Terrace as a fire truck staging area, is it necessary at all?

According to the construction plan, the entire terrace in our row house is designated as a firefighting staging area for the 1st floor. On the other side of the house, as usual, are the parking spaces. In addition, the side terrace entrances are designated as staging areas for the attic (and in the middle houses there is, as usual, an emergency staircase at the roof window).

Now we have learned from the city that the planned dung path, which we actually thought counted as a fire department access, is not necessary at all and in any case ends at parking spaces. If cars are parked there, the fire department cannot get in anyway.

Due to the designated firefighting staging area, it is now somewhat difficult to place a roof there.
Is the staging area even necessary now? As already mentioned, there is no access for the fire department there and as a second escape route one can also exit on the other side of the house.
Or is there another reason?

The area in question is not accessed by the fire department, but is only used for the positioning of the firefighters who hold the rescue sheet under the second escape route for you. Rest assured that they know how to get there. They practice this kind of thing. Which awning will catch you as reliably as a rescue sheet in an emergency: you can also get advice about that at the station. Second escape routes in a single-family house only need to be verified once per living floor, but they may of course be present multiple times.

If you leave the awning outside, it won't catch fire. Murphy's law. Of course, it's not necessary, single-family houses are regularly not accessible at all by the fire truck. With a maximum of 2.5 floors, that's simply not necessary, you'll be rescued by hand or just jump into the front yard.

Thank you for your answers.

What matters to me is that I would like to build a fixed roof on the terrace and thus make this setup area obsolete.

But, as you also say, you only need to have one escape route per floor, and that would then be the other side of the house instead?

If another way is suitable to fulfill the job of the officially designated second rescue route, then you could have the input plans changed accordingly. Can you even decide on your own to build a fixed terrace roof? (I assume you as the buyer of a [REH] in a [Werner] or [Hermann] project).

Don't forget. Depending on the size and federal state, you will have to submit a building application for the [Überdachung].
