What types of things that either jut out into your neighbor’s property or affect your neighbor (like a window) can you create a chazaka on if they haven’t complained? It depends on whether or not it’s something we would expect the neighbor to complain about. If it is unlikely they will complain, then their lack of complaint doesn’t enable you to create a chazaka. In each case, what does it mean to create a chazaka? What types of things do they not even have the right to complain about?
