In general yes, applications and permits are public documents. I'm not 100% sure about rejections though (maybe somebody can chime in) but in any case you can infer it from the diff of application and permit. Publicly available does not necessarily mean easily accessible: The official way they get published is at the official bulletin board ("Amtstafel") or the official gazette ("Amtsblatt") of the local administrative entity, and usually for a limited amounted of time. Most councils etc. do have electronic versions though.
