對fence的說法：
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。
對樹擋住view的說法:
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。

這種事情打官司實在不值得，如果對方在樹上態度出於無心，你不如敞開天窗說亮話，直接解釋原因，實話實說反倒更容易被理解吧，畢竟修剪漂亮以後，對你對他都是好的。
