6 rules for unincorporated Nassau County, New York.
Verified from official government sources
Nassau County defers fence height to local code. Typical Nassau limits are 4 feet in front yards and 6 feet in side and rear yards, measured from finished grade. Corner-lot visibility triangles impose lower limits.
Most Nassau municipalities require a building permit for any fence, even if under 6 feet. Permit fees range from 50 to 200 dollars. Fences in floodplains or historic districts require additional review.
Nassau follows NY common law on shared fences: no statute requires cost-sharing. NY RPAPL 843 (spite fence) prohibits fences over 10 feet built to annoy neighbors. Finished side must face outward in most Nassau villages.
New York State Uniform Code (19 NYCRR Part 1226) and Nassau County municipalities require a 4-foot minimum barrier around all pools holding 24 inches or more of water, with self-closing and self-latching gates.
Corner-lot sight triangles in Nassau County typically limit fences, walls, and hedges to 30 inches tall within 25 to 30 feet of the intersection of two street right-of-ways.
Approved fence materials include wood, vinyl, chain link, wrought iron, and masonry. Barbed wire and electric fences are generally prohibited in residential zones across Nassau County. Historic villages may restrict synthetic materials.
