Obtain a demolition order against yourself?

A confirmation or certificate is not required if it is attached to a building exempt from procedures.

No, the building to be demolished is attached to a building exempt from procedures. That means no confirmation is required. That's how I would read it. The question is, is the barn exempt from procedures? After all, it collapses according to the structural analysis if the main building is torn down. (You feel like you're dealing with the Schildbürger.)

A confirmation or certificate is not required if an extension is built on procedure-free buildings.

So I read it exactly again, the barn is not a procedure-free building according to Art. 57 para. 1 to 3 BayBO and therefore this sentence unfortunately does not apply.

I have been feeling like one of the Schildbürger for a long time now.....

There are no land charges

Very strange and, as mentioned, not permitted in NRW. I would first request to inspect the files at the building permit authority, possibly ask the caseworkers for their assessment, and only then, if necessary, consult a lawyer.

I would still recommend the little fire... ;).

Kaho674's post is, of course, meant to be satirical.

Not to cause any misunderstandings.

Kaho674's post is of course meant satirically.

So that there are no misunderstandings.

Of course completely satire [emoji3]
