Can I start a business out of my home?
Many entrepreneurs start working from home and set up a special room in their apartment or house. You should inform your landlord about this. You should also find out from the Amt für Wohnen und Migration (Housing and Migration Office) whether you are even allowed to use your home for business purposes or whether you need a permit to do so. If you are a home owner, you should also obtain approval for working from home in case of doubt.
You also need to consider building, fire protection, and industry-specific regulations such as requirements for practices and rooms in which some form of childcare is offered, or food hygiene regulations for anyone planning to store, process or sell food.
