NBauO
Abbreviation for Niedersächsische Bauordnung
In short and in plain language
The NBauO is the building code of Lower Saxony, a German state.
It sets rules for buildings. It also says when a permit is needed.
For roofers, one point matters: when a roof is fully renewed, solar panels may be required.
