If you wish to use public traffic space during construction work or events, you must apply for permission to do so from the local road traffic authority.

If you want to modernize, renovate or create accommodation facilities for trainees in a youth residence, you can receive funding from the Federal Employment Agency.

For larger construction projects, send an advance notice to the responsible occupational health and safety authority at least two weeks before setting up the construction site. You must also display this advance notice visibly on the construction site and adapt it in the event of significant changes.

Official gazettes are published by local authorities to publicize statutes, ordinances and official notices required by law and to provide information on other official notices.
