对fence的说法：
If a fence is blocking your view, it may be in violation of a local law. Commonly, local laws limit man-made fences in back yards to six feet high and in front yards to three or four feet. Height restrictions may also apply to natural fences, such as hedges。
对树挡住view的说法:
View ordinances have been enacted by a minority of cities that recognize scenic views as a valuable part of a home purchase--generally cities with ocean views or rustic backdrops. These ordinances give aggrieved homeowners the right to sue to force the neighbor restore the view by trimming or cutting down a tree. The strength of the ordinances varies depending on the city. Some cities have adopted stringent laws that prescribe exactly what type of plants homeowners may grow, while others provide fairly large loopholes through which homeowners can plant types of trees which go over height restrictions. For example, in some cities the ordinance may make an exception for a native species, which would mean that a certain type of tree could block your view with no recourse for you to sue via the ordinance.You will have to research your city's ordinance and determine the relative strength of the law as well as how your circumstances fit the law. Some ordinances require you to pay for the trimming (if the tree was planted before the law was adopted) or prescribes that you must wait until the tree is a certain distance from your home before you can sue。

这种事情打官司实在不值得，如果对方在树上态度出于无心，你不如敞开天窗说亮话，直接解释原因，实话实说反倒更容易被理解吧，毕竟修剪漂亮以后，对你对他都是好的。
