The start of a commercial activity must be reported, as well as changes (in terms of location or content) during operation and also the termination.

For certain commercial activities, however, mere notification is not sufficient. In these cases, permits are issued (e.g. for annual and special markets, vending machine operators and amusement arcades).

Weekly markets are also organized and held.

The department is also responsible for supervising the authorized district chimney sweeps.
