Summary
Nashua limits fences in residential zones to six feet and lets Turnpike-adjacent lots build to 14 feet with a permit; near street corners, fences can't top 1 to 1.5 feet inside the sight triangle.
Wall, fence or similar enclosures shall conform to the following:
A. In residential zoning districts, shall not exceed six feet in height or interfere with traffic circulation.
B. In nonresidential zoning districts, shall not interfere with traffic circulation (no height restriction).
C. Parcels directly adjacent to the Frederick E. Everett Turnpike, including exits and entrances, upon which there are residential uses, may construct boundary fences up to 14 feet in height on the lot line or lot lines, or portion(s) thereof, which directly adjoin the Turnpike. Such Turnpike boundary fences exceeding seven feet in height shall seek a building permit through the Department of Building Safety and can only be constructed upon issuance of said building permit and subject to its conditions, if any.

Full Breakdown
Nashua's zoning code caps fence height at six feet in residential districts and bars any fence from interfering with traffic circulation; nonresidential districts have no height cap but the same traffic-circulation rule applies. Residential lots bordering the Everett Turnpike may build boundary fences up to 14 feet, though anything over seven feet needs a building permit from the Department of Building Safety. Separately, corner lots carry a sight triangle, 20 feet back from the intersection in residential zones, five feet in nonresidential zones, inside which no fence, wall, planting, or sign may rise above one foot (curbed streets) or 1.5 feet (uncurbed streets).
Violations & Fines
Fences exceeding these height and sight-triangle limits are zoning violations enforceable by the City; Turnpike-adjacent fences over seven feet built without a Building Safety Department permit violate § 190-44 separately.
