Summary
New York City does not impose a cost-sharing 'partition fence' duty on neighbors; boundary fence disputes fall under New York State law. RPAPL 843 makes a fence over 10 feet built to block a neighbor's light or air a private nuisance, and RPAPL 543 treats fences as permissive non-adverse encroachments.
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.
Full Breakdown
Unlike rural town law, New York City does not run a partition-fence cost-sharing program, so neighbors are not statutorily compelled to split the cost of a division fence; cost-sharing is a matter of private agreement. The key boundary protections come from the Real Property Actions and Proceedings Law. RPAPL Section 843 provides that any fence or fence-like structure exceeding ten feet in height, erected to exclude an adjoining owner from the enjoyment of light or air, may be adjudged a private nuisance in supreme court and enjoined, while preserving the right to improve one's land in good faith.
RPAPL Section 543 (added in 2008) provides that the existence of minor non-structural encroachments - specifically including fences, hedges, shrubbery, plantings, sheds, and non-structural walls - is deemed permissive and non-adverse, so such a fence generally cannot ripen into an adverse-possession claim against the neighbor. Within the city, the Department of Buildings still enforces the height caps of Admin Code 27-509 and the front-yard limit of ZR 23-312 regardless of any private boundary arrangement.
Violations & Fines
A boundary fence over 10 feet erected to block light or air may be declared a private nuisance and ordered removed or reduced under RPAPL 843. Disputes over cost-sharing or exact line location are private civil matters resolved in court; the city's role is limited to enforcing zoning and building-code height limits.
