There was a change to the Bavarian building regulations on February 1, 2021. According to this amendment, the required setback distance is now 0.4 times the building height instead of the previous 1 times the building height. However, this setback must be maintained on all sides (whereas before it only applied to two sides when considering the 16-meter (52.5 feet) privilege). Additionally, the calculation of setback distances on the eaves side has changed: "For roofs with a pitch up to and including 70°, one-third of the roof height will be added to the wall height. For roofs with a pitch over 70°, the full roof height will be added."
Do I understand correctly that one-third of the roof height is added to the wall height, and then 40% of this total is taken as the setback distance? For example, with a wall height of 6 meters (20 feet), a roof height of 5 meters (16.5 feet), and a roof pitch of 45 degrees, the eaves-side setback would be calculated as [6m + (5m / 3)] * 0.4 = 3.07 meters (10 feet), and the gable-side setback as (6m + 5m) * 0.4 = 4.4 meters (14.4 feet).
I am not 100% sure if this is correct or if the eaves-side setback should instead be calculated as 6m * 0.4 + 5m * (1/3) = 4.07 meters (13.4 feet).
I would be very grateful if someone could provide an explanation.

On the eaves side: [6m (19.7 ft) + (5m (16.4 ft) / 3)] * 0.4 = 3.07m (10.1 ft) Correct.

On the gable side: (6m (19.7 ft) + 5m (16.4 ft)) * 0.4 = 4.4m (14.4 ft) Correct, but only at the ridge peak. The required setback areas are no longer rectangular; they follow the wall height instead.

Or on the eaves side, shouldn’t it be 6m (19.7 ft) * 0.4 + 5m (16.4 ft) * 1/3 = 4.07m (13.4 ft)? No.

I have the same question regarding dormers. How are you doing with that?
Please note that each municipality may have its own regulations, and different rules apply for those with populations over 250,000.
