Do You Need a Permit to Build a Fence in New York City?
Not for most backyard fences. Under DOB rule 1 RCNY 101-14, a fence 6 feet or less in height, measured from the higher of the two adjoining grades, needs no permit at a one- or two-family dwelling, and DOB's homeowner page adds that homeowners may install their own fencing in that case. The catch is that zoning sets a lower ceiling in the places people most want a tall fence: DOB cites the Zoning Resolution at 4 feet for a residential front yard and 6 feet along the side of a corner lot, with the Building Code allowing up to 10 feet only where zoning permits it. NYC311 notes the same 4-foot limit in the lower-density R1 through R5 districts, with an exception for fences built before April 30, 2008, which may be 6 feet. A fence over 6 feet, or any permanent fence at a building that is not a one- or two-family home, is filed with DOB.

How Much Does a Fence Permit Cost in NYC?
Zero for an exempt fence. A fence that needs a permit is filed as an alteration under Administrative Code Table 28-112.2 (as amended by Local Law 128 of 2024, in effect since December 21, 2025). For a one-, two- or three-family home that is a $130 minimum covering the first $5,000 of job cost, plus $2.60 for each additional $1,000: an $8,000 fence files at about $138, a $20,000 one at about $169. In other buildings under seven stories the minimum is $225 for the first $3,000 plus $10.30 per additional $1,000. The plans have to come from a Registered Design Professional (PE or RA), whose fee is separate and not set by DOB.
Height Limits and Where They Come From
Three layers apply. The DOB exemption (6 feet at a one- or two-family home) decides whether you file. The Zoning Resolution decides how tall the fence may be at all: 4 feet in a residential front yard, 6 feet on the side of a corner lot, per DOB's citation of ZR §23-44. The Building Code (§3112.1 as cited by DOB) caps residential-district fences at 6 feet and fences generally at 10 feet. So a 6-foot front-yard fence in an R3 district is exempt from a DOB permit but still a zoning violation. Measure from the higher of the two adjoining grades.
Who Can Install a Fence in New York City?
Homeowners may install their own exempt fence. DOB recommends hiring a licensed land surveyor first so the fence sits inside the property line, and if you hire an installer, that person must hold a Department of Consumer and Worker Protection Home Improvement Contractor license, checkable through DCWP's Instant License Check or 311. Fences are not required between residential properties, so a shared fence is a private agreement with the neighbor, not a code requirement.
How to Get a Fence Permit in New York City
Check height against zoning first
4 ft in a residential front yard, 6 ft on a corner-lot side, 6 ft in residence districts generally. Zoning applies even when no permit is needed.
Confirm the exemption
6 ft or under at a 1- or 2-family home: no DOB filing. Taller, or another building type: file.
Survey the line and check landmark status
DOB recommends a licensed land surveyor; landmarked properties need LPC approval before work.
File if required
A PE or RA files the alteration in DOB NOW. Fee: $130 minimum for the first $5,000 of job cost plus $2.60 per $1,000 above that at a 1-3 family home.
Install with a licensed contractor or yourself
Homeowners may build an exempt fence; a hired installer needs a DCWP Home Improvement Contractor license.
