Danbury zoning caps fences and walls at two feet above curb level within a corner lot's sightline triangle, and the city's building code separately requires a certificate of approval for any fence built taller than six feet anywhere in town.
On that portion of a corner lot between the street line intersection and a line connecting the front yard lines extended to the street lines, no planting, fence, wall, or other obstruction to visibility shall be maintained above the level of a plane two (2) feet above the curb level of the intersecting streets. 3.J.

Full Breakdown
Along the sightline triangle at a corner lot, the area between the street-line intersection and a line connecting the extended front yard lines, no fence, wall, or planting may stand taller than two feet above curb level, per Section 3.I.3 of the Zoning Regulations. Outside that triangle, the Zoning Regulations set no blanket front, side, or rear fence-height cap by district; the citywide trigger instead comes from the Code of Ordinances, which requires a $28 certificate of approval, in addition to any building permit, for fences built over six feet high.
Violations & Fines
Blocking the corner sightline triangle is a Zoning Regulations violation the Zoning Enforcement Officer can order corrected; building a fence over six feet without the required certificate of approval is a Building Code violation.
