New York Consolidated Laws, Real Property Actions and Proceedings Law - RPA § 843. Fences and structures, when private nuisance

Whenever the owner or lessees of land shall erect or shall have erected thereon any fence or structure in the nature of a fence which shall exceed ten feet in height, to exclude the owner or occupant of a structure on adjoining land from the enjoyment of light or air, the owner or occupant who shall thereby be deprived of light or air shall be entitled to maintain an action in the supreme court to have such fence or structure adjudged a private nuisance.  If it shall be so adjudged its continued maintenance may be enjoined.  This section shall not preclude the owner or lessee of land from improving the same by the erection of any structure thereon in good faith.
