Most NYC fences don't need a permit — the trigger is going over 6 feet in the rear or side yard, or anything over 4 feet in the front yard. Historic district properties are the exception: even a 3-foot fence may require Landmarks Preservation Commission approval before you start. Flood zone properties add DOB flood-resilience requirements to the mix. For a standard 6-foot rear yard fence on a non-historic property, the DOB NOW Express process is fast — typically approved in 1–3 business days.

  • Corner lots have special sight-triangle setback requirements

Frequently Asked Questions

In most residential districts, fences up to 4 feet in the front yard and up to 6 feet in the rear/side yards do not require a permit. However, always check your specific zoning district — some areas have stricter rules, especially in historic districts or flood zones.
Simple fence permits through DOB NOW Express typically process in 1–3 business days. Permits requiring full plan review (historic districts, complex structures) can take 4–12 weeks.
NYC DOB issues violations that include fines of $500–$10,000+ depending on severity. You may be required to remove the fence or obtain a retroactive permit, which is more expensive and time-consuming than getting the permit upfront.
The same height rules apply regardless of fence material. A chain-link fence over 6 feet requires a permit just like a wood or vinyl fence.
