Fortress wall in residential neighbourhood

My neighbour has built a huge wall around his property. It is so high and solid that it looks like a fortress. We can’t see inside at all, and it feels intimidating. I’m worried about safety and whether this is even allowed. Can someone just build such a wall? I am concerned about illegitimate activities in the compound? Please guide me.

It is positive that you are concerned about safety in the neighbourhood. In general, property owners in Tanzania have the right to build walls and fences around their land, but this right is not unlimited. The Urban Planning Act, Regulations, and municipal by-laws govern construction in residential areas, including boundary walls.

Typically, even wall constructions require approval and permits from local authorities, especially if they exceed standard height limits, which are usually around 2 to 3 metres. The laws specify that walls must also be structurally sound and not pose a danger to neighbours or passers-by. If a wall is excessively high or designed in a way that creates a hostile environment, neighbours may consult the municipal council to confirm whether a permit has been issued. Seek advice from your local government office for further guidance.
