The landlords don’t put obstacles to these because of any fire risk, but because they don’t want to cede control. In the same way as you are here technically not allowed to attach a flag to your balcony, or put an anti-war poster in your window.
And that’s only a relevant problem, because in Germany a far higher proportion of flats are rented than in the UK. That has to do with work mobility (when you lose your job, you are expected to look in other cities, too), and also with the fact that in Germany, an own custom-built house will often sell at a substantial loss.
