Boundary construction double garage/carport 6x9m Lower Saxony

You are only allowed to build once max. 6x9m on one boundary. How is it with the neighbor's approval? Can I then also build a carport on the second boundary?

If then probably only with a building encumbrance entry on the neighbor.

As long as the 15m total is not exceeded...:

§ 5 (8) sentence 3 Lower Saxony Building Code: "Structures according to sentence 2 may underrun the distance according to paragraph 2 on a total length of 9 m per property boundary, but on one building plot only on a total length of 15 m."

And how is it if you want to build a carport 1m away from the boundary? Is that even possible, or is it not allowed because of the 3m building setback? The idea is that you can later still access the back wall for painting or similar without walking over the neighbor's property.

Everything within the usual boundary distance, usually 3.0m, is considered boundary construction. Whether the garage is directly on the boundary or has a 2m distance does not matter; both are considered boundary construction and fall under the 15m rule. However, there are now efforts to reduce the required distances in building zones to 2.5m or even 2m boundary distance. With individual approval/neighbor consent or similar, smaller distances can also be permitted.

In principle, a carport can also be built with a distance if you want to reach it for painting - but this is usually not necessary because you are allowed to enter the neighbor’s property for maintenance/repair if there is no other option. This must be reported, but it should work under normal neighborly relations.

The above quote provides you with the answer....

("Hammerschlagsrecht" possibly also a right of access without distance).
