Mobile offices are modular buildings that are installed on the chassis of a truck.

They, like stationary premises, are equipped with the necessary infrastructure and communications (heating, air conditioning, electricity and water supply, sewerage, navigation and video surveillance), built-in furniture.

Mobile CDAS are specially equipped vehicles with full-fledged workplaces for the provision of administrative services.

To ensure comfortable conditions, it is advisable to receive citizens inside the vehicle. From a legal point of view, mobile CDAS are remote workplaces of administrators of administrative service centers, for which appropriate routes and schedules (hours) of reception are defined.
