Setback Areas Bavarian Building Regulations - Amendments and Changes

Hello,

there was a change (amendment) to the Bavarian Building Code as of 1.2.21. Accordingly, the required setback area is now 0.4 H instead of previously 1 H. However, this must be observed on all sides (not just on 2 sides as before when considering the 16m privilege). In addition, the calculation of the eaves-side setback areas changes: "The height of roofs with a pitch up to and including 70° will in the future be counted as 1/3 of the wall height, those with a pitch of more than 70° will be fully added."

Do I understand it correctly that the roof height is counted as 1/3 towards the wall height and 40% of this sum is taken?
In the following example: wall height 6m, roof height 5m, roof pitch 45 degrees, the eaves-side setback area would be [6m + (5m/3)]*0.4 = 3.07m and on the gable side (6m + 5m)*0.4 = 4.4m.
I am not 100% sure if this is correct or if the eaves-side setback area is actually 6m * 0.4 + 5m * 1/3 = 4.07m.

I would be very grateful if someone could provide an explanation here.

Well, the new version is probably still so new that hardly anyone knows it. I feel similarly about the dormer windows.

Yes.

traufseitig [6m+(5m/3)]*0,4=3,07m

Correct.

giebelseitig (6m+5m)*0,4=4,4m

Correct, but only for the ridge peak. The distance areas are no longer rectangular, but adapt to the wall height.

does it not amount to 6m*0.4+5m*1/3=4.07m on the eaves side after all?

No.

I feel the same way regarding the dormer windows.

How are you doing then?

It should be noted that every municipality can make its own regulations and for those with more than 250,000 inhabitants, different rules apply again.
