have not started on their master developments, Emirates Business has reported. "We are working with master developers to complete audited technical reports on all the projects that are under the master developer's freehold area. Moreover, we are asking them to give clear reasons as to why a developer has not commenced a project since they are aware of what is happening on-site," the Rera chief has told the newspaper.
