This can depend on city/local ordinances. A few years ago my roommate at the time owned the house we lived in. He gets a letter from the City of Clive indicating he has 60 days to address/remove the dead trees in his yard as they are a nuisance per city code. Roommate calls the City and finds out a neighbor had called in a complaint about the trees and worried about the safety of their children as the trees were 40+ feet tall and lined the property line. Well, that narrowed it down to the unfriendly next door neighbor. No knock on the door with "hey, we have concerns about some of your trees", just straight to the city. The city worker said he can give some leeway on the 60 days as he had personally inspected the property and knew it would be a costly removal, but one that was necessary due to city code and due to the complaint now on file. Roommate said he would keep in touch and let Clive know when he had a crew scheduled.Absolutely right and the condition of the tree has absolutely nothing to do with it. You can't compel someone to take down a dead tree.
The kicker on top of everything was about 30 days after the notice from the City, that neighbor put their house on the market. They wanted the trees gone before they started showing their house.
