Can I exercise my profession / business in the property I found?

That depends on the zoning plan and possibly on the leasehold conditions and lease agreement. The municipal zoning plan lays down which use is permitted on a particular plot of land, for instance, residential, retail, business, office or social use.

Deviation from the zoning plan is sometimes possible with an environmental permit. This way, your company can still be realised in the building you found.

So have an expert assess the zoning plan before you buy or rent a property.
