Which paragraph or article or something else explicitly states that a house entrance 5 meters from the boundary is considered a "boundary building" just because it belongs to the garage? I cannot find this regulation, but everyone refers to it.
Art. 7 para. 4 last sentence BayBO* ...
The hallway section is functionally part of the house and may not comply with the distance?
*Edit:
The above-mentioned reference applies only to the old version of the BayBO, which I found searching on my phone, and previously read:
"The structural connection of this boundary building with a main building or another ancillary building is permissible, provided that these buildings individually comply with the distance requirements applicable to them"
According to current law, the argument[B] no longer directly arises from (now) § 6 para. 8 BayBO. It specifies the conditions under which a garage does not have to comply with distance requirements. The connection of buildings is now regulated in a different context under § 6 para. 6 sentence 3 Bavarian Building Code.
If now a part is no longer functionally a garage but a house entrance, in my opinion, a use is added that could, but does not have to, remove the privilege of boundary building, as the building authority’s notes here show. The distances for the hallway as part of the house are also observed depending on the height H.
I would therefore ask the authority again for the exact legal basis and arguments they rely on.
